Abstract:
The development of search queries aims to improve relevant results or obtain suitable resources for current or future research, and it often occurs when users are dissatisfied with their search results or have not obtained sufficient results. Language control tools, particularly continuous thesauri, are considered resources for developing search queries. Accordingly, this article attempts to empirically demonstrate the impact of using terms from the ERIC thesaurus on the optimal development of search queries.  For implementation, the "Initial Assessment of Internet Search Skills" questionnaire, the Track4Win software, and the ERIC thesaurus (associated with the ERIC database) were used as data collection tools. A comparison of the pre-test and post-test search stages between the experimental and control groups showed that the use of the ERIC continuous thesaurus plays a significant role in improving queries and search time, and the use of broader, narrower, and related terms from the thesaurus alters retrieval accuracy. Additionally, the use of broader and related terms from the thesaurus increases search time.

Abstract:
This article comprehensively analyzes integrating Artificial Intelligence (AI) and machine learning techniques into high-scalability search systems. We explore AI-powered search's theoretical foundations and practical implementations, focusing on advanced ranking algorithms, natural language processing for query understanding, and optimized distributed architectures. We demonstrate significant improvements in search relevance and efficiency through experiments conducted on a large-scale dataset comprising 100 million web pages and 1 million real-world queries. Our AI-powered system showed a 15% increase in Normalized Discounted Cumulative Gain (NDCG) for complex queries and a 12% improvement in Mean Reciprocal Rank (MRR) for navigational queries compared to traditional keyword-based approaches. We also address critical challenges in maintaining system scalability and performance, including data synchronization, real-time model updates, and resource management in distributed environments. The article further discusses emerging trends, such as graph neural networks and multimodal search capabilities, alongside ethical considerations and data privacy concerns. Our findings provide valuable insights for researchers and practitioners aiming to develop next-generation search platforms capable of handling the increasing complexity and volume of digital information while ensuring responsible AI integration.

Abstract:
Multi-view product image queries can improve retrieval performance over single view queries significantly. In this paper, we investigated the performance of deep convolutional neural networks (ConvNets) on multi-view product image search. First, we trained a VGG-like network to learn deep ConvNets representations of product images. Then, we computed the deep ConvNets representations of database and query images and performed single view queries, and multi-view queries using several early and late fusion approaches. We performed extensive experiments on the publicly available Multi-View Object Image Dataset (MVOD 5K) with both clean background queries from the internet and cluttered background queries from a mobile phone. We compared the performance of ConvNets to the classical bag-of-visual-words (BoWs). We concluded that (1) multi-view queries with deep ConvNets representations perform significantly better than single view queries, (2) ConvNets perform much better than BoWs and have room for further improvement, (3) pre-training of ConvNets on a different image dataset with background clutter is needed to obtain good performance on cluttered product image queries obtained with a mobile phone.

Abstract:
This paper estimates users’ search intents when using the context search engine (CSE) by analyzing submitted queries. Recently, due to the increase in the amount of information on the Web and the diversification of information needs, the gap between user’s information needs and a basic search function provided by existing web search engines becomes larger. As a solution to this problem, the CSE that limits its tasks to answer questions about temporal trends has been proposed. It provides three primitive search functions, which users can use in accordance with their purposes. Furthermore, if the system can estimate users’ search intents, it can provide more user-friendly services that contribute the improvement of search efficiency. Aiming at estimating users’ search intents only from submitted queries, this paper analyzes the characteristics of queries in terms of typical search intents when using CSE, and defines classification rules. To show the potential use of the estimated search intents, this paper introduces a learning to rank into CSE. Experimental results show that MAP (mean average precision) is improved by learning rank models separately for different search intents.

Abstract:
The improvement of global Internet access and the COVID-19 pandemic, which necessitated mass testing of online teaching methods, have forwarded the competition between higher education institutions from the regional level and the struggle for the rich student into the competition for students in all countries. The paper aims to determine the influence of the rating of higher education institutions on the interest of Internet users by conducting a comparative analysis of the popularity of the official names of higher education institutions in search queries in Ukraine and Poland. To do this, a comparative analysis of the change in the interest in leading higher education institutions in Ukraine and Poland in search queries in the Google search engine is carried out. The analysis is performed using the Google Trends web application. As a result, it is found that a high position of the university in the national ranking does not guarantee more search queries about it on the Internet by both national Internet users and users from the neighboring country. In general, Internet users continue to be most interested in universities located in their region at the time of the search.

Journal of AI-Powered Medical Innovations (International online ISSN 3078-1930) 2, no. 1 (2024): 44–59. https://doi.org/10.60087/vol2iisue1.p009.

Abstract:
Enterprise search systems face significant challenges in handling long-tail queries, which constitute a substantial portion of search traffic but often receive inadequate attention in traditional systems. This paper introduces PALM (Personalized Attention-based Language Model), a novel framework designed to enhance long-tail query understanding in enterprise search environments. PALM integrates personalization capabilities with an advanced attention mechanism to improve search accuracy for infrequent queries while maintaining high performance on common queries. The framework employs a unique hierarchical architecture that combines user context, query semantics, and organizational knowledge through a sophisticated attention mechanism. The system features an innovative query embedding approach that adapts to individual user contexts while leveraging collective organizational knowledge. Extensive experiments on a large-scale enterprise dataset, comprising over 5 million queries from 50,000 users, demonstrate PALM's superior performance compared to state-of-the-art baselines. The results show significant improvements across multiple metrics, with a 17.5% increase in MAP for ultra-rare queries and a 10.4% overall improvement in NDCG@10. The framework exhibits robust performance across different organizational units and query types, making it particularly valuable for enterprise environments where query patterns are highly diverse and context-dependent. Our ablation studies confirm the effectiveness of each component in the PALM architecture, while case analyses provide insights into the framework's practical applications.

Abstract:
Keyword search has failed to adequately meet the needs of enterprise users. This is largely due to the size of document stores, the distribution of word frequencies, and the indeterminate nature of languages. The authors argue a different approach needs to be taken, and draw on the successes of dimensional data modeling and subject indexing to propose a solution. They test our solution by performing search queries on a large research database. By incorporating readily available subject indexes into the search process, they obtain order of magnitude improvements in the performance of search queries. Their performance measure is the ratio of the number of documents returned without using subject indexes to the number of documents returned when subject indexes are used. The authors explain why the observed tenfold improvement in search performance on our research database can be expected to occur for searches on a wide variety of enterprise document stores.

Abstract:
There is an increasing adoption of machine learning for encoding data into vectors to serve online recommendation and search use cases. As a result, recent data management systems propose augmenting query processing with online vector similarity search. In this work, we explore vector similarity search in the context of Knowledge Graphs (KGs). Motivated by the tasks of finding related KG queries and entities for past KG query workloads, we focus on hybrid vector similarity search (hybrid queries for short) where part of the query corresponds to vector similarity search and part of the query corresponds to predicates over relational attributes associated with the underlying data vectors. For example, given past KG queries for a song entity, we want to construct new queries for new song entities whose vector representations are close to the vector representation of the entity in the past KG query. But entities in a KG also have non-vector attributes such as a song associated with an artist, a genre, and a release date. Therefore, suggested entities must also satisfy query predicates over non-vector attributes beyond a vector-based similarity predicate. While these tasks are central to KGs, our contributions are generally applicable to hybrid queries. In contrast to prior works that optimize online queries, we focus on enabling efficient batch processing of past hybrid query workloads. We present our system, HQI, for high-throughput batch processing of hybrid queries. We introduce a workload-aware vector data partitioning scheme to tailor the vector index layout to the given workload and describe a multi-query optimization technique to reduce the overhead of vector similarity computations. We evaluate our methods on industrial workloads and demonstrate that HQI yields a 31× improvement in throughput for finding related KG queries compared to existing hybrid query processing approaches.

Abstract:
In this paper novel method is proposed using hybrid of Genetic Algorithm (GA) and Back Propagation (BP) Artificial Neural Network (ANN) for learning of classification of user queries to cluster for effective Personalized Web Search. The GA- BP ANN has been trained offline for classification of input queries and user query session profiles to a specific cluster based on clustered web query sessions. Thus during online web search, trained GA –BP ANN is used for classification of new user queries to a cluster and the selected cluster is used for web page recommendations. This process of classification and recommendations continues till search is effectively personalized to the information need of the user. Experiment was conducted on the data set of web user query sessions to evaluate the effectiveness of Personalized Web Search using GA optimized BP ANN and the results confirm the improvement in the precision of search results.

Abstract:
Code search is a highly required technique for software development. In recent years, the rapid development of transformer-based language models has made it increasingly more popular to adapt a pre-trained language model to a code search task, where contrastive learning is typically adopted to semantically align user queries and codes in an embedding space. Considering that the same semantic meaning can be presented using diverse language styles in user queries and codes, the representation of queries and codes in an embedding space may thus be non-deterministic. To address the above-specified point, this paper proposes an uncertainty-aware contrastive learning approach for code search. Specifically, for both queries and codes, we design an uncertainty learning strategy to produce diverse embeddings by learning to transform the original inputs into Gaussian distributions and then taking a reparameterization trick. We also design a hard negative sampling strategy to construct query-code pairs for improving the effectiveness of uncertainty-aware contrastive learning. The experimental results indicate that our approach outperforms 10 baseline methods on a large code search dataset with six programming languages. The results also show that our strategies of uncertainty learning and hard negative sampling can really help enhance the representation of queries and codes leading to an improvement of the code search performance.

Abstract:
World Wide Web search engines process millions of queries per day from users all over the world. Efficient query evaluation is achieved through the use of an inverted index, where, for each word in the collection the index maintains a list of the documents in which the word occurs. Query processing may also require access to document specific statistics, such as document length; access to word statistics, such as the number of unique documents in which a word occurs; and collection specific statistics, such as the number of documents in the collection. The index maintains individual data structures for each these sources of information, and repeatedly accesses each to process a query. A by-product of a web search engine is a list of all queries entered into the engine: a query log. Analyses of query logs have shown repetition of query terms in the requests made to the search system. In this work we explore techniques that take advantage of the repetition of user queries to improve the accuracy or efficiency of text search. We introduce an index organisation scheme that favours those documents that are most frequently requested by users and show that, in combination with early termination heuristics, query processing time can be dramatically reduced without reducing the accuracy of the search results. We examine the stability of such an ordering and show that an index based on as little as 100,000 training queries can support at least 20 million requests. We show the correlation between frequently accessed documents and relevance, and attempt to exploit the demonstrated relationship to improve search effectiveness. Finally, we deconstruct the search process to show that query time redundancy can be exploited at various levels of the search process. We develop a model that illustrates the improvements that can be achieved in query processing time by caching different components of a search system. This model is then validated by simulation using a document collection and query log. Results on our test data show that a well-designed cache can reduce disk activity by more than 30%, with a cache that is one tenth the size of the collection.

Abstract:
Search Engine Optimization (SEO) is the technique of improving Web sites visibility in search engines. Since the algorithms that search engines are based on become more intelligent each day, there is a constant urge for new knowledge. In collaboration with RankTrail, new research for discovering insights about SEO has been conducted. Hypotheses around alleged ranking factors have been created based on qualitative interviews. Through a quantitative case study these hypotheses have been analyzed. The first part of the analysis consisted of calculating the Spearman’s Rank-Order Correlation. Secondly, these correlations has been visualised using histograms. Additional statistical tests have been performed. Number of images, use of HTTPS and use of a custom meta-description stand out amongst all factors analyzed. All three have a higher mean, but also a higher effect size calculated from Cohen’s d. However, the results of this study show that none of the factors indicate a strong impact on SEO.

Abstract:
Services that once required human interaction are now completed with the click of a few buttons. In general, this allows for a more streamlined process for activities such as sending messages (email or text messages), filing taxes, or even shopping for groceries. In terms of searching for hotels and travel accommodations however, this process has not proven to be the most effective as the speed and efficiency is hindered by the interface through which this information is available. Choosing a travel specific site, filling in the required fields, combing through results for the desired specifications, and then possibly repeating the process elsewhere, does not provide the ability for the user to express the entirety of their preferences for the accommodation and is therefore not an effective method for searching. Natural language search provides a more accessible and intuitive interface for accommodation searching. Instead of specifying fields that may not encompass the the entirety of the desired search, the user is able to express all of the aspects in a single, natural language, search. In this project, we propose a natural language search interface for accommodations such as hotels, hostels, or apartments. Data acquired through Amazon Mechanical Turk is used to create a system for extracting various accommodation fields. Zilyo and Expedia APIs are then queried for real-time accommodation listings. These results are then adjusted based on the specifics of the search that were not included in the original query. A natural language search of this kind is not only more accessible on the consumer end, but provides data that pertains directly to the the entirety of the intended search.

Abstract:
Named Entity Recognition and Classification is the task of extracting from text, instances of different entity classes such as person, location, or company. This task has recently been applied to web search queries in order to better understand their semantics, where a search query consists of linguistic units that users submit to a search engine to convey their search need. Discovering and analysing the linguistic units comprising a search query enables search engines to reveal and meet users' search intents. As a result, recent research has concentrated on analysing the constituent units comprising search queries. However, since search queries are short, unstructured, and ambiguous, an approach to detect and classify named entities is presented in this thesis, in which queries are augmented with the text snippets of search results for search queries. The thesis makes the following contributions: 1. A novel method for detecting candidate named entities in search queries, which utilises both query grammatical annotation and query segmentation. 2. A novel method to classify the detected candidate entities into a set of target entity classes, by using a seed expansion approach; the method presented exploits the representation of the sets of contextual clues surrounding the entities in the snippets as vectors in a common vector space. 3. An exploratory analysis of three main categories of search refiners: nouns, verbs, and adjectives, that users often incorporate in entity-centric queries in order to further refine the entity-related search results. 4. A taxonomy of named entities derived from a search engine query log. By using a large commercial query log, experimental evidence is provided that the work presented herein is competitive with the existing research in the field of entity recognition and classification in search queries.

Abstract:
The main contribution of this thesis is to deepen and generalize previous work done in the average-case analysis of partial match queries in several types of multidimensional search trees. In particular, our focus has been the analysis of fixed PM queries. Our results about them generalize previous results which covered the case where only one coordinate is specified in the PM query- and for any dimension-or the case of 2-dimensional data structures. Using a combinatorial approach, different to the probabilistic approaches used by other researchers, we obtain asymptotic formulas for the expected cost of fixed PM queries in relaxed and standard K-d trees. We establish that, in both cases, the expected cost satisfies a common pattern in the relationship with the expected cost of random PM queries. Moreover, the same pattern appeared in the analysis, previously done by other researchers, of the expected cost of fixed partial match in 2-dimensional quad trees. Those results led us to conjecture that such formula would be pervasive to describe the expected cost of partial match queries in many different multidimensional trees, assuming some additional technical conditions about the family of multidimensional search trees under consideration. Indeed, we prove this to be the case also for K-dimensional quad trees. However, we disprove that conjecture for a new variant of K-d trees with local balancing that we define: relaxed K-dt trees. We analyze the expected cost of random PM queries and fixed PM queries in them and, while we do not find a closed-form expression for the expected cost of xed PM queries, we prove that it cannot be of the same form that we had conjectured. For random PM queries in both relaxed and standard K-dt trees, we obtain two very general results that unify several specific results that appear scattered across the literature. Finally, we also analyze random PM queries in quad-K-d trees -a generalization of both quad trees and K-d trees- and obtain a very general result that includes as particular cases previous results in relaxed K-d trees and quad trees.<br>La principal contribución de esta tesis es profundizar y generalizar resultados anteriores referentes al análisis en caso medio de búsquedas parciales en varios tipos de árboles multidimensionales de búsqueda. En particular nos enfocamos en el análisis de búsquedas parciales fijas. Nuestros resultados sobre ellas generalizan resultados previos que cubren el caso donde solamente una coordenada es especificada en la búsqueda parcial-y para cualquier dimensión-o el caso de estructuras de datos de dos dimensiones. Usando un enfoque combinatorio, diferente a los enfoques probabilísticos utilizados por otros investigadores, obtenemos fórmulas asintóticas para el costo esperado de búsquedas parciales fijas en árboles K-d relajados y estándares. Establecemos que, en ambos casos, el costo esperado satisface un patrón común en la relación con el costo esperado de búsquedas parciales aleatorias. Además, el mismo patrón apareció en el análisis, previamente hecho por otros investigadores, del costo esperado de búsquedas parciales fijas en quadtrees de dos dimensiones. Esos resultados nos llevaron a conjeturar que tal fómula sería generalizada para describir el costo esperado de consultas de búsqueda parcial en muchos árboles multidimensionales diferentes, asumiendo algunas condiciones técnicas adicionales sobre la familia de árboles multidimensionales de búsqueda bajo consideración. De hecho, demostramos que este también es el caso en quadtrees de K dimensiones. Sin embargo, definimos una nueva variante de árboles K-d con reorganizacion local que cumplen tales condiciones, los árboles K-dt relajados, analizamos el costo esperado de búsquedas parciales aleatorias y fijas en ellos y, aunque no encontramos una expresión cerrada para el coste esperado de las búsquedas parciales fijas, demostramos que no puede ser de la misma forma que habíamos conjeturado. También obtenemos dos resultados muy generales para busquedas parciales aleatorias en árboles K-dt relajados y estándares que unifican varios resultados específicos que aparecen dispersos en la literatura. Finalmente, analizamos búsquedas parciales aleatorias en una generalizacion de quadtrees y árboles K-d, llamada árboles quad-K-d, y obtenemos un resultado general que incluye como casos particulares resultados previos en árboles K-d relajados y quadtrees.<br>Són moltes les aplicacions en què es requereix administrar col·leccions de dades multidimensionals, en les quals cada objecte és identificat per un punt en un espai real o abstracte; un exemple paradigmàtics són els sistemes d’informació geogràfica. Aquestes aplicacions fan servir sovint estructures de dades multidimensionals que permetin consultes associatives -aquelles on s'especifiquen condicions per a més d'una coordenada- a més de les operacions tradicionals d’inserció, actualització, eliminació i cerca exacta. Un dels principals tipus de consultes associatives és la cerca parcial, on només s'especifiquen algunes coordenades i l'objectiu és determinar quins objectes coincideixen amb elles. Les consultes de cerca parcial són particularment importants perquè la seva anàlisi forma la base de l’anàlisi d'altres tipus de consultes associatives, com ara les cerques per rangs ortogonals (quins punts estan dins d'una àrea (hiper)rectangular donada?), les consultes per regió (per exemple, donats un punt i una distància, quins punts estan a aquesta distància o menys d'aquest punt?) o les consultes del veí més proper (on cal trobar els k punts més propers a un punt donat). En aquesta tesi analitzem en profunditat el rendiment mitjà de les cerques parcials en arbres multidimensionals de cerca representatius, els quals constitueixen una subclasse significativa de les estructures de dades multidimensionals. Els arbres multidimensionals de cerca, en particular els quadtrees i els arbres K-d, van ser definits a mitjans de la dècada dels anys 1970 com una generalització dels arbres binaris de cerca. Les consultes de cerca parcial s'hi responen realitzant un recorregut recursiu d'alguns subarbres. Durant molts anys l’anàlisi en arbres multidimensionals de cerca es va fer amb la suposició important, i sovint implícita, que en cada crida recursiva es generen a l'atzar noves coordenades de la consulta de cerca parcial. La raó d'aquesta suposició simplificadora va ser que, per als costos mitjans, aquesta anàlisi és equivalent a analitzar el rendiment de l'algorisme de cerca parcial quan l'entrada és una consulta de cerca parcial aleatòria. A principis d'aquesta dècada, alguns equips van començar a analitzar el cas mitjà de cerques parcials sense aquesta suposició: les coordenades especificades de la consulta romanen fixes durant totes les crides recursives. Aquestes consultes s'anomenen cerques parcials fixes. L'objectiu d'aquest enfocament recent és analitzar el rendiment de l'algorisme de cerca parcial, però ara les quantitats d’interès depenen de la consulta particular q donada com a entrada. L’anàlisi de cerques parcials fixes, juntament amb el de les aleatòries -que té un paper important per a l’anàlisi de les primeres- ens dóna una descripció molt detallada i precisa del rendiment de l'algorisme de cerca parcial que podria ser estesa a altres consultes associatives rellevants. La principal contribució d'aquesta tesi és aprofundir i generalitzar resultats previs referents a l’anàlisi en cas mitjà de les cerques parcials en diversos tipus d'arbres multidimensionals de cerca. En particular ens enfoquem en l’anàlisi de les cerques parcials fixes. Els nostres resultats en generalitzen resultats previs els quals cobreixen el cas on només una coordenada està especificada a la cerca parcial i per a qualsevol dimensió no el cas d'estructures de dades de dues dimensions. Usant un enfocament combinatori, diferent als enfocaments probabilístics utilitzats per altres investigadors, obtenim fórmules asimptòtiques per al cost esperat de cerques parcials fixes en arbres K-d relaxats i estàndards. Establim que, en tots dos casos, el cost esperat satisfà un patró comú en la relació amb el cost esperat de cerques parcials aleatòries. A més, el mateix patró va aparèixer en l’anàlisi, prèviament fet per altres investigadors, del cost esperat de cerques parcials fixes en quadtrees de dues dimensions. Aquests resultats ens van portar a conjecturar que tal fórmula seria general per descriure el cost esperat de consultes de cerca parcial en molts arbres multidimensionals diferents, assumint algunes condicions tècniques addicionals sobre la família d'arbres multidimensionals de cerca sota consideració. De fet, demostrem que aquest és també el cas pels quadtrees de K dimensions. Tanmateix, definim una nova variant de arbres K-d amb equilibri local que compleixen aquestes condicions, els arbres K-dt relaxats, n'analitzem el cost esperat de cerques parcials aleatòries i fixes i, tot i no trobar una expressió tancada per al cost esperat de les cerques parcials fixes, demostrem que no pot ser de la mateixa forma que havíem conjecturat. També obtenim dos resultats molt generals per a les cerques parcials aleatòries en arbres K-dt relaxats i estàndards, els quals unifiquen diversos resultats específics que apareixen dispersos a la literatura. Finalment, analitzem cerques parcials aleatòries en una generalització de quadtrees i arbres K-d, anomenada arbres quad-K-d, i obtenim un resultat general que inclou com a casos particulars resultats previs en arbres K-d relaxats i quadtrees

Abstract:
In this project, we design a search query optimization system based on the user’s relevance feedback by generating customized query strings for existing patent alerts. Firstly, the Rocchio algorithm is used to generate a search string by analyzing the characteristics of related patents and unrelated patents. Then the collaborative filtering recommendation algorithm is used to rank the query results, which considering the previous relevance feedback and patent features, instead of only considering the similarity between query and patents as the traditional method. In order to further explore the performance of the optimization system, we design and conduct a series of evaluation experiments regarding TF-IDF as a baseline method. Experiments show that, with the use of generated search strings, the proportion of unrelated patents in search results is significantly reduced over time. In 4 months, the precision of the retrieved results is optimized from 53.5% to 72%. What’s more, the rank performance of the method we proposed is better than the baseline method. In terms of precision, top10 of recommendation algorithm is about 5 percentage points higher than the baseline method, and top20 is about 7.5% higher. It can be concluded that the approach we proposed can effectively optimize patent search results by learning relevance feedback.

Abstract:
Parametric search, invented by Nimrod Megiddo in 1983, is a complex yet powerful technique for solving general optimisation problems. It has since become a cornerstone technique in computational geometry and has led to efficient algorithms for a wide variety of problems. In this thesis, we apply parametric search to voting games and Fréchet queries. The connection between voting games and computational geometry is a relatively recent one, and as such, geometric optimisation techniques are not commonly used for solving problems in voting games. We apply parametric search to compute the yolk, which is an important concept in spatial voting games. The connection between the Fréchet distance and parametric search is much more well understood. Our contribution is using repeated inductive applications of parametric search to achieve efficient queries for a variant of a Fréchet distance problem.

Abstract:
Query spelling correction is an important component of modern search engines that can help users to express their intent, and thus improve search quality. In this study, we investigated with what accuracy a sequence-to-sequence recurrent neural network (RNN) can recognise and correct misspellings in a music search engine, when the model is trained with old search queries. A sequence-to-sequence RNN was chosen as the model in this study since it has achieved state-of-the-art performance on similar tasks, such as machine translation and speech recognition. The findings from the study imply that the model learns to correct and complete queries with higher accuracy compared to a baseline model that returns the input query. However, we suggest that, for a model that would be good enough for production, more work needs to be done. Especially, work on creating a cleaner, less biased training dataset. Nevertheless, our work strengthens the idea that sequence-to-sequence RNNs could be used as a spell correction system in search engines.<br>Stavningskorrigering av söksträngar är en viktig komponent i moderna sökmotorer. Stavningskorrigering kan hjälpa användarna att uttrycka sig och därmed förbättra kvaliteten i sökningen. I det här arbetet undersökte vi med vilken noggrannhet en Recurrent neural network (RNN) modell kan lära sig att korrigera felstavningar i söksträngar från en sökmotor för musik. RNN modellen tränades med söksträngar från historiska sökningar från sökmotorn. Anledningen till att RNN valdes som modell i den här studien var för att den har uppnått hittills bästa möjliga resultat på liknande uppgifter, såsom maskinöversättning och taligenkänning. Resultaten från vår studie visar att modellen lär sig att korrigera och komplettera söksträngar med högre noggrannhet än en basmodell som enbart returnerar indatasträngen. För att utveckla en modell som är tillräckligt bra för produktion föreslår vi emellertid att mer arbete måste utföras. Framför allt är vi övertygade om att ett renare, mindre systematiskt avvikande träningsdataset skulle förbättra modellen. På det hela taget stärker dock vårt arbete hypothesen att RNN modeller kan användas som stavningskorrigeringssystem i sökmotorer.

Abstract:
While Learning to Rank (LTR) is widely employed in web searches to prioritize pertinent webpages from the retrieved contents based on input queries, traditional LTR models stumble over two principal stumbling blocks leading to subpar performance: 1) the lack of well-annotated query-webpage pairs with ranking scores to cover search queries of various popularity, debilitating their coverage of search queries across the popularity spectrum, and 2) ill-trained models that are incapable of inducing generalized representations for LTR, culminating in overfitting. To tackle above challenges, we proposed a Generative Semi-supervised Pre-trained (GS2P) LTR model. Specifically, GS2P first generates pseudo-labels for the unlabeled samples using tree-based LTR models after a series of co-training procedures, then learns the representations of query-webpage pairs with self-attentive transformers via both discriminative and generative losses. Finally, GS2P boosts the performance of LTR through incorporating Random Fourier Features to over-parameterize the models into "interpolating regime", so as to enjoy the further descent of generalization errors with learned representations. We conduct extensive offline experiments on a publicly available dataset and a real-world dataset collected from a large-scale search engine. The results show that GS2P can achieve the best performance on both datasets, compared to baselines. We also deploy GS2P at a large-scale web search engine with realistic traffic, where we can still observe significant improvement in real-world applications.

Abstract:
Entity recommendation, providing search users with an improved experience by assisting them in finding related entities for a given query, has become an indispensable feature of today's Web search engine. Existing studies typically only consider the query issued at the current time step while ignoring the in-session preceding queries. Thus, they typically fail to handle the ambiguous queries such as "apple" because the model could not understand which apple (company or fruit) is talked about. In this work, we believe that the in-session contexts convey valuable evidences that could facilitate the semantic modeling of queries, and take that into consideration for entity recommendation. Furthermore, in order to better model the semantics of queries, we learn the model in a multi-task learning setting where the query representation is shared across entity recommendation and context-aware ranking. We evaluate our approach using large-scale, real-world search logs of a widely used commercial Web search engine. The experimental results show that incorporating context information significantly improves entity recommendation, and learning the model in a multi-task learning setting could bring further improvements.

Abstract:
Abstract Managing and referencing design knowledge is a critical activity in the design process. However, reliably retrieving useful knowledge can be a frustrating experience for users of knowledge management systems due to inherent limitations of standard keyword-based searches. In this research, we consider the task of retrieving relevant lessons learned from the NASA Lessons Learned Information System (LLIS). To this end, we apply a state-of-the-art natural language processing (NLP) technique for information retrieval (IR): semantic search with sentence-BERT, which is a modification of a Bidirectional Encoder Representations from Transformers (BERT) model that uses siamese and triplet network architectures to obtain semantically meaningful sentence embeddings. While the pre-trained sBERT model performs well out-of-the-box, we further fine-tune the model on data from the LLIS so that it learns on design engineering-relevant vocabulary. We quantify the improvement in query results using both standard sBERT and fine-tuned sBERT over a keyword search. Our use case throughout the paper is to use queries related to specific requirements from a NASA project. Fine tuning the sBERT model on LLIS data yields a mean average precision (MAP) of 0.807 on queries based on information needs from a real NASA project. Results indicate that applying state-of-the-art natural language processing techniques, especially when fine-tuned using engineering data, to design information retrieval tasks shows significant promise in modernizing design knowledge management systems.

Abstract:
Neural link predictors are useful for identifying missing edges in large scale Knowledge Graphs. However, it is still not clear how to use these models for answering more complex queries containing logical conjunctions (∧), disjunctions (∨), and existential quantifiers (∃). We propose a framework for efficiently answering complex queries on in- complete Knowledge Graphs. We translate each query into an end-to-end differentiable objective, where the truth value of each atom is computed by a pre-trained neural link predictor. We then analyse two solutions to the optimisation problem, including gradient-based and combinatorial search. In our experiments, the proposed approach produces more accurate results than state-of-the-art methods — black-box models trained on millions of generated queries — without the need for training on a large and diverse set of complex queries. Using orders of magnitude less training data, we obtain relative improvements ranging from 8% up to 40% in Hits@3 across multiple knowledge graphs. We find that it is possible to explain the outcome of our model in terms of the intermediate solutions identified for each of the complex query atoms. All our source code and datasets are available online (https://github.com/uclnlp/cqd).

Abstract:
Abstract Data is at the heart of Digital Transformation whether it is generated by legacy systems, a word processor, or state-of-the-art sensors. This makes it harder for Upstream professionals to find the right information for operational needs and making decisions. In this work, we describe an approach that utilizes Enterprise Search, AI and Computer Vision to construct a single efficient search layer, called USEARCH, over multiple data repositories. This enables Upstream professionals to perform searches using simple business language and get the information they need wherever it resides. Our approach to build USEARCH consists of five steps. First, establishing a search infrastructure. Second, indexing content and metadata of documents to make them easily searchable from a single layer regardless of the source repository. Third, utilizing Artificial Intelligence to intelligently tag information within data and documents such as wells, reservoirs and business process labels. Fourth, applying Computer Vision techniques to extract tabular information from documents. Fifth, developing an intuitive user interface to simplify finding data. It can intelligently set the business context based on user domain such as Exploration, Drilling or Petroleum Engineering. We applied our approach on over 3 million documents of different types such as drilling reports, reservoir studies, well test analysis, biostratigraphy and geological maps and stored on multiple repositories. This results in a massive improvement. Upstream professionals can now find data through a single layer and thus eliminate the overhead of switching searches between repositories. In addition, multiple search queries that used to take minutes have now been replaces by a single query that takes a few seconds and even milliseconds in some cases. Furthermore, search results are displayed in a business context with direct links to data at the source repositories. The application of Computer Vision allows any tabular data within documents to be exported to databases for fast analysis. Our approach connects all different data repositories and provides user with an intuitive user interface to find data. This unleashes the potential of Upstream data and empowers Upstream analysts to spend more time using data than finding it.

Abstract:
Dyna is an architecture for model based reinforcement learning (RL), where simulated experience from a model is used to update policies or value functions. A key component of Dyna is search control, the mechanism to generate the state and action from which the agent queries the model, which remains largely unexplored. In this work, we propose to generate such states by using the trajectory obtained from Hill Climbing (HC) the current estimate of the value function. This has the effect of propagating value from high value regions and of preemptively updating value estimates of the regions that the agent is likely to visit next. We derive a noisy projected natural gradient algorithm for hill climbing, and highlight a connection to Langevin dynamics. We provide an empirical demonstration on four classical domains that our algorithm, HC Dyna, can obtain significant sample efficiency improvements. We study the properties of different sampling distributions for search control, and find that there appears to be a benefit specifically from using the samples generated by climbing on current value estimates from low value to high value region.

Abstract:
In recommender systems, preference elicitation (PE) is an effective way to learn about a user's preferences to improve recommendation quality. Expected value of information (EVOI), a Bayesian technique that computes expected gain in user utility, has proven to be effective in selecting useful PE queries. Most EVOI methods use probabilistic models of user preferences and query responses to compute posterior utilities. By contrast, we develop model-free variants of EVOI that rely on function approximation to obviate the need for specific modeling assumptions. Specifically, we learn user response and utility models from existing data (often available in real-world recommender systems), which are used to estimate EVOI rather than relying on explicit probabilistic inference. We augment our approach by using online planning, specifically, Monte Carlo tree search, to further enhance our elicitation policies. We show that our approach offers significant improvement in recommendation quality over standard baselines on several PE tasks.

Full text
Abstract:
Web-enabled LLMs routinely answer queries without crediting the pages they consume, creating an “attribution gap” – the difference between relevant URLs visited and those cited. Using 14,000 real-world LMArena logs from search-enabled LLM systems, we highlight three modes of exploitation online: 1) Skipping web search altogether (34% of Google Gemini model answers, 24% of OpenAI’s GPT-4o model answers); 2) Omitting citations entirely – Gemini supplies no clickable citations in 92% of responses; 3) High-volume exploitation: Perplexity’s Sonar visits approximately a dozen relevant pages when searching but credits only a few. Our statistical model finds that for an average query answered by Gemini and Perplexity ≈ 3 relevant websites go uncited, whereas GPT-4o’s much smaller gap appears to reflect limited disclosure of its relevant browsing trace. Citation efficiency differences between models (citations per extra page visited) vary sharply by specific model – from 0.19 to 0.45 on identical queries – indicating that retrieval design, not technical constraints, shapes ecosystem impact. Richer retrieval logs, machine-readable licenses, and standardized attribution protocols could realign incentives toward content creators.

Abstract:
Remittances constitute a significant safety net for millions of households in Latin America and the Caribbean (LAC). Consequently, changes in international transfers can be a crucial agent of transmission of the COVID-19 induced economic crisis from richer to poorer nations and from urban to rural areas. Relying on data on queries to the search engine Google between December 2018 and July 2021, this study looks at the evolution of demand for in-person versus digital international transfer services and evaluates if take-up rates of different types of service providers trace the initial drop and subsequent rebound of remittances. The recovery of remittances was accompanied by a modest and temporary increase in the interest in digital mechanisms for sending money to home countries, which is accompanied by lower demand for brick-and-mortar service providers.

Full text
Abstract:
This study is a first contribution to prioritization across productivity determinant capabilities that attempts to obtain the equivalent of a "shadow price" for each of these capabilities by estimating their impact on the success a country may have in reaching higher income per capita groups. The prioritization of these determinants-spanning different sectors-seems to be specific to the income per capita group to which a country belongs. Moreover, empirical estimates reveal that interactions among sectors matter for increasing the probability of climbing up the income-per-capita ladder, reflecting the existence of complementarities across sectors, thus indicating that the joint improvement of some of them may be necessary before effects are noticeable. Results also indicate that the identification of priorities by looking at the impact that sectors have on increasing the likelihood of advancing to a better income per capita group may or may not coincide with the size of sector gaps typically used for the determination of priorities, as larger gaps do not necessarily capture the relevance of sectoral restrictions and their interactions.

Full text
Abstract:
Electric vehicles (EVs) play a significant role in enhancing the sustainability of transportation systems. However, their widespread adoption is hindered by inadequate public charging infrastructure, particularly to support long-distance travel. Identifying optimal charging station locations in large transportation networks presents a well-known NP-hard combinatorial optimization problem, as the search space grows exponentially with the number of potential charging station locations. This report introduces a quantum search-based optimization algorithm designed to enhance the efficiency of solving this NP-hard problem for both corridors and transportation networks. By leveraging quantum parallelism, amplitude amplification, and quantum phase estimation as a subroutine, the optimal solution is identified with a quadratic improvement in complexity compared to classical exact methods, such as branch and bound. The detailed design and complexity of a resource-efficient quantum circuit are discussed.

Abstract:
The article studies the results of the research aimed at the improvement of the methodology of develop- ment of the health-preserving competence of a Physical Education teacher in conditions of post-graduate education on the basis of Nikolai Bernstein’s theory of movement construction using virtual reality technologies. Based on the use of AR/VR technologies a software application “Virtual Model Illustrating Nikolai Bernstein’s Theory of Movement Construction” was developed. The stated model is one of the tools of the “Methodology of development of the health preserving competence of a Physical Educa- tion teacher on the basis of Nikolai Bernstein’s theory of the levels of movement construction”. The experimental study determines that the application of the virtual model within the stated methodology is an effective tool for the development of the health preserving competence of a Physical Education teacher. The application of the virtual model allows the actualization of the health preserving, conceptual, gnoseological, biomechanical, inclusive, corrective potentials of Nikolai Bernstein’s theory of movement construction. The use of the virtual model presents the ways of targeted and meaningful use of Nikolai Bernstein’s theory of the levels of movement construction by a Physical Education teacher and the improvement of physical and recreational technologies and concrete physical exercises and movement modes. Due to the application of virtual reality tools, health-preserving, preventative, corrective and developmental strategies are being formed among which the significant ones are: “Application of syner- gistic movements to adaptation to movement activity, and recreation”, “Application of spatial movements for actualization of the orientation and search activities and development of spatial thinking”, “Use of movements with a complicated algorithm for intellect development”.

Abstract:
Under the Food Hygiene Rating Scheme (FHRS), places where food is supplied, sold or consumed are given a rating ranging from 0 to 5, with 5 indicating ‘very good’ food hygiene and 0 indicating ‘urgent improvement necessary’. In Northern Ireland and Wales, businesses are legally required to display their food hygiene rating sticker in a prominent place like the front door, entrance or window of the business. Businesses in England do not have to display their rating at their premises but are encouraged to do so. Across England, Northern Ireland and Wales, food hygiene ratings are also available to search on the FSA website. The Food Standards Agency (FSA) has conducted research into the Display of Food Hygiene Ratings in England, Northern Ireland and Wales since 2011, although the research was paused in 2020 due to COVID-19 pandemic. In 2021, the FSA commissioned IFF Research to update the research with the following aims: Provide a representative estimate of the display of food hygiene ratings by food businesses Explore the reasons and drivers for display and non-display Explore business awareness and attitudes towards the scheme Fieldwork in November and December 2021 comprised 1,522 covert audits of food businesses in England, Wales, and Northern Ireland and 1,500 telephone interviews of food businesses.

Abstract:
In this paper, an automated framework is presented to perform helicopter rotor blade planform optimization. This framework contains three elements, Dakota, ParBlade, and RCAS. These elements are integrated into an environment control tool, Galaxy Simulation Builder, which is used to carry out the optimization. The main objective of this work is to conduct rotor performance design optimizations for forward flight and hover. The blade design variables manipulated by ParBlade are twist, sweep, and anhedral. The multi-objective genetic algorithm method is used in this study to search for the optimum blade design; the optimization objective is to minimize the rotor power required. Following design parameter substitution, ParBlade generates the modified blade shape and updates the rotor blade properties in the RCAS script before running RCAS. After the RCAS simulations are complete, the desired performance metrics (objectives and constraints) are extracted and returned to the Dakota optimizer. Demonstrative optimization case studies were conducted using a UH-60A main rotor as the base case. Rotor power in hover and forward flight, at advance ratio 𝜇𝜇 = 0.3, are used as objective functions. The results of this study show improvement in rotor power of 6.13% and 8.52% in hover and an advance ratio of 0.3, respectively. This configuration also yields greater reductions in rotor power for high advance ratios, e.g., 12.42% reduction at 𝜇𝜇 = 0.4.

Abstract:
This report is a critical and systematic review of the literature on professional education accreditation models, associated methods, and the effectiveness and impact of each model. The review was conducted to inform a review and update of the Royal College of Veterinary Surgeons (RCVS) standards of accreditation for veterinary degrees. The purpose of the study was to rapidly appraise the evidence for the effectiveness, impact, and feasibility of different accreditation approaches, in order to inform best practices for the accreditation of professional education programs. The study focused on accreditation for programs which produce practice-ready graduates, including for veterinary programs. The authors searched several databases for articles published from 2000 to 2020, using search terms identified during a scoping phase, and applied a rapid review methodology in line with contextual, time, and resource requirements. The full-text review included 32 articles, from which a clear transition in the literature was seen from input- and process-based models (pre- and early 2000s) to outcomes-based models (in the 2000s and early 2010s). Continuous quality improvement and targeted models (including risk-based and thematic) represent more recent approaches in accreditation practice. However the review identified limited empirical evidence for the relative effectiveness of different accreditation approaches in professional education, although evidence for the more recent accreditation approaches is emerging.
