Full textAbstract:
The California State University, Northridge (CSUN) Oviatt Library was the first library in the world to integrate an automated storage and retrieval system (AS/RS) into its operations. The AS/RS continues to provide efficient space management for the library. However, added value has been identified in materials security and inventory as well as customer service. The concept of library as space, paired with improved services and efficiencies, has resulted in the AS/RS becoming a critical component of library operations and future strategy. Staffing, service, and security opportunities paired with support and maintenance challenges, enable the library to provide a unique critique and assessment of an AS/RS.

Full textAbstract:
Nowadays, different types of content in different languages are available on World Wide Web and their usage is increasing rapidly. Cross Language Information Retrieval (CLIR) deals with retrieval of documents in another language than the language of the requested query. Various researchers worked on Cross Language Information Retrieval systems for Indian languages using different translation approaches. There is still CLIR system to be developed which allow user to retrieve Marathi documents when English query is given. In the proposed English to Marathi Cross Language Information Retrieval system, translation is based on query translation approach. The proposed system retrieves Marathi documents depending on matching terms in query. The performance of the proposed system is improved by query pre-processing and query expansion using WordNet.

Full textAbstract:
A large horticultural database and an electronic retrieval system for extension education programs were developed using compact disk-read only memory (CD-ROM) and World Wide Web (WWW) as the medium for information delivery. Object-oriented database techniques were used to organize the information. Conventional retrieval techniques including hypertext, full text searching, and expert systems were integrated into a complete package for accessing information stored in the database. A multimedia user interface was developed to provide a variety of capabilities including computer graphics and high resolution digitized images. Information for the CD-ROM was gathered from extension publications that were tagged using the standard generalized markup language (SGML)-based document markup language (International Standards Organization, 1986). Combining funds from the state legislator with grants from the USDA and other institutions, the CD-ROM system has been implemented in all 67 county extension offices in Florida and is available to the public as a for-sale CD-ROM. Public access is also available to most of the database through the WWW.

Full textAbstract:
With the increasing popularity and social influence of information retrieval (IR) systems, various studies have raised concerns on the presence of bias in IR and the social responsibilities of IR systems. Techniques for addressing these issues can be classified into pre-processing , in-processing and post-processing. Pre-processing reduces bias in the data that is fed into machine learning models. In-processing encodes fairness constraints as a part of the objective function or learning process. Post-processing operates as a top layer over the trained model to reduce the presentation bias exposed to users. This dissertation explored ways to bring the pre-processing and post-processing approaches, together with the fairness-aware evaluation metrics, into a unified framework as an attempt to break the vicious cycle of bias and improve fairness in IR. We first investigated the existing bias presented in search engine results. Specifically, we focused on the top-k fairness ranking in terms of statistical parity fairness and disparate impact fairness definitions. With Google search and a general purposed text cluster as a lens, we explored several topical diversity fairness ranking strategies to understand the relationship between relevance and fairness in search results. Our experimental results showed that different fairness ranking strategies resulted in distinct utility scores and performed differently with distinct datasets. Second, to further investigate the relationship of data and fairness algorithms, we developed a statistical framework that was able to facilitate various analysis and decision making. Our framework could effectively and efficiently estimate the domain of data and solution space. We derived theoretical expressions to identify the fairness and relevance bounds for data of different distributions, and applied them to both synthetic datasets and real world datasets. We presented a series of use cases to demonstrate how our framework was applied to associate data and provide insights to fairness optimization problems. Third, we proposed an evaluation metric FAIR for the ranking results that encoded fairness, diversity, novelty and relevance. This metric offered a new perspective of evaluating fairness-aware ranking results. Based on this metric, we developed an effective ranking algorithm that jointly optimized for fairness and utility. Our experiments showed that our new metric was able to highlight results that achieved good user utility and fair information exposure at the same time. We showed how FAIR metric related to existing metrics through correlation analysis and case studies, and demonstrated the effectiveness of our FAIR-based algorithm.

Full textAbstract:
This article looks at the access to geographic information through a review of information science theory and its application to the WWW. The two most common retrieval systems are information and data retrieval. A retrieval system has seven elements: retrieval models, indexing, match and retrieval, relevance, order, query languages and query specification. The goal of information retrieval is to match the user's needs to the information that is in the system. Retrieval of geographic information is a combination of both information and data retrieval. Aids to effective retrieval of geographic information are: query languages that employ icons and natural language, automatic indexing of geographic information, and standardization of geographic information. One area that has seen an explosion of geographic information retrieval systems (GIR's) is the World Wide Web (WWW). The final section of this article discusses how seven WWW GIR's solve the the problem of matching the user's information needs to the information in the system.

Full textAbstract:
We propose a new concept of intelligent support systems for topic-based information retrieval. As information retrieval (IR) on the World Wide Web (WWW) becomes widespread, new types of tools and systems that do not only find specific pages the user wants, but also and helping the user learn about a particular field of interest are increasingly needed. Two systems based on this consideration are introduced in this paper. One is the Fish View system for supporting document-ordering. It focuses on the user’s document-ordering (making diagrams) while reading, and the user’s viewpoint is represented by a combination of a small number of concepts taken from the existing concept structure dictionary. The extracted viewpoint can be used for measuring the similarity among documents, using fisheye matching, the extended Vector Space Model. The other is the query network for visualization of the topic distribution through WWW IR, and its concept employing the Immune Network model is introduced with preliminary experiments.

Full textAbstract:
Cross language information retrieval (CLIR) is a retrieval process in which the user fires queries in one language to retrieve information from another (different) language. The diversity of information and language barriers are the serious issues for communication and cultural exchange across the world. To solve such barriers, Cross language information retrieval system, are nowadays in strong demand. CLIR is a subset of Information Retrieval (IR) system. Information Retrieval deals with finding useful information from a large collection of unstructured, structured and semi-structured data to a user query where the query is a set of keywords. Information Retrieval can be classified into different classes such as Monolingual information retrieval, Bi-Lingual Information Retrieval, Multilingual information retrieval and Cross language information retrieval. This paper focuses on the various IR variants and techniques used in CLIR system. Further, based on available literature, a number of challenges and issues in CLIR have been identified and discussed. It gives an overview of the advantages, limitations, tools available in CLIR research. It also describes new application areas of CLIR such as medical, multimedia, question answering system etc. The need for exploring and building more specialized information system that enable speakers of an Odia language to discover valuable information beyond linguistic and cultural barriers. This study is aimed at building an experimental CLIR system between one of the under-resourced language (i.e. Odia) and one of the most commonly used online language (i.e. English) in future.

AbstractIt is generally observed throughout the world that in the last two decades, while the average speed of computers has almost doubled in a span of around eighteen months, the average speed of the network has doubled merely in a span of just eight months!. In order to improve the performance, more and more researchers are focusing their research in the field of computers and its related technologies. World Wide Web (WWW) acts as a medium for sharing of information. As a result, millions of applications run on the Internet and cause increased network traffic and put a great demand on the available network infrastructure. The slow retrieval of Web pages may reduce the user interest from accessing them. To deal with this problem Web caching and Web pre-fetching are used. This paper focuses on a methodology for improving the proxy-based Web caching system using Web mining. It integrates Web caching and Pre-fetching through an efficient clustering based pre-fetching technique.

Now in the world a problem of reliable information retrieval in the Internet network is especially critical. It is defined by increased data capacity and by the absence of control over data placement. It is offered to determine information reliability by methods of fuzzy logic at the correct formation of retrieval request. For the estimate of completeness, truth and integrity of data obtained it is offered to rely upon the analysis of information from other pages of a site found. In accordance with this the notions of topical closeness of site pages and reliability of information presented in the remaining sections. To organize an output are compiled the rules for the integral reliability output of a site page. For example, if information on a page does not coincide with analyzed one and is reliable then one can suppose that related information is reliable. Further, with the use of Mam-dani controller is carried out a defuzzification. A technology for a retrieval request organization is offered to increase an information content retrieval. The technologies offered for retrieval and analysis of information allow increasing effectiveness and a retrieval rate of reliable, integrated and true information in the Internet network.

Geographical Information System (GIS) is computer software used for collection, storage, transformation, retrieval and display of geo spatial data from the real GIS world. The geographical data represent the real world in terms of their position with respect to a known coordinate system, their attributes and their geographical relationship with other objects. GIS utilization is being recognized as having the potential to improve the health of that specific population. GIS contributes in policy making, monitoring, implementation, and research in health sector. Need of population according to information provided by the GIS can be determined, which gives a quick and comprehensive review of regional and geographical health problems so that policy makers can utilize this for policy making and for forecasting the epidemics and other community health problems by using GIS. GIS system is a powerful and effective tool for creating intelligent/guide maps for, e.g., location of local health facilities, trauma centers, and specialized hospitals. It’s easy to purchase the GIS (hardware and software), but its proper utilization is a big task for the organizations to achieve their specific goals.

This thesis describes WebDoc, an automated system that classifies Web documents according to the Library of Congress classification system. This work is an extension of an early version of the system that successfully generated indexes for journal articles. The unique features of Web documents, as well as how they will affect the design of a classification system, are discussed. We argue that full-text analysis of Web documents is inevitable, and contextual information must be used to assist the classification. The architecture of the WebDoc system is presented. We performed experiments on it with and without the assistance of contextual information. The results show that contextual information improved the system?s performance significantly.

Full textAbstract:
[Truncated abstract] Rumours can lead to unpredictable events: the manner in which an organisation responds to a commercial rumour can alter its reputation, and can affect its profitability as well as, ultimately, its survival. Commercial rumours are now a prominent feature of the business environment. They can emerge from organisational change, pending workforce layoffs, mergers, and changes to management, in addition, commercial rumours can lower morale and undermine productivity. There are several well-known examples of commercial rumours that have been, or continue to be, circulated. Commercial rumours are typically either about a conspiracy or contamination issue. Conspiracy rumours usually target those organisational practices or policies which are identified as undesirable by the stakeholders. This form of rumour is often precipitated by situations where people do not have all the information about a situation, for example the rumour about Proctor & Gamble being run by the Moonies. Snapple, the soft drink company, was rumoured in 1992 to be supporting the Ku Klux Klan in closing abortion clinics. Contamination rumours are wide-ranging and typically have revulsion theme, such as McDonald’s "worms in the burger", Pop Rock’s candies which exploded in the stomach, and poison in Herron’s paracetamol . . . Marketers suggest that web sites Commerical Rumour Responses on the Web represent the future of marketing communications on the Internet. The key implication of this study for organisations is when faced with a negative rumour, specific and selected Web pages can be used manage company’s stakeholders recall the rumour and organisational stakeholders can be persuaded by the company’s rumour response strategies.

Resumo: A crescente quantidade de imagens geradas e disponibilizadas atualmente tem eito aumentar a necessidade de criação de sistemas de busca para este tipo de informação. Um método promissor para a realização da busca de imagens e a busca por conteúdo. Este tipo de abordagem considera o conteúdo visual das imagens, como cor, textura e forma de objetos, para indexação e recuperação. A busca de imagens por conteúdo tem como componente principal o descritor de imagens. O descritor de imagens é responsável por extrair propriedades visuais das imagens e armazená-las em vetores de características. Dados dois vetores de características, o descritor compara-os e retorna um valor de distancia. Este valor quantifica a diferença entre as imagens representadas pelos vetores. Em um sistema de busca de imagens por conteúdo, a distancia calculada pelo descritor de imagens é usada para ordenar as imagens da base em relação a uma determinada imagem de consulta. Esta dissertação realiza um estudo comparativo de descritores de imagens considerando a Web como cenário de uso. Este cenário apresenta uma quantidade muito grande de imagens e de conteúdo bastante heterogêneo. O estudo comparativo realizado nesta dissertação é feito em duas abordagens. A primeira delas considera a complexidade assinto tica dos algoritmos de extração de vetores de características e das funções de distancia dos descritores, os tamanhos dos vetores de características gerados pelos descritores e o ambiente no qual cada descritor foi validado originalmente. A segunda abordagem compara os descritores em experimentos práticos em quatro bases de imagens diferentes. Os descritores são avaliados segundo tempo de extração, tempo para cálculos de distancia, requisitos de armazenamento e eficácia. São comparados descritores de cor, textura e forma. Os experimentos são realizados com cada tipo de descritor independentemente e, baseado nestes resultados, um conjunto de descritores é avaliado em uma base com mais de 230 mil imagens heterogêneas, que reflete o conteúdo encontrado na Web. A avaliação de eficácia dos descritores na base de imagens heterogêneas é realizada por meio de experimentos com usuários reais. Esta dissertação também apresenta uma ferramenta para a realização automatizada de testes comparativos entre descritores de imagens.
Abstract: The growth in size of image collections and the worldwide availability of these collections has increased the demand for image retrieval systems. A promising approach to address this demand is to retrieve images based on image content (Content-Based Image Retrieval). This approach considers the image visual properties, like color, texture and shape of objects, for indexing and retrieval. The main component of a content-based image retrieval system is the image descriptor. The image descriptor is responsible for encoding image properties into feature vectors. Given two feature vectors, the descriptor compares them and computes a distance value. This value quantifies the difference between the images represented by their vectors. In a content-based image retrieval system, these distance values are used to rank database images with respect to their distance to a given query image. This dissertation presents a comparative study of image descriptors considering the Web as the environment of use. This environment presents a huge amount of images with heterogeneous content. The comparative study was conducted by taking into account two approaches. The first approach considers the asymptotic complexity of feature vectors extraction algorithms and distance functions, the size of the feature vectors generated by the descriptors and the environment where each descriptor was validated. The second approach compares the descriptors in practical experiments using four different image databases. The evaluation considers the time required for features extraction, the time for computing distance values, the storage requirements and the effectiveness of each descriptor. Color, texture, and shape descriptors were compared. The experiments were performed with each kind of descriptor independently and, based on these results, a set of descriptors was evaluated in an image database containing more than 230 thousand heterogeneous images, reflecting the content existent in the Web. The evaluation of descriptors effectiveness in the heterogeneous database was made by experiments using real users. This dissertation also presents a tool for executing experiments aiming to evaluate image descriptors.

Full textAbstract:
M.Inf.Users of geographic information systems (GIS) are often faced with a challenge with regard to identification, location and overall access to digital data used in the application of GIS. The selection of the appropriate data from the large volumes available, also gaining access to available data and the establishment of the distribution of data from one central source are necessary tasks in order to improve the dissemination of GIS data. However, these are difficult tasks due to many users being unaware of the full range of available digital GIS data. A mechanism that could assist in improving access to digital GIS data is the Webbased GIS clearinghouse. This study was initiated to determine the requirements of GIS clearinghouses for optimum accessibility to digital GIS data. A literature study was conducted to investigate the nature of data that is used in GIS clearinghouses, the current trends in GIS data on the Web and the unique characteristics of the Web that can increase accessibility to digital GIS data. A selection of clearinghouses was made and these were evaluated in order to determine variables that can be translated into criteria from which a model for the evaluation of GIS clearinghouses could be established. This model can act as a working document or check-list for users to evaluate GIS clearinghouses, or for designers to create new or improve existing GIS clearinghouses.

As the World Wide Web continues to grow, people clearly want to do much more
with it than just publish static pages of text and graphics. While such increased interactivity
has traditionally been accomplished through the use of server-side CGI scripts,
much recent research on Web browsers has been on extending their capabilities through
the addition of various types of client-side services. The most popular of these extensions
take the form of plug-ins, applets, and "document scripts" such as Java Script. However,
because these extensions have been created in a haphazard way by a variety of independent
groups, they suffer greatly in terms of flexibility, uniformity, and interoperability. Interactive
HTML is a system that addresses these problems by combining plug-ins, applets,
and document scripts into one uniform and cohesive architecture. It is implemented as an
external C library that can be used by a browser programmer to add client-side services to
the browser. The IHTML services are implemented as dynamically loaded "language modules,"
allowing new plug-ins and language interpreters to be added to an iHTML browser
without recompiling the browser itself. The system is currently integrated with NCSA's
X Mosaic browser and includes language modules for a text viewer plug-in and Python
language interpreter. This thesis examines the iHTML architecture in the context of the
historical development of Web client-side services and presents an example of iHTML's
use to collect usage information about Web documents.Graduation date: 1997

Full textAbstract:
Although much effort has been invested to build applications that support group
work, collaborative applications have not found easy success. The cost of adopting and
maintaining collaborative applications has prevented their widespread use, especially
among small distributed groups. Application developers have had difficulties recognizing
the extra effort required by groups to use collaborative applications and how to either
reduce this effort or provide other benefits to compensate for the extra work. These
problems have limited the success of collaborative applications, which have not attained
the same level of productivity improvements that single user applications have achieved. In
this thesis we present a framework that describes the types of computer support that can
facilitate the work of distributed engineering design groups. Our framework addresses
support for web-based groups in particular because we believe the web can be a powerful
medium for collaboration if accommodated properly. We show how the concepts in this
framework can be implemented by prototyping a web-based engineering decision support
system. Our framework is a synthesis of ideas motivated by an examination of literature in
various fields that share a common interest in collaborative work. It can influence
application development by helping developers become aware of the types of support
should be considered to aid web-based collaborative design.Graduation date: 1997

Although there is research into student learning on the Web and other computer-supported environments, there has been little investigation into the practice and pedagogy of university Web teachers. This qualitative study used a series of interviews of eight higher education faculty to gather data on their Web teaching practices, and an examination of their Web courses to identify their pedagogies.
There was a notable difference in the way the four teachers with Web-assisted courses and the four teachers with Web-only courses used the Web in their teaching. Those with Web-assisted courses used the Web primarily as a connection to expanded resources and a supplement to their face-to-face teaching. Those who taught Web-only courses used the Web for resource access, and also used asynchronous dialogue and peer interactions to support student construction of knowledge. Moreover, the
Web-only teachers reported a shift in their roles from lecturer and expert
in the classroom to facilitator and co-learner as Web teachers.
Four aspects of the Web teaching environment appear to be foundational in supporting an effective Web pedagogy: (1) the varied and extensive uses of e-mail, (2) the "think time" made possible by asynchronous dialogue, (3) distributed, hyperlinked learning, and (4) a reported shift from a content focus to process and issues because Web instructors are confident that the material is presented in the Web course as they wish it. The experiences of the Web teachers in the study would indicate that these four elements can be leveraged to improve university Web teaching and deepen student learning, perhaps even beyond results capable of achievement in face-to-face teaching.Graduation date: 1999

Full textAbstract:
The Internet and world wide web (WWW) have in recent years, grown exponentially in size and in terms of the volume of information that is available on it. In order to effectively deal with the huge amount of information on the web, so called web search engines have been developed for the task of retrieving useful and relevant information for its users. Unfortunately, these web search engines have not kept pace with the boom growth and commercialization of the web. The main goal of this dissertation is the development of a model for a collaborative personalized meta-search agent (COPEMSA) system for the WWW. This model will enable the personalization of web search for users. Furthermore, the model aims to leverage on current search engines on the web as well as enable collaboration between users of the search system for the purposes of sharing useful resources between them. The model also employs the use of multiple intelligent agents and web content mining techniques. This enables the model to autonomously retrieve useful information for it’s user(s) and present this information in an effective manner. In order to achieve the above stated, the COPEMSA model employs the use of multiple intelligent agents. COPEMSA consists of five core components: a user agent, a query agent, a community agent, a content mining agent and a directed web spider. The user agent learns about the user in order to introduce personal preference into user queries. The query agent is a scaled down meta-search engine with the task of submitting the personalized queries it receives from the user agent to multiple search services on theWWW. The community agent enables the search system to communicate and leverage on the search experiences of a community of searchers. The content mining agent is responsible for analysis of the retrieved results from theWWWand the presentation of these results to the system user. Finally, a directed web spider is used by the content mining agent to retrieve the actual web pages it analyzes from the WWW. In this dissertation an additional model is also presented to deal with a specific problem all web spidering software must deal with namely content and link encapsulation.Prof. E.M. Ehlers

Since its introduction in the early 1990s, the quick growth of the World Wide Web
(WWW) traffic raises the question of whether past Local Area Network (LAN) packet
traces still reflect the current situation or whether they have become obsolete. For this
thesis, several LAN packet traces were obtained by monitoring the LAN of a typical academic
environment. The tools for monitoring the network were a stand-alone HP LAN
Protocol Analyzer as well as the free-ware software tool tcpdump. The main focus was
placed on acquiring a low-level overview of the LAN traffic. Thus, it was possible to
determine what protocols were mainly used and how the packet sizes were distributed.
In particular, this study aimed at establishing the amount of WWW traffic on the LAN,
and determining the MIME-Types of this traffic. The results indicate that in a typical
academic environment, conventional sources of LAN traffic such as NFS are still predominant,
whereas WWW traffic plays a rather marginal role. Furthermore, a large portion
of the network packets contains little or no data at all, while another significant portion
of the packets have sizes around the Maximum Transfer Unit (MTU). Consequently,
research in the networking field has to direct its focus on issues beside the
WWW.Graduation date: 1998

Since the 19th century, the world has witnessed an exponential growth in the number and variety of information products, sources, and services. This development has resulted in technological innovations for faster and more efficient processing and storage of information, as individuals and organisations strive to keep up with increasing demands. The value of information organisation cannot be overemphasized. The volume of information generated, transmitted and stored is of such immense proportion that without adequate organisation, the retrieval process would be cumbersome and frustrating. This chapter will highlight and describe the roles of an information retrieval system and the context of information organisation in several institutions. It will also discuss the various information retrieval tools and the different models used in information retrieval process. The ultimate goal of this chapter is to enable students, practicing librarians, and others interested in information services to understand the concepts, principles, and tools behind information organisation and retrieval. The conclusion of the chapter will emphasize the need for continuous evaluation of these principles and tools for sustained improvement.

In the last decade, a new paradigm had seen the light named Cloud Computing, which allows the delocalization of data and applications on a dematerialized infrastructure accessible from Internet. Unfortunately, the cloud services are facing many drawbacks especially in terms of security and data confidentiality. However, in a world where digital information is everywhere, finding the desired information has become a crucial problem. For the purpose to preserve the user privacy life new approaches and ideas had been published. The content of this chapter is a new system of bio-inspired private information retrieval (BI-PIR) using the lifestyle of social bees, which allows both to find and hid, the sensitive desired information. It is based on a multi-filters cryptosystem used by the server for the encryption of stored document and the retrieval model using a combination of filters by 3 types of workers bees (Purveyor, guardian and cleaner), the queen bee represents the query, and the hive represents the class of relevant documents. We have tested this system on the benchmark MEDLINE dataset with panoply of validation tools (recall, precision, f-measure, entropy, silence, noise, and accuracy) and a comparative study had been realized with other systems existed in literature. Finally, a 3D visualization tool had been developed in order to make the results in graphical format understandable by humans. Our objectives is to improve the services quality of cloud computing.

In today's competitive world, each company is required to change software to meet changing customer requirements. At the same time, an efficient information retrieval system is required as changes made to software in different versions can lead to complicated retrieval systems. This research aims to find the association between changes and object-oriented metrics using different versions of open source software. Earlier researchers have used various techniques such as statistical methods for the prediction of change-prone classes. This research uses execution time, frequency, run time information, popularity, and class dependency in prediction of change-prone classes. For evaluating the performance of the prediction model, sensitivity, specificity, and ROC curve are used. Higher values of AUC indicate the prediction model gives accurate results. Results are validated in two phases: Experimental Analysis I validates results using OpenClinic software and OpenHospital software and Experimental Analysis II validates result using Neuroph 2.9.2 and Neuroph 2.6.

Software agents controlling production devices must maintain an up-to-date view of the physical world state in order to efficiently reason and plan their actions. Especially in a factory automation system, the world state undergoes rapid evolution. To enable accurate decision-making, the world view must constantly be synchronized with the changes. This paper discusses two approaches to updating the world view based on event notifications sent by web services representing production devices in a manufacturing system. One approach requires that a set of update rules is separately specified, whereas the other involves automatically deriving the update rules from the semantic web service descriptions. While this paper specifically focuses on the factory automation domain, both of the approaches presented are applicable to other domains as well. The main assumptions are that the domain is composed of world-altering web services, which provide adequate service interfaces to detect changes in their state, and that all relevant changes in the overall domain state can be directly derived from the service state changes.

It is generally observed throughout the world that in the last two decades, while the average speed of computers has almost doubled in a span of around eighteen months, the average speed of the network has doubled merely in a span of just eight months! In order to improve the performance, more and more researchers are focusing their research in the field of computers and its related technologies. Internet is one such technology that plays a major role in simplifying the information sharing and retrieval. World Wide Web (WWW) is one such service provided by the Internet. It acts as a medium for sharing of information. As a result, millions of applications run on the Internet and cause increased network traffic and put a great demand on the available network infrastructure.

In a world of virtualization, where we are having a larger source of images and descriptions available to modern world and based on their requirement it has been utilized from stored information, data center or cloud to larger audience, but at same time rising number of images requires good tools to store the data and retrieve data. Along with this there is a major importance of Quick search and retrieval tools for these growing images to retrieve information quickly and accurately. High demand for automated or computer assisted classification, query and retrieval methods is required to access huge image databases because such method will try to overcome the drawback of higher cost of manual classification and retrieval of relevant image. Scope as researchers to develop automated methods in image features for indexing and retrieval of images related to texture, feature and color is in demand.

Analogy-making has been deemed one of the core cognitive mechanisms which play a role in human creative thinking activities such as design and art. Designers can make use of analogies in various stages of design including ideation, planning and evaluation. However, human analogy-making is limited by experience and reliance of human memory on superficial attributes rather than relational or causal structure during analogy retrieval. In this regard, different design-by-analogy tools have been developed to assist designers in analogical reasoning. Analogical reasoning tools can be viewed as either based on hand-coded structured knowledge or natural-language-based design-by-analogy tools. The former are naturally limited in extent and scope to that which was hand coded [1]. Alternatively, natural language analogical reasoning can leverage the abundantly available textual resources. Current text-based analogy research for design have relied on analogies between individual word meanings. This leaves open consideration of the relational structure of the language where the relational similarity of texts can indicate a significant analogy. In this article, we develop four computational models of analogy that capture relational structure of the text. This includes spatial representation of semantics, multi-level deep neural reasoning, graph matching based model and transformation-based model. The models are then combined together into an ensemble model to achieve acceptable level of analogical accuracy for the end-user. The underlying design-related knowledge upon which analogies were drawn includes engineering ontologies, function hierarchy and raw patent texts. Instantiating this analogical reasoning model in design concept analogy retrieval system, we show this approach can help retrieve meaningful analogies from the World Intellectual Property Organization (WIPO) patent repository. We demonstrate this for a particular design problem.

With people becoming more individualistic in their choices they make in personalizing the goods and services they use, as resulted in major development that has been recorded in the customisation world. This individualism has resulted in the increase in demand of customized products in many industries especially in the footwear, kitchen and computer industries. However, little has been done when it comes to mechanically oriented products and little flexibility has been given to the consumers in the co-creation of customized products. The Hybrid system of classification is one way to satisfy the customers’ need for the products that are mechanically oriented in nature thereby meeting their desire needs. This paper presents a framework in which an Hybrid system of classification is used to integrates Customers into the design process by defining, configuring, matching, or modifying personal product that is mechanically oriented in nature and grouping the products into classes and sub-classes using a wide range of product parameters, products configuration which make it possible to add and/or change functionalities of a core product, a coding system for mechanical designs which is applicable to each product in the hierarchy, the use of a database for the products information. And the retrieval system to retrieve a similar product code from the database if the initial customer configuration data does not yield a feasible product code through the application of Analytic Hierarchy Process and finally modifying the existing similar product to suit the customers desire.

This paper reports on a knowledge rich design repository system. Current design tools and methodologies are reviewed and used to identify necessary design knowledge to populate a design repository. Building on previous research, an operational design repository is reviewed. The design repository system demonstrated includes a single point of entry application for product information, a relational database for archiving design knowledge and web-based tools. Web services are used to support design knowledge retrieval through search, browse and real-time design tool generation. From the repository interface, design tools such as bills of materials and design structure and function component matrices are generated. The output design tools are tested in real world design applications and validated. The result is a useful tool — applicable to several phases of product design.

Abstract In this paper, we describe recent experimental results from an ongoing design knowledge capture and reuse project. In the past several years, an increasing amount of the design work in the ME210 design course at Stanford, in which teams work for 30 weeks on industrially-sponsored real-world projects, has been captured in electronic format. This design information consists of design notes, drawings, reports, slide presentations, emails, vendor references, and even, in some cases, summaries of phone conversations, meeting minutes, and the like. The large corpus of captured information from the period of 1994 to 1996 was made available to the teams working on projects during the 1996–1997 academic year. A variety of filing and indexing schemes were used to organize the past data and help the teams sift through it. Because the data was all made available over a web server, we were able to collect information on access to it. We have thus had a chance to learn from studying the usage of a large body of captured design knowledge. Results from our analysis suggest that there were significant under-utilization of design work of others: there was only 8% access to past works, vs. 92% to the current year’s; and, there was only 15% access to design project-specific information, vs. 85% on logistic resources information. Important lessons have guided our efforts to improve the effectiveness of that usage based on what we’ve learned. These lessons include: • Informal design information is more useful to a broader audience when it is contextualized. We have put in place a capture system that makes it possible for students to add context to any information that’s been captured, and also specific reward structure, encouraging engineers to store, contextualize, and reuse captured design information. Preliminary observations suggest that this is worth the investment for a project as a whole. • It is important to accommodate a heterogeneous computing environment, both for capture and reuse; to support multiple methods for finding information; and to provide a uniform, well-behaved way of displaying archived documents. • In explaining our observations of varying levels of success in design capture systems, we have identified some patterns of enquiry and retrieval usage that are analogous to the patterns seen in library usage. Thus we identify library science as a valuable source of knowledge that until now has been under used by the design community.
