With new regulations for mandatory sustainability reporting in Sweden, comprehensive and complete guidelines for corporations to follow are insufficient and the reports tend to be extensive.

Current technologies involve robotic programs that fills in values in templates and website listeners that notifies the editors when changes are made so that the editor can read up on the source change at the actual website. Editors can provide news faster and better if directly provided with abstracts of the external sources. This study applies deep learning algorithms to automatically formulate abstracts and tag sources with appropriate tags based on the context. The study

Abstract:

Searching the Internet for recipes to find interesting ideas for meals to prepare is getting increasingly popular. It can however be difficult to find a recipe for a dish that can be prepared with the items someone has available at home. In this thesis a solution to a part of that problem will be presented. This thesis will investigate a method for extracting the various parts of a recipe from the Internet in order to save them and build a searchable database of recipes where users can search for recipes based on the ingredients they have available. The system works for both English and Swedis

Abstract:

Summarization is the process of creating a more compact textual representation of a document or a collection of documents. In view of the vast increase in electronically available information sources in the last decade, filters such as automatically generated summaries are becoming ever more important to facilitate the efficient acquisition and use of required information. Different methods using natural language processing (NLP) techniques are being used to this end. One of the shallowest approaches is the clustering of available documents and the representation of the resulting clusters by o

Abstract:

With the rise in computational power, the prospect of simulating a complex engineering system with a high degree of accuracy and in a meaningful way is becoming a real possibility. Modelling and simulation have become ubiquitous throughout the engineering life cycle, as a consequence there are many thousands of existing models and simulations that are potential candidates for integration. This work is concerned with ascertaining if systems engineering principles are of use in the support of virtual testing, from desire to test, designing experiments, specifying simulations, selecting models an

Abstract:

Identifying semantic relations in natural language text is an important component of many knowledge extraction systems. This thesis studies the task of hypernym discovery, i.e discovering terms that are related by the hypernymy (is-a) relation. Speciﬁcally, this thesis explores how state-of-the-art methods for hypernym discovery perform when applied in speciﬁc language domains. In recent times, state-of-the-art methods for hypernym discovery are mostly made up by supervised machine learning models that leverage distributional word representations such as word embeddings. These models require l

Cette thèse explore diverses méthodes avancées en traitement du langage naturel (TAL) pour améliorer l'interprétation et l'analyse des données textuelles, en particulier dans les dialogues multilingues et techniques. La recherche se concentre sur plusieurs tâches clés du TAL, notamment l'extraction de mots-clés, la modélisation d'arbres syntaxiques, les systèmes de question-réponse techniques, la résolution de cataphore et l'exploitation des données spécifiques à un domaine.Une partie du travail présente de nouvelles approches utilisant des graphes de mots (GoW) et des arbres syntaxiques pour

Abstract:

How is information organized in the brain during natural reading? Where and when do the required processes occur, such as the perception of individual words and the construction of sentence meanings. How are semantics, syntax and higher-level narrative structure represented? Answering these questions is core to understanding how the brain processes language and organizes complex information. However, due to the complexity of language processing, most brain imaging studies focus only on one of these questions using highly controlled stimuli which may not generalize beyond the experimental setti

Abstract:

Voice commands are used in today's society to offer services like putting events into a calendar, tell you about the weather and to control the lights at home. This project tries to extend the possibilities of voice commands by improving an earlier proof of concept system that interprets intention given in natural language to program code. This improvement was made by mixing linguistic methods and neural networks to increase accuracy and flexibility of the interpretation of input. A user testing phase was made to conclude if the improvement would attract users to the interface. The results sho

Abstract:

The growth rate in the amount of biomedical documents is staggering. Unlocking information trapped in these documents can enable researchers and practitioners to operate confidently in the information world. Biomedical Named Entity Recognition (NER), the task of recognising biomedical names, is usually employed as the first step of the NLP pipeline. Standard NER models, based on sequence tagging technique, are good at recognising short entity mentions in the generic domain. However, there are several open challenges of applying these models to recognise biomedical names: ● Biomedical names
