2. 1. Knowledge predication : A semantic typology

   Author : Anna Sjöberg; Bernhard Wälchli; Maria Koptjevskaja-Tamm; Volker Gast; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; semantic typology; constructional typology; semantic maps; knowledge; epistemology; parallel texts; language sampling; token-based typology; cognitive semantics; Linguistics; lingvistik;

   Abstract : The present thesis is an investigation of the cross-linguistic expression of knowledge predication (‘He knows that it’s raining’, ‘she knows the boy’ etc.) Knowledge predication is investigated in parallel texts—specifically New Testament translations—in a genealogically and areally stratified variety sample of 83 languages.

4. 2. Multi-Document Summarization and Semantic Relatedness

   Author : Olof Mogren; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; semantic relatedness; multi-document summarization; semantic similarity; automatic summarization;

   Abstract : Automatic summarization is the process of presenting the contents of written documents in a short, comprehensive fashion. Many approaches have been proposed for this problem, some of which extract content from the input documents (extractive methods), and others that generate the language in the summary based on some representation of the document contents (abstractive methods).

5. 3. With or without context : Automatic text categorization using semantic kernels

   Author : Johan Eklund; Högskolan i Borås; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; automatic text categorization; subject classification; machine learning; computational linguistics; support vector machines; semantic kernels; term weighting; divergence from randomness; Library and Information Science; Biblioteks- och informationsvetenskap;

   Abstract : In this thesis text categorization is investigated in four dimensions of analysis: theoretically as well as empirically, and as a manual as well as a machine-based process. In the first four chapters we look at the theoretical foundation of subject classification of text documents, with a certain focus on classification as a procedure for organizing documents in libraries.

6. 4. Best Trees Extraction and Contextual Grammars for Language Processing

   Author : Anna Jonsson; Johanna Björklund; Frank Drewes; Hendrik Jan Hoogeboom; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Weighted tree automata; the N-best problem; efficient algorithms; semantic graph; abstract meaning representation; contextual graph grammars; hyperedge replacement; graph extensions;

   Abstract : In natural language processing, the syntax of a sentence refers to the words used in the sentence, their grammatical role, and their order. Semantics concerns the concepts represented by the words in the sentence and their relations, i.e., the meaning of the sentence. READ MORE

7. 5. Splitting rocks: Learning word sense representations from corpora and lexica

   Author : Luis Nieto Piña; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; language technology; natural language processing; distributional models; semantic representations; distributed representations; word senses; embeddings; word sense disambiguation; linguistic resources; corpus; lexicon; machine learning; neural networks;

   Abstract : The representation of written language semantics is a central problem of language technology and a crucial component of many natural language processing applications, from part-of-speech tagging to text summarization. These representations of linguistic units, such as words or sentences, allow computer applications that work with language to process and manipulate the meaning of text. READ MORE
