2. 21. Applications of Machine Learning on Natural Language Processing and Biomedical Data

   Author : Dennis Medved; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Machine learning is ubiquitous in today’s society, with promising applicationsin the field of natural language processing (NLP), so that computers can handlehuman language better, and within the medical community, with the promiseof better treatments. Machine learning can be seen as a subfield of artificialintelligence (AI), where AI is used to describe a machine that mimics cognitivefunctions that humans associate with other human minds, such as learning orproblem solving.

4. 22. Towards semantic language processing

   Author : Anna Jonsson; Johanna Björklund; Marco Kuhlmann; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Weighted tree automata; abstract meaning representation; contextual hyperedge replacement grammar; hyperedge replacement grammar; semantic modelling; the N best problem; Computer Science; datalogi; datorlingvistik; computational linguistics;

   Abstract : The overall goal of the field of natural language processing is to facilitate the communication between humans and computers, and to help humans with natural language problems such as translation. In this thesis, we focus on semantic language processing. READ MORE

5. 23. Word Sense Embedded in Geometric Spaces - From Induction to Applications using Machine Learning

   Author : Mikael Kågebäck; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; word sense induction; word sense disambiguation; word embeddings; extractive summarisation; neural networks; deep learning; natural language procsessing; reinforcement learning;

   Abstract : Words are not detached individuals but part of a beautiful interconnected web of related concepts, and to capture the full complexity of this web they need to be represented in a way that encapsulates all the semantic and syntactic facets of the language. Further, to enable computational processing they need to be expressed in a consistent manner so that similar properties are encoded in a similar way. READ MORE

6. 24. Analysing normative contracts : On the semantic gap between natural and formal languages

   Author : John J. Camilleri; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; contract analysis; controlled natural language; formal methods; timed automata; model checking;

   Abstract : Normative contracts are documents written in natural language, such as English or Swedish, which describe the permissions, obligations, and prohibitions of two or more parties over a set of actions, including descriptions of the penalties which must be payed when the main norms are violated. We encounter such texts frequently in our daily lives in the form of privacy policies, software licenses, and service agreements. READ MORE

7. 25. Complexity and expressiveness for formal structures in Natural Language Processing

   Author : Petter Ericson; Henrik Björklund; Frank Drewes; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; graph grammars; formal languages; natural language processing; parameterized complexity; abstract meaning representation; tree automata; deterministic tree-walking transducers; mildly context-sensitive languages; hyperedge replacement; tree adjoining languages; minimally adequate teacher;

   Abstract : The formalized and algorithmic study of human language within the field of Natural Language Processing (NLP) has motivated much theoretical work in the related field of formal languages, in particular the subfields of grammar and automata theory. Motivated and informed by NLP, the papers in this thesis explore the connections between expressibility – that is, the ability for a formal system to define complex sets of objects – and algorithmic complexity – that is, the varying amount of effort required to analyse and utilise such systems.
