1. 21. Natural Language Processing Methods for Automatic Illustration of Text

   Författare :Richard Johansson; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural language processing; semantic analysis; automatic illustration;

   Sammanfattning : The thesis describes methods for automatic creation of illustrations of natural-language text. The main focus of the work is to convert texts that describe sequences of events in a physical world into animated images. This is what we call text-to-scene conversion. LÄS MER

3. 22. Semantic Spaces of Clinical Text : Leveraging Distributional Semantics for Natural Language Processing of Electronic Health Records

   Författare :Aron Henriksson; Hercules Dalianis; Martin Duneld; Jussi Karlgren; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; distributional semantics; random indexing; semantic space; electronic health records; clinical text; synonyms; diagnosis codes; adverse drug reactions; Computer and Systems Sciences; data- och systemvetenskap; IT for health; IT för hälsa; datorlingvistik; Computational Linguistics; datalogi; Computer Science;

   Sammanfattning : The large amounts of clinical data generated by electronic health record systems are an underutilized resource, which, if tapped, has enormous potential to improve health care. Since the majority of this data is in the form of unstructured text, which is challenging to analyze computationally, there is a need for sophisticated clinical language processing methods. LÄS MER

4. 23. Applications of Machine Learning on Natural Language Processing and Biomedical Data

   Författare :Dennis Medved; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : 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.

5. 24. Towards semantic language processing

   Författare :Anna Jonsson; Johanna Björklund; Marco Kuhlmann; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 25. Word Sense Embedded in Geometric Spaces - From Induction to Applications using Machine Learning

   Författare :Mikael Kågebäck; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
