1. 41. Selective inhibition of acetylcholinesterase 1 from disease-transmitting mosquitoes : design and development of new insecticides for vector control

   Författare :Cecilia Engdahl; Anna Linusson; Fredrik Ekström; Zoran Radić; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acetylcholinesterase; non-covalent inhibitor; vector control; insecticide; mosquito; vector-borne disease; high throughput screening; rational design; biokemi; Biochemistry; datorlingvistik; computational linguistics;

   Sammanfattning : Acetylcholinesterase (AChE) is an essential enzyme with an evolutionary conserved function: to terminate nerve signaling by rapid hydrolysis of the neurotransmitter acetylcholine. AChE is an important target for insecticides. LÄS MER

3. 42. Why the pond is not outside the frog? Grounding in contextual representations by neural language models

   Författare :Mehdi Ghanimifard; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational linguistics; Language grounding; Spatial language; Distributional semantics; Computer vision; Language modelling; Vision and language; Neural language model; Grounded language model;

   Sammanfattning : In this thesis, to build a multi-modal system for language generation and understanding, we study grounded neural language models. Literature in psychology informs us that spatial cognition involves different aspects of knowledge that include visual perception and human interaction with the world. LÄS MER

4. 43. Discourse in Statistical Machine Translation

   Författare :Christian Hardmeier; Joakim Nivre; Jörg Tiedemann; Marcello Federico; Lluís Màrquez; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistical machine translation; Discourse-level machine translation; Document decoding; Local search; Pronominal anaphora; Pronoun translation; Neural networks; Computational Linguistics; Datorlingvistik;

   Sammanfattning : This thesis addresses the technical and linguistic aspects of discourse-level processing in phrase-based statistical machine translation (SMT). Connected texts can have complex text-level linguistic dependencies across sentences that must be preserved in translation. However, the models and algorithms of SMT are pervaded by locality assumptions. LÄS MER

5. 44. 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

7. 45. 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
