2. 11. Argument Differentiation. Soft constraints and data-driven models

   Author : Lilja Øvrelid; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; syntactic arguments; parsing; lexical acquisition; animacy; Scandinavian syntax; soft constraints; data-driven models; machine learning;

   Abstract : The ability to distinguish between different types of arguments is central to syntactic analysis, whether studied from a theoretical or computational point of view. This thesis investigates the influence and interaction of linguistic properties of syntactic arguments in argument differentiation. READ MORE

4. 12. Predicting Linguistic Structure with Incomplete and Cross-Lingual Supervision

   Author : Oscar Täckström; Joakim Nivre; Jussi Karlgren; Ryan McDonald; Hal Daumé III; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; linguistic structure prediction; structured prediction; latent-variable model; semi-supervised learning; multilingual learning; cross-lingual learning; indirect supervision; partial supervision; ambiguous supervision; part-of-speech tagging; dependency parsing; named-entity recognition; sentiment analysis; Computational Linguistics; Datorlingvistik;

   Abstract : Contemporary approaches to natural language processing are predominantly based on statistical machine learning from large amounts of text, which has been manually annotated with the linguistic structure of interest. However, such complete supervision is currently only available for the world's major languages, in a limited number of domains and for a limited range of tasks.

5. 13. Multilingual Abstractions: Abstract Syntax Trees and Universal Dependencies

   Author : Kolachina Prasanth; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Grammatical Framework; Universal Dependencies; Natural Language Processing; multilinguality; abstract syntax trees; dependency trees; multilingual generation; multilingual parsers;

   Abstract : This thesis studies the connections between parsing friendly representations and interlingua grammars developed for multilingual language generation. Parsing friendly representations refer to dependency tree representations that can be used for robust, accurate and scalable analysis of natural language text. READ MORE

6. 14. NLP methods for improving user rating systems in crowdsourcing forums and speech recognition of less resourced languages

   Author : Yonas Demeke Woldemariam; Henrik Björklund; Suna Bensch; Anssi Yli-Jyra; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NLP-algorithms; speech-recognition; transfer-learning; syntax-semantics; computational linguistic model; Amharic-NLP; cloud-NLP architecture; question-answering; crowdsourcing; user-rating; less-resourced languages; Computer Science; datalogi;

   Abstract : We develop NLP and ASR methods (e.g. READ MORE

7. 15. Multilingual Grammars and Universal Dependencies

   Author : Kolachina Prasanth; Göteborgs universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NLP; Grammatical Framework; Universal Dependencies; Abstract Syntax; Grammatical Framework;

   Abstract : Abstract syntax trees are an alternative representation to syntactic structures commonly found in NLP systems. This representation allows for sharing of structures across languages, making it well suited to serve as a translation interlingua. READ MORE
