1. 6. Transformation and Combination in Data-Driven Dependency Parcing

   Författare :Jens Nilsson; Joakim Nivre; Ryan McDonald; Växjö universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural Language Parsing; Dependency Parsing; Tree Transformation; Computer science; Datavetenskap; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

   Sammanfattning : This thesis deals with automatic syntactic analysis of natural languagetext, also known as parsing. The parsing approach is data-driven, whichmeans that parsers are constructed by means of machine learning, lookingat training data in the form of annotated natural language sentences. The syntactic framework used in the thesis is dependency-based. LÄS MER

3. 7. MaltParser -- An Architecture for Inductive Labeled Dependency Parsing

   Författare :Johan Hall; Joakim Nivre; Welf Löwe; Martin Volk; Växjö universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependency Parsing; Support Vector Machines; Machine Learning; Language technology; Språkteknologi; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

   Sammanfattning : This licentiate thesis presents a software architecture for inductive labeled dependency parsing of unrestricted natural language text, which achieves a strict modularization of parsing algorithm, feature model and learning method such that these parameters can be varied independently. The architecture is based on the theoretical framework of inductive dependency parsing by Nivre \citeyear{nivre06c} and has been realized in MaltParser, a system that supports several parsing algorithms and learning methods, for which complex feature models can be defined in a special description language.

4. 8. Linguistically Informed Neural Dependency Parsing for Typologically Diverse Languages

   Författare :Miryam de Lhoneux; Joakim Nivre; Sara Stymne; Emily Bender; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Dependency parsing; multilingual NLP; Universal Dependencies; Linguistically informed NLP; Computational Linguistics; Datorlingvistik;

   Sammanfattning : This thesis presents several studies in neural dependency parsing for typologically diverse languages, using treebanks from Universal Dependencies (UD). The focus is on informing models with linguistic knowledge. LÄS MER

5. 9. Transition-Based Natural Language Parsing with Dependency and Constituency Representations

   Författare :Johan Hall; Joakim Nivre; Welf Löwe; Sandra Kübler; Växjö universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural Language Parsing; Syntactic Parsing; Dependency Structure; Phrase Structure; Machine Learning; Computer science; Datavetenskap; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

   Sammanfattning : Denna doktorsavhandling undersöker olika aspekter av automatisk syntaktisk analys av texter på naturligt språk. En parser eller syntaktisk analysator, som vi definierar den i denna avhandling, har till uppgift att skapa en syntaktisk analys för varje mening i en text på naturligt språk. LÄS MER

7. 10. Contributions to Semantic Dependency Parsing : Search, Learning, and Application

   Författare :Robin Kurtz; Marco Kuhlmann; Lilja Øvrelid; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Semantic dependency parsing is the task of mapping natural language sentences into representations of their meaning in the form of directed graphs on words. These bilexical graphs are designed to capture the sentence-internal predicate-argument relationships – they tell us “who did what to whom” in the given sentence. LÄS MER
