  1. 1. Inductive Dependency Parsing of Natural Language Text

    Författare :Joakim Nivre; Walter Daelemans; Växjö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; natural language parsing; dependency parsing; memory-based learning; treebank parsing; Systems engineering; Systemteknik; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

    Sammanfattning : This thesis investigates new methods for syntactic parsing of unrestricted natural language text under requirements of robustness and disambiguation. A parsing system is required to assign to every sentence in a text at least one analysis (robustness) and at most one analysis (disambiguation). LÄS MER

  2. 2. Complexities of Parsing in the Presence of Reordering

    Författare :Martin Berglund; Frank Drewes; Bruce Watson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parsing; membership problems; complexity theory; reordering; shuffle; mildly context-sensitive; formal languages; Computer Science; datalogi;

    Sammanfattning : The work presented in this thesis discusses various formalisms for representing the addition of order-controlling and order-relaxing mechanisms to existing formal language models. An immediate example is shuffle expressions, which can represent not only all regular languages (a regular expression is a shuffle expression), but also features additional operations that generate arbitrary interleavings of its argument strings.

  5. 5. 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
