  1. 1. Tree Transformations in Inductive Dependency Parsing

    Författare :Jens Nilsson; Joakim Nivre; Pierre Nugues; Växjö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inductive Dependency Parsing; Dependency Structure; Tree Transformation; Non-projectivity; Coordination; Verb Group; Language technology; Språkteknologi; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

    Sammanfattning : This licentiate thesis deals with automatic syntactic analysis, or parsing, of natural languages. A parser constructs the syntactic analysis, which it learns by looking at correctly analyzed sentences, known as training data. The general topic concerns manipulations of the training data in order to improve the parsing accuracy. LÄS MER

  4. 3. 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

  5. 4. Invasive interactive parallelization

    Författare :Mikhail Chalabine; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Compiler; refactoring; reasoning; transformation; syntax; composition; component; weaving; Computer science; Datavetenskap;

    Sammanfattning : While looking at the strengths and weaknesses of contemporary approaches to parallelization this thesis s uggests a form of parallelizing refactoring - Invasive Interactive Parallelization - that aims at addressing a number of weaker sides of contemporary methods. Our ultimate goal is to make the parallelization more user and developer friendly. LÄS MER

  7. 5. Novel methods for improved tree breeding

    Författare :Jon Hallander; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The development and implementation of statistical tools to improve inference in sustainable forest tree breeding are presented here. By combining classical quantitative genetic theory and novel statistical methods, a number of parameters are optimized. LÄS MER
