  1. 1. The Multilingual Forest : Investigating High-quality Parallel Corpus Development

    Author : Yvonne Adesam; Martin Volk; Joakim Nivre; Koenraad de Smedt; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; treebank; syntax; alignment; corpus; annotation projection; multilingual; tagging; parsing; datorlingvistik; Computational Linguistics;

    Abstract : This thesis explores the development of parallel treebanks, collections of language data consisting of texts and their translations, with syntactic annotation and alignment, linking words, phrases, and sentences to show translation equivalence. We describe the semi-manual annotation of the SMULTRON parallel treebank, consisting of 1,000 sentences in English, German and Swedish. READ MORE

  2. 2. MaltParser -- An Architecture for Inductive Labeled Dependency Parsing

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

    Abstract : 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.

  3. 3. Cross-language Ontology Learning : Incorporating and Exploiting Cross-language Data in the Ontology Learning Process

    Author : Hans Hjelm; Martin Volk; Joakim Nivre; Philipp Cimiano; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ontologies; Ontology learning; Distributional semantics; Knowledge acquisition; Text mining; Computational linguistics; Datorlingvistik; datorlingvistik; Computational Linguistics;

    Abstract : An ontology is a knowledge-representation structure, where words, terms or concepts are defined by their mutual hierarchical relations. Ontologies are becoming ever more prevalent in the world of natural language processing, where we currently see a tendency towards using semantics for solving a variety of tasks, particularly tasks related to information access.

  4. 4. Hybrid Methods for Coreference Resolution in Swedish

    Author : Kristina Nilsson; Martin Volk; Mats Wirén; Christer Johansson; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; coreference resolution; coreference; anaphora; discourse processing; Computational linguistics; Datorlingvistik; datorlingvistik; Computational Linguistics;

    Abstract : The aim of this thesis is to improve coreference resolution in Swedish by providing a hybrid approach based on combining data-driven methods and linguistic knowledge. Coreference resolution here consists in identifying all expressions in a text that have the same referent, for example, a person or an object. READ MORE
