  1. 11. Text Representations and Explainability for Political Science Applications

    Författare :Denitsa Saynova; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political Science; Explainability; NLP; Representation;

    Sammanfattning : This work explores the utility of natural language processing approaches for the study of political behavior by examining two main aspects - representation and explainability. We investigate how current representation approaches capture politically relevant signals in a proportional representation system. LÄS MER

  3. 12. Word Vector Representations using Shallow Neural Networks

    Författare :Oluwatosin Adewumi; Marcus Liwicki; Marco Kuhlmann; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Word vectors; NLP; Neural networks; Embeddings; Maskininlärning; Machine Learning;

    Sammanfattning : This work highlights some important factors for consideration when developing word vector representations and data-driven conversational systems. The neural network methods for creating word embeddings have gained more prominence than their older, count-based counterparts. LÄS MER

  4. 13. The Search for Syntax : Investigating the Syntactic Knowledge of Neural Language Models Through the Lens of Dependency Parsing

    Författare :Artur Kulmizev; Joakim Nivre; Roger Levy; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; syntax; language models; dependency parsing; universal dependencies; Datorlingvistik; Computational Linguistics;

    Sammanfattning : Syntax — the study of the hierarchical structure of language — has long featured as a prominent research topic in the field of natural language processing (NLP). Traditionally, its role in NLP was confined towards developing parsers: supervised algorithms tasked with predicting the structure of utterances (often for use in downstream applications). LÄS MER

  5. 14. Automatic and unsupervised methods in natural language processing

    Författare :Johnny Bigert; Viggo Kann; joakim Nivre; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Datalogi; Computer science; Datalogi;

    Sammanfattning : Natural language processing (NLP) means the computer-aided processing of language produced by a human. But human language is inherently irregular and the most reliable results are obtained when a human is involved in at least some part of the processing. However, manual workis time-consuming and expensive. LÄS MER

  7. 15. Language Engineering in Grammatial Framework (GF)

    Författare :Janna Khegai; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Russian resource grammar; natural language processing NLP ; graphical user interface GUI ; syntax editing; computational linguistics; interlingua; multilingual authoring; machine translation MT ;

    Sammanfattning : The basis for the work presented is Grammatical Framework (GF)a grammarformalism based on type theory. It is also a powerful language processorthat provides a convenient framework for various multilingual applications.The primary concern of this thesis is the usage of GF as a piece of software. LÄS MER
