  1. 16. Word Representations for Emergent Communication and Natural Language Processing

    Författare :Mikael Kågebäck; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Extractive summarisation; Emergent communication; Deep reinforcement learning; Natural language processing; Word Representations; Deep learning; Machine learning; Artificial neural networks;

    Sammanfattning : The task of listing all semantic properties of a single word might seem manageable at first but as you unravel all the context dependent subtle variations in meaning that a word can encompass, you soon realize that precise mathematical definition of a word’s semantics is extremely difficult. In analogy, humans have no problem identifying their favorite pet in an image but the task of precisely defining how, is still beyond our capabilities. LÄS MER

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

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

    Sammanfattning : 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. 18. Multilingual text generation from structured formal representations

    Författare :Dana Dannélls; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coherence; computational linguistics; coreference; corpus linguistics discourse structure; knowledge representation; language technology; lexical semantics; linked open data; multilingual natural language generation; natural language processing; ontology; semantic web.;

    Sammanfattning : This thesis aims to identify the optimal ways in which natural language generation techniques can be brought to bear upon the problem of processing a structured body of information in order to devise a coherent presentation of text content in multiple languages. We investigate how chains of referential expressions are realized in English, Swedish and Hebrew, and suggest several coreference strategies that can be used to generate coherent descriptions about paintings.

  7. 20. Contracts and Computation — Formal modelling and analysis for normative natural language

    Författare :John J. Camilleri; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; normative texts; contract analysis; controlled natural language; model checking;

    Sammanfattning : Whether we are aware of it or not, our digital lives are governed by contracts of various kinds, such as privacy policies, software licenses, service agreements, and regulations. At their essence, normative documents like these dictate the permissions, obligations, and prohibitions of two or more parties entering into an agreement, including the penalties which must be paid when someone breaks the rules.
