1. 1. Why the pond is not outside the frog? Grounding in contextual representations by neural language models

   Författare :Mehdi Ghanimifard; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational linguistics; Language grounding; Spatial language; Distributional semantics; Computer vision; Language modelling; Vision and language; Neural language model; Grounded language model;

   Sammanfattning : In this thesis, to build a multi-modal system for language generation and understanding, we study grounded neural language models. Literature in psychology informs us that spatial cognition involves different aspects of knowledge that include visual perception and human interaction with the world. LÄS MER

3. 2. Splitting rocks: Learning word sense representations from corpora and lexica

   Författare :Luis Nieto Piña; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; language technology; natural language processing; distributional models; semantic representations; distributed representations; word senses; embeddings; word sense disambiguation; linguistic resources; corpus; lexicon; machine learning; neural networks;

   Sammanfattning : The representation of written language semantics is a central problem of language technology and a crucial component of many natural language processing applications, from part-of-speech tagging to text summarization. These representations of linguistic units, such as words or sentences, allow computer applications that work with language to process and manipulate the meaning of text. LÄS MER

4. 3. 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

5. 4. Authentic Language : Övdalsk, metapragmatic exchange and the margins of Sweden’s linguistic market

   Författare :David Karlander; Kenneth Hyltenstam; Christopher Stroud; Tomas Riad; Judith T. Irvine; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; authenticity; history of linguistic thought; indexicality; linguistic anthropology; linguistic minorities; metalanguage; metapragmatics; philosophical anthropology; Övdalsk; autenticitet; filosofisk antropologi; indexikalitet; lingvistisk antropologi; metaspråk; metapragmatik; språkliga minoriteter; språkvetenskapens idéhistoria; älvdalska; Bilingualism; tvåspråkighet;

   Sammanfattning : This compilation thesis engages with practices that in some way place stakes in the social existence of Övdalsk (also älvdalska, Elfdalian, Övdalian), a marginal form of Scandinavian used mainly in Sweden’s Älvdalen municipality. The practices at hand range from early 20th century descriptive dialectology and contemporary lay-linguistics to language advocacy and language political debate. LÄS MER

7. 5. 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.
