    Sammanfattning : Word embedding is a technique for associating the words of a language with real-valued vectors, enabling us to use algebraic methods to reason about their semantic and grammatical properties. This thesis introduces a word embedding method called principal word embedding, which makes use of principal component analysis (PCA) to train a set of word embeddings for words of a language.

    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

    Sammanfattning : What are the linguistic characteristics of French newspapers headlines? Employing three aspects of linguistic analysis (syntax, pragmatics and stylistics), the present thesis describes and analyses the textual "genre" of the headline. The author regards a newspaper headline as an autonomous text which carries various functions within the newspaper's discourse and therefore has specific features as regards language use. LÄS MER
