  1. 1. Syntax-based Concept Alignment for Machine Translation

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Arianna Masciolini; [2023-03-30]
    Keywords : computational linguistic; machine translation; concept alignment; syntax; dependency parsing; Universal Dependencies; Grammatical Framework;

    Abstract : This thesis presents a syntax-based approach to Concept Alignment (CA), the task of finding semantical correspondences between parts of multilingual parallel texts, with a focus on Machine Translation (MT). Two variants of CA are taken into account: Concept Extraction (CE), whose aim is to identify new concepts by means of mere linguistic comparison, and Concept Propagation (CP), which consists in looking for the translation equivalents of a set of known concepts in a new language.

  3. 2. Cross-Lingual and Genre-Supervised Parsing and Tagging for Low-Resource Spoken Data

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Iliana Fosteri; [2023]
    Keywords : dependency parsing; part-of-speech tagging; low-resource languages; transcribed speech; large language models; cross-lingual learning; transfer learning; multi-task learning; Universal Dependencies;

    Abstract : Dealing with low-resource languages is a challenging task, because of the absence of sufficient data to train machine-learning models to make predictions on these languages. One way to deal with this problem is to use data from higher-resource languages, which enables the transfer of learning from these languages to the low-resource target ones. READ MORE

  4. 3. THE LINGUISTIC STRUCTURE OF WIKIPEDIA A multilingual analysis and comparison of the language used in Wikipedia articles

    University essay from Göteborgs universitet / Institutionen för filosofi, lingvistik och vetenskapsteori

    Author : Patricia Grau Francitorra; [2022-06-20]
    Keywords : Abstract Wikipedia; Syntactic Analysis; Universal Dependencies; Grammatical Framework; UDPipe 2.0; Syntactic Patterns;

    Abstract : Wikipedia is a great source of knowledge, but due to its open-collaboration nature, it presents some limitations. Namely, the uneven distribution of content, the low overlap in topic coverage, the differences in the comprehensiveness of articles, and the low number of editors. READ MORE

  5. 4. The Influence of M-BERT and Sizes on the Choice of Transfer Languages in Parsing

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Yifei Zhang; [2021]
    Keywords : ;

    Abstract : In this thesis, we explore the impact of M-BERT and different transfer sizes on the choice of different transfer languages in dependency parsing. In order to investigate our research questions, we conduct a series of experiments on the treebanks in Universal Dependencies with UUParser. READ MORE

  6. 5. Identifying Base Noun Phrases by Means of Recurrent Neural Networks : Using Morphological and Dependency Features

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Tonghe Wang; [2020]
    Keywords : ;

    Abstract : Noun phrases convey key information in communication and are of interest in NLP tasks. A base NP is defined as the headword and left-hand side modifiers of a noun phrase. In this thesis, we identify base NPs in Universal Dependencies treebanks in English and French using an RNN architecture. READ MORE
