1. 1. A Lexical Comparison Using Word Embedding Mapping from an Academic Word Usage Perspective

   Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

   Författare :Xuemei Cai; [2020]
   Nyckelord :;

   Sammanfattning : This thesis applies the word embedding mapping approach to make a lexical comparison from academic word usage perspective. We aim to demonstrate the differences in academic word usage between a corpus of student writings and a corpus of academic English, as well as a corpus of student writings and social media texts.

3. 2. Low Supervision, Low Corpus size, Low Similarity! Challenges in cross-lingual alignment of word embeddings : An exploration of the limitations of cross-lingual word embedding alignment in truly low resource scenarios

   Sammanfattning : Cross-lingual word embeddings are an increasingly important reseource in cross-lingual methods for NLP, particularly for their role in transfer learning and unsupervised machine translation, purportedly opening up the opportunity for NLP applications for low-resource languages.  However, most research in this area implicitly expects the availablility of vast monolingual corpora for training embeddings, a scenario which is not realistic for many of the world's languages.
