Bilingual Lexicon Extraction with Temporal Distributed Word Representation from Comparable Corpora
Chunyue Zhang, Tiejun Zhao · Lecture notes in computer science · 2015
Distributed word representation has been found to be highly effective to extract a bilingual lexicon from comparable corpora by a simple linear transformation. However, polysemous words often vary their meanings at different time points in the corresponding corpora. A single word representation which is learned from the whole corpora can’t express the temporal change of the word meaning very well. This paper proposes a simple solution which exploits the temporal distributed word representation for polysemous words . The experimental results confirm that the proposed solution can offer better performance on the English-to-Chinese bilingual lexicon extraction task.
