Experienced researcher with significant experience in natural language processing, computational linguistics
Strong background in vector space modeling and multilingualism
Proficient in big data analysis
Proven team player with exceptional track record of delivering consistently high standard performance
I am interested in a variety of topics in NLP, computational linguistics, computational language acquisition and machine learning. My main research area is multilingual vector space models.
MultilingualWS353: MultilingualWS353 is a translated dataset of the popular wordsim353 dataset to the following three languages: German, Italian and Russian. The translated dataset which consists of 350 word pairs in each langauge was annotated for similarity by human evaluators through the CrowdFlower crowdsourcing service based on annotation guidelines in the corresponding language.
MultilingualSimLex999: MultilingualSimLex999 is a translated dataset of the popular SimLex999 dataset to the following three languages: German, Italian and Russian. The translated dataset which consists of 999 word pairs in each langauge was annotated for similarity by human evaluators through the CrowdFlower crowdsourcing service based on annotation guidelines in the corresponding language.
