Nicolay Rusnachenko

A research scientist (PhD student) at BMSTU supervised by Natalia Loukachevitch at MSU, where work on Sentiment Attitudes Extraction task. The study is partially supported by RFBR. Meanwhile the job is devoted to development on .NET platform. The latter allows to consider the research as a toolkit development for Sentiment Attitudes Extraction.

Application of Distant Supervision in model training process results in a weight distribution biasing: frames in between subject and object of attitude got more weight values; the latter reflects the pattern of frame-based approach, utilized in RuAttitudes collection development.
