- Profile
-
Professor Kalina Bontcheva is a senior researcher in the Natural Language Processing Group. From October 2015 she has been working on an EPSRC Career Acceleration Felllowship on summarisation of social media.
- Research interests
-
Professor Kalina Bontcheva is working on NLP for social media, semantic search, GATE, crowdsourcing of NLP corpora, and collaborative text annotation. She is demos co-chair at ACL'2014 and helped co-organise the biannual conference "Recent Advances in Natural Language Processing".
Professor Bontcheva led the PHEME EU project on computing veracity of social media content. She is also the PI of the TrendMiner and DecarboNet European projects, and a Co-I of the uComp project. Earlier in 2013 she completed leading the JISC-funded EnviLOD project.
Between 2006 and 2009 she was the Principal Investigator (PI) on 3 EU-funded projects (MUSING, TAO, and ServiceFinder) and the co-ordinator of the TAO consortium, which involved 7 partner institutions.
Between 2004 and 2006 Professor Bontcheva was Sheffield's technical project manager and researcher on the SEKT Integrated Project. Before that, she was Sheffield's technical manager and researcher on the MIAKT e-science project and also contributed to the AKT project. She has been working on Sheffield's GATE open-source NLP infrastructure since 1999.
