Dr. Feiyu Xu is Senior Researcher and Project Leader in the Language Technology Lab of DFKI.

She also is co-founder of Yocoy Technologies GmbH , a 2007 spin-off from DFKI. Yocoy is developing next generation mobile language and travel guides such as yochina and i-You.

Since 2004, Dr. Xu is vice-director of the Joint Research Laboratory for Language Technology of Shanghai Jiao Tong University and Saarland University.

She studied technical translation at Tongji University in Shanghai with a waiver of the national admission exam in year 1987,  a high honor for outstanding students. She then studied computational linguistics at Saarland University from 1992 to 1998 and graduated by receiving a Diplom (MSc) with distinction for a thesis on "Semantic Underspecification and Ellipsis Resolution". She joined DFKI in 1998. In 2007 she obtained her PhD in the area of information extraction for a thesis on "Boostrapping Relation Extraction from Semantic Seeds".

She has extensive experience with building multilingual and monolingual information systems and leading ICT projects. Her research areas include information extraction, information mining, semantic web technologies, question answering, opinion mining, dialogue systems,  language learning and mobile applications of language technologies.  She has been involved in more than ten national, EU and international projects.
