  • HybridIE: Development of an IE methodology aiming at the specification and evaluation of application criteria for IE-processes, -methods and tools. Funded as FFG BRIDGE program (August 2010 -)
  • OntoJob: Within the OntoJob project, FAW realises Ontology Population in the eRecruitment domain. Funded as FFG COIN program (starting September 2010)
  • Marlies: Marlies aims at the recognition of entities and their relations in the manufacturing domain. Cooperation with Tech2select GmbH, Linz; Funded as FFG BASIS program (April 2008 - ongoing)
  • TourIE: TourIE focuses on the extraction of tourism information from heterogeneously designed accommodation Web sites. Extracted information includes accommodation’s name, available facilities, room price, location, accommodation category, and images. The developed prototype uses a knowledge engineering approach and i based on a tourism domain ontology. (June 2007 - June 2008)
  • Jobolize: Ontology Based Web Information Extraction for eRecruitement. Cooperation with JoinVision GmbH, Vienna; Funded as FFG BASIS program (Mar-Sep 2007, Oct-Dec 2008)
