  4. 4. Dependency-based Semantic Analysis of Natural-language Text

    University dissertation from Department of Computer Science, Lund University

    Author : Richard Johansson; Lunds universitet.; Lund University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Natural language processing; syntax; semantics; computer science;

    Abstract : Semantic roles, logical relations such as Agent or Instrument that hold between events and their participants and circumstances, need to be determined automatically by several types of applications in natural language processing. This process is referred to as semantic role labeling. READ MORE
