One of the challenging tasks in the context of the Semantic Web is to automatically extract instances of binary relations from Web documents -for example all pairs of a person and the corresponding birthdate. In this paper, we present LEILA, a system that can extract instances of arbitrary given binary relations from natural language Web documents -without human interaction. Different from previous approaches, LEILA uses a deep syntactic analysis. This results in consistent improvements over comparable systems (such as e.g. Snowball or TextToOnto).
The project presented in REF is an automatic approach that can extract instances of arbitrary given binary relations from natural language.
