要旨:
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).
