CONSTRUCTION METHOD AND DEVICE FOR EVENT REPOSITORY

摘要

Proposed are a construction method and device for an event repository. The construction method comprises: recognizing a text to make out an event excavation candidate sentence; segmenting the recognized event excavation candidate sentence to obtain a syntax fragment; generating event knowledge instances according to the syntax fragment and a pre-defined event knowledge structure, wherein the number of the event knowledge instances is equal to the number of verb-object fragments and subject-predicate fragments contained in the syntax fragment; obtaining the corresponding event excavation target sentence according to the verb-object fragments and subject-predicate fragments contained in the syntax fragments, classifying the components of the obtained event excavation target sentence, and writing the classified component into an event knowledge instance so as to complete the establishment of the repository. In the present invention, an event repository can be constructed via a pre-defined event knowledge structure, and accurate search results can be provided for a user based on the event repository, and the search experience of the user can be improved.
