SYSTEM AND METHOD FOR EXTRACTING ONTOLOGICAL INFORMATION FROM A BODY OF TEXT

摘要

A system for extracting ontological information from a body of text includes an input module configured to receive a verb phrase. The system also includes a parsing module configured to parse one or more sentences from the body of text into parse tree format to generate a set of parsed sentences. The system further includes a named-entity-recognition module configured to identify a subset of parsed sentences from the set of parsed sentences, identify a subset of noun phrases from the subset of parsed sentences, classify a first noun phrase in subset of noun phrases as an entity, and classify a second noun phrase in subset of noun phrases as a property. The system also includes a concept-extraction module configured to identify and output a conceptual relationship between the first entity and the first property based at least partially on grammatical relationship of the first entity and the first property.

1. A system for extracting ontological information from a body of text, said system comprising:
a processor and executable instructions accessible on a non-transitory computer-readable medium that, when executed, cause the system to perform operations comprising: identify a phrase of a first type; identify a subset of parsed sentences from a set of parsed sentences based at least partially on the occurrence of the first phrase of the first type within at least one parsed sentence of the set of parsed sentences; identify a subset of phrases of a second type from the subset of parsed sentences based at least partially on grammatical relationship of each phrase of the second type of the subset of parsed sentences to the first phrase of the first type; classify a first phrase of the second type in the subset of phrases of the second type as an entity, thereby defining a first entity; classify a second phrase of the second type in the subset of the second type as a property, thereby defining a first property; and identify a conceptual relationship between the first entity and the first property based at least partially on grammatical relationship of the first entity and the first property within a first sentence; and store the conceptual relationship for later use by the system.
