Apparatus for learning classification model and method and program thereof
First Claim
1. A classification model learning apparatus for learning a classification model for extracting a particular event from a text having both a text and information on the existence or nonexistence of the particular event, comprising:
- an evaluation unit configured to evaluate the existence or nonexistence of the particular event for a plurality of learning texts having both a text and information on the existence or nonexistence of the particular event by applying an event related expression for evaluating the existence or nonexistence of the particular event to each learning text of the plurality of learning texts;
an extracting unit configured to extract a learning text in accordance with the existence or nonexistence of the particular event evaluated by the evaluation unit; and
a learning unit configured to learn a classification model based on the learning text extracted by the extracting unit.
