TEMPLATE-DRIVEN STRUCTURED QUERY GENERATION

摘要

An information retrieval system and method are presented. A template is retrieved from a template repository. The template repository stores a plurality of templates. Each of the plurality of templates includes a concept and a relationship from a knowledge model. The knowledge model defines a plurality of entities and interrelationships between one or more of the plurality of entities. The plurality of entities include concepts and instances. The template is transmitted to a client computer, and a statement is received from the client computer. The statement includes an instantiation of the template. A knowledge base is queried using the statement to generate a result listing identifying an item in the knowledge base. The knowledge base identifies a plurality of items. Each of the plurality of items is associated with at least one annotation identifying at one of the entities in the knowledge model.

1. An information retrieval system, comprising:
a knowledge model database configured to store a knowledge model for a knowledge domain, the knowledge model defining a plurality of entities and interrelationships between one or more of the plurality of entities, the plurality of entities including concepts and instances; a knowledge base identifying a plurality of items, each of the plurality of items being associated with at least one annotation identifying at one of the entities in the knowledge model; a template repository storing a plurality of templates, each of the plurality of templates including a concept and a relationship from the knowledge model; and a query processing server configured to:
retrieve one of the templates from the template repository,transmit the template to a client computer,receive, from the client computer, a statement, the statement including an instantiation of the template, andquery the knowledge base using the statement to generate a result listing identifying an item in the knowledge base.
