Patent ID: 8533174

Claim:
A multi-entity-centric integrated search system, the system being connected through a wired/wireless communication network and performing computer communication and operation processing, comprising: an entity information acquisition server including: a query term input unit receiving a query term which is composed of keywords input from a user, a query term analysis unit analyzing the query term and generating combinations of entities separated by a delimiter from the query term, wherein the combinations of entities are combinations of the keywords of the query term, an entity search unit searching an entity database for the generated combinations of entities and returning existence of the combinations of entities and types of the combinations of entities as resulting values, an entity and entity type detection unit selecting candidate combinations of entities, all entities of each of which exist in the entity database, among the generated combinations of entities, and an entity and entity type determination unit selecting a final combination of entities from among the candidate combinations of entities, all entities of each of which exist in the entity database, in consideration of a number of entities or a number of entities' types in the candidate combinations of entities, wherein the entity information acquisition server is configured to provide the final combination of entities, and the final combination of entities is a query for making final search results which is provided for users in an integrated search result provision server, and an integrated search result provision server including: unit service calling units acquiring search result values for the final combination of entities, a search result calling unit utilizing at least one of the unit service calling units which is mapped to the final combination of entities selected by the entity and entity type determination unit in consideration of entities' types in the final combination of entities, a unit service result configuration unit setting a method of arranging and outputting the search result values, and an integrated search result presentation unit outputting integrated search results including the arranged search result values, wherein the multi-entity-centric integrated search system comprises a processor and a memory, and wherein the generating of combinations of entities includes generating all combinations of keywords, separated by the delimiter, in consideration of a sequence of keywords.
