Entity Information Retrieval System Based on EPC Network

摘要

With the further development of RFID and intelligent sensor technology, the Internet of Things develops from a fuzzy concept to the concreting technology. One of the typical applications of Internet of Things is EPC network. EPC (Electronic Product Code) network is an open-loop framework using EPC as unique identifier to organize entity, storing and sharing information through organizational boundaries. For the current EPC network, it has been achieved for an item level traceability of electronic information, but function of information retrieval is relatively weak. This paper deeply analyses the characteristics of EPC Discover Service and demand of entity information retrieval, and puts forward a rich discovery service to support entity information retrieval. Gaia is an entity information retrieval engine with good extension performance, flexible architecture and functional.
