Offline Text Message Storage and Recovery Based on Inverted Files in Peer-to-Peer Internet Telephony

摘要：

Offline text message based on inverted files provide some new extensible service for user, which let user search in all offline messages to get a satisfied result. Moreover, the message is recovered quickly from the inverted files and resent to user. The scattered original messages need not be reserved after indexing, so the storage space can be saved in the system. This paper discusses the function of inverted index compression, similarity query process and message recovery with block processing in a high efficiency system. The experiments of simple prototype system validate our analytical methods.
