The Research of Non-back Multi-words Matching Algorithm Based on Aggregate Address Inverted Index

摘要

The generation of massive information makes the development and application of information retrieval technology become inevitable. The construction of the inverted index can complete the information retrieval effectively, but it didnȁ9;t consider the accuracy and quickness of the information retrieval. The paper which based on the inverted technology put forward the aggregate addresses inverted index technology to complete the main design of the index system;The use of the improved relevance ranking algorithm and the non-back multi-words matching algorithm complete the main design of the query system. It can adjust the balance of the performance between index and query. The results of system tested indicate that has better universality, higher performance and better scalability of the scale.
