Research On The Analysis Method Of Chinese Address Location Semantic

With the rapid development of the Internet,location based services are widely used in people's lives.The Internet provides a wealth of address information.However,due to the sharing characteristics of the Internet,the expression of Chinese address from the Internet is diversified with many problems such as chaos,incomplete,information loss and information redundancy.It makes the ambiguous of Chinese address semantic information and greatly hampers the computer to directly understand the geographic information semantics described in this address information so that such Chinese address information can not be used directly by the computer for location services.Therefore,in order to make the Chinese address has perfect location semantic information,so that it can be directly applied to the location of the computer services,the study of Chinese address obtained from the Internet location semantic analysis method has important application value.This thesis is based on the web crawler way to obtain the Chinese text address from the Internet as a research object on the Chinese address location semantic analysis method to study.Through the analysis of the Chinese text address data set,the Chinese address can be divided into administrative divisions and street number.In view of the problem of incomplete administrative divisions of Chinese address,first,in this thesis,we use the moving window algorithm to extract the administrative divisions information in the address string and return all possible administrative divisions sets.Then,on this basis,the administrative partition extraction algorithm based on the set operation is adopted to eliminate the ambiguity of the administrative divisions set extracted by the moving window algorithm.And the algorithm extracts the most complete and the largest credibility administrative division.In view of the ambiguity of the Chinese address street number,this thesis uses the Chinese address resolution and semantic annotation method to analyze the location semantic information of Chinese address information.The algorithm uses a Chinese address elements segmentation algorithm based on Bayesian,syntax analysis and semantic annotatation to obtain a complete Chinese address with the location semantic information.In this thesis,the Chinese address analysis method are used the Chinese address data from the Internet to experiment,and the final experimental results are deeply analyzed and compared with other related algorithms.Experimental results show that the algorithm used in this thesis has a high accuracy.For extracting and analyzing the Chinese address information administrative division,the algorithm in the thesis has good effect,and it can cut out the address element information and carry out the processing of syntactic analysis and semantics annotation.So that the algorithm in the thesis make the Chinese address have the structure and location semantic information,which can be well directly applied to the location service for computers.
