摘要
为提高地理编码系统对输入地址的分词适应性及匹配准确度,该文基于Lucene索引及查询机制提出了一种可适应于中文非标准地址的地址匹配改进方法。首先依据中文地址模式创建地址元素分层索引库,然后将拼音三叉树、同义词配置、未登录词配置等功能集成于IK分词器,获得初次匹配结果集合后计算编辑距离并排序选取返回值。匹配系统以浙江省台州市公安地址及行政法人地址为数据基础构建分词库和索引库,结果表明,该方法可实现输入地址的自适应分词,对中文非标准地址的匹配效果良好,能够服务于测绘和地理信息的相关应用场景。
For improving segmentation adaptability and matching accuracy of the input address in geocoding,an improved method of address matching that can adapt to Chinese non-standard addresses was proposed based on Lucene index and query mechanism.Firstly,the method created a hierarchical index library of address elements in view of Chinese address patterns.Secondly,default tokenizer was transformed into a tokenizer with compound functions,including the ternary search trie composed of pinyin,synonym configuration and unregistered word recognition.Finally,Levenshtein distance would be introduced as an indicator of the results after obtaining the first matching set.The matching system built the word segmentation database and index database from address corpus of public security bureau and legal entity of administration in Taizhou city,Zhejiang province.The results indicated that this method could realize the adaptive word segmentation of the input address,and it had a significant matching effect for Chinese non-standard addresses.It provides theoretical and practical support for related application on surveying and mapping and geographic information.
