Abstract

The invention discloses a quick and accurate retrieval method for finance and taxation data. The method comprises the steps of (1) statically processing the finance and taxation data in a database to generate a static file; (2) initializing a professional word bank in the field of finance and taxation; (3) initializing a common word bank; (4) performing word segmentation on the static file to generate a word segmentation result; (5) filtering the word segmentation result to generate a new word bank; (6) adding words, belonging to the field of finance and taxation, in the new word bank into the professional word bank, and adding other words into the common word bank; (7) generating an index file containing a URL of the static file by configuring Solr and MMSEG4J (Maximum Matching Segment for Java); (8) inputting a retrieval keyword; and (9) returning a retrieval result. According to the method, the access to a case database can be greatly reduced and the website retrieval speed can be increased through page staticization and full-text retrieval technologies.

Description
