The invention discloses a preset
parsing method for a tourism
vertical search engine. The method can analyze
search words of a user, conduct semantic analysis, further combine rules after matching with a plurality of rule engines, and eventually convert the
search words to query conditions that meet user's requirements. The method of the invention can conduct semantic
parsing based on search word text, understand the intent of user's
search words, map an original request to query conditions that are more suitable for user's requirements, and make query result more accurate. The flexible multi-
rule engine application method of the invention facilitates developers self-defining more
rule engine and optimizing search results. After a rule
database is modified, the preset
parsing automatically identifies modification content through
timestamp, and the preset parsing service is dynamically updated, and the
rule engine is updated through a newly opened memory space, so that the preset parsing service is not interrupted, which facilitates operations personnel rapidly adjusting search results based on key words without performing development and code issuing, thereby substantially increasing operation efficiency.
