Abstract

The invention discloses a method and a device for searching an information object. The information object is information content with semantic structure, comprising a plurality of information properties with semantic correlative relation, wherein the information properties are units of different semantic aspect content of information objects; and the semantic structure is collection of semantic metadata. Target webpage URI can be utilized to query correlative library to obtain semantic structure by establishing semantic structure and network resource URI or correlative library of prefix of network resource URI; webpage information is formatted and indexes are established with the guidance of semantic structure; user request is responded, searching results are provided according to correlation order, and simultaneously layering semantic navigation trees are provided; and refine searching results are provided to a user when the user clicks the node of the semantic navigation tree. The invention belongs to the technical field of computer science, is applicable to the application fields of network information extraction, full text search, semantic search, mobile phone search and the like.

Description

technical field

[0001] The invention belongs to the semantic search branch in the field of computer science and technology, and specifically relates to a method and device for information object search, which is suitable for network information extraction, full-text search and semantic search, business intelligence mining, information aggregation, network knowledge base establishment, mobile phone search, etc. application field. Background technique

[0002] Precision rate and recall rate are two important indicators for measuring search engines, but for massive comprehensive search engines, due to the excess of Internet information, the repetition rate is very high. If it is not very good, it can still provide customers with satisfactory search results. However, if the user wants to retrieve some strongly structured information (hereinafter referred to as information object, or object for short, just like the object in object-oriented programming, it is strongly structured...
