Problems solved by technology

However, in a comprehensive search system, the semantics associated with a keyword is very broad, that is to say, a keyword may fall into multiple different semantic categories. If these semantic categories are modeled with different semantic structures, then the same as The semantic structure associated with this keyword varies widely. Users cannot guess the target semantic structure and the system cannot provide an interface for querying by fields.

Embodiment Construction

[0032] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Methods of Information Object Search

[0034] figure 1 It is the storage tree structure of semantic structure and network resource URI or its prefix association library. There is only one node at depth 0, the root node, which is a virtual node. A network resource URI can be decomposed into multiple parts step n , according to the URI specification RFC2396, usually takes the following format:

[0035] : / / ？

[0036] The network resource URI prefix in the present invention refers to only the first few parts of the above format.

[0037] The naming scheme (scheme) and the host name (authority part) constitute a node with a depth of 1, and the path (path) part can be further decomposed into multiple steps, for example, the network resource http: / / www.gooseeker.com / cn / node / document / metastudio / operationv3 / bookfront, the nam...

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...
