Embodiment Construction

[0034] In order to describe the present invention in more detail, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] The main process of the text retrieval method for the ontology knowledge base of the present invention relates to the interaction between the user and the system. The system part mainly provides the ontology knowledge base and text retrieval method of the corresponding field, and provides access to the outside. The user can access the system at will To connect and retrieve the device. Such as figure 1 As shown, the specific process of the text retrieval method includes:

[0036] (1) Enter the query content, the user connects to the system through the device and enters a text describing the knowledge needs, and then submits a search request to the system.

[0037] (2) Text word segmentation. In the dictionary tree mapped by the domain lexicon, all substrings of...

Abstract

The invention discloses orient field self body intelligence library article search method, the method bases on respective filed related specialized term and builds field verb library; field verb library adopts Chinese dictionary tree structure search; acquires user input enquiry word article, bases on field verb library, enquire word article divides verb and filters, resulting in enquire central; enquire central key verb exchanges, resulting in intelligence demand; bases on which, self body intelligence library searches respective intelligence information. The method bases on respective field intelligence information and builds field verb library, bases on the field verb library and series calculation exposits described word article, and acquires user intelligence demand, and from self body intelligence library acquires respective intelligence information, raises search quality.

Description

Technical field [0001] The invention belongs to the field of information technology, and specifically relates to a field-oriented ontology knowledge base text retrieval method. Background technique [0002] The knowledge base is a relatively independent program entity that connects pieces of knowledge to solve problems in a specific field. On top of this, the ontology knowledge base uses the characteristics of ontology to describe the internal connections between knowledge, and solves the semantic problem of information sharing, so that computers can understand and use knowledge to provide semantic-level knowledge services. [0003] Although the ontology knowledge base can express knowledge well, how to understand the needs of users and provide corresponding knowledge services is a problem. Existing technologies usually match relevant content in the knowledge base based on the keywords entered by the user and return it. This situation often requires users to clearly analyze their ...
