Abstract

The invention discloses a literature technical index disclosure retrieval method, which comprises the following steps: establishing stylistic metadata; Construct ontology classification table; The metadata of the first-level revelation index is established and the concept of the first-level revelation index is included in the ontology classification table. Constructing the metadata of combinationand realizing the combination retrieval of compound concept; Establishing the metadata of two-level revelation index and revelation index conceptual class; Storing the attribute relationship revealedby the first-level revelation index metadata and the second-level revelation index metadata according to the case metadata in the revelation bibliography data table of a specific set of documents; Through searching ontology class label and selecting style structure metadata attribute or secondary revealing index,searching the special attribute and technical index of concept class and / or its superior concept class and its inferior concept class. Displaying results that match the search criteria. The invention improves the retrieval efficiency, improves the precision ratio of the knowledge content and the technical index, helps the user to realize the automatic clustering retrieval, and improves the recall ratio of the retrieval.

Description

technical field [0001] The invention belongs to the field of document retrieval, and more specifically relates to a retrieval method for document technical index disclosure. Background technique [0002] The current literature information retrieval mainly uses bibliographic data and full-text data for database retrieval. The bibliographic information retrieval method is to process and retrieve the bibliographic data of the entire document by means of classification, title, abstract, subject terms, and metadata association. [0003] Through a comprehensive analysis of the literature collection, it can be seen that the knowledge content and technical indicators related to a specific subject object are networked knowledge composed of knowledge content and technical indicators in multiple documents at different levels scattered in several related fields. Content and index system. The current bibliographic database cannot provide integrated retrieval functions for subject-orien...
