Distributed retrieval system and method oriented to industry metadata registration

Abstract

The invention discloses a distributed retrieval system and method oriented to industry metadata registration. The system comprises the following three modules: a registration module, a storage module, and a distributed retrieval module, wherein the registration module is used for realizing industry metadata registration and sharing across data centers, a data management unit of the data center is used for realizing the metadata self-audit and registration aiming at different industry central and local data centers, and the unit classifies and processes the managed data, injects partial metadata for retrieval into a central node, and all metadata is saved at the local; the data management unit generates inverted indexes for the managed metadata registration, the inverted indexes are distributed in the central and local nodes, and the separation of the data storage and the data management is realized at the same time; the distributed retrieval module is used for realizing the industry metadata sharing across the data centers, and performing distributed retrieval on mass of industry metadata in different data centers. Through the adoption of the system and method disclosed by the invention, the problem of industry metadata sharing across the data centers is solved, mass of industry metadata can be processed in a distributed manner, and the retrieval demand of a user is satisfied.

Description

technical field [0001] The invention relates to an industry-oriented metadata registration and distributed retrieval system and method, belonging to the field of information technology processing. Background technique [0002] Traditional industry metadata search engines index metadata resources, focusing on centralized search. However, with the development of informatization, departments at all levels have accumulated a large amount of metadata. Due to the differences in collection methods, collection time, and processing methods of various departments, industry metadata presents the characteristics of cross-data center distribution. In order to build an information search engine for a certain industry, it is first necessary to uniformly model the heterogeneous industry metadata, then extract and summarize the metadata distributed in various regions and store them in the database, and finally carry out the summary of the metadata resources Audits are indexed for search eng...
