An information retrieval method and device

Abstract

The invention discloses a method and device for information retrieval. The method comprises the following steps: an index server acquires information data from information resources, and determines index entries included in the information data; the index server generates and stores the mapping relationship between the index entry and the information data including the index entry according to the obtained information data and the determined index entry included in the information data; when a retrieval request forwarded by an information retrieval server is received, the index server determines the index entry corresponding to the retrieval request; and the index server determines the information data corresponding to the retrieval request according to the index entry corresponding to the retrieval request and the mapping relationship between the stored index entry and the information data including the index entry, and returns the information data to the information retrieval server, and then the information retrieval server feedbacks the information data to the retrieval request initiator. In the method and the device, the information retrieval efficiency and the expandability in the network management system are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to an information retrieval method and equipment. Background technique [0002] Information Retrieval (Information Retrieval) refers to the process and technology of organizing information in a certain way and finding relevant information according to the needs of users. The full name of information retrieval in a broad sense is information storage and retrieval, which refers to the process of organizing and storing information in a certain way, and finding out the relevant information needed by users from the information collection according to the needs of users. [0003] The main evaluation indicators of information retrieval include the following two aspects: [0004] 1. Retrieval quality: including precision and recall. That is, for a user query request, it should be able to retrieve accurate results that meet the query requirements and retrieve as many results as possible. ...

AI Technical Summary

Problems solved by technology

Therefore, the retrieval of certain business data needs to be retrieved on the information carrier involved in it according to the corresponding information storage format. The information retrieval process is highly coupled with business information, which is not conducive to expansion and maintenance;

[0011] 2. Slow response under large-scale information volume: information resources such as relational databases and network equipment MIB often become the performance bottleneck of the retrieval process under large-scale information volume, resulting in slow information retrieval response;

[0012] 3. The efficiency of multi-service information retrieval is low: due to the inconsistency of information carriers and information structures of different business data, it is often necessary to implement its own information retrieval process

Therefore, multi-service information retrieval needs to use the information retrieval process of each business to retrieve their respective data and finally summarize them. This implementation method may be inefficient under non-concurrent conditions
