Implementation method of open source software acquisition and searching system

Abstract

An implementation method of an open source software acquisition and searching system comprises the steps as follows: relational database management software is configured on an enterprise server, so that business-layer codes can access and refresh information in database in the form of objects when an upper application program calls a relational database; an input definition of a user is received, a certain number of open source community sets with known URL (Uniform Resource Locator) address are determined, and open source software home pages in open source communities are captured by crawlers; information, namely open source attributes in the open source software field are extracted from the captured home pages; cross community project information is integrated, an attribute union set is adopted when projects originating from different communities have different attributes, and the dependency relationships among the different projects are saved at the same time; an inverted index is built for the obtained open source attributes; in order to response the user search input or a predefined ranking mechanism, the open source projects that need to be shown are ordered and displayed, so that the acquisition and the searching of the open source software projects can be achieved.

Description

technical field [0001] The invention relates to an implementation method of an open source software acquisition and search system, in particular to a construction method of an open source software search system based on directional web crawlers and information extraction in an environment across multiple open source communities. Background technique [0002] In recent years, the open source software movement at home and abroad has achieved vigorous development, and has formed many open source software ecosystems with a large number of developers, open source projects and open source communities for software development and application. At present, the open source software industry has the following development trends: [0003] 1. The number of open source projects and developers is huge and growing steadily year by year; [0004] 2. A small number of excellent open source projects develop rapidly and are widely used; [0005] 3. Most open source projects are at a low level...

AI Technical Summary

Problems solved by technology

[0005] 3. Most open source projects are at a low level of development and in a state of slow development;

The open source software information in the open source Chinese community mainly comes from manual editing by users, with obvious limitations in quantity and quality; the open source resources in the CSDN community are mainly toolkits or code libraries shared and uploaded by users themselves; the sources are mixed and the format is not uniform , the description is incomplete; while the open source software of the Linux community is mainly limited to packages and tools related to the Linux system

Generally speaking, these communities currently lack an open source software information base with wide coverage, comprehensive data, and uniform format, and a search engine technology based on this information base that provides recommendations and assistance for users to query and select open source software
