Research On Key Technologies Of Multidimensional Project Evaluation For Open Source Ecology

Along with the continuous improvement of the open source concept,the development of the open source community is changing with each passing day,and a large amount of open source software is born.The software resources are highly dispersed and uneven.It is difficult to evaluate the open source software and search for high quality software in a traditional single and closed way.Therefore,it is very meaningful to propose a new open source software sorting algorithm.This paper proposes a new method for comprehensive evaluation of software,which comprehensively evaluates software from objective and subjective levels.Objectively adopt text matching and implicit combination method to establish the association of open source software in the software main community and software derivative community,and then quantify the social group emotional evaluation value of software in the software derivative community.Subjectively,according to the software subject,the corresponding metrics are mined in the corresponding collaborative development community.Finally,quantitative and qualitative analysis are combined to mine four kinds of metrics and quantify the weight of 11 indicators for software quality contribution.Finally,the effectiveness of the multidimensional evaluation method was verified by project evaluation under the design database and IDE categories.This paper redefines the lucene-based text relevance sorting and scoring mechanism in Solr.Based on the text relevance matching software,the software multi-dimensional evaluation value ranking factor is added to form the software sorting algorithm.The algorithm is optimized and verified by the two-stage sorting strategy.By constructing a distributed retrieval tool solrcloud,the qualitative popularity of the software is used as the screening of the system open source software dataset,and finally a distributed system based on multidimensional evaluation for the retrieval and sorting of open source software is realized.Finally,the query test set is compared with the existing software sorting system in the industry.The open source software retrieval optimization method based on multi-dimensional evaluation value is effectively tested,and an efficient,finegrained and comprehensive open source software retrieval system is realized.
