Method for maintaining tracking relationship between requirement item and work product

Abstract

The invention discloses a method for maintaining tracking relationship between a requirement item and a work product, and belongs to the field of computer software engineering. The method comprises the following steps of: 1) inputting requirement specification, a tracking relationship TRold before change and the change information of the work product; 2) for increasing a work product, searching an original work product set WpSetold of which the similarity to the increased work product is more than the set threshold h; 3) for each requirement item in the requirement specification, searching a work product which is related to r in the WpSetold according to TRold, recording the work product as a set WPrUn; 4) using r and WPrUn as the input of a related feedback algorithm, and obtaining a requirement item query r'; 5) using an association relationship that the similarity between the r' and the increased work product is more than the set threshold H as a candidate tracking relationship; 6) for modifying the work product, using the modified work product as an increased work product item, and repeating the steps 2) to 5); and 7) for deleting the work product, deleting the tracking relationship associated with the changed work product item. The method for maintaining the tracking relationship greatly improves degree of automation and efficiency of the tracking maintenance.

Description

technical field [0001] The invention belongs to the field of computer software engineering, and specifically relates to a method for maintaining a tracking relationship between a requirement item and a work product, which realizes automatic update and maintenance of the requirement tracking relationship when the work product changes. Background technique [0002] Requirements traceability is the ability to describe and trace the entire requirements life cycle. Requirements traceability refers to the relationship between requirements and software work products. At present, many organizations use requirements traceability matrix to describe requirements traceability relationship, and establish requirements traceability matrix as requirement A guiding standard process in engineering, which is not only a core activity in CMM / CMMI level 2, but also a necessary activity in clause 4.8 of the software development and maintenance standard ISO9001. Software requirements tracing assist...

The formula of the Mixture Model method is: q'=αq+β·θ r , and where q′ and q denote the original query and the new query respectively; θ r Represents the probability model for generating relevant documents, which can be obtained by the Mixture Model method. It can be seen that the Mixture Model method generally does not consider negative feedback information
