Requirement Dependency Detection Service

This service was created as a result of the OpenReq project funded by the European Union Horizon 2020 Research and Innovation programme under grant agreement No 732463. This project uses the Connexion library on top of Flask.

Technical description

What does the service do

This service analyzes a given set of requirements and finds requirement pairs which potentially depend on each other by measuring the similarity between the both requirements of the pair. The recommended requirement pairs are those whose similarity is not too high but also not too low. The implemented approach is a very basic unsupervised technique which can only detect dependencies on a content-based level. A more sophisticated supervised approach which requires training data and goes beyond this basic concept is explained in the OpenReq paper of Atas et al.: https://ieeexplore.ieee.org/abstract/document/8609673
