In this paper we address Grand Challenge C-GC1 by comparing the effectiveness of computing idf based only on the local terms in the query, versus computing it based on general term usage as documented ... Results of the experiment show that the local idf approach exceeds or matches the global approach in all of the cases studied. ... CONCLUSIONS This report evaluated the impact of computing idf values using frequencies obtained from the ANC instead of from the local dataset. ...doi:10.1145/1987856.1987874 dblp:conf/icse/CzaudernaGLLSKC11 fatcat:f5tbg6oifrdjbnxcutnhycurei
The objective of this study is to produce a map of work on IR-based trace recovery, with a particular focus on previous evaluations and strength of evidence. ... from evaluations using datasets containing less than 500 artifacts. ...

The aim of this paper is to present and evaluate the usefulness of R2RS metrics in predicting the set of classes impacted by a requirement. ... We evaluate if R2RS is useful for predicting impacted classes in combination and against four other families of metrics that are based upon temporal locality of changes, direct similarity to code, complexity ...
