Abstract
A computer-implemented method is provided for detecting characteristics of usages of problem expressions for each of multiple authors. The method includes providing, by a hardware processor, a set of regular expression patterns configured to detect the problem expressions. The method further includes detecting, by the hardware processor based on the set of regular expressions, respective sets of the problem expressions which are (i) used in each of multiple analysis units, (ii) associated with a respective one of each of the multiple authors, and (iii) associated with a respective one of each of multiple artifact types. The method also includes finding, by the hardware processor using automatic feature selection, a set of important expressions in the respective sets of problem expressions. The method additionally includes detecting, by the hardware processor, a typical tendency of the usages of the problem expressions for each of the multiple authors, based on the important expressions.
