Abstract: A computer-implemented method includes training a classification model to produce a mapping from a set of feature vectors to a set of confidence levels. Each feature vector describes a respective term, and each confidence level indicates a likelihood that the respective term is a keyword. A plurality of program artifacts are tokenized into a plurality of terms. For each term in the plurality of terms, a respective feature vector is determined for describing the term, based on the plurality of program artifacts. For each term in the plurality of terms, based on the respective feature vector, using the mapping, a respective confidence level is determined for indicating a likelihood that the term is a keyword of the plurality of program artifacts.

Abstract: Provided is a method, system, and program for performing an impact analysis of program statements in a source code file, wherein each program statement has at least one of an input parameter and output parameter. A selection is received of at least one program statement in the source code file. For each selected program statement, a determination is made of program statements in the source code file having as one input parameter one program artifact that is affected by the selected program statement.
