A context model for IDE-based recommendation systems

To assess whether the proposed contextual factors are informative for a context model, we statistically evaluated the correlations between IDE command usage and different situations, as they are described by the factors. If a contextual factor correlates with the usage of a command this means that the user is using the command differently when the values of the contextual factor change. We discovered that different factors correlate with different commands and that all the factors correlate with some commands, hence, when a context change is detected, we can also expect a change in the interaction with an IDE.
