Alborz: A Query-Based Tool for Software Architecture Recovery**This work was funded by IBM Canada Ltd. Laboratory - Center for Advanced Studies (Toronto) and the National Research Council of Canada.

Alborz is a user assisted reverse engineering tool designed for analyzing and recovering the architecture of a software system in the form of cohesive modules and subsystems. The tool's operation is based on techniques from the area of data mining, pattern matching, and clustering (Figure 1).
