2011 Lecture Notes in Computer Science  
In this paper, we explore the use of graph-based similarity search as a tool for expressing queries over model repositories, uniformly represented as collections of labeled graphs.  ...  For reuse to take place, developers must be able to perform effective searches across vast collections of models, locate model fragments of potential interest, evaluate the usefulness of the retrieved  ...  The node type similarity cutoff threshold has been set to 0.6. For the evaluation we performed the 15 queries in all the 9 scenarios and we calculated the average values for the quality measures.  ...
