| Areas of expertise | My research on networks focuses on community detection. I have written the following papers on the subject: -'An algorithm to find overlapping community structure in networks'. -'Local betweenness for finding communities in networks'. -'A fast algorithm to find overlapping communities in networks'. -'Finding overlapping communities using disjoint community detection algorithms'. -'Detecting communities in networks by merging cliques'. -'Finding overlapping communities in networks by merging cliques'. -'Finding overlapping communities in networks by label propagation'. -'Fuzzy overlapping communities in networks'. With Martha Paschali, I proposed Workflow Prolog, a new extension of Prolog. The language allows workflow systems to be implemented in a novel declarative style, while preserving the existing properties of Prolog, such as its familiarity and efficiency. We then demonstrated the expressiveness of the language by showing how it can express each of the workflow patterns that have previously been identified as the requirements of a workflow language. |
