The paper describes a dynamic framework for the construction and maintenance of an expert-finding repository through the continuous gathering and processing of online information.An initial set of online sources, relevant to the topic of interest, is identified to perform an initial collection of author profiles and publications.The extracted information is used as a seed to further enrich the expert profiles by considering other, potentially complementary, online data sources.The resulting expert repository is represented as a graph, where related author profiles are dynamically clustered together via a complex author disambiguation process leading to continuous merging and splitting of nodes.Validation of the proposed approach shows an improvement of 17% of the results from DBLP.
