Expertise identification and visualization

Visual analysis of knowledge expertise is becoming an emerging field due to its vital and essential importance of discovering both expertise and experts in practical applications. There are numerous visualization techniques which can identify the knowledge domains of research groups and communities. In this paper, we visualize and identify the expertise of an individual author based on the analysis of the author's profile and its available information in DBLP databases. We have presented an approach to analyze both knowledge domains of individual authors as well as topic wise experts. In order to validate and comparison, we use the Gephi visualization tool to observe what is similar (comparison) or difference (contrast) between our proposed methodology and Gephi.
