Current and Future Challenges in Mining Large Networks

We report on the Second Workshop on Mining Networks and Graphs held at the 2015 SIAM International Conference on Data Mining. This half-day workshop consisted of a keynote talk, four technical paper presentations, one demonstration, and a panel on future challenges in mining large networks. We summarize the main highlights of the workshop, including expanded written summaries of the future challenges provided by the panelists. The current and future challenges discussed at the workshop and elaborated here provide valuable guidance for future research in the field
