Multidimensional Heterogeneous Information Network Analysis and Mining

This research program proposes to address several fundamental problems related to the analysis of massive information networks. Our long-term goal is to develop theories and algorithms for mining knowledge from large-scale time-evolving heterogeneous and multidimensional information networks, that is, networks that consist of multi-typed nodes (entities) and multiple edges (relations) between the network nodes. As driven application, we consider the analysis of large-scale social networks in order to provide better understanding of human-Web interactions and give semantic interpretation and insight into the various roles and groupings in online social networks.

Data Mining for Energy Analysis

This project is conducted in collaboration with a major multinational corporation. The general goal is to use data mining techniques in order to analyse massive data collected from smart meters and energy monitoring system. The aim is to extract useful patterns of actions that offer insight to track and analyze customers’ energy consumption over different time stamps and develop an automatic mechanism to understand consumption trends and provide recommendations for better energy use, achieve energy efficiency goals and improve business operations.

Social Networks Analysis

The increasing amount of communication between individuals in e-formats (e.g. email, instant messaging, blogs, etc.) has motivated computational research in social network analysis. Social network analysis techniques aim to search communities of shared interests or leaders within communities. Social networks are often represented as graphs, where nodes represent individuals and edges represent the relationship between them. Such graphs are massive, in which node may contain a large amount of text data. The goal of this project is to make social network analysis more effective is to develop techniques that take into account textual content, uncertainty, incompleteness, heterogeneity of data sources and the need of developing specialized algorithms for Web applications that involve continuous stream of edges

Learning Models for Time Evolving Networked Data

Todays' networked data are dynamic and change continually over time. Recently, a few methods have been proposed in an attempt to solve this problem. Nevertheless, the vast majority of existing methods encounter difficulties to handle large networks observed over long time periods. There are many open questions that have yet been addressed. In particular, what is the critical time moment in which groups’ membership changes most? What are the most important features that affect community membership over short and long time period? Furthermore, in some situations the whole network is not available at one time, but available in the form of continuous stream (e.g. components of the network are received more or less continuously as time progress). This goal of this project is to create analytical tools to track and predict structural changes and explain the evolution of the network over time. The devised approaches should be able to analytically model the co-evolution of multi-typed entities and the relationships among them.
