  • Event-based social network (in progress). This work is to analyze the structure of event-based social network and compare its difference and similarity with conventional social network. Furthermore, we aim to explore the mutual influence between online and offline social interactions among users.
  • User account classification (in progress). This work aims to develop a user classification framework to classify Twitter accounts into human and non-human classes. The classification is based on several types of features such as time, space, text and sentiment.
  • Recommendation system in location-based social network (LBSN). This work aims to develop a location recommendation framework in LBSN. The underline algorithm is based on collaborative filtering and enriched with social and spatial information.
  • Framework for Social Web Search. This work is to develop a search framework for social web where textual relevance and social influence are both considered to rank the document during search.
  • Multi-network analytic tool. This is a tool for assisting analysis and reasoning of a multi-layer network, which consists of three views, namely, Node-link view, Dendrogram view and Map view.
  • Web Flow Analyzer. It is a simple tool for recording web flow from the server to client. Based on these recorded data, some interestings things are revealed. Cleck here for details.
