Deception Detection

Deception detection has been a long-standing concern of law-enforcement agencies, employers, military, business negotiation, and individuals who are concerned about information quality. Computer-mediated communication introduces new challenges to deception detection research. By integrating information technology and traditional sociological theories and findings, this line of research not only makes unique contributions to deception detection, computer-mediated communication, and human computer interaction research but also creates new possibility for applying and developing information technologies.

The Semantic Web and Ontology

The Semantic Web will transform the Web from a data and communication space into a massive knowledge and service repository. On the one hand, the Semantic Web requires the support of semantic interoperability from ontology. On the other hand, the Semantic Web allows knowledge acquisition and service request and delivery in an unprecedentedly efficient way.

Group Communication

Collaboration or group work is a common phenomenon in modern organizations and businesses. Although technologies or tools in support of group communication are widely available, much remains to be known about group communication behavior, including the impact of information technologies on it, its dynamics and patterns, and its impact on the success of group work and even the entire communities.

Web Services and Service Composition

With the advent of service-oriented computing and the widespread application of Web technologies, the Internet offers unprecedented opportunities to provide interoperable services to streamline supply chain, integrate intra-enterprise processes, and manage customer relationships. Web services standards have been widely accepted. Nonetheless, they are mostly based on syntactic information and are yet to support service discovery beyond keyword matching. Trust may play an indispensable role in selecting and composing services.

Natural Language Processing and Text Mining

Text mining and natural language processing characterize the majority of my technical approaches to knowledge discovery and sharing. Understanding human language and discovering interesting information and relationships from large amounts of text using computers are powerful techniques for automatically discovering and acquiring knowledge from free-formed textual documents and semi-structured Web pages. to pursue research questions.
