Information Systems: Modeling, Development, and Integration: Third International United Information Systems Conference, UNISCON 2009, Sydney, . Notes in Business Information Processing, 20)

UNISCON 2009 (United Information Systems Conference) was the third conf- ence in the series that is based on the idea to pool smaller but highly interesting scienti?c events on information systems into one large conference. Here, people from di?erent scienti?c backgrounds can present their research results, share their ideas and discuss future trends in these various areas. UNISCON 2009 was held in Sydney, Australia in the University of Western Sydney, Campbelltown Campus. In 2009 the following scienti?c events were held under the umbrella of UNISCON 2009: th – 8 International Conference on Information Systems Technology and Its Applications (ISTA 2009) th – 8 International Workshop on Conceptual Modelling Approaches for e- Business (eCOMO 2009) – Second Workshop on Model-Based Software and Data Integration (MBSDI 2009) We received 115 papers for the three events. Papers were submitted from over 25 countries. After a rigorous review process, 39 papers were accepted as full papers and 14 papers as short papers for presentation at the conference and published in these proceedings. In addition to the above three events, we also organized a Doctoral Cons- tium to provide a forum for doctoral students to get feedback from experts in the area about their research projects.

This volume constitutes the proceedings of the Third International United Information Systems Conference, UNISCON 2009, which was held in Sydney, Australia, during April 21-24, 2009.

UNISCON 2009 combines three different events: 8th International Conference on Information Systems Technology and its Applications (ISTA 2009), 8th International Workshop on Conceptual Modelling Approaches for e-Business (eCOMO 2009), and 2nd International Workshop on Model-Based Software and Data Integration (MBSDI 2009).

The overall 39 full papers and 14 short papers presented with two keynote speeches were carefully reviewed and selected from 115 submissions. The topics covered are: information systems modelling; information systems analysis; information systems integration; business process modelling; information retrieval and NLP; e-learning and training; datamining, datawarehousing, and visualization; and Web intelligence.
