IHI

Welcome to the second meeting of ACM SIGHIT International Health Informatics Symposium -- IHI'12! Springing from the success of IHI'10, IHI'12 continues to be the pivotal forum for presenting research results and sharing experience on the leading-edge issues of computing-oriented health informatics.

This year's symposium attracted over 300 submissions by around 1,000 authors from 37 countries in all continents (except Antarctica), 25% more than that of IHI'10. The percentage of international PC members and conference officers at IHI'12 is 40%, more than doubling that of IHI'10. Over 200 people have served as PC members and conference officers for IHI'12. IHT'12 covers more than 100 topics, which are twice those of IHI'10. This year is the first time that IHI introduces paper tracks, namely analytics, systems, and human factors. The program is also enriched with doctoral consortium, extended abstract, and free tutorial. As a result, the review load of IHI'12 has been controlled under eight reviews per PC member, which is in turn more reasonable and better qualityassured than IHI'10. We hope this year's symposium has successfully set trends and standards for future IHI conferences, as one of the premier international health informatics forums attracting researchers and practitioners from diverse areas in both computer science and medicine. We believe this is important for the development of health informatics, as new progresses can readily benefit from sharing new knowledge and experience and from forging new collaborations across multiple research areas and multiple geographic areas.
