One of the most critical steps to integrating heterogeneous e-Business applications using different XML schemas is schema matching, which is known to be costly and error-prone. Many automatic schema matching approaches have been proposed, but the challenge is still daunting because of the complexity of schemas and immaturity of technologies in semantic representation, measuring, and reasoning. The dissertation focuses on three challenging problems in the schema matching. First, the existing approaches have often failed to sufficiently investigate and utilize semantic information imbedded in the hierarchical structure of the XML schemas. Secondly, due to synonyms and polysemies found in natural languages, the meaning of a data node in the schema cannot be determined solely by the words in its label. Thirdly, it is difficult to correctly identify the best set of matching pairs for all data nodes between two schemas. To overcome these problems, we propose new innovative approaches for XML schema matching, particularly applicable to XML schema integration and data transformation between heterogeneous e-Business systems. Our research supports two different tasks: integration task between two different component schemas; and transformation task between two business documents which confirm to different document schemas.

UMBC will host a three-day in-service training workshop for 35 Maryland high school computer science teachers sponsored by Google. The UMBC CS4HS Workshop will be held 17-20 July 2011 at UMBC's campus in suburban Baltimore.

Workshop attendees will have the opportunity to share ideas for energizing the teaching of computer science in Maryland high schools and to forge new relationships among each other and with university faculty members. A few key high school and state administrators will also be invited to participate. The workshop is being organized by CSEE Professor Marie desJardins.

A $50 registration fee will cover all meals and on-campus housing during the event. A reduced-rate block of hotel rooms will be reserved for participants who would prefer to stay off campus (off-campus housing is not reimbursable).

CSEE Professors Tim Finin and Anupam Joshi are helping to organize a symposium this fall on Open Government Knowledge: AI Opportunities and Challenges that will be held in Arlington Virginia sponsored by the Association for the Advancement of Artificial Intelligence. The symposium will address the technical and social challenges involved in publishing public government data in ways that make the meaning more explicit and enable reuse.

Websites like data.gov, research.gov and USASpending.gov aim to improve government transparency, increase accountability, and encourage public participation by publishing public government data online. Although this data has been used for some intriguing applications, it is difficult for citizens to understand and use. The symposium will explore how AI technologies such as the Semantic Web, linked data, information extraction, statistical analysis and machine learning can be used to make the knowledge embedded in the data more explicit, accessible and reusable. The symposium’s location of Washington, DC will facilitate the participation of U.S. federal government agency members and enable interchange between researchers and practitioners.
