Information Integration and Interoperation
Prof. Ami Motro
With the increased availability of information resources, arguably the
most challenging issue in information systems today is information
integration and interoperation. Yet, the issue has persisted, in
different flavors, for more than three decades.
In this course we shall examine issues of information integration and
interoperation. Among other topics, this course will cover:
Historical perspective: Early definitions of the problem and early solutions
from the 1980s.
Revisiting the issues in the 1990s: mediation.
The problem that won't go away: semantic integration in this decade.
Integration of Web information, semi-structured databases and XML.
Inconsistency resolution, data fusion.
INFS-614: Database Management or permission of instructor.
Each student is required to define a project, present its
finding to the class, and write a final paper on the work. The
presentations and papers need not be excessively long, but should be
of high quality. Students will be evaluated on a combination of (1)
quality of work, (2) presentation, (3) paper, and (4) contributions to
The scope and topic of the project will be negotiated between the
student and the instructor. Students may select topics that relate to
their current work or research interest. Projects may involve a
survey of a specific topic, an investigation of a new idea,
experimentation with a software system directly related to the course,
etc. Projects of larger magnitude can involve groups of 2-3 students.
