Welcome to LSDIS
About the Lab

The LSDIS (Large Scale Distributed Information Systems) lab was established in 1994 with the guidance and direction provided by Dr. Amit P. Sheth with the help of Dr. John A. Miller and Dr. Krzysztof J. Kochut. This faculty group has been further strengthened by the additions of Dr. I. Budak Arpinar and Dr. Prashant Doshi, as LSDIS faculty members, and Dr. Leonidas Deligiannidis and Dr. Lakshmish Ramaswamy, as LSDIS associate faculty members.

Over the years LSDIS has been actively involved in research projects in the areas of Databases, Workflows, Information Integration, Web Services and the Semantic Web initiative. Students working in the lab frequently do internships in industry during their study, participate in international conferences and are aggressively pursued by potential employers. This trend has lead to several long-lasting collaborations with industry partners. Through its collaborations with industry partners, the lab is able to achieve significant technology transfer. Boeing, MCC, LGERCA and Hewlett Packard Labs have joined the LSDIS Lab as industry sponsor/affiliates in the past. More recently there has been collaboration with Athens Heart Center, IBM TJ Watson, IBM Almaden, CISCO, CTA, Lockheed Martin, Semagix and others.

Research Projects

Semantic Reconciliation with Disparate Sensor Meta-Data for Automatic Publication.
Microsoft SensorMap 2007 RFP Award

As ontologies become the preferred ways for storing data, sensor data providers are likely to develop detailed ontologies for their sensor data descriptions. However, currently envisioned and realized frameworks for publication of sensor data, such as the SenseWeb, do not provide a way to utilize provider-defined ontological representations of the sensor data. Instead, they require the provider to undertake potentially tedious and complex ways of registering their sensor feed data with them. Our research considers the provider-defined data models and automatically identifies and semantically aligns relevant concepts from the provider-defined data models with those of the publisher's data models.

Semantic Discovery: Discovering Complex Relationships in Semantic Web: A NSF Medium Itr project

The SemDis (Semantic Discovery) project involves research in efficient ways to find semantic associations in large data sets. New approaches are developed for indexing and querying of complex semantic relationships driven by notions of information trust, provenance and models of hypotheses. Learn more.

Bioinformatics for Glycan Expression
Integrated Technology Resource for Biomedical Glycomics: Technological Research and Development Project IV, A Project funded by NIH

The goal of the Bioinformatics Project 4 of this glycomics resource is to develop a suite of databases along with computational tools that facilitate efficient acquisition, description, analysis, sharing and dissemination of the data contained therein. Learn more.
