Information Centric projects: ADEPT, InfoHarness/VisualHarness, InfoQuilt, Video Anywhere

Service Centric projects (including Collaboration and Enterprise Integration): METEOR, CaTCH , CAPA, CareWeb

ADEPT [Alexandria Digital Earth Prototype Modeling System]: The ADEPT project is a collaboration between various academic, corporate, institutional, and government partners, a comprehensive follow-on to the previously funded Alexandria Digital Library Project (ADL). ADEPT aims to use the Digital Earth metaphor for organizing, using, and presenting information at all levels of spatial and temporal resolution. We call the digital environments based on the Earth metaphor Iscapes (Information Landscapes). The research and development activities focus on: (a) creating geospatial information and meta-information collections; (b) building operational services for: discovering heterogeneous, distributed collections; organizing these resources into Iscapes tailored for specific applications; and collaborative use and visualization of Iscapes; (c) applying and evaluating ADEPT services in learning environments; and developing scalable, efficient, and secure systems.

CaTCH: [Collaborative Teleconsulting for Healthcare]: This projects involves integration for several rapidly progressing technologies to support high bandwidth collaboration through access to diverse variety of information over a variety of communications alternatives. CaTCH I supports real-time collaboration by integrating multimedia patient data on Intranet, medical reference data on Internet, LAN/POTS/ISDN-based Video+Data Conferencing, and WWW/Java programming to set up remote environment and context sensitive collaboration. CaTCH II provides asynchronous (store-and-forward) collaboration using a Web-object model to integrate a variety of information such as streaming video of medial information, video or audio mail, patient data, etc. and making it available on demand through Web. Medical College of Georgia is our primary application partner for this project. CaTCH II is being field trialed for supporting consultation on echocardiograph. It is also being extended to support a variety of consultations in healthcare.

CAPA: [Course Approval Process Automation] is an operational, production workflow system developed and supported by the LSDIS. It supports a 30+ step workflow spread over entire UGA campus with a potential user-base of 130+ departments and 3500+ faculty and staff members. It has already been used to support approval of 6000 new courses in a three-month period.

CareWeb: An advanced Web-based system developed in the Georgia's Family Connections program for the Medical College of Georgia to support distance health education and collaboration among patients and healthcare workers.

InfoHarness/VisualHarness: InfoHarness supports search and retrieval of heterogeneous information in intranet/Internet environments. The basic InfoHarness system, and the corresponding commercial product Adapt/X Harness from Bellcore, provides access to heterogeneous textual and semi-structured data without restructuring, reformatting and relocating the data. It also supports logical restructuring of the information space, support for multiple third-party indices and many other features. Research in the joint Bellcore-LSDIS project funded by the Massive Digital Data System initiative addressed several new research issues, including: keyword- as well attribute-based access to data, access to multiple autonomous repositories with independent and heterogeneous indices for scaleable search with associated intelligent merging of results, access to the same repository with multiple indices to improve quality of result, and support for remote severs using CORBA. VisualHarness system is the InfoHarness system enhanced with Zebra component, which provides customizable and extensible search of federated image repositories, in addition to text and semi-structured data, and structured (relational) databases. Through the comprehensive use of metadata of various types, it supports keyword, attribute-based and content-based search over images. This project has been completed, and future work in this area are done in the follow-on InfoQuilt project.

InfoQuilt: This project intends to develop a comprehensive information brokering environment for enabling the Infocosm. It focuses more on the logical and semantic issues though support for a large variety of metadata (content independent, content descriptive, content dependent), context, user models and multiple ontologies for an environment consisting of heterogeneous data sources. Current work includes semantic level information correlation through metadata reference links (MREFs, as extension to HREFs), media-independent search of heterogeneous media (structured data, text, image, video) repositories, context representation, and support for multiple (possibly preexisting) ontologies. The InfoQuilt system also intends to prototype a second generation World Wide Web architecture that would be fully distributed, highly scaleable and extensible utilizing agent technology where the information is managed and manipulated at logical and semantic level (rather than physical hypertext link). Applications of concepts and techniques developed in this project are being considered for Digital Libraries and Geographical Information Systems.

METEOR [Managing End-To-End OpeRations]: The METEOR system focuses on R&D of innovative Multiparadigm Transactional Workflow Management technology. Workflow management techniques and systems developed in this project support coordination of user and automated tasks in real-world multi-enterprise heterogeneous computing environments over Web and CORBA+Java infrastructures. Technical issues involve GUI toolkit for workflow design/monitoring/simulation, automated code generation for distributed workflow application from graphical design, scheduling, EDI, multidatabase access, error/failure handling and recovery (using transactional concepts/techniques) as appropriate, and security. This project is funded through the NIST ATP initiative in Information Infrastructure for Healthcare and involves 17 IT and healthcare institutions. METEOR software have been tested by our industry partners and had been commercialized by Infocosm, Inc. METEOR designer has been made available free of charge to instructors conducting advanced graduate courses in this area.

Video Anywhere: This industry-funded project researches the issues related to management of video in embedded (e.g., cable set top) system running a Java Virtual Machine. It fits into the exciting and fast evolving interactive TV and video application market-place. It involves research in understanding metadata and consumer profile, caching, crawling (using agent technology), etc. Current prototype of this system can be seen as a Web-based search engine for accessing a variety of video assets including streaming videos on the Web, premium TV programming, and local video (such as on DVDs).

METEOR-S [Semantic Web Services and Processes]: The growth of Web services and service oriented architecture (SOA) offers attractive basis for realizing dynamic architectures, which mirror the dynamic and ever changing business environment. With the help of industry wide acceptance of standards like Business Process Execution Language for Web Services (BPEL4WS), Web Service Description Language (WSDL) and Simple Object Access Protocol (SOAP), Web Services offer the potential of low cost and immediate integration with other applications and partners. The METEOR-S project at the LSDIS Lab, University of Georgia aims to extend these standards with Semantic Web technologies to achieve greater dynamism and scalability. Specifically, [Verma et al., 2004a; Sivashanmugam et al., 2003] focus on adding semantics to WSDL and UDDI (this work termed WSDL-S is being provided as input for next version of WSDL that will support semantic representation), [Verma et al., 2004b; Sivashanmugan et al., 2004] focus on adding semantics to BPEL4WS, and [Patil et al., 2004] discusses a semi-automatic approach for annotating Web services described using WSDL.
