Program

Motivation

Molecular biology has a communication problem. Many researchers and databases use (at least partially) idiosyncratic terms and concepts for representing biological information. Often, terms and definitions differ between groups, with different groups not infrequently using identical terms with different meanings. The concept "gene", for example, is used with different semantics by the major international genomic databases. Ontologies are one way to provide a semantic repository of systematically ordered relevant concepts in molecular biology. Such repositories can be used, for example, to bridge the different notions in various databases by explicitly specifying the meaning of and relation between fundamental concepts.

Ontologies

An ontology has been variously defined as:

Ontologies are now recogized as essential to information integration and knowledge-based systems in a wide variety of disciplines. This is because ontologies permit knowledge workers to define and share domain-specific vocabularies. Having developed a formal specification for a domain ontology, it is possible for database and software developers to agree on its use. Biology, including molecular biology, genetics, and biochemistry have historically played host to many nomenclature wars and a vast quantity of rather loosely defined terminology. In a rapidly developing scientific discipline, a certain amount of terminological fluidity cannot be avoided, but the level of conceptual casualness has resulted in large and essential databases that are both inconsistent internally and unmanagable as parts of a larger information infrastructure for research.

Part I (Saturday evening) - Tutorial

This tutorial will introduce participants to the background and recent developments in ontology research, ontology specification languages, ontology building methods and tools, and some examples of the use of ontologies in information systems and for semantic integration of diverse information sources in molecular biology. This introduction will help to resolve and assimilate the widely varying terminology in this field and to provide a common basis for the following day workshop.

Part II (Sunday) - Workshop

This one-day workshop will focus on the following aspects of schemata, controlled vocabularies and ontologies for molecular biology and bioinformatics:

The workshop will consist of interactive case studies of conceptual models from existing systems. One goal of the workshop is to assess the current success and "division of labor" among researchers, and evaluate the possibilities for interoperability.

We would also be particularly interested in hearing about content areas of biology that have been modeled, the strengths and weaknesses of those models and modeling techniques used, and to what extent the modeling principles are applicable to other domains.

The precise format will depend on the number and background of interested participants. Participants will be encouraged to develop, present, discuss, merge, and begin the implementation of plans for collaborations and consortia to jointly develop interoperable ontologies for molecular biology. Position papers proposing standards to facilitate ontology interoperation are also encouraged. A more detailed schedule will appear here as it becomes available.
