Background    (1BJI)

This "Ontology in Knowledge Management and Decision Support (OKMDS)" mini-series is a collaboration between NASA, Ontolog and the (US) Federal Knowledge Management Working Group (KMWG) and is co-organized by a team of individuals from various related communities passionate about creating the opportunity for an inter-community, collaborative exploration of the intersection between Ontology, Knowledge Management and Decision Support, that could eventually lead us toward "Better Decision Making."    (1BJJ)

The mini-series will span a period of about six months (Nov-2007 to May-2008), during which we will be featuring Talks, Panel Discussions and Online Discourse on pertinent issues. We expect all the talks and panel discussion events to be offered in both 'real world' (augmented conference calls) and 'virtual world' (Second Life) settings.    (1BJK)

Title: Organizing Science Knowledge for Discovery    (1BJU)

Abstracts:    (1BJV)

Like many organizations, NASA is challenged with trying to tie together distributed data resources, services, models, and ontologies. NASA meets this challenge with a variety of techniques and this panel discussion will highlight three key approaches in use today. - JeanneHolm    (1BS4)

ScienceOrganizer: A semantics-based Repository for Distributed NASA Science Teams - RichKeller    (1BJW)

ScienceOrganizer is a Web-based collaborative knowledge and content management system developed to support distributed NASA science teams. The system provides a customizable, semantically-structured repository that stores, indexes, and cross-links scientific work products generated by differing groups of collaborating scientists. ScienceOrganizer, which was first made available to users in 2001, was one of the earliest semantic web related applications deployed within NASA. Designed originally to support scientific teams, the system has also been used to support engineering and accident investigation teams, including the Shuttle Columbia Accident Investigation Board. At its core, ScienceOrganizer employs an RDFS-like ontological representation, coupled with simple inference rules. Different parts of the ontology are used to support different project teams, with some portions widely shared across teams. The ontology serves as a basis for organizing content, for driving the user interface, and for maintaining the consistency of the stored work products. Various search mechanisms -- from full-text search through advanced semantic search -- have been implemented as part of the system. ScienceOrganizer supports email distribution lists for project teams, and features an experimental system to recognize semantic content in the email and cross-link it with stored repository content. Through its external API, SScienceOrganizer has been used to interface with scientific equipment, control scientific experiments, and automatically capture data from lab and field experiments. In this talk, I will present an overview of the ScienceOrganizer system, describing some of its features and applications.    (1BJX)

Development of a Community Ontology for Earth System Science - RobRaskin    (1BJY)

An ontology captures and organizes common sense knowledge about a domain to improve discovery and fusion of information resources. In this presentation, we describe our experiences with the development of a second generation ontology - SWEET 2.0 - that will serve as a community standard for Earth system science.    (1BJZ)

The NASA Constellation Program Ontologies - how they are supporting NASA Constellation Program Data Architecture and its applications - RalphHodgson    (1BK0)

The Constellation Data Architecture is a model-based framework that uses the NASA Exploration Initiative Ontology Models (NExIOM) ontologies and an Ontology-Based System of Registries for Metadata and Information Exchange. Building such a Data Architecture and deploying it in large organizations faces a number of challenges. The "alignment challenge" stems from how information across a large enterprise has differing underlying vocabularies and systems of designation. The "acquisition challenge" is the difficulty of acquiring, modeling, and maintaining metadata that is subject to change. The "interoperability challenge" arises from differences in administrative, governance, provenance, and associative metadata in different systems. In this talk, I describe experiences implementing an ontology-based system of registries, how ontologies are used to generate XML Schemas, controlled vocabularies and other work-products for telemetry and commanding. If there is time I will also describe the application of the registries and ontologies in ground support activities for launch control and sequencing at Kennedy Space Center.    (1BK1)

         [Dr. Richard Keller]          [Dr. Robert Raskin]          [Mr. Ralph Hodgson]    (1BS7)

Rich Keller is technical lead for the Information Sharing and Integration Group within the Intelligent Systems Division at NASA Ames Research Center. For over 15 years, Keller has managed NASA research and development projects in the areas of intelligent information management and collaborative systems. He has been the principal investigator on several long-term projects with successful NASA deployments in engineering, aviation, and scientific domains. His software applications in the areas of knowledge management for distributed science and engineering workgroups and data integration for aviation safety are the subject of multiple patent applications and have resulted in successful commercial spin-offs. Keller has developed decision and work support systems for a wide range of NASA personnel, including astrobiologists, space and earth scientists, accident investigators, and air traffic safety managers. His current focus is on the development of intelligent search tools for International Space Station flight controllers. Prior to NASA, Keller worked as a research associate at Stanford University¬ís Knowledge Systems Laboratory in the areas of model-based reasoning and large-scale knowledge base development. Dr. Keller¬ís areas of expertise include artificial intelligence and semantic technologies, knowledge management, indexing and search systems, machine learning and knowledge acquisition, digital libraries, and collaborative systems.    (1BS8)

Rob Raskin is Supervisor of the Data System Engineering Group in the JPL Instrument Software and Science Data Systems Section. He is PI of the Semantic Web for Earth and Environmental Terminology (SWEET) project to develop an upper-level ontology for Earth system science. He is Vice-President of the Earth Science Information Partner (ESIP) Federation. He holds a Ph.D. in Atmospheric Science from the University of Michigan.    (1BS9)

Ralph Hodgson is a co-founder and the CTO of TopQuadrant, Inc., a US-based company that specializes in semantic technology consulting, training, and tools. He combines expertise in semantic technologies with over 25 years of experience in business application development and deployment, consulting, software development, and strategic planning. Prior to starting TopQuadrant in 2001, he held executive consulting positions at IBM Global Services where he was a founding member of Portal Practice and Object Technology Practice. Prior to IBM, he was European Technology Director, founder, and Managing Director of Interactive Development Environments, which was an international CASE tools vendor. Between 1996 and 2000, he organized the OOPSLA workshops on "System Envisioning." He is a published author and a frequent speaker at conferences. Recent books he has co-authored are Adaptive Information, published by John Wiley in 2004, and Capability Cases: A Solution Envisioning Approach, published by Addison-Wesley in July 2005.    (1BSA)
