DAML PI Meeting Status Briefing
OntoAgents
Information Foodchain
| Authoring and Annotation Tool with support for DAML+OIL | ||
| Downloadable from http://annotation.semanticweb.org | ||
| Component-Framework: | ||
| DB-Reverse Plugin | ||
| Ontology-Focused-Crawler Plugin | ||
| Inference Engine designed to handle multiple modeling languages with different semantics | |
| Based on Horn logic with default negation | |
| ASCII & RDF/DAML based syntax | |
| Support for RDF and DAML+OIL (Namespaces, RDF Models) | |
| Part of the RuleML initiative | |
| Implementation based on XSB downloadable from http://triple.semanticweb.org |
Ontology Articulation
and Transformation
| InterDataWorking (structuring of data model transformations) | |||
| Layered approach, based on small reusable transformation components | |||
| Example transforms UML/XMI to RDF Schema | |||
| Similarity Flooding | |||
| determining correspondences in two ontologies | |||
| Pure algorithmic approach to ontology articulation | |||
| Works for graph-based datamodels | |||
| (DAML+OIL, XML Schema) | |||
| Interoperation among autonomous sources | |||
| Deal with stovepipes, within, outside of DoD | |||
| Example: DoD, various commercial transport services | |||
| Approach to interoperation among sources that employ semantically heterogeneous ontologies | |||
| Tools to create articulation ontologies, based on dictionary etc. knowledge | |||
OntoWebber –
Ontology-driven
Portal Design Method & Tools
| Tool-supported ontology-driven website design and creation methodology | ||
| Modeling and compilation approach | ||
| Heterogeneous-data integration & personalization | ||
| Separation of portal perspectives | ||
OntoWebber
–Ontology-driven
Portal Design Method & Tools
| Facilitates ontologies for the domain as well as for website design (Navigation, Content, Presentation) | ||
| Shared infrastructure | ||
| Integrity constraints over website structure as well as the domain | ||
| OntoMat | |||
| Start of SWOBIS, self-updating list of software tools for the semantic web. In collaboration with ISI (web scripter) (see http://tools.semanticweb.org) | |||
| Collaboration with Teknowledge. Integration of OntoMat with Teknowledge markup tools | |||
| Microsoft Word markup | |||
| Extension to Authoring Tool | |||
| Integration of information extraction components | |||
| Annotation Learning | |||
| Text re-recognition | |||
| PDF & Picture Annotation | |||
| OntoWebber | |||
| Larger case-study involving SemanticWeb.org | |||
| Fine Tuning of the representation ontologies and modeling tools | |||
| Ontology Articulation | |||
| Integration with OntoWebber | |||
| Combination of Articulation and Similarity Flooding | |||
| Triple | |||
| development of an efficient inference core (pure Java) | |||
| Extend to mediation system | |||
| for integration with Web Services | |||
| Extended knowledge representation and query facilities for simplifying the tasks of specifying semantics | |||
| explicit negation, path expressions) | |||
| Development of different semantics modules and transformation facilities | |||
| UML to DAML+OIL | |||
| OntoMat – the Annotation Tool | ||
| Cost of manual annotation (time required to annotate information resources) | ||
| Cost of semi-automatic annotation (trained on a given document corpus) | ||
| OntoWebber – Website development | ||
| Cost of conventional website development and maintenance (80%!) | ||
| Triple – Inference Engine | ||
| Cost of building and integrating query and inference facilities for specific data models | ||
| Ontology Articulation | ||
| Cost of manually determining the correspondences among ontologies | ||
| Evaluation involved user studies | ||
| Challenge: So far no standard benchmarks in sight | ||
| Needed to assure scalability to relevant military problems | ||
| Help the scientific community with assessing research progress | ||
| Information Foodchain is the central notation | ||
| Metadata Creation (Annotation Editor) | ||
| Middleware (Inference Engine, Ontology Articulation) | ||
| Application (Portal Generation with OntoWebber) | ||
| Planned Activities include deployment and extension | ||
