SemIPort Project Overview
| Objective |
| The objective
of the SemIPort project is to develop innovative methods and tools
for creating and maintaining semantic information portals for scientific
communities. |
| Funding Period |
| The SemIPort project began on
July 1st, 2002. It will continue for 3 years, through June 2005. |
| Research Topics |
|
Ontology Modeling and Standards for
Metadata
Ontologies
are central components of a semantic information portal. Hence, one goal
of the SemIPort project is to develop an ontology for a selected scientific
domain.Scalable Storing, Processing, and
Querying of Integrated XML and RDF Data (Knowledge Warehouse)
The knowledge warehouse is the central data repository of the information
portal. It stores and manages information items from different sources
and supports efficient querying and inferencing. XML and RDF are utilized
to create a logical data model which supports the diversified data items
stored in the warehouse.Semantic Web Mining and Knowledge
Integration
Semantic Web Mining aims to improve the results of web mining by exploiting
the new semantic structure in the web. It can be used to (semi)automatically
extend the data repository by adding information items and additional
metadata in order to better fulfill the users' information needs.In addition, users should be able to dynamically integrate new information sources (for example, a website with up-to-date scientific news) into the repository. To this end, SemIPort will provide flexible knowledge integration tools. Data Visualization and Browsing
Interpreting data, discovering structures and relationships
between information items, and indentifying relevant information sets
are difficult tasks if the data repository contains a large number of
entries. To support the user in these tasks, different data-visualization
methods will be explored and implemented.Personalized Interaction
A user's main activities when working with an information
portal are discovering, retrieving, interpreting, managing, and sharing
information items. By maintaining a user model for each user and
utilizing semantic metadata, the portal can provide personalized assistance
for these activities, making the user's interaction with the portal simpler
and more efficient. |
