The project is a follow up of the MIRO-Web project. The goal of XML-KM is to enhance and use these tools to collect and disseminate knowledge in the extended enterprise. Rule-based XML wrappers fill the warehouse with information from corporate databases, HTML files and office applications. Classical data mining tools, interfaced to the warehouse, will integrate the data and extract further knowledge in the form of derived information and rules. Extended MIRO-Web XML query tools will support subscription and manipulation of desired information on various devices, including PDAs, phones, and faxes.
Adapters capture the required information by applying extraction rules to the selected sources.
The rules are generated semi-automatically from examples provided by a user. Extracted data will be mapped to uniform XML by using concept labels from an ontology. The knowledge mediator suite derives integrated views from the XML sources and object relational tables using algorithms for text min-ing, and concept and knowledge discovery. These are also used to further enrich data via semantic tagging. A limited transaction man-ager supports updates.
