Vision of Semantic Web

• The Semantic Web is a mesh of information linked up in such a way as to be easily processable by machines, on a global scale. You can think of it as being an efficient way of representing data on the World Wide Web, or as a globally linked database.

(Source: http://infomesh.net/2001/swintro/ - The Semantic Web: An Introduction)

Vision of Semantic Organization

• To have all information and data available for computer processing via Semantic Web technology (XML, RDF, OWL)

• Ontology translation not so important on one domain …

• Document and Text analysis results using Semantic annotation are part of this

• Conversion or mapping of RDBMS to XML/RDF/OWL is another problem

Ontology

• Unique URI of concepts/objects

• Related to:– Trees– Graphs– Object database structure– Rules– Logic formulas

• Inference• Reasoning

HTML => XML => RDF => DAML+OIL => OWL

OWL-DL <=> Description Logic

Email in Organizations

• Email – action oriented• Asynchronous• Context sensitive

• e-mail infrastructure in every organization• communication in a modern organization

is over 78% action oriented• Workers interact with their e-mail systems

on a daily basis

Innovation

• The central role of emails – Ubiquitous, Linked to business processes

• Tying email content to business context, so as to analyze and understand the current context and relate it to knowledge in the organizational memory.

• A use of email enables to have an “active” knowledge sharing channel, since a user does not have to search extensively for needed knowledge. Shared knowledge is delivered within the email – the current problem/activity being solved by the user.

EMBET

• Knowledge and information management

• For ontological context relevant hints/notes are returned

Ontology based Text Annotation - OnTeA

• Detecting Meta data from Text• Preparing improved structured

data for later computer processing• Structured data are based on application

ontology model

• Pattern based approach + IR using regular expressions
