From Data Mining to Text Mining. Is consideration of background knowledge in the mining process possible?

 

In this talk we will give an overview about application of Data and Text Mining in industry and business and discuss the problem of consideration of background knowledge in the mining process from a practical point of view.

Ontology-Based Query and Answering in Chemistry: OntoNova @ Project Halo
 
The Project Halo has the long-term objective of developing a Digital Aristotle, i.e. a knowledge system that is able to answer questions in a particular domain and give explanations for its answers. In this talk it is reported about the Ontoprise contribution to the Halo Pilot Project, in which various competing ontology engineering methodologies and knowledge system capabilities have been investigated. Concerning the first, I'll describe how we dealt with engineering a significant set of laws from chemistry that we had to let interact at different levels of generality and in varying orders. With regard to the latter, I'll report on the ability of our system to produce coherent and concise explanations of its reasoning. The importance of these two aspects can hardly be underestimated in the Semantic Web, as with future growth the interaction of large sets of laws will require dedicated management as well as the ability to let the user explore the trustworthiness of the ontology and the underlying data sources.

Wrap-up discussion

 

 

Topic and Motivation

 

 

The workshop is concerned with the interaction between prior knowledge as encoded in ontologies and derived knowledge as obtained by a knowledge discovery process.

 

The use of prior knowledge may significantly enhance knowledge discovery from large datasets or text collections. Currently, in most KDD projects, prior knowledge is only present implicitly (in the head of the human analyst) or in the form of textual documentation. Even in knowledge-intensive approaches such as ILP, the background knowledge is often not organized around a well-formed conceptual model. This practice seems to ignore latest developments in knowledge engineering, where domain knowledge is typically defined by formal ontologies.

 

Ontologies are formal, explicit specifications of shared conceptualizations of a given domain of discourse. The expected central role of ontologies in the organization and functioning of the Semantic Web has been well documented in recent years. Somewhat less traditional is the role of ontologies in incremental approaches to knowledge discovery, in which ontologies and machine learning methods are used in combination to mine, interpret and (re-)organise knowledge.

 

While knowledge engineering research has already recognised the value of knowledge discovery from textual and semi-structured resources in the process of building an ontology (i.e. in ontology learning), links in the opposite direction are more rare. Within the context of this workshop we intend to bring together researchers from both directions in order to initiate a discussion on how to integrate insights from both communities.

 

 

Areas of Interest

 

Submissions are invited on all aspects of the interaction between Knowledge Discovery (KDD) and Ontologies (Onto):

 

*  Onto4KDD

-

domain ontologies for extending source data and/or to constrain the search for hypotheses

-

ontologies of the knowledge discovery domain to recommend and/or configure methods or tools for a given problem

*  KDD4Onto

-

knowledge discovery (from databases, semi-structured data, text, multimedia) in ontology learning (extension/evolution) and/or ontology mapping (merging/integration)

*  Onto4KDD & KDD4Onto

-

combinations of knowledge discovery and ontologies to cover the full knowledge life cycle, i.e. the use of ontologies in incremental knowledge discovery experiments (based on previous results)

*  Usability & Evaluation

-

practical applications in industry of (the interaction of) knowledge discovery and ontologies

-

evaluation methodologies for (the interaction of) knowledge discovery and ontologies
