SEMANTIC WEB MINING

                            in conjunction with the
   12th European Conference on Machine Learning (ECML'01)
       5th European Conference on Principles and Practice
          of Knowledge Discovery in Databases (PKDD'01)
               September 3-7, 2001, Freiburg, Germany

                              --- Call for Papers ---


The workshop aims to bring together researchers and practitioners 
from the two fastly developing research areas Semantic Web and 
Web Mining. One can improve the results of Web Mining by 
exploiting the new semantic structures in the web. Furthermore, Web 
Mining can help to build the Semantic Web. 

The Semantic Web is based on a vision of Tim Berners-Lee. He 
suggests to enrich the web by machine processable information 
which is organized on different levels (see 
www.w3.org/DesignIssues/Semantic.html). For Web Mining, the 
levels from XML and RDF to ontologies and logics are of particular 
interest. Web Mining applies data mining techniques on the web. 
Three areas can be distinguished: Web usage mining analyzes the 
user behavior, web structure mining explores the hyperlink structure, 
and web content mining exploits the contents of the documents in 
the web. 

In the workshop, we want to discuss the use of XML, RDF, 
ontologies, and logics for the three web mining areas; and the 
support of web mining techniques for building (XML and RDF) 
schemes and ontologies. There are quite a number of people from 
different communities that approach the field of Semantic Web 
Mining from different, interesting angles. The goal of the workshop is 
to establish communiction between these communities. 


Topics of interest include, but are not limited to: 
- Concept Taxonomies (e.g. product hierarchies) and Web Mining 
- Using the Syntactic Layer (XML) for Semantic Web Mining 
- Using the Vocabulary Layer (e.g. RDF-Schema) for 
  Semantic Web Mining 
- Using the Logical Layer (e.g. Description Logics/OIL) for 
  Semantic Web Mining 
- User Profiling, Segmentation and Interpretation with 
  Background Knowledge 
- Using Background Knowledge for Web Mining 
- Metadata-based Text Mining 
- Text Mining for Creating Metadata 
- Learning Taxonomies and Ontologies from the Web 
- Metadata Harvesting 
- Information Extraction with Machine Learning 

We invite contributions that advance the state-of-the-art in topics 
related to the purpose of the workshop. Persons interested in 
participating should submit either a technical paper (less than 6000
words) or a position paper (less than 1500 words) addressing new 
research issues. In addition, we solicit proposals for panel 
discussions. Submit before June 8, 2001 in electronic form (strongly 
preferred!) in postscript or pdf to: hotho@aifb.uni-karlsruhe.de. 
Although not required for the initial submission, we recommend to 
use the IJCAI 2001 style (http://ijcai.org/data/), as this will be the 
required format for accepted papers. 

Alternatively, printed copies can be sent to: 
Andreas Hotho 
Institute AIFB 
University of Karlsruhe

People who want to attend the workshop have to be registered to the 
main conference ECML/PKDD-2001. Workshop proceedings will be 
distributed among registered participants at the workshop. The 
conference will probably provide a joint paper style for the 
proceedings. In addition, there will be a joint Web-publication of all 
the workshop proceedings after the
conference. Hence, electronic submissions to the workshops are 
strongly encouraged. 


Schedule 

Deadline for paper submission: 8 June 2001 
Notification of acceptance: 29 June 2001 
Deadline for final contributions: 13 July 2001
