CfP: KESE09 – deadline extended

June 17th, 2009

kese-kese_logoHello,

due to multiple requests we decided to extend the KESE deadline for submissions to July 1st, 2009.

The 5th workshop on “Knowledge Engineering and Software Engineering” will take place at the 32nd German Conference on Artificial Intelligence in Paderborn this year (Sep 15th, 2009).

We solicit interesting submissions regarding the intersecting field between knowledge engineering and software engineering. Further, we organize a special issue in the International Journal of Knowledge Engineering and Data Mining (IJKEDM) of selected and revised papers. The official call for papers is attached.

Yours, joba

SemWiki09 ROKT!

June 11th, 2009
KnowWE Poster and Demo at the SemWiki09

KnowWE Poster and Demo at the SemWiki09

Last week, Jochen and Joba were representing the ROKT group at the 4th Workshop of Semantic Wikis (SemWiki), that was co-located with the European Semantic Web Conference in Crete.
The workshop was heavily crowded by many people interested in the field – in fact, some people were even sitting on the floor!
The one-day workshop was packed with many intriguing talks in the morning and a poster/demo session in the afternoon. Since a lot of people were presenting their own Semantic Wiki systems (as we did with KnowWE :-) ), the participants wanted to see the systems running in the demo session.

The 1st VIKAMINE Feature Challenge … Results!

June 3rd, 2009
And the oscar goes to ...

And the oscar goes to ...

Dear All,

the first VIKAMINE feature challenge has been completed successfully!
We would like to thank all the contributors for many suggestions and feature requests.

It has been a difficult job to determine the final ranking of the submitted ideas and suggestions. However, the committee of experts has finally decided. The three best proposals selected are:

  1. One-click mode for iterative subgroup-analysis in subpopulations.
    (Volker B.)
  2. Automatic interval-based segmentation of ordinal variables in subgroup mining.
    (Stephanie B.)
  3. Web-service-like loading of a dataset from URL.
    (Alex P.)

Again, we wish to thank all participants, and we look forward to the our next challenge!
Note also, that the first anniversary of VIKAMINE (the VIKAMINE 1.0 release) is coming close, and the next release (VIKAMINE 1.9) is just around the corner!

Happy mining, Martin

Introducing the TextMarker System

May 29th, 2009

The TextMarker system is a rule-based tool for information extraction and text processing tasks. It provides a full-featured development environment based on the DLTK framework and a build process for UIMA Type Systems and generic UIMA Analysis Engines. Different components for rule explanation and test-driven development facilitate the knowledge engineering of rule-based information extraction components.

The basic idea of the TextMarker language can be compared to JAPE: rules match on combinations of predefined types of annotations and create new annotations. Furthermore, the TextMarker language provides an extension mechanism for domain dependent language elements, several scripting functionalities (e.g., for calling other UIMA Analysis Engines) and a dynamic view on the document.

VIKAMINE 1.8 released

May 23rd, 2009
vikamine-181

VIKAMINE 1.8

Today is the VIKAMINE release day, so VIKAMINE 1.8 is now out and available!

Please see the download page for the new version.
* This release includes several bugfixes, and provides new improved features for handling continuous target variables.
* Furthermore, the scalability of the exhaustive optimal discovery methods has been improved significantly using optimistic estimate functions (try the Piatetsky-Shapiro quality function together with SD-Map!).
* Additionally, we have simplified the zoomtable visualization, and have added a novel “introductory” overview visualization for beginners.
* A further feature considers the import of Apache Log data – therefore you can now perform advanced web-log analysis and mining using VIKAMINE as well!

FLAIRS and Back

May 23rd, 2009
FLAIRS-22

FLAIRS-22

Today, the Rokt-Trek came back from the famous FLAIRS Conference, where, for example, ROKT-approaches for textual subgroup mining and quality evaluation and validation of intelligent systems using data mining have been presented.

While the conference provided for a stimulating forum for discussion and further research opportunities, the special track sessions, for example, the DERIS (Design, Evaluation, and Refinement of Intelligent Systems), data mining and case-based reasoning tracks were especially interesting. The poster session also provided for lively and inspiring scientific discussions!

Best, Martin

VIKAMINEing Bibsonomy

May 7th, 2009

bibsonomy VIKAMINE, the versatile visual semantic data mining environment, is now also being applied for social network analysis and community mining!

The ROCKIT special interest group, a subgroup of ROKT, is currently working on social network analysis, community mining, semantic data mining,  text mining and information extraction, sequential mining,  and other advanced knowledge extraction techniques using VIKAMINE.

As we have experienced with respect to our social network analysis application, the VIKAMINE environment is very scalable – even considering rather large amounts of data! Additionally, we have added new exciting features for improving the efficiency even more. These will be available in the new upcoming version that will be available on our usual release day, next on May 23rd.

Happy mining, Martin

KnowWE goes SemWiki

May 4th, 2009

dimensions1_tmb
KnowWE is going to be presented at the Semantic Wiki workshop 2009. The workshop is colocated to the ESWC09 (European Semantic Web Conference) on crete. Our paper entitled “An Extensible Semantic Wiki Architecture” has been accepted as full research paper. It provides a conceptional view on extensiblilty of semantic wikis and further presents the related aspects of KnowWE. For more information have a look at the workshop page.

New KnowWE Logo

Right now the ROCKT group is working heavily on KnowWE development. We are also happy to welcome some new team members. With regard to the first stable release of our Semantic Wiki, that we are looking forward to, we designed a new logo for our System. Thanks to Martina. :-)
