Projects
Accompanying my theoretical research, there are two projects I mainly work for:
Conexp-Clj — Scale-Exploration Standalone
Accompanying our research on conceptual measurements, we implemented the exploration of scale-measures algorithm in conexp-cjl and provided a standalone (Ready for Use) version of the algorithm. Associated Papers:
- Hanika T., Hirth J.: Exploring Scale-Measures of Data Sets submitted.
- Hanika T., Hirth J.: On the Lattice of Conceptual Measurements submitted.
Conexp-Clj — A Research Tool for FCA
The research unit Knowledge & Data Engineering continues the development of the research tool conexp-clj, originally created by Dr. Daniel Borchmann. The continuous enhancement of the software package is supervised by Dr. Tom Hanika. Having such a tool at hand, the research group is able to test and analyze the theoretical research efforts in the realm of formal concept analysis and related fields. The most recent, pre-compiled, release candidate can be downloaded here.
A presentation of the tool can be found in Conexp-Clj – A Research Tool for FCA
BibSonomy
BibSonomy is a scholarly social bookmarking system where researchers manage their collections of publications and web pages. BibSonomy is an open source project, continously developed by researchers in Kassel, Würzburg, and Hanover. Functioning as a test bed for recommendation and ranking algorithms, as well as through the publicly available datasets, containing traces of user behavior on the Web, BibSonomy has been the subject of various scientific studies.
