A Multi-Objective Anytime Rule Mining System to Ease Iterative Feedback from Domain Experts [article]

Tobias Baum and Steffen Herbold and Kurt Schneider
2018 arXiv   pre-print
To overcome these problems, we take a holistic approach and develop a rule mining system that simplifies iterative feedback from domain experts and can easily incorporate the domain-specific evaluation  ...  A central part of the system is a novel multi-objective anytime rule mining algorithm. The algorithm is based on the GRASP-PR meta-heuristic but extends it with ideas from several other approaches.  ...  An essential part of this system is a rule mining algorithm, but it also contains other features to ease iterative collaboration between the system and human domain experts.  ...

GIMO : A multi-objective anytime rule mining system to ease iterative feedback from domain experts [article]

Tobias Baum, Steffen Herbold, Kurt Schneider, University, My
2021
To overcome these problems, we take a holistic approach and develop a rule mining system that simplifies iterative feedback from domain experts and can incorporate the domain-specific evaluation needs.  ...  A central part of the system is a novel multi-objective anytime rule mining algorithm. The algorithm is based on the GRASP-PR meta-heuristic but extends it with ideas from several other approaches.  ...  The user rarely needs to wait for the system, and neither does the system need to wait for the user. • Geared towards domain expert feedback, i.e., the user can provide feedback without the need to translate  ...

Expressive modeling for trusted big data analytics: techniques and applications in sentiment analysis

Erik Tromp, Mykola Pechenizkiy, Mohamed Medhat Gaber
2017 Big Data Analytics  
The necessity to collect lots of labeled data from a particular domain is another obstacle. Therefore, in industry rather simplistic approaches are adopted resulting potentially in poor accuracy.  ...  The latter affects the possibility of adapting such sentiment analysis approaches to a certain domain of interest and results in either poor performance or high maintenance overhead.  ...  Datasets used in the paper are diverse and collected over a number of years. Some of the datasets will be made available in the near future, to allow reproducibility of the results.  ...
