The RuZA workshop (RuZA2015) was an international Russian-South African workshop on applications of Formal Concept Analysis in Computer Science and Data Analysis. All of the contributed research papers reported on research where models based on Formal Concept Analysis were extensively used. Formal concept analysis (FCA) is a branch of lattice theory motivated by the need for a clear formalization of the notions of concept and conceptual hierarchy. It has been successfully used for conceptual clustering and association-rule mining. We believe that formal concept analysis and its extensions can contribute to the analysis and mining of social networks, text mining, modelling processes, and political studies, among other fields. The objective of the RuZA workshop was to bring together researchers and practitioners to discuss the ways FCA can be used in various applications related to these domains. The workshop program included an introductory talk ”Towards Efficient, Real-time Pocket Data Mining: Current Trends and Open Challenges” given by Herna L. Viktor from School of Electrical Engineering and Computer Science, University of Ottawa, as well as regular talks followed by a panel discussions. The proceedings of RuZA workshop include seven papers that were reviewed by at least two reviewers. We would like to thank all the authors for their contributions and the organizers of RuZA 2015 for their kind support in hosting the workshop. Our warm thanks go also to the reviewers for their careful review of the submissions and their useful comments and suggestions. Finally, we would like to thank Russian foundation for Basic Research (grant no. 14-01-93960) and National Research Foundation of South Africa (grant no. 92187) for financial support of research collaboration and organization of the workshop.

Collaborative Conceptual Exploration as a Tool for Crowdsourcing Domain Ontologies

Объедков С. А., Ромашкин Н. С., , in: RuZA 2015 Workshop. Proceedings of Russian and South African Workshop on Knowledge Discovery Techniques Based on Formal Concept Analysis (RuZA 2015). November 30 - December 5, 2015, Stellenbosch, South AfricaVol. 1552.: Aachen: CEUR Workshop Proceedings, 2015. P. 58–70.

Domain ontologies are essential in disciplines as diverse as software engineering, medicine, or political science to name just a few. This paper describes an ongoing effort to develop a methodology for collaborative ontology construction by geographically spread communities of experts and implement a web-based prototype supporting this methodology. A distinctive feature of the proposed approach ...

Full-text Search in Intermediate Data Storage of FCART

Незнанов А. А., Паринов А. А., , in: RuZA 2015 Workshop. Proceedings of Russian and South African Workshop on Knowledge Discovery Techniques Based on Formal Concept Analysis (RuZA 2015). November 30 - December 5, 2015, Stellenbosch, South AfricaVol. 1552.: Aachen: CEUR Workshop Proceedings, 2015.

The speed of full-text search directly affects the process of text analysis. Search engine creates a text index, which is used for fast full-text search. Solr and ElasticSearch are two popular search engines. A text analysis system requires fast implementing searching and indexing at the same time. This paper describes preprocessing workflow of the analysis ...

Towards a Unified Taxonomy of Biclustering Methods

Игнатов Д. И., Watson B., , in: RuZA 2015 Workshop. Proceedings of Russian and South African Workshop on Knowledge Discovery Techniques Based on Formal Concept Analysis (RuZA 2015). November 30 - December 5, 2015, Stellenbosch, South AfricaVol. 1552.: Aachen: CEUR Workshop Proceedings, 2015.

Being an unsupervised machine learning and data mining technique, biclustering and its multimodal extensions are becoming popular tools for analysing object-attribute data in different domains. Apart from conventional clustering techniques, biclustering is searching for homogeneous groups of objects while keeping their common description, e.g., in binary setting, their shared attributes. In bioinformatics, biclustering is used ...
