Special Session on Rough and Fuzzy Similarity Modelling Tools
Written by Lukasz Sosnowski   

IPMU 2018

17th International Conference on Information Processing and Management of Uncertainty in Knowledge-Based Systems. Cádiz, Spain, June 11th – 15th


Special Session on Rough and Fuzzy Similarity Modelling Tools

For centuries the concept and properties of similarity has been the subject of study and a
vehicle for establishing and describing the existing relations between objects. Beginning with Plato
who considered it in the form of "analogy", the notion of similarity manifested itself throughout the
development of philosophical investigations regarding reasoning. Nowadays it plays an ever-increasing
role in describing and understanding reasoning and cognition. Similarity that binds entities
in an approximate, imprecise way is in the core of soft and granular methods of computing.
There are studies on numerous approaches to modelling, expressing and utilizing similarity
relations within the widely understood area of soft computing. In rough sets, modelling similarity
is essential for both standard approaches and extensions concerning the analysis of complex
data. Analogously, fuzzy systems strongly relate to modeling of similarities as well. Numerous applications
of rough and fuzzy sets in the fields of information processing, decision support, recommendation
and others testify to the importance and usefulness of similarity-based tools.
In the proposed special session, we intend to bring together researchers whose work corresponds
to similarity modelling and handling, in particular with a use of rough and fuzzy approaches.
The overall goal is to collect and review various methods for modelling similarity and scenarios of
their application.
Topics include but are not limited to:

  •  Rough sets and their extensions
  • Tolerance and neighborhood models
  • Similarity in granular computing
  •  Fuzzy rough sets
  •  Fuzzy similarity
  •  Similarity modelling tools
  • Tversky's contrast model
  •  Ontology-based similarities
  •  Similarities in hierarchical systems
  •  Similarity aggregations
  •  Applications of similarity models
  •  Similarity in data clustering
  •  Similarity-based reasoning
  •  Similarity in decision support systems
  •  Similarity in recommendation systems
  •  Similarity in three-way decision-making

IJCRS'2018 International Joint Conference on Rough Sets
Written by Lukasz Sosnowski   


International Joint Conference on Rough Sets 

20-24, August, 2018
ICISE - International Centre for
Interdisciplinary Science & Education,
Quy nhon, Vietnam


IJCRS is the prime international conference sponsored by the International Rough Set Society (IRSS). IJCRS 2018 encapsulates four main tracks which refer to major threads of rough set conferences held so far:

  • Rough Sets and Data Science
    (in relation to RSCTC series organized since 1998)

  • Rough Sets and Granular Computing
    (in relation to RSFDGrC series organized since 1999)

  • Rough Sets and Knowledge Technology
    (in relation to RSKT series organized since 2006)

  • Rough Sets and Intelligent Systems
    (in relation to RSEISP series organized since 2007)

Paper submission

The authors are cordially invited either to submit regular research papers (10-15 pages long) or short papers (6 up to 8 pages long) formatted in Springer llncs style. Each paper will be reviewed by three reviewers, members of the Program Committee, and accepted papers will be published in Springer’s LNAI series of Proceedings, indexed in Web of Science. 

The authors of best papers will be invited to extend and submit them to selected international scientific journals.

Important dates

Regular paper submission deadline: March 10, 2018;

Short paper submission deadline: April 1, 2018;

Acceptance Notification: May 6, 2018;

Final Version submission deadline: May 20, 2018;
