European Symposium on Fuzzy Logic and Technology, EUSFLAT, Bratislava, Slovakia, Sep 20-24, 2021
Another hybrid conference with in-person and online attendance on our part (mainly due to the overlap with the ESTYLF conference which we are organising in Málaga). We presented the works "Closure systems as a fuzzy extension of meet-subsemilattices" (by Emilio Muñoz and other colleagues in the department, Inma P Cabrera presented the paper) and "Approaching the square of oppositions in terms of the f-indexes of inclusion and contradiction" (online presentation by Nicolás Madrid, no screenshot available during his talk).
CMMSE 2021
28/07/21/11:34
Int Conf on Computational and Mathematical Methods in Science and Engineering, CMMSE, Rota, Cádiz, Spain, July 22-27, 2021
As in previous years, we included in CMMSE a special session entitled Mathematical Methods in Computer Science, in cooperation with the Royal Spanish Society of Mathematics. The session was well-attended (mostly by on-site participants together with some online ones). We presented the work "Residuated structures via the f-index of inclusion" and "Topic Modelling in Social Networks with Formal Concept Analysis" (online presentation by Domingo López).
CMMSE'20
02/08/20/10:14
Int Conf on Computational and Mathematical Methods in Science and Engineering, CMMSE, Rota, Cádiz, Spain, July 26-30 2020
Although the original dates were changed due to the COVID-19 outbreak, the conference was finally held at the end of july in Rota (Cádiz), Spain.
As in previous years, we included in CMMSE a special session entitled Mathematical Methods in Computer Science, in cooperation with the Royal Spanish Society of Mathematics. Obviously, the onsite attendance was not as massive as in last edition, however the session was well-attended both by the speakers (all present at the conference) and the online participants. We presented the work "Inconsistency in fuzzy logic systems".
FSTA 2020
04/02/20/13:54
Fuzzy Set Theory and Applications, FSTA 2020
An intense week in Liptovský Ján, Slovakia, full of interaction with other researchers who work in different topics all within the fuzzy umbrella, where we presented the work "Isotone L-fuzzy FCA and categories L-ChuCors and L-Rel".
The next steps on our research line on Galois connections were discussed with Bernard De Baets, and further work on fuzzy mathematical morphology and the F-transform was discussed with Irina Perfilieva, who will be visiting us in some months.
ESCIM'19
09/10/19/13:33
European Symposium on Computational Intelligence and Mathematics (ESCIM). Toledo, Spain, October 2-5, 2019
Just back from a very intense ESCIM'19, a small symposium with a nice working atmosphere.This year it has been held in Toledo, in the old premises of St Pedro Martir and Santa María convents, nowadays in use for the University Castilla-La Mancha.
The first keynote speaker was José Luis (Curro) Verdegay.
Our research team participated with three communications.
Nicolás Madrid presented Some relationships between the notions of f-inclusion and f-contradiction, in which we analyse the relationships between the notions of f-inclusion and f-weak-contradiction, and we present some theoretical results that relate both notions by means of negation operators (used to define complements of fuzzy sets) and Galois connections
Ondrej Krídlo presented On some categories underlying knowledge graphs, in which we propose a method to provide a categorical structure for RDF-based data representing descriptions of entities as a first step towards eventually providing an internal logic which enables to focus on analysis of properties of entities.
Finally, Ángel Mora presented Interactive search by means of the minimal generators, where, we provide a novel lazy algorithm with polynomial delay in which minimal generators are used as forks in a map to guide an interactive search.
EUSFLAT'19

European Conference on Fuzzy Logic and Technology. Prague, September 9-13, 2019
We have attended the conference for presenting two papers, and participating in the Board Meeting of the journal Fuzzy Sets and Systems and the EUSFLAT General Assembly.
As usual, a good conference, very well-attended, with a friendly atmosphere which invites to meet a number of colleagues who work in our and related research topics.
In the picture above, the heads of Lluis Godo, Francesc Esteva and Irina Perfilieva attending our talks in the first seats.

Intl Conf on Computational and Mathematical methods in Science and Engineering. Rota, July 1-5, 2019
Three members of the group attended CMMSE this year, where we organised a special session on "Mathematical Models for Computer Science".
Domingo López (left) presented Recommendations in CDSS using Fuzzy Formal Concept Analysis, and Nicolás Madrid (right) presented Towards a measure of inclusion from the index of inclusion between fuzzy sets.
Last but not least, J.M. Rodríguez (left) presented Analysing patterns in false documents with Formal Concept Analysis to detect forgers, and Manuel Ojeda (right) presented Relational Galois connections between fuzzy t-digraphs.

Intl Conf on Formal Concept Analysis. Frankfurt am Main, June 25-28, 2019
Just come back from ICFCA, where we presented a contributed paper and also participated in a panel about the future of FCA in the BigData era.
See below Prof Baris Sertkaya (conference chair) during the inauguration, and Prof Bernhard Ganter (initiator of the theory of FCA) during his inspiring presentation.
See below a picture during the panel discussion on FCA and BigData, and also the presentation of our paper on relational Galois connections in the AudiMax conference room of the Frankfurt University of Applied Sciences.
