Financial literacy and psychological disaster preparedness: applicability of approach based on fuzzy functional dependencies
2022, Information Processing and ManagementCitation Excerpt :These two approaches should not be considered as rivals, but rather as complementary approaches in explaining emotions in an emergency situation related to financial literacy. The concept of LSs is a mature one (introduced by Yager (1982) and for LSs with restriction by Rasmussen and Yager (1997). Since then, the theory of LSs has been improved and broadly applied in a variety of fields.
Expression and efficient evaluation of fuzzy quantified structural queries to fuzzy graph databases
2019, Fuzzy Sets and SystemsInterpretability of fuzzy linguistic summaries This work is dedicated to Francesc Esteva, for his pioneering work in fuzzy logic and his dedication to the fuzzy community, especially in Europe
2016, Fuzzy Sets and SystemsCitation Excerpt :It must be underlined that this approach does not generate all relevant sentences but checks the validity of some sentences queried by the user. FQuery [26], SummarySQL [27] or Quantirius [28] are instances of this approach. The computation complexity with these systems depends on the level of freedom in the query.
Fuzzy quantification: A state of the art
2014, Fuzzy Sets and SystemsCitation Excerpt :A simple example in this field using soft database queries is also provided in [90]. Some works developed a fuzzy query language called SummarySQL to let linguistic summaries be a part of the fuzzy queries, and then evaluate the summary by means of a validity measure [68,69]. In [5] it is developed a method for giving a linguistic summary of a numerical attribute involved in a fuzzy query.
Integration of data selection and classification by fuzzy logic
2012, Expert Systems with ApplicationsCitation Excerpt :Although the SQL is a very powerful tool, it is unable to satisfy needs for data selection based on linguistic terms (vague predicates such as altitude near 200 m, high length of roads) and degrees of matching query conditions. To overcome this imperfection different approaches based on fuzzy logic have been proposed and many fuzzy query implementations have been designed, e.g. Kacprzyk and Zadrożny (1995), Rasmussen and Yager (1997), Bosc and Pivert (2000) and Wang, Lee, and Chen (2007). In order to bring benefit of the fuzzy logic to users and to make easy to use the querying tool, the fuzzy Generalized Logical Condition (GLC) capable to implement linguistic terms into the where part of the SQL has been created and described in Hudec (2009).
A functional interpretation of linguistic summaries of data
2012, Information SciencesCitation Excerpt :Section 3.3 stresses the needs for a new type of linguistic summaries, still in the form of a natural language sentence. The linguistic summaries proposed by Yager and co-workers [20–22,24,27] are quantified statements of type “Q X are A” or “Q B X are A” where Q is a linguistic quantifier [31], A and B are two gradual predicates defined by fuzzy sets. When dealing with relational databases, the crisp set X is a set of rows coming from the database (a relation from the database).
