چکیده

In [1, 2] we studied various concepts of bipolar queries (cf. Dubois and Prade [3]). We advocated there the use of a fuzzified version of the original crisp definition introduced by Lacroix and Lavency [4]. However, the fuzzification proposed, as general as it was, leaves open the choice of a representation of logical entities, notably the logical connectives and quantifiers. In the present paper we study the influence of the choice some representations that are popular in fuzzy logic on matching degrees of the tuples and their resulting ordering.

Bipolar Queries: An Approach and its Various Interpretations

The concept of a bipolar query is studied in the framework of the flexible fuzzy querying of databases. The focus is on the aggregation of the negative and positive conditions forming a bipolar query. Three formal logical representations of such an aggregation are proposed and analyzed taking into account various possible interpretations of fuzzy logical connectives. The relation to other appro...

A survey on di erent triangular norm - basedfuzzy

Among various approaches to fuzzy logics, we have chosen two of them, which are built up in a similar way. Although starting from diierent basic logical connectives, they both use interpretations based on Frank t-norms. Diierent interpretations of the implication lead to diierent axiomatizations, but most logics studied here are complete. We compare the properties, advantages and disadvantages ...

Query expansion using wordnet with a logical model of information retrieval

This paper describes the experimentation conducted to test the effectiveness of query expansion within the logical model PLBR. We ran different experiments generating queries as logical formulas with different connectives, and using different types of linguistic information extracted from WordNet. Results show that lexical expansion is not able to improve retrieval performance. Nevertheless, th...

The Semantics and Pragmatics of Logical Connectives: Adults' and Children's Interpretations of And and Or in a Guessing Game

The development of the ubiquitous logical connectives and and or provides a window into the role of semantics and pragmatics in children’s linguistic development. Previous research has suggested that adults and children might differ in their interpretation of or in two ways. First, unlike adults, children might interpret or as logical conjunction, akin to and. Second, children might interpret o...

Logics for Databases and Information Systems

Temporal logic is obtained by adding temporal connectives to a logic language. Explicit references to time are hidden inside the temporal connectives. Different variants of temporal logic use different sets of such connectives. In this chapter, we survey the fundamental varieties of temporal logic and describe their applications in information systems. Several features of temporal logic make it...
