Bipolar Fuzzy Querying of Temporal Databases
نویسندگان
چکیده
Temporal databases handle temporal aspects of the objects they describe with an eye to maintaining consistency regarding these temporal aspects. Several techniques have allowed these temporal aspects, along with the regular aspects of the objects, to be defined and queried in an imprecise way. In this paper, a new technique is proposed, which allows using both positive and negative -possibly impreciseinformation in querying relational temporal databases. The technique is discussed and the issues which arise are dealt with in a consistent way.

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...
متن کاملFTSQL2: Fuzzy time in relational databases
2 Fuzzy Database with FSQL FSQL language is an extension of the SQL language which permits us to write flexible (or fuzzy) conditions in our queries to a fuzzy or traditional database. In this work we present some new fuzzy data types based on time concepts. We extend the existing temporal data types in SQL2 and we give a brief overview of basic definitions in fuzzy temporal databases. In parti...
متن کاملRemarks on a Fuzzy Approach to Flexible Database Querying, Its Extension and Relation to Data Mining and Summarization
For an effective and efficient information search of databases, various issues should be solved. A very important one, though still usually neglected by traditional database management systems, is related to a proper representation of user preferences and intentions, and then their representation in querying languages. In many scenarios, they are not clear-cut, and often have their original for...
متن کاملSpatio-Temporal Querying in Video Databases
In this paper a video data model that allows efficient and effective representation and querying of spatio-temporal properties of objects is presented. The data model is focused on the semantic content of video streams. Objects, events, activities performed by objects are main interests of the model. The model supports fuzzy spatial queries including querying spatial relationships between objec...
متن کاملBipolar SQLf: A Flexible Querying Language for Relational Databases
Flexible querying of information systems allows expressing complex preferences in user queries. Such preferences can be modeled by fuzzy bipolar conditions which are made of constraints c and wishes w and interpreted as ”to satisfy c and if possible to satisfy w”.We define in this article the main elements of the Bipolar SQLf language, which is an SQL-like querying language based on a bipolar r...
