Abstract:

As humans often use both independent positive and negative statements when communicating, adequately dealing with heterogeneous bipolarity has become an important topic in recent research on soft computing in information systems. In the context of database systems, bipolarity can be handled as well at the level of database modelling as at the level of database querying. In this paper, the handling of bipolarity in selection conditions of relational database queries is dealt with. More specifically, it is presented how bipolar satisfaction degrees can be used to model query satisfaction in case of heterogeneous bipolar query specifications. Two modelling approaches of heterogeneous bipolar specifications of user preferences in selection conditions are studied and compared with each other. In the first approach, bipolarity is specified inside elementary selection conditions. In the second approach, bipolarity is handled by considering two independent poles of query conditions, hence reflecting bipolarity at the level between elementary selection conditions.
