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...

We advance a model of human probability judgment and apply it to the design of an extrapolation algorithm. Such an algorithm examines a person's judgment about the likelihood of various statements and is then able to predict the same person's judgments about new statements. The algorithm is tested against judgments produced by thirty undergraduates asked to assign probabilities to statements ab...

Two experiments compared people’s interpretations of indicative conditionals (e.g., if the shape is blue, then it’s a square), subjunctive conditionals (e.g., if the shape were blue, then it would be a square), causation statements (e.g., the shape being blue causes it to be a square) and prevention statements (e.g., the shape being blue prevents it from being a square). In the first experiment...

Dublin Core as a Language. Dublin Core is often presented as a modern form of catalog card -a set of elements (and now qualifiers) that describe resources in a complete package. Sometimes it is proposed as an exchange format for sharing records among multiple collections. The founding principle that "every element is optional and repeatable" reinforces the notion that a Dublin Core description ...

Code clone detection is an important area of research as reusability is a key factor in software evolution. Duplicate code degrades the design and structure of software and software qualities like readability, changeability, maintainability. Code clone increases the maintenance cost as incorrect changes in copied code may lead to more errors. In this paper we address structural code similarity ...
