Many companies base their business strategy on customized products. To enable a high level of product adaptation in an engineer-to-order approach companies invest time and resources to develop design automation systems. Initially, when implementing a design automation system, the focus is on successfully developing a system that generates design variants based on different customer specificatio...

Personalized knowledge-based systems have not yet become widespread, despite their potential for valuable assistance in many daily tasks. This is due, in part, to the high cost of developing and maintaining customized knowledge bases. The construction of personal assistants as learning apprentices -interactive assistants that learn continually from their users -is one approach which could drama...

General-purpose knowledge bases (KBs) such as YAGO, Wikidata or the Google Knowledge Graph usually contain facts that have a high precision. In contrast, little is known about the recall of such KBs, and anecdotal evidence indicates that knowledge bases have a low recall on many topics. This project aims to develop techniques to evaluate and improve the recall of knowledge bases. We aim to use ...

In this paper, we investigate belief revision in possibilistic logic, which is a weighted logic proposed to deal with incomplete and uncertain information. Existing revision operators in possibilistic logic are restricted in the sense that the input information can only be a formula instead of a possibilistic knowledge base which is a set of weighted formulas. To break this restriction, we cons...

A poorly dcsigncd knowledge base can be as cryptic as an arbitrary program and just as difficult to maintain. Rcprescnting control knowledge abstractly, scparatcly from domain facts and relations, makes the design more transparent and explainable. A body of abstract control knowledge provides a generic framework for constructing knowledge bases for rclatcd problems in other domains and also pro...
