Technology-oriented companies are typically interested in monitoring developments concerning their technologies. However, most companies, especially SMEs, don’t have an efficient process how this is achieved. If at all, efforts are mostly limited to uncoordinated keyword queries on web resources. Here, we present a semi-automatic approach that allows for structured and continuous detection of r...

KnowItAll [4], and others have successfully constructed semantic knowledge bases of large scale. Factual knowledge is typically represented in RDF, the W3C standard for Semantic-Web contents. RDF data can be seen as a graph whose nodes are entities These knowledge bases can be queried using the W3C-endorsed SPARQL [33] language. Yet, a knowledge base about entities can never be fully complete o...

Cognitive flexibility is defined as the ability to assimilate previously learned information and concepts to generate novel solutions to new problems. This skill is crucial for success within ill-structured domains such as biology, physiology, and medicine, where many concepts are simultaneously required for understanding a complex problem, yet the problem consists of patterns or combinations o...

A capacity for analogy is an excellent acid test for the quality of a knowledge-base. A good knowledge-base should be balanced and coherent, so that its high-level generalities are systematically reflected in a variety of lower-level specializations. As such, we can expect a rich, well-structured knowledge-base to support a greater diversity of analogies than one that is imbalanced, disjoint or...

One approach to integrating knowledge bases is based on nding assertions that relate the expressions in the constituent terminologies. For knowledge bases with many terms this task requires computer support. We set up a formal framework for merging Description Logic TBoxes, and then explore the limits of a purely structural approach to the problem of nding interrelationships between knowledge b...

In this paper a knowledge base structure to support multiple view generation over a federation of loosely-coupled heterogeneous databases available over a computer network is described. In such a federation user information requirements change and evolve as their awareness of the contents of the federation improves. This means that users need diierent integrating views if they are to realise th...

In this work, we outline an approach to incrementally building knowledge-based systems based on tightly controlling the order of evaluation of the knowledge components of the system. The order of evaluation is based on two relations, sequence and correction, that correspond to two kinds of changes that an expert may wish to make to a knowledge base. A consistency notion based on past performanc...
