The inventive process has been often modeled as a bounded iterative trial-and-error recombinant search over complex landscape. Our main research question is whether such approximation is empirically valid. To investigate it, we develop a single-industry measure of invention interdependence and provide a relatively direct test of the canonical NK model. Our findings indicate that the NK model co...

Presently, a variety of multimedia information is explosively increasing and many knowledge bases have been built in various areas. It will be necessary to construct and use large-scale knowledge resources in every domain of research. Although various individual knowledge bases already exist, they are not easy to manage, extend and utilize, since they are developed with inconsistent concepts an...

Background and Objectives Increasing grandparent-grandchild interactions have not been targeted as a potential contributing factor to the recent surge in pediatric poisonings. We hypothesized that in grandparents with a young grandchild, a single educational intervention based on the PROTECT "Up & Away" campaign will improve safe medication knowledge and storage at follow-up from baseline. Me...

Several studies have identified clinical questions posed by health care professionals to understand the nature of information needs during clinical practice. To support access to digital information sources, it is necessary to integrate the information needs with a computer system. We have developed a conceptual guidance approach in information retrieval, based on a knowledge base that contains...

Protégé is a successful environment for editing ontologies and knowledge bases. In Protégé, there are several tab-level extensions available to ontology developers, which add to the user-interface of Protégé [4]. However, there are few alternatives for storing ontologies and knowledge bases. Currently, Protégé stores ontologies and knowledge bases as files or tables in relational databases. The...
