Computer Assisted Surgery seeks data from various sources related to surgical knowledge, which is mostly represented in the form of discrete databases. However, databases serve as data storage mechanism rather than knowledge representation system. As CAS is becoming more common for various types of surgical interventions, there is a need for representation, storage and processing of surgical kn...

Object bases underlying knowledge-based applications tend to be complex and require management. This research aims at improving the performance of object bases underlying a class of large knowledge-based systems that utilize object-oriented technology to engineer the knowledge base. In this paper, a hybrid clustering strategy that beneecially combines semantic clustering and iterative graph-par...

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...

Introduction: Today, transmitted diseases through food and food poisoning have been considered as a public health problem in many countries. Lack of knowledge concerning hygiene and food safety can increase the risks associated with the consumed foods. Hence, the present study aimed to determine the students' knowledge and attitude of hygiene and food safety in Shahid Sadoughi University of Med...

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...

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...

thesaurus is one, out of many, precious tool in information technology by which information specialists can optimize storage and retrieval of documents in scientific databases and on the web. in recent years, there has been a shift from thesaurus to ontology by downgrading thesaurus in favor of ontology. it is because thesaurus cannot meet the needs of information management because it cannot c...

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...
