Natural Language Processing (NLP) is rapidly increasing in all domains of knowledge acquisition to facilitate different language user. It required develop based NLP systems provide better results. Knowledge can be implemented using ontologies where ontology a collection terms and concepts arranged taxonomically. The that are visualized graphically more understandable than the text form. In this...

A major step in building guideline-based clinical care systems is encoding medical knowledge in guideline documents for interpretation by the computer. Guideline models provide the structure to encapsulate guideline knowledge. Developers who are familiar with the guideline model and domain experts who have relevant medical knowledge work as a team to encode guidelines using knowledge acquisitio...

Article history: Received 5 May 2014 This study examines the motives mentors have for providing developmental support to their protégés. Based on qualitative interviewswith 20 informalmentors, we show five broad categories of mentor motives: self-focused motives (based on individual reasons), protégé-focused motives (directed at the protégé), relationship-focused motives (directed at the relati...

We present an extension of the existing Protégé system that supports collaborative ontology editing. The extended system—Collaborative Protégé—is currently available as a prototype. In addition to the common ontology editing operations, it enables annotation of both ontology components and ontology changes. It supports the searching and filtering of user annotations based on different criteria....

Mentors rarely receive education about the unique needs of underrepresented scholars in the biomedical and behavioral sciences. We hypothesized that mentor-training and peer-mentoring interventions for these scholars would enrich the perceived quality and breadth of discussions between mentor-protégé dyads (i.e., mentor-protégé pairs). Our multicenter, randomized study of 150 underrepresented s...

A frame-based knowledge base can be a very large network whose information content is difficult for developers and users to comprehend and manipulate. In the SAGE consortium that is creating the technological infrastructure required in developing enterprise clinical decision-support systems for guideline-based care, knowledge engineers and clinicians must collaborate to develop knowledge bases ...

Ontology play a key role in information exchange, use and re-using knowledge, shared and common understanding of a domain that can be communicated between people and across application systems which is the goal of semantic web. Ontology may be described as sharable conceptualization of a specific domain of interest in a machine-understandable format. Therefore, Ontology design and development i...

In Ontology Based Data Access (OBDA), the aim is to use an ontology to mediate access to data. The main contribution of this work is to demonstrate two key components of an OBDA system, whose combination allows ontology practitioners to finally realize end-to-end OBDA systems. The first component is an OBDA-enabled reasoner, named DIG-MASTRO. The second component is the OBDA Plugin for Protégé,...
