We propose in this paper an approach to learn term to concept mapping with the joint utilization of verb relations and an existing ontology. This is a non-supervised solution that can be applied to any field for which an ontology modeling verbs as relations holding between the concepts was already created. Conceptual graphs, representing a set of verb relations, are learned from a natural langu...

A method of mapping sets of uninterpreted record or relation schemes into entity-relationship diagrams is described and then applied to two conceptual design problems. First, the method is applied to the design of relational databases. It is shown that the method can be interpreted as a normalization procedure that maps a given relational schema into a new schema that represents an entity-relat...

Background and our research goal Divergent exploration of an ontology Background ■Ontology: It is important that the ontology captures the essential conceptual structure of the target world as generally as possible. ■Domain experts often want to understand the target world from the domain-specific viewpoints in which they are interested. In many cases their interests are different, even if they...

Prior work supports the pedagogical value of conceptual maps for offering students an overview of a topic as well as the connections between subtopics. In this poster we describe a system that uses automated topic modeling technology to map the topics and sub-topics in a collection of documents. An interactive graphical representation allows users to explore this topic analysis, using it as an ...

BACKGROUND In recent years, interventions and health policy programmes have been established to promote patient empowerment, with a particular focus on patients affected by long-term conditions. However, a clear definition of patient empowerment is lacking, making it difficult to assess effectiveness of interventions designed to promote it. The aim in this study was to develop a conceptual map ...

This poster reports on current work with the NSF-funded Achievement Standards Network (ASN) to support discovery of educational resources in digital libraries using conceptual graphs of officially promulgated achievement standards statements. Conceptual graphs or knowledge maps of achievement standards reveal the macrostructure of the learning domain modeled by those standards and support highe...

Conceptual maps have been used in many areas as a means of capturing and representing knowledge. Several authors have explored the use of visual tools to enhance the learning process. Thinking maps as well as frame games use visual patterns of relationships (learners thinking processes) to structure knowledge. Based on their graphical structure it is possible to recognize the thinking process(e...
