Background: Conceptual review is a creative research method for generating new knowledge in the context of a vague and complex concept that helps to explain and clarify the concept, its components and its relation to related concepts. This study aimed to explain the methodology of conceptual review in the health system. Methods: Articles related to the conceptual research method were searched ...

This paper presents a Conceptual Graph (CG) framework to the Generation of Referring Expressions (GRE). Employing Conceptual Graphs as the underlying formalism allows a rigorous, semantically rich, approach to GRE. A number of advantages over existing work are discussed. The new framework is also used to revisit existing complexity results in a fully rigorous way, showing that the expressive po...

The goal of conceptual clustering is to build a set of embedded classes, which cluster objects based on their similarities. Knowledge organization aims at generating the set of most specific classes: the Generalization Space. It has applications in the field of data mining, knowledge indexation or knowledge acquisition. Efficient algorithms have been proposed for data described in <attribute, v...

We present the results of a weak lensing survey of six high-redshift (z > 0.5), X-ray selected clusters of galaxies. We have obtained ultra-deep R-band images of each cluster with the Keck Telescope, and have measured a weak lensing signal from each cluster. From the background galaxy ellipticities we create two-dimensional maps of the surface mass density of each cluster. We find that the subs...

This extended abstract describes a data structure (ACS) intended to serve as a target for conceptual schema languages and as a source for implementations. It indicates some of the uses to which it has been put.

In the present paper, we introduce an extension of the conceptual graph model suitable to the representation 7 of data which are modelized using fuzzy sets. We extend the specialization relation of the conceptual graph model to fuzzy conceptual graphs. Lastly we introduce a new way of comparing conceptual graphs, using the 9 idea that a graph may be compatible with another graph with a given de...

The generative capacity of language entails an ability to flexibly combine concepts with each other. Conceptual combination can occur either by using an attribute of one concept to describe another (attributive combination) or by forming some relation between two concepts to create a new one (relational combination). Prior research has addressed whether common or distinct processes support thes...

A question of central importance for researchers and practitioners is whether Information Technology (IT) can help build a competitive advantage in constantly changing environments. One characteristic of a firm’s IT infrastructure in particular, flexibility, has been posited as being a critical enabler in attaining competitive performance gains. Yet, despite this suggestion, there is scarce emp...
