A proposal is presented for integration between a graphical model, such as conceptual maps, and ontologies codified in the OWL language. Conceptual maps are a flexible form of knowledge representation, very useful in education-related collaborative environments; OWL is a language of knowledge representation oriented to semantic analysis and processing carried out by machines. Integration consis...

An experimental study of asynchronously communicating dyads tested the claim that conceptual representations could more effectively support collaborative knowledge construction in online learning than threaded discussions. Results showed that users of conceptual representations created more hypotheses earlier in the experimental sessions and elaborated on hypotheses more than users of threaded ...

A student conceptual model can be defined as a set of interconnected concepts associated with an estimation value that indicates how well these concepts are used by the students. It can model just one student or a group of students, and can be represented as a concept map, conceptual diagram or one of several other knowledge representation formats. Some e-assessment systems that automatically e...

This paper describes our work on developing effective, efficient and user-friendly interaction between a human operator and a mobile robot on performing spatial navigation tasks. In order to solve the spatially related communication problems caused by the disparity between human mental representation about spatial environments and that of a mobile robot, a qualitative spatial knowledge based fo...

This contribution details how conceptual characterizations of route knowledge can provide the basis for graphical route information in a cognitively adequate way. The approach is based on the theory of wayfinding choremes that originated from the leitmotif to reflect mental conceptualization processes—as a canonical representation—in different modes of externalization, primarily graphical and v...

BACKGROUND Realist reviews offer a rigorous method to analyze heterogeneous data emerging from multiple disciplines as a means to develop new concepts, understand the relationships between them, and identify the evidentiary base underpinning them. However, emerging synthesis methods such as the Realist Review are not well operationalized and may be difficult for the novice researcher to grasp. ...

Local and global bifurcation structure of the forced Lorenz model in the r−F plane is investigated. The forced Lorenz model is a conceptual model for understanding the influence of the slowly varying boundary forcing like Sea Surface Temperature (SST) on the Indian summer monsoon rainfall variability. Shift in the probability density function between the two branches of the Lorenz attractor as ...

The paper explains the conceptual framework of so called costs, effects and resources map that is intended to support performance analyses of the production value stream. Its purpose is to enhance manufacturing decision taking processes by providing relevant information related to production flows. The tool consists of five modules: production system model (value stream map), cost module, finan...

Event-related brain potentials (ERPs) were recorded from 18 normal adults as they read sentences that ended with words used literally, metaphorically, or in an intermediate literal mapping condition. In the latter condition, the literal sense of the word was used in a way that prompted readers to map conceptual structure from a different domain. ERPs measured from 300 to 500 msec after the onse...

The difficulties experienced by autistic individuals with regard to communication and language are widely known and well documented. Individuals with High functioning autism (ASD) are distinguished by relative preservation of linguistic and cognitive skills. However, problems with pragmatic language skills have been consistently reported across the autistic spectrum, even when structural langua...
