Semantics–informed geological maps: Conceptual modeling and knowledge encoding

Climate model uncertainty versus conceptual geological uncertainty in hydrological modeling

Projections of climate change impact are associated with a cascade of uncertainties including in CO2 emission scenarios, climate models, downscaling and impact models. The relative importance of the individual uncertainty sources is expected to depend on several factors including the quantity that is projected. In the present study the impacts of climate model uncertainty and geological model u...

Conceptual Modeling for a Web of Knowledge

The current web is a web of linked pages. Frustrated users search for facts by guessing which keywords or keyword phrases might lead them to pages where they can find facts. Can we make it possible for users to search directly for facts? Equivalently, can we turn the web into a web of facts (instead of a web of pages containing facts)? Ultimately, can the web be a knowledgebase—a web of knowled...

Using Knowledge from Wordnet for Conceptual Modeling

Using Concept Maps to Assess Conceptual Knowledge of Function

In this study I examine the value of concept maps as instruments for assessment of conceptual understanding, using the maps to compare the knowledge of function that students enrolled in university calculus classes hold. Twenty-eight students, half from nontraditional sections and half from traditional sections, participated in the study. Eight professors with PhDs in mathematics also completed...

Text Encoding Initiative Semantic Modeling. A Conceptual Workflow Proposal

In this paper we present a proposal for the XML TEI semantic enhancement, through an ontological modelization based on a three level approach: an ontological generalization of the TEI schema; an intensional semantics of TEI elements; an extensional semantics of the markup content. A possible TEI semantic enhancement will be the result of these three levels dialogue and combination. We conclude ...
