GVC is a new information retrieval model that is based on Graph Vertices Comparison (GVC). It implements a new similarity measure to compare documents and users' queries based on graph matching. In this model, graphs are composed of two types of nodes. Documents, queries and indexing terms are viewed as vertices of this bipartite graph where each edge goes from a document or a query –first type...

Access to XML-based documents currently relies on query languages that are closely tied to the document structures, i.e. when looking for information one has to be aware of this structure and cannot easily specify the information needs conceptually. Our approach uses ontologies to access sets of distributed XML documents on a conceptual level. We integrate conceptual modeling, inheritance, and ...

Over the past quarter-century, many covariates of divorce have been identified. However, the extent to which the effects of these covariates remain constant across time is not known. In this article, I examine the stability of the effects of a wide range of divorce covariates using a pooled sample of data taken from five rounds of the National Survey of Family Growth. This sample includes consi...

Assessment of seasonal changes in surface water quality is an important aspect for evaluating temporal variations of river pollution due to natural or anthropogenic inputs of point and non-point sources. In this study, surface water quality data for 16 physical and chemical parameters collected from 22 monitoring stations in a river during the years from 1998 to 2001 were analyzed. The principa...

Potato waffles and baked beans for breakfast. A touch of salt and vinegar and I have a real treat on my hands., A slightly unusual breakfast, some might say, but then again, sometimes unusual is better than usual. Hmmmm ... Delicious! Four minutes later, no more waffles. It's as though they have disappeared. Born out of the freezer, they spent their short lives in my toaster. Both of them. I wo...

In text database systems, query terms are stemmed to allow them to be connated with variant forms of the same word. On the one hand, stemming allows the query mechanism to nd documents that would otherwise not contain matches to the query terms; on the other hand, automatic stemming is prone to error, and can lead to retrieval of inappropriate documents. In this paper we investigate several ste...

A number of research and software development groups have developed technology for identifying terms and names in documents and associating them with concepts and named entities, but few have addressed coreference of concepts and entities across multiple documents in a collection. Cross-document coreference is challenging, since a collection of documents consists of multiple discourse contexts,...

The W3C has recently released a language for Web-based Multimedia presentations called SMIL: the Synchronized Multimedia Integration Language. GRiNS is an authoring and presentation environment that can be used to create SMIL-compliant documents and to play SMIL documents created with GRiNS or by hand. This paper discusses GRiNS as a tool for creating multimedia education materials on the Web.
