ABSTRACT
A primary challenge of the Web today is the lack of semantic interoperability among the massive number of resources that already exist and are continually being generated at rapid rates. The Semantic Web (SW) holds the promise to build a Web-scale topology of linked and interoperable resources, which will allow users to search simultaneously across many different and distributed information structures. This chapter focuses on defining the long-tail concept in the context of scientific resources, identifying the role of the SW in increasing the interoperability of long-tail resources, analyzing the reasons for their semantic heterogeneity, and introducing the design and architecture of a Geosemantic framework for addressing the semantic heterogeneity challenges associated with the interoperability of these long-tail resources. Large collections of distributed and heterogeneous Web resources are often referred to in scientific communities as long-tail resources. Semantic Annotation of a Web resource is defined as an association of one or more SNs with a Web resource.
