The need for semantic interoperability between ontologies in a peer-to-peer (P2P) environment is imperative. This is because, by definition participants in P2P environment are equal, autonomous and distributed. For example, the synthesis of concepts developed independently by different academic researchers, different research labs, various emergency service departments and, hospitals and pharma...

Mapping relational data to RDF is an important task for the development of the Semantic Web. To this end, the W3C has recently released a Recommendation for the so-called direct mapping of relational data to RDF. In this work, we propose an enrichment of the direct mapping to make it more faithful by transferring also semantic information present in the relational schema from the relational wor...

Content-based indexing and retrieval of images and video requires a proper semantic description for image content. This paper discusses the mapping of high-level, application-specific, features to the visual primitives that are accessible through image processing techniques. A major difficulty is that there are currently no established methodologies for describing the contents of an image in te...

Semantic parsing is the task of mapping natural language sentences to complete formal meaning representations. The performance of semantic parsing can be potentially improved by using discriminative reranking, which explores arbitrary global features. In this paper, we investigate discriminative reranking upon a baseline semantic parser, SCISSOR, where the composition of meaning representations...

For a generic flexible efficient array antenna receiver platform a hierarchical reconfigurable tiled architecture has been proposed. The architecture provides a flexible reconfigurable solution, but partitioning, mapping, modelling and programming such systems remains an issue. A semantic model has been presented to allow the development of the model for the specification, design and implementa...

In this paper we present a 3D semantic outdoor mapping system with multi-label and resolution octree maps based on the OctoMap mapping framework. The semantic labeling of point clouds uses conditional random fields. Speeding up the conditional random field, we use an adaptive graph downsampling method based on voxel grids and the histogram-of-oriented-residuals operator to describe the local po...

In this paper we present a new approach for the automated mapping of formal descriptions into activity thread implementations. Our approach resolves semantic conflicts by reordering of statements at compile time. This simplifies the mapping process and considerably improves the efficiency of the generated code. The approach is implemented in the SDL compiler COCOS. We describe the approach as w...

In October of 2004, the University of Southampton and Hewlett Packard Laboratories at Bristol joined forces to work on a collaborated project, CROSI, in order to investigate semantic integration. The project lasted 12 months and its primary focus was the use of Artificial Intelligence technology, like ontologies, in the Semantic Web environment in order to research issues related to ontology ma...

Traditionally, semantic reconciliation was performed by a human observer (a designer or a DBA) [8] due to its complexity [3]. However, manual reconciliation (with or without computer-aided tools) tends to be slow and inefficient in dynamic environments and does not scale for obvious reasons. Therefore, the introduction of the semantic Web vision and the shift towards machine understandable Web ...
