Securing electronic documents is an important task. It secures the identity of a document. In this sense, methods (mainly cryptographic methods) have been put in place to guarantee secrecy meaning messages as well signing from certificates. The digital document only defined by its textual content. With rise OCRs, alteration and fraudulent use has increased. work we propose algorithm based on co...

The paper presents a novel approach to semantic search and navigation in office-like document collections. The approach is based on a semantic document model that we have developed to enable unique identification, semantic annotation, and semantic linking of document units of officelike documents. In order to semantically annotate document units and to link semantically related document units, ...

While price and data quality should define the major tradeoff for consumers in data markets, prices are usually prescribed by vendors and data quality is not negotiable. In this paper we study a model where data quality can be traded for a discount. We focus on the case of XML documents and consider completeness as the quality dimension. In our setting, the data provider offers an XML document,...

There are two main categories of multi-document summarization: term-based and ontology-based methods. A term-based method cannot deal with the problems of polysemy and synonymy. An ontology-based approach addresses such problems by taking into account of the semantic information of document content, but the construction of ontology requires lots of manpower. To overcome these open problems, thi...
