    Publication of XML documents without Information Leakage with data inference

    Recent applications are using an increasing need that publishing XML documents should meet precise security requirements. In this paper, we are considering data publishing applications where the publisher specifies what information is more sensitive and should be protected from outside world user. We show that if a given document is published carelessly then users can use common knowledge to guess any information. The goal here is to protect such information in the presence of data inference with common knowledge. The most important feature of XML formatting is it allows for adding schema declarations with integrity constraints to instance data and allow composing individual pieces of data in a tree-like fashion in which a link from a parent node to a sub tree carries some ontological information about the relationship between individual pieces of data This system work as inference problem in XML documents consists of potentially secrets and important information. Our work gives solution for this problem by providing the control mechanism for enforcing inference usability of XML document. Output of our work is again a XML document that is under their inference capabilities which neither contain nor imply any confidential information and it is indistinguishable from the actual XML document. In the proposed work it produced the weaken document which takes the consideration of inference capabilities and according to this modifies there schemas and produce inference proof documents.

    Evaluating Knowledge Representation and Reasoning Capabilites of Ontology Specification Languages

    The interchange of ontologies across the World Wide Web (WWW) and the cooperation among heterogeneous agents placed on it is the main reason for the development of a new set of ontology specification languages, based on new web standards such as XML or RDF. These languages (SHOE, XOL, RDF, OIL, etc) aim to represent the knowledge contained in an ontology in a simple and human-readable way, as well as allow for the interchange of ontologies across the web. In this paper, we establish a common framework to compare the expressiveness of "traditional" ontology languages (Ontolingua, OKBC, OCML, FLogic, LOOM) and "web-based" ontology languages. As a result of this study, we conclude that different needs in KR and reasoning may exist in the building of an ontology-based application, and these needs must be evaluated in order to choose the most suitable ontology language(s)

    An Entailment Relation for Reasoning on the Web

    Get PDF
    Reasoning on the Web is receiving an increasing attention because of emerging fields such as Web adaption and Semantic Web. Indeed, the advanced functionalities striven for in these fields call for reasoning capabilities. Reasoning on the Web, however, is usually done using existing techniques rarely fitting the Web. As a consequence, additional data processing like data conversion from Web formats (e.g. XML or HTML) into some other formats (e.g. classical logic terms and formulas) is often needed and aspects of the Web (e.g. its inherent inconsistency) are neglected. This article first gives requirements for an entailment tuned to reasoning on the Web. Then, it describes how classical logic’s entailment can be modified so as to enforce these requirements. Finally, it discusses how the proposed entailment can be used in applying logic programming to reasoning on the Web

    Identification of Design Principles

    This report identifies those design principles for a (possibly new) query and transformation language for the Web supporting inference that are considered essential. Based upon these design principles an initial strawman is selected. Scenarios for querying the Semantic Web illustrate the design principles and their reflection in the initial strawman, i.e., a first draft of the query language to be designed and implemented by the REWERSE working group I4
