Web Page Annotation Using Web Usage Mining and Domain Knowledge Ontology

Today’s world the growth of the WWW has increased tremendously, the user is totally relying on web for information. Search engine provides the result pages to the user but all are not relevant so the challenging task is extracting the pages from web and provide to the user. WUM is an approach to extract knowledge and use it to the different purposes. In this paper new semantic approach is proposed based on WUM and Domain Knowledge Ontology. Ontology database preparation, it is also challenging task in this project

Semantic hierarchies for extracting, modeling, and connecting compliance requirements in information security control standards

Companies and government organizations are increasingly compelled, if not required by law, to ensure that their information systems will comply with various federal and industry regulatory standards, such as the NIST Special Publication on Security Controls for Federal Information Systems (NIST SP-800-53), or the Common Criteria (ISO 15408-2). Such organizations operate business or mission critical systems where a lack of or lapse in security protections translates to serious confidentiality, integrity, and availability risks that, if exploited, could result in information disclosure, loss of money, or, at worst, loss of life. To mitigate these risks and ensure that their information systems meet regulatory standards, organizations must be able to (a) contextualize regulatory documents in a way that extracts the relevant technical implications for their systems, (b) formally represent their systems and demonstrate that they meet the extracted requirements following an accreditation process, and (c) ensure that all third-party systems, which may exist outside of the information system enclave as web or cloud services also implement appropriate security measures consistent with organizational expectations. This paper introduces a step-wise process, based on semantic hierarchies, that systematically extracts relevant security requirements from control standards to build a certification baseline for organizations to use in conjunction with formal methods and service agreements for accreditation. The approach is demonstrated following a case study of all audit-related controls in the SP-800-53, ISO 15408-2, and related documents. Accuracy, applicability, consistency, and efficacy of the approach were evaluated using controlled qualitative and quantitative methods in two separate studies

1 Verification of Semantic Web Service Annotations Using Ontology-Based Partitioning

Abstract—Semantic annotation of web services has been proposed as a solution to the problem of discovering services to fit a particular need, and reusing them appropriately. While there exist tools that assist human users in the annotation task, e.g., Radiant and Meteor-S, no semantic annotation proposal considers the problem of verifying the accuracy of the resulting annotations. Early evidence from workflow compatibility checking suggests that the proportion of annotations that contain some form of inaccuracy is high, and yet no tools exist to help annotators to test the results of their work systematically before they are deployed for public use. In this paper, we adapt techniques from conventional software testing to the verification of semantic annotations for web service input and output parameters. We present an algorithm for the testing process, and discuss ways in which manual effort from the annotator during testing can be reduced. We also present two adequacy criteria for specifying test cases used as input for the testing process. These criteria are based on structural coverage of the domain ontology used for annotation. The results of an evaluation exercise, based on a collection of annotations for bioinformatics web services, show that defects can be successfully detected by the technique.
