Abstract-There is a wealth of sensitive information available on the Web about any individual that is generated either by her or by others on social networking sites. This information could be used to make important decisions about that individual. The problem is that although people know that searches for their personal information are possible, they have no way to either control the data that is put on the Web by others or indicate how they would like to restrict usage of their own data.We describe a framework called Policy Aware Social Miner (PASM) that would provide a solution to these problems by giving users a way to semantically annotate data on the Web using policies to guide how searches about them should be executed. PASM accepts search queries and applies the user's policies on the results. It filters results over data the user owns and provides the user's refutation link on search results that the user does not own. These usage control mechanisms for privacy allow users to break away from siloed data privacy management and have their privacy settings applied to all their data available on the Web.

“…Current systems mostly preferred RDF-based models, e.g. Open Annotation (OA) model 1 which is currently in beta version but it is already used by a number of systems and projects [13][14][15]. Metadata in RDF-based format should be stored in triple stores that are good for inference but, they are not effective for manipulation with whole objects.…”

Abstract. Semantics over the Web content is crucial for web information systems, e.g. for effective information exploration, navigation or search. However, current coverage of the Web by semantics is insufficient. Web information systems mostly create their own content based metadata (e.g., identified keywords) and user collaboration metadata (e.g., implicit user feedbacks) in a form of information tags -structured information with semantic relations to the tagged content. By information tags web information systems build a lightweight semantics over the Web content, in which they can store knowledge and information about the content and interconnections between information artifacts of the content. Crucial problem of information tags lies in dynamicity of the Web whose content is continually modified. This together with influence of time can lead to invalidation of information tags which are closely related to tagged content. We address this issue via maintenance approach based on automatically and semi-automatically generated rules that respect changes on the Web and time aspect. The maintenance utilizes a rule-based engine which watches changes in the tagged content, identifies dependencies among maintenance rules and builds optimal strategy of rules application. We evaluate proposed maintenance approach in two domains -programing repositories and digital libraries, which use shared information tags repository.

“…The question of how can we keep these annotations persistent over time has been discussed by Sanderson and Van de Sompel [7]. Their solution to keep the annotation persistent is Memento [9], an inter-archive approach for accessing archived representations of web resources that utilizes HTTP content negotiation in the dimension of "datetime".…”

Persistent annotations deserve new URIs

Some digital libraries support annotations, but sharing these annotations with other systems or across the web is difficult because of the need of special applications to read and decode these annotations. Due to the frequent change of web resources, the annotation's meaning can change if the underlying resources change. This project concentrates on minting a new URI for every annotation and creating a persistent and independent archived version of all resources. Users should be able to select a segment of an image or a video to be part of the annotation. The media fragment URIs described in the Open Annotation Collaboration data model can be used, but in practice they have limits, and they face the lack of support by the browsers. So in this project the segments of images, and videos can be used in the annotations without using media fragment URIs.
