Forging Trust and Privacy with User Modeling Frameworks: An Ontological Analysis
Keywords: trust and reputation; privacy; user modeling; ontologies; semantic adaptive social web
With the ever increasing importance of social net- working sites and services, socially intelligent agents who are responsible for gathering, managing and maintaining knowledge surrounding individual users are of increasing interest to both computing research communities as well as industries. For these agents to be able to fully capture and manage the knowledge about a user’s interaction with these social sites and services, a social user model needs to be introduced. A social user model is defined as a generic user model (model capable of capturing generic information related to a user), plus social dimensions of users (models capturing social aspects of user such as activities and social contexts). While existing models capture a proportion of such information, they fail to model and present ones of the most important dimensions of social connectivity: trust and privacy. To this end, in this paper, we introduce an ontological model of social user, composed by a generic user model component, which imports existing well-known user model structures, a social model, which contains social dimensions, and trust, reputation and privacy become the pivotal concepts gluing the whole ontological knowledge models together.

Un exemple de possibilité de liens ajoutés pour une recheche de films sur "Internet Movie Data Base" qui donne accés au catalogue en ligne d'une bibliothèque... A étudier Pendant la consultation d'un titre sur IMDB, il place un lien vers une recherche pour ledit titre dans la bibliothèque du comté de Lycoming System (Pennsylvanie). While viewing a title on IMDB, it will place a link to a search for said title in the Lycoming County Library System (Pennsylvania). ·
People have difficulties using computers. Some have more difficulties than others. There is a need for guidance in how to evaluate and improve the accessibility of systems for users. Since different users have considerably different accessibility needs, accessibility is a very complex issue.
ISO 9241-171 defines accessibility as the "usability of a product, service, environment or facility by people with the widest range of capabilities." While this definition can help manufacturers make their products more accessible to more people, it does not ensure that a given product is accessible to a particular individual.
A reference model is presented to act as a theoretical foundation. This Universal Access Reference Model (UARM) focuses on the accessibility of the interaction between users and systems, and provides a mechanism to share knowledge and abilities between users and systems. The UARM also suggests the role assistive technologies (ATs) can play in this interaction. The Common Accessibility Profile (CAP), which is based on the UARM, can be used to describe accessibility.
The CAP is a framework for identifying the accessibility issues of individual users with particular systems configurations. It profiles the capabilities of systems and users to communicate. The CAP can also profile environmental interference to this communication and the use of ATs to transform communication abilities. The CAP model can be extended as further general or domain specific requirements are standardized.
The CAP provides a model that can be used to structure various specifications in a manner that, in the future, will allow computational combination and comparison of profiles.
Recognizing its potential impact, the CAP is now being standardized by the User Interface subcommittee the International Organization for Standardization and the International Electrotechnical Commission. ·
The Java User Groups Community aims to be the meeting point for JUGs, in order to create a better interaction among the groups, expanding and strengthening the Java movement worldwide.
Here, in the JUGs Community page, JUG leaders and JUG members can come to share information about creating, joining and running a JUG, and to work together in tools, projects and discussions that are important for the worldwide Java community.
As a community of JUGs, projects submitted to this community must represent groups of users, that focus primarily in Java and Java-related technologies. Each JUG project can have their own technical sub-projects. ·
Based on a Flickr username (not user id), returns a feed of comments on photographs posted by user together with the any comments a user has posted to other photographs. Filter out the any comments posted on any photographs that are not posted by the user such that popular photographs of other people won't also show up on the same feed, which as it often does, ·
