Mining Roles with Semantic Meanings

by Ian Molloy, Hong Chen, Tiancheng Li, Qihua Wang, Ninghui Li, Elisa Bertino
"... With the growing adoption of role-based access control (RBAC) in commercial security and identity management products, how to facilitate the process of migrating a non-RBAC system to an RBAC system has become a problem with significant business impact. Researchers have proposed to use data mining te ..."

techniques to discover roles to complement the costly top-down approaches for RBAC system construction. A key problem that has not been adequately addressed by existing role mining approaches is how to discover roles with semantic meanings. In this paper, we study the problem in two settings with different

Annotation of Hyperlinks with Semantic Meaning

by Bilal Gonen, Samir Tartir, Ravi Pavagada
"... Abstract — Web pages in the web represent certain concepts in the domain they fall in, and the connections between them represent the relations between the concepts they represent. In the current web, people are using links blindly without knowing what these links point to, or what kind of relations ..."

of relationship this link represents. With the advent of the semantic web, concepts and relationships among them are represented in an ontology. This can be utilized to make links more meaningful. Web pages can be searched, browsed or even reorganized based on their concept and relationship labels. Links in a

I would like to thank Sandra Carberry, my advisor, for her limitless patience and impeccable advice. The hours she spent reviewing my drafts and listening to my half-formed theories over the past year were crucial to my arrival at a final paper of which I am genuinely proud. I would also like to thank Hui Fang, who provided invaluable input on both the theory and implementation of Wikimantic. Together, Sandra and Hui were vital for transforming a simple idea about query expansion into a full-fledged thesis on disambiguation with a strong theoretical backing and working implementation. I would like to thank my family for all the support they have given me and all the things they have taught me. Dad, who showed me how to think analytically and find wonder in the way the world works. Mom, who taught me how to work with words and communicate my thoughts to others. Kevin, whose positive attitude and competitive spirit has taught me the value of challenging myself and learning from failures. They have shaped me in so many ways that this thesis is as much a reflection of them as it is me, and their contribution runs even deeper than the considerable

Semantics of Context-Free Languages

by Donald E. Knuth - In Mathematical Systems Theory , 1968
"... "Meaning " may be assigned to a string in a context-free language by defining "at-tributes " of the symbols in a derivation tree for that string. The attributes can be de-fined by functions associated with each production in the grammar. This paper examines the implications of th ..."

Computing semantic relatedness using Wikipedia-based explicit semantic analysis

Scale-space and edge detection using anisotropic diffusion
