Coreference or Not: A Twin Model for Coreference Resolution
A twin-model is proposed for coreference resolution: a link component, modeling the coreferential relationship between an anaphor and a candidate antecedent, and a creation compon...

Hybrid Role Hierarchy for Generalized Temporal Role Based Access Control Model
Generalized Temporal Role Based Access Control (GTRBAC) model that captures an exhaustive set of temporal constraint needs for access control has recently been proposed. GTRBAC’...
