Basic role based access control [RBAC] provides a mechanism for segregating access privileges based upon users' hierarchical roles within an organization. This model doesn't scale well when there is tight integration of multiple hierarchies. In a case where there is joint-tenancy and a requirement for different levels of disclosure based upon a user's hierarchy, or in our case, organization or ...

Role-based access control (RBAC) has recently received a lot of attention due to its exibility, expressive power and simplicity in administration. In RBAC permissions are associated with roles and users are made members of roles thereby acquiring the associated permissions. Centralized management of RBAC in large systems is a tedious and costly task. An appealing possibility is to use RBAC itse...

Developing features has been shown crucial to advancing the state-of-the-art in Semantic Role Labeling (SRL). To improve Chinese SRL, we propose a set of additional features, some of which are designed to better capture structural information. Our system achieves 93.49 Fmeasure, a significant improvement over the best reported performance 92.0. We are further concerned with the effect of parsin...

Constructing a lexical resource for Swedish, where compounding is highly productive, requires a well-structured policy of encoding. This paper presents the treatment and encoding of a certain class of compounds in Swedish FrameNet, and proposes a new approach for the automatic analysis of Swedish compounds, i.e. one that leverages existing FrameNet (Ruppenhofer et al., 2010) and Swedish FrameNe...

This paper provides an exhaustive account of the semantic features and the logical structure of causative active accomplishment verbs of movement. Following the approach of Componential Analysis, and described within the theoretical framework of Role and Reference Grammar, these verbs are arranged into three subgroups according to a number of semantic variables related to their argument structu...
