a bstract background:  one of the key strategies in students’ learning is the in fl uence of models on them. understanding the factors affecting the implementation of role-modeling process in education will help to make greater use of this training strategy. this study aimed to understand the experiences of role model instructors and nursing students about the facilitator factors in the role-mo...

Although Entity-Relationship (ER) modelling techniques are commonly used for information modelling, Object-Role Modelling (ORM) techniques are becoming increasingly popular, partly because they include detailed design procedures providing guidelines for the modeller. As with the ER approach, a number of different ORM techniques exist. In this paper, we propose an integration of two theoreticall...

In this paper, the author proposes a hierarchical security model (HSM) to enhance security assurance for multimedia big data. It provides role hierarchy management and security roles/rules administration by seamlessly integrating the role-based access control (RBAC) with the object-oriented concept, spatio-temporal constraints, and multimedia standard MPEG-7. As a result, it can deal with chall...

AbStrAct This chapter addresses the problem that traditional role-base access control (RBAC) models do not scale up well for modeling security policies spanning multiple organizations. After reviewing recently proposed Role and Organization Based Access Control (ROBAC) models, an administrative ROBAC model called AROBAC07 is presented and formalized in this chapter. Two examples are used to mot...

We present a sequential Semantic Role Labeling system that describes the tagging problem as a Maximum Entropy Markov Model. The system uses full syntactic information to select BIO-tokens from input data, and classifies them sequentially using state-of-the-art features, with the addition of Selectional Preference features. The system presented achieves competitive performance in the CoNLL-2005 ...

In this paper we describe a framework for the automatic transformation of databases from the conceptual to the internal level. Our approach ts in with the ANSI/SPARC three level architecture for database management systems. The framework consists of three components: structures (database schemata), populations (database contents) and operations (database manipulations). On the conceptual level ...

This paper presents WIA-Opinmine system developed by CUHK_Tsinghua Web Information Analysis (WIA) Virtual Research Center for NTCIR-8 MOAT Task. The system is deemed special due to three facts. Firstly, the system is able to handle Simplified Chinese and Traditional Chinese at the same time. A tool is developed to convert Traditional Chinese into Simplified Chinese before opinion analysis. Seco...
