Role Based Reengineering of Web Applications
Found in: Web Site Evolution, IEEE International Workshop on
By Andrea De Lucia, Massimiliano Giordano, Giuseppe Polese, Giuseppe Scanniello, Genoveffa Tortora
Issue Date:September 2005
pp. 103-110
<p>We present an approach based on roles and access policies to improve security management of Web Applications. The approach first identifies the roles users have in the application, and then the software resources they can access based on the assig...
Visual Modelling of Role-Based Security Policies in Distributed Multimedia Applications
Found in: Multimedia Software Engineering, International Symposium on
By Massimiliano Giordano, Giuseppe Polese, Giuseppe Scanniello, Genoveffa Tortora
Issue Date:December 2004
pp. 138-141
The management of distributed multimedia systems is simplified when it is based on policies. The latter should be platform independent and expressed in terms of roles. Usually, they are defined through languages that conceptualize the hardware characterist...
Monitoring Online Tests through Data Visualization
Found in: IEEE Transactions on Knowledge and Data Engineering
By Gennaro Costagliola, Vittorio Fuccella, Massimiliano Giordano, Giuseppe Polese
Issue Date:June 2009
pp. 773-784
We present an approach and a system to let tutors monitor several important aspects related to online tests, such as learner behavior and test quality. The approach includes the logging of important data related to learner interaction with the system durin...
A Normalization Framework for Multimedia Databases
Found in: IEEE Transactions on Knowledge and Data Engineering
By Shi-Kuo Chang, Vincenzo Deufemia, Giuseppe Polese, Mario Vacca
Issue Date:December 2007
pp. 1666-1679
We present a normalization framework for designing of multimedia database schemes with reduced manipulation anomalies. To this end we introduce new extended dependencies involving different types of multimedia data. Such dependencies are based on distance ...
A Parsing Technique for Sketch Recognition Systems
Found in: Visual Languages and Human-Centric Computing, IEEE Symposium on
By Gennaro Costagliola, Vincenzo Deufemia, Giuseppe Polese, Michele Risi
Issue Date:September 2004
pp. 19-26
Several disciplines require the support of computer-based tools for creating sketches during early design phases. Unfortunately, most computer programs cannot parse and semantically interpret handwritten sketches.<div></div> In this paper we pr...
Visual Authorization Modeling in E-commerce Applications
Found in: IEEE Multimedia
By Shi Kuo Chang, Giuseppe Polese, Maurizio Cibelli, Roshan Thomas
Issue Date:January 2003
pp. 44-54
<p>The authors present a system for the visual specification of security policies. The system relies on the task-based authorization framework, which has been enhanced by visual languages to provide an intuitive way for specifying complex security co...
Extended Positional Grammars
Found in: Visual Languages, IEEE Symposium on
By Gennaro Costagliola, Giuseppe Polese
Issue Date:September 2000
pp. 103
Positional grammars are formalism for the definition and implementation of visual languages. They have already been used in the past as part of the VLCC system (Visual Language Compiler-Compiler) for the definition and the implementation of visual environm...
A Virtual Reality Environment for Web Browsing
Found in: Image Analysis and Processing, International Conference on
By Maurizio Cibelli, Gennaro Costagliola, Giuseppe Polese, Genoveffa Tortora
Issue Date:September 1999
pp. 1009
We present an environment for navigating the web through a virtual reality space. The two-dimensional internet space is mapped into virtual worlds according to predefined and/or inferred metaphors. Web and metaphor elements are given a conceptual represent...
Browsing the Web through Virtual Reality
Found in: Visual Languages, IEEE Symposium on
By Maurizio Cibelli, Gennaro Costagliola, Giuseppe Polese, Genoveffa Tortora
Issue Date:September 1999
pp. 194
We present a novel architecture to map the two-dimensional Internet space in virtual worlds according to predefined or inferred metaphors. Web elements and metaphor elements are both conceptualized as semantic-networks and are compared through an inference...
A Visual Language for Authorization Modeling
Found in: Visual Languages, IEEE Symposium on
By S.K Chang, Giuseppe Polese, Roshan Thomas, Souvik Das
Issue Date:April 1997
pp. 110
(2)Universit Via Allende (3)Odyssey Research Associates We present a visual language for the high level specification of authorization policies in automated environments. In order to accomplish the task, the visual language needs to provide an intuitive wa...
A framework for modeling and implementing visual notations with applications to software engineering
Found in: ACM Transactions on Software Engineering and Methodology (TOSEM)
By Gennaro Costagliola, Giuseppe Polese, Vincenzo Deufemia
Issue Date:October 2004
pp. 431-487
We present a framework for modeling visual notations and for generating the corresponding visual programming environments. The framework can be used for modeling the diagrammatic notations of software development methodologies, and to generate visual progr...
A data mining based system supporting tactical decisions
Found in: Proceedings of the 14th international conference on Software engineering and knowledge engineering (SEKE '02)
By Genoveffa Tortora, Giuseppe Polese, Massimiliano Troiano
Issue Date:July 2002
pp. 681-684
We present a decision support system based on data mining algorithms to be used for tactical decisions. The system has been developed and engineered to solve a typical problem involving strategic decisions: supporting a trainer of a basketball team in maki...
