An object-oriented approach on Web information representation and derivation
A framework on Web information representation, extraction and derivation utilising the object-oriented approach is proposed. We define a structure which is similar to a class in object-oriented design and programming, and name it as an extended class (eclass). An eclass contains data attributes, member functions/methods, inference rules and presentations, and therefore, facilities information derivation and Web presentation. As an object-oriented approach, the framework also supports encapsulation, polymorphism, composition and inheritance. It can be implemented as an extension of an existing object-oriented programming language. An eclass can be extremely effective in content-dependent entity description. It describes a value under its context, consequently, the search engine not only searches the value, but also understands the meaning of the value in the context. We argue that information in any form or complexity can always be represented by instances of eclasses.

On splitting public keys for the public key infrastructure
Certificates and the public key infrastructure (PKI) play an vital role in electronic commerce. The framework of splitting the public key in the PKI is presented in this paper. Aimed to enhance the security level from both the perspectives of certificate issuing and certificate revocation, the framework splits the public key into multiple parts, and generates a certificate for each part. The framework is designed to be flexible to allow various levels of security depending on the requirements, while minimising changes to the existing e-commerce system and PKI. The key-split system maintains CA independence and allows for either smaller certificates or the size of key to be increased.

Web Service for Communication Service Management

Web service enablement of communication services
In this paper, we introduce Web service application session services, WS-session, for Web service based application session management in communication. A two-way Web service framework is described. It supports the use of Web service in the situation of telecommunication where the communication endpoint can be both a client and a peer-to-peer server. We describe the interface design in two-way Web service interaction based on the concept of tightly coupled interface and loosely coupled interface solutions. The proposed approach provides full support of asynchronous outbound operations and event notifications in communication services. It is implemented in a research prototype system that provides both standard based (ECMA-348) services and Avaya service extensions. In addition, we investigated the integration of our proposed approach with BPEL4WS. It allows the user to create new services through a drag-n-drop based service creation environment (ECLIPSE/BPEL4WS). It leads to a paradigm of service creation through Web service composition. More sophisticated telecommunication services are created from composing the basic services.

Ehrhart polynomials of cyclic polytopes
The Ehrhart polynomial of an integral convex polytope counts the number of lattice points in dilates of the polytope. In (Coefficients and roots of Ehrhart polynomials, preprint), the authors conjectured that for any cyclic polytope with integral parameters, the Ehrhart polynomial of it is equal to its volume plus the Ehrhart polynomial of its lower envelope and proved the case when the dimension d=2. In our article, we prove the conjecture for any dimension.

Feature Matrix Models for Information Extraction
To extract useful information which really contribute to the target issue from huge amounts of data or text description is an important task towards a number of research fields (e.g., genomics study and text mining). In this paper, a general feature matrix model (FMM) is proposed aiming to provide partial answer to this task. Specifically, one instantiation of FMM is used for identifying feature genes based on microarray data, and the other for extracting information according to case description.
