Web Services Relationships Binding for Dynamic e-Business Integration
Web services are becoming a major research topic for computer scientists, engineers and business consulting professionals. In this preface, I would like to outline the challenges of the current Web services research topics from the modeling, in-teroperability, and mathematical foundations points of view. Then I will introduce some research opportunities and possible future directions for moving Web services forward via some illustrative ideas such as business semantic computing as well as killer application driven Web services research approaches. For the business semantic computing aspect I will present some example application domains such as federated Web services discovery, dynamic Web services composition and extended business collaboration.

WS-EPM: Web services for enterprise project management
This work presents a new service-oriented architecture for enterprise project management that integrates business process, human resources and project management within an enterprise or across the value chain network. In the proposed WS-EPM framework, the project resources include business processes, skilled people, physical resources, control policies, and so forth. The project resources used in WS-EPM are described by WSResource properties language. In addition, the coordination of project resources is guided by a set of operations modeled by business process execution language for Web services (BPEL4WS). At the end of this paper, we present an industry application scenario that leverages the proposed WS-EPM for achieving maximum ROI with limited resources.

On-demand business collaboration enablement with web services
Businesses are increasingly outsourcing key operations and interacting with ever extending nets of partners. Running extended business-to-business (B2B) operations creates the need for more advanced human interaction while advancing the automation base of B2B functions. In this paper, we introduce a model for on-demand business process-based collaboration, namely, Extended Business Collaboration (eBC), and its major elements of modeling, and a configurable business protocol-enabling framework. We discuss some of the major research issues associated with facilitating extended business collaboration, and present our proposed Annotated Business HyperChain technology leveraging Web services and semantic annotation model. A research prototype is described, followed by some observations and discussion of open research issues requiring further exploration.

WS-trustworthy: a framework for Web services centered trustworthy computing
The emerging paradigm of Web services has been gaining significant momentum in the recent years since it offers a promising way to facilitate business-to-business (B2B) collaboration. However, it is not clear that this new model of Web services provides any measurable increase in computing trustworthiness. We propose a generic framework to control the trustworthiness of computing in the domain of Web services. A layered model is established to highlight four key elements: resources, policies, validation processes, and management. The robustness of this model exhibits its flexibility and extensibility. Examples utilizing our framework are reported.

A Method of Enabling Automated Invocation of Web Services
While Web services provide an essential building block for realizing dynamic e-business by facilitating standardsbased program-to-program interaction, they do not address many business aspects of communication such as security, access control, business partner selection, service level agreement monitoring, and logging. In this paper, we propose a service-oriented framework that provides these much needed infrastructure services. Using the framework, service providers can prepare their business applications for publishing as Web services, and specify access controls on their services in the registry while service requestors can find suitable service providers and invoke their services dynamically. The framework ensures that all transactions are secure, monitored for service level agreements and logged for audit purposes. By providing business utility services and automation technology founded on Web services, we believe that, our framework takes Web services to the next level in supporting dynamic e-business.

IGroup: a web image search engine with semantic clustering of search results
In this demo, we present IGroup, a Web image search engine that organizes the search results into semantic clusters. Different from all existing Web image search results clustering algorithms that only cluster the top few images using visual or textual features, IGroup first identifies several query-related semantic clusters based on a key phrases extraction algorithm originally proposed for clustering general Web search results. Then, all the resulting images are separated and assigned to corresponding clusters. To make the best use of the clustering results, a new user interface is proposed.

An Experimental Assessment of the 2D Visibility Complex
We make an experimental assessment of the size of the 2D visibility complex of disjoint unit discs randomly distributed in the plane with density $\mu$. We observe that the number of free bitangents is asymptotically linear in the number of discs and we study the dependence of the linear asymptote in terms of the density of the scene. Specifically, for a particular range of scene densities $\mu$, we exhibit an approximation of the number of free bitangents in terms of $\mu$ and the number $n$ of discs, for $n$ larger than some function of $\mu$. We also notice how our approximation gained for rather large densities can be used to guess the onset of the linear behavior for small densities.

Face Annotation for Family Photo Album Management
In this paper, we propose a framework to semi-automatically annotate faces in family photo albums. The core of the framework is the features used to define face similarity and this results in the learning algorithm used to refine automatic face annotation. We have adopted similarity based search and relevance feedback ideas developed for content-based image retrieval and a set of simple yet effective color and texture based features, in addition to the traditional face recognition features, in performing candidate annotation search. The experimental evaluation of the proposed approach has been conducted with a family album of 1707 photos and the results show that the proposed approach is an effective and efficient one for semi-automatic family photo album annotation.

Some properties of 3-domination-critical graphs
Abstract A graph G is 3- γ -critical if its domination number γ is 3 and the addition of any edge decreases γ by 1. Wojcicka conjectured that every 3- γ -critical graph with minimum degree δ ⩾2 has a hamiltonian cycle. In this paper, we prove that if G is a 3- γ -critical connected graph of order n with minimum degree δ ⩾2, then (1) G is 1-tough; (2) the circumference of G is at least n −1.

Similarity space projection for web image search and annotation
Web image search has been explored and developed in academic as well as commercial areas for over a decade. To measure the similarity between Web images and user queries, most of the existing Web image search systems try to convert an image to textual keywords by analyzing the textual information available (such as surrounding text and image filename) with or without leveraging image visual features (such as color, texture, shape). In this way, the existing systems transform "Web images" to the "query (text)" space so as to compare the relevance of images to the query. In this paper, we present a novel solution to Web image search - similarity space projection (SSP). This algorithm takes images and queries as two heterogeneous object peers, and projects them into a third Euclidean "similarity space" in which their similarity can be directly measured. The rule of projection guarantees that in the new space the relevant images are kept close to the corresponding query and those irrelevant ones are away from it. Experiments on real-world Web image collections showed that the proposed algorithm significantly outperformed traditional information retrieval models (such as vector space model) in the application of image search. Besides Web image search, we demonstrate that this algorithm can also be applied to image annotation scenario, and has promising performance. Thus, this algorithm unifies Web image search and image annotation into same framework.
