In this corporate world, the technology of Web services has grown rapidly and its significance for the development of web based applications gradually rises over time. The success of Business to Business integration rely on finding novel partners and their services in a global business environment. However, the selection of the most suitable Web service from the list of services with the identi...

Purpose – Churn prediction is a very important task for successful customer relationship management. In general, churn prediction can be achieved by many data mining techniques. However, during data mining, dimensionality reduction (or feature selection) and data reduction are the two important data preprocessing steps. In particular, the aims of feature selection and data reduction are to filt...

The rapid growth of the Chinese software industry has attracted attention from all over the world. Meanwhile, software requirements selection has a crucial impact on the final value of a software product and the satisfaction of stakeholders. This paper presents an empirical study, which focuses on the decision-making criteria for requirements selection in market-driven software development proj...

This paper discusses and optimizes an HMM/GMM based User-Customized Password Speaker Verification (UCP-SV) system. Unlike text-dependent speaker verification, in UCP-SV systems, customers can choose their own passwords with no lexical constraints. The password has to be pronounced a few times during the enrollment step to create a customer dependent model. Although potentially more “user-friend...

The availability of abundant data posts a challenge to integrate static customer data and longitudinal behavioral data to improve performance in customer churn prediction. Usually, longitudinal behavioral data are transformed into static data before being included in a prediction model. In this study, a framework with ensemble techniques is presented for customer churn prediction directly using...

The increasing number of functionally similar services requires the existence of a non-functional properties selection process based on the Quality of Service (QoS). Thus, in this article, authors focus on the provision of a QoS model, an architecture and an implementation which enhance the selection process by the annotation of Service Level Agreement (SLA) templates with semantic QoS metrics....

The problem of product assortment and inventory planning under customer-driven demand substitution is analyzed and a mathematical model for this problem is provided in this paper. Realistic issues in a retail context such as supplier selection, shelf space constraints, and poor quality procurement are also taken into account. The performance of three modified models, one that neglects customers...

This short paper presents a new research agenda to address problems of COTS software selection in the forthcoming decade. It describes the increasing shift towards software engineering based on COTS software packages, the limitations of current COTS/component-based software engineering methods and research efforts, and proposes a new research agenda to address the problems which arise from a so...

The OCM (Objects, Components, Models) group of the computer science department at Ecole des Mines de Nantes is interested in Aspect-Oriented Programming (AOP). This report is a collection of three short articles presenting work in progress at our lab. We focus on two approaches: AOP from a monitoring perspective (articles 1 and 2) and different approaches to achieve AOP weaving (article 3). Whe...

An Internet-based Virtual Private Network (IP-VPN) uses the open, distributed infrastructure of the Internet to transmit data between corporate sites. The configuration (network design) for a specific customer network typically requires the selection of network access lines and backbone sections that are provisioned by different organizations in a supply chain. Moreover, when configuring such a...
