Many initiatives to improve Business processes are emerging. The essential roles and contributions of Business Analyst (BA) and Business Process Management (BPM) professionals to such initiatives have been recognized in literature and practice. The roles and responsibilities of a BA or BPM practitioner typically require different skill-sets; however these differences are often vague. This vague...

This paper presents a new rule-based method to identify Spanish zero pronouns. The paper describes the comparative evaluation of a baseline method for the identification of zero pronouns with an approach that supplements the baseline by adding a set of restrictions treating impersonal sentences and other zero subject expressions. The identification rules have been tested on a new corpus in whic...

One of the specific aspects of our time is the existence of World Trade Organization as an important international center. This organization regulates the commercial laws among the countries, and tries to provide a suitable environment for trade by eliminating the subsidies using protection policies and making a better condition for competition. In order to achieve this objective, the economic ...

We analyze the strength of ties through three different clustering algorithms applied to co-authorship social networks from three different research areas. This study reveals if tie strength metrics can be used to evaluate clusters quality. We obtain different results for each algorithm and observe that Markov cluster algorithm provides the best results for co-authorship social networks. Also, ...

There has been a huge influx of business process modeling languages as business process management (BPM) and process-aware information systems continue to expand into various business domains. The origins of process modeling languages are quite diverse, although two dominant approaches can be observed; one based on graphical models, and the other based on rule specifications. However, at this t...

Many wireless sensor network (WSN) applications rely on precise location or distance information. Despite the potentials of WSNs, efficient location prediction is one of the subsisting challenges. This paper presents novel prediction algorithms based on a Kriging interpolation technique. Given that each sensor is aware of its location only, the aims of this work are to accurately predict the te...

Business process modeling is the foundation of business process management (BPM). Recently, there are a large number of business process modeling approaches in BPM domain. Still, there are many differences in specific applications, due to the diversity of characteristics of the process environment and the features of business process modeling approaches. In this paper, we attempt to find the ad...

In this paper a comparative analysis of feature selection using typical testors applied on astronomical data, is presented. The comparison is based on the classification efficiency using typical testors as feature selection method against the classification efficiency using Ramirez (2001) method, which uses genetic algorithms. The well-known K-nearest neighbors rule (KNN) was used as classifier...

A survey was conducted of 157 Canadian Information Systems (IS) personnel in organizations throughout Canada using a modi®ed Delphi technique and follow-up interviews to identify the perceived critical issues in IS during the following 5 years. The important issues included: (1) building a responsive IT infrastructure; (2) improving IS project management practices and (3) planning and managing ...

The application of computer simulation as a research method raises two important questions: (1) Does simulation really offer added value over established methods? (2) How can the danger of arbitrariness caused by the extended modelling possibilities be minimised? We present the concept of stylised facts as a methodological basis for approaching these questions systematically. In particular, sty...
