ABSTRACT
Quality of software has become an important issue with the increasing integration of software in various aspects of human society. Today’s software are very complex and they are deployed in a wide variety of execution environments and application domains. Both academia and industries are focusing on the research in software applications as many of our complex systems are software controlled, which motivated the publication of the current Special Issue in software.This Special Issue presents selected papers from the twelfth conference of the series (ICCIT 2009) held during December 21-23, 2009 at the Independent University Bangladesh. The first one was held in Dhaka, Bangladesh, in 1998. Since then the conference has grown to one of the largest computer and IT related research conferences in the South Asian region, with participation of academics and researchers from many countries around the world. Starting in 2008 the proceedings of ICCIT are included in IEEExplore.In 2009, a total of 473 full papers were submitted to the conference of which 150 were accepted after reviews conducted by an international program committee comprising 84 members from 16 countries with assistance from 83 reviewers. This was tantamount to an acceptance rate of 31.7%. Form these 150 papers only 9 highly ranked papers were invited for this Special Issue. The authors were invited to enhance their papers significantly and submit the same for review. Of those only five papers survived the review process and have been selected for inclusion in this Special Issue. The authors of these papers represent academic and/or research institutions from Bangladesh, Japan, and Norway. These five papers cover three domains of computing namely, data exchange, data search, and software development and engineering.In the first paper of this Special Issue, S. Karim proposes a data-exchange algorithm that produces semantically correct maybe answers to simple relational algebra queries over target schemas of data exchange under the closed world assumption. Given that there may be infinitely many maybe answers, he uses compact representation to compute possible (i.e., maybe) answers incrementally. The algorithm is then implemented for a fragment of relational algebra.M. Asaduzzaman, M. Shahjahan, and K. Murase, in the second paper, present a data search method that extracts interesting rules from the heterogeneous search histories of shopping in the Internet. They produce a homogeneous data set from their heterogeneous search histories without changing their characteristics of data. These data are trained by unsupervised neural network to extract interesting rules by inspecting the attributes of the customers.The last three papers focuses on software development and engineering. In the first of these, S. Islam and M. Rokonuzzaman split work breakdown structures (WBS) process into smaller process units which take right set of inputs with the right set of standard and put right set of practices in place to produce the work products with required standards and quality. The authors uses business case analysis phase of software projects as an example to demonstrate process centric concept of WBS to deal with project management challenges. Next, M. Rokonuzzaman and K. Choudhury integrate economics of software reuse with market positioning for delivering customized software solutions and thus improve the relevant decision making ability of software engineers. Finally, S. Islam, and S. Houmb consider the risks such as geographical and cultural distance otherwise associated with offshore outsourcing. The authors present a risk management framework that assesses and manages risks during the early development phases when risks can be more easily tackled at a reasonable cost. They use a goal-risk casual relationship model that identify and link project goals, risks and treatments and report on a study project focusing on the efficiency of the model.Finally, the Guest Editors would like to express their sincere gratitude to the anonymous reviewers of the Special Issue from different countries who have given immensely to this process. They have responded to the Guest Editors in the shortest possible time and dedicated their valuable time to ensure that the Special Issue contains high-quality papers with significant novelty and contributions.
