Requirements engineering is a crucial phase of software engineering, and requirements prioritization is an essential stage of requirements engineering particularly in agile software development. Requirements prioritization goals at eliciting which requirements of software need to be covered in a particular release. The key point is which requirement will be selected in the next iteration and which one will be delayed to other iterations for minimizing risk during development and meeting stakeholders’ needs. There are many existing techniques for requirement prioritization, but most of these techniques do not cover continuous growth, change of requirements, and requirements dependencies. The prioritization techniques need to be more continuous, scalable, implemented easily and integrated with software development life cycle. This paper introduces a supporting tool for a proposed framework to prioritize requirements in agile software development. This framework tries to find solutions for the challenges facing this prioritization process such as how to make this prioritization continuous and scalable and how to deal with rapidly requirement changes and its dependencies. The proposed framework is validated in a real case study using its supporting tool, and the results are promising.

The key point is which requirement will be selected in the next iteration and which one will be delayed to other iterations for minimizing risk during development and meeting stakeholders' needs.

So, most of these prioritization techniques need to be more continuous, scalable, implemented merely and integrated with software development life cycle and not work separately. This paper introduces a framework to prioritize requirements in agile software development. This framework tries to find solutions for the challenges facing this prioritization process such as how to make this prioritization continuous and scalable and how to deal with rapidly requirement changes and its dependencies.

High code coverage is measured by the process of software testing typically using automatic test case generation tools. This standard approach is usually used for unit testing to improve software reliability. Most automated test case generation tools focused just on code coverage without considering its cost and redundancy between generated test cases. To obtain optimized high code coverage and to ensure minimum cost and redundancy a Multi-Objectives Evolutionary Algorithm approach (MOEA) is set in motion. An efficient approach is proposed and applied to different algorithms from MOEA Frame from the separate library with three fitness functions for Coverage, Cost, and Redundancy. Four MEOA algorithms have been proven reliable to reach above the 90 percent code coverage: NSGAII, Random, SMSEMOA,v and ε-MOEA. These four algorithms are the key factors behind the MOEA approach.

Software development industry has witnessed the growth of the agile movement and approaches. Applying the agile approaches and practices in the distributed environment will lead to gain a lot of benefits such as reduced costs, higher efficiency and better customization, on the other hand it will face many challenges for example working in different time zones, requirements changes, personal selection and knowledge management. In order to gain these benefits, it should address the challenges that will face the agile approaches in a distributed environment. One of the main challenges is managing the requirements changes during the process of distributed agile software development. Only few researches published in the literature, addressed the problem of requirements changes during the development process in distributed agile development. Most of the published researches in this context are based on industrial experiences which increases the need for combining the industry with academia within this area. In this paper an approach to manage requirements changes in distributed agile development is introduced. This suggested approach works to fill the gap between the industry and research in distributed agile development by combining the industrial practice and academic technique. This approach is based on a proposed feature model called a features tree. The approach is associated with a supporting software tool that helps to manage the requirement changes in distributed agile development. The supporting tool is tested and evaluated in real environments by software development professionals using an exhaustive set of criteria, and the results are promising.

Actual problems that threaten organizations are the excessive unnecessary organizational processes. The Business Process Reengineering (BPR) methodology is developed to improve the return of investment rates within organization. BPR guides to rearranging processes and removing unnecessary ones and consolidating the remaining processes into linear open system. Unfortunately, usage of modern Information Technology doesn't solve such problems in the Middle East countries and especially Egypt and doesn't realize the expected results. The limitations and drawbacks of IT projects refer mainly to the dependency on plan-driven team software process methodology that could not achieve frequently requirement changes of customers and usually exceeds estimated budget of the project. This research adopted the eXtreme Programming methodology using virtual team software process work providers in order to avoid these drawbacks and applied the proposed hybrid methodology to three main departments within Suez Canal Authority in Egypt

Cloud computing is becoming increasingly popular. Information technology market leaders, e.g., Microsoft, Google, and Amazon, are extensively shifting toward cloud-based solutions. However, there is isolation in the cloud implementations provided by the cloud vendors. Limited interoperability can cause one user to adhere to a single cloud provider; thus, a required migration of an application or data from one cloud provider to another may necessitate a significant effort and/or full-cycle redevelopment to fit the new provider's standards and implementation. The ability to move from one cloud vendor to another would be a step toward advancing cloud computing interoperability and increasing customer trust. This study proposes a cloud broker solution to fill the interoperability gap between different software-as-a-service providers. The proposed cloud broker was implemented and tested on a real enterprise application dataset. The migration process was completed and it worked correctly, according to a specified mapping model.

Information that are represented as text are either facts or opinions, whenever we need to make a decision, we often seek out the opinions of others which is one of the most influencing factors for our decisions. Traditionally, individuals can get opinions from friends and family while organizations use surveys, focus groups, opinion polls and consultants. Nowadays, opinions expressed through user generated content are considered as one of the important types of information which is available on the web, therefore, many resources have been emerged for expressing opinions including social media and others. This situation has revealed the necessity for robust, flexible Information Extraction (IE) systems, these systems have the availability to transform the web pages into program-friendly structures such as a relational database to reveal these opinions. In this paper, we propose an approach to classify the opinions of a document or a set of documents considering an object. The approach has been implemented and applied on a dataset of opinions. The proposed system discover the opinions provided for an object in a document or set of documents. The system discovers different types of opinionated statements, including the opinionated, comparative, superlative, and non- opinionated. The system has been applied on a set of 4000 sentences, and the results has been evaluated using the standard metrics, they are True positive, True negative, False positive, False negative, Precision, Recall, and F-score. We also provided a comparison of the presented work with previous work that has been presented in the same field. Index Terms—Opinion mining, opinion discovery, sentimental analysis, natural language processing

In the last few decades SOA (Service Oriented Architecture) has become the new trend in the IT industry. Many organizations tend to migrate to SOA in order to cope with the rapidly changing business. Effort estimation of SOA projects has become a real challenge to project managers due to the limited literatures addressing this issue. The traditional effort estimation techniques do not fit SOA projects entirely, as SOA has unique characteristics were not addressed by the traditional cost estimation approaches. These unique SOA characteristics include: loose coupling, reusability, composability and discoverability. On the other hand, cost estimation approaches that were proposed to estimate SOA projects, are still immature and most of them are impractical. They cannot be used in real life projects, as they are more guidelines than actual practical cost estimation approaches. This paper proposes an effort estimation approach for SOA projects that has been applied to different variety of services. It considers SOA characteristics and the various cost factors for different types of services including available, migrated, new and composed services. This proposed approach provides effort estimation technique for each type of service. The proposed approach also gives effort distribution among project phases for easily resources allocation. This framework has been applied to real life projects in the IT industry as the SOA project is divided into its component services and each service is estimated solely based on its type. The services' efforts are then aggregated to calculate the project’s overall effort. The estimated effort relative error in the case studies ranges from 3.66 % and 19.14%. Key words: Software engineering, effort estimation, cost estimation, phased effort estimation, SOA projects,

Automated test generation for object-oriented software typically consists of producing sequences of calls aiming at high code coverage. Test coverage is sometimes used as a way to measure how thoroughly software is tested. Coverage is used by software developers and sometimes by vendors to indicate their confidence in the readiness of their software. This survey studies and compares 7 coverage-based testing tools focusing on, but not restricted to coverage measurement. We also survey additional features, including program prioritization for testing, assistance in debugging, automatic generation of test cases, and customization of test reports. Such features make tools more useful and practical, especially for large-scale, real-life commercial software applications. This paper discusses the technical challenges that are testing tools need to address when handling Java classes coming from real-world open source projects, and when producing JUnit test suites intended for real users.

Cost estimation for Service Oriented Architecture (SOA) has not been addressed properly in the existing literatures. Most cost estimation approaches published in the literatures are more guidelines than actual practical estimation techniques. On the other hand, traditional software cost estimation techniques don’t fit SOA characteristics properly. In this paper, a phased effort distribution in legacy systems migration to SOA is presented. In this paper, we have identified several cost factors related to SOA. These cost factors have been distributed among different SOA project phases. Then weight for each cost factor has been assigned. This approach has been applied to different service migration strategies to SOA. The results have been obtained and analyzed. This approach represents one possible way to estimate the overall cost of a SOA project early and accurately by estimating the cost of only one phase of the project.

Abstract— This research aims to understand the impact of changing of multiple separated IS’s by one integrated IS on the End-user satisfaction as a surrogate to IS success. The proposed research model uses a combined approach deals with the new IS implementation as an organizational change based on change management effectiveness, user readiness for change, user resistance to change and Individual-related change self efficacy from one side and as technological innovation based on information quality, system quality and service quality from the other side. Data collected from a longitudinal field survey before, during and after a new IS implementation are analyzed to test the proposed hypotheses. The results indicate that End-user overall satisfaction is strongly influenced by change management, user readiness for change and IS quality factors during and post the implementation. The study draws attention to the role change management has in building user readiness, reduce change resistance, increase change self efficacy to increase End-user overall satisfaction of the new IS. Also, the important roles of quality factors of the new IS which depend on the significant contribution of information quality, system quality and service quality on the End-user overall satisfaction of the new information system especially, system quality during implementation and service quality after the implementation. The study contributes to the IS literature by providing a new perspective that complements the extant IS adoption as well as change management and IS quality research.

The automatic extraction of information from unstructured sources has opened up new ways for querying, organizing, and analyzing data by building a clean semantics of structured databases from a huge number of unstructured data and the society became more data oriented with easy online access to both structured and unstructured data. New applications of structured extraction came around such as the paper topic opinion mining, which is a type of natural language processing for tracking the mood of the public about a particular topic. Opinion mining, which is also called sentiment analysis, involves building a system to collect and examine opinions about the product or topic made in blog posts, comments, reviews or tweets. Automated opinion mining often uses machine learning, which is a component of artificial intelligence (AI).

Abstract - No doubt that software testing is an important activity in software development as no one can be sure that a software or program was successfully developed according to the needs requested without the software being tested. Validation rules for a system are only maintained thought embedded code in the system & only accessible via software developers. System data validations are a matter of change frequently due to business rules being changed or updated all the time. The only way to amend a code is either thought developers or in some cases an abroad vendor which causes business problems and delays especially in operational systems. This paper discusses how to solve this problem by separating the validation rules form the embedded code thought a declarative representation; this way will allow an agile updates of the system without any developer intervention which saves time and money.

Abstract Business Process Reengineering (BPR) is developed as „the fundamental rethinking process and radical change of three isolated business process management information system (BPMIS) as financial, industrial, and marketing and research departments in an Eastern non-IT Development firm in order to reduce cost and improve quality, service and speed‟. The Rational Unified Integrated Process (RUIP) is developed to break down BPR barriers and efforts. RUIP has two phases: 1) the reverse reengineering where legacy waterfall system is rationally unified and refactored and 2) the forward reengineering where processes are unified and integrated. Then, the RUIP is a large application. RUIP may fail to meet expectations, over time and over budget. The Software Development Methodology scored high ratings in BPR and RUIP critical success factors. Thus, the paper compares the most matured and CMMI acceptable software process methodologies: the team software process (TSP) and the eXtreme Programing software (XP). The paper proposes VTSP methodology to deploy the ability of the plan driven TSP to accelerate quality of software development and to deploy the simplicity of eXtreme programming (XP) and its ability to break down large projects into small iterations and to involve onsite customers and end users. The VTSP proposed a new adaptation to simplify and to automate TSP project monitoring and documentation Key words: VTSP methodology, BPR life cycle, RUIP application, Legacy system, Software Engineering, TSP methodology, XP methodology

Abstract - The industrial Process became more complicated, to the extent that it is not easy for the individual not only to understand quickly what is required from him, but also to deal with heavy industries such as steel, aluminum industry, mineral exploration and the work in the nuclear power stations. The same weakness in Cement Industry, which is the topic of this paper. Therefore finding the solution is the only way that enables the individual to reach fast understanding and to make experiments on an environment similar to the reality not only to prove concepts but avoid risks as well. Here the Virtual Reality (VR) found its way to penetrate these fields in spite of the difficulties that VR confronted.

ABSTRACT - In this paper, we present an automatic Face Recognition and Authentication (FRAS) System. The proposed System consists of three main phases, namely, Pre-processing, Feature Extraction, and Classification and Authentication phases. We use ORL faces database in the experiments. The most significant contribution of this work is using three face recognition methods; the Eigenface , the Fisherface and color histogram. The Eigenface is the first method considered as a successful technique of face recognition. The Eigenface method uses (PCA) to linearly project the image space to a low dimensional feature space. The Fisherface method is an enhancement of the Eigenface method that it uses (LDA) for the dimensionality reduction. The LDA maximizes the ratio of between-class scatter to that of within-class scatter; therefore, it works better than PCA for the purpose of discrimination. The color histogram based methods have proved simplicity and usefulness. Its idea was based on Color Histogram Quantization with 256 gray levels and using 24 quantization levels. We also use two classification methods (KNN) and (SVM). The proposed system has attained accuracy of 100% using color histogram features with KNN classifier and 95% using color histogram feature with SVM for ORL faces database of 40 persons with 10 image faces for each person.

The increased number of web services and the continuous need to integrate them into complex business processes have increased the need to enhance the web service discovery and selection processes. Service discovery based on semantics of web services is one of the main needs in service integration and composition . The main current approaches for semantic discovery of services are the keyword-based approach and the ontology-based approach . The plain simple keyword matching strategy is time-consuming and has inefficient recall and precision .The ontology-based strategy, on the other hand, is efficient, but may not be practical for the wide public use due to the lack of domain experts. In this paper, we propose a new approach that support semantic service discovery and service backing up in case of service unavailability .This approach is built using the FCA ( Formal concept analysis ) lattices and the WordNet .

Abstract— As good software requirements engineering process leads to good software analysis, design and coding, software requirements became a very important aspect for many software engineering researchers. Software requirements validation process plays the role of early testing for any software product. This paper proposes a new approach that merges between two existing ap-proaches of software requirements validation. These two approaches are based on the natural language but they differ in the modeling of this natural language. The first approach builds conceptual models and these models are easy to be understood by both the analyst and the user. The second approach builds an assessing tool that tries to find the ambiguity problems in the requirements document and the two approaches try to make the requirements validation process easier. This paper reaches a proposed model that combines the two approaches and can improve the software requirements validation process and the paper presents the initial results for the proposed model.

ABSTRACT - In the current marketplace, there are maturity models, standards, methodologies, and guidelines that can help organizations to improve the ways of doing business. However, most available improvement approaches focuses on a specific part of the business and do not take a systemic approach to the problems that most organizations are facing. The Capability Maturity Model Integration [CMMI] focuses on improving software and systems. CMMI consists of best practices that address product development and process improvement. It addresses practices that cover the product’s life cycle from conception to delivery and maintenance. There is an emphasis on both systems engineering and software engineering and the integration necessary to build and maintain the total product (Chrissis, Konrad, & Shrum, 2005) (Hefner, 2000). In this paper, we propose a software tool (prototype) to enhance the way projects control its quality processes using CMMI principles. The tool is evaluated by specialized organization in the UK (Blue Eye Consulting) the BEC used the tool in CSR project. The tool automates the activities of the process and product quality assurance process area under CMMI . It helps to evaluate the performed processes, work product against standards and procedures. It is based on identifying and documenting noncompliance issues. It helps to ensure that noncompliance issues are addressed. The tool ability to register noncompliance issues formally through a database and allocating dates and owners helps in integrating the project issues and improving across team communications.
