There are various models like Capability Maturity Model (CMM), ISO, etc. available to measure process improvement. However management role is vital for effective process improvement implementation strategy. This paper briefly presents an assessment of all the factors which, if taken care by the management effectively, can ensure success in information system process improvement and proposes a general 2-stage framework for process improvement. The framework presents stochastic simulation model which is tailored to the dynamics of software projects, and which takes management plan and individual processes as input to show how simulation can be used to achieve effective project management.Article Citation - WoS: 35Citation - Scopus: 42The Role of Absorptive Capacity, Communication and Trust in Erp Adoption(Elsevier Science inc, 2016) Mayeh, Maral; Ramayah, T.; Mishra, Alok; Software EngineeringThe use of Enterprise Resource Planning (ERP) systems is proven to be valuable in several ways and it is considered a necessity in today's business. However, despite the high cost and efforts required in implementing ERPs, the success rate is reported unsatisfactory in Iranian organizations. It is argued that the success of ERP implementation is significantly related to the users' adoption behavior. As one of the most important predictors of adoption behavior, this study investigates factors affecting the intention to use ERP systems. In particular, using Technology Acceptance Model (TAM), we examined the effects of absorptive capacity, communication and trust on the intention to use ERP systems. A questionnaire was sent to ERP users in 7 organizations in Iran, and 184 responses were used for the analysis. The findings suggest that trust, together with perceived ease of use and perceived usefulness, have a positive significant relationship with intention to use ERR Furthermore, absorptive capacity and communication have a direct effect on the perceived ease of use which, in turn, impacts the intention to use ERP. As such, this study advances the current knowledge of adoption behavior by investigating the role of trust, communication and absorptive capacity on the intention to use. (C) 2016 Elsevier Inc.

In this recpect, agent methodologies aim to covering all important components needed to build software systems. The success of agent methodologies depends on the development of all the necessary processes within different software stages, such as analysis, design, implementation, testing and maintenance. This work introduces a comparative study of agent approches with the purpose to asseses and compare the development lifecycle processes of four different well-known AOSE methodologies, ADELFE, PASSI, Gaia and O-MaSE to define the similarities and differences between them. We can conclude that, the development of standard agent approach that supports Multi-Agent Systems (MAS) based has become an urgent need.Doctoral Thesis Kelime Gömme Kuralları ve Metin Sınıflandırması Tabanlı Makine Öğrenme Üzerine Bir Çalışma(2019) Al-gartanee, Asmaa; Mıshra, Alok; Görür, Abdül Kadir; Software EngineeringÇevrimiçi bilgilerin, internet üzerinden temin edilebilen elektronik belgelerin ve dijital kütüphanelerin sayısındaki ani artış ile beraber metin belgelerinin kategorize edilmesinde zorluklar oluşmaya başlamıştır. Metin sınıflandırması teknik sürecinin kara kutusunun gösterilebileceği en esnek yöntemlerden birisi olarak görülen kural tabanlı yaklaşımlar olarak gömme, kural tabanlı ve makine öğrenme yaklaşımı bu problemin bu nedenle en iyi çözümleridir. Sınıflandırma sürecinin detayları görülebilir ve iyi sonuçlar elde etmek için bazı araçlar ve yeni talimatlar eklenebilir. Bu yaklaşımın bilgi alma, e-devlet, bilgi süzme, metin veri tabanları, dijital kütüphaneler ve diğer uygulamalar için değeri yüksektir. Gömme tekniği ve kural tabanlı oluşturma problemi metin kategorizasyonunda çok belirgin bir öneme sahiptir. Gömme tekniğinin ana fikri, metin kategorizasyon motoruna bir belgeyi bir kategoriye dönüştürmesinde yardımcı olabilecek bilgilendirici ve bilgilendirici olmayan kelimeleri tutabilecek bir teknik kullanarak anahtar kelimelerin önemini tespit etmektir. Bu tez, kelimeden vektöre (word2vec) ve belgeden vektöre (doc2vec) yaklaşımları için gömme tekniği kullanan kural tabanlı yaklaşımı ele almaktadır. Benzerlik hesabına bağlı olarak anahtar kelimeler hazırlamada bu iki teknik kullanılacaktır. Bunun ardından, doğruluk, geri çağırma, hassasiyet ve F-Ölçümleri gibi performans değerlendirme ölçütlerini hesaplayarak sistemin en iyi performansını gerçekleştirecek bir sınıflandırıcı için kural tabanlı yaklaşımı uygulamada bu anahtar kelimeleri kullanırız. Reuters 21578 ve 20 haber grupları veri kümeleri üzerinde Reuters 21578 ve 20 haber grupları veri kümelerinin ilk on kategorisini tasnif etmek için deneyler yapılmıştır. Python dili; F-M Skoru, Hata oranı ve Doğruluk ile ölçülmekte olan yaklaşımın genel etkinliği ile izlenen kural tabanlı bir yaklaşımı meydana getirmek için kullanılmıştı. Reuters 21578 veri kümesi durumunda doc2vec (d2vRule) kullanan gömme tekniği ile kural tabanlı sonuçları; doğruluk % 79, geri çağırma % 75, F-Ölçümleri % 76.75, hata oranı % 9.28 ve doğruluk ölçümleri % 90.72 olarak bulunmuştur. 20 Haber Grubu veri seti için sonuçlar; hassasiyet % 76, geri çağırma % 66,64, F-Ölçümü % 70,98, hata oranı % 9,99 ve doğruluk ölçümü % 90,07 olarak bulunmuştur. Ayrıca, makine öğrenme algoritmaları J-RIPPER (JRip), One Rule (OneR) ve ZeroR, Reuter 21578 veri setine uygulandığında, JRip, OneR ve ZeroR için sırasıyla 0.713 - 0.752, 0.506 - 0.598 ve 0.219 - 0.39 F-Ölçümleri ve doğruluk ölçümleri elde ettik. . Buna ilaveten, bu algoritmaları veri kümemize uyguladığımızda, mutabakat sağlandı ve algoritmamızın (d2vRule) yukarıda belirtilen bu üç algoritmadan daha iyi performans gösterdiği ortaya çıktı. Bundan başka, değerlendirme ölçütlerine göre iyi bir sınıflandırma süreci sağlamaktadır. Diğer taraftan, gömme tekniğini word2vec modeliyle kullanırken, bu sonuçların hassasiyet, geri çağırma ve F-Ölçüm yaklaşımlarına bağlı olduğu tahmin edilebilir. Son olarak, kural tabanlı yaklaşımızın makine öğrenme sonuçlarından yani Naïve-Bayes, Naive Bayes Updateable, Rules.DecisionTable, Lazy. IBL ve Lazy.IBK. yaklaşımlarının sonuçlarından daha iyi olduğu açıktır. Kural-tabanlı (w2cRule) yaklaşımımız için geçerliliği denetlendiğinde, belirli bir referansın kural-tabanlı (RB) sınıflandırıcısının doğru sınıflandırılmış örneklerin % 82.19'u ile en yüksek doğruluğa sahip olduğu görülürken, Karar Ağacı (DT) Destek Vektör Makinesinin (SVM), Rastgele Orman (RF) ve Bayes Net (BN) sırasıyla % 81.72, % 81.49, % 81.19 ve % 77.85 doğruluk oranlarına sahiptirler ve Geçici Spesifiklik Skoru (TSS) sınıflandırıcısı referans alınan örneklerin % 77.19'unu doğru bir biçimde sınıflandırmıştır. Bununla beraber, kelimeden vektöre kural tabanlı sınıflandırıcımız (w2vRule) Reuter 21578 veri kümesi durumunda % 73 hassasiyet, % 77.61 geri çağırma, % 75.09 F-Ölçümü, % 10.09 hata oranı ve % 89.91 doğruluk ölçüm seviyeleri gözlemlenmiştir. Bundan dolayı, önceki kural tabanlı ve makine öğrenme sınıflandırıcıları ile kıyasladığımızda en iyi sonuçları vermiştir.Review Citation - Scopus: 0Web Privacy: a Commercial, Social and Technological Perspective(2003) Mishra,A.; Software EngineeringPeople all over the world are increasingly concerned about the privacy issues surrounding the personal information collected by the private organizations, governments and employers.
