“…In our empirical analysis, we applied OLSR [24][23] and Web-COBRA [29], since they have been applied in previous studies to assess the effectiveness of Web Objects in estimating Web application development effort [29] [30]. Furthermore, we also employed CBR [1] since, together with OLSR, it is one of the most diffuse techniques in the industrial context and in several researches to estimate Web application development effort (see e.g., [10]…”

“…The COSMIC [9] method has been applied to Web applications by some researchers in the last years [10] [19]. In particular, Mendes et al applied it to 37 Web systems developed by academic students, by constructing an effort estimation model with OLSR [19].…”

“…Unfortunately, this model did not provide good estimations and replications of the empirical study were highly recommended. Subsequently, an empirical study based on the use of 44 Web applications developed by academic students, was performed to assess the COSMIC approach [10]. The effort estimation model obtained by employing the OLSR provided encouraging results.…”

“…Indeed, size measurement methods, conceived and widely accepted for traditional software systems, such as the Function Point Analysis (FPA) [14], can fail to capture some specific features of Web applications [25]. Some measures have been defined so far (see e.g., [10][11] [26]), and among them, Web Objects were introduced by Reifer [26] by adding four new Webrelated components (namely Multimedia Files, Web Building Blocks, Scripts, and Links) to the five function types of the FPA method. In his original formulation [26][27], Reifer reported improved prediction performances of Web Objects over Function Points, but no details were provided about the empirical analysis he performed.…”

Abstract. The spreading of Web applications has motivated the definition of size measures suitable for such kind of software systems. Among the proposals existing in the literature, Web Objects were conceived by Reifer specifically for Web applications as an extension of Function Points. In this paper we report on an empirical analysis we performed exploiting 25 Web applications developed by an Italian software company. The results confirm the ones obtained in a previous study and extend them in several aspects, showing the robustness of the measure with respect to the size and technologies of the applications, and to the employed estimation techniques.

“…The methods of estimating effort of conventional software are not convenient to grasp the features of software development which affect the Webapps size and effort. [4] There are two techniques for sizing Webapps: lines of code technique (LOC) and functional size technique (FS). LOC relies on the programming language and it can be applied when the project is finished.…”

Effort estimation is the important task in project planning phase in software industry. The process is complex as the complexity and size of software to be built. In the conventional software, there are many classical techniques have been used for effort estimation purpose. These techniques are not suitable to be applied on Webapp development because of the difficulty of sizing software in Webapp and the huge amount of data. In this work we proposed an algorithm for estimating the effort of Webapp software using COSMIC function point combined with the conceptual model of the software which is data based driven from Webapp. The method focuses on the extensive of data movement in the software which may be elicited from the conceptual model. For this purpose 19 Webapps with their conceptual models are used for effort estimation. Effort estimation model was built using cubic regression model and accuracy indicators such as MRE, MMRE, MdMRE, and Pred(0.25) were used to evaluate the efficiency of the proposed method.
