For example, in the ACM Digital Library we added the prefix acmdlTitle: to search for a keyword only within the title of a study and the prefix recordAbstract: to search only in the abstract section. Similar data filtering phases were also performed in CrossRec to enable the recommendation of third-party libraries that might be added in the project under development. Thus, for the particular cases of the developed recommendation systems, either we re-implemented the tool, as it is the case with CrossSim, or we compared by performing experiments on the datasets that have been used in the original papers, as we did for CrossRec. In this sense, we see that CrossRec can produce good outcomes, not only in terms of success rate and accuracy but also sales diversity and novelty. Through the evaluation of CrossRec, we demonstrated that further than popularity, novelty and diversity are good indicators for assessing if the recommendation outcomes are meaningful. Email-Oh the good old email. ELL2 – In some certain contexts, the k-fold cross-validation technique is a good alternative to user studies: As previously mentioned, through CROSSMINER, we realized that user studies are cumbersome, and they can take a long time to conduct and complete.
In such cases, according to the facts shown in Table 2, the k-fold cross-evaluation has been a valuable technique that allowed us to evaluate most of the proposed recommendation systems even when the baselines were not available. Depending on the availability of data, we managed to avoid performing user studies by employing the k-fold cross validation technique WONG20152839 , which has been popularly chosen as the evaluation method for a model in Machine Learning. People are often not very keen on the experiments, since there is no incentive/reward for performing the required tasks. Not only does this creator specialize in photography, you may also check out his newest web site on the way to convert 3GP to AVI with 3GP to AVI converter which also helps people find the best 3GP to AVI converter on the market. In particular, while developing the CROSSMINER recommendation systems we always tried our best to identify the baselines to be used for the evaluations. So, to achieve more success it is essential to incorporate the latest and best technology. More importantly, we associate our work to various existing studies, aiming to highlight its main contributions.
Aiming at a reliable evaluation, for each query we mixed and shuffled the top-5555 results generated from the computation by each similarity metric in a single Google form and presented them to the evaluators who then inspected and given a score to every pair. In this way, we removed any bias or prejudice against a specific similarity metric. However, it seems that the metric has been neglected in evaluating recommendation systems in software engineering. Though these studies are highly related to our work, they provide a set of guidelines for developing and evaluating a generic recommendation system. The longest set (A) was made for people with 20/20 or farsighted vision, the mid-length set (B) was made for people with moderate nearsightedness and the shortest set (C) was made for people with more severe nearsightedness. It’s easy for people to imagine all of the ways criminals could abuse digital wallets. For instance, regarding third-party libraries recommendation Nguyen:2019:JSS:CrossRec ; 6671293 , objects are libraries that a system provides as its outcome. For example, a recommendation engine provides a developer with an artifact, e.g., a third-party library or an API function call, which does not belong to the ground-truth data at all; however, it is indeed useful for the current project.

The criticisms hit at the underlying power dynamic between Apple and its developer community: developers depend on Apple to reach users but Apple depends on developers to build apps that help attract users. Contract software developers may know a single programming language like PHP programming, Java programming, dot net programming etc, but they know the perfect procedure and thus produce error less creative programming for your website. As a result, we evaluated CrossSim by involving 15 developers of different background of knowledge. For example, to study CrossSim 8498236 ; Nguyen:2019:JSS:CrossSim , a user study with several developers’ involvement was the only option since there is no automated method to evaluate the similarity between two OSS projects. To perform such evaluation for CrossSim and compare it with the baselines, it has been crucial to design the experimental settings properly and clearly define the manual evaluation tasks by adhering to the taste-test methodology. ELL4 – Candidate baselines might not be reusable: When conceiving new recommendation systems there can be no baselines to compare with. We created these candidate values based on our intuition. Hybrid app development services and services are high-performing, robust, and feature-packed and created to be both secure and scalable, able to handle any business and Information Technology needs. COTS components and subsystems may now be purchased to support payload development. The components were ultimately squeezed inside a smaller logic board so the entire computer measures just 11.5 millimeters deep.
Concerning CrossSim, we decided to perform a user study, to mitigate any bias related to the fact that we re-implemented all the baselines. However, for the validity of our findings, we refer to the fact that all game participants were industrial software engineers, and participation in the survey was not mandatory. The authors emphasize that despite the important role that requirements engineering plays in software development, insufficient stakeholder participation in requirement elicitation and poor collaboration and communication still persist as very common problems. Also, when using a trained model for other projects, we introduced a preference mechanism on top of the model, which selects the most suitable role from a given set of roles present in a project (only valid in cross-project setting). Choosing suitable data plays an important role in the evaluations, and it depends on various factors, such as systems’ characteristics, baselines, evaluation purposes, or even constraints imposed by OSS platforms, e.g., GitHub and the Maven central repository. The goal was to enable the reuse of the collected data even for perspective evaluations to be done for future recommendation systems to be developed in the context of CROSSMINER. The primary limitations we experienced when evaluating the CROSSMINER recommendation systems were related to the GitHub APIs restrictions. And this is where our work comes in: we complement the existing studies by reporting on a specific use case, i.e., recommendation systems developed through the CROSSMINER project to satisfy requirements imposed by various industrial partners.
