The Extract Data is the first step of the thematic synthesis (Section 3.4). To answer RQ2, we analyze the data from fields F1 and F2 (see Table 4), which are claims regarding the effects of CI, i.e., any consideration in a study indicating a positive or negative effect of CI on the software development phenomena. The benefits resulting from the reuse of properly selected open-source projects are manifold including the fact that the system being implemented relies on open source code, “which is of higher quality than the custom-developed code’s first incarnation” SS04 . However, to the best of our knowledge, an experience report extracted from real development projects is still missing. Furthermore, it also recommends real code snippets that can be used as a reference to support developers in finalizing the method definition under development. Engineers tend to work with others in teams, while developers are often in a solitary environment. Must your organisation engage the same software developer to perform the work? Technology leaders must step up with their communications. Requirement prioritization: The list of requirements produced in the previous step can be very long, because users tend to add all the wanted and ideal functionalities even those that might be less crucial and important for them. Being able to group developers with similar behaviors, for instance, based on the time they spent on each activity or working on a specific artifact, is a step forward in that understanding.
Moreover, OSS platforms are also an essential source of consultation for developers in their daily development tasks 7887704 . There are also third party platforms not controlled by a mobile provider, such as the Amazon App Store. If this is the case, then your definition of ‘done’ is going to be different from a start-up that is aiming at working on successive versions of an app or software product. The Restlet framework includes a Servlet hook up that you need to configure before deploying your app. For this reason, the green and red boxes contain invocations of HTMLUnit,121212http://htmlunit.sourceforge.net/ a direct competitor of jsoup that includes different browser user agent implementations, and jsoupcrawler a custom extension of jsoup. Most OSS forges typically sustain vibrant user and expert communities which in turn provide decent support, both for answering user questions and repairing reported software bugs. To recover the questions and projects, a search string was defined considering the common terms used to characterize the COVID-19 pandemic: covid-19, coronavirus, 2019-ncov, sars-cov2, and pandemic. Requirement consolidation and final agreement: By considering the results of the analysis done by the R&D partners, the list of requirements is further refined and consolidated.
Requirement analysis by R&D partners: The prioritized list of requirements is analyzed by the research. After this step, user case partners have ensured highest priority requirements, which will be implemented by R&D partners. Shall is used to denote essential requirements, which are of highest priority for validation of the wanted recommendation systems. To deal with such a challenge and thus mitigate the risks of developing systems that might not be in line with the user requirements, we developed proof-of-concept recommendation systems. We explain in detail the challenges we had to deal with, together with the related lessons learned when developing and evaluating these systems. In the following sections, such steps are described in detail. Without giving details on each tool’s inner technicalities, in the following sections, we focus on the challenges we faced while conceiving the CROSSMINER recommendation systems, and on the lessons that we learned on the way. Sections 3-5 discuss the challenges we had to address while conceiving the CROSSMINER recommendation systems. The methods we employed to address such challenges are presented together with the corresponding lessons learned. RLL1 – Importance of a clear requirement definition process: As previously mentioned, we managed to address Challenge RC1 through a tight collaboration with the use case partners. When realizing a new type of recommendation system, it is crucial to have a clear knowledge of the possible techniques and patterns that might be employed to develop new ones. RC1 – Clear understanding of the recommendation systems that are needed by the end users: Getting familiar with the functionalities that are expected from the final users of the envisioned recommendation systems is a daunting task.
For example, a developer may be interested in understanding which techniques are suitable for producing recommendations; or how to capture the developer’s context; or which is the most feasible way to present recommendation outcomes, to name a few. As shown in Fig. 1, the CROSSMINER components are conceptually in between the developer and all the different and heterogeneous data sources (including source code, bug tracking systems, and communication channels) that one needs to interact with when understanding and using existing open-source components. Such a process is time-consuming since the problem is not a lack, but in contrast, an overload of information coming from heterogeneous and rapidly evolving sources. We have applied such a process in different projects and we successfully applied it also for developing the recommendation systems that we identified in the context of the CROSSMINER project. You don’t want to lose projects just because you lack the developer skill of a specific common or emerging and growing language. To be concrete, the usage of the httpcomponent library allows the developer to access HTML resources by unloading the result state management and client-server authorization implementation on the library; meanwhile gson could provide a parallel way to crawl public Web data; finally introducing a logging library, i.e., log4j, can improve the project’s maintainability. This art icle was done by GSA C on te nt Generator DEMO !
Based on the project’s mining tools, developers can select open-source software and get real-time recommendations while working on their development tasks. Corresponding recommendations that the envisioned system should produce. Such artifacts were used as part of the requirements to implement the system able to resemble them. Other use case partners were asking for additional recommendations, which were posing requirements that might have had ripple effects on the other one’s. UserBased CF relies on explicit feedback coming from the users even though this approach suffers from scalability issues in case of extensive data. RLL3 – Importance of pilot applications: Using a pilot application can be beneficial to support the interactions between the final users and the developers of the wanted recommendation systems. The application can allow the involved parties to tailor the desired functionalities utilizing explanatory inputs. Our work can help to improve the experience of teams who are working remotely by helping identify crucial factors that they should focus on strengthening, such as the ability to effectively communicate and brainstorm, and the maintenance of social connection and team cohesion. Section 6 reviews the related work and finally, Section 7 sketches perspective work and concludes the paper. Outline of the paper: The paper is structured as follows: Section 2 gives an overview of the CROSSMINER project and the underpinning motivations. An overview of all the challenges. Present the lessons gained by overcoming the challenges.
