While specifying an IoT-based system, software developers have to face a set of challenges, spanning from selecting the hardware components to writing the actual source code. Even though dedicated development environments are in place, a nonexpert user might struggle with the over-choice problem in selecting the proper component. By combining MDE and recommender systems, this paper proposes an initial prototype, called ResyDuo, to assist Arduino developers by providing two different artifacts, i. e. , hardware components and software libraries. In particular, we make use of a widely adopted collaborative filtering algorithm by collecting relevant information by means of a dedicated data model. ResyDuo can retrieve hardware components by using tags or existing Arduino projects stored on the ProjectHub repository. Then, the system can eventually retrieve corresponding software libraries based on the identified hardware devices. ResyDuo is equipped with a web-based interface that allows users to easily select and configure the under-developing Arduino project. To assess ResyDuos performances, we run the ten-fold crossvalidation by adopting the grid search strategy to optimize the hyperparameters of the CF-based algorithm. The conducted evaluation shows encouraging results even though there is still room for improvement in terms of the examined metrics. |
