“…The classical works of Weiser (1999) , Satyanarayanan (2001) , and Dey, Abowd & Salber (2001) defined the ubiquitous computing and context-aware computing. Since then, these concepts have been applied in different knowledge areas such in health ( Vianna & Barbosa, 2014 ; Vianna & Barbosa, 2019 ; Dias et al, 2020 ; Petry et al, 2020 ; Bavaresco et al, 2020 ), well-being ( Vianna, Barbosa & Pittoli, 2017a ), competence management ( Rosa et al, 2015 ), learning ( Barbosa et al, 2011 ; Wagner, Barbosa & Barbosa, 2014 ; Barbosa et al, 2014 ; Larentis et al, 2020 ), commerce ( Barbosa et al, 2016 ), accessibility ( Tavares et al, 2016 ; Barbosa et al, 2018 ), Smart Cities ( Rolim et al, 2016 ; Orrego & Barbosa, 2019 ; Matos et al, 2021 ), and agriculture ( De Souza et al, 2019 ; Bhanu, Reddy & Hanumanthappa, 2019 ; Helfer et al, 2020 ). The application of ubiquitous computing in project management coined the term Ubiquitous Project Management ( Filippetto et al, 2020 ).…”

The growing technological advance is causing constant business changes. The continual uncertainties in project management make requirements engineering essential to ensure the success of projects. The usual exponential increase of stakeholders throughout the project suggests the application of intelligent tools to assist requirements engineers. Therefore, this article proposes Nhatos, a computational model for ubiquitous requirements management that analyses context histories of projects to recommend reusable requirements. The scientific contribution of this study is the use of the similarity analysis of projects through their context histories to generate the requirement recommendations. The implementation of a prototype allowed to evaluate the proposal through a case study based on real scenarios from the industry. One hundred fifty-three software projects from a large bank institution generated context histories used in the recommendations. The experiment demonstrated that the model achieved more than 70% stakeholder acceptance of the recommendations.

Distance learning has assumed a relevant role in the educational scenario. The use of Virtual Learning Environments contributes to obtaining a substantial amount of educational data. In this sense, the analyzed data generate knowledge used by institutions to assist managers and professors in strategic planning and teaching. The discovery of students’ behaviors enables a wide variety of intelligent services for assisting in the learning process. This article presents a literature review in order to identify the intelligent services applied in distance learning. The research covers the period from January 2010 to May 2021. The initial search found 1316 articles, among which 51 were selected for further studies. Considering the selected articles, 33% (17/51) focus on learning systems, 35% (18/51) propose recommendation systems, 26% (13/51) approach predictive systems or models, and 6% (3/51) use assessment tools. This review allowed for the observation that the principal services offered are recommendation systems and learning systems. In these services, the analysis of student profiles stands out to identify patterns of behavior, detect low performance, and identify probabilities of dropouts from courses.
