identified in the conferences is that these two terms have a decreased interest along
this period, and the other eight terms have a constant average. Some of the most
cited terms at conferences (education and development) are not among the ones of
greatest interest in searches in the analyzed period.
From the Similitude Analysis (Fig. 3), based on the graph theory, performed with
the aid of the Iramuteq software, it is possible to identify the connections between
words, which helps to identify the structure of the content of the textual corpus.
Five words that stand out in the articles were identified: development, university,
education, and learn. From them, terms like environment, system, knowledge, model,
cooperation, sustainable, student, mobile, and technology, branch out.
In Fig. 3, it is possible to see some of the themes of the articles most cited in the
selected sample: mobile application development for environment monitoring, international development and sustainability, dissemination of sustainable development
on universities’ websites, education for social innovation, cooperation and human
development, cooperation between businesses and universities, computer science
and environmental engineering, and environmentally friendly travel behavior.
