Resumo
The continuous development of technology and its dissemination in all domains have
caused significant changes in society and in education. The new global society demands
new skills and provides an opportunity to introduce new technologies into the educational
process, improving traditional education systems. The focus should be on the search for
information, significant research, and on the development of projects, rather than on the
pure transmission of content. When delivering a lecture about a given content, teachers
often provide additional sources that will help students deepen their understanding of the
subject and carry out activities. Furthermore, it is desirable to have proactive students,
capable of interpreting and identifying other sources of information that complement and
expand the subject being studied. However, one of the challenges today is information
overload - there are many documents available and few effective ways to treat them.
Every day, large numbers of documents are stored and made available. These documents
contain a lot of relevant information. However finding that knowledge is a difficult
task. The BOOKISH system, proposed in this work, assists students in their search
activity. Analyzing PowerPoint slide presentations, the tool identifies contextually similar
electronic documents, minimizing the time spent in searching for additional relevant
material and directing the student to the content he needs. The tool presented in this
document uses text mining techniques and automatic query expansion.
