Resumo
Cancer is a critical disease that affects millions of people and families around the world.
In 2012 about 14.1 million new cases of cancer occurred globally. Because of many
reasons like the severity of some cases, the side effects of some treatments and death
of other patients, cancer patients tend to be affected by serious emotional disorders,
like depression. Thus, the use of a behavioral tool that assists the detection of the
people mood can contribute to the monitoring of patients and family members during
treatment. Therefore, the objective of this work is to develop a Sentiment Analysis tool,
named SentiHealth-Cancer (SHC), to assist the detection of the emotional state of people
members of Brazilian virtual communities for support cancer patients. We conducted
a comparative study of the proposed method and a set of general-purpose Sentiment
Analysis tools. For this, we collected 789 messages of 8 Facebook communities and
considered 2.574 reviews of volunteers about the real sentiments expressed in these
messages. Thus, the performance of the tools were tested in each community, with
psychologists and non psychologists reviews and, where possible, with texts in Portuguese
and translated into English. The results showed that, overall, the proposed method
performance in this work is superior to other tools, both analyzing texts in Portuguese and
English. For example, its accuracy (56.64%) analyzing all messages shows a significant
increase of 11.78% compared to the greater accuracy (50.67%) presented by other tools.
