  The dataset was collected to examine and identify possible key topics within
these texts. Data preparation such as data cleaning, transformation,
tokenization, removal of stop words from both English and Filipino, and word
stemming was employed in the dataset before feeding it to sentiment analysis
and the LDA model. The topmost occurring word within the dataset is
"development" and there are three (3) likely topics from the speeches of
Philippine presidents: economic development, enhancement of public services,
and addressing challenges. The dataset was able to provide valuable insights
contained among official documents. While the study showed that presidents have
used their annual address to express their visions for the country. It also
presented that the presidents from 1935 to 2016 faced the same problems during
their term. Future researchers may collect other speeches made by presidents
during their term; combine them to the dataset used in this study to further
investigate these important texts by subjecting them to the same methodology
used in this study. The dataset may be requested from the authors and it is
recommended for further analysis. For example, determine how the speeches of
the president reflect the preamble or foundations of the Philippine
constitution.
