Automatic thematic classification of election manifestos

作者:

Highlights:

• We digitized political texts from the 1980s and 1990s.

• We used these data to learn a classifier that can label more recent political texts.

• Change of themes over the years affects recall of the learned classifier.

• But precision is comparable to the precision obtained by a human expert labeller.

• For political themes, a high level of detail seems to be preferred by domain experts.
