  Have you ever looked at a painting and wondered what is the story behind it?
This work presents a framework to bring art closer to people by generating
comprehensive descriptions of fine-art paintings. Generating informative
descriptions for artworks, however, is extremely challenging, as it requires to
1) describe multiple aspects of the image such as its style, content, or
composition, and 2) provide background and contextual knowledge about the
artist, their influences, or the historical period. To address these
challenges, we introduce a multi-topic and knowledgeable art description
framework, which modules the generated sentences according to three artistic
topics and, additionally, enhances each description with external knowledge.
The framework is validated through an exhaustive analysis, both quantitative
and qualitative, as well as a comparative human evaluation, demonstrating
outstanding results in terms of both topic diversity and information veracity.
