Pablo Calleja, Freddy Priyatna, Nandana Mihindukulasooriya, Mariano Rico

Abstract: We present DBtravel, a tourism-oriented knowledge graph generated from the collaborative travel site Wikitravel. Our approach takes advantage of the recommended guideline for contributors provided by Wikitravel and extracts the named entities available in Wikitravel Spanish entries by using a NLP pipeline. Compared to a manually annotated gold standard, results show that our approach reaches values for precision and recall around 80% for some sections of Wikitravel for the Spanish language.
