This paper presents a method for the generation of struc-
tured data sources for music recommendation using information extracted
from unstructured text sources. The proposed method identi es entities
in text that are relevant to the music domain, and then extracts seman-
tically meaningful relations between them. The extracted entities and re-
lations are represented as a graph, from which the recommendations are
computed. A major advantage of this approach is that the recommenda-
tions can be conveyed to the user using natural language, thus providing
an enhanced user experience. We test our method on texts from song-
facts.com, a website that provides facts and stories about songs. The
extracted relations are evaluated intrinsically by assessing their linguis-
tic quality, as well as extrinsically by assessing the extent to which they
map an existing music knowledge base. Finally, an experiment with real
users is performed to assess the suitability of the extracted knowledge for
music recommendation. Our method is able to extract relations between
pair of musical entities with high precision, and the explanation of those
relations to the user improves user satisfaction considerably. |
