Resumen
OPINIONS ABOUT ITEM?S ASPECTS IN USER REVIEWS MAY BE A VALUABLE SOURCE OF INFORMATION FOR IMPROVING RECOMMENDER SYSTEMS PERFORMANCE. DESPITE IMPORTANT ADVANCES IN NATURAL LANGUAGE PROCESSING AND MACHINE LEARNING FIELDS THAT ALLOW THE EXTRACTION OF SUCH INFORMATION FROM TEXTS WRITTEN IN ENGLISH, THERE IS STILL WORK TO DO IN THE CASE OF TEXTS IN OTHER LANGUAGES. IN THIS WORK, WE ADAPT KNOWN UNSUPERVISED ASPECT EXTRACTION APPROACHES TO EXTRACT OPINIONS FROM REVIEWS WRITTEN IN SPANISH. OUR RESULTS SHOW THAT THE EXPLOITATION OF ASPECTS EXTRACTED AUTOMATICALLY FROM REVIEWS WRITTEN IN SPANISH ALLOW TO IMPROVE CONSIDERABLY THE TOP-K RECOMMENDATION LISTS GENERATED BY ASPECT-BASED RECOMMENDER SYSTEMS.
