METHOD AND SYSTEM FOR DISCOVERING RELATED BOOKS BASED ON BOOK CONTENT

摘要

System and method for determining book similarities based on text content and thereby discovering related books for recommending to customer-users. Each book is associated with a probability distribution on a set of topics that is derived from text content of the book against the set of topics. The pair-wise distances of the probability distributions between corresponding books are computed to derive similarities thereof. The probability distributions may be generated by leveraging a text topic model that defines a set of topics, a respective set of relevant terms under each topic, and a probability distribution on each set of relevant terms. The text topic model may be automatically generated by processing content of a corpus of training books via a training process.
