We predict that sales levels are associated with two forms, respectively, of information inconsistency (confliction and competition) and consistency (confirmation and complementary) often found in product and service reviews. For our investigation, we classified information contained in tablet computer reviews as conflicting, competing, confirming, or complementing using BERT (Bidirectional Encoder Representations from Transformers) and word2vec (Word to Vector) techniques. Estimating an aggregated-level sales rank model over a 24-week period on reviews and sales data obtained from Amazon, we show that variations in tablet sales can be partially explained with our information classification. These findings provide new insights for user-generated content research.}, language = {en} }
