The growing popularity of Virtual Assistants poses new challenges for Entity Resolution, the task of linking mentions in text to their referent entities in a knowledge base.Specifically, in the shopping domain, customers tend to mention the entities implicitly (e.g., "organic milk") rather than use the entity names explicitly, leading to a large number of candidate products.Meanwhile, for the same query, different customers may expect different results.For example, with "add milk to my cart", a customer may refer to a certain product from his/her favorite brand, while some customers may want to re-order products they regularly purchase.Moreover, new customers may lack persistent shopping history, which requires us to enrich the connections between customers through products and their attributes.To address these issues, we propose a new framework that leverages personalized features to improve the accuracy of product ranking.We first build a cross-source heterogeneous knowledge graph from customer purchase history and product knowledge graph to jointly learn customer and product embeddings.After that, we incorporate product, customer, and history representations into a neural reranking model to predict which candidate is most likely to be purchased by a specific customer.Experiment results show that our model substantially improves the accuracy of the top ranked candidates by 24.6% compared to the state-of-theart product search model.* * This work was done when the first author was on an internship at Amazon Alexa AI. * [8] blue diamond almonds, bold wasabi & soy sauce, 16 ounce (pack of 1) * epsoak epsom salt 19 lb.bulk bag magnesium sulfate usp * [2] blue diamond almonds variety pack (1.5 ounce bags) (20 pack) * blue diamond almonds, bold wasabi & soy sauce, 16 ounce (pack of 1) * [1] blue diamond almonds bold wasabi & soy sauce almonds, 25 ounce (pack of 1) * signature trail mix, peanuts, m & m candies, raisins, almonds & cashews, 4 lb * [6] blue diamond almonds, bold wasabi & soy, 1.5 ounce (pack of 12) * amazon brand -happy belly nuts, chocolate & dried fruit trail mix, 48 ounce Our model promotes candidate 8 which is previously purchased, whereas the customer selects another size.#5 cacao powder * [5] anthony's organic cocoa powder, 2 lb, batch tested and verified gluten free & non gmo * anthony's organic cocoa powder, 2 lb, batch tested and verified gluten free & non gmo * [1] viva naturals #1 best selling certified organic cacao powder from superior criollo beans, 1 lb bag * vör all natural keto nut butter spread (10oz) | only two ingredients | no sugar, no salt | vegan ... * [2] navitas organics cacao powder, 16oz.bag -organic, non-gmo, fair trade, gluten-free * anthony's organic cocoa powder, 2 lb, batch tested and verified gluten free & non gmo * [3] terrasoul superfoods raw organic cacao powder, 1 lb -raw | keto | vegan * nutiva organic, neutral tasting, steam refined coconut oil from non-gmo, sustainably farmed coconuts ... * [4] viva naturals certified organic cacao powder (2lb) for smoothie, coffee and drink mixes Our model promote "Anthony's Organic Cocoa Powder" as it has been purchased twice by the customer.
