The Web Conference 2021 Workshop on Knowledge Management in E-Commerce2021Learning To Rank (LTR) models are a crucial component for the relevance ranking in e-commerce applications. When properly trained, the LTR models yield state-of-the-art ranking performance. A popular approach to training the LTR models involves minimizing a loss over historical customer interactions. Historical customer interactions are preferred over manually annotated data since the latter is costly to

NAACL 20212021In recent years online shopping has gained momentum and became an important venue for customers wishing to save time and simplify their shopping process. A key advantage of shopping online is the ability to read what other customers are saying about products of interest. In this work, we aim to maintain this advantage in situations where extreme brevity is needed, for example, when shopping by voice. We

NAACL 20212021In goal-oriented dialogue systems, users provide information through slot values to achieve specific goals. Practically, some combinations of slot values can be invalid according to external knowledge. For example, a combination of “cheese pizza” (a menu item) and “oreo cookies” (a topping) from an input utterance “Can I order a cheese pizza with oreo cookies on top?” exemplifies such invalid combinations

NAACL 20212021In recent years, incorporating external knowledge for response generation in open-domain conversation systems has attracted great interest. To improve the relevance of retrieved knowledge, we propose a neural entity linking (NEL) approach. Different from formal documents such as news, conversational utterances are informal and multi-turn, which makes it more challenging to disambiguate the entities. Therefore

NAACL 20212021In dialog systems, the Natural Language Understanding (NLU) component typically makes the interpretation decision (including domain, intent and slots) for an utterance before the mentioned entities are resolved. This may result in intent classification and slot tagging errors. In this work, we propose to leverage Entity Resolution (ER) features in NLU reranking and introduce a novel loss term based on ER
