The Web Conference 20202020Virtual assistants such as Amazon Alexa, Apple Siri, and Google Assistant often rely on a semantic parsing component to understand which action(s) to execute for an utterance spoken by its users. Traditionally, rule-based or statistical slot-filling systems have been used to parse “simple” queries — that is, queries that contain a single action and can be decomposed into a set of non-overlapping entities

ICASSP 20202020In this work, we investigated the teacher-student training paradigm to train a fully learnable multi-channel acoustic model for far-field automatic speech recognition (ASR). Using a large offline teacher model trained on beamformed audio, we trained a simpler multi-channel student acoustic model used in the speech recognition system. For the student, both multi-channel feature extraction layers and the

The Web Conference 20202020A knowledge graph (e.g., Freebase, YAGO) is a multi-relational graph representing rich factual information among entities of various types. Entity alignment is the key step towards knowledge graph integration from multiple sources. It aims to identify entities across different knowledge graphs that refer to the same real-world entity. However, current entity alignment systems overlook the sparsity of different

CHIIR 20202020Query intent prediction is a component of information retrieval which improves result relevance through an understanding of latent user intents in addition to explicit query keywords. We target context-of-use intents, such as the activity for which a product is used and the target audience for a product, which are subjective and not usually indexed as product attributes in the catalog. We describe a method

The Web Conference 20202020Learning a ranking model in product search involves satisfying many requirements such as maximizing the relevance of retrieved products with respect to the user query, as well as maximizing the purchase likelihood of these products. Multi-Objective Ranking Optimization (MORO) is the task of learning a ranking model from training examples while optimizing multiple objectives simultaneously. Label aggregation
