TP-Link: Fine-grained Pre-Training for Text-to-SQL Parsing with Linking Information

COLING 2024main

In this paper, we introduce an innovative pre-training framework TP-Link, which aims to improve context-dependent Text-to-SQL Parsing by leveraging Linking information. This enhancement is achieved through better representation of both natural language utterances and the database schema, ultimately…

Disentangled CVAEs with Contrastive Learning for Explainable Recommendation

AAAI 2023technical

Modern recommender systems are increasingly expected to provide informative explanations that enable users to understand the reason for particular recommendations. However, previous methods struggle to interpret the input IDs of user--item pairs in real-world datasets, failing to extract adequate ch…

HypeR: Multitask Hyper-Prompted Training Enables Large-Scale Retrieval Generalization

ICLR 2023poster

Recently, large-scale text retrieval has made impressive progress, facilitating both information retrieval and downstream knowledge-intensive tasks (e.g., open-domain QA and dialogue). With a moderate amount of data, a neural text retriever can outperform traditional methods such as BM25 by a large…

Multi-Scale Distribution Deep Variational Autoencoder for Explanation Generation

ACL 2022findings

Generating explanations for recommender systems is essential for improving their transparency, as users often wish to understand the reason for receiving a specified recommendation. Previous methods mainly focus on improving the generation quality, but often produce generic explanations that fail to…

STAR: SQL Guided Pre-Training for Context-dependent Text-to-SQL Parsing

EMNLP 2022finding

In this paper, we propose a novel SQL guided pre-training framework STAR for context-dependent text-to-SQL parsing, which leverages contextual information to enrich natural language (NL) utterance and table schema representations for text-to-SQL conversations. Concretely, we propose two novel pre-tr…
