Match-Prompt: Improving Multi-task Generalization Ability for Neural Text Matching via Prompt Learning

Understand

Text matching is a fundamental technique in both information retrieval and natural language processing.

• Text matching tasks share the same paradigm that determines the relationship between two given texts.
• The relationships vary from task to task, e.g.~relevance in document retrieval, semantic alignment in paraphrase identification and answerable judgment in question answering.
• However, the essential signals for text matching remain in a finite scope, i.e.~exact matching, semantic matching, and inference matching.
