The embodiment of the invention provides a question and answer matching method and device, a model training method and device, equipment and a storage medium. The method comprises the steps that a first word sequence corresponding to a question and answer matching document is acquired, the question and answer matching document comprises a to-be-answered question and a text used for matching answers to the question, the first word sequence comprises at least two words, and each word comprises one or more characters; determining a target position for setting a character in the first word sequence; setting a character for representing an answer type at the target position to form a second word sequence; in the second word sequence, determining a starting position and an ending position of ananswer corresponding to the question; and determining answers matched with the corresponding questions according to the corresponding contents of the start position and the end position in the secondword sequence. Through the method and the device, the multi-answer type machine reading understanding task can be supported, so that the requirement of the user on the multi-answer type is met, and the user experience is improved.
Description
technical field [0001] The embodiments of the present application relate to the technical field of artificial intelligence, and relate to but are not limited to a question-answer matching method, a model training method, a device, a device, and a storage medium. Background technique [0002] With the development of artificial intelligence technology, machine reading comprehension technology has also been widely used. For example, machine reading comprehension technology will be used in multiple application scenarios such as web search, question answering robot and intelligent voice assistant. Usually, the answer output during machine reading comprehension includes multiple types, for example, fragment type, whether type and no answer type. [0003] The current machine reading comprehension technology is usually an extractive machine reading comprehension technology, that is, a part of the text used to match the answer to the question is extracted as the answer to the questio...
