Embodiment Construction

[0080] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0081] refer to Figure 1 to Figure 5 , the present invention provides a layered fusion reading comprehension method across document long texts, comprising steps:

[0082] S1. Encoding the question, document, and question category respectively through the question, document, and question category encoding modules to obtain corresponding question representations and document representations, wherein the document representations include question-related information;

[0083] S2. Through the multi-step reasoning and multi-document extraction module, the question representation and document representation are based on the self-attention mechanism to obtain the question integration vector and the document integration vector, and the extraction repr...

Abstract

The invention relates to a cross-document long text layered fusion reading understanding method and system. The reading understanding system comprises a question and multi-document coding module, an attention-based joint augmented representation module, a multi-step reasoning and multi-document extraction module, a multi-document long text answer extraction and multi-step fusion module, a questionclassification module and other multi-task learning modules. According to the method, through deep pre-trained joint augmented representation, encoding and information fusion are carried out on problems and documents, a multi-step reasoning mechanism is used for extracting and fusing the documents, the information discretization problem of cross-document long texts can be solved, and the reasoning capability of multi-document reading understanding is improved.

Description

technical field [0001] The invention relates to the field of classification and processing of natural language texts, in particular to a method and system for layered fusion reading comprehension of cross-document long texts. Background technique [0002] With the development of information technology and the explosive growth of information, higher requirements are put forward for the integration and induction of information. In human-computer interaction scenarios, from retrieval to reasoning, from single document to multi-document, from single answer to multi-answer fusion, facing more complex scenarios, machine reading comprehension ability is an important standard to reflect human-machine intelligence, and it has also become a research topic. hotspots. [0003] Machine reading comprehension aims at that computers, like human beings, have the ability to read materials composed of natural language and to be able to reason and answer questions raised. In today's highly de...
