Abstract

The invention discloses a multi-model collaborative question-answering method and system for the field of hydraulic cylinders. The method comprises the following steps: constructing a knowledge graph of the field of the hydraulic cylinders; receiving a hydraulic cylinder field problem input by a user, calculating a comprehensive score of the hydraulic cylinder field problem, judging whether the problem belongs to a query type problem or not according to the comprehensive score, if so, matching a template from a preset cross-layer query template library according to a semantic vector of the problem, and if not, matching the template; automatically generating a query statement adaptive to the current problem by combining a component parameter-assembly relationship-design specification three-level association path in the hydraulic cylinder domain knowledge graph, submitting the query statement to a database to execute query, and storing a query result; otherwise, judging whether the problem belongs to a calculation type problem according to the comprehensive score, if so, extracting key parameters in the problem, and calling a calculation program library according to the key parameters to complete calculation to obtain a calculation result; otherwise, integrating the query result and / or the calculation result, and generating an answer of the question.
