The invention discloses a water conservancy intelligent question-answering
system and method based on knowledge enhancement and data driving, and aims at water conservancy business structured and
unstructured data query, through
loop optimization driven by positive and negative examples, precise classification of secondary intentions of water conservancy problems is realized, knowledge
questions and answers,
data query and professional water conservancy subclass
questions and answers can be distinguished, and the
system and the method can be applied to water conservancy business. And the semantic analysis efficiency is improved. Aiming at the problem of low query accuracy of retrieval enhancement generation in the field of water conservancy, a differential water conservancy
knowledge base oriented to professional books, industrial standards and laws and regulations is constructed, local and networking information is processed through a multi-source knowledge fusion and conflict resolution mechanism, and the accuracy,
interpretability and
traceability of question and answer content are improved. Aiming at the problems of complex operation and low
semantic query accuracy in query of massive water conservancy
business data and
monitoring data, multi-layer constraint Text-to-
SQL conversion is performed based on water conservancy
business knowledge, high-precision
semantic query and automatic visual output of water conservancy structured data are realized, and query efficiency is improved.
