The invention relates to the technical field of knowledge maps, in particular to a financial derivative design method fusing
tea culture knowledge maps, which comprises the following steps of: identifying and extracting
tea culture entities and causal relationships in news and announcements, setting a head entity, a
tail entity, a relationship type and a
timestamp parameter for each event, obtaining a
time sequence event quadruple set, and setting a
time sequence event quadruple set; and connecting the independent tetrad according to the entity node and the
timestamp sequence shared in the
time sequence event tetrad set. For investment portfolio, associated nodes are extracted from a graph to define a narrative subject
community, random traversal between the nodes is carried out on a formed narrative sub-graph, so that the
coupling degree for measuring the narrative focus concentration degree is calculated, and the risk conduction intensity and the narrative
coupling degree are combined to determine the narrative focus concentration degree.
Tea culture entities are selected as underlying assets and derivative core terms are set, so that end-to-end conversion from unstructured text information to specific financial
tool design is realized.
