Embodiment Construction

[0049] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0050] At present, the evaluation of urban work mainly relies on expert experience. Obviously, this method will be greatly affected by human factors, and it is not automatic and intelligent enough.

[0051] Based on the above technical problems, the embodiment of the present application provides a fusion map construction method, such as figure 1 As shown, the method includes the following steps:

[0052] Step 101, acquire event text from various information sources. ...

Abstract

The invention discloses a fusion graph construction method and device. The method comprises the steps of obtaining event texts from information sources; for any event text, determining an event group with a causal relationship in the event text through a machine learning algorithm, and determining causal strength between a reason event and a result event in the event group; determining an event atlas according to each event group and the causal strength between the reason event and the result event in each event group; and constructing a graph relationship through each event group in the event graph and an entity in the knowledge graph, thereby forming a fusion graph. According to the mode, city work is evaluated by using the knowledge graph fused with the event graph, dependence on expert experience can be avoided, and the city situation can be monitored or evaluated only according to the incidence relation between the events occurring in the city operation process and the knowledge graph.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a method and device for constructing a fusion map. Background technique [0002] With the continuous development and progress of science and technology, the construction of smart cities has become one of the driving forces of current technological innovation. Building a smart city requires not only effective storage, calculation, and analysis of massive urban data, but also the need to mine potential value from massive urban data, explore the laws of urban operation, and provide strong support for urban operational decision-making. [0003] However, in the process of building a smart city, especially when evaluating urban work, it mainly relies on expert experience. That is to say, after obtaining and preprocessing a large amount of urban data, it will be handed over to professionals engaged in urban management and planning, who will analyze the...
