Embodiment Construction

[0042] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0043] Explanation of terms:

[0044] Fusion of trends and situations: Fusion of trends and situations refers to the fusion calculation of trend data (a message composed of textual description text) and situation data (a message that focuses on the target and surrounds the sea situation). Association, to calculate the coupling degree in time, space and other dimensions, and perform association processing.

[0045] Hotspot areas: This article focuses on describing the environmental areas of the naval battlefield, aiming at areas with high importance, high density, and high frequency of the naval battlefield as hotspot areas.

[0046] see figure 1 As shown, the embodiment of the present invent...

Abstract

The invention discloses a hot spot area calculation method based on trend situation fusion. The hot spot area calculation method comprises the following steps: carrying out blocking processing on situation message data to construct a panoramic sparse statistical matrix; carrying out blocking calculation on the panoramic sparse statistical matrix based on Spark to obtain sparse matrix subset statistical results of a plurality of time slices; grouping and aggregating the sparse matrix subset statistical results of the plurality of time slices to obtain sparse matrix statistical results of a plurality of single time slices; selecting the sparse matrix statistical results of the plurality of single time slices according to a statistical request to perform fragmentation synthesis to obtain a situation hotspot region; identifying a plurality of trend entities in trend message data and associating the trend entities with situation entities; acquiring space-time activity areas of the trend entities according to time labels of the trend entities; drawing a trend situation hotspot area distribution map according to situation hotspot areas and the space-time activity areas of the trend entities. According to the method, the overall situation of sea battlefields can be effectively associated and found in mass situation data and high-quality trend data.

Description

technical field [0001] The invention belongs to the field of computer technology, and in particular relates to a calculation method and device, electronic equipment, and a storage medium for calculating a hotspot area based on fusion of trends and situations. Background technique [0002] In recent years, in the face of the increasing number of behaviors of some countries using the slogan of freedom of navigation and the issue of ownership of sea areas as an excuse, the situation facing my country's naval battlefield environment has gradually become severe. With the continuous enhancement of the country's comprehensive strength, more attention has been paid to the sovereignty of the country's territorial waters, especially the ability to analyze the naval battlefield environment. [0003] At present, there are many ways to obtain the track information of mass ship target activities through detection means, but with the increase of data volume, the technical means of single t...
