Problems solved by technology

In addition, spatial patterns with similar spatial semantic information do not necessarily have similar spatial activity places, for example, the same office worker, but the work unit and residence may not be the same, which brings difficulties to the measurement of spatial patterns with similar spatial semantic information

Embodiment Construction

[0032] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0033] see figure 1 The method for identifying the semantic pattern of spatial motion behavior provided by the embodiment of the present invention is characterized in that it includes the following steps:

[0034] Step S1, collecting and judging stay behavior based on spatial positioning;

[0035] Step S2, establishing a mathematical description and visual expression of the stay behavior, and establishing a spatial behavior semantic pattern map;

[0036] Step S3, performing spatial behavior similarity measurement or spatiotemporal frequent pattern mining ba...

Abstract

The invention discloses an identification method of a spatial motion behavior semantic pattern. The method comprises the following steps that a stay behavior based on spatial location is collected andjudged; a mathematical description and a visualize expression of the stay behavior are established, a spatial behavior semantic pattern map is established; spatio temporal frequent pattern mining based on the spatial behavior semantic pattern map is conducted. The spatial behavior pattern mapping mechanism and metric calculation method proposed in this method provide a foundation for discoveringspatial semantic information. Because of the regularity of statistical distribution of the spatial behavior patterns fits the internal expressions of spatial behaviors of different occupational groups, through the method, people can indirectly understand the activity purpose and the motivation of a traveler, especially an unusual and dangerous behavior, in the hidden behavior patterns, hidden secret relationships are revealed which are valuable for social security prevention and control, therefore, the application of social security and actual combat based on spatial motion big data abnormal behavior monitoring becomes possible.

Description

technical field [0001] The invention belongs to the technical field of data analysis, and relates to a space motion data analysis technology, in particular to a method for identifying a semantic pattern of a space motion behavior. Background technique [0002] Human beings carry out various spatial behavior activities every day, such as going to the unit to work and shopping in the store. Because human beings' spatial behaviors are purposeful or task-driven, they show group-related regularity, and people with different occupations and identities show different spatial behavior characteristics. Most of the people who go out early and return late are office workers. A loitering might be a thief. In criminal activities that endanger national and social security, criminals usually go to the scene to repeatedly step on the spot out of the need to find the best time to commit the crime and plan escape routes. This is also a characteristic of space behavior activities with strong ...
