Embodiment Construction

[0029] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention. It should be noted that in the following description, when detailed descriptions of known functions and designs may dilute the main content of the present invention, these descriptions will be omitted here.

[0030] A method for semantic compression coding of situational text messages based on TSS coding, the main process of the method is as follows figure 1 shown, including the following steps:

[0031] 1. First, for the input semantic text message, according to the text representation form of the semantic text message, the time information, space information, situational elements, and conjunctions and other words and phrases contained in the semantic message are segmented and marked, and the content elements of the semantic message are extracted. Framework, which decomposes t...

Abstract

The invention provides a situation text message semantic compression coding method based on TSS coding, belongs to the field of semantic situation text message compression coding, and carries out coding according to time elements, space elements and semantic elements contained in a situation text message. The method comprises the following steps: firstly, extracting key semantic element connotations in a to-be-compressed situation text semantic message, and then, firstly, constructing a situation semantic element coding scheme library and a coding scheme Bayesian decision model according to confrontation application fields related to various text messages for situation semantic elements in the to-be-compressed situation text semantic message; selecting a model by means of the constructed coding scheme to carry out semantic compression coding; aiming at the time semantic elements, constructing a two-stage coding strategy, and respectively coding the time reference and the time difference; for spatial semantic elements, a multi-level spatial address semantic system is constructed, and spatial mapping coding is performed on spatial semantics in various different expression modes such as longitude and latitude, place names and the like. According to the invention, redundant data can be removed, and the transmission data volume is reduced.

Description

technical field [0001] The invention belongs to the field of semantic situation text message compression coding, in particular to a method for semantic compression coding of situation text messages based on TSS coding. Background technique [0002] Semantic situation data often involves time-space domain data such as surveying and mapping, reconnaissance, and meteorology, and also contains rich business background knowledge related to application fields. When compressing and encoding situational text information, it is necessary to perform targeted encoding based on the data type of semantic elements and the frequency of use of semantic element phrases in a specific application field, so that the semantic data in the time-space domain of the hash distribution can be established through a unified encoding A strong association relationship can be established to realize efficient compression of temporal and spatial domain semantic situation data. [0003] For text, the traditi...
