Abstract

The present invention relates to a method for judging the phylogeny among species using the three-branch concept, comprising the following steps: (1) analyzing the original biological information system ( U , V , R ) to be processed to obtain the biological information system ( U 3 , V 3 , R 3 ); (2) For the processed biological information system ( U 3 , V 3 , R 3 ) to extract the three concepts; (3) For the obtained three concepts, use the three concept lattice theory to analyze each of the three concepts to determine whether there is a relationship between species and the degree of support for the relationship between species. The present invention is a method for analyzing species kinship based on a new form of concept lattice theory—three-branch concept lattice theory. The present invention introduces the three-branch concept into the analysis of species kinship, and can not only analyze species having kinship, It does not have kinship, and it can also analyze the kinship between species, which further refines the kinship analysis theory and helps researchers understand the kinship of species at a deeper level.

Description

technical field [0001] The invention relates to a method for analyzing the phylogeny of species, in particular to a method for judging the phylogeny among species by using the concept of three clades. Background technique [0002] Phylogenetic analysis is a method for studying the evolution of species and the systematic classification of species. The research objects are biological sequences carrying genetic information. At present, specific mathematical statistical algorithms are often used to calculate the phylogenetic relationship between species, and the phylogenetic tree is used to summarize the relationship between species. [0003] In 2014, Qi Jianjun and others proposed a new formal concept in the article "Three-way formal concept lattice" in the collection "Rough Sets and Knowledge Technology" published by Springer International Publishing in Switzerland: three concepts, specifically divided into: There are three concepts derived from objects (X, (N, B)) and three ...
