Replacements of Rare Herbs and Simplifications of Traditional Chinese Medicine Formulae Based on Attribute Similarities and Pathway Enrichment Analysis

Table 3

Functions and 𝐷_𝑖,𝑗 of herb 𝑖 and herb 𝑗.

Herb 𝑖	Function 1	Function 2	Function 3	Function 4	Function 5
Herb 𝑗	Function 2	Function 4	Function 6	Function 7

 ^∗Assuming herb 𝑖 has 5 functions and herb 𝑗 has 4 functions. Function 2 and Function 4 are shared functions. So 𝐷_𝑖,𝑗 is calculated as 𝐷_𝑖,𝑗 = (2∗2)/(5+4)≈0.44.
