[0035] like figure 1 As shown, the new drug use prediction method based on multi-similarity fusion includes the following steps,
[0036] Step 1: Calculate drug similarity using drug chemical structure data, the formula is as follows:
[0037]
[0038] where sim s Indicates the similarity between drug a and drug b calculated using drug chemical structure data, D 1a Indicates the number of chemical structures contained in drug a, D 1b Indicates the number of chemical structures contained in drug b, |D 1ab |Indicates the number of identical chemical structures contained in drug a and drug b;
[0039] Step 2: Use the drug target protein data to calculate the drug similarity, the calculation formula is as follows:
[0040]
[0041] where sim p Indicates the similarity between drug a and drug b calculated using drug target protein data, D 2a Indicates the number of target proteins corresponding to drug a, D 2b Indicates the number of target proteins corresponding to d...
