 Find the most relevant SDGs in the provided texts and computes the association of each text with the SDGs using the pre-trained fine-tuned model and the method of keywords extraction. The formula of the association is 
 
 ```math
-Association = \left\{
+{r}_{SDG} = \left\{
 \begin{array}{ll}
       0.7*probability + 0.3*avg\_cosine\_similarity  & \text{,for SDGs 1-16} \\
       0.5*avg\_cosine\_similarity  & \text{,for SDG 17} \\
