    Hi @elena2020chao

     

    For your first question: 

     

    Not sure why you explicitly need to predict a cluster.  

     

    Clustering algorithm adds cluster labels to the data, then it is possible to built for example a decision tree model over these labels, this way you can predict a cluster label for the new text. 

     

    But also consider the simplest and most straightforward way (especially if you don't have many texts), in which you just add a new text to your corpus and then run clustering algorithm over it once again, this way new text will be assigned to one of the clusters.
