Shall I use ordinal encoding or One-Hot-Encoding when using DBSCAN for content clustering on websites?
With the information you provide, I suggest you can use both and test based upon a metric like Siluhette Score or Davis Bouldin index to measure the quality of your clusters when using either of both preprocessing techniques. In this way, you will have an objective metric to compare between the two preprocessing techniques and keep the one that maximizes the chosen metric since it means you are taking the preprocessing that generates better-formed clusters
