Clustering: try to find own categories and put documents that match in it. You group all documents with minimal distance together.
Would I be correct to say that you have to define a "distance threshold"
parameter in order to define when to build a new category for a certain
group?
Depends on the type of clustering algorithm. Some clustering algorithms take the number of clusters as a parameter (in this case the algorithm may be run several times with different values, to determine the best value). Other types of algorithms, such as hierarchical agglomerative clustering algorithms, work more as you suggest.
