How does clustering (especially String clustering) work?

WebHere is one potential idea. Clustering involves some kind of similarity metric. You can compute a similarity between text documents (after some term weighting like TF-IDF you could use the cosine similarity for example). You can also compute a similarity between objects with categorical data. Matching coefficients are good option for this.
