I am working on text mining (reading book...) author said word association mining is actually the generalization of n-gram language model Can you please tell how word association mining is generalization of n-gram language model. For Me word association mining is finding symptomatic relation (finding co-occurring) words and n-gram language model is compare all n-words in query to suggest or return relevant documents.
Association rule mining will try to cover frequent concurrences of arbitrary length.
If you apply this (not just two term correlations) to text, you would indeed find n-grams without a fixed n.
