... in our case looking for same head expressions and appositive constructions, both of them requiring only constant time. On the other hand, unique expressions always have the same or similar form: ... Bayes, and many others. On the contrary, algorithms, providing tree- or rule -based classifications (for example, C4.5 and Ripper) would fulfil our first requirement ideally. Second, we wa...
