... are often being manifested by several different patterns. In this paper, unlike the majority of studies that use patterns in order to find instances of given rela- tionships, we use sets of patterns ... sets of pairs into several clusters, where each cluster corresponds to one of a known set of re- lationship types. Their classification setting is thus very different from our unsupe...
