We test our hypothesis on different RC tasks in the computational linguistic domain in which some RC task, like SemEval-2018 task 7 (Gábor et al., 2018), aims to classify relations, such as USAGE, TOPIC and MEDOL-FEATURE, and other task, like RC on RANIS dataset (Tateisi et al., 2014), asks for identifying relations such as INPUT and OUTPUT.
we come up with four 2 types of TSS, as shown in the first column of Table 1, for distinguishing these relations for a given specific task.
