| Abstract | In this paper, we present our work on constructing a textual semantic relationcorpus by making use of an existing treebank annotated with discourserelations. We extract adjacent text span pairs and group them into sixcategories according to the different discourse relations between them. Afterthat, we present the details of our annotation scheme, which includes sixtextual semantic relations, 'backward entailment', 'forward entailment','equality', 'contradiction', 'overlapping', and 'independent'. We also discusssome ambiguous examples to show the difficulty of such annotation task, whichcannot be easily done by an automatic mapping between discourse relations andsemantic relations. We have two annotators and each of them performs the tasktwice. The basic statistics on the constructed corpus looks promising: weachieve 81.17% of agreement on the six semantic relation annotation with a .718kappa score, and it increases to 91.21% if we collapse the last two labels witha .775 kappa score. |
