Task 2: Measuring Degrees of Relational Similarity

Use the main menu ≡ to select a topic.

The task is, given two pairs of words, A:B and C:D, determine the degree to which the semantic relations between A and B are similar to those between C and D. Unlike the more familiar task of semantic relation identification, which assigns each word pair to a discrete semantic relation class, this task recognizes the continuous range of degrees of relational similarity. The challenge is to determine the degrees of relational similarity between a given reference word pair and a variety of other pairs, mostly in the same general semantic relation class as the reference pair.
