Measuring Prerequisite Relations Among Concepts

A prerequisite relation describes a basic relation among concepts in cognition, education and other areas. However, as a semantic relation, it has not been well studied in computational linguistics. We investigate the problem of measuring prerequisite relations among concepts and propose a simple link-based metric, namely reference distance (RefD), that effectively models the relation by measur...

Total Rank Distance And Scaled Total Rank Distance: Two Alternative Metrics In Computational Linguistics

In this paper we propose two metrics to be used in various fields of computational linguistics area. Our construction is based on the supposition that in most of the natural languages the most important information is carried by the first part of the unit. We introduce total rank distance and scaled total rank distance, we prove that they are metrics and investigate their max and expected value...

Linguistic Distances

In many theoretical and applied areas of computational linguistics researchers operate with a notion of linguistic distance or, conversely, linguistic similarity, which is the focus of the present workshop. While many CL areas make frequent use of such notions, it has received little focused attention, an honorable exception being Lebart & Rajman (2000). This workshop brings a number of these s...

Computational Semantics

The most central fact about natural language is that it has meaning. Semantics is the study of meaning. In formal semantics, we conduct this study in a formal manner. In computational semantics, we’re additionally interested in using the results of our study when we implement programs that process natural language. In this course, we show how formal semantic representations can be computed and ...
