Comparing Unsupervised Learning of Narrative Event Chains and Mining the web for fine-grained semantic verb relations

Papers

1. Unsupervised Learning of Narrative Event Chains, by N. Chambers, D. Jurafsky. [1]

2. VerbOcean:Mining the Web for Fine-Grained Semantic Verb Relations, by T. Chklovski, P. Pantel. [2]

Problem

Goal of first paper is to extract narrative event chains using unsupervised methods. Whereas, goal of second paper is to find the relation between verbs. Relations considered in second paper are similarity, strength, antonymy, enablement, and temporal relations.

Method

Paper 2 uses approach motivated by mutual information to compute strength of relation between verb pairs and surface pattern. Paper 1 uses mutual information motivated approach to induce narrative events. It uses Support Vector Machines temporal ordering of connected events.

Dataset

Paper 1 uses a Gigaword corpus. Whereas, in Paper 2 Google is used to find number of hits for relation verb pair $V1,V2$ and surface pattern $P$.
