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, method and dataset

Goal of first paper was 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.

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

Paper 1 uses a Gigaword corpus for training. Whereas, in Paper 2 Google is used to find number of hits for relation verb pair $V1,V2$ and surface pattern $P$ from WWW. Similarly other hits are also found using Google.
