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 Gigaword corpus and TimeBank Corpus. Whereas, in Paper 2 Google is used to find number of hits for relation verb pair and surface pattern from WWW. Similarly other hits are also found using Google.

Both papers address different problems. Though approaches inspired my mutual information are used in some way in both papers.
