Approximate subgraph matching

Approximate subgraph matching

This video was recorded at First International Workshop on Knowledge Diversity on the Web, Hyderabad 2011. The paper presents an approach to detection of topic variations based on approximate graph matching. Text items are represented as semantic graphs and approximately matched based on a taxonomy of node and edge labels. Best-matching subgraphs are used as a template against which to align and compare the articles. The proposed approach is applied on news stories using WordNet as the predefined taxonomy. Illustrative experiments on real-world data show that the approach is promising.
