A Graph Degeneracy-based Approach to Keyword Extraction
Antoine J.‐P. Tixier, Fragkiskos D. Malliaros, Michalis Vazirgiannis · 2016
We operate a change of paradigm and hypothesize that keywords are more likely to be found among influential nodes of a graph-ofwords rather than among its nodes high on eigenvector-related centrality measures.To test this hypothesis, we introduce unsupervised techniques that capitalize on graph degeneracy.Our methods strongly and significantly outperform all baselines on two datasets (short and medium size documents), and reach best performance on the third one (long documents).
