Co-occurrence graphs for word sense disambiguation in the biomedical domain

作者:

Highlights:

• Co-occurrence graphs provide competitive results in biomedical WSD.

• The proposed approach reduces the use of external resources to a minimum.

• Evaluation on the NLM-WSD test dataset overcomes knowledge-base state-of-the-art systems.

• Less restrictive graphs, which avoid the removal of important edges, lead to better results.

• Convergence is fast as the number of documents used for building the graph increases.
