Such used build online search engines for highly specific retrieval. The current invention discloses a novel approach extract from raw text based on natural language processing (NLP) graph theoretic algorithm. method applied, example, protein-protein biomedical literature. extended other biological between terms as proteins, genes, pathways, diseases drugs. also applied domains relationships.
