Automatic Summarization Algorithm for Biomedical Literature Based on Se-mantic Relation Extraction

Automatic summarization can help biomedical researchers to get a general idea of the given concept and make the research more efficient. Using semantic relation to extract summaries can cover information in more aspects on semantic level. Researchers can get the knowledge more easily. This paper extracts the important semantic relation of concepts from biomedical literatures, and uses the semantic relation as the character of measuring sentence importance to generate the summary. It focuses on five diseases, such as H1N1, rheumatism and encephalomyelitis. Summary extracted contains the causes, types and treatments of the given diseases. Experimental results show that this method can improve the summarizing performance. Compared with the general method, the summarization with semantic relations can integrate the content of multi-document on semantic level and meet the need of biomedical researchers.
