1 Multi-document Summarization Focusing on Extracting and Integrating Similarities and Differences among Documents

The study was to develop a method for automatic summarization of sets of related research abstracts. This summarization method focused on extracting and integrating similarities and differences among different abstracts. In the research studies which aim to look for relationships between research concepts, similarities and differences are mainly reflected through research concepts and relationships expressed in the text. Thus the summarization method extracts research concepts and relationships from each research abstract, integrates similar concepts and relationships across different abstracts, and incorporates them into new sentences to produce a summary. This paper reports the three main summarization steps – discourse parsing, concept extraction and integration, and relationship extraction and integration. Each step was evaluated by comparing the machine output against
