Summarizing differences in information that changes with time

Abstract

This paper describes methods for extracting and summarizing information that changes with time in a semantic coherent manner so that people can easily understand what has changed. Specifically, using CTD (Comparative Toxicogenomics Database) as an example, we describe the extraction of differences in CSV and some KG representation, difference extraction, and summarization with version information. We also refer to the application to laws and regulations.
