[0021] The first rule set stores keywords related to public opinion. The analysis in step two is to extract keywords from the extracted text and compare the extracted keywords with the keywords related to public opinion in the first rule set. When there are matching items, the output analysis result is abnormal; otherwise, it is normal.
