== 輸入文字範例1 == <pre> 我喜歡 pokemon。 我不喜歡 pokemon。 我樂愛 pokemon。 我不樂愛 pokemon。 </pre> 三種類型情緒 # 正面情緒 (positive sentiment) #* 方式: 搜尋包含「喜歡」、「樂愛」但是前面不緊接「不」字 #* 搜尋: {{kbd | key =<nowiki>[^不](喜歡|樂愛)</nowiki>}} # 負面情緒 (negative sentiment) #* 方式: 搜尋包含「不喜歡」、「不樂愛」 #* 搜尋: {{kbd | key =<nowiki>[不](喜歡|樂愛)</nowiki>}} # 中性情緒 (neural sentiment) #* 方式: 搜尋不包含「喜歡」、「樂愛」 #* 搜尋: {{kbd | key =<nowiki>^((?!(喜歡|樂愛)).)*$</nowiki>}} 但是這樣的搜尋方式,沒有處理到雙重否定 (double negative,負負得正) 比較複雜文法的句子。
