Table 3. Results labelled with baseline features and one of additional features for extracting unknown products and shops From Table 5, it turns out that the performances for unknown entities are improved when the method uses the baseline features and BIOES labeling scheme. It confirmed that the performance of extracting unknown entities is lower than that with the baseline features when the extraction method uses the baseline features and one of additional features other than “BIOES”. In particular, the performance of the method with "exBracket" or "correctPOS" for unknown entities is down about two or three points.
