| Experiments and Results | One should note that, in general, better performance was obtained when using character-level rather than word-level information. |
| Experiments and Results | This confirms the results already reported by other researchers that have used character-level and word-level information for AA (Houvardas and Stamatatos, 2006; |
| Experiments and Results | Also, n-gram information is more dense in documents than word-level information. |
| Introduction | Also, we empirically show that local histograms at the character-level are more helpful than local histograms at the word-level for AA. |
| Related Work | Some researchers have gone a step further and have attempted to capture sequential information by using n-grams at the word-level (Peng et al., 2004) or by discovering maximal frequent word sequences (Coyotl-Morales et al., 2006). |
