Query-Variant Advertisement Text Generation with Association Knowledge
Table 2: Automatic evaluation results. Original means the human written advertisement retrieved by the advertising system. We also show the change of Recall(q) and Recall(q+k) compared to the Original ads in the parentheses. Train and Test columns show the input settings during the training and test phases. k denotes Item Keywords ,q denotes User Query.
['Model', 'BLEU', 'Recall(k)', 'Recall(q)', 'Recall(q+k)', 'Dist1', 'Dist2', 'Train', 'Test']
Result: It should be noted that the recall(q) of the original advertisement is significantly lower than recall(k) showing that the coverage of query words is not satisfactory. The general purposed advertisement can not meet the needs of different queries. This phenomenon testifies the necessity of our proposed task, which aims to generate query-variant advertisements.
