    • Multiple sets of words and phrases can be used as query terms for accessing sponsored content. Sponsored content is associated with item terms. The query terms are matched with the item terms. The result of the matching operation is a numerical score for each item of sponsored content that can be used to select sponsored content. Conditions present across the set of matched terms are detected. Such conditions can include the occurrence of a matched query term in multiple sets of query terms. This condition can be addressed by determining a number of unique matching query terms across all sets of query terms. The score given to an item of sponsored content can be adjusted if such a condition occurs. For example, the score could be adjusted according to a function of the number of unique matching query terms across all sets of query terms. If the number of matching query terms across all sets of query terms is low, such as one or two, then the function can define a penalty to be applied to the score given to the item of sponsored content. If the number of matching query terms across all sets of query terms is higher, such as three or more, then the function can define an adjustment to be applied to the score given to the item of sponsored content.
    • 可以使用多组单词和短语作为访问赞助内容的查询条件。 赞助内容与项目条款相关联。 查询条款与项目条款匹配。 匹配操作的结果是可以用于选择赞助内容的每个赞助内容的项目的数值分数。 检测到匹配项集合中存在的条件。 这样的条件可以包括在多组查询项中出现匹配的查询项。 可以通过确定所有查询项集合中的唯一匹配查询项的数量来解决此问题。 如果发生这种情况,则可以调整给予赞助内容的项目的分数。 例如,可以根据跨所有查询词组的唯一匹配查询词的数量的函数来调整分数。 如果所有查询词集合中的匹配查询词的数量较少,例如一个或两个,那么该函数可以定义应用于给予赞助内容项目的分数的惩罚。 如果所有查询项集合中的匹配查询词的数量较高,例如三个或更多个,则该函数可以定义适用于给予赞助内容项目的分数的调整。
