附图说明
图 1是本发明的一种显示相关关键词方法的步骤流程图;
图 2是本发明的一种用户操作界面的示意图;
图 3是本发明的一种显示相关关键词系统的结构框图;
图 4为图 3所示的第一实施例;
图 5为图 3所示的第二实施例。
具体实施方式
为使本发明的上述目的、 特征和优点能够更加明显易懂, 下面结合附 图和具体实施方式对本发明作进一步详细的说明。
本发明实施例根据主关键词提取相关关键词的请求次数, 获取相应的 相关关键词分组表, 从而实现相关关键词的全面轮循显示。
参照图 1 , 示出了本发明的一种显示相关关键词方法的流程图, 包括 以下步骤:
步骤 101、 接收用户输入的主关键词, 提取对应所述主关键词的相关 关键词的请求;
用户在使用搜索工具或搜索引擎时, 利用输入设备, 比如键盘、 手写 板等在搜索栏或工具栏输入主关键词后, 通过点击确定、 按回车键、 TAB 键或其它触发方式即可触发本地程序或搜索页面的脚本程序发出提取与所 述主关键词对应的相关关键词的请求。
步骤 102、 根据所述主关键词记录所述请求的次数;
优选的是, 一种记录所述次数的方法包括以下子步骤:
子步骤 A1 : 根据每个 Key创建表格, 每个表格包括两个字段: Key和
Value, 将所述 Value存储于与所述 Key对应的位置;
其中, 所述 Key为主关键词, 所述 Value为根据该主关键词发出请求 的次数;
子步骤 A2: 根据所述请求查找匹配的 Key, 获取所述表格中对应位置 的 Value, 将所述 Value加 1并记录。
可以理解的是, 通过获取所述表格中对应位置的 Value, 如果已知根据 该主关键词已经发出过 3次请求, 则根据当前请求将 Value加 1 , 得到次数 为 4; 如果已知才艮据该主关键词未发出过请求, 则才艮据当前请求将 Value加 1, 得到次数为 1。
当然, 上述记录的方法仅仅用于举例, 其它能够实现在緩存中记录次 数的方法都是可行的, 在此无法——详述而已。 例如, 本领域技术人员易 于想到, 可以根据所述主关键词创建文件, 读取到文件下的次数记录后, 然后加 1更新文件等, 对此本发明无需进行限定。
所述表格可以存储在服务器中, 优选的是, 所述表格存储在服务器端 的緩存中。 从而有利于减少系统资源的占用, 并有效提高系统的处理效率。
步骤 103、 根据所述次数从对应所述主关键词的相关关键词分组表中 获取候选相关关键词分组表;
为了使所述请求得到快速响应, 特别是在高并发的状态下, 充分节省 服务器的资源及空间, 有效提高服务器的处理效率, 优选的是, 所述对应 主关键词的相关关键词分组表存储在服务器端的緩存中。
在实际应用中, 一种可能的情况是, 由于所述主关键词及相关关键词 的应用较多 ,在服务器的数据库中已经保存了主关键词及对应相关关键词。 在这种情况下, 本实施例的一种实现方式为, 在所述数据库中提取与所述 主关键词对应的相关关键词, 再对这些相关关键词进行分组, 生成相关关 键词分组表并保存至緩存中, 以便用户在下一次针对该主关键词发出对应 的相关关键词的提取请求时, 可以直接从緩存中获取相应的相关关键词分 组表。 因此, 本发明一种优选的实施例为, 通过以下子步骤将对应主关键 词的相关关键词分组表存储在服务器端的緩存中:
子步骤 Bl、 在数据库中提取与所述主关键词对应的相关关键词; 子步骤 B2、 对所述相关关键词进行分组, 生成相关关键词分组表, 并 将所述相关关键词分组表保存至所述緩存中。
在实际应用中, 另一种可能的情况是, 数据库中并未预置主关键词及 对应的相关关键词。 在这种情况下, 本实施例的一种实现方式为, 根据所 述主关键词获取对应的相关关键词, 然后对所述相关关键词进行分组, 生 成相关关键词分组表, 并将所述相关关键词分组表保存至数据库中, 如果 从緩存中不能获取到相应的相关关键词分组表, 则到数据库中提取相应的 相关关键词分组表并保存至緩存中。 因此, 另一种优选的实施例为, 通过 以下子步骤将对应主关键词的相关关键词分组表存储在服务器端的緩存 中:
子步骤 Cl、 获取与所述主关键词对应的相关关键词;
所述相关关键词可以由本领域技术人员根据需要或经验获取, 例如, 通过多重排列组合获取与所述主关键词对应的相关关键词等 , 本发明对此不 需要进行限定。
子步骤 C2、 对所述相关关键词进行分组, 生成相关关键词分组表, 并 将所述相关关键词分组表保存至数据库中;
子步骤 C3、在数据库中提取对应所述主关键词的相关关键词分组表并 保存至所述緩存中。
当然, 上述存储相关关键词分组表的方式仅仅用于举例, 本发明并不 限于上述两种方式,本领域技术人员可以根据需要或者经验设置其它方式, 本发明对此不作限制。
在实际应用中, 一种优选的生成分组表的方法包括以下子步骤: 子步骤 D1、 在所述相关关键词中确定固定关键词和轮循关键词; 子步骤 D2、 根据主关键词预置至少一个相关关键词分组表, 并在所述 相关关键词分组表中添加所述固定关键词和轮循关键词。
例如 ,通过以下公式计算获得应当预置的相关关键词分组表 P的个数: P=((M-N-1)/L)+1 ;
其中, M为某个主关键词对应的相关关键词的总数; N为固定关键词 的数量; L为轮循关键词的数量; 在实际应用中, N和 L可以由本领域技 术人员根据需要或经验进行设置, 假设 M=50, N=10, L=10, 那么通过以 上公式计算得到应当设置的相关关键词分组表为 4组。 然后, 根据所述主 关键词预置 4个相关关键词分组表, 并在每个相关关键词分组表中添加固 定关键词和轮循关键词。
当然, 上述生成相关关键词分组表的方法仅仅用于举例, 本发明并不 限于上述方法, 其它能够生成相关关键词分组表的方式都是可行的, 在此 无法一一伴述而已。
优选的是, 本发明还可以通过以下子步骤确定固定关键词和轮循关键 词:
子步骤 El、 统计各个相关关键词与主关键词的相关度;
所述统计相关度的方法可以由本领域技术人员根据需要或经验设置, 例如,可以根据主关键词和相关关键词的同时出现概率来计算所述相关度, 也可以采用现有技术中来计算所述相关度, 本发明对此不需要进行限定。
子步骤 E2、 将所述相关度大于或等于一定阔值的相关关键词确定为固 定关键词;
子步骤 E3、 将所述相关度小于一定阔值的相关关键词确定为轮循关键 词。
在实际应用中, 所述固定关键词为在每个相关关键词分组表中固定存 在并提供给用户显示的相关关键词, 设置这种固定关键词的好处在于, 用 户不论获得哪个相关关键词分组表中的数据, 都可以获得相关度较高的推 荐项, 更符合用户的使用习惯, 用户体验更好; 例如, 对于主关键词 bike, 具有 10 个固定关键词为: electric bike, mountain bike, e bike, e bicycle, suspension bike, scooter, motorcycle, electric scooter, gas scooter, vehicle , 那 么, 这 10个固定关键词, 都会固定存在于每个相关关键词分组表中, 当用 户针对 bike发出对应的相关关键词提取请求时, 不论所述提取请求的次数 对应哪个相关关键词分组表,上述 10个固定关键词都会出现在相关关键词 分组表中提供给用户显示。
所述轮循关键词可以理解为除固定关键词以外的其它相关关键词, 对 于这部分相关关键词 , 可以按照任意规则把它们分别添加到每个相关关键 词分组表中, 优选的是, 需要保证每个轮循关键词只被添加到一个相关关 键词分组表中, 这样处理的好处在于, 可以使所有的相关关键词获得全部 展示的机会。 当用户通过对某个主关键词发出多次提取请求时, 会根据提 取请求的次数循环调用相应的相关关键词分组表, 从而使用户能够简单、 全面的获得相关关键词。 例如, 对于主关键词 bike , 具有轮循关键词: motorbike, scooter, motorcycle, electric scooter, exercise bike, vehicle, fitness, auto, mini motor等, 则可将 motorbike, scooter, motorcycle, electric scooter 添力口到第一个相关关键词分组表中 ,而将 exercise bike, vehicle, fitness, auto, mini motor 添加到第二个相关关键词分组表中, 当然, 在任一个相关关键 词分组表中添加的个数可以由本领域技术人员任意设置, 本发明对此不作 限制。
为了使所述相关关键词分组表得以轮循显示, 一种简单获取候选相关 关键词分组表的方法为: 通过对请求次数按相应的相关关键词分组表数取 模获取候选相关关键词分组表。
在这种情况下, 假设緩存中记录针对某一主关键词的请求次数为 10, 分组表数为 4, 那么, 得到的分组表为: 10 mod 4 =2, 在这种情况下, 则返 回第 2个相关关键词分组表, 也可以是, 排列在第 2位的相关关键词分组 表, 还可以是, 分组表号为 2的相关关键词分组表。 其中, 对于排列在第 2位的相关关键词分组表或分组表号为 2的相关关键词分组表, 可以作为 候选相关关键词分组表; 如果用户再次对该关键词发出请求, 则得到请求 次数为 11, 分组表数为 4, 那么, 得到的分组表为 11 mod 4 =3, 即返回分 第 3个相关关键词分组表, 也可以是, 排列在第 3位的相关关键词分组表, 还可以是, 分组表号为 3 的相关关键词分组表为候选相关关键词分组表。 对于所述次数与相关关键词分组表的对应规则可以由本领域技术人员任意 设置。 此外, 上述获取方法仅仅用于举例, 本发明并不限于上述方法, 其 它根据所述次数记录按照任意规则获取相关关键词分组表为候选相关关键 词分组表的方法都是可行的, 在此无法——详述而已。
步骤 104、 显示所述候选相关关键词分组表中的相关关键词。
所述显示可以为在当前搜索页面上显示, 也可以为在搜索结果页面上 显示, 本实施例可以在任一种显示场景或设备中显示, 本发明对此不作限 制。
为使本领域技术人员更好地理解本发明, 以下通过举例详细说明本发 明的优选实施例。
参考图 2, 为本发明的一种用户操作界面的示意图, 用户在主关键词 输入框 , product Keyword字段所对应的输入框中输入主关键词 bike , 当鼠 标移动到相关关键词输入框, More Keywords 字段所对应的输入框时, 即 可触发本地程序或者搜索页面的脚本程序发出提取对应所述主关键词 bike 的相关关键词的请求, 在这种情况下, 在服务器的緩存中会针对所述主关 键词 bike记录所述请求的次数, 假设所述次数为 3, 那么在緩存中获取到 对应所述主关键词的第 3个相关关键词分组表为候选相关关键词分组表, 在这个相关关键词分组表中保存的固定关键词为: electric bike, mountain bike, e bike, foldable bike, battery powered bike, bmx bike, electric bicycle, e bicycle, suspension bicycle, battery powered bicycle, children's bicycle; 轮循 关键词为: motorbike, motorbike, scooter, motorcycle, electric scooter, vehicle, gas scooter, auto, mini motor, 则在相关关键词显示框中显示上述固定关键 词和轮循关键词。
当用户在在主关键词输入框 , product Keyword字段所对应的输入框中 再次输入主关键词 bike, 当鼠标移动到相关关键词输入框, More Keywords 字段所对应的输入框时, 即可再次触发本地程序或者搜索页面的脚本程序 发出提取对应所述主关键词 bike的相关关键词的请求, 在这种情况下, 在 服务器的緩存中会针对所述主关键词 bike记录所述提取请求的次数为 4, 相应地, 在緩存中获取到对应所述主关键词的第 4个相关关键词分组表为 候选相关关键词分组表, 在这个相关关键词分组表中保存的固定关键词与 上述固定关键词相同; 轮循关键词与上述轮循关键词不同。 通过再次触发 本地程序或者搜索页面的脚本程序发出提出该主关键词 bike的相关关键词 请求, 还可以继续按照上述规律在相应的相关关键词显示框中显示其它的 相关关键词分组表, 从而使用户能够简单、 全面的获得相关关键词。
