该步骤中，可以根据匹配结果为所述当前用户筛选出排序在前的设定数目个待推荐背景。
在步骤104中，将所述筛选出的待推荐背景推送给当前用户的移动终端以供更换。
需说明的是，上述各步骤一般由服务器执行，在移动终端的数据能力满足处理要求时也可以由移动终端执行。
由该实施例可见，本公开通过获取当前用户的用户偏好标签与各个候选背景的背景标签，根据所述当前用户的用户偏好标签与所述各个候选背景的背景标签对所述当前用户与所述各个候选背景进行匹配，就可以得到匹配结果，再根据匹配结果为所述当前用户筛选出待推荐背景，然后将筛选出的待推荐背景推送给当前用户的移动终端以供更换，这样就可以实现按照用户偏好进行显示背景的主动更换，为用户提供方便，满足用户的需求。
图2是本公开根据一示例性实施例示出的另一种用于更换显示背景的方法流程图。
该方法包括以下步骤：
在步骤201中，获取当前用户的日历或个人信息，选取与所述日历或个人信息对应题材的背景，将选取的背景确定为所述候选背景。
该步骤中，可以根据日历或个人信息选取对应题材的背景。例如根据国庆时间，选取国庆题材的背景，根据个人星座，选取星座题材的背景等。
在步骤202中，获取当前用户的用户偏好标签与各个候选背景的背景标签。
在步骤203中，根据所述当前用户的用户偏好标签与所述各个候选背景的背景标签对所述当前用户与所述各个候选背景进行匹配。
该步骤可以参见步骤102的描述，此处不再赘述。
在步骤204中，根据匹配结果为所述当前用户筛选出待推荐背景。
该步骤中，可以根据匹配结果为所述当前用户筛选出排序在前的设定数目个待推荐背景。其中设定数目并不限定，可根据需要取值，例如1、2或3等。
在步骤205中，将所述筛选出的待推荐背景推送给当前用户的移动终端以供更换。
需说明的是，上述各步骤之后，当所述当前用户的移动终端接收所述待推荐背景后，可以将移动终端的桌面和/或锁屏界面更换为所述待推荐背景。
需说明的是，上述各步骤一般由服务器执行，在移动终端的数据能力满足处理要求时也可以由移动终端执行。
由该实施例可见，本公开可以根据日历或个人信息，选取与所述日历或个人信息对应题材的背景作为候选背景，再获取当前用户的用户偏好标签与各个候选背景的背景标签，根据所述当前用户的用户偏好标签与所述各个候选背景的背景标签对所述当前用户与所述各个候选背景进行匹配并筛选出待推荐背景推送给当前用户的移动终端以供更换，因此可以实现根据日历或个人信息并按照用户偏好主动更换显示背景，为用户提供方便，满足用户的需求。
图3是本公开根据一示例性实施例示出的另一种用于更换显示背景的方法流程图。
该方法以应用于服务器举例说明但不局限于此，当移动终端的数据处理能力强的时候，也可以根据需要应用于移动终端。
本公开的服务器以背景资源服务器举例说明，背景资源服务器提供各种背景资源并根据设定条件筛选出匹配背景推送给移动终端，移动终端可以利用其桌面背景管理程序获取背景资源服务器推送的背景，该获取包括主动从背景资源服务器下载或接收来自背景资源服务器的发送。移动终端可以在每天固定时间内进行下载。移动终端获取到背景资源服务器推送的背景后，更换背景或到达设定条件后再更换背景。
本公开的服务器，可以管理移动终端上传的用户信息及其偏好信息，存储和管理各种背景图片，提供后台程序供上传和管理背景图片，更主要地可以进行用户偏好和候选背景的匹配，从而根据匹配结果为用户的移动终端推送最适合用户的背景图片。本公开的移动终端，可以安装客户端，该客户端可以负责用户帐号的注册、登录和修改，收集用户的偏好信息和反馈给服务器，定时向服务器查询和下载背景，并传输给桌面背景管理程序进行背景更换。
以下详细描述图3所示方法，该方法包括以下步骤：
在步骤301中，选取不同题材的背景作为候选背景。
该步骤中服务器选取分类的不同题材的背景。背景的题材可以根据日历或个人信息确定，因此服务器可以根据日历或个人信息，选取与所述日历或个人信息对应题材的背景确定为候选背景。日历信息例如是节日、假日、节气等信息，个人信息例如是个人的生日、星座、结婚纪念日等信息。例如，在传统节日春节，选取具有浓厚节日气氛的桌面背景；在法定假日，如国庆节，选取国庆相关的背景；在个人生日时，选取有蛋糕、花束等内容的桌面背景。在一些年轻人中，比较喜欢星座与运势，那么可以根据用户的星座选取能够暗示运势的桌面背景。
在步骤302中，获取各个候选背景的背景标签。
因为用户的审美情趣都不一样，有的喜欢颜色鲜艳的，有的则喜欢朦胧清淡的等等，因此背景会设置有不同的背景标签。该背景标签可以由背景设计者、背景上传者或背景使用者设置，也可以由服务器为背景进行设置。对于同一题材，可以设计出不同风格的背景提供给用户使用，风格与背景的关联，通过背景标签来表示。
背景标签可以有各种不同设置，例如背景标签为：清新、朦胧；或者是火热、摇滚等等。一个背景可以有多个背景标签。
在步骤303中，获取当前用户的用户偏好标签。
用户对背景的偏好，通过用户偏好标签表示。用户偏好标签，可以由一组标签组成，即可以有多个标签表示偏好，其中每个标签可以具有不同的权重。
例如用户喜欢清新、朦胧、抽象的背景，那么用户的用户偏好标签为：清新、朦胧、抽象。
本公开可以通过不同方式确定用户对背景的喜好程度，包括：
1)根据服务器的评价系统的记录确定：评价系统记录用户对当前使用的背景进行的评价：喜欢、不喜欢、一般等，例如用户对背景标签为清新的背景评价为喜欢，对背景标 签为鲜艳的背景评价为一般，那么用户的用户偏好标签为：清新、鲜艳。
2)根据服务器记录的用户的主动选择确定：服务器记录用户主动选择的一些背景，被选择的背景就是用户喜欢的背景，反之一般是不喜欢的背景。例如用户主动选择背景标签为清新的背景，那么可确定用户的用户偏好标签为：清新。
3)根据服务器记录的用户的偏好自述确定：服务器记录用户编辑的自己的用户偏好标签，如清新、朦胧等，或接收用户直接向服务器反馈的用户偏好标签。
对于用户偏好标签，其中每个标签可以具有不同的权重，也称为用户偏好标签权重。
用户在第一次使用背景时，可以让用户为自己选择标签作为用户偏好标签，或者添加自己的标签作为用户偏好标签，此时每个标签的权重可以是一样的，例如用户偏好标签中包括清新、朦胧等，那么标签清新和朦胧的权重是一样的。
在后续的日常使用中，如果用户更喜欢某个背景，那么与这个背景的背景标签对应的用户偏好标签就会增加权重；相反，如果用户不喜欢某个背景，那么与这个背景的背景标签对应的用户偏好标签就会减小权重。例如，后续用户更多选取背景标签为清新的背景，那么用户偏好标签清新就会增加权重。如果用户后续有将背景标签为朦胧的背景选为不喜欢或长时间不选取朦胧的背景，那么用户偏好标签朦胧就会减小权重。
本公开可以根据权重修正算法确定权重。权重可以考虑时间和频度两个因素。设定时间内，用户对用户偏好标签的某个标签的喜欢次数越多，权重增加的就越多，反之亦然。但是当权重增加或减少到一定程度后，增加或减小的速度就会下降。
本公开的权重修正处理包括:
权重值由两部分组成，即：W＝B+F
W：表示权重值。
B:表示基础权重。基础权重可以由用户确定，可以根据用户的偏好描述方式确定。
F：表示行为权重。行为权重可以根据用户的评价确定。
一般基础权重是比较固定的，一旦用户选择了某个标签，就可以确定一个固定值。一般每个标签的基础权重可以是一样的。例如上述用户偏好标签的标签清新和朦胧的基础权重可以一样，如都是固定的2分。
行为权重，可以由喜好评分确定，包括根据设定背景使用时间内的用户喜好评分确定，因此一般不是固定的，可以动态变化。例如，喜好评分由喜欢、一般、不喜欢分成3挡，评分值从高到低，例如分别对应3、2、1分。
行为权重F的计算方式如下：F＝R(T,S)
其中，S表示评分总数(固定时间内，每次评分的总和)，T表示时间，R表示计算函数。
本公开根据时间可以分为3段：最近一周内、最近一月内、从用户注册起到当前。需说明的是，此处只是对时间分段举例说明，还可以根据需求进行其他方式的分段。
综合3个时间段，可以得出：
F＝R1(T1，S1)+R2(T2，S2)+R3(T3，S3)
R1(T1，S1)表示最近一周内(T1)评分总数(S1)的R1计算函数。
R2(T2，S2)表示最近一月内(T2)评分总数(S2)的R2计算函数。
R3(T3，S3)表示从用户注册起到当前(T3)评分总数(S3)的R3计算函数。
如果是新注册用户，或者刚注册不仅的用户，时间记录太短，如小于1分钟，T可以直接取值为0。
上述R1、R2、R3分别是三个不同的函数，计算得到的值R1>R2>R3，这样可以让用户近期的行为起到更加大的作用。
在R1、R2、R3函数选择上，本公开可以使用对数函数，或者类似的函数，以满足以下目的：随着评分总数S的增加或减小，返回值R增加或减小的速度小于S增加或减小的速度，当S增加或减小到一定程度后，返回值R就会趋近一个固定值，不再增加或减小。因此本公开使用对数函数R可以满足上述目的要求。
需说明的是，上述步骤302与303没有必然的顺序关系。
在步骤304中，根据当前用户的用户偏好标签与各个候选背景的背景标签对当前用户与所述各个候选背景进行匹配。
本公开的用户偏好与背景的匹配，通过用户偏好标签与背景标签的关联度匹配完成。
该步骤获取当前用户的每个用户偏好标签与当前候选背景的每个背景标签的关联度，将当前用户的每个用户偏好标签与当前候选背景的每个背景标签的关联度相加，根据当前用户的用户偏好标签总数对所述相加的结果进行平均，得到所述当前用户与所述当前候选背景的关联度，将当前用户与各个候选背景的关联度进行排序，根据排序结果得到所述当前用户与所述各个候选背景的匹配结果。
以下详细描述该步骤处理过程：
本公开获取当前用户的每个用户偏好标签与当前候选背景的每个背景标签的关联度后，首先对用户偏好标签和背景标签进行两两关联度匹配，然后将用户偏好标签的权重作为因子，将当前用户的每个用户偏好标签与当前候选背景的每个背景标签的关联度相加，也就是将关联度进行加权求和，得出求和总分；再将求和总分除以用户偏好标签数量得到最终得分，就得到当前用户与当前候选背景的关联度，将当前用户与各个候选背景的关联度进行排序，最终得分最高的关联度为匹配度最高，得分次高者为匹配度次高，依次类推。
假设，标签用小写字母a、b、c、d...表示；标签的关联度，由计算函数R来计算，计算函数R可以是概率函数，例如百分比函数或类似函数等。R(a，b)表示标签a，b之间的关联度；标签的权重，由函数W来计算，W(a)表示标签a在用户中的偏好权重。
假设，当前用户的用户偏好标签是a，b；某个候选背景的背景标签是c，d，那么根据以下方式得到的总分M为：
M＝(R(a，c)+R(a，d))*W(a)+(R(b，c)+R(b，d))*W(b)
最后的得分F＝M/2，即当前用户与当前候选背景的关联度为F＝M/2。
因为用户偏好标签有两个标签分别为a，b，因此最后是取得平均分将M除以2，如果用户偏好标签数量是有N个标签就除以N。
如果用户偏好标签是a，b，e，计算以下：
M＝(R(a，c)+R(a，d))*W(a)+(R(b，c)+R(b，d))*W(b)+(R(e，c)+R(e，d))*W(e)
最后的得分F＝M/3
如果背景标签是c、d、e，计算以下：
M＝(R(a，c)+R(a，d)+R(a，e))*W(a)+(R(b，c)+R(b，d)+R(b，e))*W(b)
最后的得分F＝M/2
得到当前用户与当前候选背景的关联度后，就将当前用户与各个候选背景的关联度进行排序，最终得分最高的关联度为匹配度最高。
需说明的是，上述获取的关联度，可以从已计算确定的关联度表中直接查找并使用。
上述的用户偏好标签与背景标签的关联度，可以根据所述用户偏好标签与所述背景标签同时出现在同一个用户的用户偏好标签集合中的次数、或同时出现在同一个背景的背景标签集合中的次数确定。
例如关联度R(a，c)，是根据标签a,c在用户偏好标签集合或者背景标签集合中同时出现的次数占总用户数与总背景数之和的比例来确定的。R(a，c)的值是一个概率统计的结果。如果两个标签同时出现在用户偏好标签集合或者背景标签集合中的比例高，那么说明这两个标签的关联度高；反之，两个标签的关联度就低。例如，一般标签“清新”与“朦胧”的关联度会高一些，而标签“鲜艳”和“朦胧”的关联度就会低一些。
本公开的关联度的确定过程包括:
例如，在服务器上，存在N个用户和M个背景。其中，每个用户都包含一组用户偏好标签，每个背景也包含一组背景标签。用户偏好标签和背景标签包含的标签数，必须>＝1。
确定关联度的过程如下：
1)定义一个大映射表X＝{}，X表中，可以每两个标签为一组，记录这两个标签在在用户偏好标签集合或者背景标签集合中同时出现的次数。
2)循环获取每个用户或者背景的标签，假设这个标签列表是{a,b,c,d,e,d.....}
2.1)取出所有的两两组合：{a,b},{a,c},{a,d},....{b,c},{b,d},....{c,d},{c,e}........
2.2)将这些标签组，存入到X表中，如果该标签组已经存在，则计数加1；
3)获取总用户数和总背景数(N+M)，X表中，每个标签组的次数占总用户数与总背景数之和的比值，就是它们的关联度。
还需说明的是，对于只有一个标签的用户或者背景，上述处理过程中计入分母，不计入分子。因为单独标签的情况也代表了一种偏好组合，对标签的关联度也产生影响。上述关联度的值在一次计算后，可以存储到一个关联度表内，使用时，根据标签组合情况从关 联度表中直接获取，不需要再计算。另外，可以存储X表，当有新背景或新用户增加时，可以重新更新标签组合的计数，并更新关联度表；或者，如果用户的用户偏好标签发生变化，那么将变化前的标签组合在X表内减1，将变化后的标签组合在X表内加1，从而实现对X表的更新，然后再更新关联度表。对于背景的标签，则确定后一般不修改。
还需说明的是，本公开是将用户偏好标签与背景标签进行两两匹配，不是在户偏好标签之间或者背景标签之间进行两两匹配。
在步骤305中，根据匹配结果为当前用户筛选出待推荐背景。
该步骤中，根据前述得到的最终得分F，确定得分最高者为匹配度最高，得分次高者为匹配度次高，依次类推，从而可以筛选出排序在前的待推荐背景，可以只筛选出得分最高的待推荐背景，也可以同时筛选出得分最高和次高的待推荐背景。
在步骤306中，将筛选出的待推荐背景推送给当前用户的移动终端以供更换。
该步骤中，将筛选出的待推荐背景推送给当前用户的移动终端进行更换。
移动终端接收待推荐背景后，可以通过桌面背景管理程序将移动终端的桌面和/或锁屏界面更换为所述待推荐背景。
假设目前是国庆节，步骤301选取的是国庆题材的背景，那么推送的就可以是国庆节题材中筛选出的待推荐背景。
如果步骤301选取的是根据个人信息例如用户星座信息题材的背景，那么推送的就是星座题材中筛选出的待推荐背景。
需说明的是，如果步骤301中不是按不同分类题材选取背景，那么将在所有背景中进行筛选匹配。
需说明的是，本公开还可以每到达设定周期例如每隔7天，将筛选的所述待推荐背景推送给移动终端进行更换。
本公开的实施例的方案，可以根据用户偏好主动推送筛选出的待推荐背景，可以免去用户查找、选择不同背景的过程，即节省大量查找时间，也让用户省心，而且对于用户而言几乎不需要学习就可以更换不同的背景，特别方便对移动终端使用不熟练的用户，另外还可以根据日历和个人信息进行推送，例如国庆时推送国庆题材中用户喜好风格的背景，从而增加用户使用移动终端的乐趣，避免一直使用过于单调的背景。
