Description

一种评估媒体文件的方法及装置
本申请要求于2014年08月15日提交中国专利局、申请号为201410403351.7、发明名称为“一种评估媒体文件的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及信息处理技术领域，尤其涉及一种评估媒体文件的方法及装置。
背景技术
随着互联网的发展，越来越多的媒体文件出现在互联网上，如：音乐、视频、电子书等。为了对大量的媒体文件进行整合，互联网上有不同的网站，如音乐网站、视频网站、电子书网站等。其中，音乐网站集合了大量的音乐，而视频网站集合了大量的视频，电子书网站集合了大量的电子书。当用户想要播放不同类型的媒体文件时，用户可以通过互联网连接不同的网站，然后播放媒体文件。
由于互联网上存在大量的媒体文件，所以，用户无法快速从大量的媒体文件中选择并播放哪些媒体文件。为此，网站会向用户提供媒体文件推荐，统计众多用户对大量的媒体文件的评估结果，将评估结果是优秀的媒体文件推荐给用户。以音乐网站为例，音乐网站统计音乐在一段时间内被众多用户播放的次数，根据播放次数形成音乐播放次数排行榜，然后将音乐播放次数排行榜推荐给用户。或者音乐网站统计众多用户对音乐的打分，形成音乐分数排行榜，然后将音乐分数排行榜推荐给用户。
但是，无论是音乐播放次数排行榜还是歌曲分数排行榜，都不能对音乐进行准确地评估。因为音乐播放次数排行榜是根据播放次数形成，而用户只需点击播放即可多次播放自己喜欢的音乐，所以会造成播放次数存在 很大程度的用户主观性。而音乐分数排行榜是由用户对音乐的打分形成的，即使用户未听过音乐，也可以随意对音乐打高分或者打低分，所以打分也存在很大程度的用户主观性。
因此，现有技术中对媒体文件进行评估的方法存在很大的程度的用户主观性，不能对媒体文件的进行准确地评估。
发明内容
本发明提供一种评估媒体文件的方法及电子设备，解决了现有技术中对媒体文件进行评估的方法存在很大的程度的用户主观性，不能对媒体文件的进行准确地评估的技术问题。
本发明第一方面提供了一种评估媒体文件的方法，所述方法包括：
在媒体文件被播放的过程中，获得所述媒体文件被播放的至少一个参数；
根据所述至少一个参数，评估所述媒体文件，获得评估结果。
本发明中媒体文件被播放的至少一个参数是在媒体文件被播放的过程中获得的，而媒体文件被播放需要花费一定的时间，所以媒体文件被播放的至少一个参数减少了用户主观性，并且本发明结合在媒体文件被播放过程中获得的一个参数或多个参数，对媒体文件进行评估，一方面，提高了评估媒体文件的准确度，另一方面，通过获得不同播放终端的用户播放媒体文件的一个参数或多个参数，可以进行好友推荐，播放终端的用户在获得评估结果的同时，还可以获得好友推荐信息，提高了用户体验。
结合第一方面，在第一方面的第一种可能的实现方式中，所述获得所述媒体文件被播放的至少一个参数，包括：

由于第二完整播放率表征了在媒体文件被首次播放的过程中，媒体文件是否被完整播放，如果第二完整播放率大，则说明媒体文件对众多用户 来说，具有很大的吸引力，媒体文件被用户第一次播放，就能够吸引用户完整播放该媒体文件。所以通过第二完整播放率的大小，用户能够获知媒体文件在被首次播放的过程中，媒体文件对用户的吸引力大小。
结合第一方面，在第一方面的第六种可能的实现方式中，所述获得所述媒体文件被播放的至少一个参数，包括：
获得所述媒体文件的被停止播放率；所述获得所述媒体文件的被停止播放率，具体包括：获得所述媒体文件的被播放次数；获得所述媒体文件被停止播放的时刻；根据所述媒体文件被停止播放的时刻，确定所述被停止播放时刻出现的次数；获得所述媒体文件的被停止播放率，所述被停止播放率为所述被停止播放时刻出现的次数除以所述被播放次数。
利用确定出的被停止播放率，即停止播放时刻出现的次数占媒体文件的被播放次数的比值，对媒体文件进行评估，当该比值大于用户或者播放模块设定的阈值，则说明则该媒体文件的包含被停止播放时刻的片段不受用户欢迎，需要修改该片段，可以将修改信息发送给媒体文件的作者，媒体文件的作者可以对该片段进行修改。
结合第一方面，在第一方面的第七种可能的实现方式中，所述获得所述媒体文件被播放的至少一个参数，包括：
获得所述媒体文件的被播放率；所述获得所述媒体文件的被播放率，具体包括：获得所述媒体文件的被播放次数；获取用户的体征参数；确定所述用户的体征参数与所述媒体文件的匹配度；当所述匹配度大于预设阈值时，确定所述用户的体征参数对应的所述媒体文件的被播放时刻；确定所述被播放时刻出现的次数；获得所述媒体文件的被播放率，所述被播放率为所述被播放时刻出现的次数除以所述被播放次数。
利用确定出的被播放率，即被播放时刻出现的次数占媒体文件的被播放次数的比值，对媒体文件进行评估，当比值大于用户或者播放模块设定的阈值，则说明用户随媒体文件的播放体征参数也发生改变，说明该媒体 文件的包含被播放时刻的片段受用户欢迎。
结合第一方面或第一方面的第二种可能的实现方式至第一方面的第七种可能的实现方式中的任意一种，在第一方面的第八种可能的实现方式中，所述根据所述至少一个参数，评估所述媒体文件，获得评估结果，具体为：
根据所述至少一个参数的大小，对所述媒体文件进行排序，所述排序结果为所述评估结果。
结合第一方面或第一方面的第二种可能的实现方式至第一方面的第八种可能的实现方式中的任意一种，在第一方面的第九种可能的实现方式中，所述获得所述媒体文件被播放的至少一个参数，包括：

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本 发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供一种评估媒体文件的方法及电子设备，解决了现有技术中对媒体文件进行评估的方法存在很大的程度的用户主观性，不能对媒体文件的进行准确地评估的技术问题，实现了减少评估媒体文件的用户主观性，提高评估媒体文件的准确度。
本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图对本发明实施方式进行详细说明。
请参考图1，图1为本发明实施例中一种评估媒体文件的方法流程图。本发明实施例提供了一种评估媒体文件的方法，包括：
步骤11：在媒体文件被播放的过程中，获得所述媒体文件被播放的至少一个参数；
步骤12：根据所述至少一个参数，评估所述媒体文件，获得评估结果。
本发明实施例中，媒体文件可以为一个，也可以为多个，如两个、三个、四个等，且媒体文件可以为音乐、视频或者电子书等。
本发明实施例提供评估媒体文件的方法可以由服务器执行，也可以由播放终端执行。
其中，服务器是向播放终端提供媒体文件的电子设备。服务器是互联网上的网站的一个组成部分，当用户通过互联网访问网站时，用户可以从服务器上下载媒体文件或者在线播放媒体文件。在物理实现上，能够为其他电子设备提供媒体文件的计算机都可以作为服务器。如高性能计算机， 即相比普通计算机具有更高稳定性、安全性，且中央处理器、芯片组、内存、磁盘系统、等硬件的性能相比普通计算机更好的计算机。
播放终端是用户播放媒体文件所用的电子设备。用户可以从服务器上下载媒体文件到该电子设备中，然后利用该电子设备播放已下载的媒体文件。音乐播放器、手机、个人计算机、平板电脑、笔记本电脑等能够播放媒体文件的电子设备都可以作为播放终端。
需要说明的是，服务器是一个相对的概念，凡是能够为其他电子设备提供媒体文件的电子设备都可以作为服务器，也就是说，能够为其他电子设备提供媒体文件的播放终端也可以作为服务器。例如：手机A从手机B中下载媒体文件，则手机A可以作为服务器。所以，音乐播放器、手机、个人计算机、平板电脑、笔记本电脑等能够播放媒体文件的电子设备也可以作为本发明实施例中的服务器。
首先介绍服务器执行本发明实施例提供的评估媒体文件的方法的详细过程。
本发明实施例中，服务器执行步骤11的触发条件是：服务器获得媒体文件的开始标识及媒体文件名称。其中，开始标识为媒体文件具有的参数，例如：音乐、视频的开始时刻对应的数据帧，电子书的第一页对应的数据帧等。
具体来讲，服务器获得开始标识有如下两种获得方式。第一种获得方式为：当用户在线播放媒体文件时，通过服务器的播放模块可获得正在播放的媒体文件的开始标识；第二种获得方式为：当用户利用播放终端播放媒体文件时，服务器的播放模块接收播放终端的播放模块发送的正在播放的媒体文件的开始标识。
在服务器获得媒体文件的开始标识及媒体文件名称之后，服务器就执行步骤11及步骤12。其中，步骤11有多种实现方式，相应的，步骤12也有多种实现方式。所以下面将以多个实施例说明本发明提供的评估媒体文 件的方法。
实施例一
请参考图2A-图2D，图2A-图2D为本发明实施例一中一种评估媒体文件的方法流程图。其中，21、22、23、24均为图1中步骤11具体有四种实现方式，步骤25为图1中步骤12的具体实现方式。具体如下：
第一种实现方式21：获得所述媒体文件的被完整播放次数；
第二种实现方式22：获得所述媒体文件被完整播放的第一完整播放率；
第三种实现方式23：获得所述媒体文件被播放的平均播放率；
第四种实现方式24：获得所述媒体文件被完整播放的第二完整播放率；
步骤25：根据所述至少一个参数的大小，对所述媒体文件进行排序，所述排序结果为所述评估结果。
下面首先对第一种实现方式21做详细说明。
本发明实施例一中，被完整播放可以由用户或者播放模块设定。用户或者播放模块可以设定被完整播放为将媒体文件从头至尾地播放完毕，或者设定被完整播放为仅播放媒体文件的一部分。
本发明实施例一中，在服务器获得开始标识及媒体文件名称后，就可以执行步骤21。服务器可以通过以下两种方式来判断媒体文件是否被完整播放。
第一种方式：通过是否获得正在播放的媒体文件的结尾标识来判断。
本发明实施例一中，结尾标识的设定随被完整播放的含义的不同而变化。当被完整播放的含义为将媒体文件从头至尾地播放完毕时，用户或者播放模块可以设定结尾标识为媒体文件具有的参数，例如：音乐、视频的结尾时刻对应的数据帧，电子书的最后一页对应的数据帧。当被完整播放的含义为仅播放媒体文件的一部分时，用户或者播放模块可以设定结尾标识为媒体文件的某一数据帧，例如：音乐、视频的某一时刻对应的数据帧，电子书的某一页对应的数据帧。
与获得开始标识类似，服务器获得结尾标识有如下两种获得方式。第一种获得方式为：当用户在线播放媒体文件时，通过服务器的播放模块可获得正在播放的媒体文件的结尾标识；第二种获得方式为：当用户利用播放终端播放媒体文件时，服务器的播放模块接收播放终端的播放模块发送的正在播放的媒体文件的结束标识。
在媒体文件的一次被播放的过程中，如果服务器获得该媒体文件的结尾标识，则确定该次播放为完整播放，如果服务器未获得该媒体文件的结尾标识，则确定该次播放不为完整播放。
第二种方式：通过将正在播放的媒体文件的被播放时间与预定播放时间的比较结果来判断。
本发明实施例一中，预定播放时间的设定随被完整播放的含义的不同而变化。当被完整播放的含义为将媒体文件从头至尾地播放完毕时，用户或者播放模块可以设定预定播放时间为将媒体文件从头至尾播放完毕所需要的时间。当被完整播放的含义为仅播放媒体文件的一部分时，用户或者播放模块可以设定预定播放时间为：将媒体文件从头至尾播放完毕所需要的时间的预定比例，如80％，90％。例如：将媒体文件从头至尾播放完毕所需要的时间为6分钟，则预定播放时间可以设置为6分钟，5分钟，4分钟等。
本发明实施例一中被播放时间随媒体文件的不同具有不同的含义。当媒体文件为音乐、视频等时，被播放时间即为音频、视频等被观看的持续时间；当媒体文件为电子书、演示文稿等时，被播放时间即为电子书、演示文稿等在显示模块上处于显示状态的持续时间。
本发明实施例一中，被播放时间可以是从播放模块获得了正在播放的媒体文件的开始标识的时刻开始计时，即媒体文件被播放就开始计时。被播放时间也可以是从播放模块开始播放媒体文件后的某一时刻开始计时，即媒体文件被播放一段时间后才开始计时。本发明实施例并不做限定。
如果在媒体文件被播放的过程中，媒体文件被快进或快退，就将快进时刻或快退时刻减去开始计时时刻得到的时间差作为媒体文件的被播放时间；当媒体文件被快进或快退之后继续播放，就继续计时，即在快进时刻或快退时刻记录的被播放时间的基础上继续计时。
当媒体文件被快退一次或者多次时，被播放时间会大于将媒体文件从头至尾播放完毕所需要的时间。如将一个媒体文件从头至尾播放完毕所需要的时间为5分钟，在该媒体文件被播放到2分钟时，快退到媒体文件的1分钟的时刻继续播放至媒体文件的结尾，则被播放时间为[2+(5-1)]＝6分钟，即大于5分钟。
服务器获得被播放时间有如下两种获得方式。第一种获得方式为：当用户在线播放媒体文件时，通过服务器的计时模块可获得正在播放的媒体文件的被播放时间；第二种获得方式为：当用户利用播放终端播放媒体文件时，服务器的播放模块接收播放终端的计时模块发送的正在播放的媒体文件的被播放时间。
在媒体文件的一次被播放的过程中，如果被播放时间大于等于预定播放时间，则确定该次播放为完整播放，如果被播放时间小于预定播放时间，则确定该次播放不为完整播放。
当媒体文件被播放了N次时，服务器可以依次取n从1至N，检测媒体文件第n次被播放的过程中是否获得了媒体文件的结尾标识，如果服务器获得了M个该媒体文件的结尾标识，则确定媒体文件的被完整播放次数为M次。或者服务器可以依次取n从1至N，获得媒体文件第n次被播放的过程中的第n次被播放时间，并判断第n次被播放时间是否等于预设被播放时间，如果服务器获得的N个被播放时间中有M个被播放时间等于预定播放时间，则确定媒体文件的被完整播放次数为M次，其中，N为大于等于1的任一整数，n及M为大于等于1且小于等于N的整数。
接下来，对第二种实现方式22做详细说明。
本发明实施例一中，第二种实现方式22具体为：获得所述媒体文件的被播放次数；获得所述媒体文件被完整播放的第一完整播放率，所述第一完整播放率为所述被完整播放次数除以所述被播放次数。
本发明实施例一中，服务器可以通过是否获得正在播放的媒体文件的开始标识来判断媒体文件是否被播放。
由于前文已经详细说明了服务器获得开始标识的两种获得方式，所以，在此就不再赘述。在媒体文件的一次被播放的过程中，如果服务器获得该媒体文件的开始标识，则确定该媒体文件被播放，如果服务器未获得该媒体文件的开始标识，则确定该媒体文件未被播放。
当服务器获得了N个该媒体文件的开始标识，则确定媒体文件的被播放次数为N次。
由于在第一种实现方式21中获得了媒体文件的被完整播放次数为M次，所以将被完整播放次数M除以被播放次数N，即得到了媒体文件被完整播放的第一完整播放率。
然后，对第三种实现方式23做详细说明。
第三种实现方式23有且不限于以下两种具体实施方式：
第一种具体实施方式：在所述媒体文件被播放的过程中，获得所述媒体文件的被播放时间；获得所述被播放时间占预定播放时间的比值；对所述比值进行平均，获得平均值，将所述平均值确定为平均播放率。
第二种具体实施方式：在所述媒体文件被播放的过程中，获得所述媒体文件的被播放时间；在获得所述媒体文件的被播放时间之后，还获得播放所述媒体文件的至少一个播放终端的播放信息；根据所述至少一个播放终端的播放信息，确定所述至少一个播放终端的平均播放率；对所述至少一个播放终端的平均播放率进行平均，确定所述媒体文件被播放的平均播放率。
首先对第一种具体实施方式做详细说明。
由于前文已经详细说明了服务器获得被播放时间的两种获得方式及预定播放时间，所以，在此就不再赘述。服务器计算被播放时间占预定播放时间的比值，以及计算比值的平均值，平均值即为平均播放率。
当媒体文件被播放了N次时，服务器可以依次取n从1至N，获得媒体文件第n次被播放的过程中的第n次被播放时间，并计算第n次被播放时间占预定播放时间的第n个比值，共获得N个比值，然后计算N个比值的平均值，获得平均播放率。
例如：预定播放时间为10分钟，一个媒体文件被播放了5次，第1次播放的被播放时间为5分钟，第2次播放的被播放时间为6分钟，第3次播放的被播放时间为7分钟，第4次播放的被播放时间为4分钟，第5次播放的被播放时间为9分钟，则服务器计算得到的比值分别为：50％、60％、70％、40％及90％，然后计算5个比值的平均值，得到的平均值为：
Figure PCTCN2015074851-appb-000001
该媒体文件的平均播放率就为62％。
接下来对第二种具体实施方式做详细说明。
具体来讲，由于一个媒体文件会被不同的播放终端播放，所以服务器在接收播放终端的计时模块发送的正在播放的媒体文件的被播放时间之后，还可以获得播放所述媒体文件的播放终端的播放信息，即被播放时间是由哪个播放终端发送的。然后服务器分别计算多个播放终端的平均播放率，再计算多个播放终端的平均播放率的平均值，将计算出的平均值确定为该媒体文件被播放的平均播放率。
例如：预定播放时间为10分钟，一个媒体文件被播放终端A播放了3次，第1次播放的被播放时间为5分钟，第2次播放的被播放时间为6分钟，第3次播放的被播放时间为7分钟，则服务器计算出播放终端A的平均播放率为：
Figure PCTCN2015074851-appb-000002
此外，该媒体文件被播放终端B播放了2次，第1次播放的被播放时间为4分钟，第2次播放的被播放时间为9 分钟，则服务器计算出播放终端B的平均播放率就为65％。然后计算播放终端A的平均播放率60％与播放终端B的平均播放率65％的平均值，确定该媒体文件被播放的平均播放率为62.5％。
最后，对第四种实现方式24做详细说明。
本发明实施例一中，第四种实现方式24具体为：获得所述媒体文件的被首次播放次数；获得所述被首次播放次数中的被首次完整播放次数；获得所述媒体文件的被完整播放的第二完整播放率，所述第二完整播放率为所述被首次完整播放次数除以所述被首次播放次数。
服务器确定媒体文件的一次被播放为被首次播放的方法为：首先，服务器接收播放终端的播放模块发送的已被播放的媒体文件的播放记录，然后，当用户利用播放终端播放一个媒体文件时，服务器还可以接收播放终端的播放模块发送的正在播放的媒体文件的开始标识及媒体文件名称，最后服务器判断该媒体文件名称是否在播放记录中首次出现，如果判断结果为是，则确定该次播放为被首次播放。
如果服务器获得了P个播放终端的P个播放记录，服务器可以依次取p从1至P，获得媒体文件被第p个播放终端播放的媒体文件名称，并判断媒体文件被第p个播放终端播放的媒体文件名称是否在第p个播放记录中首次出现，如果服务器获得媒体文件被Q个播放终端播放的媒体文件名称分别在对应的Q个播放记录中首次出现，则确定媒体文件的被首次播放次数为Q次，其中，Q为大于等于1的任一整数，p及Q为大于等于1且小于等于P的整数。
对于Q次被首次播放中的每一次被首次播放，服务器都会判断该被首次播放是否为被完整播放。服务器可以依次取q从1至Q，判断第q次被首次播放是否为被完整播放，当服务器判断Q次被首次播放中有S次被完整播放时，确定媒体文件的被首次完整次数为S次。具体如何判断一次被播放为被完整播放，前文已经做出详细说明，在此就不再赘述。
服务器将被首次完整播放次数S除以被首次播放次数Q，即得到了媒体文件的被播放的第二完整播放率。
需要说明的是，本实施方式中，不限于媒体文件被首次播放，在实际实施中，媒体文件被多次播放时，可以将媒体文件任一次被播放作为首次播放。
在获得了媒体文件被播放的至少一个参数后，可以执行步骤25。
由于媒体文件有多个，所以对于多个媒体文件中的每一个媒体文件，都可以获得每个媒体文件的至少一个参数。对多个媒体文件进行排序，一个媒体文件的排列序号即为该媒体文件的评估结果。
其中，对多个媒体文件进行排序，有且不限于以下几种实施方式：
第一种实施方式，任选至少一个参数中的一个参数，即任选被完整播放次数、第一完整播放率、平均播放率及第二完整播放率中的一个参数，假设选择的一个参数为完整播放次数，则对多个媒体文件的完整播放次数进行排序，一个媒体文件的排列序号即为该媒体文件的评估结果。
第二种实施方式，任选至少一个参数中的部分参数或者全部参数，然后对选择的部分参数或者全部参数进行算数平均，获得每个文件的综合参数，对多个媒体文件的综合参数进行排序，一个媒体文件的排列序号即为该媒体文件的评估结果。
第三种实施方式，任选至少一个参数中的部分参数或者全部参数，按照至少一个参数中每个参数的重要程度，确定每个参数的权重，然后对对选择的部分参数或者全部参数进行加权平均，获得每个文件的综合参数，对多个媒体文件的综合参数进行排序，一个媒体文件的排列序号即为该媒体文件的评估结果。
本发明实施例一中，在获得评估结果之后，可以根据评估结果，进行好友推荐。即根据完整播放次数、第一完整播放率、平均播放率、第二完整播放率的排序结果进行好友推荐通过获得不同播放终端的用户播放媒 体文件的一个参数或多个参数，可以进行好友推荐，播放终端的用户在获得评估结果的同时，还可以获得好友推荐信息，提高了用户体验。
其中，好友推荐具体有以下几种实施方式：
第一种实施方式：多个播放终端的用户播放排名前m名(m为大于1的整数)的媒体文件的排名顺序一致，则向某一个用户推荐其他用户为好友。例如：服务获得用户X完整播放次数(此处也可不限于完整播放次数，还可以是第一完整播放率、平均播放率、第二完整播放率)排名前5名的媒体文件的顺序为S1，S2，S3，S4，S5；如果服务器获得用户Y完整播放总次数(此处需使用相同的参数，例如用户X完整播放次数与用户Y完整播放次数)排名前5名的媒体文件的顺序也为S1，S2，S3，S4，S5，则服务器可向用户X推荐用户Y为好友。
当然，顺序也可以不完全相同。例如：服务器获得用户X播放排名前5名的媒体文件顺序为S1，S2，S3，S4，S5，服务器获得用户Y播放前5名的媒体估文件是S6，S2，S3，S4，S5，用户X与用户Y之间只有排名第一的媒体文件不同，其它四个媒体估文件的顺序都相同，也可以进行推荐。
第二种实施方式：多个播放终端的用户播放排名前m名的媒体文件相同，则向某一个用户推荐其他用户为好友。例如：服务器获得用户X播放排名前5名的媒体文件为S3，S2，S4，S1，S5(可以为任何顺序)，服务器获得用户Y播放排名前5名的媒体文件为S1，S2，S3，S4，S5(可以为任何顺序)，则服务器向用户X推荐用户Y为好友。
第三种实施方式：多个播放终端的用户播放排名前m名的媒体文件中，有n个媒体文件相同或媒体文件的排名相同。例如：服务器获得用户X播放排名前5名的媒体文件为S1，S2，S3，S4，S5(可以为任何顺序)，服务器获得用户Y播放排名前5名的媒体文件为S1，S2，S3，S5，S6(排名可以为任何顺序)；有4个媒体文件相同，则服务器向用户X推荐用户Y 为好友。
实施例二
请参考图3，图3为本发明实施例二中一种评估媒体文件的方法流程图。其中，步骤31为图1中步骤11的具体实现方式，步骤25为图1中步骤12的具体实现方式。具体如下：
步骤31：获得所述媒体文件的被停止播放率；
步骤25：根据所述至少一个参数的大小，对所述媒体文件进行排序，所述排序结果为所述评估结果。
本发明实施例二中，步骤31具体包括：获得所述媒体文件的被播放次数；获得所述媒体文件被停止播放的时刻；根据所述媒体文件被停止播放的时刻，确定所述被停止播放时刻出现的次数；获得所述媒体文件的被停止播放率，所述被停止播放率为所述被停止播放时刻出现的次数除以所述被播放次数。
具体来讲，在媒体文件被播放的过程中，如果用户不想继续欣赏正在播放的媒体文件，用户会停止对媒体文件的播放。服务器即可获得媒体文件的被停止播放时刻。
服务器获得被停止播放时刻有如下两种获得方式。第一种获得方式为：当用户在线播放媒体文件时，通过服务器的播放模块可获得正在播放的媒体文件的被停止播放时刻；第二种获得方式为：当用户利用播放终端播放媒体文件时，服务器的播放模块接收播放终端的播放模块发送的正在播放的媒体文件的被停止播放时刻。
当服务器获得N个相同的被停止播放时刻，则确定媒体文件的该被停止播放时刻出现的次数为N次。
服务器获得媒体文件的被播放次数的方法在前文已经详细说明，在此就不再赘述。
在获得了媒体文件被停止播放时刻出现的次数及媒体文件的被播放次 数后，可以计算停止播放时刻出现的次数占媒体文件的被播放次数的比值，获得媒体文件的被停止播放率。当计算出的比值大于第一预设阈值，则说明则该媒体文件的包含被停止播放时刻的片段不受用户欢迎，需要修改该片段，可以将修改信息发送给媒体文件的作者，媒体文件的作者可以对该片段进行修改。其中，第一预设阈值可以由用户或者播放模块设定，如50％，60％等。
例如：在一个媒体文件被播放的过程中，服务器获得停止播放时刻为：该媒体文件的第2分钟，及该媒体文件的第3分钟，其中，停止播放时刻为该媒体文件的第2分钟出现的次数为60次，停止播放时刻为该媒体文件的第3分钟出现的次数为30次，假设该媒体文件的被播放次数为100次，且第一预设阈值为50％，则停止播放时刻为该媒体文件的第2分钟出现的次数占被播放次数的比值为60％，大于第一预设阈值50％，则说明该媒体文件的包含第2分钟的片段，如2分00秒至2分30秒不受用户欢迎，需要修改该片段，可以将修改信息发送给媒体文件的作者，媒体文件的作者可以对该片段进行修改。而停止播放时刻为该媒体文件的第3分钟出现的次数占被播放次数的比值为30％，小于第一预设阈值50％，则说明该媒体文件的包含第3分钟的片段暂时不需要修改。
在获得媒体文件的被停止播放率后，可以执行步骤25，具体的实施过程可以参考实施例一中的描述，在此就不再赘述。
实施例三
请参考图4，图4为本发明实施例三中一种评估媒体文件的方法流程图。其中，步骤41为图1中步骤11的具体实现方式，步骤25为图1中步骤12的具体实现方式。具体如下：
步骤41：获得所述媒体文件的被播放率；
步骤25：根据所述至少一个参数的大小，对所述媒体文件进行排序，所述排序结果为所述评估结果。
本发明实施例三中，步骤41具体包括：获得所述媒体文件的被播放次数；获取用户的体征参数；确定所述用户的体征参数与所述媒体文件的匹配度；当所述匹配度大于预设阈值时，确定所述用户的体征参数对应的所述媒体文件的被播放时刻；确定所述被播放时刻出现的次数；获得所述媒体文件的被播放率，所述被播放率为所述被播放时刻出现的次数除以所述被播放次数。
服务器获得用户的体征参数有如下两种获得方式。第一种获得方式为：当用户在线播放媒体文件时，利用服务器中的图像采集装置，如摄像头，或者利用服务器中的声音采集装置，如录音机获得用户的体征参数，如用户的动作、表情、声音等。服务器中的图像采集装置或声音采集装置获得用户的体征参数；第二种获得方式为：当用户利用播放终端播放媒体文件时，服务器接收播放终端发送的用户的体征参数。
服务器获得用户的体征参数后，获得媒体文件的被播放时刻的方法为：首先，确定用户的体征参数与媒体文件的匹配程度，如用户是否随媒体文件的播放起舞，或者随媒体文件的播放面部表情发生变化，或者随媒体文件的播放哼唱，然后，判断起舞的强度、面部表情的变化程度或哼唱声音的大小是不是大于预设阈值，也就是判断与媒体文件的匹配程度大于预设阈值的用户的体征参数是否真正因媒体文件的播放而变化的，如果大于预设阈值，则服务器记录用户的体征参数对应的该媒体文件的被播放时刻。
当服务器获得N个相同的被播放时刻，则确定媒体文件的该被播放时刻出现的次数为N次。
例如：在一个媒体文件被播放的过程中，利用声音采集装置，如录音机获得用户的声音大小为20分贝，即用户未发出任何声音等，当检测到媒体文件播放到第3分钟时刻用户发出哼唱，并且哼唱声音的大小为50分贝，大于预设阈值55分贝，则记录被播放时刻为该媒体文件的第3分钟时刻，就获得被播放时刻为该媒体文件的第3分钟时刻出现的次数为1次，如果 另一用户也在该媒体文件播放到第3分钟时刻用户发出哼唱，并且哼唱声音的大小大于预设阈值，则获得被播放时刻为该媒体文件的第3分钟时刻出现的次数为2次。
服务器获得媒体文件的被播放次数的方法在前文已经详细说明，在此就不再赘述。
在获得了媒体文件被播放时刻出现的次数及媒体文件的被播放次数后，可以计算播放时刻出现的次数占媒体文件的被播放次数的比值，获得媒体文件的被播放率。当计算出的比值大于第二预设阈值，则说明则该媒体文件的包含被停止播放时刻的片段受用户欢迎。其中，第二预设阈值可以由用户或者播放模块设定，如50％，60％等。
例如：在一个媒体文件被播放的过程中，服务器获得多个用户随媒体文件的播放开始哼唱的声音大小大于预设阈值的播放时刻为该媒体文件的第2分钟，播放时刻为该媒体文件的第2分钟出现的次数为60次，假设该媒体文件的被播放次数为100次，且第二预设阈值为50％，则停止播放时刻为该媒体文件的第2分钟出现的次数占被播放次数的比值为60％，大于第二预设阈值50％，则说明该媒体文件的包含第2分钟的片段，如2分00秒至2分30秒受用户欢迎。
在获得媒体文件的被播放率后，可以执行步骤25，具体的实施过程可以参考实施例一中的描述，在此就不再赘述。
实施例四
请参考图5，图5为本发明实施例四中一种评估媒体文件的方法流程图。其中，步骤51为图1中步骤11的具体实现方式，步骤52为图1中步骤12的具体实现方式。具体如下：
步骤51：获得播放终端关注的其他用户播放所述媒体文件的被播放的至少一个参数；
步骤52：对所述播放终端关注的其他用户播放所述媒体文件的被播放 的至少一个参数进行评估，获得评估结果。
本发明实施例四中，播放终端关注的其他用户为：一个播放终端的用户将在社交网络中的联系人或者电话通讯录中的联系人、或者喜欢的明星、或者喜欢的评论家设置为关注用户。
本发明实施例四中，服务器可以仅获得关注用户播放媒体文件的被播放的至少一个参数，而不需要获得全部用户播放的媒体文件的被播放的至少一个参数，一方面，提高了获得媒体文件被播放的至少一个参数的效率，进而提高了对媒体文件进行评估的效率。
例如：以至少一个参数为平均播放率为例，假设播放终端的用户的关注用户有用户A、用户B及用户C，用户A播放了2个媒体文件：媒体文件A1，媒体文件A2，用户B播放了2个媒体文件：媒体文件B1，媒体文件B2，用户C播放了2个媒体文件：媒体文件C1，媒体文件C2，服务器的处理器获得媒体文件A1，媒体文件A2，媒体文件B1，媒体文件B2，媒体文件C1，媒体文件C2的平均播放率依次为90％、30％、80％、70％、60％、40％。
服务器根据获得的播放终端关注的其他用户播放的媒体文件的被播放的至少一个参数的大小，对媒体文件进行排序，排序结果即为评估结果。
仍以上述例子为例，服务器的处理器已经获得了媒体文件A1，媒体文件A2，媒体文件B1，媒体文件B2，媒体文件C1，媒体文件C2的平均播放率依次为90％、30％、80％、70％、60％、40％，那么服务器的处理器根据平均播放率的大小，对媒体文件的排序为：A1、B1、B2、C1、C2、A2。
播放终端的用户可以获得关注的其他用户播放的媒体文件的评估结果，提供了针对播放终端的用户的个性化的评估结果，可以根据排序获知自己的关注用户目前正在播放哪些媒体文件，哪些媒体文件在自己的关注用户中受欢迎。也可以根据排序结果从众多媒体文件中选择播放哪些媒体文件。提高了用户体验。
接下来介绍播放终端执行本发明实施例提供的评估媒体文件的方法的详细过程。
当用户利用播放终端播放媒体文件时，播放终端可以获得媒体文件被播放的至少一个参数，然后根据获得的至少一个参数，评估所述媒体文件，获得评估结果。具体播放终端如何获得媒体文件被播放的至少一个参数及如何评估媒体文件，请参考前文服务器执行评估媒体文件方法的过程，在此就不详细赘述。
