Description

信息屏蔽方法及系统 技术领域
本发明涉及信息处理领域，尤其涉及一种在考试过程中屏蔽信息的方法及系统。
背景技术
随着网络教学的不断普及，网络授课的方式因不受时间和地点的约束，可方便地供用户根据其自身的需求而随时随地采用。在网络教学的过程中，为了了解学生学习效果，一般会设置考试环节，以对学生的课程学习进行评价。这种在用户终端上进行的考试，为了保证学生考试成绩的真实性，一般会采取在不联网的情况下进行考试，以避免在考试过程中考生通过网络查找考试答案。但随着输入法的不断改进，输入法的智能联想功能越来越简化人们的输入操作，人们一般输入某个词语的字符序列，输入法在展现该词语的同时，还会展示与该词语有相似字符序列组成的其他词语以及该词语之后的联想词，这种输入词语联想功能，容易导致由于输入法的联想功能，而将考试的相关答案带出的问题。例如，语文考试中，要求考生填写诗句“朝辞白帝______，千里江陵______”中空白处的内容，在使用带有联想功能输入法进行输入时，考生仅需要输入“zhaocib”，输入法便会联想出“朝辞”、“朝辞吧”、“照此”、“朝辞白帝彩云间”等内容，由此便将诗句“朝辞白帝彩云间”的内容泄露。为了避免输入法的联想功能对考试所带来的弊端，需要对输入法的输出词语设置屏蔽功能。
现有技术中关于输出词语的屏蔽功能，往往采用直接屏蔽敏感词的方式。例如，根据用户的输入内容，获取该输入内容的多个候选词，判断该候选词是否为预设屏蔽词，如果是预设屏蔽词，则对候选词采用不显示的处理方式。但将这种方式直接用于网络考试中的问题是，虽然可以避免输出敏感词，但也会导致考生无法输出相应的答案。例如，考题答案为“彩云间”，但由于将“彩云间”设置为敏感词，使得考生即便知晓答案，也因该词语被屏蔽而无法输出。
现有技术中另一种可采用的方式是将考试系统中所使用的输入法选为不具联想功能的输入法。这种方式虽然可以避免在考试过程中因输入法的联想功能而将答案泄露，但用户也会因输入法无联想功能而降低答题速度，进而可能影 响考试成绩。
又或者，现有技术考虑针对考试答案涉及的文字内容，将输入法所使用的词库进行重新设计，将考试答案的文字内容中存在上下文关系的词语不进行关联，即取消它们之间的关联性，从而不会将答案内容作为联想词被自动输出。但这种对词库进行重新设计的方法，需要在每次考试时都对词库进行更新，从而导致了工作繁琐。
因此，有必要在考试系统中提供一种信息屏蔽方法，该方法既不影响输入法正常的联想功能，也无需重新设计输入法所使用的词库，便可以起到屏蔽与考试信息相关的联想词语的作用。
发明内容
为此，本发明所要解决的技术问题是如何在考试过程中，在不修改输入法词库的情况下，对考试内容所涉及的词语进行联想屏蔽。

具体实施方式
在更加详细地讨论示例性实施例之前应当提到的是，一些示例性实施例被描述成作为流程图描绘的处理或方法。虽然流程图将各项操作描述成顺序的处理，但是其中的许多操作可以被并行地、并发地或者同时实施。此外，各项操作的顺序可以被重新安排。当其操作完成时所述处理可以被终止，但是还可以具有未包括在附图中的附加步骤。
在上下文中所称“学生端”或“教师端”即为“计算机设备”，是指可以通过运行预定程序或指令来执行数值计算和/或逻辑计算等预定处理过程的智能电子设备，其可以包括处理器与存储器，由处理器执行在存储器中预存的存续指令来执行预定处理过程，或是由ASIC、FPGA、DSP等硬件执行预定处理过程，或是由上述二者组合来实现。
所述计算机设备包括用户设备和/或网络设备。其中，所述用户设备包括但不限于电脑、智能手机、PDA等；所述网络设备包括但不限于单个网络服务器、多个网络服务器组成的服务器组或基于云计算(Cloud Computing)的由大量计算机或网络服务器构成的云，其中，云计算是分布式计算的一种，由一群松散耦合的计算机集组成的一个超级虚拟计算机。其中，所述计算机设备可单独运行来实现本发明，也可接入网络并通过与网络中的其他计算机设备的交互操作来实现本发明。其中，所述计算机设备所处的网络包括但不限于互联网、广域网、 城域网、局域网、VPN网络等。
需要说明的是，所述用户设备、网络设备和网络等仅为举例，其他现有的或今后可能出现的计算机设备或网络如可适用于本发明，也应包含在本发明保护范围以内，并以引用方式包含于此。
在此，本领域技术人员应能理解，本发明可应用于移动端与非移动端，例如，当用户使用手机或PC时，均可利用本发明所述的方法或装置来进行提供与呈现。
这里所公开的具体结构和功能细节仅仅是代表性的，并且是用于描述本发明的示例性实施例的目的。但是本发明可以通过许多替换形式来具体实现，并且不应当被解释成仅仅受限于这里所阐述的实施例。
这里所使用的术语仅仅是为了描述具体实施例而不意图限制示例性实施例。除非上下文明确地另有所指，否则这里所使用的单数形式“一个”、“一项”还意图包括复数。还应当理解的是，这里所使用的术语“包括”和/或“包含”规定所陈述的特征、整数、步骤、操作、单元和/或组件的存在，而不排除存在或添加一个或更多其他特征、整数、步骤、操作、单元、组件和/或其组合。
还应当提到的是，在一些替换实现方式中，所提到的功能/动作可以按照不同于附图中标示的顺序发生。举例来说，取决于所涉及的功能/动作，相继示出的两幅图实际上可以基本上同时执行或者有时可以按照相反的顺序来执行。
下面结合附图对本发明作进一步详细描述。
图1示出了本发明的信息屏蔽方法的流程图，包括S101屏蔽词词库建立步骤、S102屏蔽词词库获取步骤、S103字符序列获取步骤、S104屏蔽联想词确定步骤、S105可显示词语输出步骤。
在步骤S101，建立屏蔽词词库。获取某一考试的试题答案，并对该考试的试卷设置试卷编号。根据试题答案，对答案的文字内容进行分析，将分析出来的具有上下文关系的词作为关联词语，建立屏蔽词词库，并存储到教学服务器中。所述屏蔽词词库具有与相应试卷编号对应的词库编号，所述屏蔽词词库中存有关联词语本身及它们之间的关联关系。
步骤S102，进入考试系统，获取屏蔽词词库。当考生在学生端进入考试系统后，选择要完成的考试试卷。学生端根据该试卷的试卷编号，从教学服务器 获取属于该试卷的屏蔽词词库。具体地，学生端根据考生所选择的试卷，获取该试卷的试卷编号，并将该试卷编号发送给教学服务器，教学服务器在接收到试卷编号后获取该试卷的屏蔽词词库编号，进而获得屏蔽词词库。其中，学生端通过网络向服务器发送试卷编号，所述网络包括但不限于互联网、广域网、城域网、局域网、VPN网络、无线自组织网络(Ad Hoc网络)等。
步骤S103，获取用户输入的字符序列。在步骤S103中，考生通过任何一种可与学生终端进行人机交互的交互设备来输入其想要输入的字符序列，该交互设备可以是键盘、鼠标、遥控器、触摸板或声控设备等。以键盘为例，用户通过键盘在学生终端所显示的输入框中输入想要输入的序列，例如，输入“zhaocib”。
步骤S104，根据输入的字符序列，确定需要屏蔽的联想词。
步骤S1041，根据输入的字符序列获取基础词和联想词。
具体地，针对所述当前输入序列，学生端所使用的输入法根据分析，在其所使用的联想词库中查找与所述当前输入序列相匹配的词语信息。所述联想词库为输入法所使用的词库，所述输入匹配方式包括但不限于前缀匹配。例如，当考生在输入框的当前输入序列为“zhaocib”，学生端查询联想词库后获得的前缀与“zhaocib”相匹配信息包括：“照此办”、“朝辞白帝彩云间”、“朝辞吧”、“朝辞”、“照此”等等信息。从考生输入的内容可以看出，输入法所匹配出的上述内容中，其中“朝辞”、“照此”为根据输入序列完全匹配出来的词语，我们把这种词语称为“基础词”。而匹配内容中的“照此办”、“朝辞白帝彩云间”、“朝辞吧”则属于根据输入序列联想出来的“联想词”。
步骤S1042，对所确定的联想词进行分词处理，获取关联词。
对所确定的联想词进行分词处理，联想词中的基础词与其它词语进行拆分，将与基础词相邻的词语作为“关联词”。例如，用户输入的序列“zhaocib”的联想词包括“照此办”、“朝辞白帝彩云间”、“朝辞吧”，经过分词处理，获得与基础词“朝辞”、“照此”相邻的关联词包括“办”、“白帝”和“吧”。
步骤S1043，确认所获取的关联词是否存在于屏蔽词词库中，并将存在于屏蔽词词库中的关联词所对应的联想词作为需要屏蔽的词语。
在上例中，根据所获取的基础词“朝辞”和“照此”在屏蔽词词库中查找， 与上述基础词存在关联关系的关联词。经过查找，屏蔽词词库中“朝辞”与“白帝”互为关联词语，进一步地，词库中“白帝”与“彩云”也属于关联词语。因此将“朝辞”所涉及的联想词“朝辞白帝彩云间”作为需要屏蔽的屏蔽词，提供给学生端的相应处理模块。
步骤S105，输出可显示的词语。将输入字符序列所对应的词语中除需要屏蔽的联想词之外的词语，作为可显示的联想词信息提供内考生。例如，将“照此办”、“朝辞吧”、“朝辞”、“照此”等联想词信息作为最终可显示给考生的联想词信息。
图2示出了根据本发明实施例的信息屏蔽系统。该系统包括学生端1、教师端2和教学服务器3。
教学服务器3中存有考生试卷的屏蔽词词库。
在进行考试前，教师端2获取某一考试的试题答案及该考试的试卷编号。根据试题答案，对答案的文字内容进行分析，将分析出来的具有上下文关系的词作为关联词语，建立屏蔽词词库，并存储到教学服务器3中。所述屏蔽词词库具有与相应试卷编号对应的词库编号。
学生端1包括输入单元11、屏蔽词词库获取单元12、屏蔽词确认单元13、输出单元14。
当考生通过学生端1进入考试系统后，考生选择要完成的考试试卷，屏蔽词词库获取单元12获取屏蔽词词库。具体地，屏蔽词词库获取单元12根据考生选择的试卷，获取试卷编号并将该试卷编号发送给教学服务器3。教学服务器3接收到试卷编号后获取该试卷的屏蔽词词库编号，进而获得屏蔽词词库。将该屏蔽词词库发送给屏蔽词词库获取单元12。
输入单元11获取考生输入的字符序列。考生可通过任何一种可与学生终端进行人机交互的交互设备来输入其想要输入的字符序列，该交互设备可以是键盘、鼠标、遥控器、触摸板或声控设备等。以键盘为例，用户通过键盘在学生终端所显示的输入框中输入想要输入的序列，例如，输入“zhaocib”。
屏蔽词确认单元13根据输入的字符序列，确定需要屏蔽的联想词。
首先，根据输入的字符序列获取基础词和联想词。
具体地，针对所述当前输入序列，学生端所使用的输入法根据分析，在其所使用的联想词库中查找与所述当前输入序列相匹配的词语信息。所述联想词库为输入法所使用的词库，所述输入匹配方式包括但不限于前缀匹配。例如，当考生在输入框的当前输入序列为“zhaocib”，学生端查询联想词库后获得的前缀与“zhaocib”相匹配信息包括：“照此办”、“朝辞白帝彩云间”、“朝辞吧”、“朝辞”、“照此”等等信息。从考生输入的内容可以看出，输入法所匹配出的上述内容中，其中“朝辞”、“照此”为根据输入序列完全匹配出来的词语，我们把这种词语称为“基础词”。而匹配内容中的“照此办”、“朝辞白帝彩云间”、“朝辞吧”则属于根据输入序列联想出来的“联想词”。
接下来，对所确定的联想词进行分词处理，获取关联词。
屏蔽词确认单元13对所确定的联想词进行分词处理，联想词中的基础词与其它词语进行拆分，将与基础词相邻的词语作为“关联词”。例如，用户输入的序列“zhaocib”的联想词包括“照此办”、“朝辞白帝彩云间”、“朝辞吧”，经过分词处理，获得与基础词“朝辞”、“照此”相邻的关联词包括“办”、“白帝”和“吧”。
最后，确认所获取的关联词是否存在于屏蔽词词库中，并将存在于屏蔽词词库中的关联词所对应的联想词作为需要屏蔽的词语。
在上例中，根据所获取的基础词“朝辞”和“照此”在屏蔽词词库中查找，与上述基础词存在关联关系的关联词。经过查找，屏蔽词词库中“朝辞”与“白帝”互为关联词语，进一步地，“白帝”与“彩云”也属于关联词语。因此将“朝辞”所涉及的联想词“朝辞白帝彩云间”作为需要屏蔽的屏蔽词，由屏蔽词确认单元13提供给输出单元14。
根据屏蔽词确认单元13提供的屏蔽词，输出单元14输出可显示的词语。具体地，输出单元14将输入字符序列所对应的词语中除需要屏蔽的联想词之外的词语，作为可显示的联想词信息提供内考生。例如，将“照此办”、“朝辞吧”、“朝辞”、“照此”等联想词信息作为最终可显示给考生的联想词信息。
本领域普通技术人员可以理解上述实施例的各种方法中的全部或部分步骤是可以通过计算机程序来指令相关的硬件来完成，该程序可以存储于一计算机可读存储介质中，并由处理器执行。计算机可读存储介质可以包括：只读存储 器(ROM，Read Only Memory)、随机存取存储器(RAM，Random Access Memory)、磁盘或光盘等。
