附图说明 BRIEF DESCRIPTION

[0007] 此处所说明的附图用来提供对本发明的进一步理解,构成本申请的一部分,本发明的示意性实施例及其说明用于解释本发明,并不构成对本发明的不当限定。 [0007] The drawings described herein are provided for further understanding of the present invention, constitute a part of this application, exemplary embodiments of the present invention are used to explain the present invention without unduly limiting the present invention. 在附图中: In the drawings:

[0008] 图1所示为根据本发明的较佳实施例提供的实现云教育平台数据搜索的方法的流程图; It is a flowchart of a method to cloud data relevant educational platform according to an [0008] Figure 1 according to a preferred embodiment of the present invention;

[0009] 图2所示为根据本发明的较佳实施例提供的实现云教育平台数据搜索的系统的示意图。 Is a schematic view [0009] FIG. 2 in accordance with the preferred embodiment of the present invention to cloud data relevant educational system platform provided by the embodiment.

具体实施方式 detailed description

[0010] 下文中将参考附图并结合实施例来详细说明本发明。 [0010] Hereinafter with reference to the accompanying drawings and embodiments of the present invention will be described in detail. 需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。 Incidentally, in the case of no conflict, embodiments and features of the embodiments of the present application can be combined with each other.

[0011] 图1所示为根据本发明的较佳实施例提供的实现云教育平台数据搜索的方法的流程图。 Methods Cloud education platform implementation provides data relevant to the preferred embodiment according to the present embodiment of the invention shown in a flowchart of [0011] FIG. 如图1所示,本发明的较佳实施例提供的实现云教育平台数据搜索的方法包括步骤101~104。 1, the preferred method of the present invention to cloud data relevant educational platform according to an embodiment comprises the steps 101 to 104.

[0012] 于步骤101,数据处理服务器无限循环遍历教学数据存储器内的数据,根据其维护的GUID列表,按照第一规则,获得专题数据,并将所述专题数据存储至专题数据存储器。 [0012] In step 101, the data processing server through the data an infinite loop within the teaching data memory, based on the list maintained by its GUID, in accordance with a first rule, obtained thematic data, said topic data and topic data stored in the memory.

[0013] 于本实施例中,教学数据存储器存储云教育平台上的教学数据。 [0013] embodiment, the teaching data on the teaching data memory store in this embodiment internet cloud education. 具体而言,云教育平台上的老师会将教学课件存储至教学数据存储器的教学课件专区,然后,老师在授课时实时录制的视频亦可存储至教学数据存储器的教学视频专区。 Specifically, courseware courseware area teachers will be teaching data stored in memory on the cloud platform of education, then, the teacher in teaching real-time video recording can also be stored in the data memory instructional video teaching area. 学生在线听课,并在听完课之后给老师评分,评分结果可存储至教学数据存储器的学生评分专区。 Students online lectures, and after listening to the teacher in class score, score results can be stored in the data memory of teaching students scoring area. 老师布置作业,并将作业存储至教学数据存储器的学生作业专区。 Teacher assignments, and the job of teaching data stored in the memory of student work area. 学生完成作业,老师例如通过云教育平台批阅后,将作业得分存储至教学数据存储器的作业得分专区。 Students complete the job, for example, after marking the teacher education through a cloud platform to store teaching job score data memory job scoring area. 此外,老师亦会总结本节课程的主要内容,并输入相应的关键词作为元数据。 In addition, the teacher will summarize the main content of the lesson and enter the appropriate keywords as metadata. 其中,云教育平台会为每节课程生成一个全局唯一的编号,用于标识该节课程的所有资源(例如,课件、视频、评分、作业、得分、元数据)。 Among them, the cloud platform will provide education lesson each thread to create a globally unique number that identifies the lesson all resources used (for example, courseware, video, scores, assignments, scores, metadata). 举例而言,若老师A准备"信息系统的生命周期"的课程,当老师A制作教学课件并上传至教学数据存储器后,云教育平台会为该课件产生一个全局唯一的编号GuiDmHSAeAs-Tsee-dfTe-bcog-Oecf^eaddege,该教学课程之后产生的教学视频、学生评分、学生作业、作业得分、元数据等教学数据都会采用al484645-786e-4f7e-bc09-0ecf36add696作为⑶ID编号, 以便于专题数据整理。 For example, if A teacher ready "information system life cycle" of course, when the teaching data memory A teacher courseware produced and uploaded to the cloud platform for education will have a globally unique number GuiDmHSAeAs-Tsee-dfTe for courseware -bcog-Oecf ^ eaddege, teaching instructional video data generated after the curriculum, student scores, student work, work score, metadata, etc. will adopt al484645-786e-4f7e-bc09-0ecf36add696 as ⑶ID number in order to organize thematic data .

[0014] 于本实施例中,数据处理服务器无限循环遍历教学数据存储器内的数据,根据其维护的⑶ID列表,按照第一规则,获得专题数据的过程为:数据处理服务器无限循环遍历教学数据存储器内的数据,获取数据的GUID,并比对GUID是否存在于GUID列表,若不存在,则获取GUID对应的数据归档为专题数据。 Process [0014] In the present embodiment, the data processing server through the data an infinite loop within the teaching data memory, according to its list ⑶ID maintained, according to a first rule, thematic data obtained as: a data processing server infinite loop through the teaching data memory data in, obtain the GUID of the data and compare whether GUID GUID exists in the list, if it exists, the corresponding data is acquired GUID filed for thematic data. 具体而言,数据处理服务器维护GUID列表,若数据处理服务器在教学数据存储器内获取的数据GUID存在于GUID列表,则说明该数据已经被提取,如果该数据的GUID未存在于GUID列表中,则说明该数据未被提取,此时,数据处理服务器将教学数据存储器内的该GUID对应的教学数据均提取出来,并归档至一个静态文件,形成一条专题数据,且将该专题数据存储于专题数据存储器。 Specifically, the data processing server maintains a list GUID, if the data processing server of the acquired data in the teaching data memory GUID GUID is present in the list, it indicates that the data has been extracted, if the GUID data is not present in the GUID list, the extracted data is not described, this time, the data processing server corresponding to the instruction data to the GUID in the teaching data memory are extracted and archived to a static file, forming a thematic data, and the data is stored in topic data thematic memory. 同时,完成该GUID对应的教学数据的提取后,数据处理服务器会将该GUID更新至其维护的GUID列表。 At the same time, teaching extract data corresponding to the GUID is completed, the data processing server to update the list of GUID GUID its maintenance. 于此,每个专题数据例如包括编号GUID、教学课件、教学视频、学生评分、学生作业、作业得分、元数据等教学数据。 This, each topic includes data such as number GUID, courseware, instructional videos, student scores, student jobs, job scores, teaching and other metadata.

[0015] 于步骤102,所述数据处理服务器无限循环遍历所述专题数据存储器内的专题数据,并根据所述专题数据生成专题数据索引表。 [0015] In step 102, the data processing server infinite loop through thematic data within the data store topics, topic data and generates an index table according to the thematic data.

[0016] 于本实施例中,专题数据索引表包括序号、专题GUID、物理位置、元数据及词句数据等内容。 [0016] In the present embodiment, the index table includes thematic data content ID, the GUID topic, physical location, the metadata expressions and data. 具体而言,数据处理服务器无限循环遍历专题数据存储器内的专题数据,并比对专题数据的GUID是否存在于专题数据索引表中,若存在,说明此专题数据已被提炼至专题数据索引表中,若不存在,则说明该专题数据尚未被提炼至专题数据索引表中,此时需要将该专题数据的相关信息加入专题数据索引表。 Specifically, the data processing server infinite loop through topics in the topic data store the data, and match the GUID thematic data exists in the index table thematic data, if present, indicating that this data has been refined to the topic thematic data index table , if present, it indicates that the data has not been refined to the topic thematic data index table, the information required at this time the topic data is added thematic data index table. 于此,专题数据索引表例如表1所示。 Thereto, the topic data-index table as shown in Table 1.
