Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and not limitation. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
The data recommendation method provided in the embodiments may be executed by a data recommendation device, which may be implemented in software and/or hardware and integrated in a data recommendation device. It can be understood that the data recommendation device may be an intelligent device used by a student in a network teaching scene, and may be a background server providing services for the intelligent device used by the student. In the embodiment, the data recommendation device is taken as a background server for description, and the intelligent device used by the student is called a student end, and at this time, the student end includes but is not limited to intelligent devices such as a tablet computer, a mobile phone, and a learning machine.
Typically, the background server is in data communication with the student side to provide the student side with the network teaching service. Furthermore, in order to facilitate the parents to master the learning condition of the student, a home agent end may be further provided, where the home agent end includes but is not limited to an intelligent device used by the parents, such as a mobile phone and a tablet computer, that is, an application program with a control function is installed in the intelligent device used by the parents, and the application program communicates with the backend server, so that the parents can obtain the learning condition of the student end through the backend server.
Fig. 1 is a flowchart of a data recommendation method according to an embodiment of the present application. Referring to fig. 1, the data recommendation method specifically includes:
and 110, when a data acquisition instruction is received, acquiring a teaching content data set and recommendation reference data, wherein the recommendation reference data comprises at least one of recommendation categories, student position data and behavior data, the recommendation categories are set by associated control equipment, and the behavior data is behavior data generated when a student browses historical teaching content.
Specifically, when a student starts network teaching through a student end to learn online, the student end acquires teaching resources from the data recommendation device, and at the moment, a resource acquisition instruction sent by the student end can be understood as a data acquisition instruction.
Further, the teaching content data set refers to a data set composed of teaching contents, wherein the teaching contents can also be understood as teaching resources. The teaching content can be live video for teacher teaching, recorded video for teacher teaching, exercise collection, teaching notes and other contents. In the embodiment, a live video in which teaching contents are used as teachers for teaching is taken as an example. At the moment, when the student side confirms that the live video playing function is entered, a data acquisition instruction is sent to the data recommendation equipment, and when the data recommendation equipment receives the data acquisition instruction, a teaching content data set is acquired. Alternatively, when the educational content data set is obtained, the current latest live video may be obtained and the educational content data set is composed. In practical applications, live videos meeting other conditions may also be obtained and composed into an educational content data set, which is not limited in the embodiment. Typically, each live video in the teaching content data set may have a corresponding tag, where the tag content may be set according to an actual situation, for example, the tag records live subject, applicable grade, knowledge point of explanation, and applicable teaching material version. The tag content can be added by a teacher explaining live videos or automatically added by data recommendation equipment.
Since the live video in the acquired teaching content data set may not be completely suitable for the student side, the live video suitable for the student side needs to be selected and recommended to the student side. In an embodiment, live video suitable for a student side is selected by recommending reference data. Each student end has corresponding recommended reference data, and the specific content of the recommended reference data can be set according to actual conditions. In an embodiment, the set recommendation reference data includes at least one of a recommendation category, student location data, and behavior data.
The recommendation category contains knowledge points applicable to the student side, each knowledge point can be considered as a category, and the recommendation category is set by the associated control device, wherein the associated control device can also be understood as the parent side, that is, the knowledge points applicable to the student side are set by the parent side. It can be understood that the embodiment of the method for setting the recommendation category by the parent end is not limited, for example, the parent end sets the recommendation category according to the current learning content and the mastery degree of the student, and for example, the parent end obtains a live video historically browsed by the student end and sets the recommendation category according to the live video historically browsed by the student end.
The student position data refers to the geographical position data of the student, and the embodiment of the determination method is not limited. For example, the student end adds the student position data and reports the student position data to the data recommendation device, and for example, when the student end communicates, the student position data is obtained through the positioning function of the student end. For another example, when communicating with the student terminal, if the student terminal is detected to be WiFi connected, the student location data is acquired through the WiFi network.
The behavior data is behavior data generated when the student uses the student side to browse the historical teaching contents (live video). The historical teaching content can be live videos played by the student end in the previous network teaching process or live videos played by the student end within a set time length. When the student end watches the live video, operation behaviors such as searching, praise, comment and attention can be sent out, and at the moment, behavior data can be obtained according to the operation behaviors and the browsing records. Optionally, the behavior data may be generated by the data recommendation device by acquiring the operation behavior of the student side, or may be generated by the student side based on the operation behavior and sent to the data recommendation device.
And 120, selecting target teaching contents in the teaching content data set according to the recommended reference data.
Specifically, according to the recommended reference data, the teaching content (live video) suitable for the student side can be selected from the teaching content data set and recorded as the target teaching content. Wherein the target teaching content may be composed of a plurality of live videos. Optionally, the maximum number of live videos in the target teaching content is preset, and when the number of live videos applicable to the student end exceeds the maximum number, the live videos can be deleted. Alternatively, live video suitable for the student side is selected in the tutorial content dataset based on the maximum number.
It can be understood that the way of determining the target teaching content is different when the recommendation reference data contains different contents.
In a first example, when the recommendation reference data includes a recommendation category, a live video suitable for the recommendation category may be selected from the teaching content data set, that is, a live video having the same knowledge points as those included in the recommendation category is selected, and all or part of the live videos obtained by the selection may be used as the target teaching content.
In the second example, when the recommended reference data includes student position data, a teaching material version used in a region where the recommended reference data is located may be determined based on the student position data, then, a live video using the teaching material version is selected in the teaching content data set, that is, a live video of a teaching material version suitable for the region where the student is located is selected according to the teaching material version recorded in a tag of each live video, and then, all or part of the selected live videos are used as target teaching content.
And in the third example, when the recommended data comprises behavior data, determining live videos (such as commented and concerned live videos) of the student end in the historical network teaching process based on the behavior data to further determine knowledge points corresponding to the live videos of the student end, selecting the live videos corresponding to the knowledge points in the teaching content data set through tags, and then taking all or part of the selected live videos as target teaching content.
And in the fourth example, when the recommended reference data includes any two of recommended categories, student position data and behavior data, the teaching content data set can be screened for one time based on one recommended reference data to select a proper live video, and then the screened live video is screened for another time based on another recommended reference data to obtain the target teaching content. The method can also be used for screening the teaching content data sets once respectively based on two kinds of recommended reference data, each kind of recommended reference data corresponds to one data set at the moment, and then a certain number of live videos are selected from each data set to form the target teaching content. It can be understood that, when a certain number of live videos are selected from the two data sets, the number ratio corresponding to each data set may be set according to an actual situation, and the embodiment is not limited. For example, when the recommendation reference data includes a recommendation category and student position data, a live video suitable for the recommendation category may be selected from the teaching content data set based on the recommendation category (in the same manner as described in example one), and a live video suitable for the student position data may be selected again from the selected live videos (in the same manner as described in example two), so as to constitute the target teaching content. And selecting live videos suitable for student position data in the teaching content data set, and then selecting live videos suitable for recommended categories again in the selected live videos to form target teaching content. Or selecting live videos suitable for student position data and live videos suitable for recommendation categories in the teaching content data sets respectively, wherein the student position data corresponds to one data set, the recommendation categories correspond to one data set, and then selecting the live videos in the two data sets to form target teaching content. For another example, when the recommendation reference data includes a recommendation category and behavior data, a live video suitable for the recommendation category may be selected from the instructional content data set based on the recommendation category (in the same manner as described in example one), and a live video suitable for the behavior data may be selected again from the selected live videos (in the same manner as described in example three), so as to form the target instructional content. Or selecting live videos suitable for behavior data in the teaching content data set, and then selecting live videos suitable for recommended categories again in the selected live videos to form the target teaching content. Or selecting live videos suitable for behavior data and live videos suitable for recommendation categories in the teaching content data sets respectively, wherein the behavior data corresponds to one data set, the recommendation categories correspond to one data set, and then selecting the live videos in the two data sets to form the target teaching content.
Example five, the recommendation reference data includes a recommendation category, student location data, and behavior data. At this time, the priority relationship of the three types of recommended reference data can be set, firstly, the teaching content data set is screened once based on the recommended reference data with the highest priority, a proper live broadcast video is selected to form one data set, then, the data set is screened again based on the recommended reference data with the next highest priority, a proper live broadcast video is selected to form another data set, and finally, the another data set is screened again based on the recommended reference data with the lowest priority to obtain the target teaching content. The method can also be used for firstly screening the teaching content data sets once based on the three recommended reference data to obtain three data sets, and then selecting a certain number of live videos in each data set to form the target teaching content. It can be understood that, when a certain number of live videos are selected from the three data sets, the number proportion corresponding to each data set may be set according to actual conditions, and the embodiment is not limited. The manner of selecting the live video based on the recommended reference data may refer to the selection manner of the live video described in the corresponding example one to example three.
And step 130, recommending the selected target teaching content to the student.
Typically, the obtained target teaching content is returned to the student. Optionally, the live videos in the target teaching content are sorted, the sorted target teaching content is returned to the student side, and at this time, the sorted target teaching content is displayed in a home page of a live function of the student side. The sorting rule can be set according to actual conditions, for example, the live video is sorted according to data such as the number of viewers, the number of attention people or the number of subscribers.
After receiving the target teaching content, the student end can select the required live broadcast video to carry out online learning.
The technical problem that the required teaching content cannot be pertinently recommended to the students in the prior art can be solved by the technical means that when a data acquisition instruction is received, the teaching content data set and the recommendation reference data are acquired, wherein the recommendation reference data comprise at least one of recommendation categories, student position data and behavior data, then the target teaching content is selected in the teaching content data set according to the recommendation reference data, and the target teaching content is recommended to the students. Through the recommendation categories set by the household terminal, the teaching contents corresponding to the knowledge points set by the parents can be recommended to the student terminal, and the condition that inapplicable teaching contents are recommended to the student due to low recognition degree of the student on the knowledge points is avoided. Through the student position data, the teaching content adaptive to the teaching version of the area can be recommended to the student end, and the condition that the teaching content of different teaching versions is recommended to the student so that the student cannot learn in a contrast mode is avoided. Knowledge points of student key learning can be determined through behavior data, and then relevant teaching contents are recommended. The recommendation method is more accurate than recommending teaching contents based on browsing records. Because the recommended teaching content is more suitable for students, the students can learn the needed content more pertinently and purposefully.
On the basis of the above embodiment, the recommendation reference data includes a recommendation category. At this time, the recommendation category needs to be set by the associated control apparatus (i.e., the home agent). Correspondingly, in order to enable the parent end to set a reasonable recommendation category, the historical teaching content of the student end can be sent to the parent end, so that the parent end sets the recommendation category according to the historical teaching content. Accordingly, the setting data recommendation method includes steps 210 to 230:
and step 210, acquiring historical browsing records of the students browsing historical teaching contents.
The history browsing record refers to the record of the history teaching content browsed by the student terminal. The history browsing record may contain links, tags and the like of the live video.
Optionally, the data recommendation device may record the historical teaching content browsed by the student side and generate a historical browsing record, or the student side may generate the historical browsing record and send the historical browsing record to the data recommendation device.
Step 220, sending the historical browsing record to the control device, so that the control device sets a recommendation category according to the historical browsing record.
Specifically, the data recommendation device records the corresponding relationship between the student terminal and the parent terminal, and after the history browsing record is acquired, the history browsing record can be sent to the parent terminal. Optionally, the data recommendation device may periodically obtain the historical browsing records and send the historical browsing records to the parent end, so that the parent can regularly view the teaching contents browsed by the student end through the parent end. The acquisition period of the historical browsing records can be set according to actual conditions. Or when the fact that the household terminal is on line is detected, the history browsing record is obtained and sent to the household terminal.
After the parent end receives the historical browsing record, the teaching content recently browsed by the student end can be determined according to the historical browsing record. Then, the parent end can determine which teaching contents are helpful for the learning of the student and which are not helpful for the learning of the student in the teaching contents recently browsed by the student end, and set knowledge points suitable for the student to obtain the recommendation categories. The specific operation mode embodiment when the parent end sets the recommendation category is not limited. And after the household terminal finishes setting the recommendation category, returning the recommendation category to the data recommendation equipment.
It can be understood that when the student end and the student end can communicate directly, the student end can also send the history browsing records to the student end directly. Correspondingly, after the parent terminal sets the recommendation categories, the parent terminal can also send the recommendation categories to the student terminal, and when the student terminal sends the data acquisition instruction, the recommendation categories are sent at the same time.
Optionally, in order to facilitate the parent end to quickly and accurately get familiar with knowledge points of historical browsing of students, the setting step 220 may include steps 221 to 222:
and step 221, determining the historical browsing category of the student according to the historical browsing record.
Specifically, the knowledge points corresponding to the historical teaching contents can be determined according to the knowledge points recorded by the tags of the historical teaching contents in the historical browsing records. Optionally, if different historical teaching contents correspond to the same historical browsing category, only one historical browsing category may be reserved.
Step 222, sending the historical browsing category to the control device, so that the control device sets a recommendation category according to the historical browsing category.
After the history browsing category is obtained, the history browsing category is sent to the parent terminal, and then the parent terminal can determine the recommendation category according to the history browsing category.
And step 230, storing the recommendation category sent by the control device.
And after receiving the recommendation category fed back by the home agent, saving the recommendation category so as to obtain the recommendation category when receiving the data acquisition instruction. It can be understood that after the parental side updates the recommendation categories, the data recommendation device updates the recommendation categories at the same time.
Above-mentioned, set up recommendation classification through the head of a family end, can make recommendation classification more laminate student's actual conditions, simultaneously, avoided because the student makes the condition of recommending inapplicable teaching content to the student to knowledge point distinguishability.
Fig. 2 is a flowchart of another data recommendation method according to an embodiment of the present application. At this time, the recommendation reference data includes a recommendation category, student location data, and behavior data. Referring to fig. 2, the data recommendation method specifically includes:
and 310, when a data acquisition instruction is received, acquiring a teaching content data set and recommendation reference data, wherein the recommendation reference data comprises recommendation categories, student position data and behavior data.
And 320, selecting teaching contents matched with the student position data in the teaching content data set, and forming a first data subset.
Specifically, each teaching content in the teaching content data set is traversed to find the teaching content matched with the student position data, and the matched teaching content is combined into a first data subset. When the teaching contents are matched, the position data added when the teaching contents are created can be obtained, and matching is carried out according to the position data. And determining the teaching material version according to the student position data, and further performing matching according to the teaching material version.
In the embodiment, a description is given by taking a manner of determining a teaching material version according to student position data and matching teaching contents according to the teaching material version as an example, in this case, step 320 includes steps 321 to 324:
step 321, determining teaching material information used by the student according to the student position data.
Specifically, the data recommendation device is preset with corresponding relations between different teaching material versions and use areas thereof, and when the teaching material version in a certain area is updated, the data recommendation device synchronously updates the corresponding relations. Illustratively, after the student position data is acquired, the area to which the student position data belongs is determined, then the teaching material version corresponding to the area is determined according to the pre-recorded corresponding relation, and the teaching material information is generated based on the teaching material version. It is to be understood that the division rule embodiment of the region is not limited, and for example, division is performed in units of provinces.
And 322, acquiring teaching material labels of the teaching contents in the teaching content data set.
Illustratively, the tags corresponding to the teaching contents in the teaching content data set include teaching material tags, and the teaching material tags record teaching material versions of the teaching materials used by the teaching contents. And when the teaching content data set is obtained, synchronously obtaining each teaching material label.
Step 323, searching teaching material labels matched with the teaching material information in each teaching material label.
Specifically, each teaching material label is matched with teaching material information to search for the matched teaching material label. And the teaching material version recorded by the matched teaching material label is consistent with the teaching material version in the teaching material information.
And 324, acquiring teaching contents corresponding to the matched teaching material labels, and forming a first data subset.
Specifically, according to the matched teaching material label, corresponding teaching contents are acquired in a teaching content data set, and the acquired teaching contents are combined into a data set.
