The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It is to be noted that the terms "comprises" and "comprising" and any variations thereof in the embodiments and drawings of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
The embodiment of the invention discloses a dictation content recommendation method based on a knowledge graph and electronic equipment, which can automatically summarize dictation contents for student users and improve intelligence. The following are detailed below.
Example one
Referring to fig. 1, fig. 1 is a schematic flowchart of a method for recommending dictation content based on a knowledge graph according to an embodiment of the present invention. The method for recommending dictation contents based on knowledge graph shown in fig. 1 can be applied to various electronic devices such as tablet computers, personal computers, learning tablet computers, Mobile phones, family education devices (such as family education machines), smart watches (such as telephone watches), multimedia teaching devices, Mobile Internet Devices (MID) and the like. As shown in fig. 1, the method for recommending dictation content based on knowledge-graph may include the following steps:
101. after the dictation application finishes playing any pronunciation segment corresponding to the dictation content, the electronic equipment acquires the actual writing content written by the student user according to the pronunciation segment.
As an optional implementation manner, in the embodiment of the present invention, after the dictation application finishes playing any one of the sound clips corresponding to the dictation content, the electronic device may control the dictation application to pause playing the sound clip corresponding to the next dictation content, and the electronic device may obtain, through a camera module (also referred to as a camera) disposed on the electronic device, actual writing content written by the student user according to the sound clip; or, the electronic device may acquire the actual writing content written by the student user according to the reading clip through a camera module (e.g., a camera module set on a smart watch worn by the student user) externally connected to the electronic device in a wired or wireless manner. For example, the left wrist of the student user can wear a smart watch, and the right palm holds a handwriting pen to perform listening and writing on the exercise book; the intelligent watch can be in communication connection with the electronic equipment in a wireless mode (such as Bluetooth or Wi-Fi), after the dictation application finishes playing any pronunciation section corresponding to the dictation content, the electronic equipment can control the dictation application to pause playing the pronunciation section corresponding to the next dictation content, and the electronic equipment can acquire the actual writing content written by the student user according to the pronunciation section through a camera module arranged on the intelligent watch worn on the left wrist of the student user. This way, the power consumption of the electronic device when dictating the student user can be reduced.
As another optional implementation manner, in the embodiment of the present invention, after the dictation application finishes playing any sound reading segment corresponding to the dictation content, the electronic device may first obtain the dictation expression of the student user (for example, obtain the dictation expression of the student user through a shooting module set on an intelligent watch worn by the student user), further, the electronic device may check whether the dictation expression of the student user matches a preset specified expression for triggering obtaining an actual writing content written by the student user, and if the specified expression matches the preset specified expression, obtain the actual writing content written by the student user according to the sound reading segment through the intelligent watch worn by the student user.
Further, if it is checked that the dictation expression of the student user is not matched with the preset specified expression for triggering to acquire the actual writing content written by the student user, the electronic equipment can also check whether the dictation action of the student user is matched with the preset specified action for triggering to acquire the actual writing content written by the student user, and if the dictation action is matched with the preset specified action for triggering to acquire the actual writing content written by the student user, the electronic equipment acquires the actual writing content written by the student user according to the reading segment through the intelligent watch worn by the student user. On the contrary, if the dictation action of the student user is verified to be not matched with the preset specified action for triggering the acquisition of the actual writing content written by the student user, the electronic equipment can control the dictation application to continuously play the pronunciation section corresponding to the next dictation content.
102. The electronic equipment compares the actual written content with any dictation content to determine whether any dictation content belongs to the stubborn dictation content of the student user.
As an optional implementation manner, in an embodiment of the present invention, the comparing, by the electronic device, the actual written content with the any dictation content to determine whether the any dictation content belongs to the stubborn dictation content of the student user may include:
the electronic equipment compares the actual writing content with any dictation content, and if the actual writing content is different from any dictation content, the electronic equipment determines that any dictation content belongs to the difficult dictation content of the student user;
if the actual writing content is the same as any dictation content, acquiring the writing duration which is recorded in advance when the student user writes the actual writing content according to the pronunciation segment, wherein the writing duration at least comprises the writing duration of each character included in the actual writing content;
aiming at any character included in the actual written content, judging whether the character writing duration of the any character exceeds the single character writing duration specified by a preset model, and if so, determining that any dictation content belongs to the difficult dictation content of the student user; if not, determining that any dictation content does not belong to the difficult dictation content of the student user.
For example, after the dictation application finishes playing any one of the sound segments corresponding to the dictation contents "gentle" such as the standard mandarin sound of the "gentle" two-character, the electronic device may control the dictation application to pause to continue playing the sound segment corresponding to the next dictation content, and record in advance the actual writing contents "gentle" written by the student user according to the sound segment corresponding to the any one of the dictation contents "gentle" and the writing duration when the actual writing contents "gentle" are written, where the writing duration at least includes the writing duration (e.g., 10s) of the "warm" character and the writing duration (e.g., 8s) of the "soft" character included in the actual writing contents "gentle".
As an optional implementation manner, in the embodiment of the present invention, after the dictation application finishes playing any reading segment corresponding to the "gentle" dictation content (e.g. the standard mandarin chinese reading of the "gentle" two-character), the shooting module arranged in the electronic equipment or the shooting module connected with the electronic equipment externally (such as the shooting module on the intelligent watch worn by the student) can be used for shooting the video clip of the actual writing content written by the student according to the reading clip corresponding to any dictation content, identifying and recording the writing duration of the actual writing content from the video clip, the writing time period includes at least a writing time period of each word included in the actual written contents, for example, a writing time period (e.g., 10s) of a "warm" word included in the actual written contents "gentle" and a writing time period (e.g., 8s) of a "gentle" word.
As an optional implementation manner, in the embodiment of the present invention, for any word included in the actual written content, determining whether a word writing duration of the any word exceeds a single word writing duration specified by a preset model, includes:
aiming at any character included in the actual written content, determining the single character writing duration which is specified by a preset model and is in direct proportion to the total stroke number of the any character;
and judging whether the character writing duration of any character exceeds the single character writing duration in direct proportion to the total stroke number of any character.
For example, the electronic device may determine, for any word "warm" included in the actual written content "soft", that the writing duration of a single word specified by the preset model and in direct proportion to the total number of strokes "12" of the any word "warm" is "6 s";
and the electronic equipment can judge that the writing duration of the character of any character 'warm' is longer than the writing duration of the single character '6 s' in direct proportion to the total stroke number '12' of any character 'warm', and at the moment, the electronic equipment can determine that any dictation content 'warm and soft' belongs to the difficult dictation content of the student user.
As an alternative implementation manner, in the embodiment of the present invention, the pre-recorded writing duration of the student user writing the actual writing content according to the pronunciation segment may include a word interval writing duration between every two adjacent words, in addition to the word writing duration of each word. Correspondingly, when the writing duration of any character is judged not to exceed the single character writing duration in direct proportion to the total stroke number of the any character, the electronic equipment can judge whether the character interval writing duration between any two adjacent characters included in the actual writing content exceeds the character interval preset writing duration specified by the preset model, and if so, the electronic equipment can determine that any dictation content is 'soft and warm' and belongs to the difficult dictation content of the student user; if not, the electronic equipment can determine that any dictation content is not the difficult dictation content of the student user, namely the 'soft' dictation content.
103. If any dictation content belongs to the stubborn dictation content of the student user, the electronic equipment determines a target node from all knowledge nodes of a preset knowledge graph; wherein the any dictation content is associated with the target node.
In the embodiment of the present invention, a knowledge graph composed of knowledge nodes may be preset on the electronic device, each knowledge node may be a certain chapter, and any dictation content associated with a target node may be understood as a content of the any dictation content belonging to the target node (e.g., a certain chapter).
104. The electronic equipment summarizes the dictation content of the student user from other contents except any dictation content in the contents associated with the target node.
By implementing the method described in fig. 1, dictation contents can be automatically collected for student users, so that intelligence is improved; in addition, the implementation of the method described in fig. 1 is beneficial to improving the mastery degree of the student user on the content of the knowledge node associated with the stubborn dictation content.
Example two
Referring to fig. 2, fig. 2 is a schematic flowchart of another knowledge-graph-based dictation content recommendation method according to an embodiment of the present invention. The dictation content recommendation method based on the knowledge graph shown in fig. 2 can be applied to various electronic devices such as tablet computers, personal computers, learning tablet computers, mobile phones, home education devices (such as a home education machine), smart watches (such as a telephone watch), multimedia teaching devices, and MID. As shown in fig. 2, the method for recommending dictation content based on knowledge-graph may include the following steps:
201. after the dictation application finishes playing any pronunciation segment corresponding to the dictation content, the electronic equipment acquires the actual writing content written by the student user according to the pronunciation segment.
202. The electronic equipment compares the actual written content with any dictation content to determine whether any dictation content belongs to the stubborn dictation content of the student user.
203. If any dictation content belongs to the stubborn dictation content of the student user, the electronic equipment determines a target node from all knowledge nodes of a preset knowledge graph; wherein the any dictation content is associated with the target node.
204. The electronic equipment summarizes the dictation content of the student user from other contents except any dictation content in the contents associated with the target node.
205. The electronic equipment takes account information of the student user logging in the dictation application as the identity of the student user, and inquires the identity information of the teacher equipment corresponding to the identity of the student user.
The teacher device may be a teacher device for a teacher who is responsible for teaching the subject (e.g., language) to which the dictation content belongs to the student user.
206. The electronic device reports a dictation plan including the identity of the student user and the node ID of the target node to the teacher device based on the identification information of the teacher device.
By implementing the steps 205 to 206, the teacher can timely learn the knowledge nodes of the problematic dictation contents of the students, so that the teacher can adjust the dictation plan in a targeted manner.
As an optional implementation manner, in this embodiment of the present invention, after the electronic device performs step 206, the following operations may also be performed:
the electronic equipment receives appointed dictation contents pushed by the teacher equipment for the student user, wherein the appointed dictation contents are dictated by the teacher according to the identity of the student user, then the teacher judges that the learning progress of the student user is matched with the contents associated with the target node (namely, the contents associated with the target node are understood to be learned by the student user), and the dictated contents are appointed for the student user from the contents associated with the target node;
and the electronic equipment updates the summarized dictation contents of the student user according to the appointed dictation contents pushed by the teacher equipment for the student user.
After the teacher can determine the learning progress of each student user according to the identity of each student user, different amounts of dictation contents specified for each student user from the contents associated with the target node can be obtained, and therefore the purpose of personalized dictation capacity exercise can be achieved.
As a further alternative, in the embodiment of the present invention, if the teacher determines that the learning progress of the student user does not match the content associated with the target node (i.e. it can be understood that the student user has not learned the content associated with the target node yet), the teacher may determine another node from the knowledge nodes of the preset knowledge graph, where the learning progress of the student user matches the content associated with the another node (i.e. it can be understood that the student user has learned the content associated with the another node), and specify dictation content for the student user from the content associated with the another node, so that the electronic device may update the summarized dictation content for the student user according to the specified dictation content pushed by the teacher device for the student user. Therefore, the learned node content can be tamped by improving the mastery degree of the student user on the learned node content.
By implementing the method described in fig. 2, dictation contents can be automatically collected for student users, so that intelligence is improved; in addition, the implementation of the method described in fig. 2 is beneficial to improving the mastery degree of the student user on the content of the knowledge node associated with the stubborn dictation content.
