[0002] Since 2012, distance learning, such as online video learning, has become increasingly popular. However, due to the lack of in-person teacher interaction, teachers are unable to assess students' progress. Students may also struggle to consolidate their learning due to their lack of independent learning skills. For example, some English learning software currently highlights important words in a text, but due to the shortcomings of online learning, teachers are unable to provide individualized reinforcement learning for each student. Therefore, a reinforcement learning method is needed that can save the course context where the knowledge points are located, allowing for the option to jump back and restore them later during review. This method can connect concepts of similar nature and provide options for context selection. This method can help learners build connections and relationships between knowledge points in their minds, strengthening their memory and consolidating their learning. Summary of the Invention

[0026] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in describing the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0027] Figure 1 Flowchart of an online multi-scenario reinforcement learning method.

[0028] Figure 2 This is a flowchart of the steps for obtaining the named entities in S2 in an online multi-scenario reinforcement learning method. DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figures 1 to 2 As shown, an online multi-scenario reinforcement learning method includes at least the following steps:

[0032] S1, identifying text data in the current online teaching video frame through the OCR algorithm, and obtaining knowledge points based on the text data analysis.

[0033] Furthermore, text recognition is performed on the current online teaching video frame to capture text information contained in the current online teaching video frame.

[0034] S2, obtaining named entities that may become knowledge points through entity recognition technology, and obtaining target knowledge points based on the named entities; knowledge points are teaching knowledge points extracted from text content or image content contained in the current teaching video.

[0035] The step of obtaining the named entity in S2 includes:

[0036] S2.1, extracting character information from the text information.

[0037] S2.2, perform entity location, entity segmentation and implementation extraction based on the character information to obtain the named entity that may become a knowledge point.

[0038] The entity type of the named entity is obtained based on semantic analysis, and the named entity is classified into a corresponding entity type, for example, entity types include person, organization, location, time expression, quantity, currency value, percentage, etc.

[0039] Entity information of the named entity is extracted, and based on the entity information, whether historical review content already exists in the named entity is determined; if it is determined that the historical review content already exists, it is marked as a knowledge point named entity.

[0040] The learning course library is queried, all the historical review contents are associated with the knowledge point naming entity, and all the historical review contents are obtained for association.

[0041] Obtain the learner's ID information, obtain the completed course information based on the ID information, and remove the mastered knowledge point named entities from the completed course information to obtain a simplified knowledge point named entity. If the mastered knowledge point named entity is not included in the completed course information, the knowledge point named entity is the simplified knowledge point named entity.

[0042] The simplified knowledge point named entity is highlighted, and the target knowledge point named entity is obtained. The simplified knowledge point named entity is the knowledge point that needs to be reviewed obtained by machine calculation and analysis, and the target knowledge point named entity is the knowledge point that the learner actively selects to review.

[0043] S3, the target knowledge point is subject to entity recognition, target review content is matched for the target knowledge point and the target knowledge point is marked; the target knowledge point on any web page on any platform that has been saved by the learner is marked and highlighted.

[0044] The target review content includes historical learning text information, the address of the historical learning text, and historical learning records that are essentially the same as the target knowledge point;

[0045] The historical learning records include the historical learning time, historical learning frequency, and historical learning time. Later, the historical learning records can be used to further optimize review guidance. For example, in different scenarios with the same amount of text or in the same scenario, the historical learning time of the same knowledge point can be compared twice. If the learning time decreases significantly, it is considered that the knowledge point has been mastered. Later, the simplified knowledge point named entities can be further simplified.

[0046] S4, performing entity alignment on the target knowledge point and the corresponding target review content to obtain the target review content that is essentially the same as the target knowledge point content;

[0047] S5, recording the link of the scene where the corresponding target review content is located and building an association link between the knowledge and the target knowledge point.

[0048] The step S5 includes establishing a jump channel, wherein the jump channel includes a plurality of target review content options.

[0049] The technical solution of this application can save the course scenes where the knowledge points are located, and can be selected to jump and restore during later review. It can connect concepts of the same nature and provide them for selection in the scene selection. It can promote learners to build the context and connection between knowledge in their minds, strengthen memory, and consolidate learning.

[0050] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art based on the technical guidance of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
