Step 1, performing behavior habit mining on the metauniverse user activity big data to obtain a corresponding conversation behavior habit vector.
Wherein, the conversation behavior habit vector (which can be understood as behavior habit features in a global scenario) contains user preferences (which can be understood as behavior preferences of a user in a process of metaspace interaction) of each activity event information (such as a user behavior event) in the metaspace user activity big data (such as a user interaction activity record in a virtual mall). Furthermore, behavioral habit mining can be understood as feature extraction.
And 2, determining visual windows corresponding to at least one user operation track in the metauniverse user activity big data respectively, and utilizing the determined at least one visual window to disassemble the conversation behavior habit vector to obtain stage behavior habit vectors corresponding to the at least one visual window respectively.
For example, the user operation trajectory may be used to record some columns or consecutive operation behavior data of the user, and the corresponding visualization window may highlight the user operation trajectory, so that the session behavior habit vector may be split to obtain the local stage behavior habit vector.
And 3, combining the user preference items of the activity event information and the first correlation scores among the user preference items to obtain corresponding service demand prediction knowledge.
For example, a relevance score may be understood as a degree of association or a degree of relevance, and a relevance score may be a pearson relevance coefficient. Further, the service demand forecasting knowledge can focus on transition and forecasting from the behavior preference dimension to the user demand dimension, and the obtained service demand forecasting knowledge can reflect feature knowledge (feature vector) of the attention level of the user demand from the overall level.
And 4, combining the service demand forecasting knowledge and at least one stage behavior habit vector and a second correlation score between the service demand forecasting knowledge and the at least one stage behavior habit vector to obtain a corresponding target conversation behavior habit vector and at least one target stage behavior habit vector.
The target session behavior habit vector and the target stage behavior habit vector can reflect the characteristic vector of the behavior habit hiding the user requirement from the global level and the local level respectively, and therefore the target session behavior habit vector and the target stage behavior habit vector can be used as raw materials for user requirement theme mining.
And 5, combining the target conversation behavior habit vector and the at least one target stage behavior habit vector to obtain a user demand theme corresponding to the metauniverse user activity big data.
In the embodiment of the invention, the user requirement theme can be the category of the user requirement corresponding to the metauniverse user activity big data, such as 'identity privacy security', 'virtual commodity pushing', 'scene rendering optimization', and the like.
It can be understood that, when the method is applied to the steps 1 to 5, the conversation scene and the conversation link of the metauniverse user activity big data are associated by predicting the requirements of the conversation behavior habit vector and the stage behavior habit vector after the conversation behavior habit vector and the stage behavior habit vector of the metauniverse user activity big data are obtained, so that the user requirement theme which is as accurate and credible as possible can be obtained when the metauniverse user activity big data are subjected to requirement theme mining based on the obtained target conversation behavior habit vector and the target stage behavior habit vector, and the quality of the user requirement mining on the metauniverse user activity big data is improved.

By the design, the corresponding service demand prediction knowledge can be accurately and completely obtained.
Under other possible design considerations, the step 4 of obtaining the corresponding target session behavior habit vector and at least one target phase behavior habit vector by combining the service demand forecasting knowledge and at least one phase behavior habit vector and the second correlation score between the service demand forecasting knowledge and the at least one phase behavior habit vector may include the following steps: for at least one phase behavior habit vector, the following steps are carried out: based on a set AI rule, performing correlation scoring operation on user preference items of each activity event information in a stage behavior habit vector and activity demand knowledge of each activity event information in the service demand forecasting knowledge respectively to obtain a second correlation score between the stage behavior habit vector and the service demand forecasting knowledge; and integrating the service demand forecasting knowledge and the at least one stage behavior habit vector respectively according to the second relevance scores to obtain a corresponding target conversation behavior habit vector and at least one target stage behavior habit vector. Therefore, the target conversation behavior habit vector and the target stage behavior habit vector which carry hidden demand details can be focused on based on the attention rules, and a credible basis is provided for subsequent user demand topic mining.
In some possible embodiments, the obtaining, by combining the target session behavior habit vector and the at least one target phase behavior habit vector, the user requirement theme corresponding to the metauniverse user activity big data, which is described in step 5, may include the technical solutions described in step 51 and step 52.

And step 52, obtaining a user requirement theme corresponding to the meta universe user activity big data according to the scene requirement keyword and each link requirement keyword.
It will be appreciated that, as applied to steps 51 and 52, different ranges of requirement keywords can be considered, thereby ensuring the suitability of the resulting user requirement topic.
In some possible embodiments, the determining, by the requirement topic mining network described in step 51, a scene requirement keyword corresponding to the target session behavior habit vector and a link requirement keyword corresponding to the at least one target stage behavior habit vector respectively may include the technical solutions described in step 511 and step 512.

And step 512, inputting the at least one target stage behavior habit vector into the requirement topic mining network respectively, obtaining second hit indexes of the at least one target stage behavior habit vector corresponding to each preset user requirement item respectively, and taking the second hit indexes as link requirement keywords.
By way of example, the hit index may be understood as a probability value or a confidence score. In this way, based on steps 511 and 512, the link requirement keyword can be determined based on the hit index, thereby improving the accuracy and efficiency of determining the link requirement keyword.
In some examples, the obtaining of the user requirement theme corresponding to the meta universe user activity big data according to the scene requirement keyword and the link requirement keywords, which is described in step 52, may include the following: for each preset user requirement item, the following steps are implemented: according to the second hit indexes of the at least one target stage behavior habit vector, which belong to a preset user requirement item, averaging the first hit indexes corresponding to the preset user requirement item and the second hit indexes meeting the preset judgment requirement, and determining the target hit index corresponding to the preset user requirement item; and according to the target hit indexes corresponding to the preset user requirement items, taking the preset user requirement items with the target hit indexes larger than a preset limit value as user requirement themes corresponding to the metauniverse user activity big data. By the design, the precision of the determined user demand theme can be guaranteed by carrying out quantitative judgment based on the hit index, and the scene adaptability of the user demand theme can be guaranteed by carrying out analysis based on the preset user demand item.
