Methods and systems for utilizing content, dynamic patterns, and/or relational information for data analysis
View Patent ↗The present invention is directed generally to providing systems and methods for data analysis. More specifically, embodiments may provide system(s) and method(s) including dynamic user modeling techniques to capture the relational and dynamic patterns of information content and/or users' or entities' interests. Various embodiments may include system(s) and method(s) that are based on, for example, the past history of content semantics, temporal changes, and/or user community relationship. Various embodiments may include modeling and/or analysis of the dynamic nature of an item of interest's value to a user(s)/entity(ies) over time. The dynamic factors may be consider in any manner, such as, individually or combined, sequentially or simultaneously, etc. Further, some embodiments may include, for example, system(s) and method(s) relating to analyzing data to capture user/entity interests and/or characteristics, consider content semantics and evolutionary information, and/or using community relationships of users/entities to thereby analyze information and provide dynamic conclusion(s) (e.g., recommendation(s)).
1. A method of data analysis, comprising:
determining with a processor dynamic patterns over time of user characteristics;
determining with a processor dynamic patterns over time of information of interest to users; and
generating with a processor predictions or recommendations based on users' dynamic pattern variations and documents' dynamic patterns.
2. The method of claim 1 , wherein the dynamic patterns over time of user characteristics includes user intention and change in user interest.
3. The method of claim 1 , wherein dynamic patterns over time of information of interest to users includes long-term information and short-term information grouping and information expiration date prediction.
4. The method of claim 3 , wherein the long-term information or the short-term information item is a document.
5. The method of claim 1 , further comprising the step of creating formal communities of users and/or informal communities of users using time as a factor.
6. The method of claim 5 , wherein a content-time-community model creates the informal communities.
7. The method of claim 1 , further comprising the step of providing an adaptive user model to generate the predictions or recommendations.
8. The method of claim 7 , wherein the adaptive user model is a stage-wise estimation procedure for fitting an additive logistic regression model by minimizing a loss function.
9. The method of claim 7 , wherein the adaptive user model is a time-sensitive Adaboost procedure.
10. A data analysis system, comprising:
a memory;
a processor configured to:
determine dynamic patterns over time of user characteristics;
determine dynamic patterns over time of information of interest to users; and
generate predictions or recommendations based on users' dynamic pattern variations and documents' dynamic patterns.
11. The system of claim 1 , wherein the dynamic patterns over time of user characteristics includes user intention and change in user interest.
12. The system of claim 1 , wherein dynamic patterns over time of information of interest to users includes long-term information and short-term information grouping and information expiration date prediction.
13. The system of claim 12 , wherein the long-term information or the short-term information item is a document.
14. The system of claim 10 , further comprising means for creating formal communities of users and/or informal communities of users using time as a factor.
15. The system of claim 14 , wherein a content-time-community model creates the informal communities.
16. The system of claim 10 , further comprising means for providing an adaptive user model to generate the predictions or recommendations.
17. The system of claim 16 , wherein the adaptive user model is a stage-wise estimation procedure for fitting an additive logistic regression model by minimizing a loss function.
18. The system of claim 16 , wherein the adaptive user model is a time-sensitive Adaboost procedure.
