Application of Fuzzy Logic for User Classification in Personalized Web Search

Sendhilkumar S, Selvakumar K, Mahalakshmi G.S
2014 International Journal on Cybernetics & Informatics  
This work proposes a fuzzy based user classification model to suit a personalised web search environment.  ...  This fluctuating nature of user behaviour and user interest shall be well interpreted within a fuzzy setting. Prior to analysing user behaviour, nature of user interests has to be collected.  ...  A recommendation system based on fuzzy linguistic modelling has this approach as its core.  ...

Active Fuzzy Weighting Ensemble for Dealing with Concept Drift

Fan Dong, Jie Lu, Guangquan Zhang, Kan Li
2018 International Journal of Computational Intelligence Systems  
Once a drift is confirmed, it uses data instances accumulated by the drift detection method to create a new base classifier.  ...  Then, it applies fuzzy instance weighting and a dynamic voting strategy to organize all the existing base classifiers to construct an ensemble learning model.  ...  Data in non-stationary environments always involves concept drift and is a very pervasive phenomenon in real-world applications, such as changes in user interest in recommender systems, the emergence of  ...
