RecB: Set Theory based Technique for Large Scale Pattern Mining in Web Logs

Tanya Steen, Ray Lindsay
2015 International Journal of Computer Applications  
This paper stresses the importance of data preprocessing and introduces an efficient method for mining patterns in large sized collections of web logs (of all types) based on classic set theory properties  ...  Another challenge is that many proposed pattern mining techniques are usually tested on small benchmark datasets, so their performance on a large scale is hard to predict.  ...  This paper describes some properties of set theory applied to web usage mining and offers a method for pattern identification in weblog data.  ...
