It provides abundance information for the internet users. The growth of web is tremendous as approximately one million pages are added daily. Users' accesses are recorded in web logs.Because of the tremendous usage of web, the web log files are growing at a faster rate and the size is becoming huge. Web data mining is the application of data mining techniques in web data. Extraction of user behavior is an important work in web mining. Web Usage min ing applies mining techniques in log data to extract the behavior of users which is used in various applications like personalized services, adaptive web sites, customer profiling , prefetching, creating attractive web sites etc., preprocessing, pattern d iscovery and pattern analysis. Web log data is usually noisy and ambiguous and preprocessing is an important process before mining. For efficient mining process the transactions are to be constructed accurately which is an important task of preprocessing. This paper describes about the accomplishment of path completion, finding content path set, and travel path set which shows user interest.

user navigation patterns which are useful for classification system to classify a new user with the previous users group.
Methodology: Three real time web log data sets are collected from e-commerce web server, academic institution web
server and a research journal web server. All three sets were collected from IIS web servers. After navigation patterns are
derived from preprocessing step it is clustered into groups by using traditional Fuzzy C-Means technique. The clusters are
validated and re-clustered using Bolzano_Weierstrass Theorem. Findings: Web log data is preprocessed and ICA is applied
in the user session matrix to select relevant and important features. To measure the clustering accuracy of proposed
and the existing methods, the parameters such as Rand Index, F measure are calculated and compared. It shows proposed
BWFCM have higher rand index rate than FCM and lesser error rate. To understand the impact of the feature selection
method, the data sets were implemented with the existing and proposed methods of feature selection. The parameters
taken for comparison were Rand Index, Sum of Squared Errors, F-measure. The method was implemented in all the three
data sets after data cleaning, session construction step. Clustering was carried out twice with the proposed clustering algorithm
in all the three data sets, without selecting features and after selecting features. It was observed that the clustering
results are poor when applied in full data set with irrelevant features, and the performance was increased after relevant
features were selected. Conclusion: The result of the optimized clustering proves its significance and there is an increase
in similarity of intra clustering and dissimilarity in inter clustering than the existing methods.

technological up gradation, the datasets which are large are distributed over different locations and
classification has become a difficult task. The single classifier models are not sufficient for these types of
datasets. So the recent research concentrates on combination of various classifiers and creates models.
Ensemble methods combine multiple models and are useful in both supervised and unsupervised learning.
This paper discusses the framework of ensemble and two types of ensemble models. A review of various
algorithms of these two models is given. Combination methods which are used for combining outputs and few
applications where it can be used effectively are also discussed.

of applications like Web analysis, CRM, marketing, medical diagnostics, computational biology, and many others. Clustering is the grouping of similar instances or objects. The key factor for clustering is some sort of measure that can determine whether two objects are similar or dissimilar. In this paper a novel clustering method to partition user sessions into accurate clusters is discussed. The accuracy and various performance measures of the proposed algorithm shows that the proposed method is a better method for web log mining.
