Sujith 1,2 Koforidua Polytechnic, Abstract The ineorable growth on internet in today s world has not only paved way for easy communication and sharing of data, but also created a new dimension in the research on online consumer behavior. Web mining is a prolific approach towards the study of the behavior of online consumers on real time. Web mining is an application to discover the interesting usage patterns from the web data through the web server log file. Several commercial and open source tools are used in analyzing the web log data to understand the behavior of consumers. In this research paper, some of the modern tools of web mining are analyzed based on the techniques to ascertain its efficiency and accuracy. Key words Web mining, Web usage mining, Web mining tools, Web mining techniques 1.0 Introduction A popular website states that, as of today, we have an average of 986,945,830 websites online [1]. Each day, close to 14,000 websites are launched. Hence, the World Wide Web is flooded with information. This eponential growth of websites and information has paved way for a new research called Web mining or Web usage mining. As the internet revolution has taken the world to a net stage, parallel e- commerce has also grown along with internet. Success rate of e-commerce sites like flipkart, amazon, kaymu and many more has proven that internet is an important effective tool for business [2]. Millions of users are registering in to the e-commerce sites and this has led to a tough competition among the companies. Big corporates have started funding research programmes which can help them to understand the consumer behavior. Hence, web mining is a decisive tool which is used in analyzing the log files to understand the visitor s behavior on a website. 1

2 Web mining is the etraction of interest and potential useful pattern and implicit information from artifacts or activity related to WWW [3]. The etracted information is used for personalization, profiling and future prediction. The usage data captures the identity or origin of the web users along with browsing behavior at website. Information is captured from a webserver log file. There have been various researches already done and still going on in the analysis of consumer behavior. Even though numerous mathematical techniques are used, there is no appropriate tool to fulfill all the requirements of a researcher. Some tools are performing well in some aspects of research direction but one cannot be sure it may fulfill the requirement of any researcher s complete needs. Hence, it is mandatory that a researcher should have clear knowledge about the tools available for their research domain. This research paper may be an eye opener for any interested person to know the tools which are available for the data mining research. This paper is organised as chapter I : Introduction, Chapter II :Related works, Chapter III : WebMining tools and Techniques, Chapter IV : Comparative study Chapter V : Conclusion. Web Server Log File Weblog file is a simple tet file which logs all the activities on a server. Analyzing the webserver log file is a pre-processing technique in the research of web usage mining. A server log file is automatically created in a server which consists of lists of activities performed by a visitor on a website [4]. The following are the types of information that can be retrieved from a server log file. IP Address Identity of the computer making request Login ID of the visitor Date/Time Location Status Code Size Web Page Referred Several tools are used in analyzing the log files. This paper will focus on the different types of tools and the features in each tool. 2

3 2.0 Related Research Works Several data pre-processing tools with different functionalities are released in the market. Faustina Johnson carried out a research on analyzing various techniques used for etracting information from the different types of data available in the internet and how this data could be used for mining purposes. Research also states that Semantic Web is a future vision in which web content can be manipulated by automated systems for analysis and synthesis [5]. Arun et al., eplored the web usage pattern which is a key to promoting intelligence in e-commerce. They also insisted that it ought to study the loopholes within the analysis of internet usage patterns through eisting tools and to style economical, climbable and powerful analysis tool. Santhakumar and Christopher (2015)., analyzed the web usage data by applying two different clustering algorithm such as K-means and Fuzzy C means in web usage data set using the tool Rapidminer [6]. Pierrakos et al., did an overview of KOINOTITES system that eploited Web Usage Mining techniques in order to identify communities of Web users that ehibited similar navigational behavior with respect to a particular web site [7]. 3.0 Webmining Tools and Techniques Contemporaneous researches and tools are introduced using various data mining pre-processing technique to analysis the web log files,the following are a few of those, especially with good features. 3.1 RapidMiner Rapidminer is a software developed using Java programming language. It provides data mining and machine learning procedures including: data loading and transformation, data pre-processing and visualization, predictive analysis and statistical modeling, evaluation and deployment [8]. Rapidminer is a cross platform software which can be deployed in any operating system. Software allows direct importing on the weblog files and it supports the following tasks: Aggregations of web usage statistics Automated web page visitor session etraction Search robot filtering 3

4 Mash-ups with web services to map ip addresses to countries, cities, and map coordinates 2D and 3D visualization of web usage statistics and many more. Rapidminer is comparatively faster than most of the data mining tools available in the market. Due to the GUI interface and the various formats of reports available in the market, it s one of the preferred solutions for many analysts. 3.2 Weblog Epert Weblog epert is an Apache and IIS log analyzing software which will give information about a site s visitors. It can work only on Windows Operating System and has very limited functionalities compared to other data mining tools. Weblog eperts can also read the compressed files like GZ, ZIP [9]. Weblog eperts can generate the reports with following details: Activity statistics Access Files and paths Referred Pages 3.3 W3Perl W3Perl is a logfile analyser based on logfiles parsing and distributed under the GPL licence. It requires a configuration file which can be built from a web interface. It s a platform independent tool which will support different platforms. It s a free log file analyzing software building using Perl and this can be deployed in any operating system which supports Perl. W3Perl can analyze Web/FTP/Mail/CUPS/DHCP/SSH and Squid log files. Reports can be generated in the various formats like HTML or Table manner. If there is any access restriction to the log files, W2Perl can be used with a small piece of JavaScript code and can be monitored. In such cases, the script will create the log files. The main features are: Reports generation Multi-language output Support for load balancing 4

5 3.4 Webalizer This software is used to analyze the web and usage logs in the server. Webalizer is mostly used to analyze the web traffic using the URL, Hit, Page, File, Visitor, Host and User Agent. Upon analyzing the server log files, the following information is etracted to generate the report. Client s IP Address URL Paths Processing Time User Agent Referrer With additional features These etracted information are generally grouped and displayed in an HTML format. Apart from the HTML files, normal tet file reports are also generated which can later be imported into spreadsheet manually. The major limitation of webalizer is that, it cannot differentiate between a web robot and human visitor. 3.5 Alterwind Log Analyzer It s a weblog analysis tool which will provide statistics based on the web usage.
