3. Web Mining – The Idea
In recent years the growth of the World Wide
Web exceeded all expectations. Today there
are several billions of HTML documents,
pictures and other multimedia files available
via internet and the number is still rising. But
considering the impressive variety of the web,
retrieving interesting content has become a
very difficult task.
Presented by: Anushri Gupta
4. Web Mining
Web is the single largest data source in the
world
Due to heterogeneity and lack of structure of
web data, mining is a challenging task
Multidisciplinary field:
data mining, machine learning, natural language
processing, statistics, databases, information
retrieval, multimedia, etc.

5. Opportunities and Challenges
Web offers an unprecedented opportunity and challenge to
data mining
The amount of information on the Web is huge, and easily accessible.
The coverage of Web information is very wide and diverse. One can
find information about almost anything.
Information/data of almost all types exist on the Web, e.g., structured
tables, texts, multimedia data, etc.
Much of the Web information is semi-structured due to the nested
structure of HTML code.
Much of the Web information is linked. There are hyperlinks among
pages within a site, and across different sites.
Much of the Web information is redundant. The same piece of
information or its variants may appear in many pages.

6. Opportunities and Challenges
The Web is noisy. A Web page typically contains a mixture of many
kinds of information, e.g., main contents, advertisements, navigation
panels, copyright notices, etc.
The Web is also about services. Many Web sites and pages enable
people to perform operations with input parameters, i.e., they provide
services.
The Web is dynamic. Information on the Web changes constantly.
Keeping up with the changes and monitoring the changes are
important issues.
Above all, the Web is a virtual society. It is not only about data,
information and services, but also about interactions among people,
organizations and automatic systems, i.e., communities.

Web Page Content Mining
Mines the contents of documents directly
Search Engine Mining
Improves on the content search of other tools like search
engines.
25. Web Content Mining
Web content mining is related to data mining
and text mining. [Bing Liu. 2005]
It is related to data mining because many data
mining techniques can be applied in Web content
mining.
It is related to text mining because much of the
web contents are texts.
Web data are mainly semi-structured and/or
unstructured, while data mining is structured and
text is unstructured.
26. Tech for Web Content Mining
Classifications
Clustering
Association
27. Document Classification
Supervised Learning
Supervised learning is a ‘machine learning’ technique for creating a
function from training data .
Documents are categorized
The output can predict a class label of the input object (called
classification).
Techniques used are
Nearest Neighbor Classifier
Feature Selection
Decision Tree
28. Feature Selection
Removes terms in the training documents which are
statistically uncorrelated with the class labels
Simple heuristics
Stop words like “a”, “an”, “the” etc.
Empirically chosen thresholds for ignoring “too
frequent” or “too rare” terms
Discard “too frequent” and “too rare terms”
29. Document Clustering
Unsupervised Learning : a data set of input objects is gathered
Goal : Evolve measures of similarity to cluster a collection of
documents/terms into groups within which similarity within a cluster
is larger than across clusters.
Hypothesis : Given a `suitable„ clustering of a collection, if the user is
interested in document/term d/t, he is likely to be interested in other
members of the cluster to which d/t belongs.
Hierarchical
Bottom-Up
Top-Down
Partitional
30. Semi-Supervised Learning
A collection of documents is available
A subset of the collection has known labels
Goal: to label the rest of the collection.
Approach
Train a supervised learner using the labeled subset.
Apply the trained learner on the remaining documents.
Idea
Harness information in the labeled subset to enable
better learning.
Also, check the collection for emergence of new topics

Sources
- Server access logs
- Server Referrer logs
- Agent logs
- Client-side cookies
- User profiles
- Search engine logs
- Database logs

40. Web Usage Data Preprocessing
DATA CLEANING
- Clean/Filter raw data to eliminate redundancy
LOGICAL CLUSTERS
- Notion of Single User Transaction
41. There are a variety of files accessed as a result of a request by a
client to view a particular Web page.
These include image, sound and video files, executable cgi files ,
coordinates of clickable regions in image map files and HTML files.
Thus the server logs contain many entries that are redundant or
irrelevant for the data mining tasks
Data Cleaning
Page1.html
a.gif
b.gif
User Request : Page1.html
Browser Request : Page1.html, a.gif, b.gif
3 Entries for same user request in the Server Log,
hence redundancy.
42. Hostname Date : Time Request
SOLUTION
Data Cleaning cont…
All the log entries with filename suffixes such as, gif, jpeg, GIF, JPEG, JPG
and map are removed from the log.
43. Logical Clusters
Representation of a Single User Transaction.
One of the significant factors which distinguish Web mining from other
data mining activities is the method used for identifying user transactions
The clustering is based on comparing pairs of log entries and
determining the similarity between them by means of some kind of
distance measure.
Entries that are sufficiently close are grouped together
PROBLEMS:
To determine an appropriate set of attributes to cluster.
To determine an appropriate distance metrics for them.
44. Time Dimension for clustering the log entries
Logical Clusters
Let L be a set of server access log entries
A log entry l Є L includes -
the client IP address l.ip,
the client user id l.uid,
the URL of the accessed page l.url and
the time of access l.time
Δt = Time Gap
l1.time – l2.time < = tΔ
47. Association Rules
X == > Y (support, confidence)
60% of clients who accessed /products/, also accessed
/products/software/webminer.htm.
30% of clients who accessed /special-offer.html, placed an online
order in /products/software/.
49. Mining Sequential Patterns
Support for a pattern now depends on the ordering of the items,
which was not true for association rules.
For example: a transaction consisting of URLs ABCD in that
order contains BC as an subsequence, but does not contain CB
60% of clients who placed an online order for WEBMINER,
placed another online order for software within 15 days
50. Clustering & Classification
clients who often access /products/software/webminer.html
tend to be from educational institutions.
clients who placed an online order for software tend to be
students in the 20-25 age group and live in the United States.
75% of clients who download software from
/products/software/demos/ visit between 7:00 and 11:00 pm on
weekends.

Visual Web Mining
52. Abstract
Analysis of web site usage data involves two significant challenges
Volume of data
Structural complexity of web sites
Visual Web Mining
Apply Data Mining and Information Visualization techniques to web domain
Aim : To correlate the outcomes of mining Web Usage Logs and the extracted
Web Structure, by visually superimposing the results.
53. Terminology
Information Visualization
use of computer-supported, interactive,visual representations of abstract data
to amply cognition
User Session
compact sequence of web accesses by a user
Visual Web Mining
- application of Information Visualization techniques on results of Web Mining
- to further amplify the perception of extracted patterns, rules and regularities
54. provides a prototype implementation for applying information
visualization techniques to the results of Data Mining.
Visualization to obtain :
- understanding of the structure of a particular website
- web surfers‟ behavior when visiting that site
Due to the large dataset and the structural complexity of the sites, 3D
visual representations used.
Implemented using an open source toolkit called the Visualization
ToolKit (VTK).
Visual Web Mining Framework
56. Visual Web Mining Architecture
Input : web pages and web server log files
A web robot (webbot) is used to retrieve the pages of the website.
In parallel, Web Server Log files are downloaded and processed through
a sessionizer and a LOGML file is generated.
The Integration Engine is a suite of programs for data preparation,
i.e., cleaning, transforming and integrating data.
57. Visual Web Mining Architecture
The Visualization Stage : maps the extracted data and attributes into
visual images, realized through VTK extended with support for graphs.
VTK : set of C++ class libraries accessible through
- linkage with a C++ program, or
- via wrappings supported for scripting languages (Tcl, Python or Java),
here tcl script used.
Result : interactive 3D/2D visualizations which could be used by analysts
to compare actual web surfing patterns to expected patterns
58. Results
VWM provides an insight into specific, focused, questions that form a
bridge between high-level domain concerns and the raw data :
What is the typical behavior of a user entering our website?
What is the typical behavior of a user entering our website in page A from
„Discounted Book Sales‟ link on a referrer web page B of another web
site?
What is the typical behavior of a logged in registered user from Europe
entering page C from link named “Add Gift Certificate” on page A?
59. Visual Representation
analogy between the „flow‟ of user click streams through a website, and
the flow of fluids in a physical environment in arriving at new
representations.
representation of web access involves locating „abstract‟ concepts (e.g.
web pages) within a geometric space.
Structures used:
- Graphs
Extract tree from the site structure, and use this as the
framework for presenting access-related results through glyphs and
color mapping.
- Stream Tubes
Variable-width tubes showing access paths with different traffic are
introduced on top of the web graph structure.
60. This is a visualization of the

(entry point into clusters) to Blue (exit
points) clarifies behavior of users.
This is a 3D visualization of web
usage for above site.The cylinder like
part of this figure is visualization of
web usage of surfers as they browse
a long HTML document.
62. User’s browsing access pattern is
amplified by a different
coloring. Depending on link structure
of underlying
pages, we can see vertical access
patterns of a user drilling down the
cluster, making a cylinder shape
(bottom-left corner of the figure). Also
users following links going down a
hierarchy of webpages makes a cone
shape and users going up
hierarchies,e.g., back to main page of
website makes a funnel shape
(top-right corner of the figure).
63. Right: One can observe long user sessions as strings falling off clusters. Those are special type of
long sessions when user navigates sequence of web pages which come one after the other under
a cluster, e.g., sections of a long document. In many cases we found web pages with many nodes
connected with Next/Up/Previous hyperlinks.

64. Frequent access patterns
extracted by web mining
process are visualized as a
white graph on top of
embedded and colorful graph
of web usage.
65. Similar to last figure with
addition of another attribute,
i.e., frequency of pattern which
is rendered as thickness of
white tubes; this would
significantly help analysis of
results.
66. Future Work
A number of further tasks could be added:
Demonstrating the utility of web mining can be done by making exploratory
changes to web sites, e.g., adding links from hot parts of web site to cold parts
and then extracting, visualizing and interpreting changes in access patterns.
There is often a tension in the design of algorithms between accommodating a
wide range of data, or customizing the algorithm to capitalize on known
constraints or regularities.
Also web content mining can be introduced to implementations of this
architecture.
