2. Web Crowds Visualization and Extracting the flow-line
Concepts
Request-URI
made by browser, composing a object
Object
all the stuffs with one ‘click’
Trail
a pathway that user get objects through
Flowline
average trail made on the objects

3. Web Crowds Visualization and Extracting the flow-line
Object
request time
one or more URIs
Trail
list of objects
referrer consistency
dwell time

4. Web Crowds Visualization and Extracting the flow-line
Mapping
node : object
edge : transition between objects
flowline : visualizing trails on edge
Using SOM
input layer : 2 nodes
Kohonen layer : n nodes in a single row
training set : 2d coordinates
