You may only use basic libraries that come with the standard python or java installation

Application must run from command line and must not require an IDE to operate

You must include a README file that explains how to prepare your assignment parts and also how to operate it.

All code must be clearly commented to explain how functions operate and interact. Output format is up to you but it must be readable and clear

Part 1:

Write a script or application that takes a start page as a command line parameter. From there it crawls a website by following links.

The output of your program should be to screen or to a file. The output should be each page in the site followed by the pages it links to.

Part 2:

In this part, you must parse each page in the site and Tokenise the TEXT of each document, not any irrelevant details.

Create a stop word list made up of the words that appear in every document.

Use Porter Stemmer (from tarterus.org NOT from any other source) to stem the contents Parse the documents and create a TF.IDF weighted Index

Once this is done, you must provide a query application that uses the vector space model to answer a query typed in by the user and return a ranked list of documents that satisfy the information need.

You must provide two parts to this so that the setup does not need to be re-done every time a new query needs to be run. Time is not being graded but it should run within an acceptable time (say 10 minutes..).

Part 3:

Assign the start page (mainpage.html in the sample corpus) a weight of 100 and assume a damping factor of 0.75, calculate the Pagerank of each page in the site after 20 iterations.

Your script or application should take a start page as an argument at the command line and output a file that lists each page and the rank of that page at iteration 20.
