In most cases it is not possible for a program to automatically detect which content is relevant and which is not. To be practical the program has to go through a supervised learning procedure to retrieve data extraction rules from a manually labeled example. Manual labeling requires a user to point to the text and images of interest and select a crawling rule (next page element). The rest can be done automatically by the program, which can detect the template pattern from the manual sample and the web page structure based on tree matching algorithm.

The bot detection works with clients that accept cookies and process JavaScript. It counts the client's page consumption speed and declares a client as a bot if a certain number of page changes happen within a given time interval. The session opening anomaly spots web scrapers that do not accept cookies or process JavaScript. It counts the number of sessions opened during a given time interval and declares the client as a scraper if the maximum threshold is exceeded. The session transaction anomaly detects valid sessions that visit the site much more than other clients.

We need php, and a way to interact with the DOM. If you read my previous entry where I talk about php and the DOM , you know of a few options to do that. We will also need an idea of what we want to scrape. Lets start with something simple. We will scrape the box office information from IMDB. We will only do it this one time, but in a real life situation you may want to set a cron job to scrape the data daily, weekly or at any other interval of time.
