In this lecture, we will introduce several metrics and techniques for dealing with the size and other evolution rates of the web. The exponential growth of the web poses a serious challenge for the Internet/web search services (publicly known as search engines), due to the fact that their effectiveness relies on their information coverage. However, web search services not only have to cover an increasing quantity of information, but also to deal with evolution incidents, since new web documents and objects are relentlessly added, old ones are moved, while others frequently have their content changed or updated. The problem of measuring such characteristics stands as a non-trivial problem due to the nature and the structure of web itself. We will present measurements derived from real experiments conducted in the well-known Internet search services such as Google and MSN.
