A machine learning classifier is used to determine whether a web page belongs to a blog, based on a number of characteristics of web pages (e.g., presence of words such as "permalink", or being hosted on a known blogging site). The classifier may be initially trained using human-judged examples. After classifying web pages as being blog pages, the blog pages may be further identified or categorized as top level blogs based on their URLs, for example.
