Techniques are provided through which 'suspicious' websites may be identified automatically. A suspicious website is one that is associated with many changes or an inconsistent number of changes in web registry information over time. Registry information is received when changes to the registry information occur. The registry information is referred to as a transaction. A transaction is comprised of a plurality of values that each correspond to a characteristic. A characteristic is a property of a website, such as the website's contact information. A count associated with a particular characteristic-value pair is updated each time the particular value is identified in a transaction. A high count indicates that the website associated with the particular value is associated with a lot of changes. Therefore, a website associated with a high count is suspicious. Other factors that may be used for identifying a 'suspicious' website include how often and how much the count changes.

Identifying exceptional web documents

A method and apparatus for improving search results is provided. The method works by delineating sections of a document that are not relevant to the main content. The document content is subjected to ranking analysis in entirety. In response to a query results are recalled omitting terms included in the no-recall sections. Terms in the no-recall sections are not used in titles and abstracts of the results. The results are ordered at least in part by the rankings attributed to the identified no-recall sections.
