Abstract: Advertisement quality measures (e.g., predicted click through rates) are modified in accordance with a user's preferences with respect to domains to which the advertisements relate.

Abstract: Systems and methods for optimizing traffic in a data network are provided. Network traffic may be optimized by associating costs with data links that connect network nodes. The method includes determining a set of lowest cost paths between a source network node and a destination network node. Paths that contain loops may be excluded from the set of lowest cost paths. Exploration of certain paths may also be delayed or prevented entirely.

Abstract: A method of adding web-based content to a web notebook can include producing multiple search results responsive to a search request; generating in the multiple search results multiple corresponding icons, each of which, when invoked, causes content associated with a corresponding search result in the multiple search results to be placed in a web notebook associated with a user account; and forming a correlation between one of the multiple search results and the web notebook.

Abstract: A system receives a search query from a user and searches a corpus of documents using the received search query to determine a set of search results. The system provides the set of search results to the user and receives a request from the user to save one or more selected search results of the set of search results. The system saves the selected one or more results in a database in response to the request and uses the saved one or more results as indicators of search result quality for subsequent related searches.

Abstract: Methods and systems to modify the number and/or positioning of advertisements presented to a user based on that user's activity patterns (e.g., previous queries, query result selections, ad selections, etc.) and the order in which events constituting the activity patterns occurred. For example, the methods and systems can be based on a Markov model utilizing the user's activity patterns.

Abstract: A method of adding web-based content to a web notebook can include producing multiple search results responsive to a search request; generating in the multiple search results multiple corresponding icons, each of which, when invoked, causes content associated with a corresponding search result in the multiple search results to be placed in a web notebook associated with a user account; and forming a correlation between one of the multiple search results and the web notebook.

Abstract: A method of presenting computer-generated search result information can include receiving a search request from a client computer; identifying a plurality of search results responsive to the search request; ranking the plurality of search results using content in one or more web notebooks; and providing the ranked plurality of search results for presentation in the client computer. Using the content can include determining whether at least one of a title, a heading, clipped content, metadata or a user-annotation in at least one web notebook relates to the search request and, if so, increasing a ranking of at least one search result referenced by the at least one web notebook.
