Title: System and method for updating search advertisements during search results navigation

Description:
FIELD OF THE INVENTION 
     The invention relates generally to computer systems, and more particularly to an improved system and method for updating search advertisements during search results navigation. 
     BACKGROUND OF THE INVENTION 
     Sponsored advertising is a widely used mechanism for selling advertisements using Internet search engines. Each time a user enters a search term into a search engine, advertising space may be allocated within that user&#39;s search results. For example, a sponsored search advertising area may be used for displaying sponsored advertisements on a search results web page. There are various methods for selling sponsored advertising in online search advertising including keyword auctions where keywords of a user&#39;s query may be auctioned to an advertiser who is the highest bidder with sufficient budget. Search engines&#39; revenues from sponsored advertising are currently on the order of ten billion dollars per year. 
     When a user enters a search term into a search engine, the sponsored advertisements selected for display to the user are based on the initial search terms in the query submitted. Although a user has a search intention when conducting a search, it is often difficult to derive the user&#39;s search intention initially because of the limitations of current natural language processing. For example, when a user searches for the query, “chef&#39;s knife”, it is unclear whether the user is interested in purchasing a chef&#39;s knife or whether the user might be really looking for a local sharpening service for a particular brand of chef knives. The user&#39;s search intention cannot be directly inferred from the initial search keywords, so sponsored advertisements displayed with the initial search results may not be very relevant. Furthermore, a user could change the search intention during a search session. Unfortunately, this can make it difficult to directly infer the user&#39;s search intention. 
     What is needed is a way to provide advertisements that are more relevant to users&#39; interest. Such a system and method should be able to discover the users&#39; intent of the search query to provide more relevant advertisements. 
     SUMMARY OF THE INVENTION 
     Briefly, the present invention may provide a system and method for updating search advertisements during search results navigation. In various embodiments, a client computer may be operably connected to a search server and an advertisement server. The client computer may include a sponsored advertisement update component operably coupled to a search result click event monitor that receives an address of a web page selectable from the search results web page. The sponsored advertisement update component may send a request that includes an address of a web page selected from a search results web page to update sponsored advertisements displayed in a sponsored advertisement area of the search results web page. In response to receiving a search query, a search server operably coupled to the client may add to a search results web page executable instructions for the search result click event monitor to receive an address of a web page selectable from the search results web page in order to send the click event to the advertisement server to update sponsored advertisements displayed in the sponsored advertisement area of the search results web page. The search server may also send a request with query features and user features to the advertisement server to serve a list of sponsored advertisements for display with the search results of query processing. 
     The advertisement server may be operably coupled to an advertisement serving engine that may include a sponsored advertisement selection engine that selects an update of sponsored advertisements using web page features of a web page selected from the search results web page in addition to using query features and user features. The advertisement serving engine may also include a sponsored advertisement scoring engine that scores candidates for the update of sponsored advertisements using query features, user features and web page features. The advertising serving engine may rank candidates for the update of sponsored advertisements in descending order by score and send a list of sponsored advertisement with the highest scores to the client computer for display in the sponsored advertisement area of the search results web page. Upon receiving the update of sponsored advertisements, the client computer may display the updated sponsored advertisements in the sponsored advertisement area of the search results web page. 
     In general, the present invention may effectively provide the capability for a user to receive updated sponsored advertisements displayed on a search results web page during navigation of search results from a search query. To do so, a web browser executing on a client computer may receive a search query input by a user and may send the search query request to a search server. In response, the search server may return search results with executable instructions that monitor events selecting an address of a web page in the search results web page to the web browser executing on the client. An address of a web page may be selected in the search results web page on the client, and a request that includes an address of a web page selected from a search results web page may be sent from the client computer to an advertiser server to update sponsored advertisements displayed in a sponsored advertisement area of the search results web page. 
     In response, the advertisement server may selects an update of sponsored advertisements using query features, user features and web page features of the web page selected from the search results web page. Candidate advertisements for the update of sponsored advertisements may be scored using query features, user features and web page features, and the candidate advertisements may be ranked in descending order by score. A list of sponsored advertisement with the highest scores may be send as an update to the client computer for display in the sponsored advertisement area of the search results web page. Upon receiving the update of sponsored advertisements, the client computer may display the updated sponsored advertisements in the sponsored advertisement area of the search results web page. 
     Advantageously, the present invention may effectively refine a user&#39;s search intention by tracking the user&#39;s interaction with search results and may deliver more personalized search advertisements to a user during navigation of search results. After receiving search results, more relevant advertisements may be selected by refining query features using web page features identified from navigation of search results. Updated search advertisements may be generated and displayed for a user to view. Other advantages will become apparent from the following detailed description when taken in conjunction with the drawings, in which:

There may also be sponsored search advertisements such as the list of sponsored search advertisements  310  displayed in another area of the search results page dedicated for sponsored search advertisements such as the area depicted with sponsor results. A user may select a URL displayed in a search results page to request content of a web page, and a click event with the URL of the web page selected may be sent to an advertisement server that may use features of the web page along with query features and user features to update a list of sponsored advertisements displayed on the search results page. The updated list of sponsored advertisements may be sent to the client device for display in the sponsored search advertisements area of the search results page. 
       FIG. 4  presents a flowchart generally representing the steps undertaken in one embodiment for updating search advertisements during search results navigation. At step  402 , a search query may be sent by a client device to a search engine to obtain search results. At step  404 , search results may be received by the client device from a search engine, such as search engine  214 , and sponsored advertisements may be received by the client device from an advertisement serving engine, such as advertisement serving engine  228 . A user may select a URL displayed in a search results page to request content of a web page, and as a result, a click event with the URL of a web page requested from search results may be received at step  406  by the client device. At step  408 , the click event with the URL of a web page requested from search results may be sent by the client device to an advertisement server. 
     The advertisement server may then select an updated list of sponsored advertisements at step  410  using query features, user features, and web page features of the web page requested from search results. In an embodiment, the query features may include the terms used in the search query, and the user features may include geographic attributes such as zip code, demographic attributes such as age and gender, and behavioral attributes associated with the user. The web page features may include unigrams and phrases of content of the web page, categories of the web page, geographic attributes of the web page, and so forth. At step  412 , an updated list of sponsored advertisements may then be sent from the advertisement server to the client device for display in the sponsored advertisement area of the search results web page. And the updated list of sponsored advertisements may then be displayed in the sponsored advertisement area of the search results page at step  414 . 
       FIG. 5  presents a flowchart generally representing the steps undertaken in one embodiment on a client for updating search advertisements during search results navigation. At step  502 , a search query may be sent by a client to a search engine, and search results and sponsored advertisements may be received at step  504  by the client device. In addition, executable instructions for monitoring click events by a user to select a search result may be received at step  506 . In an embodiment, the executable instructions may be a script, such as JavaScript, that is added to an HML (Hypertext Markup Language) or an XML (Extensible Markup Language) document that encodes the search results page. 
     A user may select a URL displayed on a search results page to request content of a web page, and as a result, a click event with the URL of a web page requested from search results may be received at step  508  by the client device. In an embodiment, a click event monitor  208  with the executable instructions for monitoring click events by a user to select search results may receive the click event. At step  510 , the click event with the URL of a web page requested from search results may be sent by the client device to an advertisement server which may send an updated list of sponsored advertisements for display in the sponsored advertisement area of the search results page. An updated list of sponsored advertisements from the advertisement server may then be received at step  512  by the client device. And the client device may display the updated list of sponsored advertisements in the sponsored advertisement area of the search results web page at step  514 . Those skilled in the art will appreciate that while the advertisement server may select an updated list of sponsored advertisements, the web browser executing on the client device may send a request to fetch the web page, and, when the web page is received, the web browser may open a new window on the client device in an embodiment to display the content of the web page requested from search results. 
       FIG. 6  presents a flowchart generally representing the steps undertaken in one embodiment on a search server for updating search advertisements during search results navigation. At step  602 , a search query from a client may be received by the search server. In response, a list of URLs of web pages may be obtained for search results at step  604 . At step  606 , a search results page may be constructed with the list of URLs of web pages, and executable instructions that monitor click events by a user to select a URL from the search results may be added to the search results page. In an embodiment, the executable instructions may be a script, such as JavaScript, that is added to an encoding of a document that represents the search results page. At step  608 , a search server may send to an advertisement server query features and user features in a request to send sponsored advertisements to a web browser for display in the sponsored advertisement area of the search results page. And a search results page with a list of URLs of web pages and with executable instructions for monitoring click events may be sent to a client device at step  610 . 
       FIG. 7  presents a flowchart generally representing the steps undertaken in one embodiment on an advertisement server for updating search advertisements during search results navigation. At step  702 , a click event with the URL of a web page requested from search results on a client device may be received by an advertisement server. The advertisement server may obtain web page features at step  704  for the web page requested from search results. In an embodiment, the web page features may be retrieved from an index of web pages that includes web page features in storage on a search server. 
     The advertisement server may then select a candidate list of sponsored advertisements at step  706  using query features, user features, and web page features of the web page requested from search results. In an embodiment, a sponsored advertisement selection engine may fetch the posting listing for these query features from an advertisement index. And the advertisement server may score the candidate list of sponsored advertisements at step  708  using query features, user features, and web page features of the web page requested from search results. In an embodiment, a sponsored advertisement scoring engine may score the candidate list of sponsored advertisements based on the vector distance between features. For instance, a user, a web page and advertisements may be each represented by several vectors in different spaces. Each vector space may represent a type of feature, such as unigrams, phrases, categories, and so forth. Each dimension of the vector may capture the intensity of that feature. For instance, a web page may have a vector of unigrams, and each dimension of that vector is a frequency value associated with a word. Thus, for each advertisement in the database, the scorer may calculate the distance of the advertisement&#39;s vectors from the vectors of the user and web page for each vector space such as unigrams, phrases, and so forth. Then the scorer will calculate a final score, which represents a linear combination of the individual distances between vector spaces of the advertisement and the user and web page. In an embodiment, the distance may be calculated by cosine similarity. 
     At step  710 , the candidate list of sponsored advertisements may be ranked by score. And sponsored advertisement from the ranked list may be assigned web page placements in the sponsored advertisements area of the search results page at step  712 . In an embodiment, the highest scoring sponsored advertisements from the ranked list of sponsored advertisements are assigned to the available web page placements in order by highest score. And the list of sponsored advertisements assigned web page placements for display in the sponsored advertisements area of the search results page may be sent to a client device at step  714 . 
     Those skilled in the art will appreciate that other scoring techniques may be used. For instance, a scorer can take into consideration the probability of a user click on an advertisement. In this case, the score may represent the probability of a user click on an advertisement if it is served for display in the sponsored advertisement area of the search results page. For such a scorer, the probability database may be initialized during a training phase, and advertisement impressions and user clicks from the traffic event streams may be provided to the scorer for updating the probability database. In various embodiments, vector distance based scoring and probability based scoring may be used together. 
     Thus the present invention may effectively refine a user&#39;s search intention by tracking the user&#39;s interaction with search results and may deliver more personalized search advertisements to a user during navigation of search results. After receiving search results, more relevant advertisements may be selected by refining query features using web page features identified from navigation of search results. While the advertisement server may select an updated list of sponsored advertisements, the web browser executing on the client device may send a request to fetch the web page, and, when the web page is received, the web browser may open a new window on the client device in an embodiment to display the content of the web page requested from search results. And updated search advertisements may be sent to a client device and displayed for a user to view in the sponsored advertisements area of the search results page. 
     As can be seen from the foregoing detailed description, the present invention provides an improved system and method for updating search advertisements during search results navigation. A search server may return search results from a search query with executable instructions that monitor events selecting a web page in the search results. When a web page may be selected in the search results on the client, a request that includes an address of a web page selected from the search results may be sent from the client to an advertiser server to update sponsored advertisements displayed in a sponsored advertisement area of the search results web page. The advertisement server may select an update of sponsored advertisements using query features, user features and web page features of the web page selected from the search results web page.
