Patent Application
20070130203
At least one embodiment of the present invention pertains to information management and retrieval in general, and more particularly, to method and system to provide targeted advertising with search results.
The World Wide Web (the “Web”) provides a breadth and depth of information to users. Typically, a user accesses portions of the information by visiting a World Wide Web (“Web”) site. Due to the rapid growth of the Web and the number of Web sites accessible via the Web, it is often difficult for a user looking for information about a particular topic to determine if a Web site exists that contains such information, which Web site to go to, or what the Uniform Resource Locator (URL) is for a web site of interest.
As a result of a desire by users to search for relevant Web sites related to various topics of interests, some Web sites provide search services to allow users to search for content on the Web via a browser application present on the user's computer system. When a user submits a query with one or more search terms or keywords to a search script running in the users browser, the search engine that provides the search script to the browser may communicate search results to the user based on the search terms or keywords.
Advertising with search engines, sometimes referred to as sponsored search, may allow advertisers to target specific users with certain interests. For example, advertising may be based on a keyword search. Some providers of search engines offer services that allow an advertising entity to have a link to their website featured when a user enters particular keywords specified by the advertising entity. Advertising may also be based on content context. For example, a search engine provider may have partner websites with specific content. Partner websites may allow search engines to place content-specific advertising on the partner website, for example, in return for a fee.
Some existing search engines provide video search functionality in addition to text search and image search. Video search results are sometimes displayed in a form of still pictures with associated links. In order to view a video associated with a particular search result, a user may invoke the associated link to trigger the streaming of the selected video. Existing systems, however, do not provide targeted advertisements with video search results.
The present invention includes methods and related apparatus to present targeted advertisements with search results. In one embodiment, the system comprises a query component to detect a request for a search and an advertisement selector to present one or more video advertisements to a user according to characteristics associated with the search. In another embodiment, the system comprises a query component to detect a request for a video search and an advertisement selector to present one or more advertisements to a user according to characteristics associated with the video search.
Other aspects of the invention will be apparent from the accompanying figures and from the detailed description that follows.
One or more embodiments of the present invention are illustrated by way of example and not limitation in the figures of the accompanying drawings, in which like references indicate similar elements and in which:
As described in detail below, the technique introduced herein addresses the need to provide enhanced advertising experience for Internet users. In one embodiment of the present invention, when a user submits a query to a search engine to request data based on the terms of the query, the search engine delivers targeted advertisements to the user in addition to the search results. For example, in response to a request for a search (e.g., news, Web, image, shopping, usenet, etc) a user may be presented with one or more advertisements, such as video advertisements. In another embodiment, advertisements that are presented to a user with the results of a video search may comprise text, URLs, images, as well as audio and video streams.
A search engine, in one embodiment, may analyze characteristics of the search request and select advertisements that are determined to be appropriate for the originator of the request. The characteristics of the search that a search engine may utilize in order to provide targeted advertisements may include search keywords, as well as user-specific data. User-specific data may include demographic information for the user, previous queries history for the user, an associated IP address, etc.
In one embodiment, a search engine may also provide preview capability, in order to allow a user to evaluate advertisements and search results in an efficient manner. For example, when a user moves a pointer over a search result or over an advertisement, the associated video can be animated in a high-resolution mode and, in some embodiments, with audio.
For the purposes of this description, the term “client system” refers any computing device, including a laptop computer, notebook computer, personal digital assistant (PDA), or handheld wireless phone. The term “server system” refers to any computer system or similar mechanism that stores information and provides information in response to a user request received from a client computer, and/or provides some service. A particular computer system may function both as a client and as a server.
The client system 120, as shown in
In one embodiment of the present invention, users of the client systems 120 may access Web searching services provided by a search engine 140. A search engine, generally, is a service designed to help find information stored within an information space such as the World Wide Web. The search engine 140 allows users of the client systems 120 to request content according to specific criteria (e.g., a plurality of keywords or phrases). The search engine 140 may identify and retrieve content items that match those criteria. In order to process search requests quickly and efficiently, the search engine 140 may use regularly updated indexes associated with content available on the Web. In one embodiment, users may utilize search functionality of the search engine 140 to request and access video content.
In one embodiment, the search database 240 may store a set of advertisements, e.g., as full encoded videos. The search database 240 may also store lower-resolution versions of video advertisements. A lower-resolution version of a video may be generated by the search engine 200 utilizing a re-encoder 260.
Video advertisements stored in the search database 240 may be annotated with keywords extracted from respective Web pages associated with the videos. An advertising video may also be annotated with keywords extracted from the audio track contained in the video, e.g., utilizing any of the so-called speech-to-text programs. Each keyword associated with a particular video advertisement can be assigned a weight value, according to the frequency with which a keyword occurs in the text or in the audio track associated with the video.
The weight value assigned to a keyword for a particular video advertisement may be adjusted according to additional information collected by the search engine 200 during users' search sessions. Such additional information may include data that indicates how users react to video advertisements provided with video searches. For example, when a user enters a search keyword and is served search results with video advertisements, the search engine 200 may keep track of the number of times the user moves the mouse over a particular advertisement or the number of times the video advertisement is presented to the user in a high quality mode.
Information associated with users' behavior collected by the search engine 200 may be stored in user profiles 270. The user profiles 270 may also store historical information associated with users' queries in order to improve personalization and targeting of the advertisements served to the users.
In one embodiment, search results and associated advertisements (e.g., video advertisements) provided to a user may be personalized by utilizing data obtained by monitoring the searches. A group of users may be defined based on similarities between search activities performed by the users during a monitoring period. For example, search activities may be tracked by geographical location, by the number of similar web sites visited during the monitoring period, or by the number of similar queries submitted during the monitoring period. Search activities may also be tracked by video advertisements selected in the past by the users, by video advertisements served to users in high-resolution mode with audio, or by any other metric that may be available from the web traffic data. In one embodiment, the web traffic data may be associated with a definitive group of users. A separate history graph may be generated for each defined group of users.
The activities of individual users may be tracked, for example, by the user's IP (Internet Protocol) address and/or by the use of cookies. A history graph associated with the defined group of users may be generated in order to determine personalized search results or advertisements for a particular user. When a new user is identified who exhibits web activity that is similar to one of the defined groups of users (e.g., geographic location, navigation, queries, etc), the search results and advertisements (e.g., video advertisements) to be provided to the new user may be biased by the history graph. The history graph may represent the web activity of the associated group of users for the period of time related to the monitoring period. For example, the bias may have a lifetime that persists for some multiples of the monitoring period used to define the group of users associated with their history graph.
In one embodiment of the present invention, user queries submitted to the search engine 200 are processed by a query component 210. The query component 210 interrogates the search database 240 with keywords and phrases submitted with the query in order to retrieve search results to be provided to the requesting user.
The query component 210 may cooperate with an advertisement (ad) selector 280 to identify one or more advertisements that may be appropriate to serve to the user in response to the particular video search. The ad selector 280 may also be configured to select advertisements to be presented to the user based on IP address of the user's client system 120, or based on other user-specific information (e.g., user's demographic information, user's previous queries, cookies stored on the user's client system, etc.).
Advertisements presented to the user with the results of a video search may be in a form of a text or a uniform resource locator (URL). Advertisements may also be presented as a still picture (e.g., a frame extracted from a video advertisement), an audio track, or a video stream. A video advertisement served to a user may also include an audio stream.
It will be noted, that the components of the search engine 200 shown in
In order to allow multiple advertisements to be presented to a user in addition to the search results (e.g., video search results), the loader 320 may initially load lower resolution versions of the advertisement videos. A user may be allowed to view a higher-resolution version of a video advertisement by simply moving a pointer (e.g., a pointer operated by a mouse device) over a specific video advertisement. The trigger 330 may be configured to detect an event associated with a pointer being moved over a video (a so-called roll-over event) and invoke the mode selector 340. The mode selector 340 may then replace the specific low-resolution video with a higher resolution version of the video. As mentioned above, a higher-resolution version of a video advertisement may be stored in the search database 240 illustrated in
In one embodiment, a higher-resolution version of a video advertisement may be referred to as a preview mode. When a video advertisement is switched by the mode selector 340 to a preview mode, the mode selector 340 also may pause the streaming of video for the rest of video advertisements presented to a user. It will be noted, that the preview technique discussed herein may be utilized to allow a preview of advertisements, as well as preview of search results. Allowing a preview of a selected search result or an advertisement may comprise providing to user additional information regarding the selected object. For example, in one embodiment, additional information may include audio or video streams, or a combination of audio and video.
Thus, in one embodiment of the present invention, the search service 300 may allow a user to view multiple videos (advertisements or search results, or both) simultaneously in streaming mode, and to preview individual videos by selecting a particular video (e.g., by rolling a pointer over an associated displayed object).
Referring to
At block 408, the search results (e.g., video search results) are presented to the user along with the determined advertisements (block 410). When advertisements are presented in a form of video objects, a user may be allowed to preview the associated video advertisements, as descried above.
Referring to
When a user moves the pointer off of the video object that is being presented in a preview mode, the trigger 330 (illustrated in
It will be noted, that although one operation of methods 400 and 500 may precede another operation, the order of some operations in methods 400 and 500 may be reversed, or the operations may be performed in parallel. For example, in method 500, the displaying of the determined object in preview mode may be performed subsequent to or in parallel with pausing the streaming of other video objects.
The exemplary computer system 700 includes a processor 702 (e.g., a central processing unit (CPU) a graphics processing unit (GPU) or both), a main memory 704 and a static memory 706, which communicate with each other via a bus 708. The computer system 700 may further include a video display unit 710 (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)). The computer system 700 also includes an alphanumeric input device 712 (e.g., a keyboard), a cursor control device 714 (e.g., a mouse), a disk drive unit 716, a signal generation device 718 (e.g., a speaker) and a network interface device 720.
The disk drive unit 716 includes a machine-readable medium 722 on which is stored one or more sets of instructions (e.g., software 724) embodying any one or more of the methodologies or functions described herein. The software 724 may also reside, completely or at least partially, within the main memory 704 and/or within the processor 702 during execution thereof by the computer system 700, the main memory 704 and the processor 702 also constituting machine-readable media. The software 724 may further be transmitted or received over a network 726 via the network interface device 720.
While the machine-readable medium 722 is shown in an exemplary embodiment to be a single medium, the term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “machine-readable medium” shall also be taken to include any medium that is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the present invention. The term “machine-readable medium” shall accordingly be taken to include, but not be limited to, solid-state memories, optical and magnetic media, and carrier wave signals.
