Patent Application
20100082612
Most image files on the web do not contain information pertaining to its locations stored therein. As a result, internet search engines rely on a web user's description of an image to conduct a search for the image. The web user's description may include text that may relate to the image or may describe the geographical location of the image. Internet search engines use this text input to search the surrounding text of a webpage, an image caption, an image file name, or information stored in the metadata of the image file. Unfortunately, these text fields may not accurately describe the actual image, and thus the results of the image search may not display the web images that the user intended for.
Described herein are implementations of various technologies for using a game to determine the relevance of an image with respect to its location. In one implementation, the game may be a web-based, multiplayer game that may be used to collect geographical data that may describe the location of an image. The game may display a portion of the image to the user and request that the user identify the geographical location that the image may relate to. Additional portions of the image may be revealed as the user continues playing the game until the user determines the location of the image. The game may then generate a score for the user. The score may be based on the distance between the user's answer and the actual location of the image, the time in which it took for the user to determine the location, the amount of the image that was displayed to the user, the difficulty level of the location or the image, if the user used a hint function, and/or combinations thereof.
The game may then evaluate the frequency that a particular image or image region was used, the scale of the image region used to identify the location of the image, and the score generated for the user after identifying the image, in order to determine the relevance between an image and its location. The relevance may be represented by a value and stored in a game log along with additional information pertaining to the image. A search engine may use the game log to rank the image search results as per its relevance to the search criteria. The image search results may comprise a list of web images that may more accurately reflect the intended web images that the user was searching.

The web game application 61 may interface with the game application 60, and it may be used to determine the location of an image. The web game application 61 will be described in more detail with reference to
It should be understood that the various technologies described herein may be implemented in connection with hardware, software or a combination of both. Thus, various technologies, or certain aspects or portions thereof, may take the form of program code (i.e., instructions) embodied in tangible media, such as floppy diskettes, CD-ROMs, hard drives, or any other machine-readable storage medium wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing the various technologies. In the case of program code execution on programmable computers, the computing device may include a processor, a storage medium readable by the processor (including volatile and non-volatile memory and/or storage elements), at least one input device, and at least one output device. One or more programs that may implement or utilize the various technologies described herein may use an application programming interface (API), reusable controls, and the like. Such programs may be implemented in a high level procedural or object oriented programming language to communicate with a computer system. However, the program(s) may be implemented in assembly or machine language, if desired. In any case, the language may be a compiled or interpreted language, and combined with hardware implementations.
In one implementation, the location of an image may be determined by a user via the web game application 61. The web game application 61 may be played in three different modes: cooperative, competition, or versus. The goal of each game mode is for one user to identify the location of an image. The cooperative mode may be designed to have two players assist each other in determining the location of the image, but the competition and versus modes may be designed such that one player tries to make it more difficult for the other player to determine the location of the image. Although each mode may allow the user to play the game differently, the information obtained by each game mode may be used to determine the relevance of each image with respect to its location information.
At step 205, the web game application 61 may receive a location selection from a user. The location may refer to a geographical entity such as a continent, country, state, city, or the like. In one implementation, the web game application 61 may request that the user selects a city. Typically the user may select a city that he may be familiar with in order to accurately determine the location of an image within the city's geographical limits.
At step 210, the web game application 61 may generate a list of scenes based on the input of the user at step 205. In one implementation, the web game application 61 may generate a list of scenes that may relate to different aspects of the location received at step 205. For example, if the user selected New York City at step 205, the web game application 61 may generate scenes of places located inside New York City such as Central Park, downtown, Times Square, or the like.
At step 215, the web game application 61 may randomly select or receive a scene selection from the user. In one implementation, the web game application 61 may randomly select a scene, or it may receive a scene selection from the user, depending on the mode of operation the web game application 61 may be in. In the versus mode, the web game application 61 may randomly select a scene related to the location received at step 205, but the user may select a scene in the cooperative or competition modes.
At step 220, the web game application 61 may generate a list of images that may represent the scene received at step 215. In one implementation, the web game application 61 may perform a search for images on an internet search engine using the scene received by the user as its search criteria. The web game application 61 may display the results to the user as a list of images related to the scene.
At step 225, the web game application 61 may receive an image selection from the user. In the competition and versus mode of the game, the web game application 61 may randomly select an image from the list generated at step 220, but the user may select an image in the cooperative mode. In the cooperative mode, one player may select an image that may assist another player in determining the location of the image. In one implementation, for the competition and versus modes, the web game application 61 may select and image that may have been frequently selected in the cooperation mode so that players may play with images related to the scene and so that additional information may be efficiently collected into the game logs for those images.
At step 230, the web game application 61 may then receive an image region selection from the user. The image region may include only a portion of the image. For example, an image region may consist of the bottom half of the image or a small fraction of the whole image. The amount of the image region that may be displayed may be set by the web game application 61. In one implementation, the web game application 61 may allow a user to display a region of the image that may consist of a circle that may account for a certain percentage of the image. In the cooperation mode, one player may select an image region that may indicate to another player the location of the image. In the competition and versus modes, one player may select an image region that may make it difficult to indicate to another player the location of the image. Although the various modes may have been described to require two players, it should be noted that the web game application 61 may simulate the actions of one player in the various modes of the game.
At step 235, the web game application 61 may display the selected image region. In one implementation, the selected image region may increase in size as time elapses.
At step 240, the web game application 61 may receive a location that may pertain to the image from a user. In one implementation, the user may choose to pass step 240. If the user does not input location information at step 240, the web game application 61 may return to step 230 and receive another image region selection. The web game application 61 may then repeat steps 230-240 until the user identifies the location of the image. When the user identifies the location, the web game application 61 may proceed to step 250.
At step 245, the web game application may calculate a score for the user who identified the location of the image and a relevance value for the image. In one implementation, the score that the user may receive for identifying the image may be based on the image that was used during the game and the specific region of the image that was displayed prior to the user identifying the image. The score may also be based on the distance between the user's answer and the actual location of the image, the time in which it took for the user to provide an answer, the amount of the image that was displayed to the user, the difficulty level of the location or the image, if the user used a hint function, and/or combinations thereof. Different geographical entities, different scenes, different sets of images and image regions may have different difficulty levels. The difficulty levels may be assigned based on play logs or prior knowledge.
The web game application 61 may also calculate a relevance value to denote the relevance between the image and its location. The calculation of a relevance value may account for the frequency in which an image was successfully used to describe a location, the frequency in which an image region was successfully used to describe a location, the scale of the image region that was successfully used to describe a location, the score a user obtained after successfully describing the location of an image, and/or combinations thereof. In one implementation, the web game application 61 may calculate the relevance of the image using a straightforward approach, such as a weighted sum of all the listed factors.
At step 250, the web game application 61 may store information pertaining to the user's game play activities along with other information about the game play into a game log. Other information about the game play may include a record of the image used, the image region that was displayed prior to the user identifying the location of the image, the scale of the image displayed prior to the user identifying, the score the user received for identifying the image location, the relevance value of the image, and/or combinations thereof. The game log may be stored on the hard drive 27 or on the memory storage device 50 of a server that may be accessed by an internet search engine.
Although the method 200 has been described to determine the relevance between an image and its location, it should also be noted that the method 200 may also be used to determine the relevance between an image and the content of the image. For example, the method 200 may be used to determine the relevance between an image and a celebrity in the image, a sports team in the image, an object in the image, or the like.
Although the method 200 has been described to be executed by the web game application 61, it should be understood that in some implementations the game client application 60 may be used to determine the relevance between an image and its location. Additionally, it should be understood that while the operational flow diagram 300 indicates a particular order of execution of the operations, in some implementations, certain portions of the operations might be executed in a different order. In one implementation, method 300 may be performed by the search engine application 62.
At step 310, the search engine application 62 may receive a request to search for one or more images that may be stored on a webpage. When receiving the request to search for images, the search engine application 62 may receive one or more search criteria from a user that may describe the image that the user is in searching. In one implementation, the search criteria may include information pertaining to the geographical location of the image. For example, if a user is in search of an image of the White House in Washington D.C., he may use “Washington D.C.” as the search criteria for locating an image of the White House.
At step 320, the search engine application 62 may receive a game log that may be created by the web game application 61 as described in
At step 330, the search engine application 62 may perform a search for one or more images that may reflect the search criteria provided by the user at step 320. In one implementation, the search application 62 may use the game log in addition to its traditional methods for conducting a search for images.
At step 340, the search engine application 62 may retrieve a relevance value for each resulting image from the game log generated in
At step 350, the search engine application 62 may display a list of images that may match the search criteria provided by the user in an order of its relevance value with respect to the search criteria.
