20100205213 | NON-EXACT CACHE MATCHING - The subject matter disclosed herein relates to returning cached object results based at least in part on a non-exact comparison with a query key. | 08-12-2010 |
20100250528 | QUICKLINK SELECTION FOR NAVIGATIONAL QUERY - According to techniques described herein, the best set of quicklinks is picked to maximize the benefits for a majority of the users of a search engine, since the “real estate” on a search results page is constrained and valuable. Quicklinks are navigational shortcuts that are displayed below the website homepage on a search results page. Using user browsing trails obtained from browser toolbars, and a simple probabilistic model, the quicklink selection program is formulated as a combinatorial optimization problem. Two techniques are proposed herein: a greedy technique and a tree-based technique. The tree-based technique finds an optimal solution, but may do so in a greater amount of time than the greedy technique takes to find a solution that is not guaranteed to be optimal. The tree-based technique may incorporate natural constraints on the set of chosen quicklinks. | 09-30-2010 |
20100325129 | DETERMINING THE GEOGRAPHIC SCOPE OF WEB RESOURCES USING USER CLICK DATA - A geographic region is automatically determined for an Internet resource based on information that has been gathered over time through the automatic monitoring of certain “click” activities of Internet search engine-using users. Over time, the search engine collects information for each click. Using this click-related data, the search engine estimates the geographic region with which the resource ought to be associated. The fact that a significant proportion of clicks on a resource's hyperlink are clicks that “came through” a search engine portal that is associated with a geographic region tends to suggest that the resource ought to be associated with that geographic region. Similarly, the fact that a significant proportion of clicks on a resource's hyperlink are clicks that were made by users whose computers have IP addresses that are associated with a geographic region tends to suggest that the resource ought to be associated with that geographic region. | 12-23-2010 |
20110055132 | IDENTIFICATION AND MEASUREMENT OF SOCIAL INFLUENCE AND CORRELATION - Techniques for detecting social influence between users in a set of users with regard to an activity are provided. Data for each user of the set of users is received that includes a time value at which the user became active with regard to the activity, and includes at least one indication of another user in the set of users associated with the user. A first estimate of social correlation in the set of users is determined based on the data. The data is modified. For instance, the data may be modified according to a shuffle test and/or an edge reversal test. A second estimate of social correlation in the set of users is determined based on the modified data. The first estimate is compared to the second estimate to determine a degree of social influence in the set of users. | 03-03-2011 |
20110060746 | MATCHING REVIEWS TO OBJECTS USING A LANGUAGE MODEL - A method is provided to associate reviews that have unknown correspondences to tangible entities to structured objects that have known correspondences to tangible entities comprising: transforming a respective review and text from a respective structured object to a collection of words that intersect the respective review and text from the respective structured object; determining a measure of a likelihood of a match as a function of respective probabilities of occurrences of respective words of such intersecting collection within generic review text and respective probabilities of occurrences of respective words of such intersecting collection within structured object text. | 03-10-2011 |
20110191167 | SYSTEM AND METHOD FOR EXPLORING NEW SPONSORED SEARCH LISTINGS OF UNCERTAIN QUALITY - According to some example embodiments, a method includes calculating learning values associated with a plurality of listings, at least one of said learning values associated with one of said listings representing a value based, at least in part, on a probability distribution of selections of said listing. The method further includes applying said learning values to ranking scores associated with said listings to provide an updated ranking, and electronically auctioning advertising inventory to purchasers associated with said listings based, at least in part, on said updated ranking. | 08-04-2011 |
20110196722 | MARKETPLACE FOR CAPTCHA DEVELOPERS - Techniques are described herein for providing a marketplace for CAPTCHA developers. A CAPTCHA is a type of challenge-response test that a content provider may present to users for authorizing the users to access content that is hosted by the content provider. CAPTCHA developers may propose CAPTCHAs for testing in the marketplace. A server is configured to provide instances of proposed CAPTCHAs to users along with instances of reference CAPTCHAs that have known difficulties to determine the relative difficulties of the proposed CAPTCHAs for the users. The server may determine a reward to be provided to a developer of a proposed CAPTCHA based on a difficulty that the predetermined automated systems encounter when they attempt to solve the proposed CAPTCHA and an ease with which the users solve the proposed CAPTCHA. The server may determine rewards to be provided to developers of predetermined automated systems that solve the proposed CAPTCHAs. | 08-11-2011 |
20110197268 | CAPTCHAS THAT INCLUDE OVERLAPPED CHARACTERS, PROJECTIONS ON VIRTUAL 3D SURFACES, AND/OR VIRTUAL 3D OBJECTS - Techniques are described herein for generating CAPTCHAs that include overlapped characters, projections on virtual three-dimensional (3D) surfaces, and/or virtual 3D objects. A CAPTCHA is a type of challenge-response test that a content provider may present to users for authorizing the users to access content that the content provider hosts. For example, when a user attempts to access content, a CAPTCHA may be generated in accordance with one or more of the techniques described herein and provided to the user. The user may be asked to identify characters that overlap in the CAPTCHA, characters that are projected on a virtual 3D surface, and/or a designated virtual 3D object, so that the user may be authorized to access the content. The user may enter the characters and/or select the designated virtual 3D object that is identified in the CAPTCHA using an input device, such as a keyboard, touch screen, pointing device, etc. | 08-11-2011 |
