Abstract: A computer-implemented method includes prompting a user to provide an authentication typing sample by entering an authentication phrase on a keyboard, in order to authenticate the user submitting coursework in an online education course. The method involves determining whether the authentication typing sample matches an enrollment typing sample captured earlier. In the event the authentication typing sample matches the enrollment typing sample, the method involves authenticating the user's identity and accordingly determining whether the coursework is successfully submitted and signed by the user.

Abstract: A method includes, in connection with a submission of a user's coursework in an online education course event, prompting the user to provide authentication information for a user authentication process, which includes any of (1) a social network account login authentication process, (2) comparing a geolocation of the first communication device on which the online education course is presented and a previously registered geolocation, (3) comparing the geolocation of the first communication device and a geolocation of a second communication device associated with the user, and (4) a personalized challenge-response authentication process. The method further includes comparing the authentication information received from the user to stored information associated with the user, and issuing a verified credential to the user based on the comparing and on completion of the user's coursework.

Abstract: Performing identity verification for online education is disclosed. In response to receiving a notification of a submission event, a user is prompted to provide authentication information including at least one of a plurality of types of information. Authentication information received is compared to at least a portion of stored enrollment information associated with the user with which the received authentication information is associated. The stored enrollment information includes at least two different types of information collected during an enrollment phase, including the at least one type of information solicited during the user prompting. In the event that matching criteria are met based at least in part the comparison a first action is performed. In the event that matching criteria are not met based at least in part on the comparison, a second action that is different from the first action is performed.

Abstract: Techniques are provided for designating an item as being of a particular type when the item has been selected after being returned in response to a search and by identifying which mode, of a plurality of modes, in which the search engine was operating when the item was selected.

Abstract: Techniques are provided for automatic product categorization. In one aspect, the categorization is based on text and one or more other values associated with a product offering. In another aspect, a first categorization of a product offering is performed and, if the product category chosen is in a set of co-refinable product categories, then a second (or third, fourth and so on) categorization is performed among the set of co-refinable product categories. In a third aspect, products are categorized based on cost. In another aspect, after products are categorized, the products are flagged for further categorization processing if the cost for categorizing the product is beyond a predefined threshold.

Abstract: Techniques are described herein for providing search results that are ranked based on a predictor that predicts, for each of a number of objects, likelihoods that each particular object will be selected at different positions on a results list.
