摘要:
A recommender system determines a probability threshold for an activity-prediction model, and uses the probability threshold to predict whether a user is performing a target activity. To determine the probability threshold, the system computes a set of activity probabilities based on contextual information for a set of historical activities, and based on an activity-prediction model for a target activity. The system then compares a set of probability thresholds with the set of activity probabilities to determine a prediction success rate for each probability threshold. The system computes a utility score for each probability threshold based on the prediction success rates and a utility function, and selects a probability threshold whose utility score is optimal amongst the utility scores of the set of thresholds and greater than or equal to a baseline utility score. The system then assigns the probability threshold to the activity-prediction model.

Embodiments of the disclosed technology provide a system and method for automatically filling paper form with electronic data. The system receives from a user a scanned image of a paper form that includes a plurality of fields. The system then retrieves a schema map that maps the plurality of fields in the paper form to a plurality of fields in an electronic data record associated with the user. Next, the system retrieves data values of the fields in the electronic data record based on the schema map. The system also synthesizes the retrieved data values and the scanned image to create an image of the paper form in which the fields are filled with the retrieved data values.

One embodiment of the present invention provides a system that facilitates contextually specific opportunity-based advertising. During operation, the system collects contextual information associated with a consumer, and determines a current activity and/or a future activity in which the consumer is engaged based on the contextual information. The system then predicts one or more upcoming advertisement opportunities associated with the consumer based on the determined activities, and presents the predicted opportunities to one or more advertisers, thereby allowing the advertisers to determine a bid amount for presenting an advertisement at the predicted opportunities. The system further selects at least one advertisement to present based on one or more of the following: the bid amount, the collected contextual information, an occurrence probability of the predicted advertisement opportunities, content of the advertisement, metadata associated with the advertisement; and presents the advertisement to the consumer.

One embodiment of the present invention provides a method for recommending activities to a user. During operation, the system determines an activity-type distribution based on the user's personal profile and/or population prior information, thereby facilitating prediction of future activities for the user. The system further searches for and receives one or more activities based on the activity-type distribution. The system then scores each received activity and recommends a number of activities to be performed by the user in the future and a number of corresponding venues, based on the activity-type distribution and the weight distribution.

One embodiment of the present invention provides recommender system for generating a recommendation of an item by combining a set of utility models adaptively to facilitate a decision-making process. The system includes a utility model database containing the set of utility models and a query module for receiving at least one query about the item from a querying entity. The system also includes a rule engine to specify a subset of utility models to be applied to the item and to specify a weight function of the specified utility models. Further included in the system is a set generator coupled to the utility model database, the query module, and the rule engine. The set generator computes a set of ratings by applying each of the utility model in the subset to the item and generates an overall rating for the item based on the weight function. The system further a communication module to return the overall rating.

One embodiment provides a system for facilitating document printing from a portable device. During operation, the system receives a document at a server. Next, the system generates a document optical code corresponding to the document. Subsequently, the system communicates the document optical code to the portable device, thereby allowing the portable device to display the document optical code to a scanning mechanism associated with a printer, Next, the system receives a request, indicating the optical code, from the printer. Subsequently, the system retrieves the document in response to the request, and sends the document to the printer.

One embodiment provides a system for printing a document from a portable device. During operation, the system obtains the document to be printed. Next, the system obtains a document optical code that identifies the document. Subsequently, the system displays the document optical code on the portable device in such a way that the document optical code can be scanned and recognized by a scanner associated with the printer. Next, the system allows the printer to retrieve and print the document based at least on the document optical code.

One embodiment of the present invention provides a system for facilitating presentation of activity-based advertising. During operation, the system receives a set of contextual data of a customer and makes a prediction of the customer's future activity. The system then receives a number of advertisements from the advertisers. Based on the prediction, the system chooses a received advertisement to present to the customer. The system further determines the customer's subsequent activity and confirms the prediction of the customer's activity. The system then receives payments from the advertisers whose advertisement is presented based on whether the prediction is confirmed.

One embodiment provides a system for facilitating document printing from a portable device. During operation, the system receives at an email server an email which includes an attached document. Next, the system generates at the email server a document optical code associated with the document, wherein the document optical code can be scanned and recognized by a scanning mechanism associated with a printer. Subsequently, the system attaches the optical code as an additional attachment to the email, thereby allowing a portable device to print the attached document by displaying the optical code to the scanning mechanism associated with the printer.

One embodiment of the present invention provides a system that facilitates presentation of activity-based advertising based on receptive opportunities. During operation, the system identifies a number of topics. The system then receives a number of advertisements from advertisers, wherein a respective advertisement is associated with a topic. For a respective topic, the system determines a number of candidate advertisements associated with that topic to be pending presentations. The system further analyzes an activity in which a customer is engaged. Next, the system identifies a receptive opportunity to present one or more advertisements to the customer based on the activity analysis. The system then determines among the pending presentations one or more advertisements to present to the customer during the identified receptive opportunity. Subsequently, the system presents the determined advertisements to the customer during the opportunity period.
