A personal taste assessment and prediction system implements a method of predicting a person's preference for an item. The system may receive identifying information about an item of interest, and it may use the identifying information to access a database of characteristic values for various items and identify one or more characteristics of the item of interest. The system will access a user profile and process the retrieved characteristics with a user profile for a person to generate a predicted rating for the item of interest for the person.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method for predicting a person's preference for an item, comprising, by one or more processors: receiving, via an electronic device, identifying information about an item of interest; accessing a user profile for a person; accessing a database of characteristic values for a plurality of candidate items; using the identifying information to identify a candidate item that corresponds to the item of interest and retrieve one or more characteristics of the identified candidate item; processing the retrieved characteristics with the user profile to generate a predicted rating for the item of interest for the person; and causing the electronic device to output the predicted rating to the person. 2. The method of claim 1, wherein the user profile comprises a preference model representing the person's preference for a plurality of item characteristics. 3. The method of claim 1, wherein the item of interest and candidate items are each consumable items. 4. The method of claim 2, wherein processing the retrieved characteristics with the user profile to generate a predicted rating for the item of interest for the person comprises: identifying one or more characteristics of the item of interest; determining whether the identified characteristics of the item of interest correspond to one or more indicators of preference in the preference model or the preference profile; and based on whether the identified characteristics of the item of interest correspond to one or more indicators of preference, generating a prediction of whether the person is likely to exhibit a preference for the item of interest. 5. The method of claim 1, wherein: receiving the identifying information about the item of interest comprises receiving an image of the item of interest that is captured by a camera of the electronic device; and using the identifying information to identify a candidate item that corresponds to the item of interest comprises: processing the image to extract data from a label or code on the item of interest, and comparing the extracted data to the candidate items in the database to identify a candidate item that corresponds to the item of interest. 6. The method of claim 5, further comprising, by a user interface of the electronic device, before receiving the identifying information about the item of interest, prompting the person to use the electronic device to capture the image of the item of interest so that the image includes the identifying information. 7. The method of claim 1, wherein processing the retrieved characteristics with the user profile to generate the predicted rating comprises: analyzing dependency patterns in one or more preference models in the user profile; and using the dependency patterns to generate the predicted rating. 8. The method of claim 7, wherein analyzing the dependency patterns comprises: analyzing consistent patterns of dependency in the one or more preference models and identifying a representative rating based on the consistent patterns; and using the representative rating as the predicted rating. 9. The method of claim 7, wherein analyzing the dependency patterns comprises: analyzing contrasting or polarizing patterns of dependency in at least one of the preference models; processing values of characteristics of the identified candidate item in the at least one preference model having contrasting or polarizing patterns of dependency to yield a result; and using the result as the predicted rating. 10. The method of claim 1, wherein processing the retrieved characteristics with the user profile to generate the predicted rating comprises: determining that no preference model in the user profile can be matched with the characteristics of the identified candidate item; and generating an inconclusive result as the predicted rating. 11. The method of claim 1, wherein processing the retrieved characteristics with the user profile to generate the predicted rating comprises: determining that no preference models in the user profile is sufficiently reflective of how the person would have rated the item; and generating an inconclusive result as the predicted rating. 12. A system for predicting a person's preference for an item, comprising: one or more processors: a database of characteristic values for a plurality of candidate items; a computer-readable memory storing a user profile for a person; and a computer-readable memory containing programming instructions that, when executed, cause one or more of the processors to: receive identifying information about an item of interest; access the database and use the identifying information to identify a candidate item that corresponds to the item of interest and retrieve one or more characteristics of the identified candidate item; process the retrieved characteristics with the user profile to generate a predicted rating for the item of interest for the person; and output the predicted rating. 13. The system of claim 12, wherein the instructions to process the retrieved characteristics with the user profile to generate a predicted rating for the item of interest for the person comprise instructions to: identify one or more characteristics of the item of interest; determine whether the identified characteristics of the item of interest correspond to one or more indicators of preference in the user profile; and based on whether the identified characteristics of the item of interest correspond to one or more indicators of preference, generate a prediction of whether the person is likely to exhibit a preference for the item of interest. 14. The system of claim 12, wherein: the instructions to receive the identifying information about the item of interest comprise instructions to receive an image of the item of interest; and the instructions to use the identifying information to identify a candidate item that corresponds to the item of interest comprise instructions to: process the image to extract data from a label or code on the item of interest, and compare the extracted data to the candidate items in the database to identify a candidate item that corresponds to the item of interest. 15. The system of claim 14, further comprising: a camera; an electronic device user interface; and additional programming instructions that, when executed, cause one or more of the processors to, before receiving the identifying information about the item of interest, cause the user interface to prompt the person to use the camera to capture the image of the item of interest so that the image includes the identifying information. 16. The system of claim 12, wherein the instructions to process the retrieved characteristics with the user profile to generate the predicted rating comprise instructions to: analyze dependency patterns in one or more preference models in the user profile; and use the dependency patterns to generate the predicted rating. 17. The system of claim 16, wherein the instructions to analyze the dependency patterns comprise instructions to: analyze consistent patterns of dependency in the one or more preference models and identify a representative rating based on the consistent patterns; and use the representative rating as the predicted rating. 18. The system of claim 16, wherein the instructions to analyze the dependency patterns comprise instructions to: analyze contrasting or polarizing patterns of dependency in at least one of the preference models; process values of characteristics of the identified candidate item in the at least one preference model having contrasting or polarizing patterns of dependency to yield a result; and use the result as the predicted rating. 19. The system of claim 12, wherein the instructions to process the retrieved characteristics with the user profile to generate the predicted rating comprise instructions to: determine that no preference model in the user profile can be matched with the characteristics of the identified candidate item; and generate an inconclusive result as the predicted rating. 20. The system of claim 12, wherein the instructions to process the retrieved characteristics with the user profile to generate the predicted rating comprise instructions to: determine that no preference models in the user profile is sufficiently reflective of how the person would have rated the item; and generate an inconclusive result as the predicted rating.
