Abstract

A facility for initiating a purchase is described. The facility receives a text sequence captured by a user from a rendered document using a handheld text capture device. The facility identifies in the received text sequence a reference to a distinguished product. In response to identifying the reference, the facility presents to the user an opportunity to place an order for the established product. If the user accepts the presented opportunity to order the distinct product, the facility orders the distinct product on behalf of the user.

Claims

1. A method, comprising:

receiving, by a system server and from a capture device, text captured by the capture device from a paper form of a published document, the document having a publisher;

identifying, by the system server, the published document and the publisher from the captured text;

retrieving, by the system server and from a repository of digital documents, a digital form of the document;

identifying a first product, by the system server, the first product being related to the captured text or to the digital document;

providing to the capture device, by the system server, a purchase option to purchase the first product from a seller server;

receiving a request to purchase the first product from the capture device and providing the request to the seller server, by the system server;

receiving, by the system server, a purchase notice confirming the purchase from the seller server;

associating, by the system server, the purchase with the document and publisher;

providing confirmation of the purchase to the capture device, by the system server; and

providing a purchase and source notice to the publisher, by the system server, enabling the publisher or an author of the document to obtain compensation for the purchase.

2. The method of claim 1, wherein the text captured by the capture device comprises a reference to the first product and a reference to a second product, and wherein providing the purchase option to purchase the product comprises:

assessing availability of each of the referenced products for purchase, wherein the first product is assessed to be available and the second product is assessed to be unavailable, and

providing an opportunity to purchase the first product without providing an opportunity to purchase the second product.

3. The method of claim 1, wherein providing the purchase option to purchase the first product comprises:

determining terms for purchasing the first product; and

presenting the terms for purchasing the first product.

4. The method of claim 1, wherein providing the purchase option to purchase the first product comprises providing a context menu of actions comprising the purchase option to purchase the first product.

5. The method of claim 1, wherein the first product is purchased from a seller, and wherein the method further comprises collecting a referral fee from the seller in connection with the purchase.

6. The method of claim 5, further comprising retrieving, from a document server, a digital document matching the text captured by the capture device, wherein retrieving the digital document comprises:

identifying the document from which the text was captured;

identifying a source of the identified document; and

initiating payment to the identified source of a portion of the referral fee.

7. The method of claim 6, wherein the identified source is a publisher.

8. The method of claim 6, wherein the identified source is an author.

9. The method of claim 1, wherein identifying the first product comprises:

identifying one or more non-extraneous text fragments in the text captured by the capture device;

accessing a data repository that includes a mapping between words or phrases and products; and

determining that at least one of the text fragments corresponds to a word or phrase associated with the first product.

10. The method of claim 9, wherein identifying one or more non-extraneous text fragments comprises an action selected from the group consisting of (i) stripping stop words, (ii) keeping text that appears within quotes, (iii) keeping proper nouns, (iv) keeping capitalized words, and (v) stripping words from the start and the end of the captured text if their frequency of usage meets or exceeds a predetermined threshold value.

11. The method of claim 1, further comprising:

storing, by the system server and in a user-specific log, information comprising a first identifier of the first product; and

receiving, by the system server and from the capture device, a request to access the user-specific log;

wherein the request to purchase the first product occurs after the request to access the user-specific log.

12. A non-transitory computer readable medium containing computer executable instructions that, when executed by one or more servers, cause the one or more servers to perform operations comprising:

receiving text captured by a capture device from a paper form of a published document, the document having a publisher;

identifying the published document and the publisher from the captured text;

retrieving from a repository of digital documents, a digital form of the published document;

identifying a first product, the first product being related to the captured text or to the digital document;

providing to the capture device a purchase option to purchase the first product from a seller server;

receiving a request to purchase the first product from the capture device and providing the request to the seller server;

receiving a purchase notice confirming the purchase from the seller server;

associating the purchase with the document and publisher;

providing confirmation of the purchase to the capture device; and

providing a purchase and source notice to the publisher, enabling the publisher or an author of the document to obtain compensation for the purchase.

13. The non-transitory computer readable medium of claim 12, wherein the text captured by the capture device comprises a reference to the first product and a reference to a second product, and wherein providing the purchase option to purchase the product comprises:

assessing availability of each of the referenced products for purchase, wherein the first product is assessed to be available and the second product is assessed to be unavailable, and

providing an opportunity to purchase the first product without providing an opportunity to purchase the second product.

14. The non-transitory computer readable medium of claim 12, wherein providing the purchase option to purchase the first product comprises:
