System and method for automatic electronic document identification

摘要

A system and method for automatically identifying an electronic document. The method includes accessing, within an electronic device, an electronic document and extracting text from the electronic document. A signature is then determined based on the text of the electronic document and the signature is communicated over a communication channel. The method further includes receiving an identifier of the electronic document over the communication channel. In one embodiment, the identifier is determined by a server matching the signature against a signature library. The method further includes receiving a bookmark associated with the electronic document.

1. A method for automatically identifying an electronic document, said method comprising:
accessing, within an electronic device, said electronic document local to the electronic device; extracting text from said electronic document; generating, using circuitry, a signature based on said text of said electronic document by calculating a frequency of a term in said text of said electronic document; communicating said signature over a communication channel; receiving an identifier of said electronic document over said communication channel, wherein said identifier is determined by a server matching said signature against a signature library, the identifier being different from the signature, said matching being performed by determining whether an approximation of a cosine similarity value computed using Hamming distance function between said signature and a signature in the signature library is greater than a predetermined threshold; receiving a bookmark associated with said electronic document; and receiving, from the server, a recommendation based on the identifier of said electronic document, the recommendation being specific to the electronic document and different from the electronic document.
