Automatic document classification via content analysis at storage time

摘要

Techniques are disclosed for efficiently and automatically classifying textual documents or files. In some embodiments, the classification process is integrated into or otherwise made part of the storage function, such that when the user initiates a save process for a given file, the file is processed through a classifier prior to (or contemporaneously with) completing the save function. In some such embodiments, textual content of the file is analyzed using natural language processing to identify a main or substantial concept discussed in the file, and one or more corresponding tags are then assigned to that file. Subsequently, the user can access that file based on the one or more tags, for instance, through a user interface that allows the user to select one or more content categories associated with the assigned tags. The files can be text-based, but may include other content as well, such as images, video, and audio.

主权项

1. A computer readable medium having instructions encoded thereon that, when executed by one or more processors, cause a digital content classification process to be carried out, the process comprising:
defining an initial association that exists between (a) one or more tags that represent a first digital content segment and (b) an initial subject matter categorization; providing, to a first user, the first digital content segment and the initial subject matter categorization; receiving, from the first user, a modified subject matter categorization; modifying the initial association to produce a modified association that exists between (a) the one or more tags and (b) the modified subject matter categorization; receiving, from a second user, a second digital content segment that is also represented by the one or more tags; and providing, to the second user, the modified subject matter categorization without providing the initial subject matter categorization to the second user.
