Abstract: In one embodiment, the method includes receiving one or more characters inputted by a user; calculating a degree of difficulty of a character string, wherein the degree of difficulty is based on the characters inputted by the user, and wherein the characters inputted by the user comprise a portion of the character string; and if the degree of difficulty is equal to or exceeds a pre-determined threshold, then presenting, on a display of the computing device, an auto-suggestion for completing the character string; else, not presenting, on the display of the computing device, the auto-suggestion for completing the character string.

Abstract: In particular embodiments, one or more images associated with a primary user are received. The image(s) may comprise single images, a series of related images, or video frames. In each image, one or more faces are detected and/or tracked. For each face, a set of one or more candidates are selected who may be identified with the face. A candidate score is calculated for each candidate based on a computed measure of affinity of the primary user for a particular candidate, a facial recognition score comparing the candidate to the face, and a geographic proximity of the candidate to the primary user at a time when the one or more images were created. A winning candidate is selected based on the candidate scores.
