13. The computer-readable storage medium of claim 12 , wherein the translation likelihood factors comprise characteristics of an author of the potential snippet and/or characteristics of an expected audience of the potential snippet.
12. A computer-readable storage medium storing instructions that, when executed by a computing system, cause the computing system to perform operations for pre-translation of snippets, the operations comprising: receiving a potential snippet; computing a pre-translation score for the potential snippet based on a selection of translation likelihood factors for the potential snippet, wherein the selected translation likelihood factors are associated with corresponding values, the corresponding values computed as an estimation of an effect the corresponding translation likelihood factor will have on an amount of translations or time of translation of the potential snippet; and determining that the pre-translation score is above a threshold; in response to determining that the pre-translation score is above the threshold, performing a translation of the potential snippet.
