10. A computer-implemented method for extracting portions of content objects for semi-automated response identifications, the method comprising: detecting a set of assessment content objects for processing, each assessment content object of the set of assessment content objects including content-object data arranged according to a spatial arrangement, each assessment content object of the set of assessment content objects being associated with an identifier corresponding to a student; for each assessment content object of the set of assessment content objects: determining that the assessment content object corresponds to an identifier of a template for a particular assessment, the template identifying a segment-position specification that at least partly defines an area in which an answer for a question is to have been provided; identifying a portion of the content-object data as corresponding to an answer area for the question based on the segment-position specification and the spatial arrangement; extracting the portion of the content-object data; evaluating the portion of the content-object data to identify an answer indicated in the portion of the content-object data; determining an evaluation quality metric reflecting a confidence in the identification of the answer; and determining whether a quality criterion is satisfied based on the evaluation quality metric; identifying multiple portions of content-object data extracted from multiple assessment content objects from the set of assessment content objects, each portion of the multiple portions being associated with a determination that the quality criterion is not satisfied; facilitating a presentation that includes: the multiple portions of content-object data; and a tool that receives external input identifying an answer indicated in one or more portions of the multiple portions; receiving an input corresponding to an identification of an answer indicated in a portion of the one or more portions; and upon receiving the input, storing the answer in association with the identifier of the student associated with the assessment content object from which the portion was extracted.

The method for extracting portions of content objects for semi-automated answer identifications as recited in claim 10 , wherein the presentation does not include identifiers corresponding to the students associated with the multiple assessment content object or any other identifier of the students.
