1. A method, in a data processing system, for partial ingestion of content, the method comprising: identifying a set of features that contribute to generating candidate answers for input questions; identifying a set of annotation engines in the ingestion pipeline that contribute to each of the set of features and at least one annotation engine on which the one or more annotation engines depend; generating a sub-pipeline for each set of annotation engines to form a plurality of sub-pipelines of annotation engines; receiving new content to be ingested into a corpus of information; applying the plurality of sub-pipelines of annotation engines against the new content in order of effectiveness, wherein the plurality of sub-pipelines include all annotation engines of an ingestion pipeline and wherein each sub-pipeline within the plurality of sub-pipelines generates one or more intermediate output objects; and providing access to the one or more intermediate output objects, wherein the one or more intermediate output objects represent the partially ingested new content.
