Abstract: Methods and systems are disclosed for creating and linking a series of interfaces configured to display information and receive confirmation of classifications made by a natural language modeling engine to improve organization of a collection of documents into an hierarchical structure. In some embodiments, the interfaces may display to an annotator a plurality of labels of potential classifications for a document as identified by a natural language modeling engine, collect annotated responses from the annotator, aggregate the annotated responses across other annotators, analyze the accuracy of the natural language modeling engine based on the aggregated annotated responses, and predict accuracies of the natural language modeling engine's classifications of the documents.

Abstract: A process for producing solid particles by drying a spray of liquid droplets. The droplets are formed by projecting a liquid formulation as a plurality of jets J (FIG. 6) in such a way that each jet breaks up into droplets of narrow size distribution. Prior to the onset of coalescence the droplets are contacted with a gas flow (G) which is arranged to reduce coalescence by disrupting slip streaming of the droplets and/or accelerating the droplets.
