Abstract: Methods, and systems for a natural language interface with real-time feedback. One of the methods includes receiving an n-gram of characters; identifying a first prefix token within the n-gram of characters; identifying a plurality of possible interpretations of the n-gram of characters; for each possible interpretation, attaching the first prefix token to a token sequence; removing the first prefix token from the n-gram of characters to produce an n-gram remainder; identifying a second prefix token within the n-gram remainder using a tokenizer; identifying a plurality of remaining possible interpretations based on the first prefix token and the second prefix token; for each remaining possible interpretation attaching the second prefix token to a token sequence; applying grammatical rules to each token sequence to determine that each token sequence is valid; and forwarding interpretation data associated with at least one valid token sequence.
