A clausifier and method of extracting clauses for spoken language understanding are disclosed. The method relates to generating a set of clauses from speech utterance text and comprises inserting at least one boundary tag in speech utterance text related to sentence boundaries, inserting at least one edit tag indicating a portion of the speech utterance text to remove, and inserting at least one conjunction tag within the speech utterance text. The result is a set of clauses that may be identified within the speech utterance text according to the inserted at least one boundary tag, at least one edit tag and at least one conjunction tag. The disclosed clausifier comprises a sentence boundary classifier, an edit detector classifier, and a conjunction detector classifier. The clausifier may comprise a single classifier or a plurality of classifiers to perform the steps of identifying sentence boundaries, editing text, and identifying conjunctions within the text. |

1. A system comprising:
a processor; and a computer-readable medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising:
inserting, via a discriminative classification approach independent of an n-gram approach, boundary tags, word by word, into speech utterance text, the boundary tags identifying boundaries selected from a group consisting of phrase boundaries, sentence boundaries, and paragraph boundaries, wherein the discriminative classification approach utilizes syntactic features before and after each word being tagged, to yield boundary marked speech utterance text;thereafter, inserting, via the discriminative classification approach, edit tags in the boundary marked speech utterance text to identify at least one word of a set of duplicated words, to yield edited text and unedited text, wherein each edit tag comprises edit span information indicating how many words to the left of each edit tag to edit;thereafter, identifying coordinating conjunctions within the unedited text based on a conjunction tag, to yield identified coordinating conjunctions, wherein the conjunction tag comprises conjunction span information indicating how many words to the left of the conjunction tag a corresponding conjunction includes; andidentifying clauses in the speech utterance text based on the boundary marked speech utterance text, the edited text, and the identified coordinating conjunctions. |
