Claim 15:
16. A computer-implemented method comprising:
receiving intent existence training texts comprising intent existence training markers and intent extraction training texts comprising open intent extraction training markers, wherein the intent existence training texts and the intent extraction training texts are not classified to an intent category;
training an intent existence long short-term memory neural network comprising a plurality of long short-term memory units organized bi-directionally in two layers and a soft max pooling layer to determine whether a text input comprises an intent by:
applying the intent existence long short-term memory neural network to a plurality of positive text inputs comprising at least one training intent and a plurality of negative text inputs comprising no training intent to generate training intent predictions; and
comparing the training intent predictions with intent existence training markers to modify parameters of the intent existence long short-term memory neural network; and

training an intent extraction long short-term memory neural network comprising a plurality of long short-term memory units organized bi-directionally in a single layer and a conditional random field layer to extract an intent from the text input by:
applying the intent extraction long short-term memory neural network to dependency parser training data, wherein the dependency parser training data comprises training sentences labeled for verbs and objects generated via a dependency parsing model from unlabeled sentences;
fine-tuning the intent extraction long short-term memory neural network by applying the intent extraction long short-term memory neural network to user-labeled training data comprising a training intent to generate an open intent by extracting a verb and an object from the user-labeled training data; and
comparing the intent comprising the verb and the object with the open intent extraction training markers comprising a training verb and training object to modify parameters of the intent extraction long short-term memory neural network.
