US Patent 10268671 Generating parse trees of text segments using neural networks

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating parse trees for input text segments. One of the methods includes obtaining an input text segment comprising a plurality of inputs arranged according to an input order; processing the inputs in the input text segment using an encoder long short term memory (LSTM) neural network to generate a respective encoder hidden state for each input in the input text segment; and processing the respective encoder hidden states for the inputs in the input text segment using an attention-based decoder LSTM neural network to generate a linearized representation of a parse tree for the input text segment.
