Task: Summarization
Input (English): Deep learning (DL) has in recent years been widely used in natural
 language processing (NLP) applications due to its superior
 performance. However, while natural languages are rich in
 grammatical structure, DL has not been able to explicitly
 represent and enforce such structures. This paper proposes a new
 architecture to bridge this gap by exploiting tensor product
 representations (TPR), a structured neural-symbolic framework
 developed in cognitive science over the past 20 years, with the
 aim of integrating DL with explicit language structures and rules.
 We call it the Tensor Product Generation Network
 (TPGN), and apply it to image captioning. The key
 ideas of TPGN are: 1) unsupervised learning of
role-unbinding vectors of words via a TPR-based deep neural
network, and 2) integration of TPR with typical DL architectures
 including Long Short-Term Memory (LSTM) models. The novelty of our
 approach lies in its ability to generate a sentence and extract
 partial grammatical structure of the sentence by using
 role-unbinding vectors, which are obtained in an unsupervised
 manner. Experimental results demonstrate the effectiveness of the
 proposed approach.
Output (English): This paper is intended to develop a tensor product representation approach for deep-learning-based natural language processinig applications.
