Automatic Article Commenting: the Task and Dataset
Comments of online articles provide extended views and improve user
engagement. Automatically making comments thus become a valuable functionality
for online forums, intelligent chatbots, etc. This paper proposes the new task
of automatic article commenting, and introduces a large-scale Chinese dataset
with millions of real comments and a human-annotated subset characterizing the
comments' varying quality. Incorporating the human bias of comment quality, we
further develop automatic metrics that generalize a broad set of popular
reference-based metrics and exhibit greatly improved correlations with human
evaluations.Comment: ACL2018; with supplements; Dataset link available in the pape
Gradient-based compressive sensing for noise image and video reconstruction
In this study, a fast gradient-based compressive sensing (FGB-CS) for noise image and video is proposed. Given a noise image or video, the authors first make it sparse by orthogonal transformation, and then reconstruct it by solving a convex optimisation problem with a novel gradient-based method. The main contribution is twofold. Firstly, they deal with the noise signal reconstruction as a convex minimisation problem, and propose a new compressive sensing based on gradient-based method for noise image and video. Secondly, to improve the computational efficiency of gradient-based compressive sensing, they formulate the convex optimisation of noise signal reconstruction under Lipschitz gradient and replace the iteration parameter by the Lipschitz constant. With this strategy, the convergence of our FGB-CS is reduced from O(1/k) to O(1/k2 ). Experimental results indicate that their FGB-CS method is able to achieve better performance than several classical algorithms
Research on the E-commerce Model in Textile Industry
E-commerce will play an important role in textile industry. Yet the proper e-commerce model in textile industry has not been solved up till now. It is necessary to study the model as soon as possible, so that we may get together with the advanced countries
Profile Consistency Identification for Open-domain Dialogue Agents
Maintaining a consistent attribute profile is crucial for dialogue agents to
naturally converse with humans. Existing studies on improving attribute
consistency mainly explored how to incorporate attribute information in the
responses, but few efforts have been made to identify the consistency relations
between response and attribute profile. To facilitate the study of profile
consistency identification, we create a large-scale human-annotated dataset
with over 110K single-turn conversations and their key-value attribute
profiles. Explicit relation between response and profile is manually labeled.
We also propose a key-value structure information enriched BERT model to
identify the profile consistency, and it gained improvements over strong
baselines. Further evaluations on downstream tasks demonstrate that the profile
consistency identification model is conducive for improving dialogue
consistency.Comment: EMNLP2
