【NLPCC 2020】Call for Participation: Shared Tasks in NLPCC 2020

发布：NLPCC会议

The 9th CCF International Conference on Natural Language Processing and Chinese Computing (NLPCC2020)

Registration Deadline: May 1st, 2020

http://tcci.ccf.org.cn/conference/2020/

The CCF International Conference on Natural Language Processing and Chinese Computing (NLPCC) is the annual conference of CCF TCCI (Technical Committee of Chinese Information, China Computer Federation). The NLPCC conferences have been successfully held in Beijing (2012)，Chongqing (2013), Shenzhen (2014), Nanchang (2015), Kunming (2016), Dalian (2017), Hohhot (2018) and Dunhuang (2019). This year's NLPCC conference will be held in Zhengzhou on October 14-18, 2020.

NLPCC 2020 will follow the NLPCC tradition of holding several shared tasks in natural language processing and Chinese computing. This year’s shared tasks focus on both classical problems and newly emerging problems, including Light Pre-Training Chinese Language Model for NLP Task, Multi-Aspect-based Multi-Sentiment Analysis, and Auto Information Extraction.

Participants from both academia and industry are welcomed. Each group can participate in one or multiple tasks and members in each group can attend the NLPCC conference to present their techniques and results. The participants will be invited to submit papers to the main conference and the accepted papers will appear in the conference proceedings published by Springer LNCS. 

The top 3 participating teams of each task will be certificated by NLPCC and CCF Technical Committee on Chinese Information Technology. If a task has multiple sub-tasks, then only the top 1 participating team of each sub-task will be certificated.

1.  Overview of the Shared Tasks

There are three shared tasks in this year’s NLPCC conference and the detailed description of each task can be found in the task guidelines released. Here we only give a brief overview of each task.

◇ Task 1 - Light Pre-Training Chinese Language Model for NLP Task

The goal of this task is to train a light language model which is still as powerful as the other normal models. Each model will be tested on many different downstream NLP tasks. We would take the number of parameters, accuracy and inference time as the metrics to measure the performance of a model. To meet the challenge of the lack of Chinese corpus, we will provide a big Chinese corpus for this task and will release them for all the researchers later.

◇ Task 2 - Multi-Aspect-based Multi-Sentiment Analysis (MAMS)

In existing aspect-based sentiment analysis (ABSA) datasets, most sentences contain only one aspect or multiple aspects with the same sentiment polarity, which may make ABSA task degenerate to sentence-level sentiment analysis. In NLPCC-2020, we manually annotated a large-scale restaurant review corpus for MAMS, in which each sentence contains at least two different aspects with different sentiment polarities. The MAMS task includes two subtasks: (1) aspect term sentiment analysis (ATSA) that aims to identify the sentiment polarity towards the given aspect terms and (2) aspect category sentiment analysis (ACSA) that aims to identify the sentiment polarity towards the pre-specified aspect categories. We will provide train and development sets to participating teams to build their models.

◇ Task 3 - Auto Information Extraction (AutoIE)

Entity extraction is a fundamental problem in language technology. Most previous works focus on the scenario in which labeled data is provided for interested entities. However, the categories of entities can be hierarchical and cannot be enumerated sometimes. Thus, a generic solution cannot depend on the hypothesis that enough labeled data is provided. This task is to build IE systems with Noise and Incomplete annotations. Specifically, given a list of entities of specific type and an unlabeled corpus containing these entities, the task aims to build an IE system which may recognize and extract the interested entities of given types. The task setting is very practical and thus the proposed solutions may generalize well in real-world applications.
