NLPCC2016-WordSeg-Weibo

NLPCC 2016 微博分词评测项目

##Description of the Task

Word is the fundamental unit in natural language understanding. However, Chinese sentences consists of the continuous Chinese characters without natural delimiters. Therefore, Chinese word segmentation has become the first mission of Chinese natural language processing, which identifies the sequence of words in a sentence and marks the boundaries between words.

Different with the popular used news dataset, we use more informal texts from Sina Weibo. The training and test data consist of micro-blogs from various topics, such as finance, sports, entertainment, and so on.

Each participant will be allowed to submit the three runs: closed track run, semi-open track run and open track run.

  1. In the closed track, participants could only use information found in the provided training data. Information such as externally obtained word counts, part of speech information, or name lists was excluded.
  2. In the semi-open track, participants could use the information extracted from the provided background data in addition to the provided training data. Information such as externally obtained word counts, part of speech information, or name lists was excluded.
  3. In the open track, participants could use the information which should be public and be easily obtained. But it is not allowed to obtain the result by the manual labeling or crowdsourcing way.

Data

The data are collected from Sina Weibo. Both the training and test files are UTF-8 encoded. Besides the training data, we also provide the background data, from which the training and test data are drawn. The purpose of providing the background data is to find the more sophisticated features by the unsupervised way.

Download

The dataset provides a standard training/dev/test split. Specifically, the researchers interested in the dataset should download and fill up this Agreement Form and send the scanned version back to Xipeng Qiu (xpqiu@fudan.edu.cn; Email title: Fudan Micro-blog Dataset data request).

本数据集提供标准的训练集/开发集/测试集分割。如果您在论文中使用了本数据集,请您给我们发一份 使用协议。请签名后扫描,将扫描的协议书发给我们 (邮件地址:xpqiu@fudan.edu.cn; 邮件主题: 复旦微博数据集申请)。

Evaluation Metric

Different with the standard precision, recall, F1-score, we will provide a new measure metric this year. The detailed information can be found in http://aclweb.org/anthology/P/P16/P16-1206.pdf .
