Event Identification as a Decision Process with Non-linear Representation of Text
We propose scale-free Identifier Network(sfIN), a novel model for event
identification in documents. In general, sfIN first encodes a document into
multi-scale memory stacks, then extracts special events via conducting
multi-scale actions, which can be considered as a special type of sequence
labelling. The design of large scale actions makes it more efficient processing
a long document. The whole model is trained with both supervised learning and
reinforcement learning.Comment: 8 pages, 8 figure
LCSTS: A Large Scale Chinese Short Text Summarization Dataset
Automatic text summarization is widely regarded as the highly difficult
problem, partially because of the lack of large text summarization data set.
Due to the great challenge of constructing the large scale summaries for full
text, in this paper, we introduce a large corpus of Chinese short text
summarization dataset constructed from the Chinese microblogging website Sina
Weibo, which is released to the public
{http://icrc.hitsz.edu.cn/Article/show/139.html}. This corpus consists of over
2 million real Chinese short texts with short summaries given by the author of
each text. We also manually tagged the relevance of 10,666 short summaries with
their corresponding short texts. Based on the corpus, we introduce recurrent
neural network for the summary generation and achieve promising results, which
not only shows the usefulness of the proposed corpus for short text
summarization research, but also provides a baseline for further research on
this topic.Comment: Recently, we received feedbacks from Yuya Taguchi from NAIST in Japan
and Qian Chen from USTC of China, that the results in the EMNLP2015 version
seem to be underrated. So we carefully checked our results and find out that
we made a mistake while using the standard ROUGE. Then we re-evaluate all
methods in the paper and get corrected results listed in Table 2 of this
