Title
Chinese Textual Sentiment Analysis: Datasets, Resources and Tools
Organizer
Lun-Wei Ku Assistant Research Fellow, Academia Sinica
Wei-Fan Chen Research Assistant, Academia Sinica
Tutorial Description
The rapid accumulation of data in social media (in million and billion scales) has imposed great challenges in information extraction, knowledge discovery, and data mining, and texts bearing sentiment and opinions are one of the major categories of user generated data in social media. Sentiment analysis is the main technology to quickly capture what people think from these text data, and is a research direction with immediate practical value in ‘big data’ era. Learning such techniques will allow data miners to perform advanced mining tasks considering real sentiment and opinions expressed by users in additional to the statistics calculated from the physical actions (such as viewing or purchasing records) user perform, which facilitates the development of real-world applications. However, the situation that most tools are limited to the English language might stop academic or industrial people from doing research or products which cover a wider scope of data, retrieving information from people who speak different languages, or developing applications for worldwide users.

More specifically, sentiment analysis determines the polarities and strength of the sentiment-bearing expressions, and it has been an important and attractive research area. In the past decade, resources and tools have been developed for sentiment analysis in order to provide subsequent vital applications, such as product reviews, reputation management, call center robots, automatic public survey, etc. However, most of these resources are for the English language. Being the key to the understanding of business and government issues, sentiment analysis resources and tools are required for other major languages, e.g., Chinese.

In this tutorial, audience can learn the skills for retrieving sentiment from texts in another major language, Chinese, to overcome this obstacle. The goal of this tutorial is to introduce the proposed sentiment analysis technologies and datasets in the literature, and give the audience the opportunities to use resources and tools to process Chinese texts from the very basic preprocessing, i.e., word segmentation and part of speech tagging, to sentiment analysis, i.e., applying sentiment dictionaries and obtaining sentiment scores, through step-by-step instructions and a hand-on practice. The basic processing tools are from CKIP Participants can download these resources, use them and solve the problems they encounter in this tutorial.

This tutorial will begin from some background knowledge of sentiment analysis, such as how sentiment are categorized, where to find available corpora and which models are commonly applied, especially for the Chinese language. Then a set of basic Chinese text processing tools for word segmentation, tagging and parsing will be introduced for the preparation of mining sentiment and opinions. After bringing the idea of how to pre-process the Chinese language to the audience, I will describe our work on compositional Chinese sentiment analysis from words to sentences, and an application on social media text (Facebook) as an example. All our involved and recently developed related resources, including Chinese Morphological Dataset, Augmented NTU Sentiment Dictionary (aug-NTUSD), E-hownet with sentiment information, Chinese Opinion Treebank, and the CopeOpi Sentiment Scorer, will also be introduced and distributed in this tutorial. The tutorial will end by a hands-on session of how to use these materials and tools to process Chinese sentiment.
Content Details (Materials)
Below is the summary of the materials that will be covered in this tutorial:
Resources please see [2][3][4][5][6][7][8], and
tools please see [1][2][5][9].
Target audience and prerequisites
  • From which areas do you expect potential participants to come?
    Natural Language Processing, Web Mining, Machine Learning, Statistics, and Social Media Analytics
  • What prior knowledge, if any, do you expect from the audience?
    We do not require the audiences to have any background knowledge on the Chinese language. However, we expect the audience already understand some basic concepts and terminologies on natural language processing and sentiment analysis, such as part of speech tagging and opinion polarity.
  • What will the participants learn?
    The goal of this tutorial is to introduce the materials, resources and tool for Chinese sentiment Analysis. We will also highlight the main research challenges and unsolved issues in these areas, as there are still some room for improvement. Therefore, participants will not only acquire the knowledge and recent advances on Chinese sentiment analysis, but can also get ready for the basic Chinese text processing after this tutorial.
