Data characteristics and preprocessing

This corpus does not claim to be a statistically representative sample of the Thai language register.

General information:

• Size: 26,737 messages.
• Language: Central Thai.
• Style: Informal and conversational, with some news headlines and advertisements.

Data coverage:

• Time period: Approximately 2016 to early 2019, with a small amount from other periods.
• Domains: Mixed, with a majority focusing on consumer products and services (restaurants, cosmetics, drinks, cars, hotels). Some current affairs topics are also included.

Privacy:

• Messages were collected from publicly available online sources only (websites, blogs, social network sites).
• For Facebook data, this includes public comments on public pages.
• The dataset does not contain private/protected messages or messages from groups, chats, and inboxes.
• Personally identifiable information has been removed or masked.

Data alterations and modifications:

• A large portion of messages are not in their original form:
  • Usernames and non-public figure names are removed.
  • Phone numbers are masked (e.g., 088-888-8888, 09-9999-9999, 0-2222-2222).
  • Duplicated, leading, and trailing whitespaces are removed.
  • Other punctuations, symbols, and emojis are retained.
  • Misspellings remain uncorrected.
• Messages exceeding 2,000 characters or non-Thai messages are removed.
• Duplicate messages (exact matches) are removed.

• Explore additional data characteristics using this notebook.

Annotation methodology

• Sentiment values are assigned by human annotators.
• A human annotator put his/her best effort to assign just one label, out of four, to a message.
• A message can be ambiguous. When possible, the judgement will be based solely on the text itself.
  • In some situation, like when the context is missing, the annotator may have to rely on his/her own world knowledge and just guess.
  • In some cases, the human annotator may have access to the message's context, like an image. These additional information are not included as part of this corpus.
• Agreement, enjoyment, and satisfaction are positive. Disagreement, sadness, and disappointment are negative.
• Showing interest in a topic or in a product is counted as positive.
  • In this sense, a question about a particular product could have a positive sentiment value, if it shows the interest in the product.
• Saying that other product or service is better is counted as negative.
• General information or news title tend to be counted as neutral.
• For word tokenization annotation methodology, please refer to word-tokenization/README.md.

Corpus file structure

  • train_label.txt: Label for training. Each line is the label corresponding to the same line in train.txt.
  • test.txt - Message for testing (2,674 messages)
  • test_label.txt: Label for testing. Each line is the label corresponding to the same line in test.txt.
