Dataset Creation

Curation Rationale

Originally, the dataset was conceived for the In-class Kaggle Competition at Chulalongkorn university by Ekapol Chuangsuwanich (Faculty of Engineering, Chulalongkorn University). It has since become one of the benchmarks for sentiment analysis in Thai.

Source Data

Initial Data Collection and Normalization

  • Style: Informal and conversational. With some news headlines and advertisement.
  • Time period: Around 2016 to early 2019. With small amount from other period.
  • Domains: Mixed. Majority are consumer products and services (restaurants, cosmetics, drinks, car, hotels), with some current affairs.
  • Privacy:
    • Only messages that made available to the public on the internet (websites, blogs, social network sites).
    • For Facebook, this means the public comments (everyone can see) that made on a public page.
    • Private/protected messages and messages in groups, chat, and inbox are not included.
    • Usernames and non-public figure names are removed
    • Phone numbers are masked (e.g. 088-888-8888, 09-9999-9999, 0-2222-2222)
    • If you see any personal data still remain in the set, please tell us - so we can remove them.
  • Alternations and modifications:
    • Keep in mind that this corpus does not statistically represent anything in the language register.
    • Large amount of messages are not in their original form. Personal data are removed or masked.
    • Duplicated, leading, and trailing whitespaces are removed. Other punctuations, symbols, and emojis are kept intact.
    • (Mis)spellings are kept intact.
    • Messages longer than 2,000 characters are removed.
    • Long non-Thai messages are removed. Duplicated message (exact match) are removed.

Who are the source language producers?

Social media users in Thailand

Annotations

Annotation process

  • 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.
  • 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 has 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.

Who are the annotators?

Outsourced annotators hired by Wisesight (Thailand) Co., Ltd.

Personal and Sensitive Information

  • The authors tried to exclude any known personally identifiable information from this data set.
  • Usernames and non-public figure names are removed
  • Phone numbers are masked (e.g. 088-888-8888, 09-9999-9999, 0-2222-2222)
  • If you see any personal data still remain in the set, please tell us - so we can remove them.

Considerations for Using the Data

Social Impact of Dataset

  • wisesight_sentiment is the first and one of the few open datasets for sentiment analysis of social media data in Thai
  • There are risks of personal information that escape the anonymization process

Discussion of Biases

  • 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 an access to the message's context, like an image. These additional information are not included as part of this corpus.

Other Known Limitations

  • The labels are imbalanced; over half of the texts are neu (neutral) whereas there are very few q (question).
  • Misspellings in social media texts make word tokenization process for Thai difficult, thus impacting the model performance
