## Dataset Creation

### Curation Rationale

Originally, the dataset was conceived for the [In-class Kaggle Competition](https://www.kaggle.com/c/wisesight-sentiment/) at Chulalongkorn university by [Ekapol Chuangsuwanich](https://www.cp.eng.chula.ac.th/en/about/faculty/ekapolc/) (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.](https://github.com/wisesight/)

### Personal and Sensitive Information

- We trying 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
