This dataset is a part of pyThaiNLP Thai text classification-benchmarks. For the benchmark, we selected the following tags with substantial volume that resemble classifying types of articles※:

• การเมือง - politics
• สิทธิมนุษยชน - human rights
• คุณภาพชีวิต - quality of life
• ต่างประเทศ - international
• สังคม - social
• สิ่งแวดล้อม - environment
• เศรษฐกิจ - economics
• วัฒนธรรม - culture
• แรงงาน - labor
• ความมั่นคง - national security
• ไอซีที - ICT
• การศึกษา - education

We provide 3 benchmarks for 12-topic multi-label classification of prachathai-67k: fastText, LinearSVC, ULMFit, and Multilingual Universal Sentence Encoder . In all cases, we first finetune the embeddings using all data. The data is then split into train, validation and test sets at 70/10/20 split. The benchmark numbers are based on the test set. Performance metrics are macro-averaged accuracy and F1 score. See classification.ipynb for more information.

※ Note that Prachathai.com is a left-leaning, human-right-focused news site, and thus unusual news labels such as human rights and quality of life.
