What are the Basic Steps in Thai Sentiment Analysis?

Repustate has a massive corpus of Thai text that has been tagged manually, as the first step towards Thai sentiment analysis. This corpus is then processed by an ML model for high precision in aggregate sentiment scoring. The steps can be laid out as:

  1. Collect a massive, highly varied corpus (collection of texts) of the manually tagged Thai text.
  2. Feed this text into an ML-based algorithm to create an Thai part-of-speech tagger.
  3. Granulate the algorithm for deeper accuracy using NER.
  4. Extract the sentiment score for each aspect, theme, and topic.

Repustate uses Thai Named Entity Recognition (NER) with advanced semantic search to identify brand and business entities in data. No matter how misspelled a word is, the Thai NLP model will reproduce the name in the native script and give accurate name search, transliteration, and identity verification measures. This gives high-accuracy ranked results, based on the linguistic, phonetic, and specific cultural variation patterns of the names.

Should translations be used for Thai sentiment analysis?

Trying to achieve Thai sentiment analysis by using an API that uses translations can yield incorrect results. So, the answer is, no. As your Thai sentiment analysis company, Repustate, uses intricate Thai NLP for higher accuracy in sentiment scoring of your data. This is because translations dilute the nuance of a statement. If a text has multiple topics, sentiments, and themes, as reviews and comments usually do, the aggregate semantic score of the data (+1 for positive, and -1 for negative) will be inaccurate with translations.

กฎไวยากรณ์ของแต่ละภาษาก็แตกต่างกันไป กฎการผันคำกริยา การผันคำนาม-กริยาให้สอดคล้องกัน และการปฏิเสธของแต่ละภาษาก็ไม่เหมือนกัน

ภาษาไทยเป็นภาษาที่มีเอกลักษณ์เฉพาะและต่างจากภาษาอังกฤษในหลายๆ ด้าน การวิเคราะห์ความรู้สึก (Sentiment Analysis) ในภาษาอังกฤษมีเทคนิคและโมเดลทางภาษาของตนเอง หากจะนำเทคนิคและโมเดลดังกล่าวมาใช้ในการวิเคราะห์ความรู้สึกในภาษาไทยก็จะทำให้ได้ผลคลาดเคลื่อนอย่างมาก

Repustate จึงได้พัฒนาเครื่องมือสำหรับภาษาไทยโดยเฉพาะเพื่อช่วยในการวิเคราะห์ความรู้สึกในภาษาไทย เช่น ตัวระบุชนิดของคำในภาษาไทย ตัวจัดกลุ่มคำตามรูปเดิมของภาษาไทย และโมเดลความรู้สึกภาษาไทย


การระบุชนิดของคำในภาษาไทยช่วยให้ Repustate คัดกรองจุดที่อาจมีการแสดงอารมณ์ความรู้สึกภายในข้อความหนึ่งๆ ได้ คำกริยา คำนาม และคำคุณศัพท์จะมีตัวบ่งชี้ที่จำเป็นในการระบุความรู้สึก

หากต้องการสร้างตัวระบุชนิดของคำในภาษาไทยที่ทำงานถูกต้องรวดเร็ว จะต้องมีคลังข้อมูลขนาดยักษ์ของข้อความภาษาไทยที่ได้รับการระบุชนิดของคำไว้โดยมนุษย์ ไม่ใช่ระบบอัตโนมัติ จากนั้นจึงนำข้อความภาษาไทยเหล่านี้ไปป้อนในอัลกอริทึมการเรียนรู้ของเครื่อง (Machine Learning) เพื่อสร้างตัวระบุชนิดของคำในภาษาไทยขึ้นมา

ยิ่งคลังข้อมูลใหญ่เท่าไหร่ และที่สำคัญกว่านั้น ยิ่งคลังข้อมูลหลากหลายเท่าไหร่ การสร้างตัวระบุชนิดของคำภาษาไทยก็ยิ่งมีผลลัพธ์ที่ดีขึ้นเท่านั้น Repustate ได้สร้างคลังข้อมูลข้อความภาษาไทยขนาดยักษ์ขึ้น โดยดึงข้อมูลมาจากหลากหลายแหล่งเพื่อให้ครอบคลุมภาษาไทยในรูปแบบต่างๆ ให้มากที่สุด


Repustate ได้พัฒนาโมเดลภาษาด้านความรู้สึกของภาษาไทยขึ้นมาโดยเฉพาะ เพื่อตรวจจับวลี สำนวน และข้อความต่างๆ ที่ช่วยระบุอารมณ์ความรู้สึกเมื่อเขียนเป็นภาษาไทย ด้วยความเข้าใจในแง่มุมต่างๆ ของไวยากรณ์ไทยซึ่งเป็นเอกลักษณ์และต่างจากภาษาอังกฤษมาก การวิเคราะห์ความรู้สึกในภาษาไทยของ Repustate จึงถูกต้องและรวดเร็วได้เช่นนี้
