1. What is NLP and Why is it Crucial?

NLP (Natural Language Processing) is a subfield combining AI, linguistics, and computer science to help machines understand and interact with human language. For chatbots, NLP is essential for interpreting user intent and delivering accurate responses.

2. Challenges in Vietnamese NLP

• Language Complexity: Vietnamese has tonal rules and no clear word delimiters, making tokenization difficult.
• Slang and Typos: Informal expressions and spelling variations are common in user input.
• Context Sensitivity: Vietnamese expressions often rely heavily on context and regional variation.

3. Common NLP Techniques in Chatbots

• Tokenization: Breaking sentences into meaningful units (words).
• POS Tagging: Assigning parts of speech for better syntactic understanding.
• NER: Recognizing entities like names, locations, and dates.
• Intent Classification: Understanding user purpose like “buy”, “ask”, or “complain”.
• Sentiment Analysis: Detecting emotional tone—positive, negative, or neutral.

4. Applications of NLP in Vietnamese AI Chatbots

• Answering FAQs with natural language.
• Understanding complex requests with contextual awareness.
• Generating personalized conversations based on user behavior.
• Self-learning from real user interactions to improve over time.

5. NLP Optimization for Vietnamese Chatbots

• Use Vietnamese-specific models like PhoBERT, VnCoreNLP.
• Combine rule-based methods with AI for better precision.
• Design cleaner input interfaces to minimize user errors.
• Collaborate with local experts such as NKKTech Global for best results.
