How Meituan Search 3.0 Leverages LLM Semantic Representations to Boost Ranking

The article details Meituan Search 3.0’s three‑phase journey—validating LLM‑based semantic vectors, rebuilding a systematic representation pipeline with contrastive learning and LoRA, and transferring the model to downstream item ranking—showing how 64‑dimensional cosine similarity features and multi‑scale embeddings consistently improve click, order and NDCG metrics across service‑retail search scenarios.

Complex Semantic Expression Methods in Voice Assistants: NLP Layers, DIS Limitations, and the CMRL Schema

This article explains how voice assistants rely on NLP's three processing layers, examines the shortcomings of the traditional DIS semantic structure, introduces the hierarchical CMRL schema with its six element types, and presents two neural models—copy‑write seq2seq and seq2tree—for accurate semantic parsing of complex commands.

Why Natural Language Understanding Is Difficult: Structure Prediction, Semantic Representation, and Multimodal Context

The article explains that natural language understanding is fundamentally a structure‑prediction problem whose difficulty stems from language innovation, recursion, ambiguity, subjectivity and social factors, and argues that richer semantic representation spaces and multimodal context modeling are needed for true AI comprehension.
