This article walks through the fundamentals of compiler front‑end development, covering lexical analysis, parsing, and semantic analysis, and provides hands‑on Antlr examples for Java code to illustrate each stage.
This article introduces the fundamentals of compiler front‑end development, covering lexical analysis with finite automata, syntax analysis using context‑free grammars and parsing strategies, and semantic analysis concepts, while providing practical Antlr examples for Java code tokenization, parsing, and semantic checks.
This article provides a comprehensive overview of natural language processing fundamentals, covering the challenges of language modeling, N‑gram and Markov assumptions, smoothing techniques such as discounting and add‑one, evaluation via perplexity, basic tasks like Chinese word segmentation, subword tokenization, POS tagging, syntactic and semantic parsing, and a range of downstream applications including information extraction, sentiment analysis, question answering, machine translation, and dialogue systems.
This article explores how analyzing speech acts—such as inquiries, commands, and expressions—within user utterances can reveal semantic focus points that guide robots in inferring appropriate emotional responses, highlighting classification methods, high‑frequency examples, and a configurable formula for emotion generation in AI dialogue systems.
JD.com's technical architecture team partnered with product teams to leverage the Euler knowledge computing platform and product knowledge graph to enhance the e-commerce review ecosystem, improving user experience in UGC communities through intelligent content management.
This article details Suning's globally distributed search platform, covering its AI‑powered segmentation, ranking, no‑result handling, and the underlying distributed system architecture that enables rapid processing of millions of e‑commerce items.
In a June 28 presentation at Baidu’s 51st Technology Salon, senior NLP researcher Zhao Shiqi showcased Baidu Kaoba—a conversational search tool for college admissions—illustrating how inference‑based rewriting, ellipsis completion, concept clarification and interactive generation enable deep, domain‑specific semantic understanding that he predicts will power future internet services.
