Sensitive Word Matching Algorithms in Vivo's Content Review System
Vivo’s Diting content‑review platform employs an Aho‑Corasick automaton to perform fast multi‑pattern matching, extending it with combination‑word and pinyin‑based modes that detect slang, homophones, and multi‑keyword violations, thereby boosting precision and lowering miss rates across its four‑stage moderation pipeline.
