Sensitive Word Matching in Vivo's Content Review System: Algorithm Selection and Practical Implementations

The article describes how Vivo's content moderation platform, DiTing, uses algorithm selection—including Aho‑Corasick automaton, combination word matching, and pinyin‑based matching—to efficiently detect sensitive terms in large‑scale text streams, while addressing challenges such as homophones, multi‑character patterns, and performance constraints.

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.
