SVFSearch: A Multimodal Knowledge-Intensive Benchmark for Short-Video Frame Search in the Gaming Vertical Domain
Summary
SVFSearch introduces the first open benchmark for short-video frame search specifically within the Chinese gaming domain. This benchmark addresses the challenge of evaluating multimodal large language models (MLLMs) as agent backbones in applications where visual ambiguity and specialized, fast-evolving domain knowledge are critical for answering queries about paused video frames. SVFSearch comprises 5,000 four-choice test examples and 4,198 auxiliary training examples, each derived from a real short-video clip's game scene. To ensure fair and reproducible evaluations, it provides a frozen offline retrieval environment, including a game-domain text corpus, a topic-linked image gallery, and various retrieval interfaces, bypassing reliance on uncontrolled web search APIs. Initial evaluations of direct QA, RAG workflows, and Plan-Act-Replan agents show a significant performance gap: the best open-source direct-QA model achieved 66.4%, practical agents reached 79.1%, while oracle knowledge scored 95.4%.
Key takeaway
For research scientists developing or deploying multimodal large language models in specialized domains like gaming, you should prioritize benchmarks that simulate real-world knowledge-intensive and visually ambiguous scenarios. Your focus should be on improving visual grounding, retrieval quality, and evidence-grounded reasoning, as current agentic models still exhibit a substantial performance gap compared to oracle knowledge, indicating significant room for advancement in tool-use and reasoning behaviors.
