为什么不是单纯比价 Why this is not only price comparison

便宜但不靠谱,不算便宜。 Cheap is not cheap if it does not arrive as pictured.

图像一致性 Image consistency

对比主图、详情图、买家晒图和社媒帖子,找出同款、换壳和盗图。 Compare hero images, detail photos, buyer photos, and social posts to identify same products, relabels, and stolen images.

AI 图片风险 AI-image risk

如果主图明显是 AI 渲染、材质不合理或细节漂移,先降权,再看买家实拍。 If the listing appears AI-rendered or physically inconsistent, downgrade it and look for real buyer photos.

履约记录 Fulfillment history

把“未按图发货”“缺件”“超时”“拒绝退货”等评价聚合成卖家可靠性分。 Aggregate complaints such as wrong item shipped, missing parts, late delivery, and refund friction into a seller reliability score.

系统应该怎么工作 How the system should work

  1. 抓取商品、评论图、帖子、短视频标题和价格历史。 Ingest listings, review photos, posts, video titles, and price history.
  2. 用图片和文本把“同款”聚成一组,不只按标题搜索。 Cluster same products by image and text, not title search alone.
  3. 估算合理价格区间,区分工厂价、零售价、带货价和虚高券后价。 Estimate fair price bands across factory, retail, influencer, and coupon-inflated pricing.
  4. 给每个卖家生成可信度解释,而不是只给一个分数。 Explain seller reliability instead of only showing a score.
