RPA实战｜Temu客户评价智能分析！3分钟提取千条关键词，洞察用户心声🚀
客户评价堆积如山，手动分析看花眼？关键词提取全靠人工，效率低下还漏重点？别让宝贵的用户反馈白白浪费！今天分享如何用影刀RPA+AI打造智能评价分析系统，让用户心声一目了然！
一、背景痛点：评价分析的那些"望洋兴叹"
作为Temu卖家，你一定经历过这些让人无奈的场景：
那些让人头疼的时刻：
评价爆炸，新品上线后收到500+评价，逐条阅读到怀疑人生
关键词提取，手动记录高频词汇，Excel统计到手抽筋
情感误判，"物美价廉"看成负面评价，错过产品优化机会
竞品分析，手动对比竞品评价差异，效率低下还抓不住重点
报告整理，每周整理评价分析报告，复制粘贴到眼花缭乱
更扎心的数据现实：
手动分析100条评价：2小时 × 每周5次 =周耗10小时！
人工提取准确率：主观判断，关键词覆盖不全约30%
RPA+AI自动化：3分钟千条分析 + 智能情感判断 =效率提升40倍，准确率95%+
最致命的是，手动分析速度慢、洞察浅，而竞争对手用AI工具实时监控用户反馈，这种信息差就是产品优化的天壤之别！💥
二、解决方案：RPA+AI评价分析黑科技
影刀RPA的数据抓取和AI自然语言处理能力，完美解决了评价分析的核心痛点。我们的设计思路是：
