对采集的微信视频号平台带货品类为保健食品类的达人直播视频内容进行转译分析，对达人口播语言内容进行处理、分析，根据达人在直播过程中对预先设置的违规敏感词（比如：无效退款，保险公司保险，安全，安全无毒副作用，毒副作用小，天然，热销，抢购，试用，家庭必备等）违反的次数和频率，依据触发条件规则提出警告或处理。为诸暨市市场监督局管理区域内规范企业微信视频号直播行为，提供数据支持。将采集完成的直播视频进行进行预处理，第一步：基于原始视频文件，以最大10分钟单位对原始视频进行切片。第二步：对于已完成的切片视频，进行视频内容转语音操作。第三步：对于已完成视频转语音操作的切片，进行语音转文本操作。第四步：使用OCR技术对原始视频中抓取的图片进行文字提取操作。第五步：将所得到的文字内容与违法预警关键词库进行匹配。最终运用多标准决策分析模型，对主播在直播过程中出现的违规语句进行分析计算，得出违法预警值和是否预警判断。违法预警值=（违法预警单关键词命中次数*0.25）+（违法预警组合关键词命中次数* 0.3）+（图片识别命中预警组合关键词个数*0.35）+（直播间近一个月历史违规记录数*0.1）通过公式计算出最终违法预警值，违法预警值 ≤1 时，不触发预警提示，违法预警值＞1 时触发违法预警提示。

This work conducts transcription and analysis on the live streaming video content of health food product category livestreaming influencers collected from the WeChat Video Channels platform. The oral speech content of the influencers is processed and analyzed, and warnings or corresponding treatments are proposed based on the frequency and count of violations against pre-set sensitive violation keywords (such as "invalid refund", "insured by insurance company", "safe", "safe and non-toxic side effects", "low toxic and side effects", "natural", "hot-selling", "rush purchase", "trial use", "household essential", etc.) according to the trigger rules. This work provides data support for the Market Supervision Administration of Zhuji City to standardize the live streaming behaviors of enterprises within its jurisdiction on WeChat Video Channels. Preprocessing is conducted on the collected live streaming videos, with the following 5 steps: 1. Slice the original video files into clips with a maximum duration of 10 minutes each; 2. Convert the sliced videos into speech signals; 3. Perform speech-to-text conversion on the speech signals extracted from the sliced videos; 4. Extract text from images captured from the original videos using OCR technology; 5. Match the obtained text content against the violation warning keyword database. Finally, the multi-criteria decision analysis (MCDA) model is used to analyze and calculate the violating statements uttered by the livestreamers during the live streaming process, so as to derive the violation warning score and make the warning determination. The violation warning score is calculated via the following formula: Violation Warning Score = (Number of hits for individual violation warning keywords * 0.25) + (Number of hits for combined violation warning keywords * 0.3) + (Number of combined warning keywords detected via image recognition * 0.35) + (Number of historical violation records of the live streaming room in the past month * 0.1) The final violation warning score is calculated using the above formula. If the final violation warning score ≤ 1, no warning alert will be triggered; if the final violation warning score > 1, a violation warning alert will be triggered.
