农产品类拼多多直播带货违法监测预警数据

对采集的拼多多平台带货品类为农产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：100%纯天然，绝对无农药残留，特效治疗，绿色有机，预防疾病，抗癌，抗衰老，政府推荐，无激素，快速生长剂，口感绝佳，品质卓越等）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拼多多直播行为，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 dataset conducts transcription and analysis on collected influencer live stream videos of agricultural product categories on the Pinduoduo platform, and processes and analyzes the oral language content of the influencers. Based on the times and frequency of violations of pre-set sensitive violation keywords (such as: "100% pure and natural", "absolutely no pesticide residues", "specific curative effect", "green organic", "disease prevention", "anti-cancer", "anti-aging", "government recommendation", "no hormones", "rapid growth agents", "excellent taste", "superior quality", etc.) by influencers during live broadcasts, warnings or penalties are issued in accordance with trigger condition rules. This work provides data support for the Zhuji City Market Supervision Administration to standardize the live streaming behavior of enterprises on Pinduoduo within its jurisdiction.

The collected live stream videos undergo the following preprocessing steps:
1. Segment the original video files into clips with a maximum duration of 10 minutes.
2. Extract audio from the segmented videos.
3. Convert the extracted audio to text via speech-to-text (ASR) technology.
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, a multi-criteria decision analysis (MCDA) model is used to analyze and calculate the violative statements made by the streamer during the live broadcast, to derive the violation warning score and make a warning determination.
The violation warning score is calculated as:
Violation Warning Score = (Number of hits for single 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 stream room in the past month * 0.1)
The final violation warning score is calculated using the above formula. If the score ≤ 1, no warning prompt is triggered; if the score > 1, a violation warning prompt is triggered.
