摘要

通过信用评分的发展,个人判断对个人财务状况评估的影响已经大大减少。该系统能够根据申请人的总分来决定,总分是几个因素和指标的组合。在过去的几十年里,信用评分被认为是各种机构评估的重要工具,也能够将整个行业转变为信用评分信号。在该领域进行的大多数研究都考虑到了传统的信用评分,但考虑到我们生活在不断发展的技术世界和新的社交媒体网络的日益出现,这种研究现在已经过时了。这种技术进步不仅为更复杂的信用评分系统铺平了道路,而且从根本上使前几代人毫无用处。值得注意的是,信用评分及其特点在全球范围内被广泛讨论,但考虑到必须考虑的各个方面和模型,迄今为止还没有一个最好的方法被设计或建议。本研究表明,当整体指数正增长时,社交媒体渠道在预测股市走势方面往往表现相对较好。研究还表明,交易天数的增加和释放的大量信号并不一定意味着这些渠道能够或已经将其提供的股票回报计入一个月的时间框架。使用的方法是“CRISP-DM”,由六个步骤组成。主要变量包括6个月的社会和金融变量。在研究中,我们试图利用数据挖掘模型和RFM方法来识别、分析和分类股票信号中的活跃电报信道。这一类选择k-means算法。然后,在每个聚类中,通过EXTRATREECLASSIFIER算法提取社会变量的重要性和通道的性能,并考虑总指标的变化来衡量通道的性能。

Credit Scoring Active Telegram Channels Offering Stock Signals
The impact of personal judgment on the assessment of an individual’s financial situation has been drastically reduced through the development of credit scoring. The systems are capable of deciding based on an applicant’s total score which is a combination of several factors and indicators. Over the past few decades, credit scoring has been considered an essential tool for evaluation in various institutions and has also been able to transform the industry as a Credit Scoring Signals whole. Most of the research conducted in the field has taken into account traditional credit scoring, but considering the ever-evolving technological world that we live in and the increasing emergence of new social media networks, such research has now become obsolete. Such technological advancements have not only paved the way for far more sophisticated credit scoring systems but also essentially rendered the previous generations useless. It should be noted that credit scoring and its features have widely been discussed across the globe but, considering the various aspects and models that have to be taken into account, no one best method has been designed or suggested for it so far. This study shows that social media channels tend to perform relatively well in predicting stock market trends when the overall index is growing positively. The research also illustrates that a higher number of days of activity and a large number of signals released do not necessarily mean that the channels can or have credited their offered stock return on a one-month time frame. The methodology used is "CRISP-DM," which consists of six steps. The main variables include social and financial variables that are examined for six months. In the research, we seek to identify, analyze and categorize active telegram channels in stock signals using the data mining model and the RFM method. The k-means algorithm is selected for this category. Then, in each cluster, the importance of social variables and the performance of the channels are extracted by the EXTRATREECLASSIFIER algorithm, and channel performance is measured by considering the changes in the total index.
