背景技术
随着计算机技术的发展,越来越多的技术(大数据、分布式、区块链Blockchain、人工智能等)应用在金融领域,传统金融业正在逐步向金融科技(Fintech)转变,但由于金融行业的安全性、实时性要求,也对技术提出了更高的要求。对于银行的业务系统需要针对企业法人提供贷款,用于企业流动性资金的周转。为了确保企业还款率,降低坏账率,需要对企业法人进行贷后管理,即获取网络中的与各企业相关的企业信息,如企业的公告、融资消息,行政处罚以及裁员公告等。现有企业的贷后管理一般为人工在各大搜索引擎、行业论坛、微博或微信公众号相关企业的相关信息,然后人工判断该企业在未来是否会面临某些风险。因此,现有企业贷后信息的管理不仅操作繁琐而且管理效率低下。

基于上述硬件结构,提出本申请贷后信息的管理方法实施例。
参照图2,图2为本申请贷后信息的管理方法第一实施例的流程示意图,所述贷后信息的管理方法包括:
步骤S10,根据预设企业名称列表,将接收到的企业相关信息按照企业名称进行分类整合,生成各贷后企业对应的企业贷后信息集;
现有企业的贷后管理一般为人工在各大搜索引擎、行业论坛、微博或微信公众号相关企业的相关信息,然后人工判断该企业在未来是否会面临某些风险。然后由专员去各大网站检索企业的企业信息并进行分析的方法效率低下,且每天能处理的企业数量有限,当企业数量增至上万家甚至十万家的时候,专员很难对全部企业完成分析。另外,由专员基于个人的经验知识来对企业面临的风险进行判断,需要专员拥有丰富的背景知识,而且由于主观因素的存在,会使得判断结果容易出现偏差。因此,现有企业贷后信息的管理不仅操作繁琐而且管理效率低下。本实施例中,为了解决上述问题,提供一种贷后信息的管理方法,基于企业事件时间轴确定贷后企业的企业情况,并基于预设事件名称列表预测贷后企业在发生事件时间轴中的事件后的预设时间段内发生风险事件的概率,以便根据该概率对贷后企业进行及时管理,简化企业贷后管理操作,提升管理效率。具体地,所述企业相关信息包括但不限于企业事件信息、企业微博信息或企业论坛信息等,预先将待管理的贷后企业信息罗列在预设企业名称列表中。例如,目前收集国内工商注册的4000万企业名称 列表。然后借助自动化舆情采集技术或者购买舆情数据的方式,将互联网上所有的企业信息采集回来并进行存储,然后将企业相关信息按照企业名称进行分类整合,以使各企业对应的企业相关信息归属于各企业信息,即生成各贷后企业对应的企业贷后信息集。
具体地,步骤S10具体包括:
将所述企业名称列表中的企业名称进行地点前缀删减操作以及公司后缀删减操作;
将删减后的企业名称与预设信息库中的信息进行正则匹配,以在所述信息库中确定所述企业名称列表中的企业名称对应的待处理企业事件信息;
将所述待处理事件企业信息进行切词,得到所述待处理企业事件信息对应的待处理词向量,并将所述待处理词向量相加后得到第一文档向量;
将目标企业事件信息进行切词,得到所述目标企业事件信息对应的目标词向量,并将所述目标词向量相加后得到第二文档向量;
计算所述第一文档向量与所述第二文档向量的余弦距离,并在所述余弦距离大于预设阈值时,将所述待处理企业事件信息作为企业相关信息;
将所述企业相关信息按照所述企业名称进行分类整合,生成各贷后企业对应的企业贷后信息集。
本实施例中,对4000万企业名称列表中的每一个名称,去掉表示地点的前缀(从网络上找到一份公开的全国各省市县区的名称列表,通过字符串匹配的方式来实现过滤),去掉诸如“股份有限公司”,“发展股份有限公司”,“控股股份有限公司”,“集团股份有限公司”这样的后缀,得到每个企业的简称。此外也可以人工对某些企业指定企业简称,增加舆情分类结果的召回率。如“深圳XX银行股份有限公司”经过处理后得到的企业简称是“XX银行”。然后对于任一企业事件信息,通过正则匹配的方式来查找企业事件信息中是否包含某个企业的简称,若不包含则结束该篇企业事件信息的处理;若包含,则对企业事件信息切词,将所有词语的词向量相加后得到企业事件信息文档向量X,同时将匹配到的企业的工商经营范围描述进行切词,即[匹配到的企业][的工商经营范围],也就是通过企业事件信息来匹配企业,然后根据企业名称查询工商经营信息。其中,目标企业事件信息即为企业工商经营信息。将所有词语的词向量相加后得到文档向量Y,若向量X和Y之间的余弦距离大于0.5,则将该企业事件信息分类到这家企业之下。(这里主要是为了解决如下的问题:如果仅用“企业事件信息是否包含企业简称”来对“中国银行”的企业事件信息分类,会得到如下两篇企业事件信息A)中国银行再次入选全球系统重要性银行,成为连续6年入选的金融机构。B)某家中国银行门口的书店,店内的老爷爷特别和 善…..企业事件信息B的内容并非讲中国银行,而只是简单提了一次,把企业事件信息B划分在中国银行下是不合适的。结合工商银行的工商经营范围信息,会发现企业事件信息A和其经营范围都会提到“银行”,“金融”一类的词汇(语义上相近),通过词向量计算得到的文档向量之间的距离也是相近的。反观企业事件信息B,其用词分布和工商经营范围的描述必然存在差异,因此文档向量之间的距离也是较远的。由此,将将企业相关信息按照企业名称进行分类整合,生成各贷后企业对应的企业贷后信息集。
步骤S20,根据预设事件名称列表、所述企业贷后信息集中的企业事件信息以及企业事件信息对应的发生时间点,生成所述各贷后企业对应的企业事件时间轴;
本实施例中,针对每家企业,生成该企业在时间轴上的大事记,用一个企业事件信息,如三元组事件来表示某个时间点上发生的事件,即企业简称,事件名称,事件发生时间。事件名称列表如下表所示:
Figure PCTCN2020126225-appb-000001
每个三级事件都有相应的正则规则表达。将每篇企业事件信息的标题依次与所有三级 事件的正则规则表达进行匹配,若没有命中规则则跳过,若命中规则,则将该企业事件信息所属企业的企业简称,命中的三级事件名称以及企业事件信息发布时间组合成一个三元组并输出。由此,按照事件发生时间点由先到后的顺序,依次归纳出各贷后企业对应的企业事件信息,生成各贷后企业对应的企业事件时间轴。具体实施例中,还可以不用对完整的4000万企业做处理,而是仅针对部分企业生成企业事件时间轴,然后在这小部分企业事件信息集上计算事件转移概率矩阵。
步骤S30,根据所述事件名称列表以及所述企业事件时间轴,计算所述各贷后企业在预设时间段内的发生风险事件的概率,并根据所述各贷后企业发生风险事件的概率,对所述各贷后企业执行相应的贷后管理操作。
本实施例中,预先在事件名称列表中指定具有风险的事件列表,如“高管离职”、“公司裁员”、“股东撤资”、“退市”、“停牌”、“拖欠贷款”、“资金链断裂”、“现金流紧张”、“公司倒闭”、“公司注销”,“破产重组”、“监管停牌”等。然后获取待处理企业在预设时间段内,如最近12个月内的三元组事件,将各个三元组事件依次作为事件A,将事件名称列表中指定的风险事件列表中的事件依次作为事件B,计算P(B|A,3)、P(B|A,6)、P(B|A,12),即发生事件A后3个月内发生事件B的概率、发生事件A后6个月内发生事件B的概率、发生事件A后12个月内发生事件B的概率。若存在某个风险事件发生的条件概率大于0.5,则预示该企业在未来存在一定的风险,贷款发放银行可以执行相应的贷后管理操作,如终止贷款发放等。具体地,所述步骤S30之前,还包括:根据用户操作触发的风险事件设定指令时,在所述事件名称列表中将所述风险事件设定指令中的事件添加风险事件标识,以在所述事件名称列表中指定具有风险的风险事件。
本实施例提供一种贷后信息的管理方法,通过根据预设企业名称列表,将接收到的企业相关信息按照企业名称进行分类整合,生成各贷后企业对应的企业贷后信息集;根据预设事件名称列表、所述企业贷后信息集中的企业事件信息以及企业事件信息对应的发生时间点,生成所述各贷后企业对应的企业事件时间轴;根据所述事件名称列表以及所述企业事件时间轴,计算所述各贷后企业在预设时间段内的发生风险事件的概率,并根据所述各贷后企业发生风险事件的概率,对所述各贷后企业执行相应的贷后管理操作。通过上述方式,本申请基于企业事件时间轴确定贷后企业的企业情况,并基于预设事件名称列表预测贷后企业在发生事件时间轴中的事件后的预设时间段内发生风险事件的概率,以便根据该概率对贷后企业进行及时管理,简化企业贷后管理操作,提升管理效率,解决了现有企业 贷后管理不仅操作繁琐而且管理效率低下的技术问题。
进一步地,基于本申请贷后信息的管理方法第一实施例,提出本申请贷后信息的管理方法第二实施例。
在本实施例中,所述步骤S20具体包括:
将所述企业事件信息中的事件标题与所述事件名称列表中的三级事件对应的正则规则表达进行匹配,判断所述企业事件信息是否命中所述三级事件对应的正则规则表达;
若所述企业事件信息命中所述三级事件对应的正则规则表达,则将所述企业事件信息所属企业的企业名称、命中的三级事件名称以及所述企业时间信息对应的发生时间点,组合生成一个三元组事件;
根据所述各贷后企业对应的三元组事件以及所述三元组事件对应的发生时间点,生成所述各贷后企业对应的企业事件时间轴。
若所述企业事件信息未命中所述三级事件对应的正则规则表达,则将所述企业事件信息标记为待删除事件信息,并在所述企业贷后事件集中删除所述待删除事件信息。
本实施例中,通过三元组事件来表示某个时间点上发生的事件,即企业简称,事件名称,事件发生时间。每个三级事件都有相应的正则规则表达。然后将每篇企业事件信息的标题依次与所有三级事件的正则规则表达进行匹配,若没有命中规则,则将所述企业事件信息标记为待删除事件信息,并在所述企业贷后事件集中删除所述待删除事件信息,即跳过该企业事件信息的添加。若命中规则,则将该企业事件信息所属企业的企业简称,命中的三级事件名称以及企业事件信息发布时间组合成一个三元组并输出。然后将该三元组时间添加至对应企业的企业事件时间轴中,该事件时间轴按照事件发生时间点由先到后的顺序,归纳出该企业所有发生的企业事件信息。
进一步地,所述若所述企业事件信息命中所述三级事件对应的正则规则表达,则将所述企业事件信息所属企业的企业名称、命中的三级事件名称以及所述企业时间信息对应的发生时间点,组合生成一个三元组事件的步骤之后,还包括:
判断所述各贷后企业对应的三元组事件中是否存在待合并事件,其中,所述待合并事件为事件标题相同的两个或多个三元组事件且所述两个或多个三元组事件对应的发生时间点属于预设时间间隔内;
若所述各贷后企业对应的三元组事件中存在待合并事件,则将所述待合并事件中的两个或多个三元组事件合并为一个三元组事件;
在所述两个或多个三元组事件对应的发生时间点中获取最早时间点,作为合并后的三 元组事件对应的发生时间点。
本实施例中,对每个企业下的三元组事件进行合并。若一家企业在连续多天内,或者间断不超过一周的时间内均有同一个三级事件的三元组,则将这些三元组合并为一个三元组,三元组中的事件发生时间取时间最早的一个值。比如在2019-03-01日有25篇报道XX银行获奖的企业事件信息,在2019-03-02日有13篇报道XX银行获奖的企业事件信息,在2019-03-05日有6篇报道XX银行获奖的企业事件信息,然后在2019-06-01日有18篇报道XX银行获奖的企业事件信息,简单分析可以得出,3月份1日,2日以及5日报道的获奖企业事件信息很大概率都是在报道同一个获奖企业事件信息,所以可以将其合并为一个事件三元组(XX银行,获奖,2019-03-01),而6月1日的报道和3月份的时间间隔较久,大概率是在报道XX银行另外一个获奖企业事件信息,所以不能和3月份的三元组合并。
进一步地,基于本申请贷后信息的管理方法第二实施例,提出本申请贷后信息的管理方法第三实施例。
在本实施例中,所述步骤S30具体包括:
将所述企业事件时间轴中的企业事件信息依次作为第一事件信息,并将所述事件名称列表中的风险事件依次作为第二事件信息;
根据预设事件转移概率,计算所述企业事件时间轴所属企业在所述第一事件信息后的对应时间内发生第二事件信息的概率,作为所述企业事件时间轴所属企业发生风险事件的概率;
依次计算所述各贷后企业发生风险事件的概率,并根据所述各贷后企业发生风险事件的概率,对所述各贷后企业执行相应的贷后管理操作。
本实施例中,获取待处理企业在预设时间段内,如最近12个月内的三元组事件,将各个三元组事件依次作为事件A,即第一事件信息,将事件名称列表中指定的风险事件列表中的事件依次作为事件B,即第二事件信息,计算P(B|A,3)、P(B|A,6)、P(B|A,12),即发生事件A后3个月内发生事件B的概率、发生事件A后6个月内发生事件B的概率、发生事件A后12个月内发生事件B的概率。然后计算出各贷后企业对应的企业事件时间轴中各企业事件信息后发生风险事件的概率,并判断各个概率中是否存在大于预设阈值,如0.5,若存在,则预示该企业在未来存在一定的风险,贷款发放银行可以执行相应的贷后管理操作,如终止贷款发放等。
进一步地,所述根据所述事件名称列表以及所述企业事件时间轴,计算所述各贷后企 业在预设时间段内的发生风险事件的概率,并根据所述各贷后企业发生风险事件的概率,对所述各贷后企业执行相应的贷后管理操作的步骤之前,还包括:
根据概率计算公式,计算所述事件名称列表中各个事件之间的事件转移概率,其中,所述概率计算公式为:
P(B|A,t)=N B/(N A+1),其中,P(B|A,t)为在事件A发生后的时间间隔t内发生事件B的概率,A、B为事件名称列表中的两个事件,t为发生A事件之后的时间间隔,N A为事件A相关的三元组个数,N B为在发生事件A后的时间间隔t内发生事件B的次数。
本实施例中,计算全局的事件转移概率,即预先计算所述事件名称列表中各个事件之间的事件转移概率:假设事件抽取模块抽取到的4000万家企业的事件三元组中,与事件A相关的三元组共有N A个,根据三元组中的事件发生时间统计在发生事件A后的t个月内发生事件B的次数为N B,则在事件A发生后t个月内发生事件B的概率可以表示为P(B|A,t)=N B/(N A+1),分母加1的作用是防止为0时出现异常,同时也可以平滑概率值。接下来遍历所有的事件,以及对时间间隔t分别赋值3,6,12,然后计算所有的P(B|A,t)。即优先根据大数据计算出各个事件之间的转移概率,然后针对各贷后企业现有的企业事件时间轴中已发生的企业事件信息预测发生各贷后企业后续发生风险事件的概率。
