下面结合附图,对本申请的一些实施方式作详细说明。在不冲突的情况下,下述的实施例及实施例中的特征可以相互组合。
请参阅图1,图1是本申请实施例提供的一种文本分类模型的训练方法的示意流程图。该文本分类模型的训练方法是基于卷积神经网络进行模型训练得到的,当然也可以通过其他网络进行训练得到。
需要说明的是,在本实施例中,文本分类模型为TextCNN文本分类模型,TextCNN将卷积神经网络CNN应用到文本分类任务,利用多个不同尺寸的卷积核来抽取文本的局部特征,将文本转换成一个固定维度的特征向量,并基于此特征向量训练一个分类器。由于法律文书的表述模式比较明显,适合采用这种浅层文本分类模型。
如图1所示,该文本分类模型的训练方法,具体包括:步骤S101至步骤S103。
S101、获取第一资产关键句,所述第一资产关键句为包括资产关键词的句子。
其中,第一资产关键句是指包括资产关键词的句子。其中,资产关键词可以是楼房、房产、房地产、房屋、住房、保证、债券、存款等。选取法律文书中包括资产关键词的句子,并将其作为第一资产关键句,用于训练文本分类模型。
S102、根据资产分类类别对应的类别标识对所述第一资产关键句进行标记,以构建样本数据。
具体地,资产分类类别可以包括2大类,分别为资产类别和非资产类别,其中,资产类别又包括5个小类,具体为房产、土地、车辆、存款、借款、担保。在具体实施过程中,样本数据的数量可以为2万条,并且房产:土地:车辆:存款:借款:担保:非资产类别的比例可以为2:1:1:1:2:2:1。
具体地,根据资产分类类别对应的类别标识对所述第一资产关键句进行标记,对第一资产关键句按照类别进行分类,从而按照分类类别提取第一资产关键句构建样本数据。在具体实施过程中,可以按照资产类别和非资产类别的比例进行提取。
S103、基于卷积神经网络,根据所述样本数据进行模型训练和验证以得到文本分类模型,并将所述文本分类模型作为预先训练的文本分类模型。
在具体实施过程中,在对样本数据进行模型训练验证之前,还可以包括:按照预设比例对所述样本数据进行划分,以获得训练集和验证集。训练集用于基于卷积神经网络进行模型训练以得到文本分类模型,验证集用于对得到的文本分类模型进行准确性的验证。其中,训练集和验证集的比例可以为7:3,并且,训练集和验证集中各资产类别和非资产类别的比例与样本数据中的比例相同。
具体地,使用构建的样本数据,通过卷积神经网络进行文本分类模型训练,利用训练集进行文本分类模型训练,利用验证集对训练得到的文本分类模型进行验证,最终得到文本分类模型。
上述实施例提供的训练方法,通过获取第一资产关键句,然后根据资产分类类别对第一资产关键句进行分类,以得到样本数据;最后基于卷积神经网络,根据构建的样本数据进行模型训练,以得到文本分类模型。使得所述文本分类模型能够应用于资产信息识别方法中,由此提高资产信息识别的准确度和通用性。
请参阅图2,图2是本申请实施例提供的一种实体识别模型的训练方法的示意流程图。该实体识别模型的训练方法是基于长短期记忆网络进行模型训练得到的,当然也可以通过其他网络进行训练得到。
需要说明的是,在本实施例中,实体识别模型为BiLSTM+CRF实体识别模型,BiLSTM使用双向的长短期记忆网络得到每个字符在各类实体标签上的得分,CRF从训练数据中学习这些实体标签的约束条件,最终获得每个字符的实体标签,实现实体识别。
如图1所示,该实体识别模型的训练方法,具体包括:步骤S201至步骤S203。
S201、获取第二资产关键句,所述第二资产关键句为包括资产关键词、资产属性和资产所有人的句子。
其中,第二资产关键句是指包括资产关键词、资产属性和资产所有人的句子。其中,资产属性可以是动产、不动产等,资产所有人是指资产的所有权人。
在具体实施过程中,第二资产关键句中所包括的资产属性,可以是直接体现在句子内的,也可以是根据句子中所包括的资产关键词所进行判断的。
例如第二资产关键句可以为“原告花费600万元从被告处购买了一处不动产,该不动产为位于上海市松江区的一处房产。”还可以为“原告花费600万元从被告处购买了一处房产。”
S202、对所述资产关键词、资产属性和资产所有人分别进行标注,以构建样本数据。
具体地,可以采用BIO标注集对资产关键词、资产属性和资产所有人进行标注,以B-实体标签名表示实体首字,以I-实体标签名表示实体非首字,以 O表示非实体部分。在标注完成后,以标注后的资产关键词、资产属性和资产所有人数据构建样本数据。
S203、基于长短期记忆网络,根据所述样本数据进行模型训练和验证以得到实体识别模型,并将所述实体识别模型作为预先训练的实体识别模型。
在具体实施过程中,在对样本数据进行模型训练验证之前,还可以包括:按照预设比例对所述样本数据进行划分,以获得训练集和验证集。训练集用于基于长短期记忆网络进行模型训练以得到实体识别模型,验证集用于对得到的实体识别模型进行准确性的验证。其中,训练集和验证集的比例可以为7:3。
具体地,使用构建的样本数据,通过长短期记忆网络进行实体识别模型训练,利用训练集进行实体识别模型训练,利用验证集对训练得到的实体识别模型进行验证,最终得到实体识别模型。
上述实施例提供的训练方法,通过获取第二资产关键句,然后对第二资产关键句中的资产关键词、资产属性和资产所有人进行标注,以构建样本数据;最后基于长短期记忆网络根据构建的样本数据进行模型训练,以得到实体识别模型,并使得所述实体识别模型能够应用于资产信息识别方法中,由此提高资产信息识别的准确度和通用性。
需要说明的是,由于资产信息识别方法可以应用于终端或服务器中,因此需要将训练好的文本分类模型和实体识别模型保存在终端或服务器中。其中,该终端可以是手机、平板电脑、笔记本电脑、台式电脑、个人数字助理和穿戴式设备等电子设备;服务器可以为独立的服务器,也可以为服务器集群。
如果是应用于终端中,为了保证该终端的正常运行以及快速识别检测出运动目标的类别,还需要对训练得到的文本分类模型和实体识别模型进行压缩处理,将压缩处理后的模型保存在终端。
其中,该压缩处理具体包括对文本分类模型和实体识别模型进行剪枝处理、量化处理和哈夫曼编码处理等,以减小文本分类模型和实体识别模型的大小,进而方便保存在容量较小的终端中。
请参阅图3,图3是本申请的实施例提供的一种资产信息识别方法的示意流程图。该资产信息识别方法可以应用在终端或服务器中,以对法律文书中的资产信息进行识别和提取。
如图3所示,该资产信息识别方法,具体包括步骤S301至步骤S304。
S301、获取法律文书并对所述法律文书进行解析,以获得目标段落,所述目标段落包括诉讼参与人段落和事实段落。
具体地,获取到的法律文书的格式可以是PDF格式,也可以是DOC或者DOCX格式。
诉讼参与人段落是指包括原告基本信息的段落和被告基本信息的段落,其中,原告基本信息和被告基本信息均可以包括:姓名、公司名称、住所地、注册地、经营地、性别、出生日期中的一种或多种。
事实段落是指包括审理法院所查明的案由、案件事实等信息的段落。
在一些实施例中,对所述法律文书进行解析,以获得目标段落,具体包括:根据写作关键词对所述法律文书进行匹配以对所述法律文书进行分段,获得目标段落。
具体地,对法律文书进行解析可以是利用写作关键词对法律文书进行解析。写作关键词是指各个类型的法律文书中,对不同段落进行写作时通常会使用的一些关键词,例如:原告、被告、委托代理人、法定代表人、注册地、经营地、原告诉称、经审理查明、本院认为、审理终结等等。在具体实施过程中,可以根据写作关键词建立写作关键词库,从而利用写作关键词库中的写作关键词对法律文书进行解析。
例如,当在法律文书中第一段的起始处匹配到写作关键词“案号”,并在第六段的结尾处匹配到写作关键词“审理终结”时,则确定第二段至第五段均为诉讼参与人段落,并将第二段至第五段作为目标段落;当在法律文书中第八段的起始处匹配到写作关键词“经审理查明”,并在第十一段的起始处匹配到写作关键词“本院认为”时,则确定自第八段至第十段均为事实段落,并将第八段至第十段作为目标段落。
S302、对所述诉讼参与人段落进行信息提取,以获取诉讼参与人信息。
具体地,诉讼参与人信息包括诉讼参与人名称和诉讼参与人对应的庭审地位,其中庭审地位是指诉讼参与人在该案中是被告还是原告。
在一些实施例中,为了提高获取诉讼参与人信息的效率,请参阅图4,步骤S302具体包括:步骤S302a和步骤S302b。
S302a、根据名称关键词在所述诉讼参与人段落中进行匹配,以获得与所述名称关键词相匹配的目标句子。
具体地,名称关键词是指用于指代具体名词或人物的代词,例如,名称关键词可以包括:原告、委托代理人、法定代表人、被告等等。在获取到诉讼参与人段落后,根据名称关键词在诉讼参与人段落中进行匹配,进而从诉讼参与人段落中确定与名称关键词相匹配的句子,并将该句子作为目标句子。
S302b、利用正则表达式从所述目标句子中获取诉讼参与人名称和庭审地位,将所述诉讼参与人名称和庭审地位作为诉讼参与人信息。
具体地,正则表达式可以利用预先给定的组成规则从字符串中提取子字符串,使得能够查找文档内特定的文本。
例如,当目标句子为:“原告:张三,男,1970年5月12日生,住xx街xx巷xx。”时,利用正则表达式:^原告:*$,在该目标句子中获取诉讼参与人名称为:张三,庭审地位为:原告。
首先从诉讼参与人段落中匹配得到具有名称关键词的目标句子,再利用正则表达式在目标句子中提取出诉讼参与人名称和庭审地位,提高了在诉讼参与人段落中提取诉讼参与人信息的速度和效率。
S303、根据所述诉讼参与人信息对所述事实段落进行指代消解,以获得消解后的事实段落。
具体地,指代消解是指在段落中确定段落中所使用的代词指向哪个名词,并将所使用的代词替换为对应的名词。根据诉讼参与人信息对事实段落进行指代消解,以得到完整的事实段落。
在一些实施例中,请参阅图5,对事实段落进行指代消解具体包括步骤S303a和步骤S303b。
S303a、建立所述诉讼参与人名称与所述庭审地位之间的对应关系。
具体地,从目标句子中获取到诉讼参与人名称和庭审地位后,建立诉讼参与人名称和其对应的庭审地位之间的对应关系,例如,当目标句子为:“原告:张三,男,1970年5月12日生,住xx街xx巷xx。”时,从该目标句子中获取得到诉讼参与人名称为:张三,庭审地位为:原告,则建立原告与张三之间的对应关系。
S303b、基于所述对应关系对事实段落中的庭审地位代词进行替换,以完成事实段落的指代消解。
具体地,获取到事实段落后,对事实段落中的庭审地位代词进行查找,并基于诉讼参与人名称与庭审地位之间的对应关系,将事实段落中的庭审地位代词进行替换,从而完成对事实段落的指代消解。
例如,当事实段落为“2012年7月,原告、被告签订医学影像打印系统经销合作协议一份,约定被告向原告购买医学影像打印系统及服务,仅限销售给淮安二院。”其中,原告与张三对应,被告与李四对应。
对上述事实段落进行指代消解后,得到的段落为“2012年7月,张三、李四签订医学影像打印系统经销合作协议一份,约定李四向张三购买医学影像打印系统及服务,仅限销售给淮安二院。”
S304、利用预先训练的文本分类模型和实体识别模型对所述消解后的事实段落进行信息提取,以获得资产信息。
具体地,资产信息包括资产所有人、关联方和资产属性。所述资产属性可以是预定义的,例如,动产、不动产等等,关联方可以是与资产所有人具有关联的第三方。
在一些实施例中,为了提高从事实段落中获取资产信息的效率,请参阅图6,步骤S304具体地包括步骤S304a至步骤S304c。
S304a、根据资产关键词在所述消解后的事实段落中进行匹配,以获得与所述资产关键词相匹配的初始资产关键句。
其中,资产关键词可以是人工总结归纳的,资产关键词可以是例如楼房、房产、房地产、房屋、住房、营业房、商住楼、商用楼、大厦、店面、土地使用权、土地、宅基地、用地、车辆、担保、保证、债券、存款等等。根据资产关键词在消解后的事实段落中进行匹配,匹配到包括资产关键词的句子作为初始资产关键句,而匹配不到资产关键词的句子可以直接过滤。
S304b、利用预先训练的文本分类模型对所述初始资产关键句进行过滤,以获得目标资产关键句。
利用预先训练的文本分类模型对初始资产关键句进行过滤,从而过滤掉初始资产关键句中仅包含资产关键词,而不存在资产属性的句子,并将未被文本分类模型过滤掉的初始资产关键句作为目标资产关键句。
S304c、基于预先训练的实体识别模型对所述目标资产关键句进行资产信息的识别,以获得资产所有人、关联方和资产属性。
其中,目标资产关键句为包括资产关键词和资产属性的句子,利用预先训练的实体识别模型,可以得到目标资产关键句中所提到的资产所有人、关联方和资产属性。
上述资产信息识别方法通过对获取到的法律文书进行解析,从而获得诉讼参与人段落和事实段落;然后对诉讼参与人段落进行信息提取,得到诉讼参与人信息;利用诉讼参与人信息对事实段落进行指代消解,从而获得消解后的事实段落;最后利用预先训练的文本分类模型和实体识别模型对消解后的事实段落进行信息提取,从而获得资产信息。通过训练文本分类模型和实体识别模型,在关键词匹配的基础上充分利用句子分类模型和实体识别模型,完成法律文书中资产信息的识别和提取,比传统的规则遍历法更有通用性,能够进行自动识别,并且提高资产信息识别的准确率。
