图1是本公开实施例中的一种文案生成方法的流程示意图,如图1所示,该方法包括如下步骤:
步骤100:获取商品的第一属性数据。
这里,商品可以表示电商平台或卖家通过互联网进行交易的任意类型的物品;例如,可以是服饰类物品、食品类物品等,还可以是虚拟物品等;本公开实施例对物品的类型不作限制。
本公开实施例中,第一属性数据可以包括商品的属性词和属性;属性词可以指描述商品特征的词语或词组,属性表示与该属性词对应的、且能够与其他属性词的属性形成区分的词;其中,第一属性数据中每个属性数据的数据形式为属性词|属性;例如,一字肩|领型、无袖|袖长、圆领|领型、拼接|流行元素。
在一些实施例中,第一属性数据的来源可以包括以下至少之一:商品标题、商品类目、商品扩展信息。
在一种实施方式中,可以通过对第一属性数据的来源进行分词和词性标注等一系列处理过程,获取到商品的第一属性数据。其中,上述处理过程可以通过序列标注模型进行实现;其实现的过程可以为:首先对输入的商品标题、商品类目或商品扩展信息进行分词处理,得到各个词序列;根据词序列的含义以及上下文内容对各个词序列进行序列标注;这里,各个词序列对应不同的属性词,序列标注的内容对应各个属性词的属性;进而,通过序列标注模型,可以获取到商品的第一属性数据。
在一些实施例中,分词是将连续的字序列按照一定的规范重新组合成词序列的过程,分词处理可以通过分词工具或分词算法进行实现;这里,可以根据实际应用场景进行设置,本公开实施例不作限制;例如,可以是pkuseg分词工具、结巴分词算法等。
在一些实施例中,词性标注可以被称为语法标注或词类消疑,词性标注可以将分词处理得到的词序列的词性按其含义和上下文内容进行标记的文本数据处理技术;其中,词性标注处理可以由人工或特定算法进行实现。
在一种实施方式中,在获取商品的第一属性数据之前,接收用户发送的针对商品的文案生成请求,该文案生成请求中可以包括用户输入的第一属性数据的来源。
在一种实施方式中,可以根据第一属性数据的来源,分别从商品标题、商品类目以 及商品扩展信息中获取的扩展属性数据;再将三种不同来源的属性数据进行合并,得到商品的完整属性数据;根据预设规则对属性数据进行过滤处理,得到符合要求的属性数据,即,商品的第一属性数据。
在一种实施方式中,假设商品类目为:服饰内衣|一级类目、女装|二级类目、连衣裙|三级类目;商品标题为:XX品牌原创设计师女装夏装新款气质中长款不规则挂脖礼服裙子无袖一字肩白色连衣裙XL;对商品标题进行分词和词性标注的结果为:XX|品牌词、原创|风格属性、女装|副产品词、夏装|副产品词、新款|风格属性、气质|风格属性、中长款|样式属性、不规则|样式属性、挂脖|样式属性、礼服|副产品词、裙子|产品词、无袖|样式属性、一字肩|样式属性、白色|颜色属性、连衣裙|产品词、XL|尺码属性。
扩展属性数据:轻熟女|适用人群、涤纶|材质、街拍|风格、25-29周岁|适用年龄、2019年夏季|上市时间、中裙|裙长、拼接|流行元素、高腰|腰型;可以将上述三种不同来源的属性数据进行合并,得到商品的完整属性数据。
通过预设规则过滤后保留的属性数据:服饰内衣|一级类目、女装|二级类目、连衣裙|三级类目、一字肩|样式属性、轻熟女|适用人群、涤纶|材质、街拍|风格、中裙|裙长、拼接|流行元素、高腰|腰型、XX|品牌词、原创|风格属性、夏装|副产品词、气质|风格属性、中长款|样式属性、不规则|样式属性、挂脖|样式属性、礼服|副产品词、裙子|产品词、白色|颜色属性、连衣裙|产品词、圆领|领型。
在一种实施方式中,预设规则可以对商品的部分属性数据进行过滤;这是因为过滤的这部分属性数据对后续商品文案的生成作用不明显,通过进行这部分属性数据的过滤,可以在确保商品文案的准确性的同时提高商品文案的生成效率;这里,预设规则可以由人工基于商品特征制定。
步骤101:基于预先训练的第一文案生成模型,确定商品的第一关键属性数据;第一关键属性数据表示第一属性数据中的部分属性数据。
本公开实施例中,预先对第一文案生成模型进行训练,得到训练完成的第一文案生成模型;在进行文案生成时,将获取到的商品的第一属性数据作为第一文案生成模型的输入数据,第一文案生成模型的输出为商品对应的文案。
本公开实施例中,第一文案生成模型进行文案生成的过程主要包括内容选择和描述生成这两个阶段;其中,内容选择的结果是从商品的第一属性数据确定的第一关键属性数据;第一关键属性数据表示最终输出的文案中要重点描述的内容;描述生成的结果是针对第一关键属性数据生成对应的文案描述。
在一种实施方式中,将商品的第一属性数据“XX|品牌、女装|副产品词、夏装|副产品词、连衣裙|产品词、圆领|领型”输入到第一文案生成模型,如果第一文案生成模型确定商品的第一关键属性数据为“圆领|领型”;第一文案生成模型的输出可以为“衣领为典雅的圆领设计”。
在一些实施例中,第一文案生成模型是通过以下步骤训练得到的:获取商品的历史文案以及第二属性数据;将第二属性数据与历史文案进行匹配,得到第二关键属性数据;将历史文案、第二属性数据以及第二关键属性数据作为训练数据;通过训练数据训练第一文案生成模型,得到训练完成的第一文案生成模型。
在一种实施方式中,第一文案生成模型的训练过程为:将训练数据历史文案、第二属性数据以及第二关键属性数据输入到模型中,利用反向传播算法不断调整模型的网络参数,使得模型根据第二属性数据确定的关键属性数据与第二关键属性数据完全相同;并且根据第二关键属性数据生成的商品文案与历史文案尽可能一致。
在一种实施方式中,历史文案可以表示现有的针对商品进行描述的相关文案,其可以是人工撰写的文案,也可以是从商品文案语料中获取的文案;这里,为了提高商品文案的多样性,可以获取商品的多个历史文案;而多个历史文案的来源可以根据实际应用场景进行设置,本公开实施例不作限制。
本公开实施例中,通过第二属性数据与历史文案的匹配获取商品的第二关键属性数据,作为第一文案生成模型训练的中间数据。其中,商品的第二属性数据的获取与步骤100中第一属性数据的获取方式相同,这里不再累赘。
在一种实施方式中,假设商品的历史文案为“整体的设计为简约风尚,简明的线条勾勒不俗气质,显出知性干练的气质特点。衣领为典雅的圆领设计,简约中显出摩登风。腰部采用拼接设计而成,显出纤细腰肢,修饰美好身材线条”。通过第二属性数据与该历史文案的匹配获取的第二关键属性数据可以为:气质|风格属性、圆领|领型、拼接|流行元素。
在一些实施例中,第一文案生成模型包括:第一解码器和第二解码器,第一解码器用于对第二属性数据进行解码,得到第二关键属性数据;第二解码器用于生成第二关键属性数据对应的文案描述。
这里,第一文案生成模型可以为seq2seq模型,该模型可以包括:编码器、第一解码器和第二解码器;在第一文案生成模型的训练过程中,编码器的输入数据为“属性词|属性”对,对应商品的第二属性数据;采用长短期记忆网络(Long Short-Term Memory, LSTM)作为编码器,对输入数据进行编码,得到隐变量,如公式(1)所示:
h j=LSTM(h j-1,x j)      (1)
公式(1)中,h j表示编码端j时刻的隐变量,h j-1表示编码端j-1时刻的隐变量,x j表示输入数据。
使用第一解码器对商品的第二属性数据进行解码,确定出商品的关键属性数据是否与第二关键属性数据对应;对商品的关键属性数据k i进行解码的过程如公式(2)、(3)、(4)所示:
h i=LSTM(h i-1,k i-1)      (2)
Figure PCTCN2021127421-appb-000001
Figure PCTCN2021127421-appb-000002
其中,h i-1是前一时刻第二属性数据的隐状态。k i-1在训练阶段是当前时刻的第二关键属性数据,在预测阶段是前一时刻解码出的关键属性数据。h i是当前时刻第二关键属性数据的隐状态,c i是当前时刻编码端的注意力上下文向量,
Figure PCTCN2021127421-appb-000003
是当前时刻生成的注意力数据的隐状态,g是一种变换函数。
接着,使用第二解码器解码生成与关键属性数据k i对应的商品文案y。
在一种实施方式中,第一文案生成模型采用联合训练的方式,同时完成第二关键属性数据的选择和商品文案的生成,该模型的目标函数采用最大似然同时考虑了两个阶段的目标,联合目标函数如公式(5)所示:
max∑ Dlog(k|x)+logp(y|x,k)      (5)
其中,x,k,y分别指商品的第二属性数据、商品的第二关键属性数据和商品文案,第一项表示第一解码器解码的目标,第二项表示第二解码器生成文案的目标。
可以看出,在第一文案生成模型训练阶段需要第二属性数据、第二关键属性数据和历史文案;第一文案生成模型预测阶段输入属性数据,输出是预测结果。
在一种实施方式中,第一文案生成模型预测阶段:输入属性数据,即过滤后保留的属性数据:服饰内衣|一级类目、女装|二级类目、连衣裙|三级类目、一字肩|样式属性、轻熟女|适用人群、涤纶|材质、街拍|风格、中裙|裙长、拼接|流行元素、高腰|腰型、XX|品牌词、原创|风格属性、夏装|副产品词、气质|风格属性、中长款|样式属性、不规则| 样式属性、挂脖|样式属性、礼服|副产品词、裙子|产品词、白色|颜色属性、连衣裙|产品词、圆领|领型。
第一解码器解码出关键属性词:气质|风格属性、圆领|领型、拼接|流行元素。
第二解码器生成文案,即,预测结果:整体的设计为简约风尚,简明的线条勾勒不俗气质,显出知性干练的气质特点。衣领为典雅的圆领设计,简约中显出摩登风。腰部采用拼接设计而成,显出纤细腰肢,修饰美好身材线条。
在一些实施例中,通过训练数据训练第一文案生成模型,得到训练完成的第一文案生成模型,包括:使用双注意力机制对第一解码器的网络参数进行调整,并使用覆盖机制对第二解码器的网络参数进行调整,得到训练完成的第一文案生成模型。
本公开实施例中,在对第一文案生成模型训练的过程中,使用双注意力机制和覆盖机制进行网络优化;其中,双注意力机制针对输入数据是“属性词|属性”对这种“键向量|值向量”对的形式,在第一解码器的解码阶段采用双注意力机制分别对键向量和值向量均计算注意力数据,最终解码阶段采用的注意力数据分布是键向量和值向量各自注意力数据融合的结果;由于该方式可以同时利用键向量和值向量两部分的特征,能够提升第一文案生成模型规划的能力,提升文案的可靠性。如果将属性词注意力数据标记为α ij(1),属性注意力数据标记为α ij(2),则将属性词注意力数据和属性注意力数据融合后的注意力数据α ij如公式(6)所示:
Figure PCTCN2021127421-appb-000004
其中,J编码序列的长度,i是解码序列当前时刻的索引,j是编码序列当前时刻的索引。
在当前时刻编码端的注意力上下文向量c i如公式(7)所示:
Figure PCTCN2021127421-appb-000005
由于文案生成模型的一个问题是容易生成重复性描述,包括字面上的重复和语意上的重复,出现这种问题的原因是模型对某一个输入特征数据进行重复描述。而使用覆盖机制能够抑制重复描述生成,核心思想为:在文案生成过程中跟踪已经描述的属性词,让第一文案生成模型不再关注已经描述过的属性词;进而,降低商品文案的重复性,提升文案的质量。
具体做法是,首先维护在历史状态下注意力上下文向量c i,将其作为特征输入计算当前时刻的属性词注意力数据α ij(1)和属性注意力数据α ij(2),如公式(8)所示:
Figure PCTCN2021127421-appb-000006
其中,j’是编码序列不同时刻的索引,α ij(2)的计算公式同α ij(1),e ij是衡量解码端当前时刻第二关键属性数据的隐状态h i和编码端j时刻的隐变量h j的关系所计算的权重。
对于重复出现过高权重的词,在loss函数中给予适当惩罚,如公式(9)所示:
covloss j=∑ imin(α ij,c ij)     (9)
其中,c ij是将不同时刻编码端的注意力上下文向量累加后的结果。
步骤102:根据第一关键属性数据,得到商品的第一候选文案集;第一候选文案集表示至少一个商品文案的集合。
本公开实施例中,在得到第一关键属性数据后,第一文案生成模型可以根据第一关键属性数据,生成针对第一关键属性数据的文案描述;这里,每个关键属性数据对应生成的文案描述可以是一个,也可以多个。
在一种实施方式中,对于第一关键属性数据“圆领|领型”,第一文案生成模型对应生成的文案描述可以为“衣领为圆领设计”;也可以为“连衣裙的衣领为典雅的圆领设计”等。
在一些实施例中,根据第一关键属性数据,得到商品的第一候选文案集,可以包括:根据第一关键属性数据,逐句生成针对第一关键属性数据的文案描述;每个第一关键属性数据对应至少一句文案描述;将每个第一关键属性数据对应的文案描述进行拼接,生成至少一个商品文案;基于至少一个商品文案,得到商品的第一候选文案集。
在一种实施方式中,由于每个关键属性数据均可以生成对应的文案描述;因而,在第一关键属性数据包括多个属性数据的情况下,第一关键属性数据对应可以生成多种不同的文案描述。将多种不同的文案描述进行拼接,可以得到多种商品文案,进而,得到商品的第一候选文案集。
在一种实施方式中,假设第一关键属性数据包括:属性M和属性N;根据属性M可以生成文案描述1和文案描述2;根据属性N生成文案描述3;将描述1和文案描述3进行拼接、文案描述2和文案描述3进行拼接,则最终可以得到两种文案,将这两种文案作为第一候选文案集。
在一些实施例中,基于至少一个商品文案,得到商品的第一候选文案集,可以包括: 对每个商品文案的重复度和/或一致性进行判断,得到判断结果;重复度表示每个商品文案中不同文案描述之间的重复程度;一致性表示每个商品文案的属性数据与第一属性数据之间的一致程度;根据判断结果,得到商品的第一候选文案集。
本公开实施例中,在对不同关键属性数据的文案描述进行拼接后,还可以对拼接后的各个商品文案的重复度和/或一致性进行判断;该过程主要在第一文案生成模型的束搜索阶段进行实现。
其中,重复度判断是对每个商品文案采用字面重复判断以及词向量的语意级别判断,即指有连续重复的字、词、子句以及语意上重复的子句。一致性判断是针对属性词做判断,判断每个商品文案的属性词与第一属性数据每个属性词之间的一致程度;即,生成的文案中是否包含输入数据中不存在的属性词;其中,属性词可以通过属性词表与生成的文案进行匹配获取,属性词表可以通过语料库统计得到。
在通过第一文案生成模型对商品文案进行预测的束搜索阶段,可以采用硬规则方式,对每个商品文案中不同文案描述之间的重复程度进行判断,得到判断结果,如果判断结果中表明生成的文案描述之间存在重复的字、词、子句或语意上重复的子句,则将该商品文案进行删除;也就是说,只有判断结果表明生成的商品文案中任意不同文案描述之间均不存在上述重复情况,才可将该商品文案进行输出。
进一步地,对每个商品文案的属性词与第一属性数据每个属性词之间的一致程度进行判断,得到判断结果;如果判断结果表明生成的商品文案中包含输入数据中不存在的属性词,则将该商品文案进行删除;也就是说,只有判断结果表明生成的商品文案中包含的属性词均与输入数据中的属性词对应,才可将该商品文案进行输出。
图2为本公开实施例中通过第一文案生成模型进行文案输出的结果示意图,如图2所示,商品属性是第一文案生成模型的输入数据,解码输出得到的商品文案是没有增加重复度和一致性判断的生成结果;可以看出,该生成结果中“高腰”与第一文案生成模型的输入数据不一致,并且“穿着更加的舒适”和“让你的穿着更加的舒适”之间重复。在增加了重复度和一致性判别后,将“高腰”替换成“中腰”,“让你的穿着更加的舒适”替换成“让你的时尚感倍增”;可见,通过增加重复度和一致性判别,能够对第一文案生成模型生成结果中的错误描述进行纠正,提高商品文案的质量。
步骤103:按照质量判定规则对候选文案数据进行筛选,确定目标商品文案;候选文案数据包括第一候选文案集中的商品文案。
本公开实施例中,在得到第一候选文案集后,基于质量判定规则对第一候选文案集 中的商品文案进行筛选,确定最终输出的目标商品文案。
这里,质量判定规则包括以下至少之一:基于重复度对商品文案的质量进行筛选;重复度表示每个商品文案中不同文案描述之间的重复程度;基于一致性对商品文案的质量进行筛选;一致性表示每个商品文案的属性数据与第一属性数据之间的一致程度;基于困惑度对商品文案的质量进行筛选;困惑度表示每个商品文案中文案描述的清晰程度;基于属性覆盖度对商品文案的质量进行筛选;属性覆盖度表示第一属性数据在每个商品文案中的覆盖程度。
在一种实施方式中,可以基于重复度对第一候选文案集中的商品文案进行过滤;重复度包括字面上的重复和语意上的重复,其中,字面上的重复可以通过制定规则,判断每个商品文案中不同文案描述之间是否重复,例如相邻字词的重复,子句重复,属性词重复描述等。语意上的重复,通过训练word2vec词向量的方式,若发现相似词或相似子句,则判断商品文案之间存在重复问题。
在一种实施方式中,可以基于一致性对第一候选文案集中的商品文案进行过滤;由于保证输入数据和输出数据的一致性是对第一文案生成模型的基本要求,除了对模型优化生成一致的描述以外,为保证模型最终输出文案的属性数据与输入数据,即第一属性数据的一致程度,结合文案数据的特点,采用匹配属性词的方法判断最终输出文案的一致性,需要构建属性词表。基于属性词表,检测文案中描述属性词是否与输入数据的属性词存在冲突。其中,属性词表的构建,基于训练数据构建属性词表,构建中考虑属性词在文案中出现的频次和输入属性中出现频次的比例,同时考虑保留客观属性,例如材质属性,删除比较主观的属性,例如样式属性等。
在一种实施方式中,可以基于困惑度对第一候选文案集中的商品文案进行排序;第一文案模型生成的描述可能存在不通顺的情况,为了衡量生成文案的通顺度,采用语言模型中的困惑度指标度量文案,对文案进行排序,困惑度越高的文案一般情况下通顺性更差。基于已有的商品文案数据作为基础数据,统计二元模型下的概率,基于统计结果计算困惑度指标。基于困惑度指标计算当前商品所有候选文案的困惑度,并以此作为度量指标按照困惑度从低到高的顺序排序候选文案,取结果中候选文案排列在前的若干候选文案作为当前商品的新文案候选集。
在一种实施方式中,可以基于属性覆盖度对第一候选文案集中的商品文案进行排序;通过从多信息源如标题、扩展属性等获取的商品属性数据,经过过滤处理后,保留的属性数据作为文案生成模型的输入。生成的商品文案目标是对输入的属性做具体的描述, 吸引用户的购买兴趣。可以根据生成文案中包含的输入属性词的个数,判断商品文案的质量,描述的输入属性词越多,该商品文案的评分越高,文案质量越好。
在一些实施例中,按照质量判定规则对候选文案数据进行筛选,可以包括:在获取商品的第一属性数据后,将第一属性数据输入到至少两种文案生成模型中,得到商品的第二候选文案集;至少两种文案生成模型包括第一文案生成模型;按照质量判定规则对候选文案数据进行筛选;候选文案数据包括第二候选文案集中的商品文案。
在文案生成的过程中,除了采用训练完成的第一文案生成模型外,还可以采用其他文案生成模型;即,本公开实施例能够兼容各种文案生成模型。
对于商品文案生成任务,不再单纯依赖某个端到端的文案生成模型,而是基于多种文案生成模型共同生成商品对应的文案,得到商品的第二候选文案集;再基于上述的质量判定规则对第二候选文案集的商品文案进行筛选,将符合要求的商品文案进行输出;可见,采用这种方式进行商品文案生成,其准确率和召回率可以满足工业界的实际需要。
可以看出,通过上述重复度、一致性、困惑度和属性覆盖度四个方面的质量判定规则对候选文案数据进行筛选,不仅可以过滤掉有问题的商品文案,还能保留高置信度和高覆盖度的文案作为最后的输出,确保商品文案的质量。
本公开实施例提出了一种文案生成方法、装置、电子设备、计算机存储介质和计算机程序产品,该方法包括:该方法包括:获取商品的第一属性数据;基于预先训练的第一文案生成模型,确定商品的第一关键属性数据;第一关键属性数据表示第一属性数据中的部分属性数据;根据第一关键属性数据,得到商品的第一候选文案集;第一候选文案集表示至少一个商品文案的集合;按照质量判定规则对候选文案数据进行筛选,确定目标商品文案;候选文案数据包括第一候选文案集中的商品文案。如此,无需通过人工撰写商品文案,而是基于商品属性信息和预先训练的第一文案生成模型生成商品文案,能够提高文案生成效率;进一步地,按照质量判定规则对已生成的商品文案进行筛选,可以确保商品文案的质量以及与商品之间的契合度。
