AI总结:

本文针对复杂支持工单解决效率低的问题,提出利用多源知识图谱嵌入增强学习排序算法,以更准确地推荐合适的工程师或工程师群组,实验表明其效果显著优于TF-IDF等传统方法。

摘要:

对超过160,000个客户案例的回顾表明,产品支持团队大约90%的时间都花在解决约10%的工单子集上,而这些工单往往不存在简单的解决方案。其中许多具有挑战性的案例需要多名工程师在一个“swarm(群组)”中协同工作,有些还需要作为缺陷提交给开发支持。这些具有挑战性的客户问题为机器学习和知识图谱提供了重要机会,可以识别出最能够解决问题的理想工程师或工程师群组(swarm),从而减少客户的等待时间。我们在此考虑的具体机器学习任务是一个learning-to-rank(LTR,学习排序)任务:给定一个事件以及当前分配给该事件的一组工程师(在非群组场景中该集合可能为空集),生成一个最适合帮助解决该事件的工程师排序列表。为了计算排序,我们可以考虑多种输入特征,包括客户提供的事件描述、受影响的组件、工程师对其专业能力的评分、工程师撰写的知识库文章文本、工程师撰写的客户回复文本,以及历史群组协作数据。核心假设检验是:通过纳入关于工程师解决过哪些案例的整体上下文数据,我们可以显著改进LTR算法,超越基准模型。本文提出了一种新颖的方法,对来自多个数据源(包括swarm信息)的知识图谱嵌入进行建模。所获得的结果证明,通过纳入这些额外上下文信息,我们可以显著改进推荐效果,超越TF-IDF等传统机器学习方法。

英文摘要:

A review of over 160,000 customer cases indicates that about 90% of time is spent by the product support for solving around 10% of subset of tickets where a trivial solution may not exist. Many of these challenging cases require the support of several engineers working together within a "swarm", and some also need to go to development support as bugs. These challenging customer issues represent a major opportunity for machine learning and knowledge graph that identifies the ideal engineer / group of engineers(swarm) that can best address the solution, reducing the wait times for the customer. The concrete ML task we consider here is a learning-to-rank(LTR) task that given an incident and a set of engineers currently assigned to the incident (which might be the empty set in the non-swarming context), produce a ranked list of engineers best fit to help resolve that incident. To calculate the rankings, we may consider a wide variety of input features including the incident description provided by the customer, the affected component(s), engineer ratings of their expertise, knowledge base article text written by engineers, response to customer text written by engineers, and historic swarming data. The central hypothesis test is that by including a holistic set of contextual data around which cases an engineer has solved, we can significantly improve the LTR algorithm over benchmark models. The article proposes a novel approach of modelling Knowledge Graph embeddings from multiple data sources, including the swarm information. The results obtained proves that by incorporating this additional context, we can improve the recommendations significantly over traditional machine learning methods like TF-IDF.
