AI总结:

本文提出将学习检索技术应用于 LinkedIn 职位搜索与推荐,分别利用录用数据构建资格图优化推广职位申请质量,并通过个性化嵌入与反馈规则提升自然职位参与度,同时开发了 GPU 端高效检索方案。

摘要:

网络规模的搜索系统通常采用“检索-排序”两步范式来应对可扩展性挑战。检索步骤(也称为候选选择)往往涉及提取标准化实体、构建倒排索引并执行词项匹配以完成检索。这类传统方法需要人工开发查询模型,耗时费力。本文讨论将学习检索技术应用于增强 LinkedIn 的职位搜索与推荐系统。在推广职位领域,关键目标是提升求职者质量,从而为招聘方客户创造价值。为此,我们利用已确认录用数据构建一个图,用于评估求职者对某一职位的胜任资格,并利用学习到的链接进行检索。我们学习到的模型易于解释、调试和调整。另一方面,自然职位领域的重点是优化求职者参与度。我们通过训练嵌入来实现个性化检索,并辅以一套源自会员反馈分类的规则加以强化。除了基于传统倒排索引的解决方案外,我们还开发了一种 GPU 端解决方案,能够高效支持 KNN 和词项匹配。

英文摘要:

Web-scale search systems typically tackle the scalability challenge with a two-step paradigm: retrieval and ranking. The retrieval step, also known as candidate selection, often involves extracting standardized entities, creating an inverted index, and performing term matching for retrieval. Such traditional methods require manual and time-consuming development of query models. In this paper, we discuss applying learning-to-retrieve technology to enhance LinkedIns job search and recommendation systems. In the realm of promoted jobs, the key objective is to improve the quality of applicants, thereby delivering value to recruiter customers. To achieve this, we leverage confirmed hire data to construct a graph that evaluates a seeker's qualification for a job, and utilize learned links for retrieval. Our learned model is easy to explain, debug, and adjust. On the other hand, the focus for organic jobs is to optimize seeker engagement. We accomplished this by training embeddings for personalized retrieval, fortified by a set of rules derived from the categorization of member feedback. In addition to a solution based on a conventional inverted index, we developed an on-GPU solution capable of supporting both KNN and term matching efficiently.
