摘　　要：[目的／意义]数据科学作为一个融合诸多领域的新兴交叉学科正在快速形成。从数据科学招聘的公告信息中，抽取出相应的实体知识不仅有助于从市场的角度了解数据科学的发展动态，而且有助于改进数据科学教学的内容。[方法／过程]基于各大招聘网站职位招聘公告，结合情报学的数据获取、标注和组织方法，构建数据科学招聘语料库并从中抽取相应的实体进行分析与研究。[结果／结论]在搜集到的11000篇经过标注的职位招聘公告语料的基础上，基于Bi-LSTM-CRF、CRF和Bi—LSTM模型，对数据科学招聘实体的抽取任务进行性能的对比，确定最终的数据科学招聘实体自动抽取模型，设计数据科学招聘实体自动抽取平台，并构建数据科学招聘实体网络。[ Purpose/significance] Data science is emerging as a new interdisciplinary field which combines many fields. Extracting the corresponding entities knowledge from the announcement information of data science recruitment can not only help to understand the development of data science from a market perspective, but also help to improve the content of data science teaching. [ nethod/process] Based on the recruitment announcement from the recruitment website, combining with information science data collection, annotation and organization methods, data science corpus was constructed and the corresponding entities from it were extracted. [ Result/conclusion] In the existing 11000 annotated data science corpus scale recruitment announcement, based on the Bi-LSTM-CRF, CRF and Bi-LSTM models, this paper compared the extraction performance of data science recruiting entities and fnally determined the final data science recruitment entities automatic extraction model, designed the data science recruitment entities automatic extraction platform, and built a data science recruitment entities network.
