摘要
本测评采用Pooling技术,旨在考察NSTL智能检索平台的扩展检索效果。实验表明,基于STKOS的概念扩展检索能够有效地提高检索召回率,与此同时也导致整体检索准确率下降。实验结果中,扩展检索在MAP和P@10两个指标上的表现均优于NSTL现有生产平台,表明该功能能够给用户带来更好的检索体验。
The objective of this retrieval evaluation winch uses Pooling technology is to investigate the effect of the expand retrieval of the NSTL intelligent retrieval platform. The results show that, the expand retrieval based on STKOS can effectively improve the recall, but also lead to the decrease of the precision. In the results, MAP and P@10 of the expand retrieval are better than those ofNSTL＇ s current platform. This shows that this function can boost users＇e xperience.
