Efficient dynamic pruning on largest scores first (LSF) retrieval

Kun JIANG,Yue-xiang YANG

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 1, Pages 1-14 doi: 10.1631/FITEE.1500190

Abstract: We propose another novel exhaustive index traversal scheme called largest scores first (LSF) retrieval, in which the candidates are first selected in the posting list of important query terms with the largestupper bound scores and then fully scored with the contribution of the remaining query terms.existing term-at-atime (TAAT) and the candidate selection cost of existing document-at-a-time (DAAT) retrieval, including two important optimizations called list omitting (LSF_LO) and partial scoring (LSF_PS) that

Improving retrieval precision of NO

Jinpeng YANG

Frontiers of Mechanical Engineering 2009, Volume 4, Issue 1, Pages 92-96 doi: 10.1007/s11465-009-0001-5

Abstract: The NO density error retrieved by the traditional method of differential optical absorption spectroscopy (DOAS) was analyzed. The technique for reducing the error is proposed and used to obtain the NO density of Chengdu through DOAS.

Verification of HY-2 satellite radar altimeter wind retrieval

Jia Yongjun,Zhang Youguang,Lin Mingsen

Strategic Study of CAE 2014, Volume 16, Issue 6, Pages 54-59

Abstract:

Sea surface wind speed has a very important role in the transfer of kinetic energy in the ocean, and the exchange of the matter and energy in the air-sea surface. The HY-2 satellite altimeter provides sea surface height, significant wave height, sea surface wind speed. And the accuracy of the wind speed affects the users’ application. In this study, the two-parameter algorithm is used to get the wind speed from HY-2 satellite radar altimeter. The correctness of this algorithm is calculated using the Jason-1 and HY-2 scatterometer data qualitatively. Three different methods(cross-over method, NDBC) are used respectively to evaluate this algorithm.

Paper evolution graph: multi-view structural retrieval for academic literature None

Dan-ping LIAO, Yun-tao QIAN

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 2, Pages 187-205 doi: 10.1631/FITEE.1700105

Abstract:

Academic literature retrieval concerns about the selection of papers that are most likely to matchMost of the retrieval systems are limited to list-output models, in which the retrieval results are isolatedIn this paper, we aim to uncover the relationships between the retrieval results and propose a methodto build structural retrieval results for academic literature, which we call a paper evolution graphFirst, the papers are soft-clustered into communities via metagraph factorization, during which the topic
