Continuous location privacy protection mechanism based on differential privacy

open access: yesTongxin xuebao, 2021
Aiming at the problem of users’ location privacy leakage caused by continuously using LBS, a road privacy level (RPL) algorithm was proposed based on road topological network, which divided the privacy level of the road sections around the sensitive ...

Assessing tree-related microhabitat retention according to a harvest gradient using tree-defect surveys as proxies in Eastern Canadian mixedwood forests

open access: yesThe Forestry Chronicle, 2019
Tree-related microhabitats (hereafter “TreMs”) play a key role in forest biodiversity. However, harvesting may cause their erosion. In North America, knowledge about TreMs is still lacking but defect surveys are largely available in managed forests.

Tree Framework With BERT Word Embedding for the Recognition of Chinese Implicit Discourse Relations

open access: yesIEEE Access, 2020
Currently, discourse relation recognition (DRR), which is not directly marked with connectives, is a challenging task. Traditional approaches for implicit DRR in Chinese have focused on exploring the concepts and features of words; however, these ...
