Sentiment Analysis of the Consumer Review Text Based on BERT-BiLSTM in a Social Media Environment
Xueli Zhou
Dec 21, 2022
In this paper, a BERT-BiLSTM-based consumer review text sentiment analysis method in the e-commerce big data field is proposed. First, the unlabeled text is trained using the BERT training model for the language introduced in...
General tax structures and the Lévy insurance risk model
A E Kyprianou, X W Zhou
Jan 01, 0001
In the spirit of Albrecher and Hipp (2007), and Albrecher, Renaud, and Zhou (2008) we consider a Levy insurance risk model with tax payments of a more general structure than in the aforementioned papers, which was also...

The High-Quality Development of China's Publication Printing Industry From an Environmental Perspective
In this article, we measure the change in the green total factor productivity of the publication printing industry in 31 provinces in China between 2013 and 2019. An additive Luenberger-Hicks-Moorsteen total factor productivity...
Insights into azalomycin F assembly-line contribute to evolution-guided polyketide synthase engineering and identification of intermodular recognition.
Modular polyketide synthase (PKS) is an ingenious core machine that catalyzes abundant polyketides in nature. Exploring interactions among modules in PKS is very important for understanding the overall biosynthetic process and...

A Systematic Review on Engagement, Motivation, and Performance in MOOCs During the Post-Pandemic Time
Since the outbreak of the pandemic in 2019, pandemic prevention and control has gradually become normal, and internet-based massive open online courses (MOOCs) have become widely available. Aiming to give an insight into learner...
Budding-like division of all-aqueous emulsion droplets modulated by networks of protein nanofibrils.
Networks of natural protein nanofibrils, such as cytoskeletal filaments, control the shape and the division of cells, yet mimicking this functionality in a synthetic setting has proved challenging. Here, we demonstrate that...
