Global User-Level Perception of COVID-19 Contact Tracing Applications: Data-Driven Approach Using Natural Language Processing

Global User-Level Perception of COVID-19 Contact Tracing Applications: Data-Driven Approach Using Natural Language Processing

After manually analyzing and annotating users’ reviews, we employed both classical (ie, multinomial Naïve Bayes [MNB], support vector machine [SVM], random forest [RF]) and deep learning (ie, neural networks [11], fast Text [12], and different transformers [13]) methods for classification experiments. This resulted in 8 different classification models.

A Word Pair Dataset for Semantic Similarity and Relatedness in Korean Medical Vocabulary: Reference Development and Validation

A Word Pair Dataset for Semantic Similarity and Relatedness in Korean Medical Vocabulary: Reference Development and Validation

We applied 2 unsupervised word embedding models (Word2 Vec [11] and Fast Text [12]) to the Korean medical word pair sets, and the results were compared with those of the human evaluation. A Korean medicine–focused corpus with 129 million words (aforementioned) was used for model training. The preprocessing of the obtained corpus was twofold. First, the entire corpus data were segmented using the Korean Sentence Splitter (KSS) 2.2.0.2.

Preliminary Flu Outbreak Prediction Using Twitter Posts Classification and Linear Regression With Historical Centers for Disease Control and Prevention Reports: Prediction Framework Study

Preliminary Flu Outbreak Prediction Using Twitter Posts Classification and Linear Regression With Historical Centers for Disease Control and Prevention Reports: Prediction Framework Study

In this study, we demonstrate that using Fast Text (FT) can enhance the efficiency of Twitter-based flu outbreak prediction models. Originally, FT became an efficient text classifier that was proposed by Facebook. FT performs more quickly than deep learning classifiers for training and testing procedures and produces comparably accurate results. The FT classifier can train more than a billion words in about 10 min and then predict multiple classes within half a million sentences in less than a minute [16].
