Opinion mining extracts opinions expressed by a specified target from a set of documents. Opinion mining determines sentiment orientation positive, negative, or neutral of a (short) text and is a text understanding technology assisting people locate relevant opinions in a review collection of large ...
(SVM), and Artificial Neural Networks (ANN). There are also classification methods based on Decision Trees (DT), k-Nearest Neighbor (k-NN), k-means, and Naive Bayes Classifiers. In addition to usage of single classifiers, ensemble methods are also used for SER that combines several ...
This study examines the effectiveness of state-of-the-art supervised machine learning methods in conjunction with different feature types for the task of automatic annotation of fragments of clinical text based on codebooks with a large number of categories. We used a collection of motivational inter...

More specifically, they investigate the ability of BERT for capturing hateful context within social media content by using new fine-tuning methods based on transfer learning. BERTBASE with an Inserted CNN layer proved to be the best model, leading to F1 of 0.88 on the W&H and of 0.92 on ...
Using threshold values, they have shown threshold effects at various risk levels and validated the use of these thresholds on a public domain, proprietary dataset, KC1 obtained from NASA and two open source, promise datasets, IVY and JEdit using various machine learning methods and data mining ...
