Twitter alloy steel disambiguation and user relevance via one-class and two-class news titles classifiers

Abstract: This paper addresses the nontrivial task of Twitter financial disambiguation (TFD), which is relevant to filter financial domain tweets (e.g., alloy steel or coffee prices) when no unique identifiers (e.g., cashtags) are adopted. To automate TFD, we propose a transfer learning approach that uses freely labeled news titles to train diverse one-class and two-class classification methods. These include different text handling transforms, adaptations of statistical measures and modern machine learning methods, inc… Show more

“…e overall index of prediction accuracy of method 2 has decreased compared with method 1. e reasons for this are that, in addition to the input error, the description of the test subject's personality and mood state is not precise enough, leading to errors in making predictions; the errors will continue to accumulate in the course of continuous experiments, leading to a continuous decrease in the nal prediction accuracy. ese are the areas that need to be improved in the next step [25,26].…”

“…The audience of financial news is increasing. The audience of financial news is widely distributed in all corners of society, but it cannot be understood that every member of society is the audience of financial news [18,19]. Among them, the real financial news audience refers to the part that has long adhered to and paid attention to the financial information on the news media.…”

“…Also known as unary classification, OCC can be viewed as a subclass of unsupervised learning, where the Machine Learning (ML) model only learns using training examples from a single class [8,9]. This type of learning is valuable in diverse real-world scenarios where labeled data is non-existent, infeasible, or difficult (e.g., requiring a costly and slow manual class assignment), such as fraud detection [10], cybersecurity [11], predictive maintenance [12] or industrial quality assessment [13].…”
