An Automated Text Classification Task is a Text-Item Classification Task that employs automated methods to assign text items to one or more predefined categories based on their content.
- Context:
- It can (typically) use machine learning algorithms and natural language processing techniques to analyze text data.
- It can (often) automate the categorization of text into document categories such as spam detection, sentiment analysis, and topic labeling.
- It can leverage both supervised learning and unsupervised learning approaches for model training and classification.
- It can utilize various feature extraction techniques such as bag-of-words, TF-IDF, and word embeddings to represent text items for classification.
- It can be applied across a range of applications, including email filtering, social media monitoring, customer feedback analysis, and document organization.
