What is IBM Tool for Interactive Text Classification and Labeling?
Whether your application supports customer satisfaction analysis, root cause determination, or churn predication, your application needs to classify large body of text data into correct set of groups. An incorrect classification could potentially lead to wrong conclusions, mis-allocation of resources, and delay in resolution of problems.
Manual approaches to classification of data can be expensive, error prone, and unsuitable for a large amount of data. Automatic classification systems are also prone to error and poor quality. For example, classification can be affected by uncertain labeling semantics and ambiguity in text.
IBM® Tool for Interactive Text Classification and Labeling bridges this gap and provides a comprehensive interactive interface for
- correcting and refining automatic text classification models through human feedback
- continuously inspecting and validating pre-classified data in order to ensure consistency
- building "good" training data from scratch.
How does it work? This tool has three components:
- The Classifier is an automatic text classification module that must be trained using a few pre-labeled documents. A model is created as a result of this training process. After the model is created, it can be applied to predicting labels for new documents with a confidence score assigned to the classification process.
- Confidence-based selection allows users to select an active document set based on thresholds on confidence or randomly validate or alter predicted labels.
- Model improvement uses feedback to improve the classification model by re-training. It incorporates those documents that are most informative to the current model.
