Abstract
Based on the interaction data and response data, an interaction monitoring platform may determine a first known sentiment and a second known sentiment, identify a first pattern and a second pattern in the interaction data, and generate a first pattern-level sentiment and a second pattern-level sentiment based on the known sentiments and the identified patterns. A binary indicator may indicate which identified patterns are exhibited in a subset of the interaction data. The platform may train a gradient boosting model using known sentiment as a target variable and using binary indicators and pattern-level sentiments as input data. The platform may predict a sentiment corresponding to a subset of interaction data with unknown sentiment that exhibits one or more of the first pattern or the second pattern based on a binary indicator and the trained gradient boosting model.
