Find terms that are prevalent and reveal a significant impact on a measurable aspect of your data in Daylight’s Drivers feature. For example, in a restaurant review project where “scores” are star ratings, the concept “long line” might be a negative driver. A driver’s impact represents the difference between the average score for all documents and the average score for documents that contain the concept you selected. If “long line” has an impact of -0.6 stars, reviews containing “long line” or its conceptual matches are an average of 0.6 stars lower.
