NLP Heatmaps

NLP Heatmaps expedite the process of uncovering insights from transcripts by making it easy to quickly analyze sentiment by category and subcategory across a set of peers or for an individual company over time.

Getting Started

You can access NLP Heatmaps from the upper right-hand corner of the Smart Summary pane, next to the Table View icon, or from the company profile in Document Search.

Time Series

NLP Heatmaps defaults to the Time Series view. 

Column headers refer to the calendar quarter-end date to allow easy comparison of events that took place around the same time.

The heatmap ranges from dark red (most negative, scores between 0 and 25) to dark green (most positive, scores between 75 and 100).  Neutral sentiment (scores between 46 and 55) is yellow, while categories with no data are gray.

Sentieo assigns sentiment at the sentence level.

Document sentiment is computed from sentence level sentiment with custom weights based on categories and frequency of positive and negative sentences.  Document sentiment scores range from 0 (most negative) to 100 (most positive).
