This technical note describes Lexbe’s Email Sentiment Analysis+ service which uses a Natural Language Processing (NLP) service to code email messages as positive, neutral or negative in overall sentiment. This is offered as part of Lexbe’s AI Insights service.
Lexbe’s Email Sentiment Analysis+ service can be run on email files within a Lexbe eDiscovery Platform (LEP) case and uses natural language processing to detect the overall sentiment/emotional tone of the document categorizing the value as either positive or negative.
The sentiment values are maintained per document in custom checkbox fields (Positive and Negative) within the LEP case. This allows for easy filtering and isolation. If no checkbox value is returned for a particular document, that concludes that the sentiment is neutral. This service can be particularly beneficial when working with emotionally charged disputes.
Lexbe’s Sentiment Analysis service can assist in:
Finding ‘smoking gun’ emails
Finding important emails when full review of all email is not practicable
Understanding dispute themes
Lexbe’s Email Sentiment Analysis+ service can be run on a case per request by Lexbe’s Professional Service team. Through automated processing, sentiment attributions (positive, neutral or negative) are recognized within the text and then extracted and maintained in custom document fields available for searching and filtering.
Once the Service is run, then the extracted and fielded data can be seen from the Doc Tab in the LEP Document Viewer for each document, or in a table from the Browse or Search pages with the specified columns (fields) showing.
