Improving Lost/Won Classification in CRM Systems Using Sentiment Analysis
Doru Rotovei, Viorel Negru · 2017
In this work, we are proposing several approaches to enhance lost/won classification of complex deals using sentiment analysis. The analysis of sentiments is done by text mining the activity notes recorded in CRM Systems used to manage complex sales. Using a baseline SVM model, we extended the baseline features with opinion predictors gathered using various techniques that included different preprocessing approaches of the CRM notes, scoring and counting of opinion sentences and inference of sentiment level features. We analyzed and compared the accuracy and f1-measure gained in comparison to the baseline and we discovered that, among the approaches analyzed, counting the polarity sentences gives the highest gain.
