NLP Engine Service
Overview
In the existing version of the chatbot, for PGR complaint creation feature, the user has to select his/her city from a drop-down menu by visiting the mseva website. This significantly reduces user convenience as the user is required to constantly switch pages. To overcome the above inconvenience, nlp-engine service is used. The service has an algorithm that uses fuzzy matching and pattern recognition to recognise the city provided by the user as input. Based on the user input, the cities having the highest match ratio with the input are being returned as the output list. A list comprising all the city names in English, Punjabi and Hindi was used as a reference tool for this service.
