In the heart of Paris, a leading restaurant that has been operating for decades faced a challenge. The reviews by customers were hand-written about their experience at the eatery. Thus, there was a need to make those reviews be seen widely to the large number of people in the current digital age. Also, there was a need to understand the sentiments of the customers clearly.
Armed with cutting-edge Natural Language Processing (NLP) technology, GrowExx started on a transforming journey to understand sentiment in different languages and to present a total analysis of sentiment.
Natural language processing (NLP) is a type of artificial intelligence in which computers can understand, produce, and manipulate human language. NLP drives a wide variety of applications, like language translation, sentiment analysis, and chatbots, and leads to massive changes in the way humans communicate with computers.

Client Background

The client is a famous restaurant that has been in the heart of Paris for several years, and they had a lot of handwritten reviews from customers. Transforming the traditional legacy into the modern digital transformation was regarded as a challenge as well as an opportunity.

Challenges Faced

The restaurant encountered two primary challenges:
  • One issue that the restaurant was facing was with the handwritten reviews because in today’s digital world hand-written reviews don’t work much because they are not scalable at all. While digital texts are easy to read, handwritten text requires laborious transcribing, and are also error prone. Moreover, the issue with the handwritten reviews is that it becomes sometime tough to keep the track of the handwritten reviews, but when it comes to digital records; they are much easy to manage. This poses a very serious challenge when it comes to identifying and extracting meaningful information for routine purposes such as sentiment analysis.
  • The restaurant had customers from various backgrounds and the reviews were written in all different languages. Thus, there is a need for a solution that could understand the reviews and sentiments of the people in whichever language they are.

  • Preservation of Culinary Heritage Years of manual written reviews were replaced with the electronic form of recording, safeguarding the vivid culinary history of the restaurant.
  • Quantifiable Impact: Through a comprehensive analysis of diverse metrics, it was found that the restaurant’s online presence has risen by 40% which is quite a significant improvement. These included following website traffic trends with the help of tools such as Google Analytics, and watching how people engage on social media across various platforms.
