Announces Winners of Sentiment & Opinion Mining Hackathon

15 July 2021

The three winning projects and category winners demonstrated the ease with which customer support can be enhanced with advanced natural language- (NL) based analytics announced today the winners of the “Sentiment & Opinion Mining Natural Language API” Hackathon. From May 6 to June 22, hundreds of developers across the globe unleashed their creativity to develop or enhance existing apps by using the NL API to identify emotions and traits within documents, chat messages and emails as well as ascertain the overall sentiment of the text.

Given that more than 80% of business data is unstructured and expressed in the form of language, accelerating time-to-value of more intelligent NL-aware apps is a business imperative. The NL API offers a simple and powerful way to address even the most complex unstructured data management use cases, including the ability to monitor reactions on social media, improve routing of customer support by capturing emotions and behavioral traits as well as to extract the general sentiment towards brands, events, policies, products, etc.

Fifty-seven projects were submitted to the Hackathon for a chance to win a total of $10,000 in prizes, and each project was judged on their creativity, the number of API features included in the project and the overall impact or potential value the project could provide to users. First, second and third prize were awarded to apps designed to augment user experiences by leveraging the natural language capabilities of the NL API to extract a deeper understanding of text.

  • First place went to Smart Voicenotes™ by EveryWord, an app that provides text versions of WhatsApp voice notes and a detailed summary of the key aspects, including sentiment analysis, key-phrase detection and named entity recognition features from, without ever leaving the WhatsApp user interface.
  • Second place was awarded to Clyde Chrome Extension, a Chrome extension that brings advanced natural language processing and opinion mining capabilities directly to a user’s browser.
  • Third place went to Multilingual Sentiment Analyzer which leverages the NL API functionalities together with tooling for information retrieval and machine translation, to make sure user feedback collections are easily searchable, and can be filtered at a fine-grained level before they are processed by the sentiment module.

The Hackathon also offered three category prizes to recognize the best project identifying sentiment of brands, companies or products, the best project identifying sentiment of events, policies or products, and the best project using customer interaction analytics to solve customer support challenges.
