Demo of LiFE: A web app for collection, management and annotation of linguistic data

User-friendly and full-fledged data management and analysis systems are always a valuable asset for field linguists and NLP practitioners. In our proposed demo, we will present a new software - LiFE - Linguistic Field Data Management and Analysis System. It is an open-source, web-based tool for managing and analysing linguistic data that makes it possible to systematically store, share, annotate and use (for different linguistic purposes) data collected from the field, or crawled from various sources like YouTube, Blogs, Facebook, Instagram, Newspaper, Twitter, Newspapers, Wikipedia, etc. It follows a user-friendly full-fledged two-way pipeline for multimodal data to fill the void among field linguists and NLP practitioners: (i) field linguists' pipeline to collect data from speakers in the field and analyze further to develop lexicons, educational resources, and potential language technologies; (ii) NLP practitioners' pipeline to crawl data from the web sources using automatic or semi-automatic crawlers or manually, annotate further to develop various language technologies. The source code of the app is made freely available for researchers under AGPL license and the app is currently online on our website. It is licensed for commercial use under distinct, specific terms and conditions. As of now, over 200 users are registered on our server and it is being hosted by three other organizations as well on their respective servers and is being used in their projects.
