  In the proposed demo, we will present a new software - Linguistic Field Data
Management and Analysis System - LiFE (https://github.com/kmi-linguistics/life)
- an open-source, web-based linguistic data management and analysis application
that allows for systematic storage, management, sharing and usage of linguistic
data collected from the field. The application allows users to store lexical
items, sentences, paragraphs, audio-visual content with rich glossing /
annotation; generate interactive and print dictionaries; and also train and use
natural language processing tools and models for various purposes using this
data. Since its a web-based application, it also allows for seamless
collaboration among multiple persons and sharing the data, models, etc with
each other.
  The system uses the Python-based Flask framework and MongoDB in the backend
and HTML, CSS and Javascript at the frontend. The interface allows creation of
multiple projects that could be shared with the other users. At the backend,
the application stores the data in RDF format so as to allow its release as
Linked Data over the web using semantic web technologies - as of now it makes
use of the OntoLex-Lemon for storing the lexical data and Ligt for storing the
interlinear glossed text and then internally linking it to the other linked
lexicons and databases such as DBpedia and WordNet. Furthermore it provides
support for training the NLP systems using scikit-learn and HuggingFace
Transformers libraries as well as make use of any model trained using these
libraries - while the user interface itself provides limited options for tuning
the system, an externally-trained model could be easily incorporated within the
application; similarly the dataset itself could be easily exported into a
standard machine-readable format like JSON or CSV that could be consumed by
other programs and pipelines.
