4. Legal AI for Indian Context
District courts are usually the first
point of contact between the people
and the judiciary.
Lower courts in India are burdened
with a backlog of cases (~40 million
as of 2021).
Local languages used in the
documents filed in district courts in
India.

5. Legal AI / NLP - Data
We collected ~900k district court case documents from Uttar
Pradesh
All documents in Hindi, written in Devanagari
There are legal corpora for European Court of Justice and Chinese
courts, none for Indian district courts

6. Legal AI / NLP - Data
There are around 300 different case types, table shows the prominent
ones
Majority of the case documents correspond to Bail Applications

Variation in number of case documents per district
Case types in HLDC

7. Legal AI / NLP - Bail Documents
7
District-wise ratio of number of bail applications to total cases

8. Legal AI / NLP - Bail Prediction Model
8
In general, the performance is lower in district-wise settings, possibly due to large
variation across districts
Overall, summarization models perform better than Doc2Vec and simpler
Transformer-based models

HLDC: Hindi Legal Documents Corpus

10. Legal AI / NLP for Indian Context - Takeaways
Indian Legal documents are a rich a source of domain-specific Indic-
language corpora, readily available online.
Multiple tasks still need attention especially for Indian settings

28. Code-mix computationally challenging hai.
Predominantly noticed in social networks and speech data
Social Media text processing poses certain challenges
@, #, https://

29. Task Oriented Dialog System in Hindi and
Code-Mix English-Hindi
29
Paper at ACL Findings 2023
Task Oriented Dialog Systems are specific to tasks – e.g
hotel reservation
We develop datasets for Hindi and Code-Mixed English-
Hindi.
Dataset provides a good benchmark to test multilingual
chatbots, specifically code-mix chatbot.

30. A pipeline to generate code-mix sentences

31. Problems / Applications
Identify code mix sentences in wild
Generating natural code mix sentences
Downstream application in dialog systems, human computer interface
Making sense of the social content can help in making choices,
recommendations, civic services, etc.
