# Question Answering
|
|
|
|
- [Project repository](https://git.kemt.fei.tuke.sk/dano/annotation) (private)
|
|
- [Annotation Manual](navod)
|
|
- [Summary database application](https://app.question.tukekemt,xyz)
|
|
|
|
|
|
## Project Description
|
|
|
|
- Create a clone of [SQuaD 2.0](https://rajpurkar.github.io/SQuAD-explorer/) in the Slovak language
|
|
- Setup annotation infrastructure with [Prodigy](https://prodi.gy/)
|
|
- Perform and evaluate annotations of [Wikipedia data](https://dumps.wikimedia.org/backup-index.html).
|
|
|
|
Auxiliary tasks:
|
|
|
|
- Consider using machine translation
|
|
- Train and evaluate Question Answering model
|
|
|
|
