Natural Language Processing: Projects

The 2020 episode at Faculty of Mathematics, Physics and Informatics of Comenius University

This site lists various ideas that could be explored as possible projects as part of the NLP course. The list is far from exhaustive, but represents (current) course instructor('s/s) interest.

All of the ideas assume the final project will contain some "novelty bits", either in the explored idea itself, its execution, practical usability or the underlying dataset.

Creating a new dataset for any of the NLP tasks listed below (or any other, really) is a huge plus.

Language Modeling

Can we build a state-of-the-art language model for Slovak, using some of the new tricks (, which can then be used in all the other tasks?

Since we already have all these Camembert's, BERTje and what not, can we build some sort of other language variation of BERT?

Text Classification

Pick any interesting text dataset, the text of which can be classified into various categories and try a couple of methods.

  • Language identification
  • Sentiment analysis of Anketa comments
  • Detection of inappropriate comments in Anketa
  • Adaptation of Label-wise attention to other non-Twitter data (or to new Twitter data)
  • Applications of Active Learning in context of classification

Key Phrase Extraction

Given a body of text (say a document or a news article), can we extract the most important phrases out of it (and hence help summarize it a bit)?

Various approaches do exist (many of the popular ones are implemented as part of the pke module) -- could you think of a dataset where something like this could be useful? Could we perhaps build one automatically (with the expected keywords attached)?


Can we build a Slovak/Czech/Croatian/Serbian summarization dataset that would allow us to use the extractive approach to summarize (say) news articles?

Can we use the TextRank algorithm to perform extractive summarization, or generate a list of keywords for a given body of text? Can you think of some interesting text for which this method would be a good fit?

Portmanteau Generation

Given words A and B, can we create their portmanteau C?

A B Portmanteau
beef buffalo beefalo
sheep people sheeple
breakfast lunch brunch
frozen yogurt froyo
parachute trooper paratrooper
emotion icon emoticon

Or better yet, given the words A and B can we create a portmanteau C that would not directly feature A or B but would still be related? Such as for instance

A B Portmanteau
angry Mozart scaria (scary / aria)

Here is a quick demo of such approach, which requires a pretty complex setup and external tools, such as the CMU Pronouncing Dictionary, which makes it pretty difficult to port this approach for different languages.

Is there something we can do to work around that? Some neural approach perhaps?

Your own idea!

Feel free to come up with an idea on your own -- if you are working on something NLP-related for your thesis, that would be a good candidate. But in general, I'd be happy to talk about any NLP-related idea you may have.

Alternatively feel free to check out the sites below, find a NLP task you find interesting and see if you can make an interesting project out of it!
