A term project by Sen Sub Laban (sen.s@pitt.edu).
Completed Feb. 10, 2023 through Apr. 30, 2023.
This project investigates the morpheme acquisition order of native English speakers and English language learners. Based on 'natural order studies,' which are influential in the fields of linguistics and second langauge acquisition, the project takes a data-science approach to analyzing the developmental patterns of grammatical morphemes in language acquisition.
The data sources utilized in this project are sourced from TalkBank. I focused on two corpora:
-
CHILDES Frogs English Slobin Corpus (Native speakers)
-
Vercellotti Corpus (Language learners)
-
Final report provides a complete overview of this project and its outcomes.
-
notebooks contains the Jupyter Notebook files:
-
data_samples contains stored csv files of the data frames utilized throughout the project.
- visuals is the folder containing all visualizations generated throughout this project.
-
Final_Presentation.pdf is a copy of the presentation aid utilized for a presentation about this project on Apr. 14, 2023.
-
Progress report details progress made on this project throughout the semester.
-
Project plan was the original plan developed at the start of this project.
