As part of the Language Sciences, Language and Cognition and English Linguistics curricula of the Master's Degree in Language Sciences, and as part of the English and American Literary and Cultural Studies curricula of the Master's Degree in European, American and Postcolonial Languages and Literatures, this course aims at providing the student with an hands-on training on the basic techniques for the computational annotation and analysis of written text.

The main goals of this course are:

- to provide students with the basic technical tools for the computational treatment of textual data
- to introduce students to the fundamental automated knowledge extraction techniques
- to introduce the student to the Python programming language and to some of its modules, among which stanza and gensim
- to stimulate critical thinking and the ability to think out of the box
1. Knowledge and understanding
- familiarity with the Python programming language and with some of its NLP/text mining packages (stanza, gensim)
- familiarity with the most commonly used techniques of (morphosyntactic) linguistic annotation
- learning of the basic techniques for the extraction of linguistic knowledge from corpora
- knowledge of the principal levels of linguistic annotation
- familiarity with the most commonly used techniques for the representation of structured information extracted from text

2. Applying knowledge and understanding
- knowledge of the features and limitations of the most common computational linguistics tools and approaches, so as to be able to pick the most appropriate solution for a given linguistic research issue
- use of Python for the implementation of scripts for the quantitative and computational analysis of text
- ability to advance and test original and sounded hypotheses

3. Making judgements
- ability to implement self-development strategies to improve technical skills
- awareness of the technical and deontological issues connected to the automatic treatment of language
- ability to compare competing hypotheses

4. Communication skills
- ability to write a report to describe the process, progress and result of an original scientific research
- ability to interact with researchers with a different scientific background
- ability to interact with the other students and the professor

5. Learning skills
- ability to learn novel scripting languages (among which, R, PERL, Matlab, Javascript, SQL)
- ability to acquire technical knowledge pertaining to issues only indirectly linked to the automatic treatment of language (e.g. the statistical analysis, the creation of web pages, the management of a database)
- ability to learn novel technical tools for the automatic treatment of language (e.g. annotation tools, corpora management and query tools)
Basic notions of general linguistics (morphology and syntax)

Basic familiarity with computers, but no special experience with programming or software is expected
1. Intro to Python Programming
2. Python programming basics
3. Variable Types
4. Text manipulation in Python
5. Writing structured programs
6. The automatic annotation of a corpus
7. Descriptive statistics for corpus linguistics / the Zipf's law
8. Collocations and association measures
9. Mapping for digital humanities
10. Vector Semantics
11. Topic modeling
Even if the Jupyter notebooks available on the university e-learning platform are mostly self-contained, the following background readings will provide the student with an in-depth explanation of the key concepts of the course:

Learning assessment will be based on a series of programming exercises published on the university e-learning platform. Students are required to submit their solutions electronically by due date and to discuss them with the instructor on the day of the exam.
Lab sessions structured as follows:

- overview of the session key concepts and principles
- work on the programming exercises in the relevant Jupyter notebook available on the university e-learning platform
