From Data to Knowledge – Digital literacy at the service of corpora
| By Paulo Martins. University of Mihno, Braga, 11/11/2021 |
Learning a programming language
Coding literacy
Learning a programming language is easier than learning a natural language (?), explore new scientific strategies, automate daily tasks, boost problem solving skills.
NLP and data science
Data: raw, unstructured vs information: structured, organized…useful.
Some tools
Webcrawlers: fetching comments is challenging (javascript and stuff)
Json files Json syntax
YAGO is a knowledge base, i.e., a database with knowledge about the real world. YAGO contains both entities (such as movies, people, cities, countries, etc.) and relations between these entities (who played in which movie, which city is located in which country, etc.). All in all, YAGO contains more than 50 million entities and 2 billion facts.
YAGO arranges its entities into classes: Elvis Presley belongs to the class of people, Paris belongs to the class of cities, and so on. These classes are arranged in a taxonomy: The class of cities is a subclass of the class of populated places, this class is a subclass of geographical locations, etc.
YAGO also defines which relations can hold between which entities: birthPlace, e.g., is a relation that can hold between a person and a place. The definition of these relations, together with the taxonomy is called the ontology.

Recent DDL research & events: 5 tips
Really exciting times for DDL and corpus linguistics and education researchers. There’s some interesting new stuff that has just been published, including some interesting conference videos. Here’s my selection.

Abstract
The tools and techniques of corpus linguistics have many uses in language pedagogy, most directly with language teachers and learners searching and using corpora themselves. This is often associated with work by Tim Johns who used the term Data-Driven Learning (DDL) back in 1990. This paper examines the growing body of empirical research in DDL over three decades (1989-2019), with rigorous trawls
uncovering 489 separate publications, including 117 in internationally ranked journals, all divided into five time periods. Following a brief overview of previous syntheses, the study introduces our collection, outlining the coding procedures and conversion into a corpus of over 2.5 million words. The main part of the analysis focuses on the concluding sections of the papers to see what recommendations and future avenues of research are proposed in each time period. We use manual coding and semi-automated corpus keyword analysis to explore whether those points are in fact addressed in later publications as an indication of the evolution of the field
