Downloading and indexing a fresh version of language models tagged for update on the Shiny app configuration tab
Tasks object for reporting progress and error messages, default: get_tasks()
Run a one shot task to download and index a local fasttext pretrained models. A fasttext model is a collection of vectors for a language automatically produced scrolling a big corpus of text that can be used to capture the semantic of a word.
The URL to download the vectors from are set on the configuration tab of the Shiny app.
This task will also update SVM models to predict whether a word is a location that will be used in the geolocation process.
The indexing is developed in SPARK and Lucene.
A prerequisite to this function is that the
