# label_bios

> Categorize people into fields of occupation using their bios (biographies). 

The categorization is performed using a predefined lookup-table matching certain keywords
with associated fields of occupation. E.g. bios will be categorized as "journalists" if their
texts contain any of the following words: "periodista", "journalist", "journalism", "periodismo",
"news", "noticia", "noticias".

Possible categories currently are:

* journalists
* business
* developers
* marketing
* travel
* photography
* university
* seo
* blogging
* sports
* politics
* social sciences
* medical
* entertainment
* art design
* economics
* videogames.
