# napkin-text-analysis
|
|
|
|
|
|
|
|
Napkin is a Python tool to produce statistical analysis of a text.
|
|
|
|
Analysis features are :
|
|
|
|
- Verbs frequency
|
|
- Nouns frequency
|
|
- Digit frequency
|
|
- Labels frequency such as (Person, organisation, product, location) as defined in spacy.io [named entities](https://spacy.io/api/annotation#named-entities)
|
|
- URL frequency
|
|
- Email frequency
|
|
- Mention frequency (everything prefixed with an @ symbol)
|
|
- Out-Of-Vocabulary (OOV) word frequency meaning any words outside English dictionary
|
|
|
|
Verbs and nouns are in their lemmatized form by default but the option `--verbatim` allows to keep the original inflection.
|
|
|
|
Intermediate results are stored in a Redis database to allow the analysis of multiple text files.
|
|
|
|

# what about the name?
|
|
|
|
The name 'napkin' came after a first sketch of the idea on a napkin. The goal was also to provide a simple text analysis tool which can be run on the corner of table in a kitchen.
