![napkin text analysis - logo](./logo/logo.png)

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.

# requirements

- Python >= 3.6
- spacy.io
- redis (a redis server running on port 6380 is required)
- pycld3
- tabulate

usage: napkin.py [-h] [-v V] [-f F] [-t T] [-s] [-o O] [-l L] [--verbatim]
                 [--no-flushdb] [--binary] [--analysis ANALYSIS]

                 [--token-span TOKEN_SPAN]

Extract statistical analysis of text

optional arguments:
  -h, --help            show this help message and exit
  -v V                  verbose output
  -f F                  file to analyse
  -t T                  maximum value for the top list (default is 100) -1 is
                        no limit
  -s                    display the overall statistics (default is False)
  -o O                  output format (default is csv), json, readable
  -l L                  language used for the analysis (default is en)
  --verbatim            Don't use the lemmatized form, use verbatim. (default
                        is the lematized form)
  --no-flushdb          Don't flush the redisdb, useful when you want to
                        process multiple files and aggregate the results. (by
                        default the redis database is flushed at each run)
  --binary              set output in binary instead of UTF-8 (default)
  --analysis ANALYSIS   Limit output to a specific analysis (verb, noun,
                        hashtag, mention, digit, url, oov, labels, punct).
                        (Default is all analysis are displayed)
  --disable-parser      disable parser component in Spacy
  --disable-tagger      disable tagger component in Spacy
  --token-span TOKEN_SPAN
                        Find the sentences where a specific token is located

# example usage of napkin

## Generate all analysis for a given text

A sample file "The Prince, by Nicoló Machiavelli" is included to test napkin.

`python3 ./bin/napkin.py -o readable -f samples/the-prince.txt -t 4`

Example output:

# 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.
