Installation

pip install RGPageRank

Usage

from RGPageRank import PageRank

You may pass either directory name or dictionary with data as a first (data) parameter to the new object:

dir_pg = PageRank('directory_name', recursive=True, truncate_extension=True)

Where:

1. directory_name - can be either absolute path to a directory or relative path, in the second case the script will use path of the script where the script file contains
2. recursive - read nested directories or not
3. truncate_extension - truncate extensions of the files

Each file name inside the directory is a node name and content are the corresponding data:

dir:

1. test.txt
2. test1.txt
3. nested_dir:

1. test2.txt
2. test.txt

So it will be: {'test': 'test data', 'test1': 'test1 data', 'test2': 'test2 data'}

If there are files with the same name the content of the files will be merged, so the dict above will contain data from 'dir/test.txt' and 'dir/nested_dir/test.txt' for the 'test' key

dict_pg = PageRank({'Jimmy': 'Hello John and Carl, Carl', 'Carl': 'Hi John', 'John': 'Sup Jimmy and Carl'})

To get page rank for the data use either 'page_rank()' or 'sorted_page_rank()'

print(dict_pg.page_rank())

print(dict_pg.sorted_page_rank(reverse=True))

There are also two helper classes: DictTransformer and DirectoryTransformer which is actually transform a given data to a directed graph you may use it to get the graph and do something with it or draw the graph

from RGPageRank import DictTransformer

from RGPageRank import DirectoryTransformer

dir_transformer = DirectoryTransformer('directory_name', recursive=True, truncate_extension=True)

dict_transformer = DirectoryTransformer({'Jimmy': 'Hello John and Carl, Carl', 'Carl': 'Hi John', 'John': 'Sup Jimmy and Carl'})

print(dir_transformer.make_graph())

dir_transformer.draw_graph()

print(dict_transformer.make_graph())

dict_transformer.draw_graph()
