Formal concept analysis lattice generation and query in Java

FCA-Java

Formal concept analysis lattice generation and query in Java.

Dependencies

• JUNG for generating the lattice

Usage

For the following context

  |   1   |   2   |   3   |   4   |
--|-------|-------|-------|-------|--
a |   1   |   0   |   1   |   0   |
--|-------|-------|-------|-------|--
b |   1   |   1   |   0   |   1   |
--|-------|-------|-------|-------|--
c |   1   |   0   |   1   |   0   |
--|-------|-------|-------|-------|--
d |   0   |   1   |   0   |   1   |
--|-------|-------|-------|-------|--

First the program would ask for number of object and number of attributes. Then you need to input the objects separated by space::

a b c d

After that you need to provide the attributes separated by space:

1 2 3 4 5

and last input would be the matrix, in row major order:

1 0 1 0
1 1 0 1
1 0 1 0
0 1 0 1

A window will open containing the representation of the concept lattice. And you can query the concepts i.e. extent for a given intent or intent for a given extent in terminal.
