Make Pajek Network

This application takes a number of entities, for example keywords or companies, as the input and transforms it into a Pajek-network file. It can however be used for basically any type of network; words, literature, communication, inter-organizatinal... It simply produces a Pajek network file from the input data.

1

Input

The input should be formatted as follows: (see examples below)
Each row defines one set of related entities.
Each entity in the row is related to every other entity in the row. The entities on a row should be separated by a comma!
Consider making the text either UPPER or lower case.


Example of input:

business relationships, connectedness, business networks
business relationships, adaptation, commitment, trust
business networks, connectedness, embeddedness, structure

Functions

a)
Use filter Off On
Filter the following nodes/words (case insensitive):


b) Replace certain nodes being the same (or words with the same meaning) Off On
Case insensitivity of replace Off On
(replacement: original1; original2; etc)


c) Embedded weighting (each node ends with a space and a number, e.g. node +5, missing equals 0)
Off Use sign (+/-) Add absolut numbers Multiply

d) Look for timestamps or indicator of order.
Place a timestamp of any format on a row of its own, spaces can be replaced with "_" and ":" with "#". The line must start with [TIME] and can end with [comment] (optional), e.g. [TIME]2007-03-31_23#59[First quarter].
Each timestamp will be applied for all consecutive lines, until a new timestamp is found.
Off On
If timestamp is on, use entire timestamp or just a part of it? (e.g. for reducing 2007-05-30_10#41 to 2007-05)
Use entire Use part start: length:

e) Type of connection between nodes
Connect all nodes in each line Connect each node with the subsequent node(s)
