extract the weighted document-document network for an ISI database |

##### Menu Path

Extract -> From ISI Database -> Extract Weighted Document-Document Network

##### Input Parameters

...

###### Threshold

...

Any document-document edge whose calculated similarity is below this value will not be given an edge in the network output by this algorithm.

...

###### Comparison Algorithm

...

The comparison algorithm is used to calculate the similarity between documents. You may select between the following algorithms:

##### Output

A network file with all documents connected by a weighted edge as calculated by the *comparison algorithm* if the weight of the was above the *threshold* value.

##### Usage Hints

The Cosine Similarity *comparison algorithm* does not preform any real comparison between the terms. It only uses the existence or nonexistence of a term in the set for the calculation.

##### Implementation Details

The Cosine Similarity *comparison algorithm* does not preform any real comparison between the terms. It only uses the existence or nonexistence of a term in the set for the calculation.

The network file has the following node and edge properties:
