Data Preparation > Database > ISI > Co-Author Network
Extracts the co-authorship network from an ISI database.
Each author from each document in the input database is represented by a node. An edge is drawn between the nodes for two authors if and only if they co-authored a document in the input database.
The output network will include the following summaries of your dataset:
- Node (Author)
- Number of documents authored in your dataset.
- Total number of times cited. Note that this according to per-document citations in the global dataset as recorded by ISI and not according to citations contained only within your dataset.
- Publication year of the earliest document.
- Publication year of the most recent document.
- Edge (Co-Authorship)
Load an ISI file into the tool, then create a database from it using the ISI database loader.
For a quick analysis of a small dataset you may wish to merge together author entities with identical names. For a scientifically sound analysis of a larger dataset, you can find author entity merging suggestions (or manually set your own merging orders from scratch) and perform the merge.
The specific query run by the tool can be found in the source code.
