Data Preparation > Database > ISI > Extract Author Citation Network
Extracts the author citation 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 one of the Authors authored a Document that cited a Document that the other Author authored.
The output network will include the following data and metadata:
- Node (Author)
- All data from the PERSON table.
- A generated prettified label for identifying this Author.
- Number of documents authored in your dataset.
- Directed Edge (Citation)
- The number of times the target node Author cited the source node Author.
- Publication year of the earliest citing document.
Load an ISI file into the tool, then create a database from it using the ISI database loader.
It is strongly recommended that the database be cleaned before extracting any citation networks from it.
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.
Then, you will probably want to merge together Source entities according to recognized variants.
Finally, you must match References up to Documents in your dataset (there are no citations to analyze, otherwise).
The specific query run by the tool can be found in the source code.
