Network Analysis

Network analysis examines and visualizes the relationships between publications based on authorship, citations, or common terms.

There are three types of bibliometric networks:

• Collaboration Networks show collaborations between authors, institutions, or groups (such as NOAA line offices). Collaboration network maps illustrate how various parties are working together.
• Semantic Networks or word co-occurence network maps show the most commonly co-occurring words in the titles, abstracts or keywords of articles in a given set. These networks are useful in showing how how potentially diverse areas of research interrelate and overlap.
• Citation Networks illustrate relationships between publications based on citations. There are three types of citation networks: direct (connecting articles that cite each other); co-citation (connecting articles cited by the same publications); and bibliographic coupling (connecting articles that are cited by the same publications). These networks can be useful in illustrating emerging research trends and "hidden" research communities.
