The objective of this paper is to conduct bibliometric analysis of the relevant literature in the environmental field published from 1982 to 2018 collected by the Web of Science citation database and further explore the frontier research dynamics and hotspots in the environmental field. The word “oil spill*” was used as the subject term for retrieval. A knowledge map of hotspots in oil spill research was built through software VOSviewer and the clustering relations between them were explored. The frequency and relevance of the keywords in the corresponding literature were obtained by the matrix of keywords built through the Thomson Data Analyzer (TDA）software. The four main research hotspots of marine oil spill pollution were oil spill numerical simulation and model prediction, oil spill exposure toxicity and risk assessment, oil spill component and source analysis and oil spill pollution characteristics and treatment. The study analyzes the main content of the four research hotspots and the current research progress and provides scientific basis for further understanding of the mechanism of marine oil spill occurrence, migration and transformation, implementation of oil spill treatment and repair as well as more accurate assessment of eco-environment damage.

STEPS FOR GENERATING A VOSVIEWER NETWORK FILE FROM VANTAGEPOINT:
1. Generate an empty folder and copy a VantagePoint file of interest to it.
2. Copy Generate_VOS_Network_from_VP.vpm and Generate_VOS_Network_from_VP.xlsm to this same folder.
3. In VantagePoint run the script Generate_VOS_Network_from_VP.vpm.
4. You will prompted to select a field of interest. Select the same one selected to generate a VOS map file.
5. The script will prompt you for a network name. Give it one.
6. After it the script completes a (sparse format) VOS network file will be saved to the same folder housing the VantagePoint file you’re working with.
7. Simultaneously open the accompanying map file and network file you just generated in VOS (under the File tab).
8. The user has the option to adjust number of lines (we suggest 200) on the map, as well as their color, width and whether they’re curved or straight.
An online VOSviewer manual, which provides in-depth guidance on VOS maps, networks and manipulation the same, is available at:

One of the most difficult but yet unavoidable tasks for every academic field is to define its own nature and demarcate its area. This article addresses the question of how current computational text-mining approaches can be used as tools for clarifying what aesthetics is when such approaches are combined with philosophical analyses of the field. We suggest that conjoining the two points of view leads to a fuller picture than excluding one or the other, and that such a picture is useful for the self-understanding of the discipline. Our analysis suggests that text-mining tools can find sources, relations, and trends in a new way, but it also reveals that the databases that such tools use are presently seriously limited. However, computational approaches that are still in their infancy in aesthetics will most likely gradually affect our understanding about the ontological status of the discipline and its instantiations.

Run with a matrix open (like Matrix Viewer)
It will ask for a base filename to save.
It will create _map and _network_sparse text files.
Those files can be used in VOSviewer to Create a new map based on a Network.
Extended Abstract – NEW S,T&I VISUALIZATIONS session at “1st Global TechMining Conference” 2011
Author(s): Nees Jan van Eck and Ludo Waltman (Centre for Science and Technology Studies, Leiden University)
VOSviewer is a computer program that we have developed for constructing, visualizing, and exploring bibliometric maps of science (Van Eck & Waltman, 2010). The program is freely available on www.vosviewer.com. VOSviewer can be used for analyzing all kinds of bibliometric network data, for instance citation relations between publications or journals, collaboration relations between researchers, and cooccurrence relations between scientific terms. In this abstract, we focus on the use of VOSviewer for text mining purposes, in particular for analyzing large amounts of text data using so-called term maps.
