This is an explanation of how to use the interactive visualizations, as well as an overview of relevant terminology.
In order to zoom, use the buttons at the bottom of the page, or scroll down using your mouse. The zoom speed is quite quick, so this takes some getting used to. As you zoom in, more and more of the smaller labels will start appearing. Also, the visualization will become less crowded, which is particularly useful for visualization II.
In order to navigate the visualization, you need to press down and then drag your mouse around.
When you hover over a particular word, all other words and connections will fade out. What remains at full opacity is the disciplinary connections of that word.
If you click on the word, all other connections and words will disappear, and you will be given a smaller network that shows the disciplines in which the word occurs. In order to return to the full visualization, click the link at the top right of the page.
The information pane at the right of the page presents various statistics related to the word you clicked.
Betweenness Centrality- for most visualizations, this statistic was not computed, and can therefore be disregarded
Modularity Class– identifies the primary discipline in which the word appears
Eccentricity– the number of “steps” between the selected word and the furthest word connected to it. For example, an eccentricity of 1 indicates that, at most, one word/discipline separates the selected word from its furthest connection. In most cases, the eccentricity is either 0 or 1.
Closeness centrality– indicates, as the name suggests, the centrality of the selected word in relation to the entire visualization. The higher this number, the less central the word.
Connections– all words/disciplines associated with this word. They link to their respective sub-visualizations.
On the right hand panel can be found a brief description of the visualization, the legend, as well as two search options. One can search for a particular word, or by discipline (group selector).
Tips for particular visualizations:
EH Topic Modeling II- click on disciplines themselves to see what words they are associated with.
EH Topic Modeling III: the words in light green are words that occur in more than one discipline an equal number of times.
EH Topic Modeling IV: the words in grey are words that occur in more than one discipline an equal number of times.
Topic Modeling V: the colouring and position of the central words indicates the degree to which they are more represented in Literature (more instances).
