One of the core features of ConceptMap is the synchronized navigation
between Wikipedia articles and their Wikidata semantic relationships.
In the brief video, for example, the Wikipedia article named "David
Bowie" is displayed in the rightmost panel. The semantic relationships
defined in Wikidata for David Bowie (whose Wikidata identifier is
"Q5383") are displayed in the center panel. The user can see the items
related to David Bowie (e.g. All the Young Dudes), as well as the
relevant Wikidata properties (e.g. performer). When the user clicks on
a related item, the Wikipedia article for that item appears in the
rightmost panel. Conversely, when the user clicks an article link in a
Wikipedia page, the center panel is updated to show the relationships
defined in the Wikidata item corresponding to that article. This
synchronized navigation feature enables the user to explore areas of
interest using an approach that combines structured (Wikidata
relationships) and freeform (Wikipedia links) navigation.
Another core feature of ConceptMap is the dynamically created directed
graph in the leftmost panel. When a Wikipedia article is displayed and
its corresponding Wikidata item appears in the title area, the "Pin
item" checkbox may be used to pin/unpin the item from the concept map.
Each of the pinned items appear as labeled circles (nodes) in the
concept map. As items are added to the graph, relationships from
Wikidata are displayed as labeled lines (links) between the nodes.
As shown in the video, the Wikidata icon in the upper right portion of
the page opens the Wikidata page for the selected item. This is useful
for adding missing relationships to Wikidata, as shown in the video
when adding "space rock" to the list of genres for his song entitled
Space Oddity. To share or bookmark a concept map, click the button
with the link icon as shown in the video. A shortened URL appears that
you can copy.
In future posts I plan to share details of the technologies and code
involved in creating this application. In the meantime, whether you
are a learner, researcher, teacher, or all of the above, I hope that
you'll take it for a spin!
