HuViz Glossary
Activate
Pulls node into central graph.
Class
Classifies nodes according to type, such as: Organization, Person and SpatialThing.
Current Command
Verb and Set/Class types in current operation are displayed here.
Discard
Removes nodes from the central Graph or Shelf and sends to Discard Bin, represented as
a red dot at the bottom-right of the Stage.
Edge
A connective link between two nodes, signifying a relationship.
Edges of the Selected Nodes
Classifies the relationship between two nodes; expressed as the Predicate + Object
section of the triple. For example, hasLivedConenctiontoOrganization.
Graph
Contains Active (graphed) nodes; located inside the circular Shelf.
Hide
Temporarily removes nodes from the dataset.
Hub
The central node in a network. The Hub node represents the subject in a
Subject-Predicate-Object RDF triple. Hub nodes are automatically dragged into the graph when
an object is Activated.
History
A record of the user's actions in the graph. The Command History can be used to undo
and redo actions, as well as save and re-open previous sessions.
Label
Displays the node name.
Node
A unit, such as a person, place or spatialThing, which is connected to other units.
Subjects and Objects in RDF triples are visually represented as nodes.
Pin
Fixes nodes in place.
Predicate
A statement signifying the relationship between a subject and object .
Reset
Erases commands, restoring graph to default.
Retrieve
Retrieve nodes from the Discard Bin and return them to the shelf.
Resource Description Framework (RDF)
A set of rules established by the World Wide Web Consortium (W3C) used for governing
the semantic web. Data is linked together through statements known as "triples" that describe
information in terms of subject-predicate-object relationships.
Script
Records the sequence of commands which were performed to produce the current state of
the display.
Select
Selects node to execute a command when used in combination with a Verb.
Stage
Visual representation of the dataset, containing the three main areas: central Graph,
Shelf and Discard Bin.
Toolbox
Contains the Help, Settings, Commands and Script tabs.
Shelve
Removes nodes from the central Graph or Discard Bin and returns to Shelf.
Shelf
Where deactivated (ungraphed) nodes are housed, represented as a green circle
surrounding the central Graph.
Set
Classifies nodes according to current state, such as: Activated, Discarded,
Graphed.
SPARQL
A query language used to search for and generate a dataset from a database; as opposed
to using a dataset that has been pre-loaded from a turtle file.
Triple
Formal statement describing a relationship in terms of a
subject-predicate-object.
Walk
In "walk-mode," every node you click becomes the central node in the graph. Nodes
immediately connected to it will be draw into the graph. Previously clicked nodes will turn
black and remain in the graph, preserving a record of the user's "pathway."
Wander
In "wander-mode," every node you click becomes the central node in the graph. Nodes
immediately connected to it will be drawn into the graph. All other nodes will be shelved.
Unlike in "walk-mode," the user's pathway is not preserved.
