Joslyn, Cliff: (2000) "Hypergraph-Based
Representations for Portable Knowledge Management
LANL Technical Report LAUR 00-5660,
Joslyn is thinking along v. similar lines to us, essentially
arguing for weighted conceptual graphs as the fundamental underlying
representation for a "DKS" (Distributed Knowledge System), that can be
rendered in multiple ways (cf. Eugene's paper)
Conjecture 6: Each
semantic hyperweb determines a unique conceptual graph. Conversely,
conceptual graph determines a class of semantic hyperwebs equivalent
basically states that a cg is equivalent to an unweighted semantic
The issues where we
part company with cgs include:
Semantic webs are
The bipartate representation of a cg echoes the \tentacle"
representation of a hypergraph.
The difference is
that all the tentacles together comprise a single hyperedge, whereas
these have to be called out distinctly.
Similarly, hypergraphs are closer to the typed-link hypertext model.
Here now only concepts
are represented as
vertices, and relations of different types are assigned edges of
resulting in a labeled or multigraph mathematical
He also refers to work that connects with the graph tool reqts
First, there is a
need for a general, robust front end, not something highly specialized
like the Java
Ontology Editor (JOE) , or Protege . The following features
drawing/visualization environment for both simpler node-arc diagrams
and more com-
plex hypergraph form.
A professional GUI: full undo/redo, a full audit trail (time
stamping, authoring, versioning),
graphical and textual annotation, etc.
Building on commercial platforms for graph editing and on supported
protocols both at the
intersection of graph markup and KR.
Recent work at LANL
collaboratively with the University of Liverpool has begun
building from the Visio platform for Windows. Visio is a superb
environment for working with
reasonably sized labeled graphs, and can be adapted to the tentacle
representation of hypergraphs
