COMA
CC
Line-based
representation of matchings.
Tree-based
representation of ontologies.
Strength
of correspondence (number
between zero and one). Line color
indicates similarity strength
Plugin support
for
matching
algorithms
A variety of automatic
matchers
P
ROMPT
List
representation of matchings.
Tree-based
representation of ontologies.
Interaction is
synchronized
with the
source and target ontology trees.
Strength
of correspondence (description
of the “reason for suggestion”)
Extensive

architecture
Default algorithm is
lexical based.
Verification of a
correspondence is
used to infer new
suggestions
C
OG
Z
Line-based
representation of matchings.
Tree-based
representation of ontologies.
Interaction is
synchronized
between
search, ontology browsing, and
correspondence browsing.

correspondence (description of the
“reason for suggestion”)
AlViz
Tree-based
representation of ontologies.
Small world graphs
representation of
matchings. Interaction
synchronized
with Protege class browser. Color is
used to represent the types of
correspondences (e.g., equal, similar,
broader than). The cluster display can be
filtered by selecting particular entities in
the source
No pluggable
architecture
FOAM algorithm
OLA
Graph-based
visualization of ontologies.
The source and target ontologies can be
compared side by side. Interaction
synchronized
between the two ontology
displays
No pluggable
architecture
A custom algorithm
that combines
similarity metrics
based on lexical
similarity,
neighbor node
similarity, and
descriptive features
Muse
Interaction based on
wizards
that help a
user disambiguate matching
correspondences
No pluggable
architecture
A custom algorithm
that incorporates
user feedback and
automatically
generates questions
and examples for
the user
OntoMap
Drag and drop, line-based
representation
for matchings.
Filters for data
transformation
can be created
interactively based on a particular
matching correspondence
No pluggable
architecture
Does not support
automatic
generation of
matchings
