Abstract. Network of ontologies is the pairwise match of a set of ontologies, which be-
came recently relevant due to its applicability in different domains, such as cultural evo -
lution. However, the challenges faced in this area are not completely known and under-
stood, neither are their relations to ontology matching counterpart problems. The goal
of this paper is to identify challenges and applications of a network of ontologies and
compare them to the 8 existing challenges of ontology matching. We identified four new
challenges and related them with the eight challenges presented in [3].
Keywords: Ontology, Ontology Alignment, Network of Ontologies, Systematic
Mapping Study.
1 Introducing research challenges on Network of Ontologies
After years of research and work on the Ontology field, different ontologies for de -
scribing the same domain of discourse were developed, either from scratch or based
on existing ones. To deal with a number of distinct ontologies for the same domain,
various Ontology matching systems were developed towards improving the process of
aligning ontologies in a pair wise manner. The field of Ontology Matching evolved
significantly; yet, some challenges still remain, as highlighted in [3].
With the advances on matching techniques, a network structure naturally arose,
composed by the set of discovered alignments and their respective ontologies. The
network environment brings new tasks that were not necessary when we were dealing
with single or pairs of ontologies. So to explore the network of ontologies issues, and
try to understand the relation with the matching problems, we performed a systematic
mapping study and compared the challenges we have found with the challenges pre -
sented in [3]. The complete study and its results are detailed in [5].
Network of Ontologies (N.O.) is a set of ontologies with a set of alignments be-
tween them [1], or a set of theories linked by different kind of relations [2]. At some
point, an application may look for alignments options in a network or a network has
to be maintained with supporting tools.
We investigated, through a systematic mapping study, a research question of " How
similar is the N.O. alignment task when compared to the ontology matching" ? We
have identified four challenges: network consistency detection, network revision and
repair, network creation and management and inter-network matching. The first two

were mentioned in the articles selected and the last two were inferred by the N.O. def -
initions presented in some articles.
Figueroa et al. [4] presented a methodology to build ontologies and a tool to man -
age lifecycles. However, the approach does not address the definition of activities re-
lated to N.O. administration including user access and rights, node management, net-
work troubleshooting and other typical activities in network environments. These
problems were also not covered in [3]. If we relate the known research areas in [3] to
the four “new” challenges we found after this systematic mapping, as illustrated in
Figure 1, we may reveal some characteristics of the challenges.

2 Final Considerations
This work provides a first roadmap for research on Network of Ontologies, by point-
ing a set of challenges found through the use of a systematic mapping in the literature.
Interestingly, the identified challenges interrelate to previous Ontology Matching
challenges posed in [3] by addressing overlapping research areas. Moreover, the new
challenges found also transcend previous one with regard to specific issues such as
consistency detection and alignment repair.
