As we have seen, there are various knowledge resources that can be used in the conservation and promotion of cultural heritage in the context of the semantic web.
The reuse of these preexisting resources increases data quality and improves interoperability with other projects. Several factors determine the way in which these resources must be used in the proposed solution. For example, the level of detail that should be represented in the context of a project, the questions that the project needs to respond to, the level of interaction with other projects in the domain, the user’s level of expertise and his information needs, the nature of the domain, and the terminology used.
There are certain general principles, however, that can be considered to ensure a better solution. For instance, concealing the complexity and ontological structure, using concrete instances and concepts instead of abstract semantics, domain experts and computer scientists participating in the proposed solution, using informal semantics to explain modeling decisions, and exchanging experiences and results with the community in the domain in question.
In combination with these principles, there are several techniques in the context of the semantic web that should be taken into consideration to guarantee a state-of-the-art solution, such as natural language processing, information extraction, semantic similarity and ontology alignment.
The extension of cultural heritage ontologies to represent specific semantics in the context of the project is essential for the improvement of interoperability, the satisfaction of the user’s information needs, and the contextual, spatial and temporal enrichment of data. This contributes greatly to the conservation and promotion of cultural heritage in the context of the semantic web.
