I'm working on a research project to develop an ontology for wetlands in PROTEGE, but I have doubts about the relationship between ontologies and knowledge management, I understand that ontologies are used for the representation of knowledge, but I can not find an academic text about the relationship between ontologies and knowledge management, specifically I find information on knowledge management.
There are a lot of different definitions of "ontology" out there. In my opinion this here is highly relevant in practice:
An ontology is a formal, explicit specification of a shared conceptualization.
See this article for a formal discussion (ignore the "math", read the text).
Therefore the most interesting questions in creating an ontology is, which competency questions (see the section in ontology development 101) do you want your model or knowledge base to answer?
That settled, what does it have to do with knowledge management?
Wikipedia defines Knowledge Management as:
Knowledge management (KM) is the process of creating, sharing, using and managing the knowledge and information of an organisation.
So ontologies can only be a tool in knowledge management (KM). So how do they help with KM?
Wherever you annotate data with terms from your ontology, it becomes more findable, accessible, interoperable and re-usable (see FAIR data principles) for humans and machines alike.
In addition it is easier to connect your data with other information (they facilitate data integration).
