Task Ontology is a specification or detailed description of elements and relationships of tasks to explain how tasks can exist and be used in a specific field or environment. It is a general term used to describe a set of definitions and concepts regarding tasks.
Task ontology uses a systematic approach for specifying tasks and describing their existence. It serves as a foundation for using tasks in a certain field. For instance, in the field of management task ontology defines what a task means, what elements it has, and what relationships with other tasks can be established. It causes the discipline of task management.
Task ontology is not just a way to specify or describe a task in essence. It is a method of creating a model of existence and use for a task. There’re several criteria that determine how such a model can be designed:
- Clarity. Every single task is clearly defined and stated so for anyone it is easy to understand the task.
- Coherence. All tasks are consistent with their definitions.
- Extendibility. Existing definitions of tasks can be extended or supplemented with new terms, expressions and other relevant information, but in the way that does not eliminate, contradict or neglect the definitions.
