Presentation transcript:

Ontology: Philosophy vs. IT Similarities: Both require careful study/analysis of what exists i.e., conceptual modeling Objects: concrete/abstract, real/ideal, [in]dependent Relationships: dependencies, properties Both document the output of the study/analysis: in ‘natural language’ as a logical theory for sharing and reuse in a larger community. 30s Caveats: Not all philosophers use logic… Natural language is the "only tool a philosopher has". Traditionally, they read their talks, word for word at a conference, say. Less true these days. Culturally shocking, like burping after a meal….

Ontology: Philosophy vs. IT Similarities: Both use natural language as a source of knowledge to reveal the objects and relationships of interest. Both use formal logic as a key analytical tool. 30s Caveats: Not all philosophers use logic…

Ontology: Philosophy vs. IT Differences: Purpose Ph: The end: an understanding of the world Why: “because its there” IT: The beginning: an understanding of the world The middle: a machine-sensible model The end: a software application that does something useful Why: because it helps the bottom line Range of specific purposes … 30s

Ontology: Philosophy vs. IT More Differences: Ph: Grammatically, not countable vs. IT: Can have one or more ‘ontologies’; Ph: Subject area extremely general vs. IT: Focused on a specific domain (usually); Ph: Main focus is on what is, ultimate truth vs. IT: What is useful or important in a specific context; Ph: Source of knowledge is the world itself vs. IT: experts, books, etc in a given field of study. 30s Differences: Output of the study/analysis

Ontology: Philosophy vs. IT More Differences: Output of the study/analysis Ph: Natural language output is a formal academic paper vs. IT: may be a paper, or may just be informal documentation; Ph: Computational output, None (historically) vs. IT: Machine-sensible model to support computer processing browsing and search automated reasoning and inference . Varying degrees of formality 30s NB: some philosophers are now doing building ‘IT ontologies’
