As its name indicates, there are no cycles between the nodes of a DAG, and its edges have a one-way meaning. This allows classifying the DAG nodes in top-level, mid-level, and bottom-level nodes, where the level denotes the grade of specialization of each node, being upper-level nodes...
being polynomial in the number of triples and NP-complete in the size of the query in the worst case. OWL Lite is much more difficult, requiring exponential time in the number of triples for the worst case. OWL-DL isdecidable, meaning that the processing will finish in a finite amount ...
These issues encourage the development of an ontology that defines consistent terms to benefit knowledge exchange in this domain. Ontologies are software artifacts that represent domain knowledge using terminologies and taxonomic relations to express domain meaning. By describing and linking concepts together...
In my opinion, it would be worthwhile to have the definitions of inconsistency, incoherence, unsatisfiability, validity, etc. written somewhere (at least in the glossary of OBO Academy) so that we can all refers to the same meaning of the terms. matentzn added the newsletter label Jun 7, ...

In “Teleology and Camoflage”, Land points at the odd implications of “teleonomy” in biology, meaning “mechanism camouflaged as teleology”. Teleonomy appears in biology as a way to talk about things that really look teleological, without admitting the metaphysical reality of teleology. But ...
The term “ontology” was originally used in the field of philosophy, meaning “the essence of things, itself”, and the abstract nature of real things. Others describe ontology as: “Ontology defines the relevant terms in the field, associations and rules of domain lexical epitaxy”. Ontology...
Skip forward 20 years and its meaning has been diluted in the haze of its own hyperbole and is often blurred by techno-optimistic visions of ‘smartness’. The term applies at all scales, from wearables like smart watches, to IoT-enabled homes or cars, right through to entire smart cities...
Not long ago, the term ‘ontology’ took on a new meaning in the context of computer science. In the late 1980s and early 90s, Artificial intelligence was attempting to create large maps of human understanding, and the term “ontology” started to creep into general use in AI circles. ...
Secondly, a semantic similarity is used to compute the extent of similarity between the term pairs regarding the likeliness of their meaning. This opens the door to exploring WordNet as a way of finding semantic similarities, since WordNet can determine the semantic distance between two terms’ ...
