Semantics In Kepler

Difference between version 15 and version 14:

Line 20 was replaced by line 20
- We intend to use ontology-driven search capabilities to improve discovery capabilities for both data and actors that have been annotated with terms from formal ontologies. For both actors and data, there are two levels of annotation that we will make use of. The first level is an annotation that addresses the general topic of the data or function of the actor. We can call this the "topical ontology annotation". The second level is another annotation that describes the semantic signature of the data or actor. We can call this the "signature ontology annotation". In the case of data, these annotations describe the semnatic type of each attribute within the data and (possibly) how the attributes relate to one another. For actors, this describes the semantic type of each input and output port and (possibly) how the ports relate to one another. The topical ontology annotation is meant to describe generally what something represents or does, while the signature ontology annotation describes the encoding of meaning by the data or actor. In some cases, the signature ontology annotation may be used to "infer" the topical ontology annotation.

For actors, signature annotations describe the semantic type of each input and output port and (possibly) how the ports relate to one another. The topical annotation is meant to describe generally what something represents or does, while the signature annotation describes how such semantic information is encoding (i.e., realized) by the data or actor. In some cases, the signature annotation may be used to "infer" the topical annotation.
