Several users have been asking how it is possible to have as object of a hasTopic property something more complex than a URI: a statement or collection of statements.

In order to explain what can be done with AO I am going to use an example: let's say in a document we have a line saying: GeneG encodes ProteinP. What we can do with AO is annotating the single item of the sentence and also encode the sentence itself as a triple (or set of triples).

Figure 1 - Example of annotation of a span of text with something more complex than a URI. A Named Graph has been used to identify the statement of interest. Obviously the graph could include multiple statements when necessary.

Figure 2 - Example of annotation of a span of text with something more complex than a URI. A Named Graph has been used to identify the statement of interest. Provenance shows the annotation has been created by a software and with certainty value. The certainty is declared through the tm:certainty where tm stands for Text Mining, a namespace we are working on with text miners to better accommodate text mining results with AO
