Re: [ontolog-forum] Ontology of Commands

[William Frank <williamf.frank@xxxxxxxxx>]

Yes, I agree that the context of the communication is really the center of the story. 

I find that there is an excellent if dusty dry account of context in the Reference Model for open distributed processing, Enterprise Viewpoint, made more accessible in Peter Linngton's Building Enterprise Systems with ODP.  Before any SLA's even apply, there is the question of what kinds of rights the requestor might have to make the request, and the obligations of the provider to grant them, and even before that, how the service provider knows the requestor is who he says he is, and whether he has the attributes required to provide the requested service.

This has been an interesting discussion, with lots of good points made. One observation that I will add is that the concept of command (and SOAs) implies a relationship (part of the command context others have mentioned) between whatever agent(s) is issuing the command (or speech act) and whatever agent(s)/service provider(s) the command is directed at. That relationship constrains the scope of the command, and determines whatever consequence management might be entailed by failure to perform whatever actions are being commanded, including any performance shortfalls (timeliness, completeness, or other quality attributes specified/expected by the command).  That is the major reason for SLA’s in SOAs. It’s also why one of the Net Centric Principles is (explicit and dynamic) relationship management. Note also that relationships have many operative scope dimensions, such as jurisdictional environment (what laws and legal framework(s) apply to the relationship), business models, institutional context(s), if any, social environment (something commanded might be legal but taboo), and operational context(s) in which the relationship and associated command might be applicable/valid.

>From what Leo is saying,

I take the underlying point to be, and it is a critical yet subtle one,

in model theory terms:

the ***model*** is what is really important:  the world we are modelling, where things happen, (events), things persist (whatever you want to call entities or the like), etc. We've *got* to have one of these models, to think with.

A speech act is a kind of event, some actor performs the act.  The propositional content of the act is not part of the type of the event.  A request is an action-- an act in which the requestor asks another actor to do something (this something is not a subtype of request), which other actor has the right to decide whether or not to do, based on the request.  A command is a similar but different action --  an act in which the commander indicates an action that the commanded must perform,  -- the commanded actor is obligated to do as commanded.

The language semantics are the linquistic entities **refering** to the model.  this has things like verbs in it, that generally **refer to** events, and nouns, which might refer to things that we model as events or happenings (perhaps avalanches) or to things we model as persisting (cities).   For example, the particle 'ma' in chinese, the interrogative symbol '?' the interogative facial _expression_ of raising the eyebrows.  All different vocabulary items that refer to the same model element the event of asking.  We might or might not have one or more of these language sematics, separate from the model.

I hope this helps explain the essence of this, in an informal way.

Yes, nouns and adjectives mostly, besides verbs. I think you are better to consider “events”. Almost all verbs, but quite a few nouns and adjectives do denote events. However, those nouns and adjectives are typically based on the verbs. Destroy: destruction : destroyed. They all typically map the same natural language arguments into the verb-based predicates and then to the event denotation.

 

Thanks,

Some (we do) model both the linguistic semantics side (e.g., verbs, etc.)

 

Does "etc" include nouns?

 

What's the ratio between verbs/commands  vs nouns?   Many more nouns than verbs I believe.

 

 

Who/what/how controls the nouns?
