bullet point - Wants are getting a little ahead of wishes, as usual :(

What people already believe about Linked Data is that {an SQL  right outer join 
of Category Name Elements on Topic Name Elements in a homogeneous name space - 
e.g. counts grouped by Category Name} is a unique vector. SQL has fewer shades 
of promiscuity than SPARQL.

This is not a commercial deal breaker ... rather:  a long ago verbal contract, 
possibly signed under duress, with your Second Grade Teacher.  When she said 
"2+2=4" although substantiation would forthcoming, her work product was 
guaranteed against material defects.  The contract is still in effect, 
world-wide.  No Nobel Prizes to be had here.  Wolfgang Pauli already won - The 
Pauli Exclusion Principle means that "2+2=5" is, in Pauli's words, "Not Even 
Wrong !!!".  Little justice in the prize judging, BTW.  Nuns (I had Dominicans) 
have been communicating the same message for centuries. Mistakes were made.  
Knuckles jumped in front of wooden rulers on a regular basis, etc. :)

Ruben ... 
"One of the main problems I see is how our community  (now particularly 
thinking about the scientific subgroup) receives submissions of novel work."

I think ...
Maybe the problem is the identification of "novel work".  Interoperability can 
depend on the novel nature of the work or Induced Knuckle PTSD. Just a guess, 
but not many Software Patents mention Nuns or knuckles.  Somebody might do a 
survey though.

Ruben ...
" We have evolved into an extremely quantitative-oriented view, where anything 
that can be measured with numbers is largely favored over anything that cannot."

I think ...
True enough.
In addition ...
1) The arbiters of taste (paying customers) went to Second Grade, and in 
subsequent steps the first professional trick they learned was writing a annual 
balance sheet. Content: (12 Monthly Values) (4 Quarterly sums) (1 Annual sum)

2) All of us folk, OTOH, may have encountered von Neumann Architecture first.  
A balance sheet is not von Neuman Architecture.  The 17 pigeon holes are 
"smart" or so you evangelize, but all will be for naught if you relabel the 
pigeon holes.   Actually, the birds won't care, but you will unsettle the 
pigeons mightily because they consider von Neumann Architecture a disruptive 
technology, and always will. 


It just seems to me that - knowing that web discovery is prone at least 17 
pigeon hole misdemeanors and probably all seven deadly sins as well -  it is 
wise to proceed stepwise before accepting the web of things identification of 
reputable brands of truth.

Some English guy said it a whole lot better, BTW ...

 Hi,
 
 This is a very important question for our community,
 given that smart agents once were an important theme.
 Actually, the main difference we could bring with the
 SemWeb
 is that our clients could be decentralized
 and actually run on the client side, in contrast to others.

 (now particularly thinking about the scientific subgroup)
 receives submissions of novel work.
 We have evolved into an extremely quantitative-oriented
 view,
 where anything that can be measured with numbers
 is largely favored over anything that cannot.
 
 Given that the smart agents / bots field is quite new,
 we don't know the right evaluation metrics yet.
 As such, it is hard to publish a paper on this
 at any of the main venues (ISWC / ESWC / …).
 This discourages working on such themes.
 
 Hence, I see much talent and time going to
 incremental research, which is easy to evaluate well,
 but not necessarily as ground-breaking.
 More than a decade of SemWeb research
 has mostly brought us intelligent servers,
 but not yet the intelligent clients we wanted.
 
 So perhaps we should phrase the question more broadly:
 how can we as a community be more open
 to novel and disruptive technologies?
 
 Best,
 
 Ruben

Melvin,

I don't know if you are aware of Hubot [1]? Basically, its a platform
that certainly looks interesting from the following perspectives:

Hi Ruben,

On my part, I am really pinging the community (due to deafening silence)
about a pendulum swing back to its fundamental strengths--structured
data (represented as sentences) endowed with machine- and
human-comprehensible entity relationship type semantics.

Eons ago (Semweb time) use of various Bots (Jenni [1], Micro Turtle [2],
Phenny [3], and friends) on IRC channels was the norm. Those agents were
early Semantic Web utility demos confined to IRC rather than the broader
Web.

Twitter and Slack are just pretty looking modern variants of what IRC
delivers, as most folks in this community certainly already know.

Today, we have an opportunity to rehash, recast, port, or build new bots
performing the very same tasks, but across a Web of (Linked) Data.

Fundamentally, mercurial GUI oriented UI/UX should be less of a hurdle
to Linked Data and Semantic Web utility showcases. Why? Because bot
interactions are predominantly about conversational interfaces that
ultimately depend on the ability to process information encoded using
sentences, and In RDF (the Language) we have the ultimate tool for
compact sentence representation :)

Re: Where are the Linked Data Driven Smart Agents (Bots) ?

[Pieter Colpaert]

Hi Kingsley,

Not a perfect answer to your question as it is in a very early stage, 
yet I'm trying to develop an intelligent agent to give you route 
planning results across transit networks: Linked Connections [1]. By 
following links and discovering various other data sources, it can take 
into account user-specific requirements. E.g., wheelchair accessibility 
information about stations or buses from other sources can be taken into 
account without the server itself exposing this functionality.

I also think this is the way forward, and would like to see such bots

My intuition tells me that knowledge is valuable.  Smart bots enable

Re: Size a linked open data set

[Nandana Mihindukulasooriya]

Dear Jean-Claude,

I'm not sure exactly what you meant by the "number of distinct resources in
a dataset". Is it "the total number of distinct subjects" including both
IRIs and blank nodes? It seems your first query counts that. Your second
query seems to count the number of triples in the dataset. You can also
count total number of distinct resources or IRIs taking into account
subject, predicate, objects of all triples. The VoID vocabulary defines
some of those statistics. https://www.w3.org/TR/void/#statistics

Loupe, a tool that we built to explore datasets, provide some of those
statistics for the DBpedia (FR) 2015-04 dataset.
http://loupe.linkeddata.es/loupe/summary.jsp?dataset=frdb

At the moment, we are creating a new version with DBpedia 2015-10 datasets
and we will be happy to share those statistics with you in advance. Please
feel free to contact us if you don't find the information you need in the
current online version.

Size a linked open data set

[Jean-Claude Moissinac]

Hello

In my work, I need to know the number of distinct resources in a dataset.
For example, with dbpedia-fr, I'm trying
select count(distinct ?r) where { ?r ?p ?l }

And I'm always getting a timeout error message
While with
select count(?r) where { ?r ?p ?l }
I'm getting
185404575

Is it a good way to know about such size?
