Virtual Workshop on Semantics in Geospatial and Other Architectures: Design and Implementation - Tue 2013-05-07

This is a virtual workshop organized under an NSF INTEROP Grant by the Spatial Ontology Community of Practice (SOCoP)

Session Topic: Semantics in Geospatial and Other Architectures: Design and Implementation

Abstract: This is a virtual workshop focused on the design, use, and software development of semantic technology in geospatial and other architectures. Semantic technology can encompass ontologies, repositories, mappings, reasoners, and other components as well as linked data. A purpose of the workshop is to identify current systems using semantic technologies, learn why semantics were needed, describe and analyze how those systems are built (i.e., what technologies are being used both conceptually and in software development), identify commonalities in concept and software to possibly develop re-usable software templates, and identify unmet needs for future architectures, both for functionality and then software. The use of semantics can be for searching, data integration, question answering, or other needs, considering both research and implementation. One of the purposes is to gain examples of how to include semantic technology in, for example, geospatial portals, statewide information systems, spatial data infrastructures (e.g., NSDIs) database systems, and so on. Because the use of semantics in the geospatial area is still relatively new, other domains and applications are of interest.

Abstract

Virtual Workshop on Semantics in Geospatial and Other Architectures: Design and Implementation - [ intro slides]

This is a virtual workshop focused on the design, use, and software development of semantic technology in various geospatial architectures. One of the purposes is to gain examples of how to include semantic technology in, for example, geospatial portals, statewide information systems, spatial data infrastructures (e.g., NSDIs) database systems, etc. Because the use of semantics in the geospatial area is still relatively new, other domains and applications are also of interest. Semantic technology can encompass ontologies, repositories, mappings, reasoners, and other components as well as linked data.

In particular, the purpose of the workshop is to identify current systems using semantic technologies, learn why semantics were needed, describe and analyze how those systems are built (i.e., what technologies are being used both conceptually and in software development), identify commonalities in concept and software to possibly develop re-usable software templates, and identify unmet needs for future architectures, both for functionality and then software. The use of semantics can be for searching, data integration, question answering, or other needs, considering both research and implementation.

This virtual workshop may lead to a 2 day in-person workshop in the fall, with possible publication opportunities.

[10:00] GaryBergCross: Good architecture representation in slide 11

[10:07] MarshallXMa: @DouglasFils: Can you list a few example vocabularies used in your works. You

mentioned vocabularies are important on slides 4 and 10 of your presentation. thx.

[10:20] Douglas Fils: @MarshallXMa: I am working to get our current vocabularies update into the web

service.. some of the older versions are at http://data.oceandrilling.org/core/ We will try and use

the w3c patterns for sharing the current vocabularies soon..

[10:21] Douglas Fils: these are just simple SKOS files.. we would really like to leverage off NERC

http://www.bodc.ac.uk/products/web_services/vocab/

[10:43] MarshallXMa: @DouglasFils: Thanks.

[10:02] Peter P. Yim: == Damian Gessler presenting ...

[10:13] anonymous1 morphed into Dan Cerys

[10:21] Peter P. Yim: @DamianGessler - does enabling a site to serve the data need to be done on the

server side by the website provider, or will an enabled client be able to do it on any website?

[10:22] Peter P. Yim: if the former, do you have a list of your "partners"?

[10:25] Damian Gessler: @PeterYim - data providers host a SSWAP OWL RDF/XML graph for each service

they offer. This "graph" describes their service semantically, allowing for discovery and

(automated) engagement.

[10:29] Peter P. Yim: @DamianGessler - since your technology is quite domain independent, do you have

plans to apply that to other domains beyond "plants" (if so, what domains are being worked on or

considered?

[10:32] Damian Gessler: @PeterYim - geo would be natural (esp. because the of the scientific overlap

between bio/geo/plant research). But no firm plans yet; open to follow-up. You are correct that the

core technology is domain independent.

[10:33] Peter P. Yim: Thank you, Damian

[10:22] anonymous2 morphed into Paul Koch

[10:23] anonymous1 morphed into Todd Pehle

[10:23] Peter P. Yim: == Dave Kolas presenting ...

[10:38] Fran Lightsom: Can anybody else hear?

[10:39] Peter P. Yim: @Fran - yes, I can still hear Dave Kolas speaking

[10:41] anonymous1 morphed into Francesca Quattri

[10:42] Fran Lightsom: Thanks. I needed to redial.

[10:45] Dave Kolas: Sorry, apparently my sickness resulted in me talking more slowly than usual.

Please let me know if you have any questions about GeoSPARQL.

[10:47] John Graybeal: @Dave: It was a very nicely put together summary of the technology, very neat

to follow. What are the implications on the inference engine of having to satisfy geospatial

relation queries? (How many support it, are they very much optimized (yet)?)

[10:50] Dave Kolas: The implementations that exist so far use geospatial indices to improve the

processing of the queries, much like rdbms with geospatial extensions

[10:50] Dave Kolas: So query planning gets a little bit more complicated

[10:51] Dave Kolas: There are currently 3 implementations of which I am aware (Oracle, Parliament,

and Strabon)

[10:52] Dave Kolas: Our hope is that other triple store vendors who currently have some proprietary

spatial extensions (ex, Virtuoso) will eventually support GeoSPARQL

[10:53] anonymous1 morphed into Alex Mirzaoff

[11:07] Peter P. Yim: == Naicong Li presenting ...

[11:13] Peter P. Yim: relay an anonymous post - URL to SDS Portal http://www.spatial.redlands.edu/sds/

[11:17] GaryBergCross: Break coming up after Naicong

[11:17] Peter P. Yim: @NaicongLi & PhilipMurphy - for the "collected" tools and models, are you working

with those from your collaborators/partners or are they "discovered" from publications and the web?

[12:37] Naicong Li: Peter -- I just saw your question earlier - "for the "collected" tools and

models, are you working with your collaborators/partners or are they "discovered" from publications

and the web?" The answer is "both".

[11:21] GaryBergCross: Naicong's updated slides are on the Wiki (with "export" properly labeled now on slide#15).

[11:24] Peter P. Yim: @PhilipMurphy - possible typo on your email address on slide#28

[11:35] PhilipMurphy: Peter well spotted! -- should be philip_murphy@spatial.redlands.edu

[11:36] Peter P. Yim: @Philip ... you might want to send an update of the slides to Gary so he can swap

it in for the archives

[12:04] GaryBergCross: Updated slides for Naicong Li linked to the wiki session page now.

[11:31] Peter P. Yim: == [2:31pm EDT] Nancy Wiegand: we are having break now; resuming in 1 min. ...

[11:35] Peter P. Yim: == Wenwen Li presenting ...

[11:41] GaryBergCross: @WenwenLi - the attribute level looks like a values level.

[11:52] anonymous2 morphed into Alex

[11:54] Peter P. Yim: == Todd Pehle presenting ...

[12:10] GaryBergCross: @Todd - Is subset the right way to partition some space?

[12:21] Todd Pehle: Hi Gary, VoID subsets are generic ways to partition a dataset (not so much a space);

One obvious use for this is finding the download URL of an RDF file by "Country" (say in Geonames dataset)

[12:22] Todd Pehle: You could also specify these feature types have data in that particular "Country"

[12:15] GaryBergCross: @Dave @Todd You 2 need to have a Hackathon on these ideas..

[12:17] Dave Kolas: @Todd... can you repeat the question you asked about representing CRS's in RDF?

[12:24] Todd Pehle: Dave, I wanted to use geosparql:asWKT to describe BBOX; as I understand it, CRS

is specified inside the geometry literal...is this correct? I was hoping I could directly assert CRS

in RDF with geosparql vocab.

[12:25] Dave Kolas: The CRS only lives in the literal in GeoSPARQL, but you could potentially

reference its uri with a different property... I'm not sure what you mean about using asWKT to

describe BBOX? Do you mean an instance of a bounding box, or the concept of bounding boxes?

[12:29] Todd Pehle: @Dave Ok. Will check out the CRS URI...I was referencing an instance of a

bounding box (encoded as wkt).

[12:31] Dave Kolas: So wouldn't a bounding box representation require a crs, and go in there in the normal way?

[12:32] Dave Kolas: Why do you want it *not* in the literal?

[12:32] Todd Pehle: Sorry, should have explained better. I was looking for a way to ask "What feature

types are in dataset ABC that use EPSG:4326?".

[12:32] Dave Kolas: Ah!

[12:32] Todd Pehle: ...without having to scan every WKT literal to detect.

[12:33] Dave Kolas: Got it. If there isn't one already, there should be a filter function for getting

the crs out of a literal

[12:33] Dave Kolas: and that could be optimized on the kb side

[12:34] Todd Pehle: Great. Thanks!

[12:24] Peter P. Yim: == Chaowei Yang (Phil) presenting ...

[12:25] GaryBergCross: Should slides be advancing?

[12:29] Peter P. Yim: @Phil - ref. your slide#7 ... are your planning to stand up your own ontology

repository; if not, what/who are the ontology repository people you are planning to work with?

[12:43] Peter P. Yim: @Chaowei - please look at what we are doing in the OOR Initiative

- see: http://oor.net ... and in particular the SOCoP instance at: http://socop.oor.net

[12:39] GaryBergCross: @Chaowei This use of social science methods for developing ontologies / ODPs

is a good topic for a future SOCoP workshop.

[12:40] Peter P. Yim: == Nancy Wiegand: open Q&A ...

[12:36] GaryBergCross: BTW Follow on questions and discussion is possible later using the

SOCoP Forum http://ontolog.cim3.net/forum/socop-forum/

[12:38] GaryBergCross: Any thoughts out there on the value and interest in a workshop on this in the

Fall? Who would be interested in coming?

[12:43] Jim Jacobs: Many thanks to all the speakers and organizers. Cheers!

[12:47] GaryBergCross: @Jim - One step in that direction is the deepening modeling of Roles which

are social in nature... Nicola Guarino is one source of these ideas..
