Virtual Workshop on Semantics in Geospatial and Other Architectures: Design and Implementation - Tue 2013-05-07    (3QY4)

This is a virtual workshop organized under an NSF INTEROP Grant by the Spatial Ontology Community of Practice (SOCoP)    (3QY5)

Session Topic: Semantics in Geospatial and Other Architectures: Design and Implementation    (3QY6)

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.    (3R01)

Virtual Workshop on Semantics in Geospatial and Other Architectures: Design and Implementation - [ intro slides]    (3R00)

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.    (3R01)

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.    (3R02)

This virtual workshop may lead to a 2 day in-person workshop in the fall, with possible publication opportunities.    (3R03)

	[9:42] PeterYim: == DouglasFils presenting now ...    (3S58)
	[10:00] GaryBergCross: Good architecture representation in slide 11    (3S59)
	[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.    (3S5A)
	[10:20] DouglasFils: @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..    (3S5B)
	[10:21] DouglasFils: these are just simple SKOS files.. we would really like to leverage off NERC 
	http://www.bodc.ac.uk/products/web_services/vocab/    (3S5C)
	[10:43] MarshallXMa: @DouglasFils: Thanks.    (3S5D)
	[10:02] PeterYim: == DamianGessler presenting ...    (3S5E)
	[10:13] anonymous1 morphed into DanCerys    (3S5F)
	[10:21] PeterYim: @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?    (3S5G)
	[10:22] PeterYim: if the former, do you have a list of your "partners"?    (3S5H)
	[10:25] DamianGessler: @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.    (3S5I)
	[10:29] PeterYim: @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?    (3S5J)
	[10:32] DamianGessler: @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.    (3S5K)
	[10:33] PeterYim: Thank you, Damian    (3S5L)

	[10:23] PeterYim: == DaveKolas presenting ...    (3S5O)
	[10:38] FranLightsom: Can anybody else hear?    (3S5P)
	[10:39] PeterYim: @Fran - yes, I can still hear DaveKolas speaking    (3S5Q)
	[10:41] anonymous1 morphed into FrancescaQuattri    (3S5R)
	[10:42] FranLightsom: Thanks. I needed to redial.    (3S5S)
	[10:45] DaveKolas: Sorry, apparently my sickness resulted in me talking more slowly than usual. 
	Please let me know if you have any questions about GeoSPARQL.    (3S5T)
	[10:47] JohnGraybeal: @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)?)    (3S5U)
	[10:50] DaveKolas: The implementations that exist so far use geospatial indices to improve the 
	processing of the queries, much like rdbms with geospatial extensions    (3S5V)
	[10:50] DaveKolas: So query planning gets a little bit more complicated    (3S5W)
	[10:51] DaveKolas: There are currently 3 implementations of which I am aware (Oracle, Parliament, 
	and Strabon)    (3S5X)
	[10:52] DaveKolas: Our hope is that other triple store vendors who currently have some proprietary 
	spatial extensions (ex, Virtuoso) will eventually support GeoSPARQL    (3S5Y)

	[11:13] PeterYim: relay an anonymous post - URL to SDS Portal http://www.spatial.redlands.edu/sds/    (3S62)
	[11:17] GaryBergCross: Break coming up after Naicong    (3S63)
	[11:17] PeterYim: @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?    (3S64)
	[12:37] NaicongLi: 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".    (3S65)
	[11:21] GaryBergCross: Naicong's updated slides are on the Wiki (with "export" properly labeled now on slide#15).    (3S66)
	[11:24] PeterYim: @PhilipMurphy - possible typo on your email address on slide#28    (3S67)
	[11:35] PhilipMurphy: Peter well spotted! -- should be philip_murphy@spatial.redlands.edu    (3S68)
	[11:36] PeterYim: @Philip ... you might want to send an update of the slides to Gary so he can swap 
	it in for the archives    (3S69)
	[12:04] GaryBergCross: Updated slides for NaicongLi linked to the wiki session page now.    (3S6A)
	[11:31] PeterYim: == [2:31pm EDT] NancyWiegand: we are having break now; resuming in 1 min. ...    (3S6B)
	[11:35] PeterYim: == WenwenLi presenting ...    (3S6C)
	[11:41] GaryBergCross: @WenwenLi - the attribute level looks like a values level.    (3S6D)
	[11:52] anonymous2 morphed into Alex    (3S6E)
	[11:54] PeterYim: == ToddPehle presenting ...    (3S6F)
	[12:10] GaryBergCross: @Todd - Is subset the right way to partition some space?    (3S6G)
	[12:21] ToddPehle: 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)    (3S6H)
	[12:22] ToddPehle: You could also specify these feature types have data in that particular "Country"    (3S6I)
	[12:15] GaryBergCross: @Dave @Todd You 2 need to have a Hackathon on these ideas..    (3S6J)
	[12:17] DaveKolas: @Todd... can you repeat the question you asked about representing CRS's in RDF?    (3S6K)
	[12:24] ToddPehle: 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.    (3S6L)
	[12:25] DaveKolas: 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?    (3S6M)
	[12:29] ToddPehle: @Dave Ok. Will check out the CRS URI...I was referencing an instance of a 
	bounding box (encoded as wkt).    (3S6N)
	[12:31] DaveKolas: So wouldn't a bounding box representation require a crs, and go in there in the normal way?    (3S6O)
	[12:32] DaveKolas: Why do you want it *not* in the literal?    (3S6P)
	[12:32] ToddPehle: Sorry, should have explained better. I was looking for a way to ask "What feature 
	types are in dataset ABC that use EPSG:4326?".    (3S6Q)
	[12:32] DaveKolas: Ah!    (3S6R)
	[12:32] ToddPehle: ...without having to scan every WKT literal to detect.    (3S6S)
	[12:33] DaveKolas: Got it. If there isn't one already, there should be a filter function for getting 
	the crs out of a literal    (3S6T)
	[12:33] DaveKolas: and that could be optimized on the kb side    (3S6U)
	[12:34] ToddPehle: Great. Thanks!    (3S6V)
	[12:24] PeterYim: == ChaoweiYang (Phil) presenting ...    (3S6W)
	[12:25] GaryBergCross: Should slides be advancing?    (3S6X)
	[12:29] PeterYim: @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?    (3S6Y)
	[12:43] PeterYim: @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    (3S6Z)
	[12:39] GaryBergCross: @Chaowei This use of social science methods for developing ontologies / ODPs 
	is a good topic for a future SOCoP workshop.    (3S70)
	[12:40] PeterYim: == NancyWiegand: open Q&A ...    (3S71)
	[12:36] GaryBergCross: BTW Follow on questions and discussion is possible later using the 
	SOCoP Forum http://ontolog.cim3.net/forum/socop-forum/    (3S72)
	[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?    (3S73)
	[12:43] JimJacobs: Many thanks to all the speakers and organizers. Cheers!    (3S74)
	[12:47] GaryBergCross: @Jim - One step in that direction is the deepening modeling of Roles which 
	are social in nature... NicolaGuarino is one source of these ideas..    (3S75)
