Moving Forward with Semantics for Earth Science Data - intro slides    (3IXH)

This is the 5th and final session of the Joint EarthCube-Ontolog Mini-series on "Ontology and Semantic Technology for the Earth Science Community" - a series of panel sessions dubbed: "EarthScienceOntolog" - an Earth Science Ontology Dialog.    (3IXI)

This mini-series of events are co-organized/supported by members of the EarthCube community, Ontolog community, SOCoP community, IAOA community.    (3IXJ)

We will continue the mini-series process (see kick-off session abstract) with the aim of enabling meaningful dialog between members of both communities (Earth Science and ontology/semantics). To this end we seek to further an understanding of Earth Science system requirements expressed in such things as use cases, geo-science identified problems and issues, extant system architectures and their lifecycles, the status of relevant ontological engineering, architectures and approaches, and prospective tools.    (3IXK)

In this last session of the Earth Science Ontology Dialog mini-series, we will start by discussing the building blocks for the EarthCube program. That will be followed by two tutorials - one on semantic technologies, ontologies, and the Web Ontology Language (OWL); the other on GeoSPARQL.    (3IXL)

At the end, the mini-series is summarized with some discussion on next steps in working toward semantics for Earth Science data.    (3J4N)

Briefings:    (3I6H)

Abstract: ... EarthCube building blocks are components of an overarching architecture designed to support objectives of EarthCube identified by National Science Foundation (Jacobs[1], 2012; Killeen[2], 2012), as well as those highlighted in the European Commission report Riding the Wave;    (3IXO)

o Data publication and access: developing new technologies to enable individuals and large data centers to publish data, as well as enabling access through semantic technologies. These technologies must be coupled with a reward system to encourage data sharing.    (3J4S)

o Collection: develop community endorsed simple metadata requirements for data providers to facilitate access to both curated as well non curated data    (3J4T)

o Diversity: provide capabilities to access and discover heterogeneous resources    (3J4U)

o Interoperability: provide capabilities (semantic as well as syntactic ) to understand the content of databases, as well as support discovery of resources beyond keyword searches    (3J4V)

o Trust: provide innovative algorithms to enhance users trust of data they are unfamiliar with, as well as management of resources to enhance trust in the source of the data    (3J4W)

o Security: New technologies to enhance data integrity, as well as capabilities to detect data biased by a group or individual    (3J4X)

o Education and training: New capabilities to generate interest in geoscience through training of data scientists and librarians, as well as providing capabilities to bring information to a class room setting    (3J4Y)

o Usability: Provide new technologies to enable non-specialists to use data, as well as scientists to work with unfamiliar data    (3J4Z)

o Preservation and Sustainability: Develop capabilities to preserve current data, as well as legacy data    (3J50)

o Commercial exploitation: Utilize commercial developments to enable revenue generation for sustainability of resources    (3J51)

To meet such objectives, synergy between science and informatics is required to develop a more robust understanding of the earth as a system of systems. Interaction of these systems is recorded in both geological and biological data, yet the capability to integrate across disciplines is hampered by diverse social and technological approaches to research and communication. A significant challenge that must be met in order to promote such an understanding encompasses the integrated development of social, engineering and science based infrastructures.    (3J52)

	[10:32] LeoObrst: @Dave: I see on slide 13 that at least some of the Region Connection Calculus 
	(RCC) axioms are supported. Are these actually expressed in detail usable by a reasoner?    (3JL6)
	[10:33] DaveKolas: Leo: They are not usable by a OWL-SWRL style reasoner (qualitatively) at the 
	moment.    (3JL7)
	[10:33] DaveKolas: Current implementations reason about these quantitatively with the geometries    (3JL8)
	[10:33] DaveKolas: The specification supports qualitative reasoning, but you would need to supply 
	your own axioms for reasoning    (3JL9)
	[10:36] KrishnaSinha: @DaveKolas: How do you see the geospatial ontology linking to time ontology? I 
	am asking this because many geologic features have changed locations through time.    (3JLA)
	[10:38] DaveKolas: @Krishna: You can use GeoSPARQL together with OWL-Time (or some other temporal 
	ontology) if you need it. Parliament has temporal indexing for OWL-Time as well.    (3JLB)
	[10:38] ArthurSmall: @DaveKolas: How, if at all, can GeoSPARQL be used to handle spatio-temporal 
	objects, such as a flight trajectory, or a moving storm front?    (3JLC)
	[10:41] DaveKolas: @ArthurSmall: There currently is not a good way in GeoSPARQL a way to describe 
	trajectories, though that might make a good reusable extension. While you could describe the points 
	along a path that something takes and attach temporal information to these points, this would get 
	very verbose quickly.    (3JLD)
	[10:36] ArthurSmall: @LeoObrst: Every database schema has an implicit ontology. Are there any tools 
	that can scan an existing database and extract the implicit ontology and suggest an OWL ontology?    (3JLE)
	[10:42] ArthurSmall: Mic trouble. ... Could you just ask the Q?    (3JLF)
	[10:42] LeoObrst: @Arthur: I'll respond a bit to your question shortly.    (3JLG)
	[10:52] LeoObrst: @Arthur: I commented on some tools such as TopBraid which can ingest XML Schemas 
	and assist in generating ontologies, but imperfectly and requires munging afterwards. Mike mentioned 
	some relational db -> semantic web standards that have emerged.    (3JLH)
	[10:59] ArthurSmall: @LeoObrst: Thank you!    (3JLI)
	[10:54] MikeDean: @ArthurSmall: upcoming Recommendations (R2RML and the Direct Mapping) from the W3C 
	RDB2RDF working group provide standard means of exposing relational data as RDF. See    (3JLJ)
	[10:58] MikeDean: @ArthurSmall: These standardize what tools like D2RQ have provided 
	for a long time. Much of the data in the Linked Data Cloud actually lives in relational databases.    (3JLK)
	[10:59] ArthurSmall: @MikeDean: Thanks!    (3JLL)
	[10:44] DaveKolas: @Arthur: what I described might work ok if you were trying to track the locations 
	that a car stopped at along a trip, but would be bad if you needed very specific detail about 
	continuous motion    (3JLM)
	[10:42] ScottHills: Is there a standard web service interface for "publishing" an ontology, for 
	consumption by applications? A simple example might involve consumption of distributed SKOS 
	ontologies by a semantic search app.    (3JLN)
	[10:44] ArthurSmall: @ScottHills: Maybe    (3JLO)
	[10:45] PeterYim: @ScottHills - you might also want to check out the Open Ontology Repository (OOR) 
	initiative - see: for various implementations    (3JLP)
	[10:45] DouglasFils: @ScottHills you might want to reference 
	too    (3JLQ)
	[10:48] ArthurSmall: Or perhaps for registering the meta-data to an existing, professionally-created 
	ontology?    (3JLR)
	[10:51] PeterYim: == KrishnaSinha & LeoObrst doing the EarthScienceOntolog Mini-series wrap-up    (3JLS)
	[10:56] AlexShkotin: Great mini-series! Thank you:-)    (3JLT)
	[11:00] LeoObrst: Thanks all!    (3JLU)

	[11:03] PeterYim: a pre-launch community brainstorm session for the OntologySummit is coming up 
	tomorrow - see: ... please come 
	(especially if you want to influence the outcome)! ... Also, mark your calendars for the 
	OntologySummit2013 Launch Event - Thursday 17-Jan-2013 2-Hr session starting 9:30am PST / 12:30pm
