Abstract     (1K)

Value Proposition of Ontology and Semantic Technology for the Earth Science Community - slides     (1K1)

This is the kick-off 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.     (1K2)

This mini-series of events are co-organized/supported by members of the Earth Cube community, Ontolog community, SOCoP community, IAOA community.     (1K3)

The Earth Science Ontolog mini-series is designed to explore the current status and application of multi-level ontologies towards developing a semantically enabled cyberinfrastructure for the Earth Science Community. In addition, one key mission of the mini-series is to bring together members of both communities (Earth Science and ontology/semantics) into a meaningful dialog. We anticipate that the sharing of requirements and use cases, geo-science problems and issues, ontological engineering architectures and approaches, and prospective tools, will enable collaborative understanding of the challenges and potential value in the application of ontology and semantics in Earth Science.     (1K4)

At our planning session, the organizing committee thought it very important that the Geo-Science community and the Ontology / Semantics community come together and begin to understand each other better. So at this first session of the mini-series, we will start with some geo-scientists discussing needs, use cases, etc., from their perspective, i.e., what are the problems facing the Geo-Science community, e.g., data access and discovery issues, impeding terminology differences, changing collaboration models, etc. Then some ontologists / semantic technologists could respond to those issues and offer what they see as the value proposition to Geo-Science. This kind of discussion, joined in by the session participants in the ensuing Q&A and open discussion, augmented by our in-session in chat, could lay the foundation for the remaining sessions, give us all some initial common understanding.     (1K5)

Briefings     (1K7)

  • Professor KrishnaSinha (Virginia Tech) - "How Can Semantics Change Data Practices of the Earth Cube Geoscience Community?" - slides     (1K7A)
    • Abstract: ... It is well recognized that solutions to new scientific challenges are rooted in use/reuse of data and tools. However, current data and tool sharing practices face many barriers, and is especially dominant in the world of individual researchers (long tail of science community) whose observational data are required to understand how natural systems change over time through physical, chemical, and biological processes. The most common reasons cited by individual researchers are related to lack of time, future publishing opportunities, ownership of data, concerns related to misuse of data, credit for professional advancement, lack of institutional support,and opportunities for commercial applications. These cultural challenges can be mostly resolved through use of semantics by: (1) developing technologies that enable individual researchers to share data quickly and easily while retaining ownership, (2) creating a system for providing credit through data citation index (measure of reuse), and controlled lineage through multiple data cycles, and (3) demonstrate through semantically resolved real world use cases, that timely sharing of data can lead to efficiencies in discovering new knowledge.     (1K7A1)
  • Professor KrzysztofJanowicz (UC Santa Barbara) - "The Value Proposition of Semantic Technologies and Ontologies for the Earth Sciences" - slides     (1K7B)
    • Abstract: ... Semantic technologies and ontologies are proposed as key building blocks for next-generation scientific infrastructures and workflow systems. However, their added value often remains hidden from the user and their potential is often not exploited beyond improving keyword search. This talk outlines which role semantic technologies and ontologies can play within the earth sciences and how they can support scientists in publishing, discovering, and integrating data.     (1K7B1)
  • Dr. DaliaVaranka (USGS) - "Rethinking the Meaning of Data for Integrated Science Problem Solving" - slides     (1K7C)
    • Abstract: ... The implementation of valuable legacy data using semantic technologies provides the opportunity to reexamine the way the data were historically modelled and interpreted compared to the way they can be used to meet updated objectives. The discovery of contradictions or inconsistencies in the data, as well as strengths and enduring uses, and designing new solutions takes time, but can improve scientific inquiry by sharpening the focus on the way that the data interacts within an information network and responds to user needs. Semantic technology provides ways to expand the expression of data semantics to stress the desired aspects needed for science analysis.     (1K7C1)
  • Professor PascalHitzler (Wright State U) - "On the uptake of Semantic Web Technologies" - slides     (1K7D)
    • Abstract: ... In this talk I'll present a birds eyes' perspective on the uptake of Semantic Web Technologies in application areas. I'll dare to make some projections, and will briefly line out some important considerations for aligning Earth Science data management and use with the state of the art in Semantic Web Technologies.     (1K7D1)
  • Mr. MikeDean (Raytheon-BBN) - "Semantic Web for Earth Science" - slides     (1K7E)
    • Abstract: ... Semantic Web technologies (including the synergistic combination of ontologies and linked data) appear to be widely applicable to large scale earth science data management and applications. We'll briefly discuss ontologies, linked data, and several particularly relevant emerging technologies: GeoSPARQL, the RDF Data Cube Vocabulary, RDB to RDF, and provenance.     (1K7E1)

[09:37] Peter P. Yim: == Leo Obrst started the session with the introductory slides     (1M2AAJ)

[09:40] Todd Schneider: Leo, what does 'multi-level' ontology mean?     (1M2AAK)

[09:47] Leo Obrst: "Multi-level" can mean 2 things: 1) the typical foundational, midlevel/super     (1M2AAL)

domain, and domain levels of ontological architecture, but also 2) multiple levels of granularity     (1M2AAM)

and contexts/perspectives in specific domains such as Earth Science.     (1M2AAN)

[09:51] Peter P. Yim: @Leo - please prompt those on the call to log into the chat-room again (we have 45     (1M2AAO)

people on the call now)     (1M2AAP)

[09:43] Peter P. Yim: == Krishna Sinha presenting ...     (1M2AAQ)

[09:56] Scott Hills: Regarding discovery of data: This does not just apply to that held by     (1M2AAR)

individuals, but to that maintained in "Data Centers" as well. How many Data Centers might contain     (1M2AAS)

data of interest, and how many of those do you know about, and know how to use (each often has a different UI)?     (1M2AAT)

[10:14] Krishna Sinha: Hi Scott, The data centers are very visible and their data content is well     (1M2AAU)

known; an ontology framework that can map the data held in different centers would be welcome     (1M2AAV)

[10:15] Pascal Hitzler: @Krishna - what do you mean with "framework" here?     (1M2AAW)

[10:18] Krishna Sinha: @Pascal- an ontology based infrastructure that points to the data content of data centers     (1M2AAX)

[10:15] Anne Thessen: This is true for many data centers, but there are some, such as Dryad that     (1M2AAY)

takes files with little to no guidance as to structure or content     (1M2AAZ)

[10:16] GenhanChen: To Krishna: could you provide an example to explain the ontology framework on your slide #11?     (1M2AAAA)

[10:19] Scott Hills: Krishna, we may have different definitions for visibility. They may be     (1M2AAAB)

accessible (your sense of "visible?"), but I question how many people know *where* to access them.     (1M2AAAC)

For example, if I ask for the data centers that contain geochemical data, or seismic data, or well     (1M2AAAD)

cores (take your pick), how many people could offer a comprehensive list?     (1M2AAAE)

[10:26] Krishna Sinha: @ Scott-- a high level ontology that can capture the data types held at     (1M2AAAF)

Centers would enable a user to find which centers hold what types of data     (1M2AAAG)

[10:49] Doug Foxvog: Scott Hills asks above "how many people could offer a comprehensive list [of data     (1M2AAAH)

centers that contain various types of geochemical data]". This seems to me to actually be a call for     (1M2AAAI)

a knowledge base of data centers containing information about what types of data are covered in the     (1M2AAAJ)

various data centers. With linked data, such a knowledge base need not be centrally located, merely     (1M2AAAK)

a vocabulary for making the statements needs to be defined, each data base could specify what types     (1M2AAAL)

of data it covers, and the linked data needs to be made widely available.     (1M2AAAM)

[10:41] Scott Hills: Krishna, our thinking is starting to converge. The point I was working toward: I     (1M2AAAN)

believe a good argument can be made for the need for ontologies that enable discovery of data across     (1M2AAAO)

the landscape of proliferating Data Centers. I suspect the same ontologies would help enable     (1M2AAAP)

discovery of data published by individuals. That said, I suspect the "level" of such ontologies need     (1M2AAAQ)

to go beyond data type, or their utility will be very limited.     (1M2AAAR)

[10:44] Krzysztof Janowicz: Scott, yes ontologies should always be 'more' than just data models     (1M2AAAS)

[10:47] Krishna Sinha: @Scott--I agree, and I also think most users would be comfortable with high to medium level granularity     (1M2AAAT)

[10:19] Amit Deokar: @Krishna - We notice a lot of emphasis on managing data. What are your views on     (1M2AAAU)

how important it is to manage associated computational models, share them, annotate them, and so     (1M2AAAV)

forth so that they are accessible like data, avoiding problems of reinventing the wheel?     (1M2AAAW)

[10:22] Krishna Sinha: @ Amit- i support an ontology framework that organizes services that would     (1M2AAAX)

include existing models and other computational tools..its the service ontology on slide 11     (1M2AAAY)

[10:41] John Graybeal: @Krishna: Re your endorsement of data citation: Why should this community     (1M2AAAZ)

particularly endorse data citation, more than it should endorse all the data practices that benefit     (1M2AAAAA)

from ontologies: description, provenance, versioning, unique identification, ...? All seem noble causes.     (1M2AAAAB)

[10:58] Leo Obrst: @Krishna: I think one very important issue you raised is the incentive for     (1M2AAAAC)

individuals (and organizations) for sharing data: in the research community, what is the incentive     (1M2AAAAD)

for a researcher to expose his/her data and its meaning? What supports scholarly acknowledgment of     (1M2AAAAE)

the contribution?     (1M2AAAAF)

[11:02] Krishna Sinha: @Leo--There are two ways to expose data..regular publications for which there     (1M2AAAAG)

is a citation index ( often used for promotions etc) ..the critical issue is what incentives we can     (1M2AAAAH)

support to have people share data that is not formally citation index is one way to go     (1M2AAAAI)

[09:57] anonymous1 morphed into SiriJodhaKhalsa     (1M2AAAAJ)

[09:58] anonymous morphed into Pavithra Kenjige     (1M2AAAAK)

[09:59] anonymous1 morphed into DeborahMcGuinness     (1M2AAAAL)

[10:02] anonymous morphed into Krishna Sinha     (1M2AAAAM)

[10:00] Pavithra Kenjige: Did he say that we have such a semantic infrastructure already available??     (1M2AAAAO)

[10:01] Chuck Ward: Have you also considered community expectations such as data archiving     (1M2AAAAP)

requirements with journal articles? e.g. evolutionary biology     (1M2AAAAQ)

[10:09] SiriJodhaKhalsa: what is the advantage of creating or using an ontology for encoding     (1M2AAAAR)

provenance/quality/appropriateness-of-use information beyond creating metadata according to a     (1M2AAAAS)

well-defined standards like ISO 191**?     (1M2AAAAT)

[10:37] John Graybeal: To Siria Jodha (Hi!): The advantages of using ontologies for encoding any     (1M2AAAAU)

content, *including* provenance/quality/appropriateness-of-use information: (1) Readers of the     (1M2AAAAV)

metadata know exactly what you mean ('exactly', relatively speaking), (2) there is better     (1M2AAAAW)

mapping/understanding across communities for these concepts. (While I appreciate ISO 191** provides     (1M2AAAAX)

vocabularies, I often find them underdefined, incomplete, and locally inconsistent. And often ISO     (1M2AAAAY)

191** doesn't provide a vocabulary, so the content is wide open.)     (1M2AAAAZ)

[10:09] Peter P. Yim (added subsequently): @SiriJodhaKhalsa - you might want to take a look at the two     (1M2AAAAAA)

Ontology Summit communiques - Ontology for Big Systems:     (1M2AAAAAB)

benefits were enumerated by the community     (1M2AAAAAE)

[10:23] Leo Obrst: @Krzysztof: you cited some research concerning the last bullet on translation     (1M2AAAAAF)

between conceptual models on slide 5. Can you provide that reference?     (1M2AAAAAG)

[10:27] Krzysztof Janowicz: Yes Leo, for instance the work of Mark Gahegan. This paper may be a good     (1M2AAAAAH)

starting point and overview: A Semantic Web Map Mediation Service: Interactive Redesign and Sharing     (1M2AAAAAI)

of Map Legends by Mark Gahegan, Will Smart, Sina Masoud-Ansari, and Brandon Whitehead.     (1M2AAAAAJ)

[10:52] Peter P. Yim: whoever said, "Krzysztof, fully agree with your view. Understanding formal     (1M2AAAAAK)

semantic and reusing well fundamented ontologies. " ... please note that the space to type your     (1M2AAAAAL)

message is next to the "send" button (at the bottom) and not the box next to the "hand" button     (1M2AAAAAM)

[10:15] anonymous morphed into Doug Foxvog     (1M2AAAAAN)

[10:15] anonymous morphed into ScottPeckham     (1M2AAAAAO)

[10:30] Krzysztof Janowicz: "Did he say that we have such a semantic infrastructure already     (1M2AAAAAR)

available??" --> I would argue so     (1M2AAAAAS)

[10:52] Scott Hills: Pascal, would you agree that whether an ontology is high-quality depends on how     (1M2AAAAAT)

well it satisfies the needs for which it was engineered?     (1M2AAAAAU)

[10:55] Pascal Hitzler: @Scott - this looks reasonable, however I would think that more can be said     (1M2AAAAAV)

about the "quality" issue. In fact, there is quite a bit of work on "Evaluation of Ontologies", and     (1M2AAAAAW)

there is also a established workshop series about this topic.     (1M2AAAAAX)

[10:57] Bobbin Teegarden: @Pascal URL for the workshop?     (1M2AAAAAY)

[10:58] Pascal Hitzler: I suggest to start with DennyVrandecic's PhD thesis:     (1M2AAAAAAA)

[10:48] Peter P. Yim: == Mike Dean presenting ...     (1M2AAAAAAB)

[10:51] anonymous morphed into MarshallXMa     (1M2AAAAAAC)

[11:18] Leo Obrst: @Mike: do you have a url for the LOD Framework initiative?     (1M2AAAAAAD)

[11:02] Peter P. Yim: == open discussion commences ...     (1M2AAAAAAE)

[11:05] Pascal Hitzler: Leo / Krishna: The Semantic Web journal, for example, recently established     (1M2AAAAAAG)

Linked Dataset Descriptions as regular paper type. The purpose of this introduction is to generate     (1M2AAAAAAH)

academic incentive for the production of high-quality Linked Datasets.     (1M2AAAAAAI)

[11:07] MarshallXMa: @Pascal: Another journal (Geoscience Data Journal) with similar ideas:     (1M2AAAAAAJ)

[11:03] MarshallXMa: @LeoObrst: Such as, a stable repository to upload and describe (with a metadata     (1M2AAAAAAL)

form) the dataset, and easy way to assign a DOI for it.     (1M2AAAAAAM)

[11:11] Todd Schneider: John, part of the needed infrastructure is the Open Ontology Repository.     (1M2AAAAAAN)

[11:12] John Graybeal: Yes (the question was, "What has to happen on the ground for these advantages     (1M2AAAAAAO)

to be obtained?" With particular attention to the practical realities of the practicing data     (1M2AAAAAAP)

[11:13] John Graybeal: @Todd: As provider of an OOR equivalent (MMI's ORR), I want to go farther.     (1M2AAAAAAR)

Let's assume there's a perfect repository in existence. And even, really good vocabularies from     (1M2AAAAAAS)

communities. How do they integrate this into their developed data systems?     (1M2AAAAAAT)

[11:14] Todd Schneider: John, education. It would appear that many people working in the area of     (1M2AAAAAAU)

semantic technologies' don't know enough. Dalia addressed this.     (1M2AAAAAAV)

[11:16] Krzysztof Janowicz: John, IMHO it needs a earth science specific tutorial and a set of     (1M2AAAAAAW)

reusable building blocks     (1M2AAAAAAX)

[11:14] Scott Hills: Pascal, thanks for the URL. I'll look through the material (up through 2007?).     (1M2AAAAAAY)

Any chance I'll find suggestions to answers like, what applications are best served using SKOS vs.     (1M2AAAAAAZ)

OWL DL with domain-specific properties?     (1M2AAAAAAAA)

[11:18] Pascal Hitzler: @Scott - I would guess that answers to such specific questions can probably     (1M2AAAAAAAB)

not be found easily. "Best practices" in applying semantic technologies are not (yet) written up in     (1M2AAAAAAAC)

any concise form, afaik. Note that it is only two years or so that we got textbooks which cover the     (1M2AAAAAAAD)

bare basics of the discipline. Currently, I guess the best approach to get such questions answered     (1M2AAAAAAAE)

is to consult a specialist.     (1M2AAAAAAAF)

[11:15] Marcio Faerman: My question referred on how to justify and support, throughout the community,     (1M2AAAAAAAG)

@KrzysztofJanowicz "Final Thought" slide - "... It seems that we hope to arrive at semantic     (1M2AAAAAAAH)

interoperability by standardization instead of investing into research on alignment and semantic     (1M2AAAAAAAI)

translation to reduced incompatibility. This may turn out to be a fundamental misconception. I     (1M2AAAAAAAJ)

believe that standardization is the more difficult of both approaches..."     (1M2AAAAAAAK)

[11:18] Marcio Faerman: Then I followed up with the question about conciliating multi-disciplinary     (1M2AAAAAAAL)

research and knowledge discoverability through semantic translation.     (1M2AAAAAAAM)

[11:16] Mike Bennett: Something we are finding is the distinction between one ontology for one     (1M2AAAAAAAN)

application, versus overall domain ontology (standard) which is use-case neutral. Both are vital.     (1M2AAAAAAAO)

And different.     (1M2AAAAAAAP)

[11:19] Krzysztof Janowicz: Mike Bennett, yes -- I am not arguing against higher level ontologies. It     (1M2AAAAAAAQ)

[11:19] Mike Bennett: @Krzystof agreed. Work to be done on the heuristics for extracting a relevant     (1M2AAAAAAAS)

sub-set of domain ontology for a given use case.     (1M2AAAAAAAT)

[11:22] John Graybeal: @Mike: In addition to single ontology vs overarching ontology, there are     (1M2AAAAAAAU)

typically multiple authoritative (sic) vocabularies within each domain, and maybe one or two     (1M2AAAAAAAV)

ontologies as well. Making integrative use of that information is, for now, impossible without a lot     (1M2AAAAAAAW)

of human investment.     (1M2AAAAAAAX)

[11:24] Mike Bennett: @John very much so. Needs to be done across industries. One chance to get it     (1M2AAAAAAAY)

right I think.     (1M2AAAAAAAZ)

[11:25] Krzysztof Janowicz: IMHO, this makes GeoSPARQL so strong     (1M2AAAAAAAAA)

[11:27] Scott Hills: Pascal, thanks for that info (13:18). Good to know, since I haven't been able to     (1M2AAAAAAAAB)

find such material to date.     (1M2AAAAAAAAC)

[11:29] Joanne Luciano: Thanks to the organizers and presenters!     (1M2AAAAAAAAD)
