Ontology Development and Application across the Earth Science Systems Lifecycle - slides    (3EO1)

This is the 2nd 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.    (3EO2)

This mini-series of events are co-organized/supported by members of the EarthCube community, Ontolog community, SOCoP community, IAOA community.    (3EO3)

This session is designed to contribute to the overall Earth Science Ontolog mini-series goal of exploring the current status and application of various semantic approaches and artifacts in order to help develop a semantically enabled cyberinfrastructure for the Earth Science Community.    (3EO4)

A key focus of this session is to continue the process started in Session 1 (see kick-off session abstract) to enable 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.    (3EO5)

Reflecting understanding achieved in earlier planning session, we believe it is important to start with an earth science perspective. We have invited speakers to discuss their needs and work reflecting actual problems facing that community. To the extent possible this discussion reflects past and current efforts on things such services, frameworks, and principles invloved in accessing and discovering data, problems bridging terminology differences insertion of semantic technology in current earth science infrastructure and the change of engaging relevant semantic technology and collaborating with the semantic community.    (3ER0)

We expect that part of the process of reaching a better understanding will include focused response from the ontological and semantic technology community to those issues. To this end we have allow time for session participants to engage in Q&A and online chat as part of open discussion. We trust that this discussion will contribute to a foundation that can be built on in the remaining sessions.    (3ER1)

	[09:38] SiriJodhaKhalsa: the diagram was a consensus diagram developed at the EarthCube PI workshop. 
	It originated at CNR    (3EUB)
	[09:39] SiriJodhaKhalsa: this diagram (slide 5) did originate w/ Interop group. the previous 
	consensus diagram originated with the brokering group    (3EUC)
	[09:47] GaryBergCross: @SiriJodhaKhalsa Thanks for the history of the graphics. I should have said 
	that I got them from INTEROP Concept group slides.    (3EUD)

	[09:47] PeterYim: @Gary - in between speakers, would you please remind those on the call, who 
	haven't logged into the chat-room, to join us there (we now have 48 people on the conference bridge, 
	but only 37 in the chat-room    (3EUF)
	[09:42] PeterYim: == RickHooper presenting his talk ...    (3EUG)
	[09:51] SiriJodhaKhalsa: why distinguish between ET from atmos energy budget and a pan measurement?    (3EUH)
	[09:51] SiriJodhaKhalsa: conceptually?    (3EUI)
	[09:55] SiriJodhaKhalsa: ScottPeckham - you've given a lot of thought to what should be in a 
	variable name, in the metadata and in an associated ontology. seems like these are getting mixed up    (3EUJ)
	[10:01] ScottPeckham: Hi SiriJodhaKhalsa. The issues with data discovery and knowledge capture are 
	different than the "semantic mediation" issues that the CSDMS Standard Names were designed to 
	address.    (3EUK)
	[10:03] ScottPeckham: The CSDMS Standard Names are described on our wiki at:    (3EUL)
	[09:56] JackRing: "When should scientist consult original source?" Always, and first. The use of 
	surrogate terms to represent context ALWAYS yields unacceptable Type 1 and Type 11 errors. Pls be 
	aware that you are being influenced by the presumption of von Neumann machines whereas modern data 
	relationship/flow machines are now available.    (3EUM)
	[09:58] SiriJodhaKhalsa: Mattia - convey across communities or simply provide brokering service?    (3EUN)
	[10:04] MattiaSantoro: @SiriJodhaKhalsa - I think the two things are not in "contrast", brokering is 
	a way of homogenizing metadata and data models across communities and information systems    (3EUO)
	[09:59] JackRing: TKU, Rick. Well said.    (3EUP)
	[10:02] RickHooper: There is a cost to documenting data for re-use that data publishers tend not to 
	want to incur. It doesn't help them personally. We need to reward the effort required for data 
	documentation.    (3EUQ)
	[10:07] FrankOlken: Rick, How are you storing (and retrieving) the various hydrological time series: 
	a relational DBMS, HDF5 files, ???    (3EUR)
	[10:07] RickHooper: relational DBMS    (3EUS)
	[10:48] FrankOlken: Rick, Out of curiosity, which relational DBMS are you using for the hydrological 
	time series?    (3EUT)
	[10:55] RickHooper: @FrankOlken: This is all on the MS platform, so we are using MS SQL Server    (3EUU)
	[10:00] PhilipMurphy: what was the URL to the HIS project? [ ... --ppy/added 
	subsequently ]    (3EUV)

	[10:11] MarshallXMa: and are links to the two papers Peter mentioned. With some 
	details of the ontology works    (3EV0)
	[10:34] GenhanChen: Rick, on your slide 6 and 7, for the hierarchical data, do you just map "leaves" 
	to variables for search? I am wondering how you deal with their parents' information (e.g. core 
	concept, property or branch).    (3EV1)
	[10:38] RickHooper: Genhan: Yes, but I should note that a leaf can be attached to more than one 
	branch, so it is not a strict hierarchy. There is no user input to the hierarchy--we control it. 
	Does that answer your question?    (3EV2)
	[10:41] GenhanChen: Rick, does it mean the parents' information will be lost?    (3EV3)
	[10:55] RickHooper: @Genhan: Not sure what you mean. The parent information is not 'lost', but it is 
	not transmitted to the user with the data or metadata return. Only the concept and the publisher's 
	variable name is transmitted to the user.    (3EV4)
	[11:03] GenhanChen: Thank you, Rick. That is what I would like to know.    (3EV5)
	[10:25] PeterYim: == MattiaSantoro presenting ...    (3EV6)
	[10:31] JackRing: What are the limitations of searching words in free text?    (3EV7)
	[10:36] SiriJodhaKhalsa: automatic mapping is the crux, and most challenging aspect of 3-party 
	mediation    (3EV8)
	[10:43] SiriJodhaKhalsa: question for Mattia: will the semantic broker be able to discover and 
	utilize vocabularies/thesauri/ontologies associated with a data source?    (3EV9)
	[10:46] SiriJodhaKhalsa: Mattia - does a new adapter have to be created for each new semantic 
	resource?    (3EVA)
	[10:54] MattiaSantoro: @SiriJodhaKhalsa - A new adapter has to be created for each communication 
	protocol and/or data/metadata model    (3EVB)
	[10:46] JackRing: Mattia. Will you be measuring False Positives and False Negatives?    (3EVC)
	[10:56] MattiaSantoro: @JackRing - yes false positive is one thing we will measure to improve the 
	association strategy    (3EVD)
	[10:59] MattiaSantoro: @JackRing - the main issue with free text is in multidisciplinary contexts, 
	where the same word might have different meanings depending on the discipline (or sometimes even 
	depending on the language)    (3EVE)
	[11:05] JackRing: Mattia, TKU. How will you measure false negatives, i.e., things that existed but 
	not found?    (3EVF)
	[11:07] JackRing: Mattia, Cannot the ambiguity of what a word signifies be resolved by assessing 
	context? Are you seeking to avoid combinatorial explosions in the computations?    (3EVG)
	[10:47] PeterYim: == NaicongLi presenting ...    (3EVH)
	[11:03] FrankChum: Great presentation, NaicongLi. Sorry I have to jump off to another meeting.    (3EVI)
	[11:09] PeterYim: == open Q&A and discussion ... please click on "hand" button (lower right) to 
	notify the chair, and when recognized, announce yourself and make sure you can be heard before 
	speaking    (3EVJ)
	[11:09] anonymous1 morphed into FrankDAgnese    (3EVK)
	[11:14] BobbinTeegarden: @all speakers What are you using for visualization, and is there any direct 
	interaction with the visualization itself?    (3EVL)
	[11:14] RickHooper: Startree viewer is what we are using, but there are problems with that.    (3EVM)
	[11:14] KrzysztofJanowicz: [ref. verbal question from SiriJodhaKhalsa] Are you asking about ontology 
	alignment?    (3EVN)
	[11:17] GaryBergCross: >[Krzyszto] Are you asking about ontology alignment? - I don't think so.    (3EVO)
	[11:16] SiriJodhaKhalsa: thanks    (3EVP)
	[11:19] KrzysztofJanowicz: @SiriJodhaKhalsa: With respect to Spatial Data infrastructures there is 
	work on the automatic meditation of sensor metadata and observation data to ease the registration at 
	Sensor Observation Services. I would consider this similar to a brokering with a reduced amount of 
	human interaction.    (3EVQ)
	[11:23] anonymous morphed into DaliaVaranka    (3EVR)
	[11:23] JackRing: Whereas each of us has a 25.000 to 75,000 word vocabulary many projects/companies 
	run just fine with 2500 word vocabularies. Local ontologies are necessary. However Log(variety) = 
	K*Log(extent) so as we seek interoperability among ever-larger communities then the ability to 
	interoperate local ontologies becomes valuable.    (3EVS)
	[11:29] MarcioFaerman: @JackRing, could you please explain what you mean by K, variety and extent in 
	your previous statement? Thanks!    (3EVT)
	[11:33] JackRing: @Marcio. As a system gets larger in scope (extent) it inexorably gets increasingly 
	heterogeneous (variety of elements and relationships). In complex systems research we often not that 
	the relation is log(variety) = 0.7*log(extent) however many systems are messy so we even see that 
	variety increases in a static system.    (3EVU)
	[11:34] MarcioFaerman: Tks @JackRing!    (3EVV)
        [11:25] KrzysztofJanowicz: [ref. RickHooper's remark that "some taxonomy is important, but it is not 
        important to achieve a consensus on the taxonomy" (as different people use different logics to 
        organize their terms, and their taxonomies will come out different)] I could not agree more.    (3EWK)
	[11:28] KrzysztofJanowicz: I agree that while terminologies are important, common agreement is not 
	always important and difficult to archive.    (3EVX)
        [11:28] Gary Berg-Cross: Krzysztof comment above was in the context of my question on value of 
        taxonomies and modular ontologies.    (3EVY)
	[11:29] GaryBergCross: I want mention the Dayton Vocamp this Sept 15-17 which may be of interest to 
	some session attendees. Kno.e.sis Center at the Department of Computer Science and Engineering of 
	Wright State University in Dayton, OH focus on the observation-driven engineering of geo-ontologies 
	by developing small, self-contained, and reusable geo-ontology design patterns that can be used to 
	annotate geo-data    (3EVZ)
	[11:32] PeterYim: == GaryBergCross wrapping up the session ...    (3EW0)
	[11:32] PeterYim: join us again for session-3 of this mini-series on Oct-11 ... please mark your 
	calendars    (3EW1)
	[11:32] PhilipMurphy: Could we have such a Use Case <> Ontology development Ontolog session in the 
	future?    (3EW2)
	[11:33] GaryBergCross: @PhilipMurphy - I'm all for it    (3EW3)
	[11:33] MarcioFaerman: Ditto, @PhilipMurphy    (3EW4)
	[11:34] Scott Hills: Re: Future Use Case <> Ontology session - I agree.    (3EW5)
	[11:33] PeterYim: [added subsequently] @PhilipMurphy & All - Indeed! Also, the 5th session of this 
	mini-series slated for Dec-6 entitled: "Tutorial" to be chaired by NancyWiegand and MikeDean, could 
	well be part of what you are looking for. Come join us then, and let's try to refine on what kind of 
	session(s) would be most useful.    (3EW6)
