Updated Rich's Two Species and additional thoughts and example on how to handle alternative conceptualizations
by Peter DeVries 10 May '11

10 May '11

I have added some additional information the the TaxonConcept KB for Rich's two fish About: Centropyge fisheri se:q72fd Orange Angelfish http://lsd.taxonconcept.org/describe/?url=http%3A%2F%2Flod.taxonconcept.org… bit.ly http://bit.ly/j1c7NF About: Centropyge flavicauda se:Mj6j4 Whitetail Angelfish http://lsd.taxonconcept.org/describe/?url=http%3A%2F%2Flod.taxonconcept.org… bit.ly http://bit.ly/mwQIyh * Assuming the photo's are correct, these examples still need links to representative specimens and other related data. This was done by creating this file and adding it to the triplestore http://assets.taxonconcept.org/fb/index.rdf Data about the image http://lsd.taxonconcept.org/describe/?url=http%3A%2F%2Fassets.taxonconcept.… bit.ly http://bit.ly/jjmnsd If I understand Rich correctly all these images would be instances of the concept *Centropyge fisheri sensu lato* * * *That would need it own URI and could be related by something like this:* * * <http://lod.taxonconcept.org/ses/q72fd#Species> txn:hasWiderAlternativeConceptualization < http://lod.alternativeconcepts.org/ses/10252#Species> <http://lod.taxonconcept.org/ses/Mj6j4#Species> txn:hasWiderAlternativeConceptualization < http://lod.alternativeconcepts.org/ses/10252#Species> and <http://lod.alternativeconcepts.org/ses/10252#Species > txn:hasNarrowerTXNConceptualization < http://lod.taxonconcept.org/ses/q72fd#Species> <http://lod.alternativeconcepts.org/ses/10252#Species > txn:hasNarrowerTXNConceptualization < http://lod.taxonconcept.org/ses/Mj6j4#Species> I think it is cleaner to have the overlapping concepts separated into a different namespace. This implies that the set of alternativeconcepts don't overlap with each other. So what I am proposing allows for alternative concepts. It does not appear that The Plant List has alternative concepts, each species has a current name and the set represents their form of a set of non overlapping concepts. Why isn't this controversial? Note also that things like The Plant List don't do much to improve the lot of those who document and describe species. You cite the authors of The Plant List. This is in contrast to TaxonConcept where you site the species editors and the original author is linked via their DBpedia description. (In many cases these will need to be added to Wikipedia, about 6,000 already) Respectfully, - Pete ------------------------------------------------------------------------------------ Pete DeVries Department of Entomology University of Wisconsin - Madison 445 Russell Laboratories 1630 Linden Drive Madison, WI 53706 Email: pdevries(a)wisc.edu TaxonConcept <http://www.taxonconcept.org/> & GeoSpecies<http://about.geospecies.org/> Knowledge Bases A Semantic Web, Linked Open Data <http://linkeddata.org/> Project --------------------------------------------------------------------------------------

Hi Pete, > Hi Steve, > > I may have overloaded the term specimen to make the explanation easier to follow. > A specimen could be an individual or it could be part of an individual. > To some extent you need to think about how these models will be used. > If you subscribe to the model that a species is whatever a taxonomists says it is then it is difficult to make statements like. > X% of the world's species will be extinct by 2050. > If you mean a species as defined by the concept documented at this URI which is supported by these specimens, images, and DNA then you are on firmer ground. I would have stopped here! If someone wants to point to a series of objects to indicate his own concept of a "species", then that's ok. That's a convention we can work with. Everything else you talk about below seem to be a confused mashup of "species" as a taxon and "species" as ranks. > Species in the natural world do a pretty good job recognizing those individuals that are appropriate mates. In other words members of their own species. Really? Maybe in animals but everywhere else I don't think so! And what about asexual organisms? I guess they do not deserve the status of "species". So, the biological species concept you are referring to can't be universally applied = not a good concept to use for ALL organisms, right? > Are we modeling species or variations in human conceptualizations of species? Is there anything else out there besides the human conceptualization of species? Do we have an absolute concept of what a species represent? Last time I checked we have been arguing about this for the past century and more. Species defined by the 25+ species concepts out there can't possibly be real. They are defined by human conceptualization = artificial. The only think we can clearly try to discern are clades and often those clades may correspond with someone's concept of a species. In other words, you can take the rank of species and point it at a node that define a taxon. Or you can take the rank of species and point it to an assemblage of lineages, regardless if that assemblage represents a monophyletic group or not. Traditionally recognized species are most likely polyphyletic anyways. > I stick with this. Assuming you don't have a hybrid individual. That individual is one species. The fact that human may disagree on what species it is a human issue. What do you really mean by individuals? Are species created by the gods and we just can't figure out what they meant? Human issue? We, humans came up with this impossible to define concept. Individuals are just that: individuals. The individuals = species hypothesis has been argued in the literature and is not an accepted notion by far (note: I am not saying I agree or disagree, this is just another non-absolute concept). But maybe you don't mean it that way. > Again, Are we modeling species or variations in human conceptualizations of species? Your statement is recursive. You have an idea of species that is above all of the other variations on the theme. I don't understand what you mean and that's why I think there is a confusion between the usage of "species" as a taxon and "species" as an arbitrary rank. > Which of these is of primary importance to decision makers and non-taxonomist biologists? > Part of the problem with various publications relating to ontologies and taxonomy is that their species models entail a specific phylogenetic hypothesis. Even in the lack of a phylogenetic framework, every species is a hypothesis. When we lump and split we generate hypotheses. A new name points to a new hypothesis. Adding a new genus to a family or a new species to a genus refines and modifies the original hypothesis. > In the real world taxa are not as clean as some would like to make them out to be. In fact, the only way we can discover a little more clarity is through phylogenies. When it comes to low level taxa, population studies help a lot too. > Each individual is a unique combination of thousands of separate gene lineages which often do not follow clean monophyletic paths. But as you stated above you equate individuals with species. if that's correct, then you admit that individuals can be polyphyletic, and as such do we really care about polyphyletic entities? As such you admit that species as you define them are artificial. > I would argue that most of those who work with species related data see them as useful typological constructs which in general follow the biological species model. I actually don't and I can name many others who don't. The rank of species may be useful to many as communication tool but the way it is applied vary a lot. The biological species concept is not widely accept and certainly not followed by the vast majority as you indicate. The only think we can really achieve from an informatics standpoint is to reconcile objects (specimens, images, sequences, descriptions, etc.etc.) with the many names that may have been associated with those and leave the rest (philosophical masturbation) to the users. Reconciling names with concepts, given the nature of the concepts and the idiosyncratic way that names have been historically used, is a Quixoterian challenge.

I have reached the conclusion that a specimen CAN be an individual if one chooses to type a particular "thing" as both a specimen and and an Individual but I'm not comfortable with saying that they are owl:sameAs . It is my opinion, and I think one that was supported to some extent in the discussion of last Oct/Nov that when we "identify" some kind of evidence like a a branch cut from a tree we are really making a statement about what taxon we think the tree represents, not the branch per se. This is an important distinction, because if we are identifying the tree, then any branch that is dcterms:partOf the tree shares that identification. This may seem like an esoteric point, but it is one that has a fairly significant bearing on how one chooses to construct a model. I will stop there because I don't want to re-plough the same ground again.

It was my understanding (again from the extensive conversation about this in Oct/Nov) that the creation of multiple Identifications were "preference agnostic". Each Identification represented an expressed opinion about the concept/TNU that the determiner asserted that the individual represented. They were not flagged as "right" or "wrong". In fact, it is possible that there could be several Identifications by different determiners that asserted the same concept/TNU, indicating that the determiners agreed with each other. > >> >> Assuming that there was only one individual organism identified there is really one one species (or hybrid). > Aaaaaaaaaaaaaah!

This email relates to the actual suggestion that you made in the email, that is to use the URIs of the form like: "http://lod.taxonconcept.org/ses/mCcSp#Occurrence". In the RDF that defines what this URI means, the URI is described as "A lightweight tag that can be used to label occurrences of this species". What I'm not sure about is what exactly one is supposed to do with it. From the example that I was talking about in the previous email (http://ocs.taxonconcept.org/ocs/f522444a-2dd9-400e-be59-47213ef38cb9.rdf), this "tag" is the object of the predicate txn:occurrenceHasSpeciesOccurrenceTag . So I guess that it is another way that one could query Occurrence records to find out which ones are Occurrences of the species having the identifier "ICmLC" (Boloria selene). But I'm not sure what the advantage of that is. The RDF for the Occurrence already tells me that the Occurrence has the txn:occurrenceHasSpeciesConcept property with object URI http://lod.taxonconcept.org/ses/ICmLC#Species . I can resolve that URI and "find out" that the "species concept" (sensu DeVries) is Boloria selene . But if I used the "lightweight tag" I'd also have to resolve its URI to find out about it and the RDF for the tag directs me to the http://lod.taxonconcept.org/ses/ICmLC#Species URI anyway via the dcterms:isPartOf property of the tag. I guess the point is that if one wants to "find out" about the Occurrence, it takes two steps to get to the species concept description if I use the tag (first through txn:occurrenceHasSpeciesOccurrenceTag, then through dcterms:isPartOf) which is no advantage over just getting there in one step (via txn:occurrenceHasSpeciesConcept). If the only point is to have something to put in as a search term, then why not just make the txn:occurrenceHasSpeciesOccurrenceTag a data property with the literal object the string "ICmLC"? >> >> I suppose that one could say that an advantage of the "lightweight tag" approach would be that one is indicating that the particular Occurrence is an instance of a class that consists of all Occurrences of the species Bororia selene. That seems to be what the intention is. But this seems to be a case of creating many subclasses rather than having a general class and assigning it properties that help one to understand the nature of the instance of that class. It requires the creation of a class for every species on the planet. Instead of there being a relatively small number of classes that includes the basic kinds of resources (Occurrence, individual, Identification, taxon concept) there is a class for occurrences of every kind of taxon concept. Actually, there are several classes for every instance of taxon concept, because you are recommending that the "lightweight tag" approach be used for other types of things as well, such as individuals and (in your suggestion below, populations). There isn't anything intrinsically "wrong" with this approach, but with my bias toward preferring "well known" types/classes it just seems like a lot to expect consuming applications to "understand" what amounts to potentially millions of classes that this method would introduce. >> >> I also don't quite understand what a txn:SpeciesOccurrenceTag is exactly. In the RDF that defines the txn:SpeciesOccurrenceTag instance for Bororia selene (http://lod.taxonconcept.org/ses/ICmLC#Occurrence) the dcterms:description says that it "allow species occurrences to be modeled as instances of SpeciesOccurrenceTag". But that doesn't seem to be what is actually occurring. When the Occurrence instance http://ocs.taxonconcept.org/ocs/f522444a-2dd9-400e-be59-47213ef38cb9#Occurr… is described, it is not typed as the lightweight tag (which IS a txn:SpeciesOccurrenceTag because of the implicit typing caused by the XML container element name). The lightweight tag URI is the object of the txn:occurrenceHasSpeciesOccurrenceTag property, but that doesn't make the Occurrence an instance of SpeciesOcurrenceTag as would be the case (I think) if the lightweight tag URI were the object of a rdf:type property. Anyway, I'm confused about this. >> >> The other issue that I would raise with this approach is that it brings up the same issue that I raised in the other email that I wrote. It essentially puts a burden of anticipating the results of a query onto the metadata provider. If one follows the model of allowing multiple Identifications for an organism, then it is possible that someone somewhere else might apply their own Identification instance to the individual represented in the Occurrence. As was the case in my earlier example, for txn:occurrenceHasSpeciesOccurrenceTag to be useful as a thing to be queried, the metadata provider would need to somehow know that this additional Identification had been made, and then create another txn:occurrenceHasSpeciesOccurrenceTag property for the Occurrence instance. This seems to somewhat at odds with the benefit that the Linked Data world has in allowing resources to be created by people all over the cloud and then linked rather than expecting a centralized authority to do everything. >> >> Anyway, maybe you can explain what is going on so that I can understand it better and maybe explain why this approach is better than just creating a few classes and describing their instances by descriptive properties. >> >> Steve >> >> >> Peter DeVries wrote: >>> >>> I am still somewhat puzzled why TDWG seems so opposed to adopting anything that comes from outside a small click? >>> >>> I was thinking that it would be best to create a separate class that can be used for populations of a species. >>> >>> This would require adding an additional tag to the TaxonConcept Species Concept Model, which currently includes several tags like entities >>> >>> http://lod.taxonconcept.org/ses/mCcSp#Species <- The Species Concept for the Cougar >>> >>> See http://lod.taxonconcept.org/ses/v6n7p.html HTML >>> http://lod.taxonconcept.org/ses/v6n7p.rdf RDF >>> http://lsd.taxonconcept.org/describe/?url=http%3A%2F%2Flod.taxonconcept.org… Knowledge Base View (http://bit.ly bit.ly/gMFqR1 >>> >>> The model mints URI's for the following related entities.

If you need something for referring to a population, then it is probably best to do it as a related class
by Peter DeVries 10 May '11

10 May '11

I am still somewhat puzzled why TDWG seems so opposed to adopting anything that comes from outside a small click? I was thinking that it would be best to create a separate class that can be used for populations of a species. This would require adding an additional tag to the TaxonConcept Species Concept Model, which currently includes several tags like entities http://lod.taxonconcept.org/ses/mCcSp#Species <- The Species Concept for the Cougar See http://lod.taxonconcept.org/ses/v6n7p.html HTML http://lod.taxonconcept.org/ses/v6n7p.rdf RDF http://lsd.taxonconcept.org/describe/?url=http%3A%2F%2Flod.taxonconcept.org… Base View (http://bit.ly bit.ly/gMFqR1 The model mints URI's for the following related entities.

Updated TDWG BioBlitz SPARQL Example
by Peter DeVries 06 May '11

06 May '11

Thanks for the Clarification
by Peter DeVries 04 May '11

04 May '11

Reading the tea leaves it seems that the TDWG Illuminati determined that * indeed* the current DarwinCore was not good for the semantic web and formed a group to create one. This explains why my work initially characterized as a small data set about mosquitoes in the original KOS draft and is now not mentioned at all. Thank your for clarifying how TDWG operates. - Pete ------------------------------------------------------------------------------------ Pete DeVries Department of Entomology University of Wisconsin - Madison 445 Russell Laboratories 1630 Linden Drive Madison, WI 53706 Email: pdevries(a)wisc.edu TaxonConcept <http://www.taxonconcept.org/> & GeoSpecies<http://about.geospecies.org/> Knowledge Bases A Semantic Web, Linked Open Data <http://linkeddata.org/> Project --------------------------------------------------------------------------------------

DwC for the semantic web
by Steve Baskauf 04 May '11

04 May '11

Dear colleagues, With the exciting development of Semantic Web technologies, many of us already need a way to consistently express DwC in RDF. In particular, we need it to meet the requirements for GUID resolution (as expressed in the TDWG applicability guide) and to be able to share and aggregate diverse kinds of biodiversity metadata in the Linked Open Data world. After several months of development, stimulated by the tdwg-content discussions of last Fall, we would like to offer an ontology for consideration, based on Darwin Core terms: Darwin-SW: General site: http://code.google.com/p/darwin-sw/ Using namespace dsw = "http://purl.org/dsw/" It is a candidate for general usage, but we do not claim it is _the_ solution, and greatly respect the efforts by others to develop similar ontologies, from which we have learned much. However, for DSW, we wanted to use existing DwC terms for classes and data properties whenever possible and only create new terms when there were no existing terms that would do the job. We did feel that there was a need for clarity in how resources should be typed (i.e. rdf:type property) and for object properties that expressed the relationships among classes unambiguously. Please see the Rationale, DesignPrinciples and ClassesAndTypes wiki pages at the above address. In the ontology, we sought to embody relationships among classes based on our perception of the community consensus of what the classes represent and how they are related to each other, as expressed in posts to the tdwg-content list. Thus each class is documented carefully on the wiki with hyperlinked references to specific tdwg-content posts. We also sought to clarify or resolve issues that were raised in the list discussion, most notably the relationship among Occurrences and the evidence that documents them (i.e. tokens), and the role of "individuals". See wiki pages for the Token, Occurrence, and IndividualOrganism classes. The ontology is now in use at http://bioimages.vanderbilt.edu/, and we intend to use it more widely. We would value your opinions on the fitness of this ontology as a general solution for consistently expressing DwC concepts in RDF. Sincerely, Steve Baskauf and Cam Webb steve.baskauf(a)Vanderbilt.Edu cwebb(a)oeb.harvard.edu

Hello all: I have a few inserted comments, hopefully with some clarifying effect: On 5/4/2011 10:54 AM, Peter DeVries wrote: > Hi Steve, > > I may have overloaded the term specimen to make the explanation easier > to follow. > > A specimen could be an individual or it could be part of an individual. > > To some extent you need to think about how these models will be used. > > If you subscribe to the model that a species is whatever a taxonomists > says it is then it is difficult to make statements like. > > X% of the world's species will be extinct by 2050. > > If you mean a species as defined by the concept documented at this URI > which is supported by these specimens, images, and DNA then you are on > firmer ground. > > Species in the natural world do a pretty good job recognizing those > individuals that are appropriate mates.

The fact that human may disagree on what > species it is a human issue. > > Again, Are we modeling species or variations in human > conceptualizations of species? NMF: I believe there is a history of biodiversity database engineering that actually led some people, initially in Australia (Greg Whitbread?) and Europe (Berendsohn's group) to place more emphasis on modeling human conceptualizations of taxa. I understand this happened in the late 80s / early 90s. The motivation was, apparently, that no long-term consensus seemed available to model a single and sufficiently widely accepted taxonomy of, say, Central European vascular plant species or mosses. I believe that projects such as the Euro + Med PlantBase (http://www.emplantbase.org/home.html) are examples of the persistence (success?) of this 20+ year old practice. I think this is the kind of background that Steve is referring to. > > Which of these is of primary importance to decision makers and > non-taxonomist biologists? > Part of the problem with various publications relating to ontologies > and taxonomy is that their species models entail a specific > phylogenetic hypothesis. > > In the real world taxa are not as clean as some would like to make > them out to be. > > Each individual is a unique combination of thousands of separate gene > lineages which often do not follow clean monophyletic paths. > > I would argue that most of those who work with species related data > see them as useful typological constructs which in general follow the > biological species model. NMF: The solution of how to properly model things such as species in RDF, OWL (etc.) should ideally accommodate all "species concepts" (BCS, ESC, PSC, GSC, there's dozens), i.e. it should be neutral towards this issue. The examples below are too simple, ignoring for example cases such as pro parte synonymy, or a concept ("species") that appears unique and monophyletic to one author but (vastly) polyphyletic to another. To do an accurate mapping in that latter case (which is not super-common but it's real), I think one would have to come down on saying we're modeling human conceptualizations. They are not just that, so really it's not a strict dichotomy, meaning that by modeling conceptualizations we do not have to say "the species only exist on our heads", or "well, then anything goes". I agree (sheepishly) that it does come down to what the input data look like, and what the expectations are towards just accommodating the user community versus pushing them in a particular direction.

Second Example - SPARQL Query for Mammals Expected in Wisconsin view by Order
by Peter DeVries 03 May '11

03 May '11

Here is another example based on a different query. *Mammals expected in Wisconsin* I have bundled the screenshots and the query into this bit,ly bundle http://bit.ly/lBTFDf The SPARQL Query Looks like this. Note I am only requesting a subset of the information about each of these species. PREFIX txn: <http://lod.taxonconcept.org/ontology/txn.owl#> PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX dcterms: <http://purl.org/dc/terms/> PREFIX wisconsin: <http://sws.geonames.org/5279468/> PREFIX dbpedia_owl: <http://dbpedia.org/ontology/> select distinct ?s, ?o as ?image, ?kingdom, ?phylum, ?class, ?order, ?family, ?genus, ?sciname, ?cname, ?author where { ?s rdf:type txn:SpeciesConcept. ?s txn:inDBpediaClade dbpedia_owl:Mammal. ?s txn:isExpectedIn wisconsin:. ?s txn:kingdom ?kingdom. ?s txn:phylum ?phylum. ?s txn:class ?class. ?s txn:order ?order. ?s txn:family ?family. ?s txn:genus ?genus. ?s txn:hasScientificName ?sciname. optional {?s txn:thumbnail ?o. ?s txn:commonName ?cname. ?s txn:scientificNameAuthorship ?author}. } limit 2000 This uses the optional section so that those species that might not have a thumbnail or common name still show up in the query results. You can modify this query and run it yourself on http://uriburner.com/isparql/ Click on the "Advanced" tab to see the box for entering the query. - Pete ------------------------------------------------------------------------------------ Pete DeVries Department of Entomology University of Wisconsin - Madison 445 Russell Laboratories 1630 Linden Drive Madison, WI 53706 Email: pdevries(a)wisc.edu TaxonConcept <http://www.taxonconcept.org/> & GeoSpecies<http://about.geospecies.org/> Knowledge Bases A Semantic Web, Linked Open Data <http://linkeddata.org/> Project --------------------------------------------------------------------------------------
