hierarchies from /name/ #1699

Closed dustymc closed 5 years ago

dustymc commented 6 years ago

Can we somehow get at (in)consistent data from single records?

sharpphyl commented 6 years ago

Do you mean that if I'm about to add a taxon with a classification that's different from what's already in Arctos already, it would warn me and ask if I want to clean it up in the hierarchy tool or move everything in that genus or family to the new classification? That would be fantastic.

dustymc commented 6 years ago

I'm not sure. I think my first experiment would be a tool to just do this in the hierarchy tool.

Half-ish of the stuff in Arctos which hasn't been through the hierarchical editor is inconsistent, and it's not usually as simple as a genus being in another family. You're trying to update a family-->superfamily, the "children" of that family are in the family, some other family, no family, a bunch are directly in the superfamily, a couple subspecies don't have any classification data at all, a few more are mis-spelled, etc. That's all pretty easy to see in the hierarchical editor, but from a single record's viewpoint it's just a giant mess. I'm happy to play around with this, ideas are greatly appreciated, but I don't have a lot of hope that we're going to find a way to make data consistent in a structure designed for inconsistent data.

dustymc commented 6 years ago

This isn't practical; the queries are not very trustworthy, not very "deep" (eg, I'd have to go all the way up and all the way back down the hierarchy to ensure true consistency; that would most always involve millions of hundreds of millions of nodes), and take several minutes to run.

I added a link to auto-create and seed a hierarchy from any term in any local classification.

1) That sort of always produces errors; those are the critically-inconsistent data. 2) Sometimes (not a clue how often) that misses taxa - those are not findable by any magic I currently possess (eg, they have horrible mis-spellings or no useful classification data). I don't think there's a solution to this as long as we're managing taxonomy in a system designed to accommodate whatever anyone throws at it. Occasionally these are obvious from the hierarchy (usually in the form of "where the heck is that term?!") 3) Most hierarchies end up with an orphaned or misplaced term or two; these are caused by inconsistent data. 4) The data are now in a format which is structurally-consistent.

dustymc commented 5 years ago

The idea of finding inconsistent data in the core structure keeps coming up. I picked a sorta-random genus that's likely to be about as clean as these things get, yet big enough to almost certainly have problems, as a starting point.

UAM@ARCTOS> select count(*) from taxon_name where scientific_name like 'Microtus%';

  COUNT(*)
----------
       309

UAM@ARCTOS> select count(*) from taxon_name where scientific_name like 'Microtus%' and taxon_name_id not in (select taxon_name_id from taxon_term where term_type='genus' and term = 'Microtus' and source='Arctos');

  COUNT(*)
----------
    50

First problem: "find Microtus by {something in Arctos classification}" can't possible work because a bunch of them aren't in that source at all. (These are probably from https://github.com/ArctosDB/arctos/issues/1641#issuecomment-477822649)

That may be compelling evidence that something like a "clean backbone" is the only realistic way to have consistent data. Doing that apparently takes somewhat more resources than CoL has....

Here are the ordered "Arctos" terms for name startswith Microtus:

declare
  ct varchar2(4000);
begin
  for r in (
    select taxon_name.scientific_name,taxon_name.taxon_name_id from taxon_name where scientific_name like 'Microtus%' order by scientific_name
  ) loop
    ct:=NULL;
    for t in (
      select term, term_type from taxon_term where taxon_name_id=r.taxon_name_id and source='Arctos' and POSITION_IN_CLASSIFICATION is not null order by POSITION_IN_CLASSIFICATION) loop
      ct:=ct||t.term || ' (' || t.term_type || ')|';
    end loop;
      --dbms_output.put_line(r.scientific_name);
      dbms_output.put_line(ct);
  end loop;
end;

The gaps are the 50 without Arctos classification.

Inconsistencies are sorta-likely to jump out at people, but they're less trivial to detect with machines (there are a bunch of assumptions baked into the queries). Scroll around a bit and you should see things like...

I can get here, I think, but that just means "Microtus" is clean "upstream" - it won't get...

or any of the other not-quite-infinite number of things that could lead a user starting from a clean Microtus to not end up with the results they want.

That's not a very performant query, and if we move just a bit upstream it gets much worse.

We don't have anywhere near the processors to support a few dozen 16-minute queries anytime anyone does anything taxonomy-ish, and I don't think we have the human resources to do anything about it anyway.

I fixed the lost gull, so that's one down anyway....

These are just the most obvious reasons trying to find non-hierarchical data at useful scales in the core model is more or less futile.

Finding, fixing, or changing all of this is trivial in a hierarchy, and outliers tend to be really hard to avoid. That's where this Issue - the idea of just trying to create hierarchies and seeing what falls out - came from.

campmlc commented 5 years ago

This also supposes that we only allow Microtus to be in a single classification - Cricetidae, subfamily Arvicolinae, and not, as some research asserts and as some collections would prefer, in famly Arvicolidae. Can we allow more than one hierarchy for a given name?

The idea of finding inconsistent data in the core structure keeps coming up. I picked a sorta-random genus that's likely to be about as clean as these things get, yet big enough to almost certainly have problems, as a starting point.

First problem: "find Microtus by {something in Arctos classification}" can't possible work because a bunch of them aren't in that source at all. (These are probably from https://github.com/ArctosDB)

That may be compelling evidence that something like a "clean backbone" is the only realistic way to have consistent data. Doing that apparently takes somewhat more resources than CoL has....

Here are the ordered "Arctos" terms for name startswith Microtus:

declare ct varchar2(4000); begin for r in ( select taxon_name.scientific_name,taxon_name.taxon_name_id from taxon_name where scientific_name like 'Microtus%' order by scientific_name ) loop ct:=NULL; for t in ( select term, term_type from taxon_term where taxon_name_id=r.taxon_name_id and source='Arctos' and POSITION_IN_CLASSIFICATION is not null order by POSITION_IN_CLASSIFICATION) loop ct:=ct||t.term || ' (' || t.term_type || ')|'; end loop; --dbms_output.put_line(r.scientific_name); dbms_output.put_line(ct); end loop; end; /

We don't have anywhere near the processors to support a few dozen 16-minute queries anytime anyone does anything taxonomy-ish, and I don't think we have the human resources to do anything about it anyway.

I fixed the lost gull, so that's one down anyway....

These are just the most obvious reasons trying to find non-hierarchical data at useful scales in the core model is more or less futile.

Finding, fixing, or changing all of this is trivial in a hierarchy, and outliers tend to be really hard to avoid. That's where this Issue - the idea of just trying to create hierarchies and seeing what falls out - came from.

Jegelewicz commented 5 years ago

It seems to me that Taxonomy IS hierarchical, but Arctos decided not to treat it that way. There may be good reasons for that, but it definitely will always mean inconsistencies. Given that some people are starting to say Taxonomy as hierarchy is bunk (What’s in a Name? Taxonomy Problems Vex Biologists), maybe we have done the right thing.

BUT

We treat Higher Geography as a hierarchy and it works pretty well. I feel like we could make Taxonomy a hierarchy, create a "clean backbone" and allow multiple hierarchies for any given name if we just get some creative ideas flowing. That's just me though, I have high hopes....

dustymc commented 5 years ago

Can we allow more than one hierarchy for a given name?

Yes, absolutely - that's what http://arctos.database.museum/info/ctDocumentation.cfm?table=CTTAXONOMY_SOURCE does.

Allowing multiples in one classification is (partially) what taxon concepts exist to facilitate.

The current model is capable of holding multiple hierarchies in one source, but it'll come out as a garbled mess instead of two clear opinions - the things into which we summarize classification data behind specimen identifications are generally not structurally capable of supporting multiple opinions. Linking identifications to a single hierarchy so that we can get that single dataset for DWC and specimenresults, and more importantly to reflect what the identification was looking at, is taxon concept country.

as some collections would prefer

If those are current collections, why aren't they in their own classifications by now??

I've been thinking for a while that the 'Arctos' classification is hugely overloaded. Eg insect and mollusc people don't seem to talk, so there are a million (maybe literally!) homonyms. Putting both of those things under one roof is just asking for trouble. The same may be true for much smaller "groups" - eg, rodents. The cost of that is in limited collaboration (not my problem!), and in having a consistent way for users to find what they want without getting caught up in "local" differences (definitely my problem). I think I've been viewing those as two separate scenarios, but maybe they're one and the same and only the scale is different.

I keep finding myself facing the somehow-terrifying idea that we (Arctos as a community) should just give up on the idea of consistency within local classifications (collections can always create consistent data if they wish, and Arctos will always strive to provide tools for that) and look for it in some sort of "backbone" instead.

Taxonomy IS hierarchical

At some scales for some users, maybe. As a body of literature, absolutely not. A pure hierarchy cannot contain the ideas that Microtus-->Cricetidae and Microtus-->Arvicolidae. Arctos is perfectly capable of holding both of those hierarchies (and maybe the other thousand opinions as asserted by GlobalNames contributors) under Microtus.

Some "non-Linnean" taxonomies are explicitly non-hierarchical - eg, Getty calls itself a 'polyhierarchy' (which is a fancy word for "not a hierarchy"...).

The idea that "traditional" taxonomy is broken has been out in various forms for quite some time - eg, PhyloCode. The Arctos model is designed to accommodate that, and anything that anyone might come to think of as taxonomy in the future.

Higher Geography as a hierarchy

create a "clean backbone"

Hey, there that is again!

Higher Geography as a hierarchy

We absolutely do not. Yosemite National Park is in a state, a few counties, maybe some quads, etc.

I beg to differ - that just demonstrates that we allow multiple hierarchies for the same name.....

Containers are our one and only true structural hierarchy. The model looks like this:

UAM@ARCTOS> desc container
 Name                                  Null?    Type
 ----------------------------------------------------------------- -------- --------------------------------------------
 CONTAINER_ID                              PRIMARY KEY
 PARENT_CONTAINER_ID                           FOREIGN KEY (container.container_id)
{some random stuff for people}

Every THING has a unique identifier (and possibly a unique proxy for that identifier in "some random stuff for people" - barcode) and zero-or-one parent, which is just another container.

Container1 is contained within Container2 or it's not. That's the entirely of the possibilities.

Some of the geography (and taxonomy) data may be capable of being arranged into hierarchies, and I suppose anything can be seen as a large enough number of small enough hierarchies (which can't collectively do what hierarchies are designed to do), but the structural model of geography is only that a bunch of largely-uncontrolled terms are shoved together into a string which must be unique. There's no ordering in the data, nor in what the data represent - features can span states or be contained within counties. Taxonomy is a bit more structured (because it represents something with a bit more inherent structure), and parts of single classifications can do a very good job of simulating hierarchies in the core model.

The hierarchical editor (like GNITE and various other hierarchical editors) uses the container model, albeit with some of the "some random stuff for people" as attributes of nodes.

So if we can allow multiple higher geography "hierarchies", we should be able to do the exact same thing with taxonomy. Then we distinguish the name+classification with the authority/date and/or some unique key for the combo.If the authority/date doesn't exist, we leave it out and it gets a different key. Maybe that is taxon concepts, but it really is what we need and what everyone on the planet is doing. We cannot create the one true taxonomy - doesn't exist, and no one else has managed it. We just need something that is as functional in an applied way as possible given all the problems we cannot control. And as for "If those are current collections, why aren't they in their own classifications by now?? " NO ONE WANTS TO DO THIS - we don't have enough time and manpower to manage a single classification, much less one for each institution. THis is why MVZ is still using Arvicolinae even though they would prefer Arvicolidae. And what about teaching collections? parasite collections that span multiple phyla? We need to be able to use a single source.

This is where we need that strategic document - what PRECISELY is it that we're trying to do here? I'm not sure we're all on the same page with that, and it's impossible to get to HOW if we're not clear on WHAT.

I think comparing taxonomy to geography is comparing apples to outhouses - they're just very different THINGS. "Some taxon" may or may not encompass an individual as defined at some time by some person or entity; your opinion (as a taxonomist, identifier, and collection administrator) matters. (Although that's encroaching on identifications.) "Germany" (on some date - a component we've mostly been able to ignore via the "use current" almost-directive) does not contain "Yosemite" - there is an official map with defined borders, and your opinion does not in any way alter the one true/knowable/defined reality. At some scales (certainly individual publications, often larger) taxonomy has a predictable order - it starts somewhere around kingdom and ends somewhere around subspecies, even if the ranks aren't used. Geography does not - a feature may span several countries, countries may span multiple continents and oceans, etc. Etc., etc., etc. We should definitely be looking for things that have worked well for inspiration, but we should also be very aware of the intrinsic nature of the data we're trying to model.

There are two obvious ways to point identifications to metadata (eg, individual classifications) rather than names, and both come with their own complexities.

1) Split classifications. This has all the problems you mentioned, and also as you mentioned they're magnified for collections that don't follow traditional taxonomic boundaries. (Paleo collections are a big part of this, in addition to those you mentioned.) We might be able to mitigate some of that - eg, there's been talk of some sort of "dynamic classification" where you could build (and periodically rebuild) a "user classification" by pulling shrews from _mammalbackbone and clams from _not_insectinverts and arvicolines from _arvicolinae_according_tome and .... I'm not sure how much of that is really practical, but I think it's realistic enough to not just preemptively rule out more and smaller classifications. None of that would have any capability of pointing THIS woodrat at Cricetidae and some other woodrat in the same collection at Muridae, and I'm still not sure if ya'll (and future collections) see that as pure evil or a basic functional requirement.

2) Taxon concepts. This is clearly the most precise/powerful approach, but it also comes with the highest overhead. I think that's all in https://github.com/ArctosDB/arctos/issues/1852. Concepts absolutely can point one individual woodrat at Cricetidae and some other woodrat in the same collection at Muridae.

There certainly may be some other approach we haven't yet identified, but I can't see it from here.

None of that much addresses my problem, of getting users to everything THEY think is Cricetidae regardless of what collections have done - in fact both of those approaches probably complicates it in ways I haven't yet imagined, along with the obvious. That again looks a bit like a problem best solved by some sort of 'backbone'....
