2008-10-13T07:52:51.0012Z

you svn address also dosen't work, would you create free repository in one of these websites like github.com, www.assembla.com, google code or sourceforge?

Freebase Applications: Metaweb Perl Module

2008-10-13T07:44:54.0012Z

hi hds,

I'm interested too, actually there is two other module in cpan and none of them working becasue of latest version of JSON and JSON::XS module.

if you need someone to contribute let me know.

Bug / Feature Request: API Bug?

2008-10-13T06:47:27.0018Z

I wrote a perl script to fetch article and image from freebase but seems API has some bug:

my query is :

http://www.freebase.com/tools/queryeditor?q=%5B%7B%22/common/topic/article%22:%5B%7B%22id%22:null%7D%5D,%22/common/topic/image%22:%5B%7B%22id%22:null%7D%5D,%22guid%22:null,%22name%22:%22blood%20cancer%22,%22type%22:%22/medicine/disease%22%7D%5D&read=1

to retrive result for 'blood cancer' but the result is nothing

same query works for 'cervical cancer' but dosn't work for 'skin cancer' too

both of 'cervical cancer' and 'blood cancer' articles and content exist when is search in website

what's wrong?

actual query :

[
{
    "/common/topic/article" : [
      {
        "id" : null
      }
    ],

TV: Multiple air dates for first/final episodes???

2008-10-11T15:02:48.0017Z

So why is this the case? It's making life difficult when trying to sort search results for TV programs by air dates. Compare to Film, which has only one value for initial release date. Why is TV different?

Computer Game: Units

2008-10-10T20:27:25.0012Z

This property is specific enough to strategy games that Strategy Game and Strategy Game Unit types are probably in order. If you create these in your own domain for now (on sandbox.freebase.com), then you could add Units as a property of the Strategy Game type. That property would have an expected type of Strategy Game Unit. From there, you could augment both types with any other properties you want, such as a property that specifies whether the game is turn-based or real-time. Hope this helps, and if you need help getting started, I can create the types for you in my domain.

Birds: AOU Type

2008-10-10T17:26:31.0012Z

I've filled in a bit of data from the 49th supplement. The AOU Latin name and AOU English name types seem to be holding up well, including list imports. The supplement contains a lot of name and taxonomy changes that conflict with the ITIS data so it was a good test for how well those differences can be documented. I also added a couple text properties to document reasons for changes in nomenclature and taxonomy. This might become an enumerated list down the road.

Bug / Feature Request: Urgent Require - Fetching Content - http://www.freebase.com/api/trans/raw is not working.

2008-10-10T17:14:08.0012Z

Hi Hemang.

A recent data update seems to have caused the problem. We are working on resolving that as soon as possible. In the meanwhile if you are running this specific query for wikipedia articles only (i.e. not in a generic library or something of that sort), you can get the same content by using the /api/tran/blurb service with a very hign number for maxlength like so:

http://www.freebase.com/api/trans/blurb/%239202a8c04000641f8000000000acd66c?maxlength=3000

This will only work for wikipedia based topics. The reason being that we do not maintain the complete wikipedia article on our backend. However we do allow /api/trans/raw requests for wikipedia based topics, it simply returns the same content as the blurbs without truncating the content.

HTH

Bug / Feature Request: Deleting First Address

2008-10-10T15:40:34.0018Z

Sometimes a company in Freebase has two cities in the HQ address area when it really doesn't. If the second city is correct, and you delete the first address line, and then try to add information into the remaining line, the autofill fields won't work. You can type things in there, but the auto-suggest won't "open" and you can't link the field to an actual topic. You have to close out and then go back in.

In case that is confusing :) here's hopefully something that will help:

Company XYZ

Company/Headquarters "field"

Line 1 = Paris

Line 2 = London

Go in and delete Paris. Then try to fill in the other address fields for the London line. the fields that link to other topics won't work.

Birds: AOU Type

2008-10-10T02:02:29.0012Z

Minor revision: Latin name could be used to describe a specific instance of a taxon description (e.g., the latest edition of the AOU checklist). This will allow you to resolve ITIS English names with AOU English names linked to a single instance of the Latin name. Additional Latin names can later be added to the English names to describe changes that were made in more recent supplements or to document previous Latin names in earlier editions and supplements.

Birds: AOU Type

2008-10-10T01:39:02.0012Z

Update: I have added properties for previous and revised English and Latin names. This is so far the best way I can figure out how to explictly make those connections.

Also note that the AOU Latin names can only be linked to 1 edition of the checklist/supplement whereas common names can be linked to multiple. My thinking is that the Latin name will be used to identify the first case in which the Latin-English combo were used (only the American Flamingo data currently represent this relationship). The common name on the other hand can hold all instances of association with Latin names, editions, and supplements.

Birds: AOU Type

2008-10-10T00:34:06.0012Z

So... after playing with the AOU taxonomy type for awhile I wasn't happy with it.

I decided to let the existing Freebase English bird names drive the links between common names (linked to ITIS codes) and AOU English names. Each English bird name is type as "AOU English name" type. This type contains an "AOU Latin name" property/type that has disambiguation for taxon rank (e.g., species) and source (i.e., an edition of the AOU checklist and possibly supplement). For each AOU English name, one or more AOU Latin names can be added to track changes. For each Latin name, only one English name can be added. This means that there could be duplicate Latin names if one was changed in say the 5th edition of the checklist and then changed back in the 7th edition. Disambiguation is used to distinguish the similar Latin names topics by edition/supplement.

So far this seems to work alright. The English names are simple to update. The Latin names are where the effort must be made to keep track of changes.

Because of the way this is structured, Latin names are automatically reciprocated back to the checklist editions and supplements, which is great. Common names, however, must be reciprocated through additional properties. This adds some denormalization but I can't figure out how to get around that yet.

Birds: AOU Type

2008-10-10T00:28:27.0012Z

Ugh.... I would really rather go with a co-type, and not try to duplicate the hierarchical relationships. I was envisioning a type that would only have AOU-specific properties. I realize there may be some differences in the relationships, but I think they can be modelled without having to duplicate all the info. Perhaps when I finish resolving the names, we can get some data on how hairy the conflicts are. I don't think there will be so many differences that mirroring the Organism Classification type will be warranted.

Spaceflight: Launch/landing locations

2008-10-09T22:24:06.0012Z

That makes sense to me. The only issue I see is for missions to space stations which are not currently modeled as celestial objects, but maybe they should be...

In regard to more specific destinations, I was thinking it would be cool to make a visualization of lunar and mars landings using whatever coordinates are standard. But maybe the coordinate systems are significantly different on each planet in which case maybe it makes sense to have a 'Lunar Landing' type and a 'Mars Landing' type, etc.

Birds: AOU Type

2008-10-09T21:30:06.0012Z

Sorry. This is the updated link. The previous one will probably be recycled as the bucket for the taxonomy type, codes, and anything else AOU related.

Birds: AOU Type

2008-10-09T21:27:26.0012Z

I updated the type and changed the key. Check out AOU taxonomy and let me know what you think. Unfortunately it's complex but I think that might be a necessity to keep all the dated information together. A simpler approach would be to update the names everytime a supplement to the AOU check-list came out. However, that would require someone committed to doing that. Also, the historical information would be lost.

Birds: AOU Type

2008-10-09T19:25:38.0012Z

My suggestion:

I don't see any way to do this except to add an AOU taxonomy CVT for each bird taxon’s English name. The CVT would link the AOU English name to its organism rank, Latin name, AOU edition, and AOU supplement. Both the English and Latin names can change over time so all this information needs to be stored together. Following the current Freebase format, the English name should be the topic described by the CVT. The higher and lower AOU taxa ranks probably need to be included in the AOU CVT too.

If the AOU English name is the same as the ITIS English name then the topic will have both types. If the AOU name is different than ITIS then it will only have one or the other type. There is no way to properly "resolve" these different taxonomic systems. They are similar but different and both change over time. The changes within each system need to be maintained. Perhaps a “most similar ITIS taxon” property is needed, especially for those bird topics that do not have the same AOU and ITIS common names. Alternatively, we could use a more generic “equals”, “overlaps”, “contains”, and “contained by” properties for defining relationships among taxon topics associated with multiple taxonomies.

I've brought this non-overlapping category issue up a few times now under the umbrella of "crosswalks" in various discussions, including those related to taxonomy. I still think they are a necessity. The world is categorized by different people in different ways. In this case, ITIS circa 2007 is not going to work as a one-size-fits-all taxonomic system. There are dozens of other taxonomies, including AOU. Freebase provides an amazing tool for describing relationships among taxonomies and other categorical classification systems. This ITIS/AOU conflict provides yet another example of how categories can be crosswalked in Freebase. Land cover classification schemes provide another.

I'm working on an AOU taxonomy type but the current version of the UI is stymieing me again by not allowing me to delete properties or change the key. The draft is: http://www.freebase.com/type/schema/user/spatialed/bird_codes/aou Ignore the properties below AOU supplement. The AOU code properties will need to be added separately, possibly within an AOU bucket type that contains the taxonomy CVT and a standard type with additional properties that do not need to be directly linked to the taxonomy.

Spaceflight: Split spacecraft and missions

2008-10-09T19:22:57.0012Z

I'd rather get it right from the beginning, and pick one type for topic imported from WP, and create new topics as needed. I mean, do this if you're adding types by hand. If someone (or a bot) has already added both (or all three!) types, flagging it for split seems sufficient.

Spaceflight: Split spacecraft and missions

2008-10-09T18:32:10.0017Z

In email yesterday, evening asked me about what to do when a spacecraft is conflated with a mission. This sometimes also happens with space programs, eg. see International Space Station.

Usually this comes from Wikipedia having conflated the two. I say we type the topic as both things and mark it for split.

Thoughts?

Spaceflight: Launch/landing locations

2008-10-09T18:30:04.0012Z

Well, I see two properties here:

1) Destination (expected: celestial object) -- for missions that go to another planet or whatever, whether they return or not

2) Landing site (expected: geolocation) -- for missions that land back on earth

The description/help for each of these would help distinguish them.

Birds: AOU Type

2008-10-09T17:49:59.0012Z

great -- looking forward to seeing what you come up with. i will probably be resolving names for a little while yet, but when that is done, i can help populate that type.

Birds: AOU Type

2008-10-09T17:17:49.0012Z

That's funny you should write this right now. I noticed your question as I was about to start this exact type. I was wondering how to organize it and agree that an AOU type would be a good way to go. I'll take a crack at it. Let me know if you think anything should be added or changed.

Spaceflight: Launch/landing locations

2008-10-09T00:09:21.0001Z

What about space missions that land on celestial objects such as comets or other planets? Clearly a landing location can't be a geolocation in this case. Perhaps another property (or property of a type that includes the space mission type) with an ECT of /astronomy/celestial_object would be appropriate. This of course begs the question of how to specify the specific location on the celestial object. For spherical objects (such as the moon), there must be an analogue of long/lat. Maybe someone else can weigh in on this issue.

Spaceflight: Launch/landing locations

2008-10-08T20:12:47.0017Z

I notice that some space missions are co-typed as locations because mw_coord_bot picked up their lat/long from infoboxes on wikipedia. This is obviously incorrect, but recording launch and landing locations could be useful and interesting. Could we put these as properties on space mission? I suspect the launch location should just be type /location/location (or else some kind of type that includes that, like "Space mission launchsite" in this domain), but landing location should probably be a geolocation since so many of them are at sea, in the middle of nowhere, etc.
