Help Center: Converting freebase dump to RDF

2008-11-21T05:16:03.0017Z

Hi Guys,

I looked through data dump available from Freebase site but couldn't figure it out how to convert this into RDF. I need help in form of tool or just simple description of this format and how it relates to rdf.

Help Center: ID and GUID problem

2008-11-18T19:47:11.0101Z

Reconciling an existing database with Freebase can be a challenging task because Freebase has so much information that you often have several topics that share the same name. For example, Freebase has 179 different topics all named "London".

If you know the Freebase type that you're looking for you can use the Reconciliation Service to get a ranked list of cities named London, for example. In practice, a lot of the terms will have an obvious match but many of them will still have to be reconciled manually or by using additional heuristics.

Once, you've reconciled each topic in your database with its corresponding Freebase topic ID you can query the Read Service for the properties of an individual entry. There are no "primary properties" per se, just different views of a topic's properties depending on which type you're looking at.

I recommend reading the first two chapters of the MQL Reference Guide. to help famililiarize yourself with some of the basic concepts.

Help Center: ID and GUID problem

2008-11-18T15:21:28.0012Z

I have a database that isn't ported to freebase. It was easier to link with the Freebase topics (like George W. Bush).

How do I do a nested query by id/name/keyword and return 1 guid,

take that guid and query its primary properties?

HI Narphorium,

Thanks very much, found it. Appreciate your help.

Help Center: ID and GUID problem

2008-11-18T05:29:40.0018Z

Some Freebase topics (like George W. Bush) use Wikipedia keys as their ID but there is no rule that says that they have to. By default, Freebase assigns the GUID as the ID.

Why is this breaking your website? Freebase-suggest should be giving you the correct ID (/guid/9202a8c04000641f80000000047953d8) when you handle the fb-select event. Then you just append it to http://www.freebase.com/view and you have a valid link to that topic.

From your home page click on My Types and then click on the Kampung Museum type. This will show your table in "schema view". At the top right of that view there should be a tiny link that says delete.

Bug / Feature Request: Profile RSS Feed

2008-11-17T21:12:09.0018Z

Hi all,

Congrats about a great product your building here, it ~~could~~ will change the way we find information online. I'll definetly be spreading the word about it over here in the UK dont you worry! and I'm certainly pretty excited to see how it evolves over time.

While playing around, I've noticed that the RSS Feed for my profile page doesnt seem to be working:

http://www.freebase.com/feed/newsfeed/profile/user/simonturner

Be handy to have. Is this a one of bug, or is it something thats a work in progress? Also I had a little trouble tracking down the Freebase Discussion Forum and actually had to resort to a google search lol. How do you normally browse to it, just wondering if it should be a little more prominent.

My Exercises base is comming along nicely, but there's still lots to do. I've pretty much tapped into all the data that was fead in from Wikipedia, so the next step is going to be to start created some fresh content.

Cheers,

Simon

Help Center: php query - include ANY match with criteria

great! thanks for your time.

Help Center: php query - include ANY match with criteria

2008-11-16T08:53:14.0012Z

I don't think its possible to do that all in one query. You'll have to build a seperate query for each term and merge the results in your application.

Luckily Freebase allows you to send multiple queries at once. An example of how this is done is shown on page 2 of the cheatsheet.

Help Center: php query - include ANY match with criteria

2008-11-15T23:48:02.0012Z

awesome, thanks!

do you have any idea how to get this done, but with many different terms? the "|=" works to check for multiple terms, but it looks for an exact match, while the "~=" will only accept one parameter...

2008-11-15T22:55:49.0012Z

The MQL Cheatsheet covers this exact problem under Textual Comparisons.

In your case, I think you just need to add the following line:

"name~=" => "love",

2008-11-15T18:18:55.0017Z

Hi,I have a rather simple question about a query in php, I would just like my result to return (in this case) any album name which contains the word "love". For the moment, it just spits out all albums...I'm not sure how to get it to narrow down with this criteria

       "type" => "/music/album",
      "limit" => 200,
         "name" => array()));

Thanks!

None: Absence of information vs. information of absence

2008-11-14T15:26:19.0012Z

I read his response but couldn't cut through the jargon, to be quite honest. It seemed as if he agreed that typing "none" and keeping it as a topic was an acceptable solution, but I just can't see how that can be. It's a novelty on Freebase, to be sure, but it certainly goes against the legitimacy of a data set when one of the items a) doesn't exist and b) doesn't exist with the types of relationships that it claims to. I'll open a ticket in the bug tracking system to this effect, but if what you say is true, I don't know that it'll do any good.

Scott Meyer seemed to indicate on the data-modeling list that the graph-level folks were not interested in implementing this. I'll vote on this ticket if someone from Metaweb opens it but I suspect that the issue is pretty much decided now.

2008-11-14T05:59:08.0012Z

Yes, I don't know the specifics of how they weight the terms but if you search for "arnold" using the Search API you will see that each result has a relevence:score and that "Arnold Schwartzenegger" is ranked first.

Help Center: Freebase is easy and adequte DB for mining data?

2008-11-14T03:28:10.0012Z

Thanks a lot, narphorium

I think Freebase is quite well for people discovering themself, open, large as its name. I'm asking myself:

- Does freebase evaluate the weight of a term? for instance, if I type "arnol", freebase suggests me "Arnold Schwarzenegger" in the first list. It means "Arnold Schwarzenegger" is more important than others?

None: Absence of information vs. information of absence

2008-11-13T19:34:44.0012Z

I'd suggest raising a ticket in our bug tracking system, describing in detail the problem being addressed and your proposed solution. This is probably a graph-level change, so we can then pass it over to that team for evaluation.

2008-11-13T14:21:41.0012Z

Yes! This is a great idea. How do we get this to happen?

Help Center: Freebase is easy and adequte DB for mining data?

2008-11-13T07:44:35.0012Z

Topics are related to each other in MQL using links. Each link has a source a target and a property so in your example, the source is /en/barack_obama, the target is /people/person and the property is /type/object/type. This is what's commonly known as an is-a relationship but there are many different relations available in Freebase as you can see here.

Another common relation between topics is broader/narrower. This type of relation is used in several places in Freebase like Organism Classification, Location, File Format & Profession. I have started mapping some of these common relationships onto the SKOS ontology which is a popular framework for this type of work.

Hi narphorium,

I found it is ok, but I'm wondering :

- How topics have their relationship in Metaweb?

- We could name these relationship, for example: "parent-child" in "human-Obama" and other relationships if it has?

I query by using MQL, but I understand it not clearly.

2008-11-11T06:05:38.0012Z

In Freebase, most of the topics are named entities like "software". Actions like "repair" are mostly represented in the schema as properties. If you'd like to model the relationship between "action" words and their corresponding Freebase properties I've created a simple type that can represent those relations for you. Once you've entered a bunch of those relations you should be able to start data mining some text. Another user was asking a similar question on the developer mailing list last week

Thinkbase is a really cool application that lets you browse through the relationships between Freebase topics. If you want to find those releationships in MQL you need to query the underlying links like this.

Help Center: Freebase is easy and adequte DB for mining data?

2008-11-11T02:07:49.0005Z

Hi my friends,

I was wondering some questions:

- First, I want to devided our topics into 2 groups: topics have action like "repair" and topics don't have action like "software".

- Second, I like discovering the relation among "real" topics that are not "types","domains" or "bases", for example:

Topic "Obama" and topic "human", it's clear to see " Obama is an instance of huma", so that we can say "Obama" belongs to "human", and "human" is "parent" of "Obama".

We can do it by MQL query? or by any others ways in freebase?

Thank you.

Domains and Types: wrong type?

2008-11-10T15:32:32.0012Z

I would think that this is a dining style or method or custom... A dining custom, that's what I think it is. Not a dish.

Domains and Types: wrong type?

2008-11-10T00:24:31.0011Z

I don't see how this is a dish type. Toby added that type to this topic so maybe I'm missing something butlooks wrong to me.

Domains and Types: National Laboratory type?

2008-11-09T17:33:52.0018Z

Do you think there should be a new National Laboratory type modeled? This one, for example, is one of a number run by the US Government Agency, the Department of Energy - see the drop down list of national labs on the DOE site here:

It also makes me wonder if Brookhaven (and other labs) are correctly typed as Company.
