Freebase

Shared publicly  - 
 
As previously announced [1], Freebase will be going read-only next Tuesday, March 31st. This means that the website will no longer accept edits and the MQL write API will be retired. 

In that announcement we also promised updates on the Wikidata import review tool and transition plan for the Freebase Search API & Suggest Widget to a Knowledge Graph-based solution.

The Primary Sources tool will have two parts: a front end integrated into the Wikidata User Interface and a back end running on Wikimedia labs to provide data to the front end. Shortly after read-only, we will start with a small set of data in order to get feedback from the community and refine the tool.
- Screenshot and more info: https://www.wikidata.org/wiki/Wikidata:Primary_sources_tool 
- Code will be available by the end of the month here: https://github.com/google/primarysources
- FAQ by the Wikidata community: https://www.wikidata.org/wiki/Help:FAQ/Freebase 
- Discussion: https://www.wikidata.org/wiki/Wikidata:WikiProject_Freebase

The new Knowledge Graph API should be publicly available as a beta sometime during calendar Q2. We will ensure that there are at least three full months between the launch of that beta and the retirement of the current Freebase APIs, so this does mean the original June 30th retirement date will be pushed out. In the meantime, here are a few more details about the new API:
- Enables searching for Knowledge Graph entities by text or MID
- Returns name, subtitle, image, description and URL for candidate matches
- Results can also be restricted to a specific language or type
- Uses schema.org vocabulary in the JSON-LD format
- Companion Freebase Suggest-like Javascript library

+Shawn Simister and I had an opportunity to run a  +Freebase  workshop at +SemanticWeb.com #SemTechBiz conference in San Jose, CA this week as a part of the  #LODLAM  training day. You can find the workshop deck here: http://goo.gl/WTxgIw.
The exercises focus on using the +Freebase RDF data dump with the open source Cayley graph database (https://github.com/google/cayley) and BigQuery (https://developers.google.com/bigquery). We also show how one can perform Freebase data joins with Wikipedia logs and gain some insight :) 
Code snippets are in the speaker notes so you can quickly copy, paste and run them. It was a lot of fun for us and I hope you'll find this workshop enjoyable, too! Please let us know if any of the steps are not clear so we can improve the instructions.

Seevl is opening up their music recommendation engine to developers through a JSON-LD API.
Today another music startup is throwing its hat into the music meta-data ring. Dublin-based Seevl has released an API for developers to let them easily add..

Highly contextual apps rely on a having good quality background knowledge about the real world. Combining Freebase data with Android Wear could help users get  the right information at the right time about the entities that they care about.
 
I am working on an Android Wear codelab. I tried the RecipeAssistant example and it works perfect. Now I am adding additional features using +Freebase  and +YouTube  APIs.
I will give this codelab next April 10, in an event organized by the +GDG Santa Fe , and after that I will release the code of the project and codelab slides.

Research using Freebase data grew again in 2013. We cataloged 68 new papers (versus 59 in 2012) in our +Mendeley group (http://goo.gl/qhLOq).

Trending topics of research for 2013 included natural language processing (11 papers), relation extraction (10) and entity linking (6). Linked data (6) and RDF (3) continued to rank highly as they did in 2012.

If you're working on a research project that touches on any of these topics you should take a look at the Freebase RDF data dump (https://developers.google.com/freebase/data). Its free with attribution and contains high-quality, structured data about 42M+ real-world entities.

If you've ever wondered how Google determines which data to trust in Freebase, this research paper gives a rare glimpse into one of the algorithms used to estimate the quality of individual contributions.

Great posts guys but I have a question. Does anybody know how google treats websites that uses free base content? We all know that Google is big on sites with original content but in the case of free base, I'm not sure what the intent is. Thoughts anyone?

Freebase

When we publicly launched Freebase back in 2007, we thought of it as a "Wikipedia for structured data." So it shouldn't be surprising that we've been closely watching the Wikimedia Foundation's project Wikidata[1] since it launched about two years ago. We believe strongly in a robust community-driven effort to collect and curate structured knowledge about the world, but we now think we can serve that goal best by supporting Wikidata -- they’re growing fast, have an active community, and are better-suited to lead an open collaborative knowledge base.

So we've decided to help transfer the data in Freebase to Wikidata, and in mid-2015 we’ll wind down the Freebase service as a standalone project. Freebase has also supported developer access to the data, so before we retire it, we’ll launch a new API for entity search powered by Google's Knowledge Graph.

Loading Freebase into Wikidata as-is wouldn't meet the Wikidata community's guidelines for citation and sourcing of facts -- while a significant portion of the facts in Freebase came from Wikipedia itself, those facts were attributed to Wikipedia and not the actual original non-Wikipedia sources. So we’ll be launching a tool for Wikidata community members to match Freebase assertions to potential citations from either Google Search or our Knowledge Vault[2], so these individual facts can then be properly loaded to Wikidata. 

We believe this is the best first step we can take toward becoming a constructive participant in the Wikidata community, but we’ll look to continually evolve our role to support the goal of a comprehensive open database of common knowledge that anyone can use.

Here are the important dates to know:

Before the end of March 2015
- We’ll launch a Wikidata import review tool
- We’ll announce a transition plan for the Freebase Search API & Suggest Widget to a Knowledge Graph-based solution

March 31, 2015
- Freebase as a service will become read-only
- The website will no longer accept edits 
- We’ll retire the MQL write API

June 30, 2015
- We’ll retire the Freebase website and APIs[3]
- The last Freebase data dump will remain available, but developers should check out the Wikidata dump[4]

+Bernard Vatant you have a point, since a Wikidata founder & director is now employed by Google, it seems like the open-source version of Google ACQUIRING a company and its technology, not RETIRING a service.  Answering questions directly in the SERPs is Google's future of search.  Bearing in mind that Google’s mission is to organize the world’s information and make it universally accessible and useful, I imagine the future of Google search as an android with AI that can hold a conversation. There will be no need to visit other websites. Sure, you can check the source of a fact if you want, but most users won't bother - just like the way they use Wikipedia.  I see this move simply as the route Google has found to bring into its fold a means to compete with what Wikipedia provides.

From 0 to hero with Cayley in 1m 48sec.
Here's a quick screencast I recorded to help you query a subset of +Freebase with Cayley, an open source graph database written in #golang .
If you enjoy the video, check out more examples from our #lodlam (http://lodlam.net/) #semtechbiz  workshop here: http://goo.gl/WTxgIw.

+Freebase when ever I try to "create a new account" on freebase I pick a "username" and I always get the same response no matter what name I place in (no spaces lower case) - "Account is already connected to a Freebase user."  what do I need to do to create an freebase account?

+Denny Vrandečić has built qLabel; an open source JavaScript library that looks up and displays the labels of entities marked-up in a Web site in the language of the user viewing it. Every entity is marked up with a URI, which is then used to look up the labels in the requested language. You can use any URI that supports look-up using Linked Data standards, in particular +Freebase and Wikidata but you can also publish your own set of entities and labels as RDF or JSON-LD and use them — and at the same time release them to the Semantic Web!

While you can download the Freebase Data Dumps in N-triples RDF format at https://developers.google.com/freebase/data many developers find them a bit intimidating due to their large size (250GB+ uncompressed) and format. We’d like to help. In this pilot “Making Sense of The Graph”   #GDL  episode,  +Jarek Wilkiewicz  and +Dan Brickley  introduce you to a simple way to experiment with Freebase RDF Data Dumps with SPARQL and  +OpenLink Software  Virtuoso by using a pre-packaged distribution created by  +Sindicetech LTD. You can find the  +Google Cloud Platform  GCE image and instructions at: 
https://groups.google.com/forum/#!forum/sindicetech-freebase and more information at http://www.sindicetech.com/freebase.  
Please let us know what you think and please suggest topics for future “Making Sense of The Graph” episodes you’d like to see us cover.

Seevl has built a recommendation engine for obscure hipster bands you've probably never heard of.
 
Yes, #Freebase  data can be used to hipster-ify yourself, give a try at our hack from this week-end :-)

http://hipster.seevl.fm - build via the +seevl API, using data from +Freebase +Wikipedia +MusicBrainz and more

This paper from Microsoft Research explains how they use Freebase data and user click logs to create personalized recommendations for related entities like the ones you see in Google's Knowledge Graph.
