Beta-Test Updates

While everyone at the DBpedia Association was preparing for the SEMANTiCS Conference in Vienna, we also managed to reach an important milestone regarding the beta-test for our data release tool.

First and foremost, already 3500 files have been published with the plugin. These files will be part of the new DBpedia release and are available on our LTS repository.

Secondly, the documentation of the testing has been brought into good shape. Feel free to drop by and check it out.
Thirdly, we reached our first interoperability goal. The current metadata is sufficient to produce RSS 1.0 feeds. See here for further information. We also defined a loose roadmap on top of the readme, where interoperability to DCAT and DCAT-AP has high priority.

 

Now we have some time to support you and work one on one and also prepare the configurations to help you set up the data releases. Lastly, we already received data from DNB and SUMO, so we will start to look into these more closely.

Thanks to all the beta-testers for your nice work.

We keep you posted.

Meet the DBpedia Chatbot

This year’s GSoC is slowly coming to an end with final evaluations already being submitted. In order to bridge the waiting time until final results are published, we like to draw your attention to a former project and great tool that was developed during last years’ GSoC.

Meet the DBpedia Chatbot. 

DBpedia Chatbot is a conversational Chatbot for DBpedia which is accessible through the following platforms:

  1. A Web Interface
  2. Slack
  3. Facebook Messenger

Main Purpose

The bot is capable of responding to users in the form of simple short text messages or through more elaborate interactive messages. Users can communicate or respond to the bot through text and also through interactions (such as clicking on buttons/links). There are 4 main purposes for the bot. They are:

  1. Answering factual questions
  2. Answering questions related to DBpedia
  3. Expose the research work being done in DBpedia as product features
  4. Casual conversation/banter
Question Types

The bot tries to answer text-based questions of the following types:

Natural Language Questions
  1. Give me the capital of Germany
  2. Who is Obama?
Location Information
  1. Where is the Eiffel Tower?
  2. Where is France’s capital?
Service Checks

Users can ask the bot to check if vital DBpedia services are operational.

  1. Is DBpedia down?
  2. Is lookup online?
Language Chapters

Users can ask basic information about specific DBpedia local chapters.

  1. DBpedia Arabic
  2. German DBpedia
Templates

These are predominantly questions related to DBpedia for which the bot provides predefined templatized answers. Some examples include:

  1. What is DBpedia?
  2. How can I contribute?
  3. Where can I find the mapping tool?
Banter

Messages which are casual in nature fall under this category. For example:

  1. Hi
  2. What is your name?

if you like to have a closer look at the internal processes and how the chatbot was developed, check out the DBpedia GitHub pages. 

DBpedia Chatbot was published on wiki.dbpedia.org and is one of many other projects and applications featuring DBpedia.

DBpedia Entity – Standard Test Collection for Entity Search over DBpedia

Today we are featuring DBpedia Entity, in our blog series of introducting interesting DBpedia applications and tools to the DBpedia community and beyond. Read on and enjoy.

DBpedia-Entity is a standard test collection for entity search over the DBpedia knowledge base. It is meant for evaluating retrieval systems that return a ranked list of entities (DBpedia URIs) in response to a free text user query.

The first version of the collection (DBpedia-Entity v1) was released in 2013, based on DBpedia v3.7 [1]. It was created by assembling search queries from a number of entity-oriented benchmarking campaigns and mapping relevant results to DBpedia. An updated version of the collection, DBpedia-Entity v2, has been released in 2017, as a result of a collaborative effort between the IAI group of the University of Stavanger, the Norwegian University of Science and Technology, Wayne State University, and Carnegie Mellon University [2]. It has been published at the 40th International ACM SIGIR Conference on Research and Development in Information Retrieval (SIGIR’17), where it received a Best Short Paper Honorable Mention Award. See the paper and poster.

DBpedia Entity was published on wiki.dbpedia.org and is one of many other projects and applications featuring DBpedia.

Beta-tests for the DBpedia Databus commence

Finally, we are proud to announce that the beta-testing of our data release tool for data releases on the DBpedia Databus is about to start.

In the past weeks our developers at DBpedia  have been devloping a new data release tool to release datasets on the DBpedia Databus. In that context we are still looking for beta-testers who have a dataset they wish to release.  Sign up here and benefit from an increased visibility for your dataset and your work done.

We are now preparing the first internal test with our own dataset to ensure the data release tool is ready for the testers. During the testing process, beta-testers will discuss occuring problems, challenges and ideas for improvement via the DBpedia #releases channel on Slack to profit from each other’s knowledge and skills. Issues are documented via GitHub.

The whole testing process for the data release tool follows a 4-milestones plan:

Milestone One: Every tester needs to have a WebID to release data on the DBpedia Databus. In case you are interested in how to set up a WebID, our tutorial will help you a great deal.

Milestone Two: For their datasets, testers will generate DataIDs, that provide  detailed descriptions of the datasets and their different manifestations as well as relations to agents like persons or organizations, in regard to their rights and responsibilities.

Milestone Three: This milestone is considered as achieved, if an RSS feed feature can be genreated. Additionally, bugs, that arose during the previous phases should have been fixed. We also want to collect the testers particular demands and wishes that would benefit the tool or the process. A second release can be attempted to check how integrated fixes and changes work out.

Milestone Four: This milestone marks the final upload of the dataset to the DBedia Databus which is hopefully possible in about 3 weeks.

 

In case you want to get one of the last spots in the beta-testing team, just sign up here and get yourself a WebID and start testing.

Looking forward to working with you…

Yours,

DBpedia Association

French DBpedia enthusiasts joined the meetup in Lyon.

Rencontre avec les français DBpédiens à Lyon

In cooperation with Thomas Riechert (HTWK/InfAI), the DBpedia Association organized our second DBpedia meetup this year, this time in Lyon. On July 3rd, 2018, we met the French DBpedia Community at the ENS in person and presented the vision of the new DBpedia Databus, an opportunity which simplifies the work with data.

First and foremost, we would like to thank the Institute for Applied Informatics for supporting our community and the LARHRA Laboratory as well as the ENS for hosting our community meetup. Special thanks go to Thomas Riechert and Vincent Alamercery (LARHRA Lyon) for organizing the event.

Opening Session

Sebastian Hellmann opened up the meetup in Lyon.

Sebastian Hellmann (AKSW/KILT) opened up the meetup in Lyon by introducing the DBpedia development strategy and the new DBpedia Databus to the French DBpedia community (slides). Afterwards, Elmahdi Korfed from INRIA presented new features and tools as results developed in  the French DBpedia chapter (slides):

In the following months, Elmahdi plans to work on the DBpedia historic live version and the DBpedia wiki commons. His research will be presented during our 12th DBpedia Community meeting on September 10th, in Vienna.

Elmahdi Korfed from INRIA presented new features developed in the French DBpedia chapter.

Following Elmahdi, Francesco Beretta presented LARHRA laboratory and its different research areas. In particular, he introduced the Data for History Consortium which is an international consortium founded in 2017 with the aim of improving geo-historical data interoperability in the semantic web.

DBpedia at LSWT 2018

Unfortunately, with the new GDPR, we experienced some trouble with our Blog. That is why this post is published a little later than anticipated.

There you go.

With our new strategic orientation and the emergence of the DBpedia Databus, we wanted to meet some DBpedia enthusiasts of the German DBpedia Community.

The recently hosted 6th LSWT (Leipzig Semantic Web Day) on June 18th, was the perfect platform for DBpedia to meet with researchers, industry and other organizations to discuss current and future developments of the semantic web.

Under the motto “Linked Enterprises Data Services”, experts in academia and industry talked about the interlinking of open and commercial data of various domains such as e-commerce, e-government, and digital humanities.

Sören Auer, DBpedia endorser and board member as well as director of TIB, the German National Library of Science and Technology, opened the event with an exciting keynote. Recapping the evolution of the semantic and giving a glimpse into the future of integrating more cognitive processes into the study of data,  he highlighted the importance of AI, deep learning, and machine learning. They are as well as cognitive data, no longer in their early stages but advanced to fully grown up sciences.

Shortly after, Sebastian Hellmann, director of the DBpedia Association, presented the new face of DBpedia as a global open knowledge network. DBpedia is not just the most successful open knowledge graph so far, but also has a deep inside knowledge about all connected open knowledge graphs (OKG) and how they are governed. 

With our new credo connecting data is about linking people and organizations, the global DBpedia platform aims at sharing efforts of OKG governance, collaboration, and curation to maximize societal value and develop a linked data economy.

 

The DBpedia Databus functions as Metadata Subscription Repository, a platform that allows exchanging, curate and access data between multiple stakeholders. In order to maximize the potential of your data, data owners need a WebID to sign their Metadata with a private key in order to make use of the full Databus services.  Instead of one huge monolithic release every 12 months the Databus enables easier contributions and hence partial releases (core, mapping, wikidata, text, reference extraction) at their own speed but in much shorter intervals (monthly). Uploading data on the databus means connecting and comparing your data to the network. We will offer storage services, free & freemium services as well as data-as-a-service.  A first demo is available via http://downloads.dbpedia.org/databus

During the lunch break, LSWT participants had time to check out the poster presentations. 4 of the 18 posters used DBpedia as a source. One of them was Birdory, a memory game developed during the Coding Da Vinci hackathon, that started in April 2018. Moreover, other posters also used the DBpedia vocabulary.

Afternoon Session

In the afternoon, participants of LSWT2018 joined hands-on tutorials on SPARQL and WebID. During the SPARQL tutorial, ten participants learned about the different query types, graph patterns, filters, and functions as well as how to construct SPARQL queries step by step with the help of a funny Monty Python example.

Afterwards, DBpedia hosted a hands-on workshop on WebID, the password-free authentication method using semantics. The workshop aimed at enabling participants to set up a public/private key, a certificate, and a WebID.  Everything they needed to bring was a laptop and an own webspace. Supervised by DBpedia’s executive director Dr. Sebastian Hellmann and developer Jan Forberg, people had to log-into a test web service at the end of the session, to see if everything worked out. All participants seemed well satisfied with the workshop –  even if not everyone could finish it successfully they got a lot of individual help and many hints. For support purposes, DBpedia will stay close in touch with those participants.

 

Thanks to Institut für Angewandte Informatik as well to the LEDS -project and eccenca for organizing LSWT2018 and keeping the local semantic web community thriving.

 

Upcoming Events:

We are currently looking forward to our next DBpedia meetup in Lyon, France on July 3rd and the DBpedia Day co-located with Semantics 2018 in Vienna. Contributions to both events are still welcome. Send your inquiry to dbpedia@infai.org.

The DBpedia Databus – transforming Linked Data into a networked data economy

Working with data is hard and repetitive. That is why we are more than happy to announce the launch of the alpha version of our DBpedia Databus, a way that simplifies working with data. 

We have studied the data network for already 10 years and we conclude that organizations with open data are struggling to work together properly. Even though they could and should collaborate, they are hindered by technical and organizational barriers. They duplicate work on the same data. On the other hand, companies selling data cannot do so in a scalable way. The consumers are left empty-handed and trapped between the choice of inferior open data or buying from a jungle-like market. 

We need to rethink the incentives for linking data

Vision

We envision a hub, where everybody uploads data. In that hub, useful operations like versioning, cleaning, transformation, mapping, linking, merging, hosting are done automagically on a central communication system, the bus, and then again dispersed in a decentral network to the consumers and applications.  On the Databus, data flows from data producers through the platform to the consumers (left to right), any errors or feedback flows in the opposite direction and reaches the data source to provide a continuous integration service and improves the data at the source.

The DBpedia Databus is a platform that allows exchanging, curating and accessing data between multiple stakeholders. Any data entering the bus will be versioned, cleaned, mapped, linked and its licenses and provenance tracked. Hosting in multiple formats will be provided to access the data either as dump download or as API.

Publishing data on the Databus means connecting and comparing your data to the network

If you are grinding your teeth about how to publish data on the web, you can just use the Databus to do so. Data loaded on the bus will be highly visible, available and queryable. You should think of it as a service:

  • Visibility guarantees, that your citations and reputation goes up.
  • Besides a web download, we can also provide a Linked Data interface, SPARQL-endpoint, Lookup (autocomplete) or other means of availability (like AWS or Docker images).
  • Any distribution we are doing will funnel feedback and collaboration opportunities your way to improve your dataset and your internal data quality.
  • You will receive an enriched dataset, which is connected and complemented with any other available data (see the same folder names in data and fusion folders).

 How it works at the moment

Integration of data is easy with the Databus. We have been integrating and loading additional datasets alongside DBpedia for the world to query. Popular datasets are ICD10 (medical data) and organizations and persons. We are still in an initial state, but we already loaded 10 datasets (6 from DBpedia, 4 external) on the bus using these phases:

  1.  Acquisition: data is downloaded from the source and logged in.
  2. Conversion: data is converted to N-Triples and cleaned (Syntax parsing, datatype validation, and SHACL).
  3. Mapping: the vocabulary is mapped on the DBpedia Ontology and converted (We have been doing this for Wikipedia’s Infoboxes and Wikidata, but now we do it for other datasets as well).
  4. Linking: Links are mainly collected from the sources, cleaned and enriched.
  5. IDying: All entities found are given a new Databus ID for tracking.
  6.  Clustering: ID’s are merged onto clusters using one of the Databus ID’s as cluster representative.
  7. Data Comparison: Each dataset is compared with all other datasets. We have an algorithm that decides on the best value, but the main goal here is transparency, i.e. to see which data value was chosen and how it compares to the other sources.
  8. A main knowledge graph fused from all the sources, i.e. a transparent aggregate.
  9. For each source, we are producing a local fused version called the “Databus Complement”. This is a major feedback mechanism for all data providers, where they can see what data they are missing, what data differs in other sources and what links are available for their IDs.
  10. You can compare all data via a web service.

Contact us via dbpedia@infai.org if you would like to have additional datasets integrated and maintained alongside DBpedia.

From your point of view

Data Sellers

If you are selling data, the Databus provides numerous opportunities for you. You can link your offering to the open entities in the Databus. This allows consumers to discover your services better by showing it with each request.

Data Consumers

Open data on the Databus will be a commodity. We are greatly downing the cost of understanding the data, retrieving and reformatting it. We are constantly extending ways of using the data and are willing to implement any formats and APIs you need. If you are lacking a certain kind of data, we can also scout for it and load it onto the Databus.

Is it free?

Maintaining the Databus is a lot of work and servers incurring a high cost. As a rule of thumb, we are providing everything for free that we can afford to provide for free. DBpedia was providing everything for free in the past, but this is not a healthy model, as we can neither maintain quality properly nor grow.

On the Databus everything is provided “As is” without any guarantees or warranty. Improvements can be done by the volunteer community. The DBpedia Association will provide a business interface to allow guarantees, major improvements, stable maintenance, and hosting.

License

Final databases are licensed under ODC-By. This covers our work on recomposition of data. Each fact is individually licensed, e.g. Wikipedia abstracts are CC-BY-SA, some are CC-BY-NC, some are copyrighted. This means that data is available for research, informational and educational purposes. We recommend to contact us for any professional use of the data (clearing) so we can guarantee that legal matters are handled correctly. Otherwise, professional use is at own risk.

Current Statistics

The Databus data is available at http://downloads.dbpedia.org/databus/ ordered into three main folders:

  • Data: the data that is loaded on the Databus at the moment
  • Global: a folder that contains provenance data and the mappings to the new IDs
  • Fusion: the output of the Databus

Most notably you can find:

  • Provenance mapping of the new ids in global/persistence-core/cluster-iri-provenance-ntriples/<http://downloads.dbpedia.org/databus/global/persistence-core/cluster-iri-provenance-ntriples/> and global/persistence-core/global-ids-ntriples/<http://downloads.dbpedia.org/databus/global/persistence-core/global-ids-ntriples/>
  • The final fused version for the core: fusion/core/fused/<http://downloads.dbpedia.org/databus/fusion/core/fused/>
  • A detailed JSON-LD file for data comparison: fusion/core/json/<http://downloads.dbpedia.org/databus/fusion/core/json/>
  • Complements, i.e. the enriched Dutch DBpedia Version: fusion/core/nl.dbpedia.org/<http://downloads.dbpedia.org/databus/fusion/core/nl.dbpedia.org/>

(Note that the file and folder structure are still subject to change)
