Hi,

I am a PhD at Aalborg University currently working on setting up a Lucene
model to be used as a keyword search endpoint for a set of entity linkers I
am evaluating.
I am currently struggling with getting the same keyword search performance
compared to DBpedia Spotlight.
Can you tell me about the the configuration of Lucene in DBpedia Spotlight,
such as which fields you build and what data it contains, as well as how
you construct queries given a keyword query for candidate generation?

Thanks

[Dbp-spotlight-developers] Limit of DBPediaSpotlight

[Florent G. <ghi...@gm...>]

Hello,
i'm actually testing DBPediaSpotlight, the project is really awesome but
i'm asking myself about the following example:

in the demo i used the text:
"Watson is a question-answering computer system capable of answering
questions posed in natural language,[2] developed in IBM's DeepQA project
by a research team led by principal investigator David Ferrucci.[3] Watson
was named after IBM's first CEO, industrialist Thomas J. Watson.[4][5]
The computer system was initially developed to answer questions on the quiz
show Jeopardy![6] and, in 2011, the Watson computer system competed on
Jeopardy! against legendary champions Brad Rutter and Ken Jennings[4][7]
winning the first place prize of $1 million.[8]
In February 2013, IBM announced that Watson software system's first
commercial application would be for utilization management decisions in
lung cancer treatment at Memorial Sloan Kettering Cancer Center, New York
City, in conjunction with health insurance company WellPoint.[9] IBM
Watson's former business chief, Manoj Saxena, says that 90% of nurses in
the field who use Watson now follow its guidance.[10]"

the wikipedia page of "Watson (computer)". But despite this, "Watson"
entity is still wrong tagged and "Watson (computer)" is far away in the
list of candidates.. (only showed with confidence of 0)

Is there something wrong somewhere ? DBPedia is not checking in the whole
text context ?

Thanks for advises

Florent

[Dbp-spotlight-developers] DBpedia API documentation and uptime monitor

[Sandro C. <san...@gm...>]

Hello everyone,



As a result of our last DBpedia DEV meeting, let’s keep track of what we
already have done.



DBpedia SWAGGER API:



We have started to document all DBpedia services at Swagger HUB (
https://app.swaggerhub.com/search?type=API&owner=DBpedia). Swagger HUB is a
platform where we can keep tracking our services throughout our development
lifecycle. It provides facilities such as versioning and collaborative
editing, among others that fit well for our community.



It is also possible to bring this documentation on our project pages using
swagger-ui <http://swagger.io/swagger-ui/>, loading JSON or YAML
definitions straight from the swagger hub
<http://swagger.io/integrating-with-the-swaggerhub-api/>. You can see an
example of how it works here: http://www.dbpedia-spotlight.org/api



DBpedia Service Mapping and Uptime Monitoring:



The DBpedia Association has started a survey to map all services provided
by the DBpedia Community. Our objectives are improving our support and go
further with best practices in governance. As a result, we will update
language chapter page (http://wiki.dbpedia.org/about/language-chapters) and
keep tracking our service availability under
https://stats.uptimerobot.com/J81Ppcl2k , later http://status.dbpedia.org
(not working yet).

If you require any further information, feel free to contact me via slack
or email.


All the best,

Sandro

[Dbp-spotlight-developers] DBpedia support, mailing lists and newsletter

[Sebastian H. <pr...@in...>]

Dear fellow DBpedians,

We are currently trying to streamline community communications due to 
the immense growth we had over the last years. The first change is that 
we have updated the Get Involved page to server as a central point of 
reference for everybody: http://wiki.dbpedia.org/get-involved
Any feedback is of course welcome. We are still working on many 
remaining pages of the website, next one will be a proper 
acknowledgements page for the community.

Furthermore, we made the following changes:


      # Support

There is a support channel now:
http://wiki.dbpedia.org/support
backed by an Atlassian Q&A: https://dbpedia.atlassian.net/wiki/questions

We would kindly ask you to sign up and help us answer some questions. 
Good answers will be tracked and add to the reputation of the user.


      # Mailing lists

We are currently having 4 main mailing lists: DBpedia Discussion, 
Developers, Spotlight Users and Developers
One of the main reasons to establish the DBpedia developers list was 
that the Discussion list was too full of call for papers and support 
questions. We made a survey a while ago and there was agreement that 
there should only be announcements which are directly relevant to 
DBpedia, so we are currently following this strategy:
## DBpedia Discussion list:
* "Only Call for Papers relevant to DBpedia" strictly enforced
* Support questions moved to the portal
* Mappings Wiki signup moved to 
https://dbpedia.atlassian.net/wiki/questions/3145735/what-is-your-dbpedia-mappings-wiki-account-name
## DBpedia Developer list:
* merge with Discussion or Slack http://dbpedia.slack.com/
## Spotlight lists
* no clear policy yet, as we are missing feedback, but some discussion 
is also on http://dbpedia.slack.com/


      # Newsletter

please find below the first edition of the DBpedia Newsletter, which 
will be sent to all subscribers (~1900) in a three month interval. Of 
course, we would welcome any people who are interested to sign up 
(http://eepurl.com/crrrkz). We are collecting info from the discussion 
list, but also allow DBpedians to include news in our newsletter. (Text 
with links and less than 100 words to db...@in...)

Thank you very much for your attention,
Sebastian


    *(Belated) Happy New Year to all DBpedians!*

We are a proud to look retrospectively at a successful year 2016 and 
would like to welcome 2017 with our new newsletter (~4 times per year), 
which will allow you to stay up to date and provide feedback, e.g. via 
the included survey and the planned events in 2017.

*New members *- We kickstarted 
the<http://wiki.dbpedia.org/dbpedia-association>_DBpedia Association_ 
<http://wiki.dbpedia.org/dbpedia-association> with a first wave of new 
members: OpenLink Software, Semantic Web Company, Ontotext, FIZ 
Karlsruhe, Mannheim University, Poznań University of Economics and 
Business, the Business Information Systems Institute Ltd and the Open 
Knowledge Foundation Greece joined the DBpedia Association in 2016. We 
created two web pages that summarize reasons 
to<http://wiki.dbpedia.org/why-is-dbpedia-so-important>_support DBpedia 
via donations_ <http://wiki.dbpedia.org/why-is-dbpedia-so-important> 
and<http://wiki.dbpedia.org/membership>_become a member_ 
<http://wiki.dbpedia.org/membership>.

*DBpedia in Dutch* (_http://nl.dbpedia.org_ <http://nl.dbpedia.org/>) is 
the first chapter which formalized an official DBpedia Chapter 
consortium. The cooperation was initiated by Koninklijke Bibliotheek 
(National Library of the Netherlands) and Huygens ING (research 
institute of History and Culture). Other partners like imec/Ghent 
University, the Netherlands Institute of Sound and Vision and the 
Network Institute (Vrije Universiteit) joined as well. This cooperation 
will strengthen the DBpedia Dutch chapter and community of contributors 
as well improve the cooperation with the Dutch research infrastructure 
and the Dutch Digital Heritage.

We are in intensive contact with the Japanese, the German and the 
Italian chapters to form official chapters and gain institutional 
support for DBpedia. You would like to know how to start a DBpedia 
chapter? Please check 
here:<http://wiki.dbpedia.org/about/language-chapters>_http://wiki.dbpedia.org/about/language-chapters_

*DBpedia Releases *- Since 2015 we provide bi-annual DBpedia releases. 
The latest 
one,<http://wiki.dbpedia.org/dbpedia-version-2016-04>_2016-04_ 
<http://wiki.dbpedia.org/dbpedia-version-2016-04>, featured a new 
Wikipedia references & citation dataset for the English Wikipedia. In 
addition, we separated the data which we received from heuristic-based 
infobox extractors from the already mapped and quality-controlled data 
to remove low quality data and avoid duplicates & low quality 
information. We improved on 
our<http://www.semantic-web-journal.net/content/wikidata-through-eyes-dbpedia-1>_Wikidata 
extraction_ 
<http://www.semantic-web-journal.net/content/wikidata-through-eyes-dbpedia-1> 
and mapped all our data to Wikidata-based DBpedia IRIs. Wikidata will 
become more and more the core of future extractions.

*Consortium partners for EU and national projects - *Since its 
conception DBpedia has never been funded directly, but was supported 
only by individual tasks in different projects and by the spirit of 
volunteers. With the establishment of the DBpedia Association, we are 
now in a position to receive direct funding and are eligible as a full 
consortium partner for EU and International projects. Furthermore, we 
are able to mediate trusted partners - who have worked with us in the 
past and contributed greatly to DBpedia - for national proposals in over 
30 countries worldwide (contact via reply to this email.)

*Events - *In addition to our participation in the 12th edition of the 
SEMANTiCS, in the 19th International Conference on Business Information 
Systems and in the Google Summer of Code project, we arranged three 
DBpedia community meetings, in The Hague, Leipzig and Sunnyvale, 
California. In order to get updates on our events and projects, stay 
tuned and check the<http://blog.dbpedia.org/>_DBpedia blog_ 
<http://blog.dbpedia.org/>. Please check out the dates to the two new 
DBpedia meetings below.

*Links - *We have revived the portal, that allows the LOD community to 
contribute their links, so we can include them in DBpedia Releases. If 
your database links to DBpedia, you can submit your links 
here:<https://github.com/dbpedia/links>_https://github.com/dbpedia/links_ 
. We provide additional support for this and also provide a service, 
that - once you have contributed your links - will tell you which data 
is linking to your knowledge base via 
DBpedia<http://downloads.dbpedia.org/links/backlinks/>_http://downloads.dbpedia.org/links/backlinks/_, 
available only for Association members.

/We would like to thank again all people who were involved to enable this!/


    *2017 - New Year - New Opportunities*

To make 2017 as great as 2016 we have already reviewed community 
feedback and worked out some plans to bring the DBpedia community closer 
together whereas we attain our goals and follow our visions. Below are 
the most important points for 2017.

*User Survey - *Sören Auer and the DBpedia Board prepared a survey to 
assess the direction of DBpedia and the DBpedia Association. We would 
like to know what you think should be our priorities. Please take a 
minute and vote 
here:<https://goo.gl/forms/NQxrMWskcKlZJAU63>_https://goo.gl/forms/NQxrMWskcKlZJAU63_

*User support *- We set up a new portal to streamline support requests 
for DBpedia. We would encourage you to submit all questions 
to<http://wiki.dbpedia.org/support>_http://wiki.dbpedia.org/support_.

And … if you are already an experienced DBpedia user, you can sign up 
and answer questions and get kudos. Upon request, we can issue a 
certificate for your CV. During the course of 2017 we will also provide 
a priority support channel for members and Chapters.

*Save the Date* *- Galway 21 Jun and Amsterdam 14 Sep*. DBpedia will be 
part of the_Language, Data and Knowledge (LDK) conference_ 
<http://ldk2017.org/> in Galway, Ireland (*Submission open until Feb 
16th*). This new biennial conference series aims at bringing together 
researchers from across disciplines. The DBpedia community will have a 
full day event on 21th of June 2017. Also during 
the<http://2017.semantics.cc/>_SEMANTiCS 2017 in Amsterdam_ 
<http://2017.semantics.cc/>, Sep 11-14 (*Submission open until May 17th 
or June 23rd*), the DBpedia community will get together on the 14th of 
September for a DBpedia community meeting. Updates will be posted in the 
respective<http://wiki.dbpedia.org/events>_events section_ 
<http://wiki.dbpedia.org/events> and the<http://blog.dbpedia.org/>_blog_ 
<http://blog.dbpedia.org/>.

*TextExt: DBpedia’s Open Text Extraction Challenge -* 
(_http://wiki.dbpedia.org/textext_) As DBpedia and Wikidata currently 
focus primarily on representing factual knowledge as contained in 
Wikipedia infoboxes, we created the DBpedia Open Text Extraction 
Challenge. Participants are asked to submit their engines that extract 
facts and knowledge from Wikipedia article texts to dramatically broaden 
and deepen the amount of structured DBpedia/Wikipedia data.

*Community coordination* - *You'd like to get involved in DBpedia? *We 
set up a new Get Involved section. If you are interested in details or 
would like to get in touch with the DBpedia community, please read 
here:<http://wiki.dbpedia.org/get-involved>_http://wiki.dbpedia.org/get-involved_

*Community chairs *- The active community of developers and engineers 
comes together in the DBpedia community committee. We will build up this 
committee with the help of Pablo Mendes and Magnus Knuth who will serve 
as provisional chairs. The committee can be joined by recommendation 
only based on merit. If you would like to get in contact with the 
community committee please check 
here:<http://wiki.dbpedia.org/about/contact>_http://wiki.dbpedia.org/about/contact_

Two delegates from the community committee are elected chairs and will 
take seats at the Board of Trustees. This board is the main 
decision-making body of the DBpedia Association and oversees the 
association and its work, as its ultimate corporate authority. There are 
four board meetings per year, please have a look at the public minutes 
here:<http://wiki.dbpedia.org/board-minutes>_http://wiki.dbpedia.org/board-minutes_

*Technical development I: Wikidata - *Many DBpedians are excited about 
the progress<https://www.wikidata.org/>_Wikidata_ 
<https://www.wikidata.org/> is making and we are planning to use 
Wikidata’s data as the new core for our extraction and fusion. This 
means that in future releases we will fuse data from Wikidata with the 
usual data we extract from over 100 Wikipedia language editions with 
additional data from other high quality LOD sources and do the usual 
refinement, typing and quality-control. We hope that this will provide 
an unprecedented knowledge graph with superior coverage, completeness 
and correctness.

*Technical development II: UnifiedViews - *our plan to achieve the above 
mentioned fusion will be realized by an active collaboration with 
the<https://www.semantic-web.at/>_Semantic Web Company (SWC)_ 
<https://www.semantic-web.at/>, where DBpedia developers work side by 
side with the<http://www.poolparty.biz/>_PoolParty Semantic Suite_ 
<http://www.poolparty.biz/> technical team to add scalability, 
provenance tracking and linking/fusion capabilities into the Data 
Processing Units of 
the<https://www.poolparty.biz/unifiedviews/>_UnifiedViews_ 
<https://www.poolparty.biz/unifiedviews/> workflows.

*Technical development III - *For 2017, we hope to establish further 
hands-on collaboration with companies and organisations to push all 
aspects of DBpedia, in particular: search and visualisation, ontology 
maintenance, querying and indexing crawling data from web and social 
media. We also work together with our members to prioritize on 
integrating data that they think useful.

*Membership* - If you would like to become a member of the DBpedia 
Association, please check all benefits 
here:<http://wiki.dbpedia.org/membership>_http://wiki.dbpedia.org/membership_.

If you require any further information, feel free to contact us by 
replying to this email. We are already very excited to spend time with 
you on further community meetings and to publish new DBpedia releases.

All the best,

Julia, Dimitris & Sebastian

[Dbp-spotlight-developers] DBpedia Open Text Extraction Challenge - TextExt

[Sebastian H. <hel...@in...>]

*DBpedia Open Text Extraction Challenge - TextExt*

Website: http://wiki.dbpedia.org/textext

*_Disclaimer: The call is under constant development, please refer to 
the news section. We also acknowledge the initial engineering effort and 
will be lenient on technical requirements for the first submissions and 
will focus evaluation on the extracted triples and allow late 
submissions, if they are coordinated with us_*.


      Background

DBpedia and Wikidata currently focus primarily on representing factual 
knowledge as contained in Wikipedia infoboxes. A vast amount of 
information, however, is contained in the unstructured Wikipedia article 
texts. With the DBpedia Open Text Extraction Challenge, we aim to spur 
knowledge extraction from Wikipedia article texts in order to 
dramatically broaden and deepen the amount of structured 
DBpedia/Wikipedia data and provide a platform for benchmarking various 
extraction tools.


      Mission

Wikipedia has become the ubiquitous source of knowledge for the world 
enabling humans to lookup definitions, quickly become familiar with new 
topics, read up background infos for news event and many more - even 
settling coffee house arguments via a quick mobile research. The mission 
of DBpedia in general is to harvest Wikipedia’s knowledge, refine and 
structure it and then disseminate it on the web - in a free and open 
manner - for IT users and businesses.

    SEMANTiCS <http://2017.semantics.cc/> joined the challenge (Deadline
    June 11th and July 17th)

  *

    Feb 20th, 2017: Full example added to this website

  *

    March 1st, 2017: Docker image (beta)
    https://github.com/NLP2RDF/DBpediaOpenDBpediaTextExtractionChallenge

Coming soon:

  *

    beginning of March: full example within the docker image

  *

    beginning of March: DBpedia full article text and tables (currently
    only abstracts) http://downloads.dbpedia.org/2016-10/core-i18n/


      Methodology

The DBpedia Open Text Extraction Challenge differs significantly from 
other challenges in the language technology and other areas in that it 
is not a one time call, but a continuous growing and expanding challenge 
with the focus to *sustainably* advance the state of the art and 
transcend boundaries in a *systematic* way. The DBpedia Association and 
the people behind this challenge are committed to provide the necessary 
infrastructure and drive the challenge for an indefinite time as well as 
potentially extend the challenge beyond Wikipedia.

We provide the extracted and cleaned full text for all Wikipedia 
articles from 9 different languages in regular intervals for download 
and as Docker in the machine readable NIF-RDF 
<http://persistence.uni-leipzig.org/nlp2rdf/> format (Example for 
Barrack Obama in English 
<https://github.com/NLP2RDF/DBpediaOpenDBpediaTextExtractionChallenge/blob/master/BO.ttl>). 
Challenge participants are asked to wrap their NLP and extraction 
engines in Docker images and submit them to us. We will run 
participants’ tools in regular intervals in order to extract:

 1.

    Facts, relations, events, terminology, ontologies as RDF triples
    (Triple track)

 2.

    Useful NLP annotations such as pos-tags, dependencies, co-reference
    (Annotation track)

We allow submissions 2 months prior to selected conferences (currently 
_http://ldk2017.org/_ and _http://2017.semantics.cc/_ ). Participants 
that fulfil the technical requirements and provide a sufficient 
description will be able to present at the conference and be included in 
the yearly proceedings. *Each conference, the challenge committee will 
select a winner among challenge participants, which will receive 1000€. *


      Results

Every December, we will publish a summary article and proceedings of 
participants’ submissions at _http://ceur-ws.org/_ . The first 
proceedings are planned to be published in Dec 2017. We will try to 
briefly summarize any intermediate progress online in this section.


      Acknowledgements

We would like to thank the Computer Center of Leipzig University to give 
us access to their 6TB RAM server Sirius to run all extraction tools.

The project was created with the support of the H2020 EU project HOBBIT 
<https://project-hobbit.eu/> (GA-688227) and ALIGNED 
<http://aligned-project.eu/> (GA-644055) as well as the BMWi project 
Smart Data Web <http://smartdataweb.de/> (GA-01MD15010B).

We will back to release our models monthly soon , but I have checked that
our code is 100% compliance with 2016-04 dumps.

[Dbp-spotlight-developers] Call for GSoC 2017 project ideas and GSoC mentors

[Dimitris K. <kon...@in...>]

Hello everyone,

As previous years, we would like your input for DBpedia related project
ideas for GSoC 2017.

For those unfamiliar with GSoC (Google Summer of Code), Google pays
students (BSc, MSc, PhD) to work for 3 months on an open source project.
Open source orgs announce their student projects and students apply for
projects they like. After a selection phase, students are matched with a
specific project and a set of mentors to work on the project during the
summer.

see https://developers.google.com/open-source/gsoc/
or http://wiki.dbpedia.org/gsoc2016

If you have a cool idea for DBpedia or want to co-mentor an existing cool
idea go here (All mentors get a free Google Tshirt and get the chance to go
Google HQs in November)
https://docs.google.com/document/d/19_6ZIA9dM4bhMFx06a393zeEimJQ3NNVOEPnzAwed7o/edit#

Looking forward to your input

Dimitris

Re: [Dbp-spotlight-developers] Average runtime estimation

[Sandro C. <san...@gm...>]

Hi Marcelo,

We don't have these benchmarks.

As a developer, you can start configuring JVM memory parameters and test it
using load tests (You can use a tool like JMeter, for example).

[Dbp-spotlight-developers] Average runtime estimation

[Marcelo M. <mar...@gm...>]

Dear all,

Has anyone made an estimate about the average runtime to annotate with
Lucene? Something like time/words, pointing the language model. And if so,
I would like to know what are best practices, as a developer,  to come up
with a better time.

Best regards,

[Dbp-spotlight-developers] DBpedia Spotlight - New server

[Sandro C. <san...@gm...>]

Dear all,

We are proud to announce that the DBpedia Spotlight has a new home at RNP /
UFJF in Brazil. All endpoints have been migrated, and the service is
already available <http://dbpedia-spotlight.github.io/demo>.

We would like to say a big thank you to everyone that are collaborating
with the project, especially the MTA Sztaki Team that was hosting our old
production server for the internationalized statistical backend.

Best regards,

DBpedia Spotlight Team.

[Dbp-spotlight-developers] Summary of Association Hour in Leipzig

[Sebastian H. <hel...@in...>]

Dear all,

thank you for the very constructive meeting we had in Leipzig. 
Personally, I was quite happy since we are moving from a loose and 
slow-moving community to a better-organised form with clear goals and 
vision and the actual capacity to make public data better! I tried to 
sum up the most important points below.

All the best,

Sebastian


# Membership benefits:

- currently the main benefit of becoming a member association is the 
community effect, i.e. the individual contributions add up and provide a 
better DBpedia overall, which could not have been achieved by 
individuals, thus providing a general benefit for everybody

- the question arose that there should be clearer message regarding 
incentive/advantages/benefits  for individual members, especially 
targeting industrial members. Several ideas were given and will be 
consolidated in a document.

# Next Language Chapters to join:

- Japanese Chapter
- Greek Chapter
- Spanish Chapter

# DBpedia Uptime:

- Option 1: increase funding for more powerful hosting of the main 
endpoint , a rough figure by OpenLink: 99.99% uptime would be around 
50k/year

- Option 2: Community crowd-sourcing, i.e. uptime can be improved when 
we take off the heaviest users. For example, packaging DBpedia in docker 
and offering an easy way for configuration should help potential 
exploiters to do it on their own infrastructure, thus freeing resources 
to incidental (and less skilled) users. First steps are to create a list 
of public DBpedia endpoints and an official tutorials on setting up a 
DBpedia mirror.

- Option 3: Freemium model: limit number of queries per IP 
(daily/monthly), which are offered for free. Additional queries require 
contract/subscription/contribution.

# Collaboration with WikiData

A major barrier to Wikidata using our data is that they do not contain 
any provenance information. WikiData will only accept data that has a 
reference, i.e. a clear source to where the claim is given outside of 
Wikipedia, as Wikipedia is only a collection of information itself, not 
a source. A clear action would be to extract more references from 
Wikipedia.


# Citation and reference session
  - Add links to original sources/research work. This can also be 
reflected in provenance.
- quite comprehensive work on the polish DBpedia, there will be a follow-up


# NLP & DBpedia session
- NE hot topic
- two presentation from GSoC
- research should focus on bigger problems

# Ontology Session
- task to research on extracting data with a difference scheme and see 
if inferencing is possible
- Monika will choose an upper ontology or schema.org, create mappings to dbo
- Dimitris will temporarily replace the mappings to the new ones and 
rerun extraction to get data with the new schema

Developer session
- overview about the dev process and the merging into the framework
- - DataID - Integration
- - RML- Integration



Other Actions:
- set up a task force for crowd-sourced coordinated hosting
- Soeren will prepare a survey to assess direction where we are going
- next meeting: application from Greece, Thessaloniki  in Spring
- add extraction framework to the discussion buckets
- provide checksum for file
- rethink bzip2 and switch to gzip

[Dbp-spotlight-developers] Data Quality Tutorial @ SEMANTiCS

[Dimitris K. <kon...@in...>]

Hello,

Since it might be of interest to the DBpedia-* lists, we are organizing a
Data Quality Tutorial as a SEMANTiCS 2016 satellite event.
http://2016.semantics.cc/satellite-events/data-quality-tutorial

The tutorial tries to cover a big range of data quality topics, industry
views on quality and recent research developments. We also present some of
the work that is deployed on DBpedia, e.g. Mappings Validation by Anastasia
Dimou

Attending the tutorial is *free of charge* as the tutorial is sponsored by
the ALIGNED project (http://www.aligned-project.eu) but you need to
register.
Registering for the main conference is of course optional, although highly
recommended.

Note that you can combine this tutorial with the DBpedia meeting (
wiki.dbpedia.org/meetings/Leipzig2016) as they are both co-located with
SEMANTiCS (http://2016.semantics.cc/)

Best regards,
Dimitris Kontokostas

[Dbp-spotlight-developers] Change confidence with Lucene

[Jorão J. <jor...@gm...>]

Hello everyone,

   I'm trying to change the Lucene confidence parameter to limit the scores
surfaceform, but I'm not having success. When I change the parameter and do
the tests, all results are the same, unchanged. Only brings the same
results with confidence 0.0, without making any limitation of the score.
   I think that Lucene has any standard source code that is not letting
make changes in this parameter or it uses another paramter to perform this
process. Does anyone have any idea that can help?

Thanks,

Jorão Junior

[Dbp-spotlight-developers] Annotation with Lucene for large texts

[Marcos V. <mar...@gm...>]

Hello everyone,
I'm finding problems running the Lucene for a slightly large text . The
Grizzly gives timeout . Is there any relationship? One idea would be to
increase the timeout Grizzly, does anyone know how ?

Still , with a 32G machine you can run the Lucene in memory? Passing the
parameter ' org.dbpedia.spotilight.index.loadToMemory ' to true and
allocating whole heap is also launching a memory overflow exception. What
is the amount of memory required for this purpose?

Thanks,
Marcos Ferreira

Why don't you have a look at the fact extractor?
https://github.com/dbpedia/fact-extractor
It's closely related to what you are thinking about, except the machine 
learning algorithm used (SVM).
Currently, it's a language and domain-specific implementation, i.e., 
Italian and football.
It would be nice to scale up to other languages.

Another project that has just started is:
https://github.com/dbpedia/topicmodel-extractor
based on
http://wiki.dbpedia.org/ideas/idea/192/combining-dbpedia-and-topic-modelling/

Hi Hari,

apologies for the late response, I was on holidays and trying to catch up
with my inbox since I returned

You are of course more than welcome to contribute to DBpedia :)
>From my understanding, are you interested in working directly  in DBpedia
spotlight (http://spotlight.dbpedia.org)?

Other than that, we are trying to fill our project ideas page (
http://wiki.dbpedia.org/ideas) but it is still in progress
and Marco & Axel in cc are also actively working in the area and could set
up a project with you

Cheers & welcome
Dimitris
