OWLED 2014 - DEADLINE APPROACHING: JUL 30TH
APOLOGIES FOR MULTIPLE POSTINGS 11th OWL: Experiences and Directions Workshop (OWLED) Riva del Garda, October 17th - 18th, 2014 co-located with ISWC 2014 http://www.w3.org/community/owled/workshop-2014/ DEADLINE APPROACHING! Important Dates (All deadlines are Hawaii time) • Paper submission due: July 30, 2014 • Acceptance notifications: September 5, 2014 • Final papers due: September 18, 2014 • OWLED workshop: 17-18 October, 2014 OWLED is now also a Community Group at the W3C. Everyone is invited to participate:http://www.w3.org/community/owled/ —— The aim of the OWL: Experiences and Directions Workshop (OWLED) is to establish an international forum for the OWL community, where practitioners in industry and academia, tool developers and others interested in OWL can describe real and potential applications, share experience and discuss requirements for language extensions/modifications. OWL has become the representational model of choice for supporting interoperability in many industries. This has been made possible thanks also to the development of numerous OWL reasoning systems that efficiently deal with both intensional (ontologies) and extensional (data) query answering. In this edition we aim to bridge the gap with the reasoner evaluation community and welcome the submission of papers describing challenging ontologies and/or tasks to be represented in OWL and processed by OWL reasoners. It also welcomes proposals for improving the OWL 2 standard. This year, we would like to invite submissions of the following types of papers: Technical papers: All submissions must be in English and be no longer than 12 pages (including references). Papers that exceed this limit will be rejected without review. These papers should present research, implementation experience, and reports on the above and related topics. Space will be reserved for authors to present their work at the workshop. Short papers (4-6 pages, including references): These papers should present work that is in an early stage and/or include publishable (novel) implemented systems that are of interest to the OWLED community; and (in case of an implemented system), can be demonstrated at the workshop. All submissions must be must be in PDF, and must adhere to the Springer LNCS style. For more details, see Springer’s Author Instructions: http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0. Papers can be submitted online using the Easychair Conference system: https://www.easychair.org/conferences/?conf=owled2014 Papers related to any aspects of OWL and extensions, applications, theory, methods and tools, are welcome. Topics of interest include, but are not limited to: • Application driven requirements for OWL • Applications of OWL, particularly • from industry or • for data integration • for service interoperability • for sophisticated/non-obvious inference • for knowledge discovery • and within specific domains such as • law • bio and biomed • eLearning • Experience of using OWL: notably, highly expressive ontologies or the OWL 2 Profiles • Evaluation of OWL tools e.g. reasoners • Benchmarks for OWL tools • Performance and scalability issues and improvements • Extensions to OWL • OWL and Rules • Implementation techniques and experience reports • Non-standard reasoning service (implementation and requirements for) • Explanation • Ontology comprehension and verbalisation • Multilingual OWL • Modelling issues • Tools, including editors, visualisation, parsers and syntax checkers • Collaborative editing of ontologies • Versioning of OWL ontologies • Alignment of OWL ontologies • Modularity • Query answering with OWL • SPARQL and OWL • Linked Data and OWL ___ Dr Valentina Tamma Department of Computer Science| http://www.csc.liv.ac.uk/~valli University of Liverpool | tel. +44-151-795 4246 Ashton Building| fax +44-151-795 4235 Liverpool, L69 3BX, UK| email: v.ta...@liverpool.ac.uk | skype: valentinatamma
Updated LOD Cloud Diagram - Please enter your linked datasets into the datahub.io catalog for inclusion.
Hi all, Max Schmachtenberg, Heiko Paulheim and I have crawled of the Web of Linked Data and have drawn an updated LOD Cloud diagram based on the results of the crawl. This diagram showing all linked datasets that our crawler managed to discover in April 2014 is found here: http://data.dws.informatik.uni-mannheim.de/lodcloud/2014/ISWC-RDB/LODCloudDi agram.png We also analyzed the compliance of the different datasets with the Linked Data best practices and a paper presenting the results of the analysis is found below. The paper will appear at ISWC 2014 in the Replication, Benchmark, Data and Software Track. http://dws.informatik.uni-mannheim.de/fileadmin/lehrstuehle/ki/pub/Schmachte nbergBizerPaulheim-AdoptionOfLinkedDataBestPractices.pdf The raw data used for our analysis is found on this page: http://data.dws.informatik.uni-mannheim.de/lodcloud/2014/ISWC-RDB/ Our crawler did discover 77 dataset that do not allow crawling via their robots.txt files and these datasets were not included into our analysis and are also not included in the current version of the LOD Cloud diagram. A list of these datasets is found at http://data.dws.informatik.uni-mannheim.de/lodcloud/2014/ISWC-RDB/tables/not CrawlableDatasets.tsv In order to give a comprehensive overview of all Linked Data sets that are currently online, we would like to draw another version of the LOD Cloud diagram including the datasets that our crawler has missed as well as the datasets that do not allow crawling. Thus, if you publish or know about linked datasets that are not in the diagram or in the list of not crawlable datasets yet, please: 1. Enter them into the datahub.io data catalog until August 8th. 2. Tag them in the catalog with the tag lod (http://datahub.io/dataset?tags=lod) 3. Send an email to Max and Chris pointing us at the entry in the catalog. We will include all datasets into the updated version of the cloud diagram, that fulfill the following requirements: 1. Data items are accessible via dereferencable URIs. 2. The dataset sets at least 50 RDF links pointing at other datasets or at least one other dataset is setting 50 RDF links pointing at your dataset. Instructions on how to describe your dataset in the catalog are found here: https://www.w3.org/wiki/TaskForces/CommunityProjects/LinkingOpenData/DataSet s/CKANmetainformation Please make sure that you include information about the RDF links pointing from your dataset into other datasets (field links: ) as well as a tag indicating the topical category of your dataset, so that we know how to include it into the diagram. Please also include an example URI from your dataset into the catalog. We will start to review the new datasets and to draw the updated version of the LOD cloud diagram after August 8th.

final CFP: EMNLP workshop on Taxonomy Extraction with Applications in Semantics (TEXAS)
Taxonomy Extraction with Applications in Semantics (TEXAS) http://emnlp2014.org/workshops/TEXAS/call.html At EMNLP 2014, 29 October 2014, Doha, Qatar ** Submission deadline: July 26, 2014 ** Taxonomies form the backbone of knowledge-based systems by organizing knowledge in a machine interpretable manner and facilitating information integration. Hierarchical structures provide valuable input in knowledge-intensive applications such as question answering and textual entailment and are useful tools for browsing and navigation of document collections, especially when applied for exploration and discovery. The TEXAS workshop aims to provide a venue for presenting and discussing approaches that evaluate taxonomy extraction, and its subtasks (term/concept extraction, term/concept relation discovery, taxonomy construction and cleaning) in the context of semantic applications such as: entity search, entity disambiguation and linking, information integration and summarization, knowledge acquisition, knowledge sharing, inference in NLP tasks (question answering, textual entailment), etc. In this way, progress towards automatically constructed hierarchies can be measured relative to other tasks and real-world applications. Expected research topics of relevance to the workshop: * application-based evaluation of taxonomies in question answering, document browsing,document clustering, expert finding or other applications; * using automatically constructed taxonomies for searching, browsing and organizing information * constructing taxonomies for/from social media * probabilistic models for topic hierarchies (hierarchical topic modelling) * constructing taxonomies using hierarchical clustering * using distributional models for taxonomy construction * acquisition and modelling of categorical structure and modelling human category acquisition * constructing topic categorization systems and subject hierarchies * constructing hierarchical faceted metadata structures * methods for transforming semi-structured knowledge resources into taxonomies * merging and aligning existing resources for taxonomy construction * comparing, aligning and evaluating existing hierarchical structures * domain glossary acquisition and extracting taxonomies from definitions * constructing application/domain specific taxonomies from existing resources (lexical resources,Linked Open Data, Wikipedia category structure, semantic networks) * using different hierarchical structures (e.g., tree, DAG) and relation types (e.g., hyponymy, meronymy) for taxonomy construction * attaching Named Entities to hierarchical structures and using Named Entities to drive taxonomy construction by extensional analysis * multilinguality and taxonomies: constructing and using multilingual taxonomies Paper Submissions Submissions should be made electronically, using Softconf at https://www.softconf.com/emnlp2014/texas2014/. Submissions should follow the two-column format of ACL 2014 proceedings and should not exceed 8 pages of content and one additional references page. The LaTeX style files and the Microsoft Word style files tailored for this year's conference are available at: http://emnlp2014.org/call.html. The reviewing of papers will be double-blind, so please make sure your paper shows the title, but no author information. You should likewise not have any self identifying references anywhere in the paper submitted for review. For example, rather than this: We showed previously (Smith, 2001), ..., use citations such as: Smith (2001) previously showed . References to your own work in thesis proposals should also be anonymized. You may for example write it as in X (2000) we showed, etc. and do not add your papers in the reference list.

Dear Colleagues,
OGC started a Temporal Domain Working Group last year
to address a number of problems in the geospatial domain. In
particular, that time is usually just viewed as Yet Another
Attribute of Features, rather than a first class
coordinate.
We agreed earlier this year, in Geneva, that the OGC
Naming Authority would have a branch to register Temporal,
and index based, Coordinate Reference Systems, and we agreed
on the fundamental attributes that a CRS should have to be
registered.
We hope to produce a Best Practice document this year
to help clarify many confusions between CRSs, notations,
calendars, operations and calculations. I think that now we
have a good enough understanding of the underlying
conceptual issues and current
geospatial standards.
We have been accumulating info on an open wiki
http://external.opengeospatial.org/twiki_public/TemporalDWG/WebHome
and discussing via our
mailing list, though we are not very disciplined about
it.
One concern that I have is that we do not re-invent the
wheel, and do nugatory work, hence this email. I do not
envisage that we will need to do much with Calendars, which
have been covered so well by Dershowitz and Reingold.

Re: Updated LOD Cloud Diagram - Please enter your linked datasets into the datahub.io catalog for inclusion.
Dear Chris, Max Schmachtenberg, Heiko Paulheim and I have crawled of the Web of Linked Data and have drawn an updated LOD Cloud diagram based on the results of the crawl. That's awesome, thanks a lot! Would there be an SVG version at some point? I heard that at some point, people were working on a continuously updating version. I.e., a constraint solver that would generate it more or less automatically, so that new versions would be less of a pain in the future. Would that still be the case? What's the burden of releasing a next version? Best, Ruben

Re: Updated LOD Cloud Diagram - Please enter your linked datasets into the datahub.io catalog for inclusion.
Max, Heiko, and Chris, thank you for this very valuable work research that you do. Thousands (arguably millions) benefit from your high quality work. It is very much appreciated. I think the existence of LOD Cloud, how datasets are added, the analysis and your peer reviewed work should be included in a talk at SemTech 2014 in San Jose - the 10th anniversary of this conference. [1] This event has brought together thousands of sem tech advocates, pioneers practioners. FWIW, a number of us on this list are attending/speaking and exhibiting -- perhaps we can assist to make this happen? What do you think? I'm happy to help. Alternatively, please consider at least doing an interview with staff at semanticweb.com which has a wide audience. IMO, there is a lot of interest in the macro trends of publishing consuming LOD. Your work would help to counter the frustrating comments I still hear from people who learned about the semantic web 8 years ago but haven't kept up. Normally I wouldn't care about someone ill-informed saying, 'the semantic web has gone no where -- after a decade, no one is using it ...' However, I recently heard those words uttered by someone who worked at a major search firm (formerly), has a prestigious title at a public policy think tank and was sitting at a breakout session with CTO's from US Census the National Oceanic and Atmospheric Administration (NOAA) at the White House! Surely the world benefits if data rich authorities know about why being part of the LOD Cloud is a good thing. Note: This speaker's comments were dismissed by the CIOs an exec from PricewaterhouseCoopers (go figure!) but nonetheless Linked Data PR needs some improving your paper supporting graphs are a valuable contribution. Again, thank you I hope you'll consider providing some input (slides, whatever) to a talk at Semtech '14 to advance the cause.

A list of these datasets is found at http://data.dws.informatik.uni-mannheim.de/lodcloud/2014/ISWC-RDB/tables/notCrawlableDatasets.tsv In order to give a comprehensive overview of all Linked Data sets that are currently online, we would like to draw another version of the LOD Cloud diagram including the datasets that our crawler has missed as well as the datasets that do not allow crawling. Thus, if you publish or know about linked datasets that are not in the diagram or in the list of not crawlable datasets yet, please: 1. Enter them into the datahub.io data catalog until August 8th. 2. Tag them in the catalog with the tag ‘lod’ (http://datahub.io/dataset?tags=lod) 3. Send an email to Max and Chris pointing us at the entry in the catalog. We will include all datasets into the updated version of the cloud diagram, that fulfill the following requirements: 1. Data items are accessible via dereferencable URIs. 2. The dataset sets at least 50 RDF links pointing at other datasets or at least one other dataset is setting 50 RDF links pointing at your dataset. Instructions on how to describe your dataset in the catalog are found here: https://www.w3.org/wiki/TaskForces/CommunityProjects/LinkingOpenData/DataSets/CKANmetainformation Please make sure that you include information about the RDF links pointing from your dataset into other datasets (field links: ) as well as a tag indicating the topical category of your dataset, so that we know how to include it into the diagram. Please also include an example URI from your dataset into the catalog. We will start to review the new datasets and to draw the updated version of the
Read-Write Linked Open Data via WebID, LDP, and WAC
All, I would like to share my euphoria with everyone, following successful interoperability tests based on the following open standards (actual, de facto, or works in progress): 1. WebID -- HTTP URI for Agent (People, Organizations, Software, Machines) Denotation 2. WebID-Profile -- Agent Description (basically WebID referent connotation) 3. WebID-TLS -- Agent Identity Claims verification 4. WAC -- Web Access Controls applied to Authenticated WebIDs accessing protected resources 5. Linked Data Platform (LDP) -- HTTP interactions for Read-Write oriented operations against Linked Open Data Spaces (Personal or Enterprise) comprised of protected and unprotected resources 6. X.509 -- Digital Identity Card (Certificate) representation for use in local keystores and keychains 7. PKI -- in regards to Public Private key based asymmetric encryption. I've just published a blog post [1] that walks you through my interoperability exercise that results in the successful use of CIMBA (deployed by two distinct LDP platforms) to post actual microblog data to Dropbox (note: the very same exercise works with similar storage providers such as Google Drive, Microsoft OneDrive, Amazon S3, Box., etc.). What makes the storage providers important, in this context? They are cloud hosted hard disks that offer generous amounts of storage for RDF documents. Net effect, storage capacity and HTTP server configuration complexity are no longer hurdles to Linked Open Data publication and/or creation. You can use the time-test file create, save, and share pattern to make statements about anything, whenever, from wherever. All of that without utterly compromising your personal privacy since you have full control over: 1. Identifiers that denote You 2. Identity Cards that Describe You 3. Location of paired public and private Identity Cards that Describe You 4. Signature(s) used to verify claims made by You 5. Key used to encrypt data that's are managed by You.

Re: Updated LOD Cloud Diagram - Please enter your linked datasets into the datahub.io catalog for inclusion.
Hi, On 07/25/2014 12:39 AM, Mike Liebhold wrote: I recall earlier versions of the LOD Cloud diagram included freebase - I don't see it here, - or the google knowledge graph either. am I missing something? it might be because of bugs in their Linked Data API. I've sent a mail on freebase-discuss to let them know. Cheers, Andreas.
