From martin.hepp at ebusiness-unibw.org Mon Jan 4 23:47:04 2010 From: martin.hepp at ebusiness-unibw.org (Martin Hepp (UniBW)) Date: Mon, 04 Jan 2010 23:47:04 +0100 Subject: [goodrelations] http://loc.openlinksw.com/sparql endpoint down for maintenance Message-ID: <4B426FE8.3080202@ebusiness-unibw.org> Dear all: The SPARQL endpoint http://loc.openlinksw.com/sparql that used to collate a huge amount of GoodRelations data is currently down for maintenance, according to OpenLink Software, who operates it. Accordingly, queries and applications against this endpoint don't work for the moment. This is also the reason why the GoodRelations statistics tool at http://goodrelations-stats.appspot.com/ reports invalid results for the past ten counts. I expect the endpoint to be back online in a week or so. In the meantime, you can use the alternative endpoint http://uriburner.com/sparql/ Note that that endpoint contains a smaller subset of GoodRelations data. If you want all GoodRelations data in one place, then you can fetch a list of RDF graphs via the PingTheSemanticWeb API (see http://pingthesemanticweb.com/about.php#4) and load all graphs into a repository of your choice.

The research has shifted from proofs of concept towards foundational research in large projects, commercially sold enterprise systems and real world use cases. Besides evaluations of such use cases, technical innovation and foundational research are still needed, as the large-scale application of semantic wikis has unveiled a number of research questions. The aim of this fifth SemWiki workshop is to exchange ideas, to discuss pressing research questions arising from practical usage of semantic wikis, and to explore integrations of wikis with other semantic web technologies. Topics ====== We address researchers working on (but not limited to): * Applications of semantic wikis in the fields of: - e-science and e-learning - software and knowledge engineering - enterprise workflows - knowledge management or personal knowledge management * Integration and reuse of semantic wikis or (semantic) wiki content: - integrations with other semantic applications and mashups - browsing and navigating - visualizing - editing linked open data - scaling wikis to the web - giving semantics to non-semantic wikis (e.g. Wikipedia) - reusing semantics gained from wikis (e.g. DBpedia) - interlinked and distributed semantic wikis - innovative plugins/extensions for existing systems (e.g. Semantic MediaWiki) * Human and social factors of semantic wikis: - usability studies - empirical studies - analyses of semantic wiki contributors and their contributions; - overcoming entrance barriers - giving incentives for contributing - connecting knowledge and social interaction - community building - from asynchronous interactions to real-time/multi-synchronous interactions in semantic wikis - privacy: permissions, trust, licensing, access control * Knowledge representation and reasoning in semantic wikis: - combining formal and informal knowledge - multimodal reasoning/strong reasoning support - transforming informal to formal knowledge - making formal knowledge accessible - on-line knowledge evaluation - coping with inconsistencies - change management, truth maintenance, versioning, and undoing semantic changes - utilizing emerging knowledge models - rapid prototyping of schema-driven applications - collaborative ontology engineering Organisation Committee ====================== * Christoph Lange, Jacobs University Bremen, Germany ch.lange at jacobs-university.de * Sebastian Schaffert, Salzburg Research, Austria sebastian.schaffert at salzburgresearch.at * Hala Skaf-Molli, INRIA-Nancy University, France skaf at loria.fr * Jochen Reutelsh?fer, University of W?rzburg, Germany reutelshoefer at informatik.uni-wuerzburg.de Programme Committee =================== # S?ren Auer, Universit?t Leipzig (DE) # David Aum?ller, Universit?t Leipzig (DE) # Joachim Baumeister, Universit?t W?rzburg (DE) # Tobias B?rger, STI Innsbruck (AT) # Am?lie Cordier, LIRIS, Universit? de Lyon (FR) # Bj?rn Decker, Fraunhofer IESE (DE) # Alicia D?az, La Plata University (AR) # Sebastian Dietzold, Universit?t Leipzig (DE) # Fred Dur?o, University of Aalborg (DK) # Michael Erdmann, Ontoprise (DE) # Fabian Gandon, INRIA - Edelweiss (FR) # Herman Geuvers, Radboud University Nijmegen (NL) # Tudor Groza, DERI (IE) # Siegfried Handschuh, DERI (IE) # Martin Hepp, UniBW M?nchen (DE) # Guoqian Jiang, Mayo Clinic (US) # Malte Kiesel, DFKI (DE) # Jakub Kotowski, University of Munich (DE) # Markus Kr?tzsch, AIFB Karlsruhe (DE) # Tobias Kuhn, Universit?t Z?rich (CH) # Thomas Kurz, Salzburg Research (AT) # Stefanie Lindstaedt, Know-Center Graz (AT) # Pascal Molli, Nancy University, INRIA (FR) # Christine M?ller, Jacobs University Bremen (DE) # Claudia M?ller-Birn, Carnegie Mellon University (US) # Grzegorz Nalepa, AGH University Krakow (PL) # Amedeo Napoli, CNRS, LORIA (FR) # Viktoria Pammer, Know-Center Graz (AT) # Alexandre Passant, DERI (IE) # Jean Rohmer, Thales (FR) # Marek Schmidt, Technical University of Brno (CZ) # Matthias Samwald, Semantic Web Company (AT) # Daniel Schwabe, University of Rio de Janeiro (BR) # Elena Simperl, STI Innsbruck (AT) # Rolf Sint, Salzburg Research (AT) # Katharina Siorpaes, STI Innsbruck (AT) # Harold Solbrig, Mayo Clinic (US) # Stephanie Stroka, Salzburg Research (AT) # Max V?lkel, FZI Karlsruhe (DE) # Friedel V?lker, European Regiowiki Society # Klara Weiand, University of Munich (DE) Submission and Proceedings ========================== We invite the following different kinds of contributions: * full research or application papers (15 pages) describing recent research outcomes, mature work, prototypes, applications, or methodologies; authors of accepted full papers will be able to present their work in a 15 minute talk at the workshop * short position papers (5-10 pages) describing early work and new ideas that are not yet fully worked out; authors of short papers will be able to present their work in a 5-10 minute lightning talk at the workshop * demo outlines (5 pages) describing the demonstration of a software prototype in the poster and demo session during the workshop * poster descriptions (2 pages) outlining a poster to be presented in the poster and demo session during the workshop * *wiki submissions*: A set of wiki pages explaining/demonstrating the addressed topic or presenting a system. A Confluence space (on this site) will be provided on request but also own wikis can be used. Additionally, we require such submissions to be exported to PDF or HTML. Primarily, the wiki space will be reviewed, but the export serves as a backup for the reviewing in case of technical problems and is used to verify that the submission complies to the guidelines, e.g., does not exceed the page limit of the respective type of contribution. Where the exported PDF or HTML is not comparable to LNCS (see below), we estimate 400 words per page. All submissions except Wiki submissions should be formatted according to the Springer Lecture Notes in Computer Science (LNCS) format. For complete details on this issue see Springer's Author Instructions: http://www.springer.com/computer/lncs?SGWID=0-164-2-72376-0 Papers will be submitted using the EasyChair system: http://www.easychair.org/conferences/?conf=semwiki2010 In addition to ordinary submissions, all attendees of the workshop are encouraged to informally present their work in an open space session during the workshop if they are not (yet) able to submit a description of their work or to also discuss more recent work that has been done after the submission deadline of the workshop. Important Dates =============== Paper Submission: 26th February 2010 Author Notification: 5th April 2010 Camera ready: 18th April 2010 Workshop: May 30 or May 31, 2010 In case of questions, feel free to contact any of the organisers: chair at semwiki.org -- Jochen Reutelsh?fer Department of Artificial Intelligence and Applied Informatics University of W?rzburg From ch.lange at jacobs-university.de Tue Jan 12 18:45:34 2010 From: ch.lange at jacobs-university.de (Christoph LANGE) Date: Tue, 12 Jan 2010 18:45:34 +0100 Subject: [goodrelations] CfP: Ontology Repositories and Editors for the Semantic Web (ORES2010 @ ESWC) Message-ID: <201001121845.38008.ch.lange@jacobs-university.de> ESWC 2010 Workshop on Ontology Repositories and Editors for the Semantic Web ORES 2010 - Call for papers and system descriptions - http://www.ontologydynamics.org/od/index.php/ores2010/ Heraklion, Greece - Deadline: March 1, 2010 The growing number of online ontologies makes the availability of ontology repositories, in which ontology practitioners can easily find, select and retrieve reusable components, a crucial issue. The recent emergence of several ontology repository systems is a further sign of this. However, in order for these systems to be successful, it is necessary to provide a forum for researchers and developers to discuss features and exchange ideas on the realization of ontology repositories in general and to consider explicitly their role in the ontology lifecycle. In addition, it is now critical to achieve interoperability between ontology repositories, through common interfaces, standard metadata formats, etc. ORES10 intends to provide such a forum. Illustrating the importance of the problem, significant initiatives are now emerging. One example is the Open Ontology Repositories (OOR) working group set up by the Ontolog community. Within this effort regular virtual meetings are organized and actively attended by ontology experts from around the world; The Ontolog OOR 2008 meeting was held at the National Institute for Standards in Technology (NIST), generating a joint communiqu? outlining requirements and paving the way for collaborations. Another example is the Ontology Metadata Vocabulary (OMV) Consortium, addressing metadata for describing ontologies. Despite these initial efforts, ontology repositories are hardly interoperable amongst themselves. Although sharing similar aims (providing easy access to Semantic Web resources), they diverge in the methods and techniques employed for gathering these documents and making them available; each interprets and uses metadata in a different manner. Furthermore, many features are still poorly supported, such as modularization and versioning, as well as the relationship between ontology repositories and ontology engineering environments (editors) to support the entire ontology lifecycle. Submitting papers and system descriptions We want to bring together researchers and practitioners active in the design, development and application of ontology repositories, repository-aware editors, modularization techniques, versioning systems and issues around federated ontology systems. We therefore encourage the submission of research papers, position papers and system descriptions discussing some of the following questions: * How can ontology repositories "talk" to each other? * How can the abundant and complex knowledge contained in an ontology repository be made comprehensible for users? * What is the role of ontology repositories in the ontology lifecycle? * How can branching and versioning be managed in and across ontology repositories? * How can ontology repositories interoperate with ontology editors, and other applications and legacy systems? * How can connections across ontologies be managed within and across ontology repositories? * How can modularity be better supported in ontology repositories and editors? * How can ontology repositories and editors use distributed reasoning? * How can ontology repositories support corporate, national and domain specific semantic infrastructures? * How do ontology repositories support novel semantic applications? * What measurements for describing and comparing ontologies can we use? How could ontology repositories use these? Research papers are limited to 12 pages and position papers to 5 pages. For system descriptions, a 5 page paper should be submitted. All papers and system descriptions should be formatted according to the LNCS format (http://www.springer.com/computer/lncs?SGWID=0-164-2-72376-0 ). Proceedings of the workshop will be published online. Depending on the number and quality of the submissions, authors might be invited to present their papers during a poster session. Submissions can be realized through the easychair system at http://www.easychair.org/conferences/?conf=ores2010 .

Most subscribers to this list are interested in using the GoodRelations ontology for practical purposes. For them, calls for papers to generic Semantic Web topics are not relevant. All researchers subscribed to this list will also be reached by posts to the more generic Semantic Web / Linked Data channels. I would hate to make this mailing list a moderated one to protect our subscribers. The only exception from the rule may be calls that are clearly and directly linked to e-commerce & linked data. Thanks for your understanding.

Here is how it will likely work: 1. Take the Amazon sitemap index files, as given by http://www.amazon.com/robots.txt # Sitemap files Sitemap: http://www.amazon.de/sitemap_index_0.xml Sitemap: http://www.amazon.de/sitemap_index_1.xml Sitemap: http://www.amazon.de/sitemap_index_2.xml Sitemap: http://www.amazon.de/sitemap_index_3.xml Sitemap: http://www.amazon.de/sitemap-manual-index.xml Sitemap: http://www.amazon.de/sitemap_wishlist_index.xml 2. Take the individual sitemap files from all of those, e.g. http://www.amazon.de/sitemap_page_0.xml.gz from http://www.amazon.de/sitemap_index_0.xml http://www.amazon.de/sitemap_page_0.xml.gz 2006-10-16 3. Now, for each of those ca. 20 Million entries given as elements, e.g. http://www.amazon.com/Pull-Power-Semantic-Transform-Business/dp/1591842778/ http://www.amazon.com/Pull-Power-Semantic-Transform-Business/dp/1591842778/ use the URIburner service (http://uriburner.com/sparql/) to extract the complete commercial meta-data in GoodRelations. Note that not all URIs are current and that URIburner cannot produce GoodRelations data for not all pages, but it can for the majority of the ca. 20 Million pages. You will get, on average, 200 GoodRelations triples per Amazon page, so the total will be in the order of magnitude of 4 billion ! (If you want to check it for yourself, try select COUNT (*) WHERE {?s ?p ?o. FILTER (regex(?o, "^http://purl.org/goodrelations/v1#", "i") or regex(?p, "^http://purl.org/goodrelations/v1#", "i")) } against the URI http://www.amazon.com/Pull-Power-Semantic-Transform-Business/dp/1591842778/ Important: Using URIburner on the full set of Amazon URIs will likely impose a great load on the underlying server, operated by OpenLink Software.

But in the meantime, you can use Kingsley's magical Sponger technology to get that data even without Amazon supporting it natively yet. An 4 billion GoodRelations triples is quite something, isn't it? And note that Spongers are not screen-scraping, but on-the-fly middleware from proprietary APIs to persistent publication of RDF using standardized vocabularies.

The reason is that both properties are just shortcuts for QUERYING data, so that, in a SPARQL query, you do not have to know whether you are handling a gr:QuantitativeValueInteger or gr:QuantitativeValueFloat. They MUST NOT be used for annotating data. So they must only occur in an RDF model that does include inferred triples (i.e. reasoning). If there is no reasoning, there MUST not be a triple with either gr:hasMaxValue and gr:hasMinValue properties. If there is reasoning, there will be a triple subject gr:hasMaxValue object for any triple of the form subject gr:hasMaxValueFloat object subject gr:hasMaxValueInteger object and a triple subject gr:hasMinValue object for any triple of the form subject gr:hasMinValueFloat object subject gr:hasMinValueInteger object Best wishes Martin Hepp -------------------------------------------------------------- martin hepp e-business & web science research group universitaet der bundeswehr muenchen e-mail: hepp at ebusiness-unibw.org phone: +49-(0)89-6004-4217 fax: +49-(0)89-6004-4620 www: http://www.unibw.de/ebusiness/ (group) http://www.heppnetz.de/ (personal) skype: mfhepp twitter: mfhepp Check out GoodRelations for E-Commerce on the Web of Linked Data! ================================================================= Project page: http://purl.org/goodrelations/ Resources for developers: http://www.ebusiness-unibw.org/wiki/GoodRelations Webcasts: Overview - http://www.heppnetz.de/projects/goodrelations/webcast/ How-to - http://vimeo.com/7583816 Recipe for Yahoo SearchMonkey: http://www.ebusiness-unibw.org/wiki/GoodRelations_and_Yahoo_SearchMonkey Talk at the Semantic Technology Conference 2009: "Semantic Web-based E-Commerce: The GoodRelations Ontology" http://www.slideshare.net/mhepp/semantic-webbased-ecommerce-the-goodrelations-ontology-1535287 Overview article on Semantic Universe: http://www.semanticuniverse.com/articles-semantic-web-based-e-commerce-webmasters-get-ready.html Tutorial materials: ISWC 2009 Tutorial: The Web of Data for E-Commerce in Brief: A Hands-on Introduction to the GoodRelations Ontology, RDFa, and Yahoo!

Example: For a simple offer, you could say that you offer to sell 200 grams of salami and that the price was 20 euros per kilogram of salami. Then, the gr:UnitOfMeasurement attached to the gr:TypeAndQuantityNode is "grams" (GRM in UN/CEFACT) and the gr:UnitOfMeasurement attached to the gr:UnitPriceSpecification is "kilogram" (KGM in UN/CEFACT). As soon as there is more than one component included in the offer, the only meaningful unit of measurement for the price specification is "C62" for unit or piece. Example: If you offer 200 grams of salami and 1 liter of beer for altogether 8 euros, then you would use "GRM" and "LTR" for the two gr:TypeAndQuantityNode instances and "C62" for the unit price specification. There can be rare cases of bundles that allow other units of measurement for the price specification, but as a rule of thumb, use C62 as soon as there is more than one component included the offer. Relevant exceptions can be found for business functions other than gr:Sell - e.g. Rental: If you offer to rent out a pair of skis and 2 tons of snow, then the price may be specified per hour (HUR in UN/CEFACT). But again, those cases are rare (yet still perfectly supported by GoodRelations).

Here is a shortlist of major examples. 1. BestBuy stores (ca. 1000) Simply fetch all URIs listed in http://stores.bestbuy.com/sitemap.xml 2. BestBuy offers (430,000) Simply fetch all URIs listed in http://products.semweb.bestbuy.com/sitemap.xml 3. O'Reilly Offers O'Reilly has started to add GoodRelations in RDFa to their production Web site, see e.g. http://oreilly.com/catalog/9780596007683 Their sitemap is t http://oreilly.com/sitemap.xml As far as we know, only pages of the pattern http://www.oreilly.com/catalog/* do contain relevant RDFa. 4. SaveOnVideo.com (8,000 products) SaveOnVideo.com exposes its full catalog of 8,000 items using GoodRelations in RDFa. Fetch all pages from http://www.saveonvideo.com/sitemap.xml 5. There is model data about the 500 most relevant camcorders at http://rdf4ecommerce.esolda.com/sitemap.xml. 6. http://productdb.org/ exposes product descriptions and reviews from ProductWiki using a blend of GoodRelations, FOAF and OpenVocab. There is also a SPARQL endpoint at http://api.talis.com/stores/productdb/services/sparql I don't know of a sitemap, but you can query the endpoint at http://api.talis.com/stores/productdb/services/sparql for all gr:ProductOrServiceModels SELECT ?m WHERE {m a fetch http://productdb.org/pioneer-ts-sw2541d.rdf 7. http://www.universum-shop.de has added GoodRelations + RDFa to all individual items Example: http://www.universum-shop.de/go/DP4Q2HE68YA7JM53XD3OOGVUYTJ5OW31?action=ProdDetails&product_uuid=SWBV7SQBGJMT68TOS9Z3CMWQJOKDS4UU Unfortunately, there is no sitemap.xml 8. OpenEAN: There is an RDF/XML transcript of 1 Mio product models and their EAN/UPC code at http://openean.kaufkauf.net/id/ The semantic (!) sitemap (mind the differing element names) is at http://openean.kaufkauf.net/sitemap.xml 9. The oxid eSales Shop: http://www.waffen-frank-shop.de/ has GoodRelations markup in all item pages. There is an RDF/XML dump at http://www.waffen-frank-shop.de/goodrelations/output.rdf The content in the dump is identical to the RDFa markup in all individual pages, e.g. Example: http://www.waffen-frank-shop.de/Zubehoer/Messer/Tools/My-first-Victorinox-Kindermesser-oxid.html 10. Magento Shop: http://www.la-mousson.de/ has GoodRelations markup in all item pages. Example: http://www.la-mousson.de/levante-weiss-gruener-tee.html Fetch http://www.la-mousson.de/sitemap.xml and extract the RDFa markup from all pages. Most of those should be recrawled every 24 hours. This is just a shortlist, and I am currently in contact with many major online retailers on adding GoodRelations to their sites.

Keep in mind that the rest of LOD data seems to account for a total of only 8 billion triples for the moment Second: Yes, I of course hope that Amazon will be among the early adopters of GoodRelations, in particular given that there is now growing evidence that this does two things in one turn: 1. Have a positive impact on ranking in current search engines and 2. Pave the ground for much better visibility in the evolving Web of Linked Data. And yes: If anyone has high-profile contact to Amazon, I would appreciate being introduced. I have been approached by the Web development leads of ca. ten large online retailers and am helping them add GoodRelations to their pages. It would surprise me if Amazon wanted to be a follower in that field.

It could be an important contribution for both lifting existing offer data to GoodRelations and for augmenting existing GoodRelations data by mining additional links from rdfs:comment and rdfs:label properties. http://www.opencalais.com/ Best wishes Martin Hepp -------- Original Message -------- Subject: OpenCalais Release 4.3 is available! Date: Wed, 20 Jan 2010 09:32:26 -0500 From: The Calais Team To: Today we released version 4.3 of the OpenCalais service, as well as key updates to both our Tagaroo plugin for WordPress and SemanticProxy, our URL submission service. Release 4.3 features enhanced Social Tags for categorization; improved disambiguation; new entities, facts and events in English; and an entirely new feature, News Names. * Improved ?Social Tags?: We have expanded on our popular social tags categorization technique with more generalized, aggregate tags. For example, if a blogger is comparing the racing performance of sports cars like the Ferrari 308 GTB and Porsche 959, OpenCalais 4.3 will suggest auto racing and motorsport as Social Tags, in addition to the more obvious sports cars. * News Names: We are instituting a process of name normalization that represents a first step toward our more robust vision for person disambiguation. For a partial or extended name appearing in content, OpenCalais 4.3 will suggest the most commonly used form of that same name. For example, for articles containing Barack Obama, Obama or Barack Hussein Obama, OpenCalais will suggest Barack Obama. * New Entities, Facts and Events in English: See the new Natural and Manmade Disaster attributes, supporting data for upcoming events (Movies, Music Albums, and anticipated Medical Treatments), Political entities, facts and events, and enhanced Person Career extraction. We listened to you and have improved Tagaroo with more user control over tagging. We have also normalized SemanticProxy processing to ensure that its results are identical with those you'd get by programmatically submitting content to OpenCalais via the API. Additionally, you can now specify a callback function when requesting results in JSON. This release also features an updated Calais ontology in OWL, improved Simple Format and Microformat outputs, and several extraction bug fixes. See the full release notes for more details on Release 4.3.
