From hepp at ebusiness-unibw.org Wed Jul 1 18:20:53 2009 From: hepp at ebusiness-unibw.org (Martin Hepp (UniBW)) Date: Wed, 01 Jul 2009 18:20:53 +0200 Subject: [goodrelations] UML Class Diagram for GoodRelations Message-ID: <4A4B8CE5.6020908@ebusiness-unibw.org> Dear all: Many of you asked me for a UML class diagram of the GoodRelations ontology - I am working on one that reflects the latest state of the ontology - apologies for the delay. Attached, please find two illustrations that are neither nicely designed nor completely accurate, but they may already be helpful as a first orientation. The final diagram will also be included in the updated HTML documentation for the ontology. If anybody of you knows a good tool for deriving UML class diagrams from OWL ontologies in a way that allows editing the final diagram, I would very much appreciate that. The plug-in for Prot?g? 4.0 http://protegewiki.stanford.edu/index.php/OWL2UML creates only a .png file of unsatisfying quality and the online tool at http://owl2xmi.sourceforge.net/ http://swap.uib.es:8080/owl2xmi/ exports only XMI 1.0 as far as I can see.

As for the two issues: a) Using URIs for CEFACT units of measurement instead of plain strings. ========================================================= The motivation for recommending gr:hasUnitOfMeasurement "GRM"^^xsd:string . instead of gr:hasUnitOfMeasurement rec20:GRM was (and still is) that at the time of releasing GoodRelations, there was no authoritative URI schema for UN/CEFACT available. The only official resource is http://www.unece.org/cefact/recommendations/rec20/rec20_rev4E_2006.xls I think such an authoritative URI schema for UN/CEFACT codes would be valuable, but it is not there, and GoodRelations should not have been delayed by that. A key design principle for GoodRelations is to built on currently available standards and tools - here and now, today. Also, using URIs for those codes would be most useful if those URIs were dereferencable, which will likely not be the case if we just make up a URI pattern. Creating that may also require legal clearance from the UN. I tried the same for the UNSPSC and have been unable to release a proper OWL transcript for 1.5 years now. A second requirement for me is that any OWL ontology or simple URI schema for UNCEFACT is immediately in sync with any update of the UN/CEFACT schema. I cannot rely on an OWL/RDFS or lightweight LOD transcript of the codes that will only be maintained as long as the sponsoring research project is up and running or the PhD student is interested in the work. (There are dozens of non-maintained, outdated "single snapshot" transcripts of various coding schemes in OWL or RDFS on the Web. They are not only useless but dangerous traps for businesses adopting the technology. If you want, I can send you pointers, but I don?t want to blame anyone publicly.) The current approach decouples the evolution of GoodRelations and the evolution of the UN/CEFACT code. We also considered Wikipedia/dbPedia URIs (same for currencies and locations), but again, there is the problem of a) keeping that in sync with updates of the standard, and, more difficult, making sure that a user can easily generate the URIs from the proper UN/CEFACT code string, because that is what they have in their RDBMS. By the way, I think it should be possible to map the current GoodRelations pattern to any such URI schemes using restrictions on string values or regex patterns within SPARQL CONSTRUCT queries. So, IMO, the current modeling does not create, any future compatibility problem while ensuring GoodRelations can be adopted immediately (and it is). Bottom line: If there is an authoritative, and ideally dereferencable, URI schema for UN/CEFACT unit codes, I will be happy to consider changing the range from xsd:string to URI. Until then, I think that the current approach serves businesses best (that code as a string is used in thousands of corporate databases as of today). b) rdf:value instead of gr:hasValueInteger (and gr:hasValueFloat, respectively) ========= rdf:value can be useful for point values, but note that xyz gr:hasValueInteger "1"^^xsd:int is a shortcut for xyz gr:hasMinValueInteger "1"^^xsd:int xyz gr:hasMaxValueInteger "1"^^xsd:int because GoodRelations models *all* quantitative values as intervals instead of point values, because this allows simple queries using range constraints, both on the supply side ("we repair TV sets between 0 and 50 inches screen size") and the demand side / query ("find all TV sets with at least 20 inches screen size"). This has shown to be very, very helpful for many real-world scenarios. The details are given in http://www.heppnetz.de/projects/goodrelations/primer/#5.1_Handling_of_Ranges_and_Intervals and in the technical report at http://www.heppnetz.de/projects/goodrelations/GoodRelations-TR-final.pdf Also, http://www.w3.org/TR/rdf-primer/#example21 explicitly says that rdf:value is just one way of representing values. I also do not see your owl:Restriction and owl:allValuesFrom patterns working well with very lightweight reasoning support. GoodRelations, but intension, requires just transitivity of rdfs:subClassOf and rdfs:subPropertyOf. (It could also be that rdf:value a owl:DatatypeProperty turns the model into OWL Full, not sure about that.) Hope that clarifies the motivation for the GoodRelations design choices.

The study suggests that many consumers leave the site mainly because they want additional information before completing the transaction. Even if many of those would have been willing to buy at that site, eventually, they don't do so because they never come back from their searches for additional information. Most important reasons for cart abandonment: -- High shipping charges: 46 percent -- Wanted to comparison shop: 37 percent -- Wanted to shop offline: 26 percent -- Couldn't find preferred pay option: 24 percent The important thing for me in here is that merchants LOOSE money because they don't make available important details for the customers. It is not that the potential buyers are eventually not convinced of the offer. It is that they want to have more information before completing the purchase and get lost somewhere in the Web when searching for additional information. Or they are not directly pointed to a store related to the online presence. With GoodRelations, any merchant could provide such details and empower what I call "Deep Comparison Shopping". For the full study, see http://www.cnbc.com/id/31506399/site/14081545 For a presentation on "Deep Comparison Shopping", see http://www.slideshare.net/mhepp/deep-comparison-shopping-1591651 For the abstract of my upcoming invited talk at EC-Web 2009 entitled "Product Variety, Consumer Preferences, and Web Technology: Can the Web of Data Reduce Price Competition and Increase Customer Satisfaction?", see http://www.heppnetz.de/files/56920144.pdf Best Martin Hepp ---------------------------------------------------------- martin hepp e-business & web science research group universitaet der bundeswehr muenchen e-mail: mhepp at computer.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 the GoodRelations vocabulary for E-Commerce on the Web of Data! ======================================================================== Webcast: http://www.heppnetz.de/projects/goodrelations/webcast/ Talk at the Semantic Technology Conference 2009: "Semantic Web-based E-Commerce: The GoodRelations Ontology" http://tinyurl.com/semtech-hepp Tool for registering your business: http://www.ebusiness-unibw.org/tools/goodrelations-annotator/ Overview article on Semantic Universe: http://tinyurl.com/goodrelations-universe Project page and resources for developers: http://purl.org/goodrelations/ Tutorial materials: Tutorial at ESWC 2009: The Web of Data for E-Commerce in One Day: A Hands-on Introduction to the GoodRelations Ontology, RDFa, and Yahoo!

The new version is at http://www.unece.org/cefact/recommendations/rec20/Rec20_Rev6e_2009.xls The previously used version for GoodRelations is at http://www.unece.org/cefact/recommendations/rec20/rec20_rev4E_2006.xls Effective immediately, the range of gr:hasUnitOfMeasurement (http://purl.org/goodrelations/v1.html#hasUnitOfMeasurement) changes to Revision 6 (official symbol: CEFACT/ICG/2009/IC011). The ontology specification has not changed. Since the UN/CEFACT puts a lot of effort into keeping revision changes backward compatible, this will not require immediate action for almost anybody.

The new version is not yet online, but I wanted to align with you on advance. The full change-log (preview) is at http://tr.im/sFCp All changes are minimal and should not create incompatibilities with existing data. Please let me know if you foresee any problems or have concerns. The following things may be of particular interest for you: 1. The new gr:seeks property for modeling the buy side. 2. The new gr:includes property is a nice shortcut for the 90% of the cases where only a single item of a certain product is in the offering. In the past, you were forced to introduce a TypeAndQuantityNode with a quantity of 1.0 and a unit of "C62". This may simplify RDFa markup in particular. However, note that this is just a shortcut and we recommend using a simple SPARQL rule like #rule for new includes property PREFIX gr: CONSTRUCT { _:n rdf:type gr:TypeAndQuantityNode. _:n gr:AmountOfThisGood "1.0"^^xsd:float. _:n gr:hasUnitOfMeasurement "C62"^^xsd:string. ?a gr:includesObject _:n . _:n gr:typeOfGood ?b.} WHERE {?a rdf:type gr:Offering. ?b rdf:type gr:ProductOrService. ?a gr:includes ?b} for creating the long, canonical form. 3. A new property for inventory levels, attached to gr:ProductsOrServicesSomeInstancesPlaceholder http://purl.org/goodrelations/v1#hasInventoryLevel 4. Disjointness axioms for the core classes.

The eBay individual auction pages use murky HTML 4.01 markup; that would require commitment from eBay to clean up. And the power seller pages at least use XHTML 1.0 transitional as a doctype, but also contain flaws in the header / template, so even a well-minded seller could not include RDFa in a fully compliant way. But Yahoo will be tolerant to that: Quote: "Our extractor does attempt to pull valid RDFa out of murky pages. If eBay embedded GoodRelations RDFa in their "tag soup" pages, we would extract it (unless the page is *very* badly malformed, to the point that it defeats out extractor codec completely)."

In 80% of the cases, this should be 1.0 ("1.0"^^xsd.float), because the price etc. is for one item. A value other than 1.0 is appropriate when you sell a bundle of items or use units of measurement other than "item/piece", e.g. selling "100 tiles" "500 g of butter", or "1 camera + 2 memory sticks" gr:hasInventoryLevel, on the contrary, can be used to indicate inventory levels. While gr:amountOfThisGood is an owl:DatatypeProperty, gr:hasInventoryLevel is an owl:ObjectProperty with a range of gr:QuantitativeValueFloat, because this allows for using arbitrary units and also specifying ranges. It can only be attached to instances of gr:ProductOrServicesSomeInstancesPlaceholder. So if you want to indicate inventory levels, use gr: hasInventoryLevel in combination with an instance of gr:QuantitativeValueFloat. *Example:* Assume you have 80 pieces of this controller card on stock. Then, use the following pattern: *_N3:_* foo:myProduct a gr:ProductOrServicesSomeInstancesPlaceholder; rdfs:label "Personal SCSI 16-bit SCSI Controller"@en ; gr:hasEAN_UCC-13 "00010363780"^^xsd:string ; gr:hasManufacturer ; rdfs:comment "This low-cost, high-performance SCSI controller allows you to connect up to seven professional mass-storage devices to your computer."@en ; rdfs:seeAlso , ; foaf:depiction ; * gr:hasInventoryLevel [ a gr:QuantitativeValueFoat; gr:hasValueFloat "80"^^xsd:float ; gr:hasUnitOfMeasurement "C62"^^xsd:string ] ;* . RDFa:

And that is something GoodRelations meta-data will make a lot more powerful. So I see no reason to assume a reduced importance of SearchMonkey. More likely it will quickly increase the scope of SearchMonkey from Yahoo to Yahoo+Bing. Also note that an even bigger business benefit for companies will be be high-quality traffic generated via GR-powered affiliate marketing etc., which does not require Yahoo crawling. Yahoo is important for encouraging the small businesses to create an initial data set. A huge business potential will be in complementing systems that use the respective data in more depth and breadth than Yahoo. It may be Bing, it may be a novel vendor ;-) We will see...
