OntologyMaturingandSOBOLEOSomeimportantworkthatreconcilesmore(traditional)formalapproachestoontologydevelopmentwithmoreparticipative(Web2.

Thestartingpointoftheirontologymaturingprocessmodelweretheshortcomingsoftheusualseparationofcreationandusageprocesses,performedbydifferentsetsofpeople[9].
Whilethismightbepossibleinratherstaticdomains,itisnotacceptablefordynamicdomains,especiallywhenusingontologiesfortheannotationandretrievalofresources,wherecontentschangefastandtheontologyrequiresapermanentupdatetocovertheavailablecontents.
Inrealworldsetups,thisleadstofrustratingsituations(whichisamajorproblemforacceptance)whenuserscannotextendtheusedontologiesbythemselvesinawork-integratedway,e.

whentheyrequirethemforthesemanticannotationofweb-pages.
Instead,theyareforcedtoaskontologyexpertsfortheextensionandwaitfortheupdateoftheunderlyingontologies,which–inverydynamicdomains–canevenlastuntiltheontologyelementhasbecomeobsoleteagain[10].
Thisled[8]torethinkontologyengineeringasacollaborativeandwork-integratedactivity.
Inthisview,usersthemselves(within,e.
g.
,communitiesofpractice)canmodifytheunderlyingontologyofasemanticapplication,e.
g.
,addnewontologyelementsormodifyexistingones.
Thisnewperspective,motivatedbyconstructivistviewsoflearning(seealso[11]),viewsthequalityofanontologywithinthecontextofasemanticapplicationasabalanceofthreedifferentaspects:appropriateness,socialagreementandformality[8].
Anontologyneedstobeanappropriaterepresentationofthedomainwithrespecttothepurposeoftheontologiesrequiredforasemanticapplicationsothatitisactuallyuseful.
Thatmeans,weneedaquick,simpleandwork-integratedwaytoadaptandmodifytheontologies.
Theaspectofsocialagreementrequiresthatanontologyisasharedunderstandingofagivendomainamongallstakeholders.
Therefore,theinvolvedindividualsdeepenbyandbytheirunderstandingoftherealworldandofan(appropriate)vocabularytodescribeit.
Thedevelopmentofanontologyunderliesaprocessofcontinuousevolutionwheredifferentlevelsofformalitymightco-existwithinoneontology.
Theoutcomeisanadequatelevelofformalityintheontology,avoidingbothoverformalisationandtheinabilitytoapplysemanticalgorithms.
Thisbalancecomesupinacontinuoussociallearningprocesstightlycoupledwiththeusageprocessesoftheontology.
Theontologymaturingprocessmodeloperationalizesthisviewandstructurestheontologydevelopmentprocessintofourphases.
Startingwithsimpletags,eachusershallcontributetothecollaborativedevelopmentofontologies.
Thus,eachcommunitymembercancontributenewideas(tags)emergingfromtheusagetothedevelopmentofontologies(phaseI"EmergenceofIdeas").
Thecommunitypicksthemup,consolidates,andrefinesthem(phaseII"ConsolidationinCommunities")andformalizeswithsemanticrelationstowardslightweightontologies(phaseIII"Formalization")orevenaddsaxioms(maybewithsupportofknowledgeengineers)forimprovinginferencingprocesses(phaseIV"Axiomatization").
Inthiswaytheusersthemselvescandirectlyexecutechangesifneeded.
Thetimeandcost-consumingseparationofontologycreationandusageisovercome.
TheSOBOLEOtool(below)realizesthisontologymaturingprocessmodelbyofferinganeasy-to-useinterface(toallowtheusageofsemantictechnologiesalsofor"ordinary"people)andontologydevelopmentintegratedintotheactualusageprocesses;i.

Sobelowwemakeaninitialattempttosummarisehowtheproposedmashupmightassistwiththeseprocesses.
Buttobeginwithitmightbeusefultosketchaconceptualoverviewofhowthismightwork.
Essentially,theP.

isconstructingaknowledgerepresentation,ordomainmodel,throughcontinuouson-taskactivities(suchasbookmarkingthroughSOBOLEO)andthroughperformingadialoguewithandaboutthedevelopingontologyanditsinstantiationwithLMI.
Thisengineofa(continuouslydeveloping)knowledgerepresentationplusvariousdialoguefacilitiescanthensupportarangeoffeaturesassociatedwiththedevelopmentandapplicationoftheknowledgeforadvisingandproblemsolving.
Thesefeaturescouldbeproductivelyoperationalisedalongthelinesbelow.

Thiscouldbeassistedthroughusinglocation-basedinformationtoautomaticallydirecttheP.

免费注册宝塔面板账户赠送价值3188礼包适合购买抵扣折扣

对于一般的用户来说,我们使用宝塔面板免费版本功能还是足够的,如果我们有需要付费插件和专业版的功能,且需要的插件比较多,实际上且长期使用的话,还是购买付费专业版或者企业版本划算一些。昨天也有在文章中分享年中促销活动。如今我们是否会发现,我们在安装宝塔面板后是必须强制我们登录账户的,否则一直有弹出登录界面,我们还是注册一个账户比较好。反正免费注册宝塔账户还有代金券赠送。 新注册宝塔账户送代金券我们注册...
