PhotoCity rarolla ka boleng data le mohlala mathata a ka pokello aba ya data.
Websites kang Flickr le Facebook nolofalletsa batho ho kopanela litšoantšo le metsoalle le ba lelapa la bona, empa ba boela bōpa repositories ea tonanahali ea difoto e ka sebelisetsoa merero e meng. Ka mohlala, Agarwal et al. (2011) e leka ho sebelisa foto ena ho "Hahang Roma ka Letsatsi le" ka ho sebelisa 150.000 litšoantšo tsa Roma ho bopa tsosolosa 3D ba motse. Bakeng sa ditsha tsa bohahlauli e kang ona oa Coliseum ho ne ho litšoantšo tse lekaneng Inthaneteng ho hlahisa dikai 3D (Figure 5.10), empa boleng ba reconstructions tsena li ne li felle ke taba ea hore foto ka ho fetisisa ba ile ba isoa ho tloha tshwaneng tšoanang boemohali, ba siea likarolo tse itseng tsa mehaho e melelele unphotographed. Ho ekelletsa moo, bakeng sa likarolong tse ngata tsa motseng, foto ha hoa lekana ne fumaneha. Kahoo, a sebelisa ya data fumanoa tsoang Foto repositories, ho ne ho ke ke ha khoneha ho didirisiwa tse eohle ea Roma. Empa, ho thoe'ng haeba baithaopi ka kōpa ho bokella difoto ho hlokahala hore ho e le kannete "Iketsetse Roma ka Letsatsi le"?
E le hore a etsa hore pokello targeted ea palo e khōlō ea photos, Kathleen Tuite le basebetsi-'moho ntshetswa PhotoCity, papaling foto-uploading. Karolong e le nngwe e ntle ea PhotoCity ke hore e ile mosebetsi nang le monyetla o khathatsang ya data pokello-uploading difoto-ho fihlela papali-joaloka mosebetsi amang lihlopha tsa basebetsi, liqhobosheaneng, 'me lifolakha (Figure 5.11). Ho etseng lipolane tsa PhotoCity boetse elegantly rarolla ka ea mohlala le data boleng liphephetso tsa eBird le ho aba merero e meng pokello ya data.
PhotoCity ile la pele malala ho etsa hore a tsosolosa 3D tsa liunivesithi tse peli: Cornell University le Univesithing ea Washington. Players ka leng khamphaseng ka hlahloba puso morao-rao tsa ea mohlala tsosolosoe khamphaseng bona. Joale, ba ka fumana chelete lintlha tse ka uploading litšoantšo tseo atolosa ea mohlala hajwale. Ka mohlala, haeba ea mohlala morao-rao tsa Uris Library (ka Cornell) e ne e patchy haholo, sebapala a ka fumana lintlha tse ka uploading litšoantšo tse ncha tsa eona. Nyatsa-nyatsa, lifoto tse neng li uploaded lokela lepelela le difoto teng hajoale e le hore ba ka tiisitsoe ka oona, 'me palo ea lintlha sebapala sa fumaneng e thehiloeng tjhelete eo foto ea bona phaella ka ho re ho ea mohlala hajwale. Qetellong, bafuputsi ba ile ba khona ho sebelisa foto tsena uploaded ho bopa phahameng qeto dikai 3D tsa mehaho e melelele mo dikhamphaseng ka bobeli (Figure 5.12 buka).
Ho etseng lipolane tsa PhotoCity elegantly rarolla ka mathata a mabeli: ya data netefaletsokaelo le mohlala. Taba ea pele, foto ne ba tiisitsoe ka oona ke matching khahlanong le difoto mehleng tse neng li ka lehlakoreng le leng matched ho difoto mehleng tsela eohle khutlisetsa ho difoto tsa peō eo ba ne ba uploaded ke bafuputsi. Ka mantsoe a mang, ka lebaka la redundancy ena a haha-ka, ho ke ke le thata haholo kaha tsamaiso ea ho amohela ya data tse mpe. Ea bobeli, bona maduo tsamaiso ka tlhaho koetlisa barupeluoa ho bokella ka ho fetisisa tsa bohlokoa-eseng ka ho fetisisa loketseng-ya data. Ha e le hantle, mona ke tse ling tsa maano a hore libapali li hlalosoa sebelisa e le hore a fumane chelete lintlha tse eketsehileng, e leng lekanang le a ho bokella ya data bohlokoa ho (Tuite et al. 2011) :
- "[Ke ile ka leka ho] batlang li atametse ho nako ea motšehare le mabone hore ba bang litšoantšo ba isoa; sena se ne se thusa ho thibela hlouoa ke papaling. Eaba o re, matsatsi a koahetsoeng ke maru e ne e le molemo ka ho fetisisa haholo ha re sebelisana le likhutlong hobane ka tlaase ho moo ha ho bapisoa thusa papali palo ntša jometering tsoang litšoantšo tsa ka. "
- "Ha ho ne ho chabile, ke sebelisoa khamera oa ka-ba khahlanong le Shake ditshebetso tse ho dumella ho fihlela ke nka lifoto ha a ntse a tsamaea ho potoloha ea molebeli oa libaka itseng. Sena se nthusitse hore ke nke lifoto hlasimollang ha a ntse a ho se be le ho thibela stride ka. Also bonase: tlaase ho moo batho sheba nakong 'na'!
- "Ho litšoantšo tse ngata tsa kaho le 'ngoe le 5 megapiksele khamera, joale ho tla lapeng ho ikokobelletsa, ka linako tse ling fihlang ho gigs 5 ka mafelo a beke thunyana, e ne e ka sehloohong Foto nkhape leano lena. Ho hlophisa lifoto tse difoldara Link hard drive ya ka kaho tikolohong khamphaseng, ho haha, joale sefahleho sa mohaho oa fana ka baeta molemo ho Sebopeho Uploads. "
Lipolelo tsee tsoang barupeluoa bontša hore ha ba fane ka ditshwaelo loketseng, ba ka be setsebi haholo nakong bokella ya data thahasella bafuputsi.
Ka kakaretso, 'ngoe kahong eo PhotoCity bontša hore mohlala le data boleng ba sa mathata hlōloa ka pokello kabo ya data. Ho ekelletsa moo, e bontša hore boitsebiso bo aba diporojeke pokello ha e felle mesebetsi eo batho ba se ba ntse ba etsa joalo, tse kang ho shebella linonyana. Le moralo le letona, baithaopi ka ho khothalletsoa ho etsa lintho tse ling hape.
