2.3.2.6 Dirty

Loj cov ntaub ntawv qhov chaw yuav loaded nrog junk thiab spam.

Ib txhia soj ntsuam ntseeg tau hais tias loj cov ntaub ntawv qhov chaw, tshwj xeeb tshaj yog cov neeg ntawm hauv internet qhov chaw, yog pristine vim hais tias lawv yog sau tau. Nyob rau hauv qhov tseeb, cov neeg uas tau ua hauj lwm nrog loj cov ntaub ntawv qhov chaw paub hais tias lawv yog nquag qias neeg. Uas yog, lawv nquag muaj xws li cov ntaub ntawv uas tsis muaj kev cuam tshuam tiag tiag kev ua ntawm kev txaus siab rau kev soj ntsuam. Muaj ntau cov kev sib raug zaum no twb paub cov txheej txheem ntawm kev tu loj-scale social daim ntawv ntsuam xyuas cov ntaub ntawv, tab sis tu loj cov ntaub ntawv qhov chaw yog ntau yooj yim rau ob tug yog vim li cas: 1) lawv tsis tau tsim los ntawm kev soj ntsuam rau kev soj ntsuam thiab 2) soj ntsuam feem ntau muaj tsawg nkag siab txog ntawm yuav ua li cas lawv tau tsim.

Cov kev piam sij ntawm qias neeg cov cim tseg cov ntaub ntawv yog taw qhia los ntawm Back thiab lug txhawb cov miv ' (2010) txoj kev tshawb no ntawm lub siab ntsws teb rau cov kev tawm tsam ntawm lub Cuaj hlis 11, 2001. Cov neeg tshawb fawb feem ntau kawm cov lus teb rau tragic cov txheej xwm uas siv cov retrospective cov ntaub ntawv sau tshaj lub hlis los yog txawm xyoo. Tab sis, Back thiab lug txhawb cov miv pom ib tug yeej ib txwm nyob rau qhov chaw ntawm lub digital ib co kua nplaum-lub timestamped, txiav kaw lus los ntawm 85,000 American pagers-thiab qhov no enabled tus neeg tshawb fawb kawm kev xav teb rau ib tug ntau npaum li cas finer timescale. Rov qab thiab lug txhawb cov miv tsim ib pliag-by-feeb kev xav ncua sij hawm ntawm lub Cuaj Hli Ntuj 11 los ntawm coding lub siab ntsws cov ntsiab lus ntawm cov pager lus los ntawm cov feem pua ​​ntawm cov lus hais txog kev (1) tu siab (xws li, quaj, kev tu siab), (2) kev ntxhov siab vim (eg, txhawj xeeb, ntshai), thiab (3) txoj kev chim siab (piv txwv li, kev ntxub, kev). Lawv nrhiav tau tias kev tu siab thiab ntxhov siab vim fluctuated thoob plaws hauv lub hnub tsis muaj ib tug muaj zog txawv, tab sis hais tias muaj yog ib tug tawm kev nce rau hauv kev npau taws thoob plaws hauv lub hnub. Qhov no kev tshawb fawb mas, yuav tsum ib tug zoo lus piv txwv txog lub hwj chim ntawm ib txwm-rau cov ntaub ntawv qhov chaw: siv txuj kev nws yuav tsis yooj yim sua kom muaj xws li ib tug high-kev daws teeb meem ncua sij hawm ntawm qhov tam sim ntawd cov lus teb rau ib tug npaj txhij txog kev tshwm sim.

Cia li ib xyoos tom qab, Txawm li cas los, Cynthia Pury (2011) ntsia cov ntaub ntawv ntau kom zoo zoo. Nws nrhiav tau hais tias ib tug loj tus naj npawb ntawm cov supposedly npau taws lus tau generated los ntawm ib tug pager thiab lawv twb tag nrho tib yam. Ntawm no yog dab tsi cov supposedly npau taws lus hais tias:

"Reboot NT tshuab [name] nyob rau hauv txee [name] ntawm [qhov chaw]: TSEEMCEEB HEEV: [date thiab lub sij hawm]"

Cov lus raug sau tias npau taws vim hais tias lawv muaj lo lus "qhov TSEEMCEEB HEEV", uas tej zaum yuav feem ntau qhia kev chim siab tab sis tsis nyob rau hauv cov ntaub ntawv no. Tshem cov lus generated los ntawm qhov no ib automated pager kiag li eliminates lub khees nce nyob rau hauv txoj kev chim siab nyob rau thaum kawg ntawm lub hnub (Daim duab 2.2). Nyob rau hauv lwm yam lus, lub ntsiab tshwm sim nyob rau hauv Back, Küfner, and Egloff (2010) yog ib tug yam cuav ntawm ib pager. Raws li qhov piv txwv no qhia txog, kuj yooj yim tsom xam ntawm kuj complex thiab ntxhov ntaub ntawv muaj lub peev xwm mus tiag tsis ncaj ncees lawm.

Xam 2.2: Kwv yees li ntawm tiam sis nyob rau hauv txoj kev chim siab nyob rau thaum kawg ntawm lub Cuaj hlis 11, 2001 raws li 85,000 American pagers (Back, Küfner, and Egloff 2010; Pury 2011; Back, Küfner, and Egloff 2011) . Keeb xeeb, Back, Küfner, and Egloff (2010) qhia txog ib tug qauv zuj zus txoj kev chim siab thoob plaws hauv lub hnub. Txawm li cas los, feem ntau ntawm cov khees npau taws lus tau generated los ntawm ib tug pager uas pheej xa tawm cov lus nram qab no: "Reboot NT tshuab [name] nyob rau hauv txee [name] ntawm [qhov chaw]: TSEEMCEEB HEEV: [date thiab lub sij hawm]". Nrog cov lus no muab tshem tawm, lub khees nce nyob rau hauv txoj kev chim siab disappears (Pury 2011; Back, Küfner, and Egloff 2011) . Qhov no xam yog ib tug tu tub tu kiv ntawm daim duab 1B nyob rau hauv Pury (2011) .

Thaum qias neeg cov ntaub ntawv uas yog tsim unintentionally-xws li los ntawm ib tug nrov pager-yuav yuav ntes tau los ntawm ib tug tubntxhais ceev faj soj ntsuam, tseem muaj ib co hauv internet systems uas nyiam txhob txwm spammers. Cov spammers nquag tsim fake cov ntaub ntawv, thiab-feem ntau kev mob siab los ntawm nyiaj-ua hauj lwm nyuaj heev kom lawv spamming zais. Piv txwv li, kev nom kev tswv ua si rau Twitter nkawd muaj tsawg kawg yog ib co tubntxhais sophisticated spam, uas ib co nom tswv ua yog txhob txwm ua saib nrov tshaj lawv tiag tiag yog (Ratkiewicz et al. 2011) . Soj ntsuam ua hauj lwm nrog cov ntaub ntawv uas tej zaum yuav muaj txhob txwm spam fim cov kev sib tw ntawm kev yaum lawv cov neeg tuaj saib uas lawv tau ntes tau thiab muab tshem tawm yam spam.

Thaum kawg, dab tsi yog xam tau tias yog qias neeg cov ntaub ntawv yuav nyob ntawm seb nyob rau hauv kev hloov maj mam txoj kev nyob rau hauv koj cov kev tshawb fawb cov lus nug. Piv txwv li, muaj ntau yam edits rau Wikipedia yog tsim los ntawm cia li bots (Geiger 2014) . Yog hais tias koj xav nyob rau hauv lub ecology ntawm Wikipedia, ces cov bots yog ib qho tseem ceeb. Tab sis, yog hais tias koj xav nyob rau hauv yuav ua li cas cov tib neeg ua rau kom Wikipedia, cov edits ua los ntawm cov bots yuav tsum raug tshem tawm.

Qhov zoo tshaj plaws txoj kev uas kom tsis txhob raug haib haib qias neeg cov ntaub ntawv yog kom to taub yuav ua li cas koj cov ntaub ntawv tau tsim los ua tej yam yooj yim exploratory tsom xam, xws li ua tej yam yooj yim nphoo zajlus.
