Nyora nezvezvinetso zvetsika zvinogona kuvapo pamashandisiro anoita nzira dzokuita kuti vanhu vasazivikanwa.
Imwe yenyaya dzetsika dzine chokuita nounyanzvi hwokudzvinyirira ndeyokumwe kusanyatsomiririrwa kwemapoka akambomiririrwa zvishoma. Somuenzaniso, mukati meMOOC dataset pane mutsara mumwe chete wakabatana nemushandisi kubva kuAntarctica (nyika). Nenzira yakafanana, nyika dzinotevera dzakaonekawo kamwe chete kana kaviri chete mudasetet yose: San Marino, Falkland Islands, uye Brunei. Nemhaka yokusawanwa zvakakwana munharaunda, mashoko aya aizobviswa chose chose kupfurikidza nenzira yokudzvinyirira. Izvi zvinopa chirevo chetsika: kune rumwe rutivi, tinoda kuchengetedza k-kusazivikanwa uye kuchengetedza zvakavanzika zvevashandisi vanobva kumatunhu asina kumiririrwa; kune rumwe rutivi, kuzadzisa chinangwa ichocho isu taizofanira kudzima kuvapo kwavo mu dataset uye nekuwedzera kusimbisa iko kushomeka kuripo. Mumwe muenzaniso ungava mukoramu yegore rokuzvarwa. Vashandisi veMOOCs vanonyanyomiririrwa nevechidiki, nepo vashandisi vane makore anodarika makumi masere ekuberekwa vachitora chikamu chidiki pane 1% mudhata rese. Zvikurukuru, kudai taizoshandisa unyanzvi hwokudzvinyirira kuwana k-kusingazivikanwi, inodokuva mashoko ose akabatanidzwa navashandisi vanopfuura makore 80 aizofanira kuraswa. Zvakare, vanhu vakwegura vave vachishayikwa munhoroondo mumhizha yedzidzo, asi kupfurikidza nokushandisa kudzvinyirira, tinodzivirira mararamire avo voga pamutengo womumiririri.  Uku kurasikirwa nokumiririrwa somuuyo wokudzvinyirira kunokuvadza mumativi akawanda uye naizvozvo kunofanirwa ngwariro. Sezvo nzvimbo yeMOOCs isina ruzivo rwakakodzera pamusoro pevashandisi ava, kambani icharasikirwa nechinangwa chekuda kuti mapoka aya asina kumiririrwa ave nedzidzo yepaIndaneti, nokudaro achitadza kusvika kwavari kuburikidza nekutengesa uye kushambadzira. Kunze kwekutambudza vashandisi vepuratifomu uye purofiti, izvi zvaizowedzera mamiriro ezvinhu ekuti mapoka asina kumiririrwa ane zviwanikwa zvishoma zvedzidzo yepamhepo. Zvakare, kufungidzira pane dhata yakadzvinyirirwa kunogona kusimbisa kusarura kwenzanga kuti mamwe mapoka evanhu haana kuvhurika dzidzo <unk> sevakweguru <unk> nepo chokwadi chiripo ndechekuti tinongobvisa ruzivo rwevakweguru vanobatanidzwa zvakanyanya mumapuratifomu edzidzo epamhepo. Somugumisiro, vakwegura vangazviona vava kure zvikuru nenhepfenyuro huru uye unyanzvi hwokugadzira zvinhu. Naizvozvo, kushandisa kudzvinyirira chete kuti uwane k-kusazivikanwa mukati me dataset, nepo ichishanda, inogona kuomeswa nenyaya yetsika yekumiririrwa kwakaderera.
