4.5.3 Mangani mankhwala anu

Kumanga zokha zanu ndizovuta kwambiri, njira yapamwamba-mphoto. Koma, ngati izo zikugwira ntchito, mukhoza kupindula ndi ndondomeko yabwino yowunikira zomwe zimapangitsa kufufuza kosiyana.

Pomwe mukuyesa kumangodzipangira nokha, ofufuza ena amadzipangira zokhazokha. Zoterezi zimakopa ogwiritsa ntchito ndipo zimakhala ngati nsanja za kuyesayesa ndi kafukufuku wina. Mwachitsanzo, gulu la ochita kafukufuku ku yunivesite ya Minnesota linapanga MovieLens, yomwe imapereka mafilimu aumwini osasamala, omwe siwamagulu. MovieLens yakhala ikugwira ntchito mosalekeza kuyambira 1997, ndipo panthawiyi olemba 250,000 olembetsa amapereka mafilimu oposa 20,000 a mafilimu oposa 30,000 (Harper and Konstan 2015) . MovieLens yagwiritsira ntchito gulu lothandizira popanga kafukufuku wochititsa chidwi kuchokera pakuyesera zamagulu a sayansi za zopereka zogulitsa katundu (Beenen et al. 2004; Cosley et al. 2005; Chen et al. 2010; Ren et al. 2012) zovuta zowonongeka muzovomerezeka (Rashid et al. 2002; Drenner et al. 2006; Harper, Sen, and Frankowski 2007; Ekstrand et al. 2015) . Zambiri mwazomwezi sizingatheke popanda ochita kafukufuku omwe ali ndi mphamvu zogwiritsira ntchito mankhwala enieni.

Mwamwayi, kumanga zokolola zanu ndizovuta kwambiri, ndipo muyenera kuganizira izi monga kukhazikitsa kampani yoyamba: yoopsa kwambiri, yopindulitsa kwambiri. Ngati apambana, njirayi imapereka mphamvu zochuluka zomwe zimachokera pakudziyesa nokha ndi zowona ndi ophunzira omwe amachokera kuntchito zomwe zilipo kale. Kuwonjezera apo, njirayi ingathe kukhazikitsa ndondomeko yowonongeka pomwe pali kufufuza komwe kumabweretsa mankhwala abwino omwe amatsogolera kwa ogwiritsa ntchito omwe amatsogolera ochita kafukufuku ambiri ndi zina zotero (chithunzi 4.16). Mwa kuyankhula kwina, kamodzi kokhala ndi ndondomeko yabwino yotsutsa, kufufuza kuyenera kukhala kosavuta komanso kosavuta. Ngakhale kuti njirayi ndi yovuta kwambiri pakalipano, ndikuyembekeza kuti zidzakhala zothandiza ngati teknoloji ikuyenda bwino. Mpaka pomwepo, ngati wofufuza akufuna kulamulira mankhwala, njira yowonjezeratu ndiyo kugwirizanitsa ndi kampani, mutu womwe ndikutsatira.

Chithunzi 4.16: Ngati mutha kumanga zokhazokha, mukhoza kupindula ndi ndondomeko yabwino yowonjezera: kufufuza kumabweretsa mankhwala abwino, omwe amatsogolera kwa ogwiritsa ntchito, omwe amachititsa kufufuza kwambiri. Mitundu ya malingaliro abwino kwambiri ndi ovuta kwambiri kulenga, koma ikhoza kupangitsa kufufuza zomwe sizikanatheka. MovieLens ndi chitsanzo cha pulojekiti yomwe yapambana kupanga kapangidwe kazokambirana (Harper and Konstan 2015) .
