PageRank: Ithiyori yeGrivitational Theory ifakiwe

bekukubi

Ithiyori kaNewton malunga nomxhuzulane ithi amandla aphakathi kwabantu aye ngokulinganayo kwimveliso yezi zimbini kwaye ngokuchaseneyo alingane nesikwere somgama phakathi kwabo bantu:

Amandla omxhuzulane

Ithiyori yeGrivitational ichaziwe:

  1. F bubukhulu bamandla omxhuzulane phakathi kwala manqaku mabini.
  2. G yinto yomxhuzulane.
  3. m1 ubunzima benqaku lokuqala lobunzima.
  4. m2 ubunzima benqaku lesibini ubunzima.
  5. r Umgama phakathi kwezi ngongoma zimbini.

Ithiyori esetyenziswe kwiWebhu:

  1. F bubungakanani bamandla afunekayo ukonyusa isikhundla seinjini yokukhangela.
  2. G i (Google?) rhoqo.
  3. m1 kukuthandwa kwewebhusayithi yakho.
  4. m2 kukuthandwa kwewebhusayithi ofuna ukunxibelelana nayo.
  5. r ngumgama phakathi kokubekwa kweewebhusayithi ezimbini.

Iinjini yokukhangela zibonelela rhoqo ezimisela ubungakanani bemikhosi phakathi kwewebhusayithi ezimbini. Ngokwenza ialgorithm entsonkothileyo ye Iphepha lephepha ebandakanya amakhonkco angasemva, igunya, ukuthandwa kunye nokuqonda kwakhona, iinjini zokukhangela zilawula rhoqo.

Khawufane ucinge uGoogle eyiteleskopu efuna iiplanethi ezinkulu kunye nebhlogosphere ibe yindawo yonke.

Ukubhloga kunye nokuKhangela

Andazi ukuba uLarry Page ('Iphepha' kwiPageRank) kunye noSergey Brin ngenene benze ukufana phakathi kwethiyori kaNewton xa bephuhlisa ii-algorithm ezingundoqo ezazithwelwe Uphando ukuzinza. Ukuqonda lethiyori kunye nokuyisebenzisa kwiwebhu yenye yeendlela zokujonga ukuThengisa iiNjini zokuKhangela, nangona kunjalo. Kananjalo, ndicinga nje ukuba ipholile nje into yokuba ukufana kunokutsalwa.

Ke-ukuba unqwenela ukufumana inqanaba elingcono kwiNjini yokukhangela, eyona nto ukubheja kwakho kukufumana ezinye iisayithi ezikumgangatho ongcono kumagama aphambili afanayo kwaye ubone ukuba ungafumana na ingqalelo. Ukuba bayakunika ingqalelo, amandla asetyenzisiweyo aya kukusondeza kubo. Iiblogi ezinobunzima obukhulu (er… PageRanks) ziyakwazi ukutsala ezinye iisayithi ezincinci ukuba zisondele.

Abathengisi beeNjini zokuKhangela bayayiqonda iTheory

Amakhonkco ahlawulelweyo ngoku athandwa kakhulu kwaye phantsi kohlaselo lukaGoogle. IGoogle ngokubhekisele kumakhonkco ahlawulelweyo njengokuqhuba ngobuchule kweziphumo zophando lwezinto eziphilayo kunye nokutsala iisayithi ukuba, mhlawumbi, azifanelanga. Uninzi lweeblogger (kubandakanya nam) bakubone njengokusebenzisa imali kwigunya labo abalisebenzele nzima.

Phantse yonke imihla ndifumana izibonelelo ezivela kumashishini asemthethweni anqwenela ukusebenzisa indawo yam ukuze isondele. Ndigqibelele ngokukodwa, nangona kunjalo. Ukuza kuthi ga ngoku ndiye ndalahla ngaphezulu kwe- $ 12,000. Oko kunokubonakala ngathi yimali eninzi yokwala, kodwa umngcipheko kukuba ndihenyuza ibhlog yam kwaye uGoogle undiphosa entolongweni (i isalathiso sokuxabisa).

Kumfanekiso omkhulu, andiqinisekanga ukuba Uphando Ungoyisa ikhonkco elihlawulelweyo fiasco. Kubonakala ngathi abanye abantu basebenzisa nje imithetho yomxhuzulane kwaye uGoogle uzama ukulwa nemithetho yendalo.

Abo bafo bakaMicrosoft baqaqambile!

Khange ikhuthaze le posi, kodwa njengoko ndiphanda le post ndiyifumene Microsoft ekhulula Imodeli esekwe kumzabalazo yokufumana ulwazi iphepha ngo-Agasti 2005. Inomdla.
