Ibhu engabonakali iphuma ngaphandle futhi ihluke kakhulu kuwebhu ebomvu
Iyini iwebhusayithi engabonakali?
Uyazi ukuthi kunesidingo esikhulu sedatha engasetshenzisiwe ngaphandle kokusesha okuqondile? Igama elithi "iwebhu engabonakali" ngokuyinhloko libhekisela endaweni enkulu yolwazi ukuthi izinjini nezinkomba azikwazi ukufinyelela ngokuqondile, njengezinqolobane zolwazi.
Ngokungafani namakhasi eWebhu ebonakalayo (okungukuthi, iwebhu ongayifinyelela kuzo izinjini nezinkomba), ulwazi olusencwadini yolwazi ngokuvamile alufinyeleleki kuma-spiders we- software nabaqaphi abadala izinkomba zokusesha injini. Abasebenzisi bakwazi ukufinyelela okuningi kwalolu lwazi, kodwa kuphela ngokuseshwa okuqondile okuvula lapho le lwazi ihlala khona.
Yeka ukuthi iBig iyinethiwekhi engabonakali?
I-Web engabonakali ilinganiselwa ukuthi ikhudlwana ngezikhathi eziningana kunokuqukethwe kweWebhu okutholakala nemibuzo ejwayelekile yokusesha injini. Ngokusho kwe-Bright Planet, inhlangano yokucinga ekhethekile kwisizinda sokuqukethwe se-Invisible Web, I-Invisible Web iqukethe cishe ama-550 billion amadokhumenti ngamanye amabhiliyoni weWebhu.
Izinjini ezinkulu zokusesha - i- Google , i-Yahoo, i- Bing - ayibuyiseli konke okufihliwe "okufihliwe" ekusesheni okujwayelekile, ngoba nje abakwazi ukubona lokho okuqukethwe ngaphandle kwemingcele ekhethekile yokusesha kanye / noma ubuchwepheshe bokusesha. Kodwa-ke, uma usesho ekwazi ukuthi angena kanjani le datha, kunezinhlobonhlobo eziningi zolwazi olutholakalayo.
Kungani Kuthiwa & # 34; Iwebhu Engabonakali & # 34 ;?
Izigaxekile, eziyizinhlelo ezincane zesofthiwe, zihamba ngewebhu, zikhomba amakheli wamakhasi athola. Uma lezi zinhlelo ze-software zingena ekhasini elivela kwi-Invisible Web, azi ukuthi yini okufanele zenze ngayo. Lezi zikhawu zikwazi ukurekhoda ikheli, kodwa azikwazi ukufinyelela lutho mayelana nolwazi oluqukethwe ikhasi.
Kungani? Kunezici eziningi, kodwa ikakhulukazi ziphelela ezithintelweni zobuchwepheshe kanye / noma izinqumo ezizibophezelayo engxenyeni yomnikazi wendawo (s) ukukhipha amakhasi abo kusuka ezihlakalweni zenjini yokusesha. Isibonelo, iziteyibhrari zamayunivesithi ezidinga amaphasiwedi ukufinyelela ulwazi lwazo ngeke zifakwe kwimiphumela ye-injini yokusesha, kanye namakhasi asekelwe kwiskripthi engafundwa kalula yizicabucabu zenjini yokusesha.
Kungani I-Web Engabonakali Kubalulekile?
Abasebenzisi abaningi bakholelwa ukuthi kungase kube lula ukunamathela kokungatholakala nge-Google noma ku-Yahoo. Kodwa-ke, akulula ngaso sonke isikhathi ukuthola ukuthi yini oyifunayo nge injini yokusesha, ikakhulukazi uma ufuna into encane noma engacacile.
Cabanga ngeWebhu njengomtapo omkhulu. Iningi labantu lingenakulindela ukuhamba nje emnyango wangaphambili futhi ngokushesha uthole ulwazi emlandweni wevidyo zevidyo ezisempumalanga; babengalindela ukulimba. Yilapho izinjini zokusesha ngeke zikusize kodwa i-Web engabonakali iyothatha.
Iqiniso lokuthi izinjini zosesho zifuna kuphela ingxenye encane kakhulu yewebhu zenza iWebvisi Engabonakali ibe yimithombo enzima kakhulu. Kunolwazi oluthe xaxa ngaphandle lapho singacabanga khona.
Ngisebenzisa kanjani i-Invisible Web?
Kukhona abanye abantu abaningi abazibuze wona umbuzo ofanayo, futhi bahlanganise izindawo ezinhle ezisebenzayo njengengxenye yokuqalisa ku-Invisible Web. Nazi ezinye zezindlela ezihlukahlukene:
Abantu
- Izwi le-Shuttle: Kwaqala ngo-1994, i-VoS ingenye yezindala zokudala ezisebuntwini ezidala kunazo zonke futhi ezikhulu kunabo bonke kwiWebhu, zinikeza inkomba ekhethekile yokuqukethwe kwesifundo esivela ku-Anthropology kuya kwi-Technology of Writing.
Ngokuqondile kuhulumeni wase-US
- IYunivesithi yaseMichigan Amadokhumenti kaHulumeni Isikhungo: Uzothola imibiko, izibalo, neminye imibhalo evela kuwo wonke amazinga ohulumeni wase-US lapha. Ulwazi olunikezwa luhlanganisa Arts, Health Sciences, Social Sciences, kanye International Studies.
- I-USA.gov: Ingosi ebomvu yamaphepheni ekujuleni kwezinhlangano eziningi zikahulumeni wase-United States. Kufaka phakathi imisebenzi kahulumeni, uhlu lwe-A kuya Z lwama-ejensi kahulumeni, nolwazi lokuthola izibonelelo, ukuboleka imali nokusiza ngezezimali.
Ezempilo neSayensi
- I-PsycNET: Sebenzisa lolu datha kusuka e-American Psychological Association ukuthola izinhlamvu kanye namaphephandaba onke ngezihloko ezihlukahlukene zengqondo (izimali ziyasebenza ekufakweni kwamaphephandaba agcwele, izikhala ngokuvamile zikhululekile).
- I-Healthfinder: Ulwazi oluhloswe ngalo oluvela kulwazi olungaphezu kwezinkulungwane ezihlukene zezempilo kuWebhu. Izinsiza eziningi ezihlukahlukene ezihlokweni zempilo ezithokozayo ziyatholakala lapha.
- I-RXList: Uma ufuna ukwaziswa okunokwethenjelwa kwezidakamizwa, khona-ke le databases yezidakamizwa zemithi, imithi, kanye namakhophi we-pilill akuwe. Inikeza iqoqo le-A kuya ku-Z, izithombe zokuqoqa, nesichazamazwi semigomo.
I-Mega-Portals
- I-Library ye-Virtual ilula futhi isebenziseka kalula, ngezixhumanisi zezihloko ezichaziwe. Ngiyawazisa ngokukhethekile izichasiselo ngoba kusiza ukukhipha isikhathi sokusesha esikude.
Kuthiwani Ngenye Imithombo Yewebhu Engabonakali?
Kukhona amasayithi amaningi, asetshenziselwa ukumba ku-Invisible Web. Ulwazi oluningi lweWebhu engabonakali lugcinwa yizikhungo zezemfundo, futhi linomgangatho ophakeme kunemiphumela yosesho. Kukhona "izindlela zokufunda" ezingakusiza ukuthi uthole lolu lwazi. Ukuze uthole cishe noma iyiphi imithombo yezemfundo kwiWebhu, mane uthayiphe kulolu chungechunge lokusesha enjini yakho yokusesha oyintandokazi:
isayithi: .edu "isihloko engiyifunayo"
Usesho lwakho luzobuyela kanye namasayithi ahlobene nathi. Uma unesikolweni esithile engqondweni ongathanda ukukusesha, sebenzisa i- URL yesikole ekusesheni kwakho:
isayithi: www.school.edu "isihloko engiyifunayo"
Hlela isihloko sakho ngaphakathi kwezingcaphuno uma kungaphezu kwamagama amabili; lokhu kwenza injini yokusesha oyisebenzisayo yazi ukuthi ufuna ukuthola lawo magama amabili eduze komunye nomunye. Funda kabanzi mayelana namasu wokusesha ukuze ube nolwazi oluningi ekusesheni kwakho kuwebhu.
Okubalulekile Nge-Web Engabonakali
I-Web engabonakali inikeza izinsiza eziningi kunoma yini ongase ucabange ngayo. Izixhumanisi ezigqanyisiwe kulesi sihloko zivele ziqale ukuthinta izinsiza ezinkulu ezitholakalayo kwi-Invisible Web. Njengoba isikhathi siqhubeka, i-Invisible Web izobe ikhudlwana, futhi yingakho kungumqondo omuhle ukuthi ufunde ukuyihlola manje.
