Nws nyuaj rau tus neeg niaj hnub xav txog lub neej yam tsis muaj Is Taws Nem thiab yuav luag tam sim ntawd nkag mus rau cov ntaub ntawv xov xwm. Tus neeg siv tsis tshua xav txog yuav ua li cas tshawb nrhiav cov ntsiab lus xav tau ntawm lub network tau ua tiav. Tab sis qhov no nthuav heev.

Cov ntaub ntawv khaws cia (IPS) yog qhov nyuaj software thiab kho vajtse uas xaiv cov ntaub ntawv ntawm tus neeg siv qhov kev thov. Cov ntaub ntawv khaws cia ntawm cov servers hauv daim ntawv digital, raws li cov phau ntawv siv los nyob rau ntawm cov tsev qiv ntawv. Lub system muaj ntau subsystems. Txhua tus ua nws txoj haujlwm nyob rau hauv tus txheej txheem ntawm kev ua tus neeg siv qhov kev thov thiab muab cov ntaub ntawv rau nws nyob rau hauv cov ntawv nyeem los yog suab daim ntawv. Qhov ntau ntawm cov dej num yuav daws tau txiav txim siab qhov nyuaj ntawm cov qauv ntawm cov ntaub ntawv niaj hnub retrieval systems (ib qho luv luv ntawm cov ntaub ntawv retrieval system). Ib hom "black box": ntawm cov tswv yim - cov ntawv thov, dab tsi yog sab hauv - tsis paub, ntawm cov zis - cov ntaub ntawv qhia meej.

Input streams

Thov kom paub cov ntaub ntawv uas tus neeg sau ntawv hauv daim ntawv ntawm lub vijtsam ntawm nws lub cuab yeej,ua ib feem me me ntawm qhov kev thov ua tiav los ntawm lub tshuab tshawb nrhiav. Cov ntsiab lus tseem ceeb ntawm cov lus nug tshawb fawb yog tsim los ntawm cov neeg hlau uas lees txais tib neeg thov thiab ua ntau kauj ruam tshawb nrhiav thiab tawm tswv yim nrog tus neeg siv. Cov ntaub ntawv retrieval systems suav nrog Google paub zoo, Yandex thiab lwm tus, ua ntau lab thov txhua hnub.

Neeg nrhiav khoom

Cov khoom pib ntawm kev txaus siab rau kev tshawb fawb yog cov ntaub ntawv, cov ntaub ntawv, cov yeeb yaj kiab, duab thiab ntau dua. Lawv raug tsim tawm sab nraum IPS. Cov ntaub ntawv dav dav khaws cia thiab khaws cov ntaub ntawv yuav tsum muaj cov kab ntawv sau ua ke - ib hom ntawv teev cia uas tso cai rau koj tshawb nrhiav txhua yam khoom.

Cov khoom lossis lawv cov kev hloov pauv digital dhau los ua "cov peev txheej nkag" rau hauv IPS. Nws yog ntawm lawv cov ntaub ntawv uas tus neeg siv xav tau raug xaiv.

External sources

Kev xaiv cov ntaub ntawv saib siv cov kev paub sab nraud. Nov yog cov ntaub ntawv uas tus neeg siv tab tom nrhiav. Lub npe ntawm cov yeeb yaj kiab, nqe lus los ntawm phau ntawv, thiab lwm yam. Rau kev tshawb nrhiav hauv computer, cov ntaub ntawv no yuav tsum tau muab txhais ua cov lus nug hauv cov lus algorithmic. Hauv IPS, qhov no yog ua tiav siv qhov thaiv los tsim, indexing thiab tsim cov lus nug.

Qhov zoo tshaj plaws, peb cov txheej txheem no - kev sawv cev, kev txheeb xyuas, thiab kev nug kev txhim kho - yuav tsum vam khom cov kev paub zoo ib yam, tab sis hauv kev xyaum, qhov no tsis tuaj yeem ua tiav.

Cov peev txheej kev paub yuav tsum tau tshuaj xyuas tas li thiab hloov kho, thiab qhov hloov tshiab yuav tsum zoo ib yam thiabsynchronized. Thiab ib qho chaw sab nraud ntawm kev paub ib txwm ua raws sijhawm ua ntej nws siv hauv kev tshawb fawb xyaw rau cov lus nug, qee zaum los ntawm ntau xyoo.

Kev ua haujlwm

Cov lus sawv cev ntawm cov khoom qub yog tsim los ntawm cov ntaub ntawv tawm tswv yim hauv qee qhov sib xyaw lossis hloov pauv raws li cov cai thiab cov txheej txheem ntawm cov ntaub ntawv tshwj xeeb retrieval system.

Views yog ntau dua lossis tsawg dua cov ntawv luam ntawm cov khoom tshawb nrhiav thawj zaug. Hauv kev sau ntawm cov ntawv uas tsis tau hloov kho, txhua phau ntawv yog nws tus kheej sawv cev. Hauv kev sau cov khoom ntawm cov khoom pov thawj thiab cov khoom qub, cov neeg sawv cev tuaj yeem hloov pauv cov lus piav qhia ntawm cov khoom nrog nws cov duab. Qee qhov xwm txheej, cov neeg sawv cev tuaj yeem yog ib feem los ntawm cov khoom qub thiab ib feem los ntawm cov lus piav qhia: hauv phau ntawv tshawb fawb xyaw, cov lus sawv cev tau muab los ntawm cov khoom - piv txwv li, lub npe, tus sau lub npe yuav muab ua ke nrog cov lus piav qhia ntawm txoj haujlwm.

Searchable index

Vim cov ntaub ntawv hauv cov ntaub ntawv khaws cia hauv daim ntawv sawv cev, nws yog qhov tsim nyog xav tias kev tshawb nrhiav tau ua raws li tus sawv cev thiab, tom qab xaiv, muab rau tus neeg siv. Hauv kev xyaum, qhov no tsis yog li ntawd. Piv txwv li, cov tsev qiv ntawv hauv online tam sim no feem ntau txwv kev tshawb nrhiav rau ob peb lub teb: tus sau, npe, thiab cov ntawv sau npe hauv ib qho kev pom uas muaj lwm qhov chaw uas tsis tau tshawb nrhiav. Qhov no yog qhov laj thawj txaus vim li cas thiaj li yuav tsum paub qhov txawvib qho kev pom thiab qhov ntsuas tau tshawb nrhiav, uas yog qhov kev tshawb nrhiav ntawm qhov pom. Nws txhais txhua yam uas yuav tsum tau tshawb nrhiav. Ib qho kev tshawb nrhiav tau, zoo li qhov pom thiab qhov khoom, tuaj yeem muab faib ua cov sub-indexes cais kom muab qhov tseeb dua, tsom rau kev tshawb nrhiav

Tshawb nrhiav cav feem ntau muaj cov qauv hluavtaws sab hauv kom sib piv cov txiaj ntsig kev tshawb fawb. Cov qauv no yog qhov thib ob ntawm kev tshawb nrhiav qhov ntsuas.

Txheej txheem, txheej txheem indexing tuaj yeem siv ntau txoj hauv kev: kev tshawb nrhiav tau los ntawm:

• sau ntawv luam ib tus sawv cev tshawb nrhiav;
• los ntawm luam cov ntsiab lus saib. Qhov no tej zaum yuav yog ib feem lossis tag nrho cov kev xav uas lub cev muaj tsuas yog cov khoom tawg, muab faib raws li cov cai los tsim qhov ntsuas rau kev tshawb nrhiav, uas yuav raug sau thaum tsim nyog.

Thov tsim cov cai thiab thov raug cai

Kev nug engineering yog lub luag haujlwm uas sib kho ntawm tus neeg siv cov lus nug thiab cov lus nug raug cai. Nws hloov pauv tus neeg siv cov lus nug, sib piv nrog cov lus txib kom rov qab tau, cov lus qhia tshwj xeeb, thiab qhov ntsuas ua ntej muab rov qab. Thaum kaj ntug ntawm txoj kev loj hlob ntawm IPS, lub luag haujlwm no ib txwm muab rau cov kws tshaj lij IT uas tsim nyog.

Tsim cov lus nug hauv computer uas tuaj yeem phim cov lus nug hauv phau ntawv txhais lus rau hauv qhov kev tshawb nrhiav qhov ntsuas tau feem ntau hu ua "dictionary input" module. Automation ntawm txoj haujlwm no tau cog lus tseg thiab muaj sijhawm rau cov kws tshaj lij thiab cov kev tshawb nrhiav qhov tshwm sim.

Ib daim ntawv thov yuav dhau los ua kev thov tom qab tus neeg siv qhov kev thov tau hloov dua siab tshiab. Piv txwv ntawm cov kev hloov pauv xws li truncation, hloov pauv, normalization, vectorization thiab lwm yam kev hloov pauv ntawm "sab nraud" sawv cev rau hauv "sab hauv" sawv cev ntawm computer IPS (decryption - cov ntaub ntawv rov qab qhov system).

Extracted Document Link Sets

Cov txiaj ntsig ntawm cov ntaub ntawv tau txais txiaj ntsig yog qhov muaj txiaj ntsig ntawm cov kev xav tau tsim los ntawm cov kev cai sib txuam siv rau cov lus nug raug cai los ntawm kev tshawb nrhiav tau.

Feem ntau, tab sis tsis tas yuav tsum, muaj cov txheej txheem cais cais rau cov ntaub ntawv rov qab. Cov tsev qiv ntawv hauv online feem ntau rov xaj tau txais cov ntawv sau los ntawm tus sau ua ntej tso tawm. Nyob rau hauv cov ntaub ntawv retrieval systems uas tsim nruj rankings, ranking order precedes ib reordering.

tawm kwj

Cov txiaj ntsig ntawm kev tshawb fawb tau ua tiav ib txwm ua rau ntawm cov zaub, ntau zaus hauv daim ntawv kwj ntawm cov khoom siv rau lwm qhov lossis rau qee lub hom phiaj, ua tiav qhov kev tshawb nrhiav lub ntsiab. Cov kwj no tuaj yeem xa mus rau cov khoom siv pom., cia rau kev ua haujlwm ntxiv, lossis siv los ua cov dej nkag rau lwm qhov kev xaiv.

Cov ntaub ntawv rov qab cov tshuab tso cai tawm tswv yim los ntawmcov zis ntawm tej txheej txheem xaiv. Cov zis ntawm txhua tus txheej txheem tuaj yeem yog cov lus teb rau lwm cov txheej txheem. Cov lus teb tuaj yeem muab lub hauv paus rau cov kws tshaj lij txiav txim siab ntawm txhua theem.
