Kev ntsuam xyuas kev xav yog kev txhais thiab kev faib tawm ntawm kev xav (zoo, tsis zoo thiab nruab nrab) hauv cov ntaub ntawv siv kev txheeb xyuas cov ntawv cov txheej txheem. Kev ntsuam xyuas kev xav tso cai rau cov lag luam los txheeb xyuas cov neeg siv khoom kev xav rau cov khoom, hom lossis cov kev pabcuam hauv kev sib tham hauv online thiab tawm tswv yim.

Tsis tas li ntawd, cov ntaub ntawv kev xav yog dab tsi?

Kev xav tsom xam (tseem hu ua kev xav mining lossis kev xav AI) yog hais txog kev siv cov lus ntuj tsim, kev txheeb xyuas cov ntawv nyeem, suav cov lus piav qhia, thiab biometrics los txheeb xyuas, rho tawm, ntsuas, thiab kawm cov kev cuam tshuam thiab cov ntaub ntawv kawm.

Tom qab ntawd, lo lus nug yog, kev soj ntsuam kev xav hauv tshuab kev kawm yog dab tsi? Kev ntsuam xyuas kev xav yog tus txheej txheem ntawm kev txheeb xyuas thiab txheeb xyuas cov kev xav hauv ib daim ntawv, tshwj xeeb tshaj yog txhawm rau txiav txim siab seb tus kws sau ntawv tus cwj pwm ntawm ib lub ntsiab lus, khoom, thiab lwm yam.

Kuj nug, ua li cas koj ua qhov kev ntsuam xyuas kev xav?

Txawm hais tias koj siv lub cuab yeej twg los ntsuas kev xav, thawj kauj ruam yog nkag mus tweets ntawm Twitter

  1. Kauj ruam 1: Nkag mus Tweets tawm tsam Hash Tags.
  2. Txheeb xyuas Tweets rau Kev Xav.
  3. Kauj Ruam 3: Pom cov txiaj ntsig.
  4. Kauj Ruam 1: Kev cob qhia cov Classifiers.
  5. Kauj ruam 2: Ua ntej Tweets.
  6. Kauj ruam 3: Extract Feature Vectors.

Lub algorithm twg yog siv rau kev soj ntsuam kev xav?

Kev soj ntsuam kev xav yog cov cuab yeej zoo sib xws uas siv los txheeb xyuas cov kev xav ntawm cov neeg siv khoom thiab muaj ntau lub algorithms tuaj yeem siv los tsim cov ntawv thov rau kev soj ntsuam kev xav. Raws li cov neeg tsim khoom thiab cov kws tshaj lij ML SVM , Naive Bayes thiab qhov siab tshaj plaws entropy yog qhov zoo tshaj plaws saib xyuas tshuab kev kawm algorithms.
