Abstrakt<\/h5>\n

V d\u00f4sledku zmien spotrebite\u013esk\u00e9ho spr\u00e1vania sa spotrebite\u013e orientuje viac na n\u00e1kup cez internet. \u0160tatistick\u00e9 in\u0161tit\u00facie zodpovedn\u00e9 za zber cien tovarov a slu\u017eieb s\u00fa n\u00faten\u00e9 prehodnoti\u0165 tradi\u010dn\u00fd zber cien pre oblas\u0165 cenovej \u0161tatistiky a v niektor\u00fdch pr\u00edpadoch ho potenci\u00e1lne nahradi\u0165 automatick\u00fdm zberom cien cez internet, tzv. webscrapingom. Implement\u00e1cia tak\u00e9hoto zdroja \u00fadajov prin\u00e1\u0161a so sebou r\u00f4zne v\u00fdzvy, od ot\u00e1zok v metodickej oblasti a\u017e po v\u00fdznamn\u00fa zmenu procesov spracovania \u00fadajov. Ide o spracovanie ve\u013ek\u00e9ho mno\u017estvo \u00fadajov, vr\u00e1tane hodnotenia ich kvality, v\u00fdberu reprezentantov a ur\u010denie cien jednotliv\u00fdch tovarov, ktor\u00e9 s\u00fa obvykle scrapovan\u00e9 na dennej b\u00e1ze. \u010eal\u0161ou v\u00fdzvou je v\u00fdber met\u00f3dy na v\u00fdpo\u010det indexu spotrebite\u013esk\u00fdch cien, ktor\u00e1 sa m\u00f4\u017ee z\u00e1sadne odli\u0161ova\u0165 od met\u00f3dy v\u00fdpo\u010dtu indexu spotrebite\u013esk\u00fdch cien pou\u017eitej pri tradi\u010dnom zbere \u00fadajov. Cie\u013eom tohto \u010dl\u00e1nku je predstavi\u0165 teoretick\u00fd r\u00e1mec na implement\u00e1ciu webscrapovan\u00fdch \u00fadajov do produkcie cenov\u00fdch \u0161tatist\u00edk. V pr\u00edpadovej \u0161t\u00fadii sme pou\u017eili \u00fadaje o cen\u00e1ch pre produktov\u00fa skupinu chladni\u010dky, ktor\u00e9 boli scrapovan\u00e9 z webov\u00e9ho porovn\u00e1vacieho port\u00e1lu www.heureka.sk.<\/p>\n
