Semalt Expert: Regular Parsing Vs. Web Data Scraping

Data scraping (of data-extractie) is een techniek die door marketeers wordt gebruikt om haal gegevens uit e-commerce websites. De gegevens worden later opgeslagen in een database of in uw lokale registerbestanden. De overdracht van gegevens omvat het gebruik van protocollen en datastructuren. In de moderne marketingwereld gebruiken digitale marketeers een datacrawler-tool om gegevens en inhoud van websites te krijgen.

Gegevensschrapen worden gewoonlijk door marketeers gebruikt om te winkelen, prijzen te vergelijken en bedrijfsonderzoek uit te voeren. In de meeste gevallen gaat data scraping gepaard met geautomatiseerde scripts en indelingen, waardoor het voor een mens moeilijk wordt om de bestanden te lezen. Een tool voor gegevensschrapers negeert multimedia-informatie, afbeeldingen en commentaren die de geautomatiseerde verwerking van gegevens kunnen belemmeren.

Hoe gegevensschrapen werkt

Gegevensschrappen biedt marketeers de gelegenheid hun onderzoek te bespoedigen. Het ophalen van gegevens van een enkele website is een doe-het-zelf-taak waarvoor geen training vereist is. Als u werkt aan het ophalen van veel gegevens met behulp van protocollen en indelingen, overweeg dan om een dataschraper een opname te geven. Het verzamelen van verschillende versies van gegevens uit een enkele bron is gewoon geweldig.

Met gegevensschrapen kunnen marketeers ongestructureerde gegevens uit meer dan één bron halen en de bestanden in één database ordenen. Een tool voor gegevensschrapen wordt veel gebruikt door marketeers om gegevens te verzamelen van een systeem dat geen compatibiliteits- en toegankelijkheidsfuncties heeft. Het apparaat wordt ook veel gebruikt in e-commerce websites die geen toegankelijke Application Programming Interface (API) bieden. Sommige sites beschouwen schermschrapen echter als illegaal vanwege het toegenomen verlies van advertentie-inkomsten..

Sommige starters hebben enkele vragen gesteld om onderscheid te maken tussen gepaste parsing en gegevensschraping. Data scraping impliceert het negeren van commentaren. De uitvoergegevens die resulteren uit schrapen zijn altijd bedoeld voor potentiële eindgebruikers. Bij regelmatig parseren zijn de gegevens noch goed gedocumenteerd, noch gestructureerd.

Wat is schermschrapen?

Screenscraping omvat de extractie van visuele gegevens en een fronsen van een website. Schermschrapen houdt in dat de terminal-invoerpoort op de ene computer en de uitvoerpoort op een andere worden aangesloten om gemakkelijk gegevens te kunnen lezen. Een schermschraper werkt met betrekking tot een oud framework via Telnet en navigeert een oude interface om de juiste soort gegevens te extraheren.

Nuttige informatie over webschrapen

Wat webschrapen betreft, worden nuttige inhoud en gegevens gewoonlijk opgeslagen in de vorm van XHTML- en HTML-talen. Toolkits werden ontwikkeld en ontworpen om door de mens leesbare gegevens te trekken. Een datacrawler-tool werkt aan het extraheren van essentiële gegevens van e-commerce websites zoals Google en Amazon. De moderne vormen van webschrapen omvatten de evaluatie van datafeeds die afkomstig zijn van servers. Tegenwoordig initiëren e-commerce websites defensieve algoritmen op hun systemen om te voorkomen dat een datacrawler-tool gegevens van hun sites haalt.

Report mining

Report mining omvat het verwijderen van gegevens uit statistieken van door mensen leesbare machines. Rapportmining minimaliseert potentiële licentiekosten voor eindgebruikers die van toepassing zijn op klanten voor Enterprise Resource Planning. Rapportmining bestaat uit het gebruik van indelingen zoals PDF, tekst en HTML.

Gegevensschrapen omvat het verzamelen van verschillende gegevensvormen in één registerbestand. Een tool voor gegevensschraper helpt marketeers om hun onderzoek te versnellen en de betrokkenheid van gebruikers te vergroten. Gebruik gegevensschrapen om verkoopleads te vinden en gegevens uit meerdere bronnen voor uw website op te halen.
