Semalt: Web Data Extraction With Extension

Informatie extraheren van krachtige websites gebouwd met de moderne technologieën zoals JavaScript is nog nooit zo eenvoudig geweest. Webscraping omvat het extraheren van grote hoeveelheden gegevens zonder de Application Programming Interface (API) te definiëren.

Voor beginners  is de techniek van webscraping  vooral gericht op het extraheren van ongestructureerde en semi-gestructureerde gegevens op webpagina's en sites naar gestructureerde gegevens die later worden opgeslagen in Excel-spreadsheets en databases. Tegenwoordig is scrapen een doe-het-zelf-taak, dankzij Google. Met de webschraperextensie is het schrapen van het web slechts een klik verwijderd.

Ongestructureerde gegevens zijn meestal beschikbaar in HTML-indeling. Om de gegevens van websites in eenvoudige vormen op te halen, moet u wat schrapen. Als coderen niet uw interesse is, is de webschraperextensie ontworpen om tegemoet te komen aan uw behoeften op het gebied van webgegevensextractie.

Online prijsvergelijking

Web scraper extension haalt nuttige informatie uit online winkels zoals afbeeldingen, productprijzen en beschrijving. De informatie wordt gebruikt door eigenaren van e-business voor prijsvergelijking en data-analyse. Schrapen wordt ook veel gebruikt door online reisbureaus. Met een extensie voor een webschraper kunt u eenvoudig afbeeldingen en productprijzen extraheren van meerdere sites en de gegevens opslaan in gegevensbladen voor gegevensanalyse.

Beheer van online reputatie

In de wereld van online marketing is het handhaven van uw online status even essentieel als het opnieuw bezoeken van uw marketingstrategieën. Dit is waar veel e-bedrijven het mis hebben. Geld besteed aan online reputatiemanagement gaat niet verloren. Met webschrapen kunt u nuttige gegevens extraheren over trending-problemen, meningen van klanten en demografische feiten.

Met dit type gegevens op uw Excel-sheets kunt u beslissen welke gebieden van invloed zijn op het vergroten van uw merkpopulariteit en het voorkomen van reputatieschade in realtime.

Wijzigingen in de website en spambeschrijvingen detecteren

Website-indelingen veranderen van de ene dag op de andere. Het is daarom van essentieel belang wijzigingen in de lay-out in realtime te noteren en effectieve strategieën te implementeren voor het verkrijgen van bruikbare gegevens. Hier komt de webschraperuitbreiding binnen. Met deze browserextensie kunt u websitewijzigingen en frauduleuze revisies detecteren die erop gericht zijn uw potentiële gebruikers te misleiden.

Waarom Web Scraper?

Web Scraper is een browser-plug-in die op het hoogste niveau staat en die extractiediensten en Google Chrome-extensie gratis biedt. Gegevens die door Web Scraper zijn geëxtraheerd, worden gedownload in CSV-bestandsindeling en later opgeslagen in CouchDB. Web scraping-activiteiten zoals data-extractie, export en sitemap-opbouw worden uitgevoerd in de Chrome-browser.

Wat is een webschraperuitbreiding?

Web Scraper is een plug-in of een extensie die gratis wordt aangeboden in de Google-webwinkel. Met deze extensie kunt u nuttige gegevens uit krachtige webpagina's extraheren. Gegevens die met de webschraperuitbreiding zijn opgehaald, kunnen worden opgeslagen als CSV-bestand of in CouchDB. Deze extensie werkt vanaf het begin in een sitemap. Als gebruiker moet je beslissen wat je uitpakt en wat je achter moet laten.

Om Web Scraper te installeren, bezoekt u de Google-webwinkel en voegt u de extensie toe aan Chrome. Laat Web Scraper Extension het schrapen voor je doen. Deze plug-in navigeert en extraheert de gegevens volgens de sitemap-build van de eindgebruiker.
