3 verschillende webschrapende manieren van Semalt

Het belang en de noodzaak van het extraheren of schrapen van gegevens van de websites zijn geworden steeds populairder met de tijd. Vaak is het nodig om gegevens uit zowel basis- als geavanceerde websites te extraheren. Soms halen we handmatig gegevens uit, en soms moeten we een tool gebruiken, omdat handmatige gegevensextractie niet de gewenste en nauwkeurige resultaten oplevert.

Of u nu bezorgd bent over de reputatie van uw bedrijf of merk, de online chatters rondom uw bedrijf wilt volgen, onderzoek moet uitvoeren of een vinger aan de pols moet houden van een bepaalde industrie of product, moet u altijd gegevens schrapen en deze van niet-georganiseerde vorm naar de gestructureerde versie omzetten.

Hier moeten we drie verschillende manieren bespreken om gegevens uit het web te halen.

1. Bouw uw persoonlijke crawler.

2. Gebruik de krabbels.

3. Gebruik de voorverpakte gegevens.

1. Bouw je crawler:

De eerste en bekendste manier om gegevens te extraheren is om je crawler te bouwen. Hiervoor moet je een aantal programmeertalen leren en moet je de technische details van de taak goed in de gaten houden. Je hebt ook een schaalbare en behendige server nodig om de gegevens of webinhoud op te slaan en te openen. Een van de belangrijkste voordelen van deze methode is dat de crawlers volgens uw vereisten worden aangepast, waardoor u volledige controle hebt over het proces voor gegevensextractie. Het betekent dat u krijgt wat u echt wilt en dat u gegevens kunt schrapen van zoveel webpagina's als u wilt zonder u zorgen te hoeven maken over het budget.

2. Gebruik de Data Extractors of Scraping Tools:

Als je een professionele blogger, programmeur of webmaster bent, heb je misschien geen tijd om je scraping-programma te bouwen. In dergelijke omstandigheden moet u de reeds bestaande datatextractors of scraptools gebruiken. Import.io, Diffbot, Mozenda en Kapow zijn enkele van de beste tools voor het opschalen van webgegevens op internet. Ze komen beide in gratis en betaalde versies, waardoor je gemakkelijk gegevens van je favoriete sites kunt scrapen. Het belangrijkste voordeel van het gebruik van de hulpprogramma's is dat ze niet alleen gegevens voor u extraheren, maar deze ook organiseren en structureren, afhankelijk van uw vereisten en verwachtingen. Het kost u niet veel tijd om deze programma's in te stellen en u krijgt altijd de juiste en betrouwbare resultaten. Bovendien zijn de tools voor webscraping goed als we te maken hebben met de eindige set van resources en de kwaliteit van data tijdens het hele scrapingproces willen controleren. Het is geschikt voor zowel studenten als onderzoekers en deze hulpmiddelen zullen hen helpen online onderzoek naar behoren uit te voeren.

3. Voorverpakte gegevens van het Webhose.io-platform:

Het Webhose.io-platform biedt ons toegang tot goed geëxtraheerde en bruikbare gegevens. Met de DaaS-oplossing (Data-as-a-Service) hoeft u uw webscraping-programma's niet in te stellen of te onderhouden en kunt u gemakkelijk vooraf gecrawlde en gestructureerde gegevens ontvangen. Het enige wat we moeten doen is de gegevens filteren met behulp van de API's, zodat we de meest relevante en juiste informatie krijgen. Vanaf vorig jaar hebben we ook toegang tot de historische webgegevens met deze methode. Het betekent dat als iets eerder verloren was gegaan, we er toegang toe zouden hebben in de map Achieve van Webhose.io.
