Semalt Expert: Die besten Website-Schaber, um Daten aus dem Web zu erfassen

Jan 23, 2018

Wenn Sie versuchen, eine scraper.com-Abfrage in Ihrem Browser am häufigsten einzugeben Wahrscheinlich suchen Sie nach einem geeigneten Web-Scraper, um die Daten aus dem Netz zu extrahieren. Es gibt jedoch effizientere Möglichkeiten, um Inhalte zu erhalten, die Sie benötigen, und wir stellen Ihnen alle vor.

Seit das Internet hinsichtlich Datengröße und -qualität zu wachsen begann, suchten die Datenwissenschaftler und Programmierer nach neuen Website-Scraping-Diensten. Sie können Daten entweder manuell aus dem Internet scratchen (das ist nur möglich, wenn Sie Python, PHP, JavaScript, C ++, Ruby und andere Programmiersprachen erlernt haben) oder Sie können einen Website-Scraper verwenden, um Ihre Aufgaben zu erledigen.

Die zweite Option ist besser als die erste, da ein Scraper die Rohdaten in eine strukturierte und organisierte Form umwandeln kann und keine Codezeile benötigt.

1. ParseHub

Mit ParseHub können Sie problemlos mehr als 1.000 URLs gleichzeitig scrappen. Dieses Tool ist sowohl für Programmierer als auch für Nicht-Programmierer geeignet und extrahiert Daten von mehrsprachigen Sites. Es verwendet bestimmte APIs, um mit wenigen Klicks Hunderte bis Tausende von Keywords zu finden. Mit diesem Schaber kannst du alle auf YouTube verfügbaren Videos durchsuchen und sie gleichzeitig anvisieren.

2. CloudScrape (auch bekannt als Dexi.io)

CloudScrape ist eines der besten und bekanntesten Schabwerkzeuge. Es navigiert durch verschiedene Webseiten, sammelt Daten, kratzt es und lädt sich einfach auf Ihre Festplatte..Es ist eine Browser-basierte Web-Anwendung, die zahlreiche Daten-Scraping-Aufgaben für Sie erledigen kann.

Sie können die extrahierten Daten direkt auf Google Drive und Box.net speichern. Alternativ können Sie es in CSV- und JSON-Formate exportieren. Dexi.io ist bekannt für seine anonymen Datenextraktionseigenschaften und bietet verschiedene Proxy-Server, um Ihre Anforderungen zu erfüllen. Sie können mit diesem Tool sofort bis zu 200 URLs scrappen.

3. Scraper

Es ist eine Chrome-Erweiterung mit unbegrenzten Datenextraktionseigenschaften. Mit Scraper können Sie auf einfache Weise Informationen von einer dynamischen Website extrahieren, Online-Recherchen durchführen und die Daten in Google-Tabellen exportieren. Dieses Programm eignet sich für Freelancer, App-Entwickler, Programmierer und Nicht-Programmierer. Scraper ist eine Freeware, die direkt in Ihrem Webbrowser funktioniert und winzige XPaths generiert. Es definiert Ihre Webinhalte besser und hilft beim Crawlen Ihrer Webseiten. Sie müssen die unordentliche Konfiguration nicht angehen, und die Eigenschaften und Funktionen dieses Tools sind denen von ParseHub ähnlich.

4. Scrapinghub

Scrapinghub ist eines der besten Scraping-Tools im Netz und hilft, wertvolle Daten zu gewinnen, indem ein spezieller Proxy-Rotator zur Ausführung seiner Aufgaben verwendet wird. Scrapinghub ist am besten für seine benutzerfreundliche Oberfläche bekannt und verwendet Bots zum Crawlen verschiedener Webseiten. Es bietet seinen Nutzern vollständigen Spamschutz und extrahiert mit wenigen Klicks Daten aus der gesamten Website.

5. VisualScraper

VisualScraper ist genau wie ParseHub und Scrapinghub ein leistungsstarker, zuverlässiger und authentischer Web-Scraper. Mit diesem Tool können Sie Daten aus über 2000 URLs gleichzeitig extrahieren. Die Software hilft dabei, Informationen aus mehreren Blogs und Websites zu sammeln und das Ergebnis in Echtzeit abzurufen. Sie können VisualScraper auch verwenden, um Informationen aus PDF-Dokumenten, JPG- und PNG-Dateien sowie HTML-Dokumenten zu extrahieren. Sobald die Daten gescratet sind, können Sie sie in Formate wie SQL, JSON, CSV und XML exportieren. VisualScraper ist mit verschiedenen Webbrowsern und Betriebssystemen kompatibel und ist hauptsächlich für Windows- und Linux-Benutzer verfügbar.
