Esperto di Semalt: i migliori scrapers del sito Web per acquisire dati dal Web

Feb 07, 2018

Se si sta tentando di digitare una query di scrapper.com nel proprio browser, la maggior parte probabilmente stai cercando un vero web raschietto per estrarre i dati dalla rete. Tuttavia, ci sono modi più efficienti per ottenere qualsiasi contenuto di cui hai bisogno e noi ti presenteremo tutti loro.

Da quando Internet ha iniziato a crescere in termini di dimensioni e qualità dei dati, i ricercatori e i programmatori di dati hanno iniziato a cercare nuovi servizi di scraping per i siti Web. Puoi raschiare manualmente i dati da Internet (ciò è possibile solo quando hai imparato Python, PHP, JavaScript, C ++, Ruby e altri linguaggi di programmazione) o puoi utilizzare un raschietto per siti web per portare a termine le tue attività.

La seconda opzione è migliore della prima perché un raschietto può trasformare i dati grezzi in una forma strutturata e organizzata e non richiede una riga di codice.

1. ParseHub

Con ParseHub, puoi facilmente racimolare più di 1.000 URL alla volta. Questo strumento è adatto sia per programmatori che per non programmatori ed estrae dati da siti multilingue. Utilizza API specifiche per aiutarti a trovare da centinaia a migliaia di parole chiave con pochi clic. Con questo raschietto, puoi cercare tutti i video disponibili su YouTube e selezionarli contemporaneamente.

2. CloudScrape (noto anche come Dexi.io)

CloudScrape è uno dei migliori e più famosi strumenti di scraping web. Naviga attraverso diverse pagine Web, raccoglie dati, li ritira e li scarica facilmente sul tuo disco rigido. È un'applicazione web basata su browser che può eseguire numerose attività di scraping dei dati per te.

È possibile salvare direttamente i dati estratti su Google Drive e Box.net. In alternativa, puoi esportarlo nei formati CSV e JSON. Dexi.io è meglio conosciuto per le sue proprietà anonime di estrazione dei dati e offre diversi server proxy per soddisfare le tue esigenze. Con questo strumento puoi racimolare istantaneamente fino a 200 URL.

3. Scraper

È un'estensione di Chrome con proprietà di estrazione dei dati illimitate. Con Scraper puoi facilmente estrarre informazioni da un sito web dinamico, effettuare ricerche online ed esportare i dati su fogli di lavoro Google. Questo programma è adatto per freelance, sviluppatori di app, programmatori e non-programmatori. Scraper è un software gratuito che funziona nel tuo browser web e genera piccoli XPath. Definisce i tuoi contenuti web in un modo migliore e aiuta a scansionare le tue pagine web. Non è necessario affrontare la configurazione disordinata e le proprietà e le funzionalità di questo strumento sono simili a quelle di ParseHub.

4. Scrapinghub

Scrapinghub è uno dei migliori strumenti di scraping in rete e aiuta a recuperare dati preziosi usando un rotatore proxy specifico per eseguire i suoi compiti. Scrapinghub è meglio conosciuto per la sua interfaccia user-friendly e utilizza i robot per eseguire la scansione di pagine Web diverse. Fornisce protezione antispam completa ai propri utenti ed estrae i dati dell'intero sito Web con pochi clic.

5. VisualScraper

Proprio come ParseHub e Scrapinghub, VisualScraper è un raschietto web potente, affidabile e autentico. Con questo strumento, puoi estrarre dati da oltre 2000 URL alla volta. Il software aiuta a racimolare le informazioni da diversi blog e siti e recupera i risultati in tempo reale. È inoltre possibile utilizzare VisualScraper per estrarre informazioni da documenti PDF, file JPG e PNG e documenti HTML. Dopo aver raschiato i dati, è possibile esportarli in formati come SQL, JSON, CSV e XML. VisualScraper è compatibile con diversi browser Web e sistemi operativi ed è principalmente disponibile per gli utenti Windows e Linux.
