Semalt fornisce i risultati dei test di strumenti di raschiatura del web

by
Feb 09, 2018

Ogni utente affronta due opzioni quando desidera utilizzare gli strumenti di raschiatura del nastro. Utilizzano un raschietto per il web o un raschietto personalizzato. Mentre un raschietto personalizzato è un'opzione migliore, molte persone ne rifuggono a causa del suo alto costo. Lo strumento deve essere sviluppato per adattarsi al tuo business e alle tue preferenze, quindi richiede molto lavoro.

D'altra parte, i web scrapers disponibili sul mercato sono troppo generici poiché sono progettati per attività generali di scraping del web. Di solito sono migliori in alcuni progetti di scraping web e fanno lavori scadenti in altri. Per aiutarti a fare la scelta giusta, alcuni web scrapers sono stati sottoposti a test approfonditi di scraping web e i risultati sono stati visualizzati di seguito.

Criteri di test

I web scrapers sono stati testati nelle seguenti attività comuni di estrazione dei dati. Sono stati testati sulla loro capacità di raschiare report tabulari, elenchi di testo e moduli di accesso. Inoltre, i web scrapers sono stati testati anche sulla loro capacità di estrarre dati da pagine web dinamiche costruite su AJAX. Questo di solito è uno dei compiti più difficili per molti web scrapers. La loro capacità di gestire Captcha è stata messa alla prova. Infine, sono stati testati sulla loro capacità di gestire il layout dei blocchi.

Risultati del test

Gli strumenti di scraping Web testati sono Content Grabber, Visual Web Ripper, Helium Scraper, Screen Scraper, OutWit Hub, Mozenda, WebSundew Extractor, Web Content Extractor e Easy Web Extractor. (3

I risultati hanno dimostrato che Content Grabber è il migliore dal momento che ha funzionato in modo eccellente in tutte le aree testate, ottenendo il punteggio medio più alto, inoltre è stato rilevato che tutti gli strumenti di scraping web sono stati in grado di anche raschiare dati da pagine web create con AJAX, quindi se questi sono i due motivi per cui hai bisogno di un raschietto per il web, puoi sceglierne uno qualsiasi: tutti hanno funzionato molto bene in entrambe le aree.

Il prossimo a Content Grabber in performance è Visual Web Ripper, che ha ottenuto buoni risultati in tutte le aree ma non così come Content Grabber, quindi ha ottenuto una valutazione media di 4.5 Il prossimo strumento Web è Helium Scraper. Le sue prestazioni sono quasi altrettanto buone di quelle di Visual Web Ripper, l'unico problema con Helium Scraper è la sua scarso rendimento in ha layout del blocco ndling.

In base ai risultati del test, gli strumenti di scraping Web sono stati eseguiti in questo ordine: Content Grabber, Visual Web Ripper, Helium Scraper, Screen Scraper, OutWit Hub, Mozenda, WebSundew Extractor, Web Content Extractor e Easy Web Extractor che ha messo la peggiore performance.

Conclusione

Considerando i risultati dei test analizzati sopra, Content Grabber ha ottenuto un punteggio di 5 in tutte le categorie di test. Quindi, è ovviamente il migliore. Potrebbe essere necessario provarlo anche tu. Sfortunatamente, due web scrapers sono stati estratti dal test per diversi motivi. Gli sviluppatori di Web Data Extractor e WebHarvy hanno tirato fuori i loro prodotti dal test.

Nonostante non abbia preso parte al test, sono state apprese alcune cose su entrambi. WebHarvy è progettato per raschiare dati da elenchi impaginati ben formattati mentre Web Data Extractor è esclusivamente per la raccolta di e-mail, URL, ecc.
