Semalt Octoparse Review: raschiatura facile per tutti

Feb 09, 2018

La scienza dei dati è un campo interdisciplinare di metodi, sistemi e processi scientifici. Aiuta ad estrarre informazioni da diverse pagine Web e impiega tecniche e teorie tratte dalle vaste aree della statistica, dell'informatica, dell'informatica e della matematica. Octoparse è adatto per i dati scienziati e li aiuta a racimolare comodamente un gran numero di siti e blog.

Raccogliere dati utili con Octoparse:

Una delle caratteristiche più distintive di Octoparse è che raccoglie dati utili da Internet. Questo strumento naviga fondamentalmente attraverso diverse pagine Web, identifica i contenuti utili, li scansiona e li scarica sul disco rigido per usi offline. Octoparse è un raschietto web gratuito che ha più di 170.000 utenti attivi in tutto il mondo. Dal 2014, ha raschiato centinaia di migliaia di pagine web.

Adatto per imprese e grandi aziende:

A differenza di altri servizi di scraping web ordinari, Octoparse è compatibile con tutti i sistemi operativi e browser web. Questo strumento è adatto a imprese e aziende di grandi dimensioni. Garantisce la fornitura di dati accurati e utili e corregge tutti gli errori minori nei tuoi documenti web.

Una buona alternativa all'importazione.io:

Gli sviluppatori e i programmatori non possono raccogliere le informazioni manualmente. Di solito usano import.io e Kimono Lab per eseguire attività di scraping dei dati. Sfortunatamente, sia Kimono Labs che Import.io non garantiscono la fornitura di contenuti leggibili. A differenza di questi servizi, Octoparse promette risultati accurati e autentici. Questo strumento trasforma i dati non strutturati in informazioni strutturate e garantisce la fornitura di contenuto scalabile. Inoltre, Octopar non disturba la posizione delle parole chiave a coda corta e coda lunga. Invece, raschia i dati in base alle parole chiave e aiuta a migliorare le classifiche del tuo sito.

Nessuna competenza di programmazione richiesta:

La maggior parte degli strumenti di scraping dei dati richiede l'apprendimento di diversi linguaggi di programmazione come Python, C ++, Ruby e PHP. Octoparse ti consente di raccogliere e raschiare dati dal Web senza doverti codificare. Estrae automaticamente il contenuto da diverse pagine Web, lo organizza in base alle proprie esigenze e salva i risultati finali nel proprio database. È inoltre possibile trasformare i dati in un'API personalizzata e non è necessario assumere tonnellate di stagisti per copiare e incollare manualmente. Hai solo bisogno di evidenziare il contenuto web che vuoi estrarre e Octoparse farà il resto.

Estrarre informazioni dai social media:

Esistono diversi metodi per raschiare i dati. Alcuni siti Web forniscono API pubbliche per consentire agli utenti di accedere ai propri set di dati come Twitter, Facebook e LinkedIn. Potrebbe non essere possibile per te raccogliere informazioni da questi siti di social network. Octoparse estrae i dati da tutti questi siti ed è meglio conosciuto per la sua tecnologia di apprendimento automatico. Con questo strumento, puoi raccogliere informazioni da Facebook, Google+, LinkedIn e Twitter e scaricare i dati estratti sul tuo disco rigido in modo facile e conveniente. Di solito, la gente raschia questi siti usando Python e Ruby. Con Octoparse, non devi dipendere da questi linguaggi e non hai bisogno di capacità di codifica. Questo strumento eseguirà più attività di scraping dei dati e fornirà risultati scalabili e affidabili.
