Semalt suggerisce i migliori linguaggi di programmazione per il Web Scraping

Che cos'è il raschiamento del nastro? È un processo di estrazione dati o raccolta di informazioni utili dal web. È un vasto campo con molti sviluppi attivi e tutte le attività di scraping web condividono un obiettivo comune e richiedono innovazioni in intelligenza artificiale, comprensione semantica e elaborazione del testo. I dati vengono solitamente scaricati da Internet utilizzando un browser Web o tramite il protocollo di trasferimento ipertestuale, ma lo scraping può essere eseguito anche con un potente strumento come import.io, Octoparse, Kimono Labs e Mozenda.

Linguaggi di programmazione diversi per il Web Scraping:

È possibile utilizzare i suddetti strumenti per raschiare dati da Internet o apprendere un linguaggio di programmazione per eseguire manualmente le attività di raschiamento web.

1. Node.js:

È uno dei migliori linguaggi di programmazione per il web scraping e la scansione dei dati. Node.js viene principalmente utilizzato per l'indicizzazione di pagine Web diverse e supporta sia la scansione distribuita che lo scraping dei dati alla volta. Tuttavia, node.js è adatto solo per i progetti di raschiamento web di livello base e non è consigliato per attività su larga scala.

C e C ++:

Sia C che C ++ offrono un'ottima esperienza utente e sono linguaggi di programmazione eccezionali per il web scraping. Puoi utilizzare questi linguaggi per creare raschietti di dati di base, ma non sono adatti alla creazione di crawler web.

PHP:

È sicuro menzionare che PHP è uno dei migliori linguaggi di programmazione per il web scraping e viene rilasciato per sviluppare potenti web scrapers ed estensioni.

Python:

Proprio come PHP, Python è un linguaggio di programmazione popolare e migliore per il web scraping. In qualità di esperto Python, puoi gestire comodamente più attività di scansione dei dati o di scraping web e non devi imparare codici sofisticati. Requests, Scrappy e BeautifulSoup, sono tre framework Python più famosi e ampiamente usati. Le richieste sono meno conosciute di Scrapy e BeautifulSoup ma possiedono molte funzionalità per facilitare il tuo lavoro. Scrapy è una buona alternativa a import.io ed è principalmente utilizzato per raschiare dati da pagine web dinamiche. BeautifulSoup è un'altra potente libreria progettata per attività di scraping efficaci e ad alta velocità.

Questi tre framework o librerie aiutano a svolgere diversi compiti di scraping del web e sono adatti sia per programmatori che per non programmatori.

Qual è il miglior linguaggio di programmazione per il Web Scraping?

Python è un linguaggio di programmazione di alto livello interpretato per la programmazione generica e consente di acquisire dati da Internet a una velocità elevata. È di gran lunga il miglior linguaggio di programmazione per il web scraping e presenta un sistema di tipo dinamico e gestione automatica della memoria per facilitare il tuo lavoro. Una delle caratteristiche più distintive di Python è che ha dozzine di framework e librerie ed è facile da imparare. PHP è il linguaggio di scripting lato server progettato per attività di sviluppo Web e di scraping web, ma è utilizzato come linguaggio di programmazione generico. Significa che Python è di gran lunga migliore di PHP e di altri linguaggi di programmazione e può essere utilizzato per indirizzare sia pagine web semplici che dinamiche. Inoltre, puoi creare il tuo framework o raschietto web usando Python e non devi preoccuparti della qualità dei tuoi dati raschiati.
