Semalt Web Kazıma İçin En İyi Programlama Dillerini Öneriyor

by
Feb 08, 2018

Web kazıma nedir? Bu, veri madenciliği veya yararlı bilgi toplayan bir süreçtir. Çok sayıda aktif gelişme içeren kapsamlı bir alandır ve tüm web kazıma görevleri ortak bir hedefi paylaşır ve yapay zeka, anlambilimsel anlayış ve metin işleme alanlarında atılımlar gerektirir. Veri genellikle internetten bir web tarayıcısı veya Köprü Metni Aktarım Protokolü kullanılarak kazınır, ancak kazınmış olduğumuz import.io, Octoparse, Kimono Labs ve Mozenda gibi güçlü bir araçla da yapılabilir.

Web'den Kazıma İçin Farklı Programlama Dilleri:

Verileri internetten kazıyıp çıkarmak için yukarıda bahsedilen araçları kullanabilirsiniz veya web'inizi kazıma görevlerini manuel olarak gerçekleştirmek için bir programlama dili öğrenebilirsiniz.

1. Node.js:

Web kazıma ve veri sürünme için en iyi programlama dillerinden biridir. Node.js, öncelikle farklı web sayfalarını indekslemek için kullanılır ve aynı anda hem dağıtılmış tarama hem de veri kazımayı destekler. Bununla birlikte, node.js yalnızca temel düzeyde web kazıma projeleri için uygundur ve büyük ölçekli görevler için önerilmez.

C ve C ++:

Hem C hem de C ++ mükemmel bir kullanıcı deneyimi sağlar ve web kazıma için seçkin programlama dilleri. Temel veri kazıyıcıyı oluşturmak için bu dilleri kullanabilirsiniz, ancak web tarayıcıları oluşturmak için uygun değildir.

PHP:

PHP'nin web kazıma için en iyi programlama dillerinden biridir ve güçlü web kazıyıcılar ve uzantıları geliştirmek için yayınlandığını söylemek güvenlidir.

Python:

PHP gibi, Python web kazıma için popüler ve en iyi programlama dilidir. Bir Python uzmanı olarak, çoklu veri sürünerek veya web kazıma görevlerini rahatlıkla halledebilir ve gelişmiş kodları öğrenmeniz gerekmez. İstekler, Scrappy ve BeautifulSoup, en ünlü ve en çok kullanılan üç Python çerçevesidir. İstekler Scrapy ve BeautifulSoup'dan daha az bilinir, ancak çalışmalarınızı kolaylaştırmak için bir çok özelliği vardır. Scrapy, import.io'ya iyi bir alternatiftir ve temel olarak dinamik web sayfalarından verileri silmek için kullanılır. BeautifulSoup, etkin ve yüksek hızlı kazıma görevleri için tasarlanmış bir başka güçlü kitaplıktır.

Bu üç çerçeve veya kütüphane, farklı web kazıma görevlerini yerine getirmeye yardımcı olur ve hem programcılar hem de programcılar için uygun değildir.

Web Kazıyıcı İçin En İyi Programlama Dili Nedir?

Python genel amaçlı programlama için yorumlanmış üst düzey bir programlama dilidir ve internette hızlı bir hızda veri toplamanıza izin verir. Web kazıma için bugüne kadarki en iyi programlama dilidir ve çalışmalarınızı kolaylaştırmak için dinamik bir sistem ve otomatik bellek yönetimi özelliklerine sahiptir. Python'un en belirgin özelliklerinden biri onlarca çerçeveye ve kütüphaneye sahip olması ve öğrenmesi kolay olmasıdır. PHP, web geliştirme ve web kazıma görevleri için tasarlanmış sunucu tarafı betik dili olup genel amaçlı bir programlama dili olarak kullanılır. Python'un PHP ve diğer programlama dillerinden çok daha iyi olduğu ve hem basit hem de dinamik web sayfalarını hedeflemek için kullanılabileceği anlamına gelir. Ayrıca, Python'u kullanarak kendi çerçevenizi veya web kazıyıcınızı oluşturabilir ve kazınmış verilerinizin kalitesi hakkında endişelenmeniz gerekmez.
