Semalt Uzmanı: Yüksek verimli bir Web İçerik Çıkarıcı

by
Feb 13, 2018

Bir web içeriği çıkarıcı nasıl çalıştığını anlamak için, bir web içeriğinin ne olduğunu bulmak gerekir. Basitçe, web içeriği bir web sayfasında gördüğünüz herhangi bir şeydir. Bunlar elbette resimler, ses dosyaları, videolar ve metinlerdir. Bazen, düzgün şekilde düzenlenmiş ve çıkartılması kolay içeriğe rastlarsınız ve bazen içerik elle kopyalayıp yapıştırmanın çok zor olduğu bir web sayfasıyla karşı karşıya kalabilirsiniz. Çoğu zaman sorun, içeriğin kendisi değil, kazımak zorunda olduğunuz web sayfalarının hacmidir.

Örneğin, herhangi birinin yüzlerce sayfadan içeriği manuel olarak kopyalayabildiğini düşünüyor musunuz? Ya günlük olarak yapılması gerekiyorsa? Burada bir web içeriği çıkarıcı gelir. Bir web içeriği çıkarıcı, yapılandırılmış, yarı yapılandırılmış veya yapılandırılmamış web sayfalarından verileri sıyırmak için kullanılabilen bir yazılım, araç, program veya uygulamadır. Bir web içeriği çıkarıcısının ne olduğunu tanımladıktan sonra, basitçe web veri çıkarımının ne olduğunu tanımlamak gerekir.


Kısacası, web veri çekme, web sayfalarını taramak ve onlardan belirlenmiş verileri ayıklamak için bir araç, yazılım veya komut dosyası kullanmak için kullanılan bir işlemdir. Bu araç, kazınmış verileri yapılandırılmış bir biçimde sunmak için de kullanılabilir. Sorun şu ki, çok az insan bir web kazıma programı geliştirebilir. WebSundew web veri çıkarıcıyı doğuran şey buydu.

Çıkarıcı, çoklu web sayfalarından çok kısa bir süre içinde çeşitli veri öğelerini çıkarmak için geliştirildi. WebSundew web içeriği çıkarıcı her türlü web sayfasından verileri sıyırabilir. Bu nedenle, çeşitli sektörlerden şirketler, kötü yapılandırılmış verileri çok sayıda web sayfasından sıyırmak için kullanıyorlar. Elbette, esnekliği nedeniyle onlara mükemmel hizmet ediyor.

Araç aşağıdaki alanlarda kullanılır:

  • İnsan kaynakları endüstrisi
  • Çevrimiçi medya
  • Işe alma ajansı
  • Taşımacılık endüstrisi
  • Eğitim yönetimi
  • Telekomünikasyon
  • Tüketim malları
  • Hükümet yönetimi
  • Bilgi teknolojisi ve hizmetleri
  • Emlak
  • Perakende
  • Muhasebe
  • Sigorta
  • İlaç endüstrisi
  • Bilgisayar ve ağ güvenliği
  • Lojistik ve tedarik

Aracın çok verimli, doğru olması ve programlama bilgisi gerektirmemesi nedeniyle bu liste daha uzun sürecektir. Web veri çıkarma her işin vazgeçilmez bir parçası haline geldiğinden, web veri çıkarma araçlarının önemi fazla tahmin edilemez.

Bu araç çok verimli olmasına rağmen, geliştiricileri daha iyi hale getirmeye çalışan kullanıcıların geri bildirimine açıktır. Web ekstraksiyonu için başka araçlar olmasına rağmen, WebSundew web içeriği çıkarıcı en doğru ve hızlı olanlardan biridir. Birkaç dakika içerisinde yüzü aşkın web sayfasından veri ayıklayabilir. Kısacası, ürünün kullanımı çok kolay ve aynı zamanda müşteri odaklı.
