Semalt proporciona los resultados de prueba de herramientas de raspado web

Feb 05, 2018

Cada usuario enfrenta dos opciones cuando quiere usar herramientas de raspado web. O bien usan un raspador web o un raspador personalizado. Si bien un raspador personalizado es una mejor opción, mucha gente se aleja de él debido a su alto costo. La herramienta debe ser desarrollada para adaptarse a su negocio y preferencias, por lo que requiere mucho trabajo.

Por otro lado, los raspadores web listos para usar son demasiado genéricos ya que están diseñados para tareas generales de raspado web. Por lo general, son mejores en algunos proyectos de web scraping y hacen trabajos de mala calidad en otros. Para ayudarlo a tomar la decisión correcta, algunos raspadores web fueron sometidos a minuciosas pruebas de raspado web y los resultados se muestran a continuación.

Criterios de prueba

Los raspadores web se probaron en las siguientes tareas comunes de extracción de datos. Fueron probados en su capacidad para raspar informes tabulares, listas de texto y formularios de inicio de sesión. Además, los raspadores web también fueron probados en su capacidad para extraer datos de páginas web dinámicas construidas en AJAX. Esta suele ser una de las tareas más difíciles para muchos raspadores web. Su capacidad para manejar Captcha también se puso a prueba. Por último, fueron probados en su capacidad para manejar el diseño del bloque.

Resultados de la prueba

Las herramientas de web scraping que se probaron son Content Grabber, Visual Web Ripper, Helium Scraper, Screen Scraper, OutWit Hub, Mozenda, WebSundew Extractor, Web Content Extractor y Easy Web Extractor.

Los resultados mostraron que Content Grabber es el mejor ya que tuvo un excelente desempeño en todas las áreas evaluadas, por lo que obtuvo la calificación promedio más alta. También se observó que todas las herramientas de raspado web podían eliminar los formularios de inicio de sesión y También raspe los datos de las páginas web creadas con AJAX. Si estas son las dos razones por las que necesita un raspador web, puede elegir cualquiera. Todas funcionaron muy bien en ambas áreas.

El siguiente al Content Grabber en rendimiento es Visual Web Ripper. Se desempeñó bien en todas las áreas, pero no tan bien como Content Grabber, por lo que obtuvo una calificación promedio de 4.5. La siguiente herramienta web es Helium Scraper. Su rendimiento es casi tan bueno como el de Visual Web Ripper. El único problema con Helium Scraper es su bajo rendimiento en ha ndling diseño de bloque.

Según los resultados de la prueba, las herramientas de raspado web se realizaron en este orden: Content Grabber, Visual Web Ripper, Helium Scraper, Screen Scraper, OutWit Hub, Mozenda, WebSundew Extractor, Web Content Extractor y Easy Web Extractor que presentó el peor rendimiento.

Conclusión

Teniendo en cuenta los resultados de las pruebas analizadas anteriormente, Content Grabber obtuvo una calificación de 5 en todas las categorías de prueba. Entonces, obviamente es lo mejor. Es posible que tengas que probarlo también. Desafortunadamente, dos raspadores web se retiraron de la prueba por diferentes razones. Los desarrolladores de Web Data Extractor y WebHarvy sacaron sus productos de la prueba.

A pesar de no participar en la prueba, se aprendieron algunas cosas sobre ambos. WebHarvy está diseñado para extraer datos de listas paginadas bien formateadas mientras Web Data Extractor es únicamente para recopilar correos electrónicos, URL, etc.
