Semalt proporciona problemas útiles en los 5 mejores raspadores web

Dec 01, 2017

A menudo, la información que necesitamos queda atrapada en un sitio, y no puede raspar o arrastrarlo apropiadamente. Si bien algunos sitios se esfuerzan por presentar los datos en formatos limpios y estructurados, los demás no pueden proporcionar ningún servicio de rastreo web o de depuración de datos. Es por eso que tendremos que acceder a los mejores rastreadores web, mineros y raspadores. Aquí hemos discutido las cinco herramientas principales a este respecto.

1. Webhose.io:

Webhose.io nos permite obtener los datos en tiempo real de los recursos y sitios en línea. La mejor parte es que este programa analiza y rastrea los sitios de manera conveniente y presenta los datos en un formato limpio y bien organizado. También nos permite recopilar datos en función de sus palabras clave, frases, idiomas y naturaleza. Los resultados finales se pueden obtener en forma de archivos XML, RSS y JSON. Si bien este programa es gratuito, puede acceder a su versión premium si desea usar Webhose.io con fines comerciales. El plan pago le permitirá enviar múltiples solicitudes HTTP al servidor principal, lo que le facilitará raspar y rastrear los sitios.

2. Scrapy:

Scrapy es un marco potente y sorprendente para rastrear y rastrear en Internet. Su mejor parte es que este programa cuenta con el respaldo de una comunidad de expertos, con quienes puede ponerse en contacto para obtener sugerencias útiles y tutoriales en cualquier momento y en cualquier lugar. Ayuda a raspar y analizar sus datos y los guarda en diferentes formatos, como CSV y JSON.

3. Outwit Hub:

Si no te sientes cómodo con los códigos, Outwit Hub te proporcionará la interfaz visual útil, lo que te facilitará rastrear y extraer los datos. Su versión alojada está disponible en el sitio oficial, y la versión gratuita se puede descargar desde cualquier tienda en línea. Outwit Hub es una extensión de Firefox que no requiere que tengas habilidades de programación.

4. Octoparse:

Al igual que Outwit Hub, Octoparse es un poderoso web scraper, crawler y data miner. Maneja sitios estáticos y dinámicos usando Javascript, cookies, redirects y AJAX. Este programa web ayudará a extraer cualquier sitio o blog y extraerá los tipos de datos básicos y avanzados. Toda la información valiosa que necesita se puede encontrar en el área de almacenamiento en la nube de Octoparse. Le permite extraer sitios web a granel en una hora y obtendrá la mejor calidad con Octoparse API. Déjame decirte que este software gratuito solo es compatible con Windows y no está disponible para ningún otro sistema operativo.

5. Web Scraper para Chrome:

Si tiene Google Chrome como su navegador web principal, debe optar por Web Scraper. Es un excelente programa de rastreo y minería que le permite crear mapas de sitio para sus blogs personales y sitios web comerciales. Solo tiene que descargar, instalar y agregar este raspador a su navegador Chrome y ver cómo extraerá datos de sus sitios web. También puede importar los mapas de sitio o usar sus plantillas para mejorar el aspecto general y el rendimiento de su sitio web. Guardará sus datos extraídos en los archivos CSV o en su propia carpeta de Archivo.
