DotnetSpider
DotnetSpider es un framework de rastreo web para .NET y una herramienta de extracción de datos en C# diseñada para el descubrimiento automatizado de páginas web y la recuperación de datos estructurados de Internet a gran escala. Funciona como una librería de web scraping de alto nivel para recopilar información de varios sitios web.
El framework proporciona capacidades para el rastreo web automatizado y el scraping de datos a gran escala. Permite la extracción de contenido web para facilitar la creación de bases de datos locales o el análisis de información en línea mediante la automatización web programática dentro del ecosistema .NET.
El sistema utiliza un modelo de procesamiento de datos basado en tuberías con manejo de solicitudes asíncronas y ejecución de trabajadores concurrentes. Cuenta con un programador basado en colas de tareas, proveedores de almacenamiento modulares y una implementación orientada a interfaces para lógica de scraping personalizada.
