Abstract

Diversos métodos están utilizando extracción de datos basada en SQL para extraer información relevante de las imágenes. Estos son métodos basados en reglas para generar SQL-Consulta de NL, si se van a manejar oraciones en inglés nuevas entonces se requiere intervención manual. Además se vuelve difícil para un usuario no técnico. Se proporciona sistema y método para extraer información relevante de las imágenes utilizando una interfaz conversacional y consulta de base de datos. El sistema elimina los efectos ruidosos, identifica el tipo de documentos y detecta varias entidades para diagramas. Además se diseña un esquema que permite una abstracción fácil de entender de las entidades detectadas por los modelos de visión profunda y las relaciones entre estos. Información y campos relevantes entonces pueden ser extraídos del documento escribiendo consultas SQL encima de las tablas de relación. Se añade una interfaz basada en lenguaje natural de manera que un usuario no técnico, que especifica las consultas en lenguaje natural, puede extraer la información sin esfuerzo.
