An image based information retrieval system for engineering projects
نویسندگان
چکیده
Today there is a great amount of information in the form of engineering projects. The difficulty in retrieving visual information contained in engineering projects in various contexts in which engineering designs are used as inputs in decision making is an area of major concern. Current methods of retrieval do not satisfy the demand for the rapid and precise location of information contained in large sets of drawings. This is because the projects are retrieved through the utilization of codes and keywords that only partially represent their content. This paper addresses this problem by proposing an image based information retrieval system for engineering projects. The article presents a conceptual model, a classification scheme and a prototype of an information retrieval system (IRS) for engineering projects that uses a key-image to retrieve a document. The prototype was tested and validated in a case study conducted at the Military Fire Department of the State of Minas Gerais (MFDMG), Brazil. The system proposed would positively impact services and decision making in areas such as infrastructure (sanitation, energy and roads), safety, healthcare and education. 1 Information retrieval, image retrieval, engineering projects, information retrieval based on image visual content.
