Within the development of software systems, the development of web applications may be one of the most
widespread at present due to the great number of advantages they provide such as: multiplatform, speed of
access or the not requiring extremely powerful hardware among others. The fact that so many web applications
are being developed, makes grotesque the volume of information that it is generated daily. In the management
of all this information, it appears the entity reconciliation problem, which is to identify objects referring to
the same real-world entity. This paper proposes to give a solution to this problem through a web perspective.
To this end, the NDT methodology has been taken as a reference and has been extended adding new activities,
artefacts and documents to cover this problem.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2016-76956-C3-2-RMinisterio de Economía y Competitividad TIN2015-71938-RED
