Method (1, 101, 201, 301) for accessing information related to a reference entity (o R) by means of a display device, including: a) providing an ontology describing a first plurality of entities, the first plurality of entities being a plurality of classes of the ontology or being arranged into a plurality of classes, each of said plurality of classes having respective properties; b) receiving information for identifying the reference entity (o R) out of the first plurality of entities; characterised by comprising: c) calculating a first network of entities (o 2, o 5, o 9) out of the first plurality of entities, said entities of the first network having first relationships (r 5, r i, r j) with the reference entity (o R) and having relationships with other entities of the ontology, according to said properties; d) identifying a plurality of display area portions (61, 62, 63, 64) available on an area of the display device, according to the plurality of classes of the ontology; e) assigning the entities of the first network to at least one of the plurality of display area portions (61, 62, 63, 64); e1) displaying over each of the plurality of display area portions (61, 62, 63, 64) identifying text and/or image data which meaning is associated to the entities which are assigned within the respective portion; f) selecting, by a user, a display area portion out of the plurality of display area portions (61, 62, 63, 64); g) displaying, over the selected display area portion, a plurality of images and/or text data (71, 72, 73) for indicating at least part of the entities of the first network assigned to the selected display area portion; h) selecting, by a user, a first entity (o 5) out of the entities of the first network of entities displayed in the selected display area portion; i) displaying, over the selected display area portion and contemporaneously with the displaying of the plurality of images and/or text data (71, 72, 73) for indicating at least part of the entities of the first network, at least one image and/or text data describing one or more of the first relationships (r 5, r i r j) between the reference entity (O R) and the selected first entity (o 5), and one or more of the relationships between the selected first entity (o 5) and the other entities of the ontology. a) providing an ontology describing a first plurality of entities, the first plurality of entities being a plurality of classes of the ontology or being arranged into a plurality of classes, each of said plurality of classes having respective properties; b) receiving information for identifying the reference entity (o R) out of the first plurality of entities; c) calculating a first network of entities (o 2, o 5, o 9) out of the first plurality of entities, said entities of the first network having first relationships (r 5, r i, r j) with the reference entity (o R) and having relationships with other entities of the ontology, according to said properties; d) identifying a plurality of display area portions (61, 62, 63, 64) available on an area of the display device, according to the plurality of classes of the ontology; e) assigning the entities of the first network to at least one of the plurality of display area portions (61, 62, 63, 64); e1) displaying over each of the plurality of display area portions (61, 62, 63, 64) identifying text and/or image data which meaning is associated to the entities which are assigned within the respective portion; f) selecting, by a user, a display area portion out of the plurality of display area portions (61, 62, 63, 64); g) displaying, over the selected display area portion, a plurality of images and/or text data (71, 72, 73) for indicating at least part of the entities of the first network assigned to the selected display area portion; h) selecting, by a user, a first entity (o 5) out of the entities of the first network of entities displayed in the selected display area portion; i) displaying, over the selected display area portion and contemporaneously with the displaying of the plurality of images and/or text data (71, 72, 73) for indicating at least part of the entities of the first network, at least one image and/or text data describing one or more of the first relationships (r 5, r i r j) between the reference entity (O R) and the selected first entity (o 5), and one or more of the relationships between the selected first entity (o 5) and the other entities of the ontology.
