Abstract: The present invention relates to techniques to analyze and organize bodies of knowledge into information networks. More particularly, it relates to a method for measuring distance among and organizing similar concepts representing human knowledge, whose information is contained, as example, in databases of documents. In particular, said method comprises: a) obtaining a plurality of type of entities and their relative properties, wherein at least two of said entities share at least one property; b) creating a multi-partite graph; c) making a projection for each type of entity onto each of their type of properties to obtain a proximity matrix, or a weighted graph, for each pair type of entity-type of property; d) obtaining a family of proximity matrices for each type of entity; e) querying the computed results in a format so that for each type of entity, portions of proximity matrices, or weighted graphs, of said family, are interactively accessed, represented or displayed.
