Nowadays there is a growing research activity centred in automated processing of texts on electronic form. One of the most common problems in this field is co-reference resolution, i.e. the way of knowing when, in one or more texts, different descriptions refer to the same entity. A full co-reference resolution is difficult to achieve and too computationally demanding; moreover, in many applications it is enough to group the majority of co-referential expressions (expressions with the same referent) by means of a partial analysis. Our research is focused in co-reference resolution restricted to proper names, and we part from the definition of a new relation called "replicancia". Though replicancia relation does not coincide extensionally nor intensionally with identity, attending to the tests we have carried out, the error produced when we take the replicantes as co-referents is admissible in those applications which need systems where a very high speed of processing takes priority.
