Central to this paradigm is the use of globally unique singular identifiers--called IUIs (for Unique Instance Identifiers)---that stand proxy for the entities in reality to which they refer. For an identifier to be an IUI, it must refer to one and only one particular, and this tight connection between the particular and its IUI must be asserted by an author in an RT system (RTS). One purpose of the RTS is to give agents who wish to make statements about entities in reality a means to retrieve IUIs for particulars to which identifiers have already been assigned, and to create IUIs in other cases. Another purpose is to provide an efficient way to store data about particulars in terms of their relations to other particulars and to the universals which they instantiate. The applicability of RT has, since its inception, been assessed in areas such as electronic healthcare record keeping, digital rights management, automated decision support, corporate memories in enterprises, intelligence, and outcome assessment. In a recently started project, it is used to bridge the gap between dimensional versus categorical approaches to psychiatric diagnoses. Of course, RT presents some challenges of its own. One specific problem is how to represent phenomena commonly expressed by statements such as: "no history of diabetes", "hypertension ruled out", "absence of metastases in the lung", and "abortion was prevented". Such statements seem at first sight to present a problem for RT, since there are no entities on the side of the patient to which unique identifiers can be assigned. Another challenge is keeping track of the different kinds of changes, reflecting for example: (1) changes in the underlying reality, either in a specific patient's condition or the world in general; (2) changes in our understanding; (3) reassessments of what is considered to be relevant for inclusion in a referent tracking database, or (4) encoding mistakes introduced during data entry. The presentation aims to give an overview of the state of the art in RT. One specific goal is to find amongst the audience researchers that are either interested to contribute to the research, or to apply referent tracking in their research such that we can set up collaborative grant proposals.
