The present disclosure is directed to systems and methods that include a beacon that includes an antenna; data storage configured to store a code that is calculated according to an algorithm and based on a first variable, the first variable being defined according to a first interval of time; and a processor configured to cause the code to be emitted by the beacon.

Systems and methods are provided for retrieving data relevant to a subject of interest. Occurrences of each of a plurality of n-grams within the data record are identified. A multinomial distribution is defined from the respective numbers of occurrence of a subset of the plurality of n-grams. The multinomial distribution is stored in a semantic model as a point on an information manifold. The semantic model is configured to represent an indexed family of probability distributions as points on the information manifold. It is determined if the data record is relevant to the subject of interest according to the position of the point on the information manifold, and the data record is retrieved if the data record is relevant to the subject of interest.
