Abstract: 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.

Abstract: Systems and methods are provided for identifying and displaying dependencies. One aspect of the invention comprises a system having a dependency parser that parses components of a system with dependencies and generates a plurality of component dependency pairs associated with the components, and a component dependency graph generator that generates a dependency directed graph from the plurality of dependency pairs. The system further includes a component levels and cycles analyzer that traverses the dependency directed graph to identify dependencies, strong components and component dependency levels associated with the dependency directed graph, and a graphical user interface that provides a tree view illustrating a dependency tree of the identified dependencies over the identified component dependency levels.
