The present disclosure generally relates to computing methods and applications. A service platform includes standard functionalities that can be used in different applications, such as composite applications. The service platform includes a database that stores application specific information, which is mapped to the standard functionalities. To use these functionalities, different applications initialize relevant parts of the database and use predefined standards to access these functionalities.

A method determines a number of unique values in a sample of a list of values and estimates a number of the unique values for an unsampled portion of the list of values. The method estimates a number of the unique values in the list by adding the number of unique values in the sample to the number of the unique values in the unsampled portion.

A process is provided for mapping the relationship of the content of a collection of documents (14). The process includes providing a collection (12) of documents (14) where each document (14) includes text. Relevance measures are determined that represent a relevance between each pair of documents (14) based upon the text of the documents (14). A graph (22) is then generated that has nodes (30) and edges (32) with each edge (32) connecting two nodes (30). The graph (22) has a node (30) associated with each document (14) and has an edge (32) connecting nodes (30) for which the relevance measure between associated documents (14) is greater than a specified threshold. In this manner, the graph (22) maps the relationship of the content of the collection (12) of documents (14).

A system (10) for recursive document retrieval is provided. An original repository (12) comprises a plurality of documents (14), and a query (16) comprises information by which the original repository (12) can be analyzed to identify relevant documents (14). A retrieval engine (18) is coupled to the original repository (12) and receives the query (16). The retrieval engine (18) is operable to execute an automatic recursive retrieval process with respect to the original repository (12) using the query (16) where the automatic recursive retrieval process comprises a plurality of iterations. The retrieval engine (18) is also operable to provide as system output a retrieved repository (28) comprising a plurality of documents (30) from the original repository (12) identified as sufficiently relevant to the query (16) according to the automatic recursive retrieval process for detection as relevant documents.

According to one embodiment of the present invention, a system (10) for arrangement of documents (13) is provided. The system includes a document repository (12) storing a plurality of documents (13). An arrangement engine (14) is coupled to the document repository (12). The arrangement engine (14) is operable to build a plurality of symmetric matrices based upon a plurality of identified arrangements of the plurality of documents (13) in the document repository (12). Each matrix is structured such that each row and each column is associated with a document (13). The arrangement engine (14) is also operable: to fill each cell of each symmetric matrix with a relevance value representing a relevance between a document (13) associated with the row of the cell and a document (13) associated with the column of the cell, to generate a fitness value for each matrix based upon a magnitude and a position of each relevance value by analyzing each symmetric matrix using a fitness function (16), to identify an optimal arrangement of the plurality of documents (13) based upon the fitness value of each matrix, and to provide the optimal arrangement of documents (18) as system output.

A process is provided for determining relevance using an electronic system. The process includes providing a first feature vector, providing a second feature vector, and providing an indexing parameter. A parametric family of sampling distributions are provided for the first feature vector using the indexing parameter. A parametric family of sampling distributions are also provided for the second feature vector using the indexing parameter. The process further includes providing a prior distribution of the indexing parameter. A distribution of the indexing parameter, given the second feature vector and an event that the first feature vector is not relevant to the second feature vector, is assigned the value of the prior distribution of the indexing parameter. A distribution of the indexing parameter, given the second feature vector and an event that the first feature vector is relevant to the second feature vector, is assigned the value of the posterior distribution of the indexing parameter given the second feature vector. A log likelihood ratio that the first feature vector is relevant to the second feature vector is then generated using the two assigned distributions of the indexing parameter. The log likelihood ratio is stored as representing relevance between the first feature vector and the second feature vector.
