A technique for mining pharmacophore patterns including computer-implemented methods for generating a database of pharmacophores and computer-implemented methods for classifying a query molecule with the database of pharmacophores. Generation of the pharmacophore database includes methods of defining a Joint Pharmacophore Space (JPS) using the three-dimensional geometry of pharmacophoric features of all active molecules against multiple targets.

Defining and mining a joint pharmacophoric space through geometric features

A method, a system and a computer program product for maximizing content spread in a social network are provided. Samples of edges are generated from an initial candidate set of edges. Each edge of the samples of edges has a probability value for content flow. Further, a subset of edges is determined from the samples of edges based on gain corresponding to each edge. Also, each node of the subset of edges is having at least one of less than 'K' or equal to 'K' incoming edges. Further, the probability of each edge, of the subset of edges, may be incremented. Furthermore, a final set of edges may be determined by ensuring &#x2018;K&#x2019; incoming edges. The &#x2018;K&#x2019; incoming edges may be ensured by removing one or more incoming edges when a number of the incoming edges for a node of the final set is greater than &#x2018;K&#x2019; incoming edge.

Method and system for maximizing content spread in social network

A method for analyzing, querying, and mining graph databases using subgraph and similarity querying. An index structure, known as a closure tree, is defined for topological summarization of a set of graphs. In addition, a significance model is created in which the graphs are transformed into histograms of primitive components. Finally, connected substructures or clusters, comprising paths or trees, are detected in networks found in the graph databases using a random walk technique and a repeated random walk technique.
