Abstract: In one embodiment, it is proposed a method for storing input data on a set of DNA strands, said input data being represented in a numeral system. This method is remarkable in that it comprises: formatting said input data into a set of blocks of data, each block of data having a size inferior to a size of one DNA strand; applying a first encoding with an erasure code on said set of blocks of data, defining a first set of modified blocks of data, each modified block of data having a size inferior to a size of one DNA strand; applying a second encoding using an error correcting code on each modified block of data of said first set, defining a second set of modified blocks of data, each modified block having a size inferior to a size of one DNA strand; encoding each modified block of data of said second set into a nucleotides block sequence; generating a set of DNA strands, each DNA strand comprising a nucleotides block sequence obtained through said encoding.

Abstract: This relates to message propagation in an opportunistic communication network. Nodes of the network each have a ranking which is compared when the nodes connect, and message is transferred from one node to the other in dependence on the relative values of their respective rankings. The ranking is dependent on a plurality of parameters. One parameter is a social parameter determined by the social contacts of a user associate with a node, for example determined from the contact directory of that person either locally or from a central database such that located on a Face book servicer. Another parameter is the number of physical connections established by a node. The ranking values of connecting nodes is updated when they connect. By combining both parameters, a more efficient forwarding path for messages is obtained.

Abstract: The present invention provides a method for computing traffic between a pair of Points of Presence in an IP network by summing link utilization values measured for each link connecting a pair of Points of Presence and dividing the sum by the number of link utilization values included in the sum. The resulting average link utilization is the average link utilization of any link in the aggregate and may be multiplied by the number of active links connecting a pair of Points of Presence to reflect the total amount of traffic between the two Points of Presence. Future link utilization may be forecast by modeling the observed traffic between a pair of Points of Presence using wavelet multiresolution analysis to create an approximation curve that captures the long-term trend of link utilization and at least one detail curve that captures the short term deviation of link utilization around the long-term trend. A time series model of the approximation curve may then be constructed and used for forecasting.

Abstract: A method and apparatus for retrieving information from a massive amount of user-written businesses reviews are described. From the bag of words of a given review set, a graph based on mutual information between the words is built. Spectral analysis on this graph enables creation of a Euclidean space specific to those reviews where the distance corresponds to semantic proximity. Applying a cover-tree based divisive hierarchical clustering in this space yields therefore a semantic tag tree. Such a taxonomy is specific of the review set used, which could be all the reviews about a product or written by a user, and can be used for profiling. These taxonomies are used to build profiles. Also described is a tool to summarize and browse the review set based on the obtained trees.
