  • Publication number: 20160314213
    Abstract: The present invention refers to a method for characterizing a group of users, related among them by their mobile communication data, according to web navigation data. The method comprises: building a social graph from the mobile communication data of a user and his contacts; extracting web navigation data of each user of the social graph; associating to each edge linking two users of the social graph, web navigation data extracted for both two users; obtaining a measure of harmony based on comparing web navigation data of both two users; and providing a set of metrics for the group of users based on the measures of harmony, characterizing the group of users.

  • Publication number: 20160307223
    Abstract: The invention relates to a method for determining a user profile in relation to certain web content, according to the user's browsing data. The method comprising the following steps: classifying the browsing data according to content categories; extracting a first set of variables from the user's web browsing data for each category; assigning the user a ranking position for each of the categories, and comparing the first set of variables with the same variables of other users; calculating at least one correction factor for the user's ranking position in each category according to one or more time variables extracted from the web browsing data; recalculating the user's ranking position for each category, taking into account the correction factor calculated for each category; and determining the user profile on the basis of the user's ranking position calculated for each category.

  • Patent number: 8812324
    Abstract: The invention relates to a method for speech signal analysis, modification and synthesis comprising a phase for the location of analysis windows by means of an iterative process for the determination of the phase of the first sinusoidal component and comparison between the phase value of said component and a predetermined value, a phase for the selection of analysis frames corresponding to an allophone and readjustment of the duration and the fundamental frequency according to certain thresholds and a phase for the generation of synthetic speech from synthesis frames taking the information of the closest analysis frame as spectral information of the synthesis frame and taking as many synthesis frames as periods that the synthetic signal has. The method allows a coherent location of the analysis windows within the periods of the signal and the exact generation of the synthesis instants in a manner synchronous with the fundamental period.
