Abstract: A computer implemented method of ranking items of data stored in a database comprising a plurality of records, wherein each record is associated with one or more items of data. The method includes generating a concordance of the items of data associated with the records in the database. Each record is assigned to a first group of records or to a second group of records. For each item of data a first indicator is determined representative of its occurrences in the records of the first group. For each item of data a second indicator is determined representative of its occurrences in the records of the second group. For each item of data a score is determined representative of a discriminative power of that item of data on the basis of the first and second indicator of that item of data.

Abstract: A computer implemented method of accessing a data set comprising a plurality of records, wherein each record is associated with one or more items of data. The method comprises using the computer to receive a data query on the data set. Each record is assigned to an in-group or to an out-group with respect to the query. Words appearing in records of the in-group are determined and a user interface representative of said words is generated. Words appearing in records of the out-group are determined and a user interface representative of said words is generated.

Abstract: A data analysis system (1) for displaying data facilitating visual analysis of communication transaction is disclosed. The system includes a transactions database (3) operable to store transaction records (5) defining communication transactions and a processing module (11) operable to determine a hierarchy having a tree structure wherein leaf nodes in the lowest level of the hierarchy correspond to sources and destinations associated with communication transactions represented by transaction records 5) stored in the transactions database (5).

Abstract: Apparatus and methods of generating a display representing a number of interactions occurring over a period of time is disclosed. Data defining a set of interactions is processed to determine an ordering for the interacting elements identified by the data based on calculated distance values for relative positions of pairs of interacting elements corresponding to interactions in the set. The determined ordering can then be used to generate display data where individual interactions are displayed as lines connecting co-ordinates corresponding to the positions in the determined ordering of interacting elements and the time value associated with the interaction. The visual clarity of such a display can be enhanced by selecting the criteria for ordering the elements.

Abstract: A data analysis system (1) for displaying data facilitating visual analysis of communication transaction is disclosed. The system includes a transactions database (3) operable to store transaction records (5) defining communication transactions and a processing module (11) operable to determine a hierarchy having a tree structure wherein leaf nodes in the lowest level of the hierarchy correspond to sources and destinations associated with communication transactions represented by transaction records 5) stored in the transactions database (5).

Abstract: The present invention provides a method implemented by a computer for generating an image on a display that represents a plurality of transactions as lines connecting points in the display indicative of a source and an origin for the respective transactions. For each of the lines, an anti-aliasing process is used to determine a coverage value for each pixel of the display that represents the extent to which the line covers each pixel, and a record of a cumulative coverage value for each pixel is maintained in an image buffer. When the lines have been rendered into the image buffer, the method comprises determining a maximum and a minimum of the cumulative coverage values stored in the image buffer, scaling the cumulative coverage value for each pixel, and rendering each pixel onto the display by using the scaled cumulative coverage value to determine a transparency for the pixel.

Abstract: A data analysis system (1) for displaying data facilitating visual analysis of communication transaction includes a transactions database (3) operable to cause representations of the communication transactions to be displayed on a display screen (13) by determining for each transaction a first set of control co-ordinates; determining for each transaction a set of control co-ordinates for drawing a straight line between co-ordinates associated with the source and destination associated with the communication transaction; calculating as a set of control co-ordinates for representing a transaction weighted averages of corresponding co-ordinates in the first and second set, weighted by a bundling factor; and representing each of the communication transaction as a line drawn utilizing the calculated control co-ordinates for each transaction.
