| 20080243841 | Pattern searching methods and apparatuses - A computer-based method for identifying patterns in computer text using structures defining types of patterns which are to be identified, wherein a structure comprises one or more definition items, the method comprising assigning a weighting to each structure and each definition item; searching the computer text for a pattern to be identified on the basis of a particular structure, a pattern being provisionally identified if it matches the definition given by said particular structure; in a provisionally identified pattern, determining those of the definition items making up said particular structure that have been identified in the provisionally identified pattern; combining the weightings of the determined definition items and optionally, the weighting of the particular structure, to a single quantity; assessing whether the single quantity fulfils a given condition; depending on the result of said assessment, rejecting or confirming the provisionally identified pattern. | 10-02-2008 |
| 20090306964 | DATA DETECTION - A method of processing a sequence of characters, the method comprising converting the sequence of characters into a sequence of tokens so that each token comprises a lexeme and one of a plurality of token types. Each of the plurality of token types relates to at least one of a plurality of predetermined functions, wherein at least one said token type relates to multiple functions of the plurality of predetermined functions. | 12-10-2009 |
| 20090306965 | DATA DETECTION - An apparatus for processing a sequence of tokens to detect predetermined data, wherein each said token has a token type, and the predetermined data has a structure that comprises a predetermined sequence of token types, including at least one optional token type. The apparatus comprises a processor arranged to: provide a tree for detecting the predetermined data, the tree comprising a plurality of states, each said state being linked with at least one other state by a respective condition, the arrangement of linked states forming a plurality of paths; and compare the token types of the sequence of tokens to respective conditions in the tree to match the sequence of tokens to one or more paths in the tree, wherein the predetermined data can be detected without using an epsilon reduction to take account of said at least one optional token type. | 12-10-2009 |
| 20100100853 | MOTION CONTROLLED USER INTERFACE - A graphical user interface (GUI) is disclosed. The GUI comprises a three-dimensional virtual desktop surface. The GUI displays a view of the three-dimensional virtual desktop surface from a selected viewpoint and viewing angle and modifies at least one of the viewpoint and viewing angle based on detected head movements of a user. | 04-22-2010 |
| 20100121631 | DATA DETECTION - A method for detecting data in a sequence of characters or text using both a statistical engine and a pattern engine. The statistical engine is trained to recognize certain types of data and the pattern engine is programmed to recognize the grammatical pattern of certain types of data. The statistical engine may scan the sequence of characters to output first data, and the pattern engine may break down the first data into subsets of data. Alternatively, the statistical engine may output items that have a predetermined probability or greater of being a certain type of data and the pattern engine may then detect the data from the output items and/or remove incorrect information from the output items. | 05-13-2010 |
