Abstract: A system for processing data comprising: a plurality of resource interfaces each of which is operable to access a corresponding underlying resource, and a processor unit for integrating data accessed from the underlying resources and controlling a user interface. The user interface is operable in use to permit a user to view all of the underlying resources currently accessible to the system and to select a plurality of these to form a subset comprising some, but not all, of the underlying resources from which to form an integrated view of the sub-set. The processor unit is operable to store the selection within a user selection store and to determine how to join the data from the selected underlying resources to generate an integrated view of the selected sub-set of underlying resources and to generate data for transmission to a device for displaying the generated view to the user.

Abstract: A concept dictionary is generated and/or updated in respect of an information system. The concept dictionary is used to assist in selecting queries and query terms for use in interrogating the information system. A lexical reference source is first used to generate queries semantically related to a query entered by a user, and the answers returned for each query are analyzed using a fuzzy processing technique to determine semantic relationships between the queries. The queries and the determined relationships are recorded in a concept dictionary for subsequent use.

Abstract: The performance of a computer-controlled system (1) operating under the control of a first process (2), is monitored (4) by comparison (5) with a predetermined set of requirements (15, 25), to identify whether the performance of the system (1) meets the predetermined requirements. If the performance does not meet those requirements, an alternative program (22) may be selected, or generated from program elements stored in a library (60), to replace the current controller process (2).

Abstract: A store of electronic documents is automatically searched by controlling a user interface to permit a user to enter a search term, carrying out a search using the search term, the documents returned by the search into a plurality of distinct categories, and controlling the user interface to present in a left-hand panel the plurality of distinct categories and in a right-hand panel the documents returned by the search, or references thereto, in a grouped manner such that documents, or references thereto, of a particular category are grouped together, wherein the categories are selected in dependence upon the search term.

Abstract: A method and apparatus are provided for generating, from an input set of documents, a word replaceability matrix defining semantic similarity between words occurring in the input document set. For each word, distinct word sequences of predetermined length are identified from the documents of the set, each word sequence being indicative of the context in which the word was used and, according to the relative frequency of occurrence of the identified word sequences for the word, fuzzy sets are generated for each word comprising membership values for corresponding groups of word sequences. For each pair of words occurring in the document set, their respective fuzzy sets are used to calculate the probability that the first word of a pair is semantically suitable as a replacement for the second word of the pair, these probabilities being collated to form a word similarity matrix for use in an improved method of determining document similarity and in information retrieval.

Abstract: The present invention provides a method of determining business intelligence in real time. A business process or operation can be defined by a number of inter-related business entities. The inter-relationship between the values associated with each business entity can be determined such that the values of strategic objectives, such as customer satisfaction, can be determined in accordance with changes in operational parameters, for example the number of active engineers, or external factors, such as the rate that calls are made to a help line.

Abstract: A method and apparatus for generating an index entry for a record in a semi-structured database involves analysing each field to identify an entry within each field and to identify a sequence of characters having a format corresponding to a predetermined format. Thereafter, the method and apparatus operate to generate an index entry for the identified entry, and for at least one field, define any characters not identified as an entry as a free text entry.
