Abstract: A document is stored in and retrieved from a repository being indexed by a search engine by applying to each document a first classification based on a profile of a user who is likely to access the repository. A query formulated by the user to the search engine results in the engine producing a list of references of documents. The list of references is reduced by eliminating from the lists the documents and references which do not correspond to the user's profile. A second classification level, representative of the particular nature of the problem to which the document refers, is performed. Automatic tagging and labeling mechanisms improve the repository partitioning.

Abstract: A process for accelerating search in a repository of resources indexed by a search engine. Each resource is classified in accordance with a least a first classification level. The process comprises the steps of: monitoring the access to said repository by the users and creating a shortcut index of resources which are flagged by the users in order to develop experience from the use of the repository; processing each new query entered by one user by a first preliminary searching within said shortcut index, followed by a standard search within the whole repository.

Abstract: A method of monitoring the condition of a computer system, comprising receiving performance data from the system, processing the data to estimate the likelihood of a deterioration in the condition of the system and providing an output which is dependent upon the estimated likelihood.
