Abstract: The present invention relates to the field of network computing, and in particular to method and system for designing a Web Portal comprising a hierarchical structure of portal pages and portlets for accessing Web contents accessible via the Portal. A typical larger enterprise's portal contains large numbers, e.g., thousands of pages and portlets. Due to the complexity of an enterprise portal, manual administration is inefficient as it is time-consuming, error-prone and thus expensive. In order to overcome these disadvantages, it is proposed that a Portal according to the invention performs some mining of the portlet markup and/or that of the portlet description in order to autonomously compute and propose an enhanced portal content structure. This helps to provide a user-friendly content structure that reflects well the relationships between portlets.

Abstract: A system and associated method for data mining prediction is presented according to which the user selects a database table by means of a graphical user interface. Some records in the table are complete, while other records are incomplete. A subset of records of the database table is determined wherein each record of the subset contains a data value in the column selected for prediction. This subset of records is used to generate a model by means of a data mining algorithm, such as linear regression, radial basis function, decision tree or neural network methods. The resulting model is then utilized to predict the empty data fields in the column. After completing the prediction, the predicted values are entered into the column for display to the user.

Abstract: A method for sorting tablets at a rotary press for making tablets, comprising the following steps: the individual tablets are monitored with regard to at least one property of their condition during the pressing process, and a bad-signal is generated, if a tablet does not fulfil the property, and tablets which do not generate a bad-signal being good-tablets; the good-tablets are directed from a die plate of the rotary press into a good-channel; after a bad-signal has been generated, a bad-tablet is directed into a bad-channel by means of an air blast; by means of a further air stream, which is directed into the bad-channel, the bad-tablet is accelerated into the bad-channel whereby a returning to the die plate is avoided.

Abstract: A method and system for automatically detecting deviations in a data table comprising a multitude of records and a multitude of columns. A column of the data table is selected as a classification column and a classification tree is calculated with respect to the classification column. Each edge of the classification tree is associated with a predicate. The leaf nodes of the classification tree are associated with a leaf record set comprising the subset of records for which the class predicate comprising all predicates along a path from a root node of the classification tree to the leaf nodes evaluates to TRUE. Leaf nodes are associated with a leaf label representing an expected value in the classification column for the corresponding leaf record sets. From the leaf record sets all records deviating with respect to the corresponding classification column from the leaf label are determined as deviation sets.

Abstract: The present invention provides a method, a data processing system as well as a computer program product for optimizing process properties for workflows with failing activities. The invention makes use of monitoring occurrence of failure of each activity of a process model of a workflow and further monitoring properties that are associated to compensating activities that are required in order to repair the failure of an activity. The method makes explicit use of determining alternative execution sequences and selecting one of the plurality of alternative execution sequences of the process model, that optimizes the process property in case of failure of an activity of the process model. The process model itself remains unaffected and need not to be remodeled.

Abstract: Transactions within a process model are determined by grouping a set of individual process activities into a single transaction. This effectively reduces the processing overhead, and, therefore, improves the overall throughput and latency of the execution of the process model. The transaction is determined by performing an optimization procedure that takes into account the structure of the process model as well as various properties of the single process activities of the process model. Analysis of the properties of the process activities as well as application of the optimization procedure is performed dynamically during execution of the process model by a workflow engine.

Abstract: The present invention relates to a computerized method applicable to a set of parties connected via a network, and in particular it relates to a method and system for improving the search for services offered via said network. Said parties are Service Providers offering said services, Service Requesters needing said services, and Service Brokers maintaining information about said services and service providers. Said Service Brokers assist said Service Requestors in finding, for a particular service, the best services from the best Service Providers ranked by the importance for said Service Requestor. Obviously, the acceptance of a particular Service Broker by a particular Service Requestor depends on the capability of providing a (ranked) list of services that best meet the demands of a particular Service Requester.

Abstract: A system and method determine numerical representations for categorical data fields by taking advantage of the redundancy of the data records to allow automatic discovery of an order of the categories. A categorical data field is recoded by creating separate tables for each numerical data field occurring in the data records. The separate tables are sorted according to the numerical values of the respective data fields. The recoding of the categories is performed based on the average sort order of occurrences of the category in a specific sorted table. The standard deviation of the numerical codes provided by the categories is calculated for each of the separate recoding tables. The recoding table with the maximum standard deviation is selected as the recoding table to perform the recoding of the categories contained in the respective categorical data field of the data records.

Abstract: A user's comprehension of computer-generated data is enhanced by providing a visual representation of the data including a multi-character string. Before allowing the user to initiate a desired computer operation, the user is required to correctly enter characters matching the characters of the represented multi-character string. In one embodiment, the string representation is altered as matching characters are entered and recognized. In another embodiment, the multi-character string is presented initially and then masked before the user begins to enter characters. A character mask is removed each time a correct matching character is entered.

Abstract: A technique for rewarding a user's interaction behavior in a computer network environment, such as the Internet. A rewared is provided for following a hyperlink in a first document to a second document and then returning to the original document again. The reward can be provided in terms of (positively priced) information or payment in the form of bonus points or cash payment or access to computerized services and the like. The required information to effect the reward is stored in databases. The invention provides motivation for the user to definitely and intentionally return to the original document, rather than being lost to the owner of the original document as the user visits other web sites after visiting the second document.

Abstract: A method and system for presenting a group of objects in a ranking order. Objects are ranked according to user preferences by first observing the access order of a related group of objects in relation to a predetermined access hypothesis. A user preference model is then adapted to correspond to any deviations between the access order and the access hypothesis for the related group of objects. Next, object preferences are calculated for each of the objects to be ranked according to the preference model. The group of objects is then presented to the user in an order corresponding to the calculated object preferences. The preference model is adaptively updated, unbeknownst to the user, in the normal course of accessing the presented objects.
