Abstract: A method, a data network arrangement and a computer program product, by means of which a comparator can be implemented in a data network, in which comparator a possibility of online chat can also be utilized. The comparator user stores his evaluation of the properties included in the targets being evaluated in a database in the server in the data network by using a graphic one- or two-dimensional evaluation frame. In the comparator the comparator user's evaluations are compared to property values set for each target being evaluated. During the comparison the comparator analyses the data entered into the comparator by the comparator user against predetermined online chat threshold values. If even one online chat threshold value is exceeded, it is in the comparator according to the invention possible to offer the comparator user an online chat with the service provider's customer servant in order to support the decision-making.

Abstract: A method, a data network arrangement and a computer program product by which a comparator can be implemented in a data network. The user of the comparator stores his evaluation of the properties included in the targets to be evaluated in a database in the server in the data network using a graphic one- or two-dimensional evaluation frame. In the comparator the comparator user's evaluations are compared to property evaluations given by a reference user. When calculating the total accuracy percentage of the comparison the evaluations given by the comparator user are weighted with a weighting coefficient, which is obtained by normalizing first the importance evaluations of all the properties given by the reference user and by using the normalized importance evaluation of a certain property as the weighting coefficient for this property.

Abstract: A method, a data network arrangement, a computer program product and a server accomplish a service platform. The service platform has several customer interfaces whereby the customer can request a service in the service platform. The service platform prioritizes the received customer requests based on the prioritization value given to different customer events. A customer servant sees the customer requests in the order of importance that is based on the given prioritization value of each customer event. By utilizing the service platform the customer servant can concentrate on serving the customer requests in order of importance.

Abstract: The invention relates to a teamwork method and a computer system, using which the evaluations of a group about the features of different targets can be gathered and summarized. The system comprises a server (1), the workstation of the main user (3), a number of workstations for evaluators (4-7) and the software used by the web-browser. The main user formulates the inquiry. The server requests through email the evaluators to answer it. The evaluations are entered graphically using a two-dimensional table. The axes of the table present the dimensions to be evaluated. The program calculates normalization for the answers given so that the mean value is located in the origin. When a report is requested the server calculates the normalized mean-value figure, places the points in the two-dimensional table and adds ellipses around them, the dimensions of which present the deviation of the points in the direction in question.
