In the global Internet due to the ever increasing amount of data is becoming increasingly important problem to improve the quality of search and navigation systems. This is due to the fact that users are increasingly common complication of finding relevant information not only when referring to search engines, but also on the resources of great informational content. Intelligent site with a decision support system (DSS)  improve the quality of information retrieval on the Internet. Decision Support System DSS . a software system designed to facilitate the work of people who perform data analysis . DSS as part of the site allows you to perform predictive analysis of user data to improve information retrieval on the Internet. There are three main tasks to be solved in DSS: data entry, data storage and data analysis. As part of the development of intellectual Site (IS) DSS reveals hidden patterns and relationships  between the available data about the user, thereby gaining possible data based on aggregate data and data based on assumptions. The main objective of conventional DSS . give analysts a tool to perform data analysis, ie, the system does not generate the correct solution, but only provides the data in the appropriate form (tables, graphs, etc.). However, there is the possibility of creating intelligent DSS, which are characterized by the presence of functions that implement specific mental abilities of a person. This type of DSS is considered as a module IC . Over the degree of ?gintelligence?h data in the analysis, there are three classes of task analysis : Information retrieval . DSS scans required data quickly and Analysis . DSS produces grouping and summarizing data in a form, intellectual . DSS scans functional and logical patterns in historical data, building models and rules that explain the patterns found. Regarding IS it search for data based on aggregate data and data based on assumptions of data [...]
