The paper analyzes the main trends of search the basic direction and identifying the priority of electronic documents handling in the Internet. The technical principles of construction of information retrieval system and ability to use linguistic processor and neural networks for solving problems determining the importance of consideration the input documents were grounded. The object of the study was the decision support systems designed to determine priority of review incoming documents. The proposed system can be actively used in information support blocks of inductive technology of system information-analytical research
