Problem number 1
Conditions: In the development of EC attended by representatives of the following specialties:
Answer student: an expert in the problem domain, which will solve the problem of ES
knowledge engineer - an expert on the development of ES (it uses a technology called technology methods (methods) knowledge engineering)
programmer to develop tools (ICs) designed to accelerate development of ES
expert in the field of accounting software

Problem number 2
Terms: To develop ES was possible for this application, you need to simultaneously perform at least the following requirements:
Learner Response: There are experts in the field, which solve the problem much better than novice experts; Experts agree on the evaluation of the proposed solutions, otherwise it will be impossible to assess the quality of the ES developed
Experts are able to verbalize (expressed in natural language) and explain the methods they use, otherwise it is difficult to count on the fact that the expert knowledge will be "removed" and invested in the EC; solution of the problem only requires reasoning, not actions
the task should not be too difficult (ie, its decision should take an expert a few hours or days, not weeks); Although the problem and should not be expressed in a formal form, but still must be treated sufficiently to "clear" and structured area, i.e. We should be allocated to basic concepts, relationships and well-known (at least to the expert) methods of obtaining the solution of problem
solution of the problem should largely use "common sense" (ie, a wide range of general knowledge about the world and the way of its functioning, which knows and can use any normal person), because such knowledge is not yet possible (in sufficient quantity ) to invest in artificial intelligence
All of the above

Problem number 3
Conditions: The application corresponds to the methods of ES if solvable problem has a collection of the following characteristics:
Student Response: the task can be solved naturally through manipulation of symbols (i.e., via symbolic reasoning) rather than manipulation of the numbers, as is customary in mathematical techniques and traditional programming
task should be heuristic, not algorithmic nature, i.e. its decision should require the use of heuristic rules. Tasks that may be reliably resolved (subject to the limitations specified) using some formal procedures are not suitable for application ES
task must be sufficiently complex to justify the development costs of ES. However, it should not be too difficult (decision takes an expert watch, not weeks) to ES can solve it
task must be narrow enough to be solved by methods of ES, and practical significance
All of the above

Problem number 4
Terms: At the stage of identification ...
Answer student: identify the tasks to be solved, the design goals are identified, defined by experts and user types
held a substantive analysis of the problem areas identified concepts used and their relationship, defined methods for solving problems
selected IP and determined ways of presenting all kinds of knowledge, formalized the basic concepts
determines how the interpretation of knowledge, simulated operation of the system, evaluate the adequacy of the objectives fixed concepts, methods, means of knowledge representation and manipulation
carried out by the expert knowledge base content

Problem number 5
Terms: The dependence of the composition of the knowledge on the requirements of the user is shown in the following:
Answer student: what tasks (from a common set of problems) and what data the user wants to decide; What are the preferred methods and methods of solution
Under no restrictions on the number of results and methods of making the problem to be solved
What are the requirements for the language of communication and dialogue
what degree of generality (specifi
