RESEARCH LINES
(1) Development of the method and mechanism for effective search of the set of the relevant answers to the questions.
(2) Technology development for the creation and support of the catalog service of the information fund for providing an efficient search of the answers to the questions.
(3) Software development cataloguer workstation for the structuring of the information fund.
REALIZATION IDEAS OF
RESEARCH LINES
The method basis is a way to describe the scientific and technical information by set of logic-semantic networks Question-Answer-Reaction (LSN QAR).
The basis for the search engine are: motion way along LSN, controlled by the user; choice of LSN nodes (questions or answers) based
on an ontological model of user question. The basis of the technology is a way of the
description of the subject domain by LSN QAR set.Mechanism of technology is a workstation of
the cataloguer (LSN QAR developer)
Formal Structure of Question, Answer, Reaction
The logical structure of the question (Q):QUESTION = {QUESTION THEME (QT), QUESTION
CONTENT (QC), QUESTION VOLUME (QV)}
The logical structure of the answer (A):ANSWER = {ANSWER THEME (AT), ANSWER CONTENT
(AC), ANSWER VOLUME (AV)}
The logical structure of the reaction (R):REACTION= {REACTION THEME (RT), REACTION CONTENT
(RC), REACTION VOLUME (RV)}
Logic-Semantic Network Question-Answer-ReactionLogic-semantic network a set of the questions, answers and relationships between them forming an uniform system.Question query expressed in the interrogative sentence aimed at
the development, refinement or supplement of the knowledge.Answer a realization the cognitive function of the question in the
form of the new obtained judgment. Answer must be built in accordance with the content and structure of the asked question. Only in this case, the answer is regarded as relevant.
Reaction a semantic description of the question and answer.Types of reactions:1. Question Reaction a description of the datum question (to understand the enviroment and causes of the question and to establish thesemantic adequacy with the answer scope).2. Answer Reaction a description of the answer scope (to understand the question semantics and relationship with answer).
Reaction Example (1)Logical unit Question-Answer-Reaction: Question 1 (Q1). What is a JAVA?
Question 1 Reaction 1 (QR11). With respect pronunciation formed two different standards - borrowed from the English / dʒɑ:və / and traditional «Ява» (on russian), corresponding to the traditional pronunciation of the Java name island.
Question 1 Reaction 2 (QR12). Java (Indonesian: Jawa) is an island of
Indonesia with a population of 135 million. Square 132 000 k2…
Question 1 Reaction 3 (QR13). Slide show, photo-collage with the views of Java island.
Reaction Example (2)Answer 1 to Question 1 (A11). Java – an object-
oriented programming language developed by Sun Microsystems.Reaction 1 of the Answer 1 to the Question 1 (RA11). Why
is the language called JAVA? There is a version that language got its name from coffee grown on
the same island. As you know, this drink is hot like some programmers.
Therefore, a cup of steaming coffee is displayed on logo.
Reaction Example (3)
Reaction 2 of the Answer 1 to the Question 1 (R2A11). Sun Microsystems, Inc (now part of Oracle Corporation) — U.S. company that produces software and hardware…
Answer 2 to Question 1. Java — not only the language itself, but also a platform for development and execution of the applications based on this language.

Analysis Method of Scientific Texts The document is studied by the expert in terms of:
1. Semantic matching title and content;2. Set of filters:
Filter 1 (F1) - General Part. F1 includes an analysis of the problem, its history, overview, topicality.Filter 2 (F2) - Author concept. F2 includes new terms introduced by the authors, traditional terms with the author's interpretation, the narrowing semantics.Filter 3 (F3) - Examples and illustrations. To clarify difficult places in the text, reduce the text size under stringent restrictions on the volume.Filter 4 (F4) - The idea of the author. Describes and explains the author's main idea.
3. Markup text (formulation of the basic questions, answers and reactions).

Summary• It’s proposed: "Catalog Service" creation and support for the funds-corpuses, Question-Answer Navigator creation that provides such features: - the ability of the refinement and deepening of the understanding the question
meaning; - the ability of the refining, deepening, expansion of the knowledge or the
obtaining a new knowledge
during the answer to question search process.• Realization of such "Catalog Service" and Navigator allows to
study the DL content by the natural mode for the human: refinement, generalization and obtaining a new knowledge U question-answer mode.
• The main problem of the proposed question-answer system is a maximal automation of the process of the creation and support of the fund service catalog.
