Technologies of using information resources, the number of which is increasing every day, are one of the important issues of today. In this regard, including special attention is paid to improving the technology of searching and processing data based on semantic and fuzzy rules in corporate networks, database design and logical knowledge. The world conducts research work aimed at creating data retrieval systems, database design and semantic knowledge, creating and improving software modules and algorithms 118 IIUM Engineering Journal, Vol. 22, No. 1, 2021 Boltayevich and Bakhrom Ugli https://doi.org/10.31436/iiumej.v22i1.1389 for mining, search, data storage in corporate networks. In this regard, the important tasks are the design, development of models, methods for searching and processing data, creating software for building data retrieval systems in fuzzy and stochastic information environments of corporate networks. Modern technologies that do not replace many years of experience and highly qualified specialists, are designed to significantly improve the quality and efficiency of its work. This was discussed at the international forum held and dedicated to modern intellectual systems. As it was noted, the modern IT industry all over the world is going through a new stage of its development. The catalyst for this process is the latest technology that can solve problems that have traditionally been considered creative. The forum discussed trends in the development of modern intellectual systems, their implementation in various sectors of the economy, the health sector. With the independence of the republic, special attention is paid to the formation of a database of information resource centers (IRCs), on the creation of corporate information library systems, national content in raising the level of informatization of society based on intelligent management of hardware and software in information technologies. In this direction, the development of databases and software systems for logical search in data retrieval systems is included. The objectives for “... developing national content, improving the mechanisms for creating and promoting modern educational, scientific and educational information resources, multimedia products in the state language, meeting the needs of young people, ... introducing information and communication technologies ...” were defined. The implementation of this task, including the formation of electronic resources, the improvement of data mining systems, the development of a database of semantic data and knowledge in corporate information library systems, is one of the most important issues. In the world of creating electronic resources, modeling processes and creating high- performance control systems to study the issues of intelligent search and data processing, research is carried out in a number of priority areas, including the creation of intelligent software modules based on the theory of fuzzy sets in solving problems in the fields of computer science and library, creation of methods for analyzing, searching and storing data based on models and methods of Data mining and Text mining, Big Data, development of methods and algorithms for integrating systems data retrieval, creation of algorithms, methods for processing and searching full texts, creating databases of aggregate data of corporate information library systems, creating methods and algorithms for processing requests for artificial and natural languages, creating a knowledge base, a semantic core based on the principles of SMART and SEO, developing software and data retrieval models based on local language. Studies have shown that issues related to information retrieval, the structure and properties of data, the formation and processing of queries, the creation of a semantic core, the identification of electronic resources rating, the development of models and methods for intelligent search, the presentation and processing of data in fuzzy and stochastic information environments of corporate information biotech systems are not well understood. The purpose of the research is the development of models, methods for searching and processing data in fuzzy and stochastic information environments, as well as the creation of software for corporate information library systems. 119 IIUM Engineering Journal, Vol. 22, No. 1, 2021 Boltayevich and Bakhrom Ugli https://doi.org/10.31436/iiumej.v22i1.1389 2. MAIN CHAPTER Methods of forming queries, determining the rating and elements of data search in the corporate network are devoted to the questions of forming queries, determining the rating and elements of searching in fuzzy and stochastic information environments (NSNS). A “search module” is a subsystem that, upon request, provides the most current ordered set of electronic resources, equipped with a user-friendly interface, including a database and statistical data. The search module in the corporate network consists of two main elements that are independent of each other: an indexing element and a search element. The user sees only the capabilities of the search item and uses it. The indexing element is used to create the appropriate form for the effective presentation of information when searching for the necessary data in the data retrieval system (DPS). Suppose that in the database are consistently given and are in the segment V = [1, n], N={0, 1, 2, 3, …} with DosID identifiers with the set V, which has n electronic resources: a) A quote (or reference) is a pair of ordinal electronic resources. ( ) 2, Vi j  . i - incoming link and j outbound link electronic resource. In the set V between the electronic resources from all the links we form the E set, the graph directed to the links can be called reference graphs G = (V,E). b) For example, G = (V,E) in this case the graph is the final set of vertices, E V V=  and i V , denote ( )I i the incoming set of links, and ( )O i the outgoing set of links denote as, then: ( ) ( ) | ,,I i e E e j Vi j=  =  , ( ) ( ) | ,,I i e E e j Vi j=  =  (1) c) If ( )O i and ( )I i do not exist and, then they are denoted as in this case   , the rating of the electronic resource i V equals 0. d) No electronic resource can provide its inbound links ( )I i and outbound links ( )O i to these links. The rating of incoming links rI and outgoing links rO is determined as follows: ( ) ( ) 1 ( ( )) ( ) I ii ri r count I i Doc I I iI i ==   ( ) ( ( )) ( ) r count O i O i O O i =  (2) Here ( ( ))count I i - is the number of incoming, ( ( ))count O i - the number of all outgoing links. Using the expression given above (2), we determine the method of preliminary rating of an electronic resource using (3) an expression. ( ) / 2r r rD I O= + (3) Expression (2) allows the definition of electronic resources with a high rating and select a set that is recognized as relevant based on the identification of the rating of electronic resources in corporate information library systems (ICBS). 120 IIUM Engineering Journal, Vol. 22, No. 1, 2021 Boltayevich and Bakhrom Ugli https://doi.org/10.31436/iiumej.v22i1.1389 Suppose that  iq q= a lot of requests and given to iq the corresponding to a variety of electronic resources  i ijR r= , 1... dj M= 1... qj N= . Here dM – is the number of electronic resources viewed in the system, Nq – is the number of requests in the system. The method of logical-semantic search for a couple of queries, we will write as follows. ( , ) | j i i j i j j R R f q q q q R  = = (4) Here, a b - denotes the relation and similarity of a with respect to b. j i j R R R - the condition must be relevant. Rule 1: If 0i jq q = , then in this case iq - is not semantically related to jq , and is also considered not similar to each other. Rule 2: If 1i jq q = , then in this case it is considered that iq , jq is completely semantically related and the similarity 1 is considered ( iq exactly similar). Rule 3: If the expression (4) is equal i j= , then in this case 1i jq q = it is considered semantically related, the similarity is 1 (it is exactly the same). Rule 4: If 0 | 1i jq q  , then iq in this case, it is considered that semantically equal jq and the similarity is calculated by the expression (4). The method of logical-semantic search (4) for all queries, we write as follows: 1 2 1 1 1 1 ( , ,..., ) | q q q q q N N N N j i N i j j i j i j R R f q q q q q R= = = =  = =  (5) here ∑ is the union of the elements of the set. (5) the expression allows you to create a base of semantic knowledge in the data retrieval system (DPS). Creating models, methods, and software for searching and processing data in fuzzy information environments, using the theory of fuzzy sets and using the linguistic variable model, defines the method for developing fuzzy queries in the data retrieval system (PDS) as follows: 1) () – defined linguistic variable; 2) T() – we define a linguistically similar variable of a fuzzy set of terms; 3) X – for fuzzy sets of terms, we determine the set of values; 4) G() – defined in the set of fuzzy terms, characterized by logical and modifier outputs; 5) x – X defines the membership function of the set. When designing a parametric membership function, the set −x X is the linguistic variable of the corresponding object characteristic, the parametric design  –method of the membership function is an important element in the intellectualization capabilities of the data retrieval system (PDS). x – in the membership function, enter 4 parameters and give the following definition: 121 IIUM Engineering Journal, Vol. 22, No. 1, 2021 Boltayevich and Bakhrom Ugli https://doi.org/10.31436/iiumej.v22i1.1389 Proposition 5: If a, b, c, d parameters are taken from X – the set of values, then in this case the function is considered to be x(a,b,c,d) the membership function of the set of values - X. Proposition 6: In the membership function x(a,b,c,d), the parameters a, b, c, d among themselves must be in ascending order. So one of the conditions a < b or b < c or c < d must be constantly met. Proposition 7: T() – the parameters of the membership function for each term of the set of fuzzy terms corresponding to linguistic variables T(), at least one distinguishing parameter must be introduced. It is recommended to use the choice of classes for the selection of membership functions corresponding to the linguistic variables of a fuzzy set in intelligent search and processing in a fuzzy information environment. When intelligently searching for data in a fuzzy information environment of corporate information library systems, the main problem is the creation and management of the semantic core. We give the definition of a semantic core for intelligent search and data processing. In a fuzzy information environment: The semantic core is a set of relationships recognized as relevant, relevant in content and essence to normalized terms and electronic inquiry. Based on this definition, 3 methods have been developed for creating the semantic core of data retrieval systems in a fuzzy information environment. These include: • Automatic construction of the semantic core as a result of search and processing. • Creating a semantic core by processing the citation of links, data in electronic resources. • Creating a semantic core with the help of expert groups. This method is carried out in version 2. a) Creation of a semantic core by an expert by creating queries corresponding to an electronic resource. b) Expert processing of the existing semantic core, cancellation, modification, creation by it of the relationship of the request with the electronic resource, if necessary. A model of the semantic core, based on the implementation of the control of the semantic core and 3 algorithms of methods for creating a semantic core, has been developed. To determine the relevance of the semantic core model 4 properties have been added to the semantic core. If in property 1 there is a semantic link of the electronic resource and the query is 1, otherwise it takes the value 0, property 2 activates N - the total number of links, property 3 - m - the number of link-references. In a fuzzy information environment for intelligent search and data processing in the development of models and rules for fuzzy search, the core of the knowledge base will form a fuzzy query q in a variety of fuzzy queries q* (6) to form the rule condition as follows:  * * * *: , ,...,1 2f q q q q qn→ = (6) 122 IIUM Engineering Journal, Vol. 22, No. 1, 2021 Boltayevich and Bakhrom Ugli https://doi.org/10.31436/iiumej.v22i1.1389 in this case, i q  - 1i q  the term consists of a fuzzy pair of terms 2i q  and can be defined as 1 2 | i i q q   , and, 1...i n= , 2 2 i n q    , 2i q  - 2i q  is the number of fuzzy terms. Conditions of the rule for the logical action "And" and 1 q  a pair of terms (6) we write as follows: 1 * * * * * 1 11 12 1 1, 12 ( ) ( ) ( ) ( ( )) x q q and q d and q t and a q= = = = (7) where * 1 ( )q q= - 1q  - q – is the pairing or non-pairing of the terms that make up the query, * 11 ( )q d= - the semantic relation of the electronic resource d and term, 11 q  , * * 12 ( )q t= - the presence or absence in the set of fuzzy terms t* of a database of fuzzy data 12 q  , * 12 ( ( )) x a q= - * 11 ( )q d= , the weight а and the membership or non- membership of the values of membership functions of fuzzy terms 12 q  . Using this condition (7) we write as follows. Optimally, the fuzzy rules are based on the Mamdani method for intelligent data search in the data retrieval system. ( )* * * * *1 2 , 2 1 ( ) ( ) ( ) ( ( )) i n i i i i i x i i q q and q d and q t И a q R = = = = = → (8) If, on the basis of fuzzy rules, to write the set D of electronic resources in the knowledge base of rule (8), we obtain a system of fuzzy rules  1 2, ,..., mD d d d= , m - the number of electronic resources in the database. We introduce the concept of the knowledge base kernel for the definition method, a fuzzy term and modifier, parameters corresponding to the membership functions that have been developed and are constantly updated with the help of expert experts. The algorithm for the development of the knowledge base kernel, the IDEF1x model, and relationships in the model have been developed. For the formation of a variety of electronic resources that meet the requirements in a fuzzy information environment, IDEF0 models have been developed that describe the functional structure and functionality of category 3 related tools to create a knowledge base based on the knowledge base, semantic core, and processing fuzzy requests. Creation and implementation of software for searching and processing data in the corporate network, is devoted to the development of technology and architecture of FSV, composite modules and models, for the effective operation of search modules in corporate information-library environments it is necessary to have several basic steps. 123 IIUM Engineering Journal, Vol. 22, No. 1, 2021 Boltayevich and Bakhrom Ugli https://doi.org/10.31436/iiumej.v22i1.1389 Fig. 1: IDEF1x core model knowledge base. It is enough to have 3 basic stages of the modules of the search box in the data retrieval system of a multi-profile corporate network. These include: 1. (F) - method of presenting the request, i.e. method of forming the expression of the information needs of the user system. 2. (S) - the function of the correspondence of the electronic resource to the request, i.e. the degree of compliance with the query and the found electronic resource. 3. (V) - method of presenting electronic resources. Fig. 2: Architecture of FSV technology for processing data. Combining these three stages for models, methods and software modules of the AML, we call FSV technology (FSV platform, FSV Framework). 124 IIUM Engineering Journal, Vol. 22, No. 1, 2021 Boltayevich and Bakhrom Ugli https://doi.org/10.31436/iiumej.v22i1.1389 FSV technology is an instrumental software platform based on a client-server architecture, integration and modification of models, methods and algorithms for searching and processing data in the information environment of corporate networks. The following architecture has been developed for the FSV technology proposed for the search index in data retrieval systems. In the development of the functional structure and IDEF models of the instrumental software module for query processing corporate networks request processing is divided into 2 stages. Fig. 3: Architecture of FSV technology for intellectual research. At stage I, requests are created in natural language, based on the request processing methods, artificially created requests, based on the UI (User interface) methods. The second stage, which is a recurrent sequence, is carried out by clearing additional and auxiliary terms, determining the type of query, creating indices of logical and fuzzy terms, of the zonal field. When creating IDEF models and functional structure of a software search and presentation software module. In the corporate network, an IDEF0 model was developed based on the methods, data retrieval system models in fuzzy and stochastic environments, traditional search, and S-ER matching process. Presentation V includes the processes of receiving a set of electronic resources, choosing a presentation method, determining the type of UI, providing constraints and filters and representing the set based on them, determining and controlling calls in the user’s electronic resources. Fig. 4: Search results and data processing for the parameter "Speed". 125 IIUM Engineering Journal, Vol. 22, No. 1, 2021 Boltayevich and Bakhrom Ugli https://doi.org/10.31436/iiumej.v22i1.1389 FSV technology is integrated into such systems as: “ARMAT ++” - an automated system of information resource centers, “Mobile-Library” - mobile software on library resources, “vLibrary” - a virtual library of written cultural heritage of Turkic peoples of Central Asia of the XIX century (Kazakhstan). For the experiment in MARC21 format, you can use the ISO2709 data exchange standard when exchanging data in corporate information library systems. Therefore, more than 50,000 titles of various electronic resources and full texts were chosen. For comparison and analysis results, such parameters as “Speed”, “Number of found data”, “Average relevance value” were selected and their results are given in the following figures (Fig. 3 and Fig. 4). Fig. 5. Search results and data processing for the parameter "Average relevance". The results of the experiment show that high speed provides the user with, firstly, superfluous information, secondly, it is very difficult to satisfy the information needs, i.e. need to analyze a lot of data. Although the search takes more time, but finding the necessary data indicates the effectiveness of search systems, since the analysis and limitation of redundant information saves 25%, sometimes up to 50% of the time of users. The implementation of the results. Based on the software "ARMAT ++", created on the basis of FSV technology, models, methods of searching and processing data in fuzzy and stochastic information media: • a method for determining a preliminary rating of an electronic resource based on references, a software module and an algorithm for designing parametric membership functions based on linguistic variables for fuzzy user requests, a software module, a method and algorithm for creating a knowledge base were introduced into the corporate networks of the main library of the Academy of Sciences (reference dated October 30 2017 No. 33-8 / 7293 of the Ministry for the Development of Information Technologies and Communications).
