Introduction

The current development of the Internet contributes to information needs increasing such as production factor or strategic resource. It also activates the new implementation forms of information services [ 1-9 ]. Informational product (commercial content) is documented information, prepared according to user needs and designed to meet them [ 10-13 ]. Actions for commercial content user providing are information services. Internet market is set of economic, legal, organizational and programmatic relations with the sale/purchase of information products/services between producers/suppliers and users. The concept of commercial content is defined as information resource in filling in the electronic content commerce systems (ECCS); object of business processes in ECCS, such as paper, software, books, etc.; structured set of logically complete information to which the relationship between the user and ECCS; a set of data without predetermined patterns that exist only in electronic form; information for commercial purpose which indivisible in time; the main factor in the region formation of the ECCS functioning and purpose [ 14-21 ]. Information resources are a collection of documents, or arrays of instruments in information systems (libraries, archives, collections, data banks, repositories, museum storages, etc.), which are subject to ECCS. Content is a set of information resources and products that are stored in an environment information system (IS) of Virtual Library and available for application users of the system [ 22-26 ]. Content is these data without pre-defined structure of visual presentation as opposed to structured data that usually are managed by DBMS. The development of information technology led to the fact that in the modern world economy it has become a key concept of content is an important element of the driving force of economic growth and social change. The successful development and growth of Internet e-commerce content once again proved that the information economy is dynamic and profitable. There are three fundamental content definitions [ 18-29 ]: 1. 2. 3.

any significant information content IS (e.g., text, graphics, multimedia); part of the message, which is not processed and does not change during transmission; content of the document data (other than attributes) that contains text, images, videos, audio, scripts, programs, or any other similar material content of solid media.

A variety of content commercial content is this product information or content of Web-site, Internet publishing, market research, consulting services, which are subject to business processes ECCS. Content Management System (CMS) is a system that meets a specific set of requirements and is designed for content management. Such systems are used for storage and publication of a large number of documents, images, music or videos. Another case of such systems is ECCS [ 30-36 ]. Such CMS can manage text and image content, giving user’s convenient storage tools and information publications. Management System Web-content is designed to generate content within the portal and have the same problem (dynamic collection, content caching, its safety, etc.) and other kinds of Web-applications. The initial information for constructing mathematical models of processes are functioning ECCS data on purpose and working conditions of CMS [ 18-21 ]. This information defines the main purpose of modeling ECCS and allows us to formulate requirements on formal models of ECCS and models of content management. 2

Formal ECCS model

Formal ECCS model S  X ,C,V , H ,Y is a tuple of variables that describe the process of the system (Table 1).

The values xi , cr , vl , hk , y j are elements of subsets that are disjoint and contain deterministic and stochastic components [ 18-21 ]. Inbox influences xi , influences the flow of content cr , the external environment vl and internal system parameters hk are independent, and source information y j systems are dependent variables [18     21]. The process of operation S is described by a function y t   f  x, c, v, h, t  . 3

Comparative characteristic of content management

A description models built of content flow is important and remains unexplored. When considering in [ 18-21 ] the dynamics of thematic content streams found that models are limited, opening the way for further research. In Table 2, comparative characteristics of content management are presented, which describe the process of identifying and aging research (actual) content rather than defining the stages of the content lifecycle (creation, management, implementation). Existing CMS do not support full content lifecycle (creation, management, implementation) streams and do not solve the fundamental problems of information resources processing – content development and implementation. Formal ECCS model does not disclose the content management mechanisms. Formal models of content management appointment only determine the aging process (actual) content stream, and some of them (logistics, analytical) and thematic content stream. They do not solve the problem of the content formation, implementation and not solve all problems, content management, for example, submitting a set of content by end users according to their inquiry, history or information portfolio, automatic digests creation, information portraits, automatic detection of thematic subjects, the construction of correlation tables of communication concepts, calculation of ratings terms, gathering information from different sources and its format, identifying keywords and concepts of content, automatic categorization of content, identifying duplication of content, selective dissemination of content. A basic lack of formal models of content management is the lack of links between input information, content and output information in ECCS. The general principles of ECCS architecture design allow to realize technology of a information resources processing effective. A formal model of electronic content commerce systems is six elements as

Selective distribution list content CDs  sup(CCt ) depends on the level of demand for this content. Associative rules forming the list of contents consists of a list of content CCt (original list) and the list of content selected from the original list CDs , so CCt  CDs . Formation of association rules is formation content formed as a result of initial and original lists. The probability of formation of association rules is the probability with which the content of the original list CCt will appear in the content of the original list CDs in the database, so cf (CCt  CDs )  sup(CCt  CDs ) .

Models of resource management. Main tasks of the content management module are creation, rotation of the database and providing access to it, forming the operational and retrospective database; personalization of users, storing personal user queries and sources of statistics, ensuring the search in database, generation of output forms, information interaction with other DB.

Content analysis of textual information

The system provides the introduction, the content categories choice, content ordering, mutual settlements implementation, the order tracing. There are different classes of ECCS and models variety of such systems. Nevertheless the article highlights the main patterns of transition from the processes of information resources formation to them support. Accordingly formal models of information resources formation, management and maintenance were proposed. These models allow realizing the ECCS architecture optimally. The complex method of the content forming provides a information gathering from different Web-site and its formatting; content keywords and concepts identify; automatic categorization of content; content duplication identify; selective dissemination of content. Operative method of the content management provides database formation and access to it; operational and retrospective database formation; database rotation; user experience personalized; personal needs and sources maintaining; counting; statistical analysis of the users operation in the system; content search in the database; initial forms generation; information interaction with the database of other subsystems. Complex method of content support provides information portraits formation; digests formation; thematic content identification; concepts relationship tables construction; concepts ratings calculation; new developments identification, their tracking and clustering. The fully functional ECCS is characterized complex system of interrelated operations, methods, techniques. The annotations database creating is a search images database creating of original content and their clustering (to the content group formation with close on some criteria of search images). Annotation base (search pattern of clusters used in the search process) is associated with the cluster base. Each entry corresponds to its specified cluster and description containing. This description is made of automatic abstracting methods.

Content analysis of textual information allows determine the signs prevalence of researched content in ECCS. It is important not as an absolute, but the relative importance of attributes, i.e. characteristics of the place (shares) among other features. For example, this is the percentage of forum users discussion of economic Issues concerning political or the percentage of positive comments on articles regarding the negative and in respect of all comments on this category of articles in online newspapers. The degree of correlation between the features in the texts provides empirical data to understand of the functional links between elements reflected in the texts reality eg the audience mood determination of online newspaper about the economic or political situation in the country and/or world. If there are texts that have chronological sequence received number fixed in time portraits of the investigated reality (change in demand for a content category according to the season, such as winter read more fiction and detective stories – summer) or the target audience portraits (change in demand for a content category according to the article, for example, demand for political articles before the election). This allows to put forward hypotheses of the prognostic character about the system functioning. In digest formation using content analysis with regard to frequency weights of words from the concepts dictionary generated. The digest formation consists are algorithms of the concepts dictionary forming, of the content duplicate definition and of the digest create (alg. 1).

Algorithm 1. A digest create.

Stage 1. Content Select based on its weight.

Step 1. Digest size C input.

Step 2. The algorithm 1 implementation.

Step 3. The weight consistent determine of each content as the weights sum of its individual words that W   wi .

Step 4. The input content stream sort from the weights values.

Step 5. Meaningful content duplicates definition for statistical criterion of text uniqueness U  0,9 .

Step 6. Content filter of unsuitable for digests building (when W  l , where l – Content removal threshold value by the self-education rules of content structuring and moderating) and statistically substantial duplicates.

Step 7. The choice of V  q content with greater weight where q  const and the moderator given.

Stage 2. Digest text construction of selected content.

Step 1. Dictionary construction of selected content.

Step 2. Content analysis application to the text (Table 1).

Step 3. Sentences filtration that do not meet the semantic rules of content structuring and moderating.

Step 4. Hypertext presentation formation of digest, its contents and a link to the original source.

Stage 3. Generated text edit of digest.

Step 1. The check amount of generated content ci . If ci  C , then step 2, otherwise stage 4.

Step 2. Content delete from the input stream that is used to the digest formation. Step 3. Steps 1-2 implementation.

Step 4. Resulting append to the pre-formed digest and move to step 1.

Stage 4. Digest text formation as a separate content and its maintaining in the database with reference on the source.

Stage characteristics of content analysis Using a set of defined criteria which corresponds to each content: given type of source; one type of content; given the parties which involved in the communication process; message size matched (minimum / length); messages appearance frequency; messages distributing method; messages distribution space; messages appearance time, etc.

The selected set of content is formed on the criteria a limited sampling from a larger array of information. Its forming using the procedure from a set of precisely defined actions for processing without any changes of all objects study.

Compliance with strict requirements concerning the linguistic units choice for content analysis: large enough to interpret meaning; small enough not to interpret the many meanings; easily identified; units number is large enough for sampling. When taking of the themes analysis unit take into account that its size does not go beyond a paragraph; new theme arises with the new characteristics appearance of linguistic units.

Computing units may coincide with semantic units, or have specific characteristics.In the first case, the analysis procedure is to the frequency calculate of the selected content unit use. Otherwise, the researcher proposes computation unit (physical length of the texts; text area, filled with informative units; the number of rows, paragraphs, characters, columns in text; the file size / type; pictures number with a certain content and story) based on the analyzed material and research purposes.

Standard techniques for classification of selected groups of mathematical statistics and probability theory formulas.

This includes all extracted text fragments. When forming conclusions do not take into account of the some results, without exception all. Here are identified and measured the text characteristics. They allow drawing conclusions about that wanted to emphasize or hide its author. Or they predict changes in demand for content based statistical set of calculated coefficients for the time period of specified category.

Content with new themes is the new groups basis of interdependent content in thematic stories identifying with the following procedures:  control within the system is level destination of user access to different content;  content integration is content moving to a new decision;  content support of various types is content storage and sorting in a central repository;  detailed documentation and context-intelligent help support;  rating system of site articles evaluation;  template changes is general formatting changes to the content of the part site reflects the entire site;  workflow support is automated business processes create for specific content;  content marking is new categories and markers adding to content before / after saving;  version control is new versions creating, view and return to the previous versions of content;  content analysis of text streams in the system;  visual administration tool is easy authors management of content, without resorting to programming, typically implemented using HTML-forms;  concepts relationship tables construction.

The concepts ratings calculation is based on procedure for results calculating of content analysis, taking into account the ratio coefficient c of positive and negative (for the selected item) estimates, opinions, arguments, as described in the user comments on the content ECCS. In Table 6 presents a available stages list of the commercial content lifecycle on the developed system. In Table 2 also presented the operation results of the developed systems from Google Analytics. They imply that the presence of all stages of the content lifecycle on the site significantly increases the amount of visits and unique users.

The lifecycle model of commercial content implement in the form of contentmonitoring complexes to content collection from data various sources and provide a content database according to the users information needs. As a result, content harvesting and primary processing its lead to a single format, classified according to the Categories and he is credited tags with keywords. This facilitates the commercial content management process implementation. In text analyzing explore its layered structure: the source text as a characters linear sequence; morphological structure linear sequence, statements linear sequence, related unity net. The text preliminary study provides for the text division into individual tokens that carry out the finite automata method. Entry information is text in natural language text as a characters sequence, and output information – analyzed text partition, sentences and tokens table. There is the following relationship: the more unique content in the electronic content commerce systems, the more the visitor’s information resource in its system. Commercial content support subsystem reduces the time to fill out unique content an information resource and increases the volume in a short time at this unique content in information resources and the queries number from search engines. These data take into account when creating or updating information resource and improve the electronic content commerce systems architecture. The service of the statistics of visits to the information resource of the ECCS allows us to estimate the increase in the volume of sales of content from the direct proportional dependence of the increase in the number of visits to the information resource, the number of regular users, and the promise of marketing activities (Figures 2).

Discussion

The presence of different types ECCS increases in sales of goods and / or services a regular user of 9%, the active involvement of unique visitors, potential users and expanding the boundaries of the target and regional audience by 11%, page views by 12%, time of visit information resources on 7%. So cumulative and median filtering for information resource victana.lviv.ua visit pages per session is shown in Fig. 3. For an agglomeration hierarchical cluster analysis, it is advisable to choose the strategy of the "closest neighbor" for unification (since the proximity matrix consists of only 5 objects). The distance between the two groups is defined as the distance between the two closest elements of these groups (Figure 4). This strategy is monotonous and greatly compresses the space of signs.

We will now analyze the information resource tatjana.in.ua from the ECCS type B2C (Figure 5). In fig. 6-7 gives the result of finding the trend in a time series of smoothing methods for the information resource tatjana.in.ua without B2C.

In fig. 8-9 results of median filtration are presented. To construct graphs and histograms, the largest and smallest smoothing interval is selected, so that the dependence of the degree of data smoothing depending on the interval can be seen. In fig. 10-12 expositional smoothing is given.

In fig. 12-13 provides smoothing formulas from Kendel. In fig. 14 - dendrogram, and in fig. 15 is a correlation field.

We will now analyze the functioning of the information resource vgolos.com.ua as an example of the ECCS (Figure 16).

To construct curls (Fig. 17) a table is analyzed for the computation of the frequency of sorted data. On the basis of the correlation coefficients for each table with the values of the smoothed functions, the corresponding correlation matrices were constructed (Figures 18-20). From the provided data, a property object table is generated. Data was split by years (2011-2015). For a graphical representation, a dendrogram has been constructed that shows the formed clusters (Fig. 21).

This paper solves the problem of current scientific research and development of methods and means of information resources processing in ECCS. In the upshot used the classification, mathematical and software architecture and overall ECCS. In the paper the terminology and electronic content commerce systems are analyzed and classified to determine their characteristic patterns, trends, process design and simulation. The authors developed a formal model ECCS for shortcomings determining of existing methods and means of resources processing. They developed also standardized methods for information resources processing in ECCS. The architecture of modules is implementing stages of commercial content lifecycle in ECCS is proposed. Software for information resources processing increased attendance of electronic content commerce systems is suggested. From the perspective of systemic approach is applying the principles of information resources processing in ECCS. This made it possible to develop methods for the commercial content formation, management and support. The proposed integrated method of content support makes it possible to develop a module of commercial content realization. In the present paper, the main regularities of ECCS classes and models opportunities are defined. The authors identified the transition from the information resources processing for their implementation. Formal models of the information resources formation, management and implementation are proposed. They allow realizing optimally the architecture of ECCS. The most significant factor taken into account in the formalization and algorithm models is the use of research tools for hardware and software IT.
