At the preparation and application stages, values of all unique coefficients that are necessary for formulating the research results were estimated. Thus, prior to the Monitoring final stage, the following values have to be estimated:

- Social significance coefficient (SSc) for each parameter.

- Criteria relevance coefficient (CRc) for each criteria of each parameter.

- Parameter relevance coefficient (PRc) for each parameter for each official website.

- Parameter availability coefficients (K_{1}) for each parameter (where PRc value = 1) for each official website.

- Comprehensiveness coefficients (K_{2}) for each comprehensiveness criterion (where CRc value = 1) of each parameter (where PRc value = 1) for each official website.

- Relevance coefficients (K_{3}) for each relevance criterion (where CRc value = 1) of each parameter (where PRc value = 1) for each official website.

- Navigability coefficients (K_{4}) for each navigability criterion (where CRc value = 1) of each parameter (where PRc value = 1) for each official website.

- HTML accessibility coefficients (K_{5}) for each HTML accessibility criterion (where CRc value = 1) of each parameter (where PRc value = 1) for each official website.

- File accessibility coefficients (K_{6}) for each file accessibility criterion (where CRc value = 1) of each parameter (where PRc value = 1) for each official website.

- Graphic accessibility coefficients (K_{7}) for each graphic accessibility criterion (where CRc value = 1) of each parameter (where PRc value = 1) for each official website.

Assessing an official website is made basing on the aggregate value of separate parameters and criteria by applying the information accessibility coefficient (IACoef). This coefficient is calculated by the following formula:

Where:

i – parameter ordinal number (from 1 to n);

j – criterion ordinal number (from 1 to 7);

K_{ij} – Coefficient for the j^{th} criterion, the i^{th} parameter

CRc_{ij} – Criterion Relevance Coefficient for the j^{th} criterion, the i^{th} parameter;

PRc_{i} – Parameter Relevance Coefficient for the i^{th} parameter;

SSc_{i} – Social Significance Coefficient for the i^{th} parameter

In the shown formula each criterion used in evaluating the parameter is used as a “fine” diminishing the value of the information accessibility coefficient for the particular parameter and for the whole website. The size of the “fine” will vary depending on the criterion importance.

The Availability criterion is the most important one since the negative evaluation of this parameter shall nullify its information accessibility.

The Comprehensiveness criterion is also among the principal ones reflecting quantitative characteristics of the information published at the official website. This accounts for the considerable value of the corresponding “fine”: 50% or 80% that can be charged for insufficient information volume.

The “fine” for insufficient HTML accessibility of the official website data is also considerable: it amounts to 80%. The reason for this is that in this case the information becomes virtually unavailable for searching with the traditional Internet search engines (Google, Yandex etc.), preventing users from finding and using this data.

Relevance of the information is less important than comprehensiveness and HTML accessibility. Thus, the “fine” for insufficient relevance is smaller: 15% or 30%, whereas the “fine” for insufficient file accessibility is just 15%.

Navigability and graphic accessibility criteria are the least important ones. Consequently, the “fines” for faults in these criteria are minimal: 5% and 10%, for navigability, and 5% for graphic accessibility.

The **IACoef** value may range from 0% (which normally means that the no website exists at all), to 100% meaning that the official website fully meets all the requirements. For obvious reasons, the latter does not happen in practice.
