Lande D.V., Berezin B.A. and Pavlenko O.Yu. Algorithm for word segmentation based on the
shortest path algorithm inside a graph. Data Rec., Storage & Processing. 2017. Vol. 19. N 4. P. 3–15. —
Rus.
The features of word segmentation algorithms from such texts are considered. There are two main
models, namely, statistical one and the one using a dictionary. For models with a dictionary, a variant of
the maximal matching algorithm is noted for which there are modifications such as Forward Maximal
Matching (FMM) and Backward Maximal Matching (BMM) to be depending on the direction of text
processing. The second option for models with a dictionary is an algorithm that finds segmentation with a
minimum number of words. A new algorithm for words segmenting based on a modified wave algorithm
has been presented. The algorithm takes into account the features of the input data and is built in such a
way that the necessary calculations are performed in a single pass. This reduces its computational com-
plexity. A description of the word segmentation algorithm is given. An example is shown of splitting an
input string in English into words, representing it in the form of a graph and finding the shortest path.
To assess the quality of segmentation, the EDWS (Edit Distance of the Word Separator) method is
presented. A special tool was used to assess the segmentation of Chinese words with a test corpora based
on news texts. Evaluations of the quality of segmentation of words for the proposed algorithm (based on
the search for the shortest path) and a number of other known segmentators are obtained. An example of
segmentation of a news text in Russian is given. The possibilities of using the developed algorithm in the
problems of information search in national resources of the Internet are shown. The implementation of the
word segmentation algorithm is used when creating a generalized domain model based on monitoring of
the Chinese Internet segment resources.
The increase in the number of information resources of the Chinese Internet segment makes it nec-
essary to create of global information retrieval systems. For search indexes of such systems, fast, accurate
and complete segmentation of words from texts is necessary. The obtained estimates of segmentation
quality using the proposed algorithm for the formation of the search system index indicate the possibility
of its use for information resources of the Chinese Internet-segment. Tabl.: 3. Fig.: 5. Refs: 23 titles.
Key words: words segmentation, word segmentation quality, web resources monitoring, shortest
path search, wave algorithm.

networks. Data Rec., Storage & Processing. 2017. Vol. 19. N 4. P. 16–25. — Ukr.
The investigation deals with complex application of graph visualization and business analytics for
obtaining solutions of better quality, which is difficult to do utilizing traditional means, so graphs have
played a role in many of those solutions. The function of a graph is to represent links between things such
as a spatial network, revealing the organization structure. Relationships are fundamental for the spatial
network, which is one of the reasons of graph analysis and visualization having so much potential for
value. Nowadays, several of our most significant research and software development efforts are, in es-
sence, graph-based. The graph-based approaches gain deeper understanding of the dynamics of organiza-
tional and business processes.
The practice of optimization simulation of communication problems in spatial networks is faced
with the need to quickly obtain the corresponding image with the optimal plan. The use of computer-
rendered visualization for decision-making in business is a relatively recent phenomenon. Thus, the com-
position of available graph visualization software used by ordinary PCs is offered. Its usage allows ob-
taining weighted management decisions for dynamically changing values of data sets using the con-
structed graph on the results of optimization solutions. Fig.: 6. Refs: 11 titles.

An analysis of influence of rain drop down on the resolution power of marine radar by angular co-
ordinates, working in the millimeter and centimeter wavelength ranges has been performed. It is shown
that one of the directions of increase of safety of navigation using marine radar has the improvement of
their resolution in angular coordinates, since the atmospheric phenomenon on the path of the ship make a
significant error in the measurement of the angular coordinates by the radar surveillance navigation facili-
ties. The study of precipitation on the resolution power of marine radar by angular coordinates, antenna
which radiates a linear-polarized electromagnetic wave of millimeter and centimeter ranges has been pro-
vided. The interaction of the wave with particles of precipitation presented in the form of a power wave
from the effective surface of the scattering reflective volume of rain is taken into account. The effective
surface of scattering and attenuation on all particle sizes in the dropdown of rain on the way is found. It
was found that for the centimeter wavelength range ( = 3 cm...10 cm) attenuation is much higher than the
scattering. The resulting conditions to improve the resolution of the antenna of marine radar by angular
coordinates are in the centimeter wavelength range. In the millimeter range of wavelengths occurs as the
improvement of the resolution capability of the antenna of marine radar and its deterioration depending
on the intensity of precipitation. The deterioration of the resolution can reach 10 %. Refs: 11 titles.
Key words: angular coordinates, dispersion, absorption, radiation, function of dispersion, resolu-
tion, diagram of orientation of aerial, border of division, corporal corner, ship radar.

Kuznietsova N.V. Scoring card’s development for banking activities risks’ analysis. Data Rec.,
Storage & Processing. 2017. Vol. 19. N 4. P. 35–44. — Ukr.
The basic features of scoring card building such as a sequence of stages, roles and methodology of
development are considered. On example of the credit risks analysis it is shown how scoring card is built
and scoring points are calculated. It is also shown how by varying of the threshold to receive different rate
of good and bad credit applications which would be accepted. Also scorecard gives the possibility to de-
fine the size of risk by bad rate of credit application on each interval of the scorecard points. Moreover it
is recommended, in scoring cards, to take into account the risk’s profile that means to pay attention not
only on demographic characteristics of the applicants but also on their behaviour in the past. It is demon-
strated that the scoring cards are effective instrument in table view of scoring points for bank credit ana-
lytics. Using the scoring cards allows taking into account changes in the banking services market, operat-
ing with different cut-off thresholds and evaluating which degree of risk the bank takes on itself. Tabl.: 1.

An application of quantitative characteristics in the form of values of residual risk or probabilities
of overcoming by the violator of protection facilities of different security properties is offered for the
analysis of information security of the automated systems. To assess the protection of confidentiality of
telecommunications networks using appropriate information security systems, a mathematical model for
to determine the probability of overcoming the offender components of privacy is proposed. Tabl.: 1.

object-relational database Caché. Data Rec., Storage & Processing. 2017. Vol. 19. N 4. P. 56–63. — Ukr.
The classes and their relationships in hybrid, post-relational (object-relational) database manage-
ment system InterSystems Caché (InterSystems IRIS platform) are analyzed. A better notation to visual-
ize that class entities and relationships is proposed. The different approaches to visualize the Caché
classes and identify limitations of existing visualization tools are compared. Due to the fact that there are
76
many features in InterSystems Caché classes and relationships, a new notation development is required to
model the existing systems with all of their features displayed. Authors propose to extend UML notation
and compare it with existing UML solutions, which are not fully capable of visualizing all features under
Caché DBMS. This article also provides An information over a developed standard extension and a web-
based software which implements this standard is also provided. The features developed web-based solu-
tion for visualizing classes and their relationships, comparing it to existing visualization tools are de-
scribed. Fig.: 5. Refs: 6 titles

Boychenko A.V. and Lande D.V. Formation of management scenarios by means of investigation
of information space. Data Rec., Storage & Processing. 2017. Vol. 19. N 4. P. 64–70. — Ukr.
It is considered the development of a scenario approach and the construction of an information
technology, which allows in an automated mode, based on the analysis of the input documentation pack-
age, to solve the problem of the formation and ranking of scenarios of influencing the objects that corre-
spond to the selected key concepts.
A mathematical model of qualitative estimation of management activity scenarios for a subject
area is worked out. To construct a scenario, an abstract automaton is proposed that describes the require-
ments based on the description of the analytic task. The scenarios are singled out from the semantic net-
work. There are the vertices of concepts, and the arcs to be mutual relations, for example, «cause – con-
sequence». A modified ant colony optimization (ACO) approach for forming scenarios is proposed. To
check out the suggested technology, text domains were created for such subject areas as «Brexit», «Mass
Shuting», «Catalan referendum», «Saudi Arabian purge», «Zimbabwean coup d’etat», «Syrian civil war».
