“…In order to evaluate performance, – we carried out tests to measure the speed of executing SPARQL queries depending on the size of the static and dynamic models of the knowledge graph, using the Metaphactory platform [ 8 ]. The parameters of the models that were analyzed and test results are presented in Table 2 .…”

Dynamic network monitoring systems are typically designed to solve a predefined number of tasks, new requirements lead to expensive development efforts and sometimes even require changes in the system architecture. Knowledge graphs are powerful and flexible tools for information integration and supported by a set of standardized vocabularies and languages (the “Sematic Web” toolset). In this work, we discuss the application of knowledge graphs to develop and analyze an analytical computing infrastructure for a dynamic network monitoring system. As a typical dynamic network, a multiservice telecommunication network is considered. The presented system combines static models of a telecommunication network and dynamic monitoring data and makes it possible to obtain complex analytical reports using SPARQL queries over the knowledge graph. Those reports are of crucial importance to network stakeholders for improving the network services and performance. First, we analyze problems solved by traditional monitoring systems, and identify the classes of problems such systems cannot solve. Then we propose an analytical monitoring system architecture based on knowledge graphs to address these classes of problems. We present the system structure and detailed descriptions of the ontological and mathematical models of the resulting knowledge graph. In order to test the architecture discussed, we create an example task of the analytical monitoring system and analyze system performance depending on the size of the knowledge graph. The results of the analysis are presented using a number of SPARQL queries.

“…To solve the problem, the modularized framework that enables a knowledge graph platform to support arbitrary functionalities for each knowledge graph is necessary. Although some platforms [3,4,11,12] adopted the modularized frameworks, most of them can not reuse external or third-party services. Without the external tools, it is a burden for a developer to implement and develop existing works to the platforms.…”

“…Recently, various AI-related applications leverage KGs as the prior knowledge to search for the optimal solution or to encode the realworld knowledge. Furthermore, public organizations and private Figure 1: Architecture of UWKGM enterprises exploit KGs as the hub data to deal with the legacy data and heterogeneous data [4]. KGs, therefore, have been widely gained attention in many communities.…”

A knowledge graph becomes a central data hub in the enterprise and the research communities. Nevertheless, the development of knowledge graphs is challenging due to the insufficient functionalities of knowledge graph management platforms. In this paper, we develop a knowledge graph management platform (UWKGM). This platform enables users to integrate arbitrary functionalities as RESTful API services in order to facilitate the knowledge graph development process. In the demonstration, we highlight the main features of UWKGM and its use cases on knowledge graph management tasks.

“…Domain-centric means that the underlying knowledge graphs have been selected beforehand and the scope of the portal is limited to a specific domain. However, the availability of tools for building such custom applications on top of LD is limited [4].…”

This paper presents a new software framework, Sampo-UI, for developing user interfaces for semantic portals. The goal is to provide the end-user with multiple application perspectives to Linked Data knowledge graphs, and a two-step usage cycle based on faceted search combined with ready-to-use tooling for data analysis. For the software developer, the Sampo-UI framework makes it possible to create highly customizable, user-friendly, and responsive user interfaces using current state-of-the-art JavaScript libraries and data from SPARQL endpoints, while saving substantial coding effort. Sampo-UI is published on GitHub under the open MIT License and has been utilized in several internal and external projects. The framework has been used thus far in creating six published and five forth-coming portals, mostly related to the Cultural Heritage domain, that have had tens of thousands of end-users on the Web.
