The paper describes the application of semantic technologies and knowledge management systems in the area of crisis management by the Polish public administration. A brief analysis of crisis management is presented. An architecture for a knowledge management system with interfaces that use a controlled natural language is proposed. The paper demonstrates the usefulness of semantic knowledge management and automated reasoning in the field of public administration.

This article is devoted to the consideration of the issue of possibilities for the application of the project approach as a tool of the anti-crisis management system of the enterprise. The essential aspects of anti-crisis management as a separate direction of management activity at the enterprise are considered. Within the framework of the work, the main problems of the formation of effective anti-crisis management systems among domestic enterprises have been identified, which are becoming increasingly important in the context of the instability of the external environment. The content of the project approach to the implementation of management is analyzed, which consists in ensuring the structuredness, consistency and efficiency of the process of implementing certain measures of an organizational or economic nature. The main levels are highlighted within which the project approach is advisable to use, namely the methodological level, the resource level and the organizational level. The possibilities of effective integration of the project approach into the system of anti-crisis management of the enterprise have been substantiated by comparing and detailed characteristics of the basic needs of anti-crisis management, arising from the existing problems of its implementation, together with the key properties inherent in the project approach. The main groups of stakeholders interested in using the project approach in anti-crisis management of an enterprise have been identified, which include shareholders and owners, creditors, top management, personnel and consumers of the enterprise's products. The key features of the project approach in the system of anti-crisis management of an enterprise are characterized from the standpoint of potential positive impacts during its implementation in business practice, and potential constraints that can interfere with the relevant processes are analyzed. The sequence of implementation of the integration of the project approach into the system of anti-crisis management of the enterprise has been developed, includes six stages for the development, preparation, planning, implementation, control, assessment and adjustment of the corresponding process.

<div> <p>Non-destructive testing (NDT) data in civil engineering is regularly used for scientific analysis. However, there is no uniform representation of the data yet. An analysis of distributed data sets across different test objects is therefore too difficult in most cases.</p> <p>To overcome this, we present an approach for an integrated data management of distributed data sets based on Semantic Web technologies. The cornerstone of this approach is an ontology, a semantic knowledge representation of our domain. This NDT-CE ontology is later populated with the data sources. Using the properties and the relationships between concepts that the ontology contains, we make these data sets meaningful also for machines. Furthermore, the ontology can be used as a central interface for database access. Non-domain data sources can be integrated by linking them with the NDT ontology, making them directly available for generic use in terms of digitization. Based on an extensive literature research, we outline the possibilities that result for NDT in civil engineering, such as computer-aided sorting and analysis of measurement data, and the recognition and explanation of correlations.</p> <p>A common knowledge representation and data access allows the scientific exploitation of existing data sources with data-based methods (such as image recognition, measurement uncertainty calculations, factor analysis or material characterization) and simplifies bidirectional knowledge and data transfer between engineers and NDT specialists.</p> </div>

A cognitive model is a computational model of internal information processing mechanisms of the brain for the purposes of comprehension and prediction. CARINA metacognitive architecture runs cognitive models. However, CARINA does not currently have mechanisms to store and learn from cognitive models executed in the past. Semantic knowledge representation is a field of study which concentrates on using formal symbols to a collection of propositions, objects, object properties, and relations among objects. In CARINA Beliefs are a form of represent the semantic knowledge. The aim of this chapter is to formally describe a CARINA-based cognitive model through of denotational mathematics and to represent these models using a technique of semantic knowledge representation called beliefs. All the knowledge received by CARINA is stored in the semantic memory in the form of beliefs. Thus, a cognitive model represented through beliefs will be ready to be stored in semantic memory of the metacognitive architecture CARINA. Finally, an illustrative example is presented.

Terror attacks and natural disasters of the past decades have dramatically made governments, public health authorities, and communities aware of insufficiencies in crisis management practices. Information technology has the potential to advance these practices, but systems that support handling these courses of events still have low success rates. The authors set out to define a requirements engineering method suitable for the development of crisis management systems (CMS). The resulting method was formatively evaluated in a project aimed at defining functions for systems supporting international engagements in crisis situations. Each step in the method was documented by its objective, output, implementation, and the experiences gained from the case study. The most important features of the method are the Voice of the Customer Table for identification of user needs, Use Cases for determination of requirements from the needs, and scenarios and prototypes for validating the requirements with user representatives.
