A method of forming a mandatory set of metadata for retro collections of a digital mathematical library is presented. The open resources of the Semantic Network were used as a source for completing metadata. With the help of the software tools of the metadata factory of the digital mathematical library Lobachevskii-DML, the main processes of text analysis of documents of digital retro collections are performed, in particular, the selection of named entities. Further, through the system of queries in the semantic network, the search and selection of information objects is carried out. After performing automatic filtering and normalization, the obtained information is included in the metadata set. As one of the results, the process of forming a mandatory set of metadata for one of the collections of the digital library Lobachevskii-DML – a retro-collection of articles of the journal "Izvestia of the Physics and Mathematics Society at Kazan University" is presented.

The industrial application of lipolytic enzymes has been studied mainly due to the ability of these enzymes in catalyze reactions of synthesis and their stability in various organic solvents. One possibility is the use of lipase the organic synthesis, taking advantage as the generation of waste and difficult recovery of sub bioproducts. In this work, we carried out a selection of eighty-four isolates of Bacillus amazonian for lipase production, of which 30 strains showed lipolytic activity. The study of the culture conditions was performed through a Plackett-Burman experimental design using the strain that presented the highest lipolytic activity in a culture medium using glycerol as substrate.  The studied conditions were: concentration of soybean oil, olive oil, triton X-100, gum arabic, glycerol, and (NH4)2SO4, pH, temperature and concentration of inoculums. The best result obtained were 27 U/L in 48 h of cultivation by Bacillus circulans BL53. This work shows that the search and selection of microorganism with lipolytic activities can facilitate the discovery of new lipases, with potential use as by-product surplus.

Fundamental Requirement

Evolution is a fundamental requirement for useful ontologies. Knowledge evolves continuously in all fields of knowledge due to the progress in research and applications. Because they are theories of knowledge in a precise domain, Ontologies need to evolve because the domain has changed, the viewpoint of the domain has changed or because problems in the original domain conceptualization have to be resolved or have been resolved (Noy & Klein, 2003). Moreover, in open and dynamic environments such as the Semantic Web, the ontologies need to evolve because domain knowledge evolves continually (Heflin & Hendler, 2000) or because ontology-oriented software-agents must respond to changes in users’ needs (Stojanovic, Maedche, Stojanovic, & Studer, 2003).

The emergence of the World Wide Web made available massive amounts of data. This data, created and disseminated from many different sources, is prepared and linked in a way that is well-suited for display purposes, but automation, integration, interoperability or context-oriented search can hardly be implemented. Hence, the Semantic Web aims at promoting global information integration and semantic interoperability, through the use of metadata, ontologies and inference mechanisms. This chapter presents a Semantic Model for Tourism (SeMoT), designed for building Semantic Web enabled applications for the planning and management of touristic itineraries, taking into account the new requirements of more demanding and culturally evolved tourists. It includes an introduction to relevant tourism concepts, an overview of current trends in Web Semantics research and a presentation of the architecture, main features and a selection of representative ontologies that compose the SeMoT.

This chapter introduces the emerging technology of Semantic Web services. It concentrates on two dominant specifications in this domain, namely OWL-S (Web ontology language for services) and WSMO (Web services modeling ontology). We briefly introduce Web services and Semantic Web, two main technologies underlying the Semantic Web services technology and then explain most of the key features of this technology together with simplified examples. We discuss three aspects of Semantic Web services: specifications for semantic descriptions of services, intelligent discovery and selection of services using semantic descriptions, and finally, building more complex services by composing existing ones. Our main goal in this chapter is not only to present an abstract view of this technology but also the introduction of the technical details of the two existing specifications.

AbstractIn the recent years, awareness has risen by an increasing number of researchers that we need studies that appropriately model the complexity of school improvement if we want to increase our knowledge about school improvement substantially and to close the identified research gaps within this field (Feldhoff T, Radisch F, Klieme E, J Educ Admin 52(5):565–736, 2014; Hallinger P, Heck RH, School Effect School Improv 22(2):149–173, 2011; Sammons P, Davis S, Day C, Gu Q, J Educ Admin 52(5):565–589, 2014). So far, respective quantitative studies, that appropriately consider those complexities, have hardly been realized because of the high efforts of current methods and costs involved (Feldhoff T, Radisch F, Bischof LM, J Educ Admin 2(54):209–240, 2016). It is, therefore, apparent to look for new, innovative methods that can adequately take into account the complexity of school improvement. For a reasonable search and selection of innovative methods, it is necessary to describe the systematic complexity of school improvement and the resulting requirements for the methods in more detail. This is a central goal in this chapter. For this reason, we present our framework of complexity. We then formulate questions that will prompt the reader to reflect critically upon the methods in general and especially in this volume.
