    Abstract This chapter deals with the processes by which the European vernaculars gained prestige vis-à-vis Latin from the late Middle Ages onwards. It addresses the “idea” of a standard language and how this has been advanced by particular actors and institutions across Europe, focusing primarily on the period from the Renaissance to the eighteenth century. It also considers whether standard languages are now outmoded concepts and suggests that we are now in a period characterized by destandardization.

    The large number of Web pages on many Web sites has raised\ud navigational problems. Markov chains have recently been used to model user navigational behavior on the World Wide Web (WWW). In this paper, we propose a method for constructing a Markov model of a Web site based on past\ud visitor behavior. We use the Markov model to make link predictions that assist new users to navigate the Web site. An algorithm for transition probability\ud matrix compression has been used to cluster Web pages with similar transition behaviors and compress the transition matrix to an optimal size for efficient probability calculation in link prediction. A maximal forward path method is used to further improve the efficiency of link prediction. Link prediction has been implemented in an online system called ONE (Online Navigation Explorer) to assist users' navigation in the adaptive Web site.

    Recent scholarship has tended to focus on the perceived inadequacies of recording to represent live jazz performance. Nevertheless, recordings are dominant in the dissemination of jazz and as such demand our critical attention to understand the social potential of jazz in the twenty-first century. This chapter examines the ability of recordings to influence perceptions of jazz when evaluated in different ways: firstly, retrospectively, for example when writing jazz history; secondly, historically, within their original context (that is at the time at which they were first disseminated); and thirdly, in their present context, when they are encountered by new audiences. In this chapter, these three particular temporal perspectives of listeners are explored in relation to recordings chosen deliberately for their quantifiable status in the jazz canon: ‘Livery Stable Blues’ (1917) recorded by the Original Dixieland Jazz Band from New Orleans is widely cited as the first jazz recording; Miles Davis’s album Kind of Blue (1959) is understood as the best selling and most popular jazz recording of all time.

    This book chapter aims to explore the affordances and limitations of Mixed Methods Social Network Analysis (MMSNA) from an ethics perspective. In line with Ifenthaler and Schumacher (2016) we define ethics as “a system of fundamental principles and universal values of right conduct”. There may be substantial ethical considerations when conducting MMSNA research in comparison to more ’standard’ social science approaches: lack of anonymization; potential to identify non-respondents; and identification of “hidden” sub-groups. We will use one practical example to highlight potential ethical issues when conducting MMSNA research. We hope that by raising awareness of the potential ethical issues, researchers, practitioners, and the actual participants will become more mindful of the affordances and limitations of MMSNA research approaches.

    This paper describes GET (Graph Editor and Tools), a tool based on Sowa's conceptual structures, which can be used for generic knowledge acquisition and representation. The system enabled the acquisition of semantic information (restrictions) for a lexicon used by a semantic interpreter for Portuguese sentences featuring some deduction capabilities. GET also enables the graphical representation of conceptual relations by incorporating an X-Windows based editor.

    Since the advent of New Austrian Tunneling Method (NATM), shotcrete as a primary means of support in tunnels has been widely applied. It’s most important features are durability, speed of application and cost effectiveness. This paper introduces some tables that provide guidelines for the thickness of shotcrete required in some common situations of mine roadways. In order to devise such tables, two different arch sections, together with three different overburden types, were considered. Geotechnical parameters such as apparent cohesion and angle of internal friction of surrounding rocks were chosen, based on the five-category classification of Bieniawski. Two K0 factors (the ratio of horizontal stress to vertical stress) and an average rock density were utilized. Using numerical methods, 60 models were then devised in this way. By applying interaction diagrams of axial force and the bending moment for different thicknesses of shotcrete, appropriate shotcrete thickness for these models were calculated. The results of this research, as well as the methodology applied, can be used in mining roadway support design and all types of civil engineering tunnels.

    User evaluations of search engines are expensive and not easy to replicate. The problem is even more pronounced when assessing adaptive search systems, for example system-generated query modification suggestions that can be derived from past user interactions with a search engine. Automatically predicting the performance of different modification suggestion models before getting the users involved is therefore highly desirable. AutoEval is an evaluation methodology that assesses the quality of query modifications generated by a model using the query logs of past user interactions with the system. We present experimental results of applying this methodology to different adaptive algorithms which suggest that the predicted quality of different algorithms is in line with user assessments. This makes AutoEval a suitable evaluation framework for adaptive interactive search engines.

    Key feature of a context-aware application is the ability to adapt based on the change of context. Two approaches that are widely used in this regard are the context-action pair mapping where developers match an action to execute for a particular context change and the adaptive learning where a context-aware application refines its action over time based on the preceding action’s outcome. Both these approaches have limitation which makes them unsuitable in situations where a context-aware application has to deal with unknown context changes. In this paper we propose a framework where adaptation is carried out via concurrent multi-action evaluation of a dynamically created action space. This dynamic creation of the action space eliminates the need for relying on the developers to create context-action pairs and the concurrent multi-action evaluation reduces the adaptation time as opposed to the iterative approach used by adaptive learning techniques. Using our reference implementation of the framework we show how it could be used to dynamically determine the threshold price in an e-commerce system which uses the name-your-own-price (NYOP) strategy.
