Data mining projects are complex and have a high failure rate. In order to improve project management and success rates of such projects a life cycle is vital to the overall success of the project. This paper reports on a research project that was concerned with the life cycle development for large scale data mining projects. The paper provides a detailed view of the design and development of a generic data mining life cycle called DMLC. The life cycle aims to support all members of data mining project teams as well as IT managers and academic researchers and may improve project success rates and strategic decision support. An extensive analysis of eight existing life cycles leads to a list of advantages, disadvantages, and characteristics of the life cycles. This is extended and generates a conglomerate of several guidelines which serve as the foundation for the development of a new generic data mining life cycle. The new life cycle is further developed to incorporate process, people and data aspects. A detailed study of the human resources involved in a data mining project enhances the DMLC.

The present paper first and foremost aims to examine the sociolinguistic phenomenon of diglossia as it was depicted within the 19 and 20 century Greek linguistic community (1830-1976). More specifically, this study tries to explore the social context in general and the political-religious-ideological context in particular within which Modern Greek Diglossia (MGD for short) first presented and developed, and how it eventually declined. The paper at hand adopts a particular sociolinguistic analysis by providing the most suitable definition for the concept of diglossia – among the many variations that have been propounded with the passage of time – under which MGD could best be described and analysed. More concretely, the specific definition adopted in our case is the initial and original Fergusonian one. The term diglossia proposed by Ferguson refers to the social and functional differentiation of two linguistic varieties – namely an (H)igh and a (L)ow one – of the same language and of the same speech community for distinct purposes. Since Katharévousa (i.e., the H code) and Dhimotikí (i.e., the L code) in MGD constitute two varieties of the same language (i.e., the continuum of the Greek language) and of the same speech community, Ferguson’s model seems to be rather relevant and fairly applicable. Furthermore, due to the fact that diglossia almost always is interwoven within an historical as well as a social context, emphasis is placed on those two contexts. It has been stated by Mesthrie et al. (2000, p. 42) that ‘language is embedded in a social and historical context, and a full understanding of language can only be achieved by paying attention to those contexts’. Thus, both the historico-linguistic perspective and the socio-linguistic approach that are employed in this paper intend to explain the emergence, maintenance, attrition as well as demise of MGD in the light of external socio-politico-historical factors, on the one hand, and to carefully analyse the specific characteristics of the phenomenon of MGD as such, on the other. The raising of the national language query (i.e., which of the existing Greek varieties is going to become the standard, official, symbolic, written language of the Greek nation?) – is another parameter which has to be considered side by side with the modern Greek diglossic situation. In fact, the Language Question in Greece is transformed from a clearly linguistic issue into a sociopolitical issue. Above all, the very existence of MGD is regarded as embedded in the ideological beliefs of its speakers. As a result, the conflicts that took place between the proponents of Katharévousa and the representatives of Dhimotikí in common with the reasons for such conflicts are mentioned. In the case of MGD conflicts exist between the two diglossic varieties, when in other countries the diglossia situation is not problematic at all. In Greece H and L varieties compete because their supporters compete. Last but not least, the pr

In this article we examine the concepts of polysemy and homonymy. After a broad overview of the topic we focus on the treatment of several examples in dictionaries and indicate how listing problems can arise. We look at how polysemy and honomymy are dealt with in Chinese a language rich in ambiguous words full of connotations and associations and we look at some of the ensuing problems facing Chinese dictionary writers and suggest a user friendly model for ambiguous lexical entries. We explore how several English words such as the polysemous preposition 'over' can be dealt with in terms of image schemas and how this indicates a structured system in the mental lexicon. Vyvyan Evan's treatment of 'time' is also examined, his argument as to how it might be arranged in semantic memory and his conclusions about the lexicon having systematic semantic structure. We conclude by conceding that more work is required before the issues addressed in this paper can be unambiguously resolved.

Initilally beginning in Ireland, CoderDojo is a non-profit organisation that has grown rapidly into a global network of community based programming clubs. Mentors teach coding skills to young people aged between 7 and 17. All classes are free of charge and clubs operate entirely on a volunteer basis. The first Dublin 15 based CoderDojo began just over two years ago and continues to thrive during weekend sessions held at The Institute of Technology Blanchardstown (ITB), which offers the use of its premises and resources for the sessions. This paper will chronicle the involvement of ITB staff and students with the CoderDojo, Dublin 15 branch from its inception. How the various contributions of all parties lead to a highly successful collaboration that ultimately led to classes becoming self-sustainable as a local facility for Dublin 15 children. Furthermore, this collaboration not only yielded benefits for the young people encountering coding for the first time, but spotlighted the previously untapped skillset of computing students and staff to engage in civic outreach in the wider community.

This paper aims to give an account of a theory of a mental lexicon for German verbs of motion within the theory of Role and Reference Grammar [RRG] (cf. Van Valin 2005). The issue of how Aktionsarten in general and particularly verbs of motion, with their various alternations, are structured and how they are stored in an RRG-compatible lexicon is investigated. A time line model for RRG-Aktionsarten based on Reichenbach (1947) is developed to give a description of the structure of events assumed within RRG. Human knowledge is often represented in terms of inheritance networks. In this paper I use a model of inheritance networks to modify the present version of the lexicon in RRG. I will argue that we do not need basic Aktionsarten in the lexicon, if we analyze and decompose Aktionsarten and operators in terms of inheritance networks. I will show furthermore that we do not need multiple lexical entries for verbs like motion verbs that occur in a multitude of contexts with different Aktionsart readings (see example 2.1.1.a, b and 2.1.4), if we accept the idea of inheritance networks. Neither do we need a workshop module and lexical rules as suggested by Van Valin and LaPolla (1997) and Van Valin (2005).
本文的目的是在角色和指称语法理论[RRG] (cf. Van Valin 2005)中对德语运动动词的心理词汇理论进行解释。一般来说，动作动词，特别是动作动词，以及它们的各种变化，是如何被结构化的，以及它们如何被存储在一个与rrg兼容的词典中。在Reichenbach(1947)的基础上，建立了RRG- aktionsarten的时间线模型，以描述RRG内假设的事件结构。人类知识通常用遗传网络来表示。在本文中，我使用了一个继承网络模型来修改当前版本的RRG词典。如果我们从继承网络的角度分析和分解Aktionsarten和算子，我将论证我们不需要基本的Aktionsarten在词典中。我将进一步说明，我们不需要多个词汇条目来记录动词，比如出现在多种上下文中具有不同Aktionsart读数的动作动词(参见例2.1.1)。A, b和2.1.4)，如果我们接受继承网络的想法。我们也不需要Van Valin和LaPolla(1997)以及Van Valin(2005)建议的工作坊模块和词汇规则。

Mobile computing and communication devices are open to surreptitious privacy attacks using emotion detection techniques; largely utilising work carried out in the area of voice stress analysis (VSA). This paper extends some work in the area of removing emotion cues in the voice, specifically focusing on lie detection and presents the results of a pilot study indicating that the use of mobile phones in situations of stress is common and that awareness of VSA is low. Existing strategies for the removal or modification of emotion cues, based on models of synthesis are considered and weaknesses are identified.
