The purpose of this paper is to develop a novel feature selection approach for automatic text classification of large digital documents – e-books of online library system. The main idea mainly aims on automatically identifying the discourse features in order to improving the feature selection process rather than focussing on the size of the corpus.

The proposed framework intends to automatically identify the discourse segments within e-books and capture proper discourse subtopics that are cohesively expressed in discourse segments and treating these subtopics as informative and prominent features. The selected set of features is then used to train and perform the e-book classification task based on the support vector machine technique.

The evaluation of the proposed framework shows that identifying discourse segments and capturing subtopic features leads to better performance, in comparison with two conventional feature selection techniques: TFIDF and mutual information. It also demonstrates that discourse features play important roles among textual features, especially for large documents such as e-books.

Automatically extracted subtopic features cannot be directly entered into FS process but requires control of the threshold.

The proposed technique has demonstrated the promised application of using discourse analysis to enhance the classification of large digital documents – e-books as against to conventional techniques.

A new FS technique is proposed which can inspect the narrative structure of large documents and it is new to the text classification domain. The other contribution is that it inspires the consideration of discourse information in future text analysis, by providing more evidences through evaluation of the results. The proposed system can be integrated into other library management systems.

This paper attempts to contribute to an expanding body of literature that critically engages with both the theory and practice of market segmentation. Through the theoretical lens of liminality and its implicit elements, the notion of boundary creation inherent in age‐based market segmentation of the youth market is explored.

Using empirical data collected as part of a longitudinal study on liminal consumers, marketing's attempt at laying down parameters and constructing borders is presented as a strategic exacerbation of liminal zones already replete with tension and ambiguity.

It is concluded that theoretical consideration of this data highlights the fluidity and porous nature of such constructed boundaries, rendering attempts at creating discernable, knowable segments, potentially futile. Thus by critically viewing this segment, not just as a marketing demographic, but as a liminal zone, an alternative consideration of the theory and practice of age segmentation is presented.

The longitudinal study spanned a period from midway through the participants' final months of primary education and early stages of secondary education. Research that focused on their completion of a year in secondary education would perhaps have yielded further insights.

This research offers tangible insights into the social worlds of a burgeoning market segment, albeit a liminal one, offering actionable realities based on the inextricable intertwining of their consumption practices and lived experiences.

Rather than view children as socio‐cultural non‐descripts who are of interest to marketers purely for their ability to be located along a continuum of cognitive development, this research aims to understand and explore the specific intricasies of the tweens' mediation of their liminal world using consumption practices

Consumption practices emerged that highlighted the attempted resolution and mediation of such tensions while also pointing to the clear mutability and ambiguity of supposed borders between child, tween and teen segmented groups. Age‐segmentation, conceptualised by marketers as a strategic creation of borders so as to enhance product offerings little reflects the realities of how age is perceived, experienced and acted out by those categorised within the margins and parameters of targeted marketing. By viewing this segment, not just as a marketing demographic but as a liminal zone where liminars “elude or slip through the network of classifications that normally locate states and positions in cultural space”, an alternative consideration of the theory and practice of age‐segmentation is presented.

Current segmentation systems almost invariably focus on linear segmentation and can only divide text into linear sequences of segments. This suits cohesive text such as news feed but not coherent texts such as documents of a digital library which have hierarchical structures. To overcome the focus on linear segmentation in document segmentation and to realize the purpose of hierarchical segmentation for a digital library’s structured resources, this paper aimed to propose a new multi-granularity hierarchical topic-based segmentation system (MHTSS) to decide section breaks.

MHTSS adopts up-down segmentation strategy to divide a structured, digital library document into a document segmentation tree. Specifically, it works in a three-stage process, such as document parsing, coarse segmentation based on document access structures and fine-grained segmentation based on lexical cohesion.

This paper analyzed limitations of document segmentation methods for the structured, digital library resources. Authors found that the combination of document access structures and lexical cohesion techniques should complement each other and allow for a better segmentation of structured, digital library resources. Based on this finding, this paper proposed the MHTSS for the structured, digital library resources. To evaluate it, MHTSS was compared to the TT and C99 algorithms on real-world digital library corpora. Through comparison, it was found that the MHTSS achieves top overall performance.

With MHTSS, digital library users can get their relevant information directly in segments instead of receiving the whole document. This will improve retrieval performance as well as dramatically reduce information overload.

This paper proposed MHTSS for the structured, digital library resources, which combines the document access structures and lexical cohesion techniques to decide section breaks. With this system, end-users can access a document by sections through a document structure tree.

The purpose of this research is to identify the organization, functions, and forms of talk that occur as groups collectively review, interpret, and organise information sought and retrieved as part of a learning activity.

Participants in the study were undergraduate students conducting a series of group investigations into the topic of information management. A content analysis of the discourse generated during the presentation‐planning stage of the group investigations was conducted.

Findings relate to the discovery of a focus formulation step; speakers' use of structuring, informing, eliciting, and summarizing sequences; and speakers' use of exploratory, coordinating, disputational, and cumulative forms of talk. Variations in the use of the functions and forms of talk across the steps of the task and across the groups are discussed.

Issues relating to the reliability and validity of the content analysis are discussed; along with the implications of the study for the support of dialogic interaction during collaborative information seeking and use.

The originality of the paper rests in analyzing collaboration in information seeking and use as a discourse; and in hypothesizing as to the nature of educationally‐valued interaction when speakers collaborate on the seeking and use of information in learning settings.

Producing meeting documents requires an instantaneous recorder during meetings, which costs extra human resources and takes time to amend the file. However, a high-quality meeting document can enable users to recall the meeting content efficiently. The paper aims to discuss these issues.

An application based on this framework is developed to help the users find topics and obtain summarizations of meeting contents without extra effort. This app uses the Bluemix speech recognizer to obtain speech transcripts. It then combines latent Dirichlet allocation and a TextTiling algorithm with the speech script of meetings to detect boundaries between different topics and evaluate the topics in each segment. TextTeaser, an open API based on a feature-based approach, is then used to summarize the speech transcripts.

The results indicate that the summaries generated by the machine are 85 percent similar to the records written by humankind.

To reduce the human effort in generating meeting reports, this paper presents a framework to record and analyze meeting contents automatically by voice recognition, topic detection, and extractive summarization.

Suggests that the development of new interactive service is stimulating the global convergence of the telecommunications, computer and media markets, creating an integrated industry, but there is some doubt about customer demand and how to approach it. Presents a study which contributes to the discourse on segmentation with a view to targeting. Tests the hypothesis that there is a relationship between the early adoption of previous technological innovations introduced over the past 15‐20 years and the predisposition to use new interactive services. The results of a small scale survey did not lend full support to this hypothesis; associations were established only in a small number of pairs of innovations. There were, however, significant subsegments within the sample which were positively predisposed to using education services, travel, news/information and video‐on‐demand through the new interactive technologies. Within the evidence examined, it could not be established that early adopters of communications and computer products are necessarily a starting target market for emerging technologies. Concludes that exploitation of interactive services requires recognition of the likely existence of differentiated market segments and thus the crafting of focused marketing strategies for different service packages.

The purpose of this article is to illustrate through a case study how Bernstein's discussion of horizontal discourse can be used to inform processes of management development and organizational learning in multi‐functional organizations.

The approach taken is to reflect on a particular case of management development in which the author was instrumentally involved, using Bernstein's concepts of “repertoire”, “reservoir”, and the “circulation” and “exchange” of knowledge and strategies to further the understanding of the nature of learning and development interventions that aim to recognise, refine and disseminate tacit managerial knowledge.

The article discusses the background to internal management development interventions of this type, and briefly evaluates the outcomes of the case study against original objectives. Although much progress was made with an initial group of participants, in terms of realising and sharing tacit managerial knowledge and strategies, the organization did not take the second phase of the intervention forward.

The case study develops a conceptually informed approach to internal learning and development interventions that can inform future initiatives.

The discussion of this case is valuable in that it illustrates how concepts from the sociology of knowledge can be used to provide new insights into internal learning and development interventions that seek to make better use of the knowledge and practice of individual employees.

By stepping outside of the consumer socialization model (Ward, 1974) which for many years has resembled a ‘body of verified truths’ when it comes to understanding the complex intimacy between young consumers’ identities and the marketplace, this research aims to offer a theoretical and empirical reconsideration of the tangible light and shade, indeterminacy and yet ambition in which these young adolescents’ consumption practices and social contexts are inextricably intertwined.

Five different data collection methods were employed; namely personal diaries, in-depth interviews (which were conducted at two separate intervals), accompanied shopping trips, e-collages and researcher diaries. Each method was chosen so as to fulfil a specific purpose and reflect a specific angle of repose on the lived experience and consumption practices of a liminar – those at the heart of marketing’s newest strategic boundary.

This chapter describes some of the constituent elements of metaconsumption; the proposed theorization of the liminars’ consumption practices and a suggested diversion from ‘the effects’ perspective on young consumers’ socialization.

This chapter adds to those which problematize the tendency to view young consumers’ interactions with consumption as measurable by having to pass through pre-defined stages if they are to become recognized as complete consumers. Instead this research aligns with the perspective that young consumers, like adults, must mediate the shifting milieus of their social lives through engagement with a myriad consumption practices.

This perspective responds to an acknowledged empirical dearth (e.g. Martens, Southerton, & Scott, 2004). However, secondly in line with Arnould & Thompson’s (2005) original motivation that CCT encapsulate those who see our discipline as ripe with the potential for new theory generation and widespread applicability, this research aligns micro understandings and theorizations of children’s social worlds and consumer culture practices with existing meso- and macro-levels of consumption theory.

This paper aims to offer both a practical and reflective stance on a longitudinal multi-method interpretive consumer research project carried out with tween girls.

This multi-layered approach to data collection, involving qualitative diaries, accompanied shopping trips, e-collages and in-depth interviews, addresses the need, as articulated by Morrow and Richards (1996, p. 96) to “move away from the narrow focus of socialization and child development” toward a research approach that prioritizes children’s own experiences of their lives as children, thereby reconsidering the richness of children’s voices.

In line with those whose work seeks to privilege children’s knowledge of the world they inhabit while also emphasizing the need, as in the case of adult “doing” to place that existence within its broader social context (Russell and Tyler, 2005, p. 227), diaries, in-depth interviews, shopping trips, e-collages and researcher diaries were used to access the world of these social neophytes as they mediate their social worlds through the ever pervasive prism of consumer culture. The light and shade of their worlds cannot be captured by adult-oriented perspectives on research which assume that young consumers are incompetent, worthy of debate merely to ascertain levelness of agency or of interest merely to quantify degrees of participation in and comprehension of the semiotic markers of our consumer society.

Only female consumers were involved in this study which underlines the need to engage with both genders when it comes to researching young consumers.

This paper offers a tangible contribution to the movement of research toward understanding young consumers’ worlds through engagement with multi-layered discourses and representations.

This multi-layered, multi-method research project acknowledges the enthralling complexity of these young consumers’ social worlds, giving a richness and immediacy to their accounts of the compelling intimacy between young adolescent identity and the marketplace.
