Structured Approaches for Exploring Interpersonal Relationships in Natural Language Text

Human relationships have long been studied by scientists from domains like sociology, psychology, literature, etc. for understanding people's desires, goals, actions and expected behaviors. In this dissertation we study inter-personal relationships as expressed in natural language text. Modeling inter-personal relationships from text finds application in general natural language understanding, as well as real-world domains such as social networks, discussion forums, intelligent virtual agents, etc. We propose that the study of relationships should incorporate not only linguistic cues in text, but also the contexts in which these cues appear. Our investigations, backed by empirical evaluation, support this thesis, and demonstrate that the task benefits from using structured models that incorporate both types of information. We present such structured models to address the task of modeling the nature of relationships between any two given characters from a narrative. To begin with, we assume that relationships are of two types: cooperative and non-cooperative. We first describe an approach to jointly infer relationships between all characters in the narrative, and demonstrate how the task of characterizing the relationship between two characters can benefit from including information about their relationships with other characters in the narrative. We next formulate the relationship-modeling problem as a sequence prediction task to acknowledge the evolving nature of human relationships, and demonstrate the need to model the history of a relationship in predicting its evolution. Thereafter, we present a data-driven method to automatically discover various types of relationships such as familial, romantic, hostile, etc. Like before, we address the task of modeling evolving relationships but don't restrict ourselves to two types of relationships. We also demonstrate the need to incorporate not only local historical but also global context while solving this problem. Lastly, we demonstrate a practical application of modeling inter-personal relationships in the domain of online educational discussion forums. Such forums offer opportunities for its users to interact and form deeper relationships. With this view, we address the task of identifying initiation of such deeper relationships between a student and the instructor. Specifically, we analyze contents of the forums to automatically suggest threads to the instructors that require their intervention. By highlighting scenarios that need direct instructor-student interactions, we alleviate the need for the instructor to manually peruse all threads of the forum and also assist students who have limited avenues for communicating with instructors. We do this by incorporating the discourse structure of the thread through latent variables that abstractly represent contents of individual posts and model the flow of information in the thread. Such latent structured models that incorporate the linguistic cues without losing their context can be helpful in other related natural language understanding tasks as well. We demonstrate this by using the model for a very different task: identifying if a stated desire has been fulfilled by the end of a story

Generic and rhetorical structures of texts : two sides of the same coin?

Two major approaches to textual macro-structures have been developed during the last decades: Register & Genre Theory (R&GT) and Rhetorical Structure Theory (RST). Both stress that textual structures co-occur with contextual relations involving social action and subject matter, role structure and symbolic organization. The approaches, however, significantly differ in their conceptions of textual organization. Whereas R&GT conceives of texts as goal-oriented staged (i.e. linearly progressing, while still allowing for prosodic and recursive realizations of stages) interactions, RST conceptualises them as hierarchically structured entities in which certain elements are foregrounded (nuclei) and others are backgrounded (satellites); Based on empirical analyses of Viennese university students' essays, we will discuss in what ways generic and rhetorical organizations of texts relate to each other and what advances a combination of these two approaches may offer for text analysis and text linguistics. Through such a combinatory approach to analyzing texts, it becomes possible to identify systematic patterns of textual features in context (using R&GT) and culturally influenced, semantic coherence relations (using RST). Central to our discussion are issues involving the relation between hierarchical versus linear perspectives on text organization and the relation between cohesion and coherence

Peer mediation for conflict management: a Singaporean case study

The burgeoning interest in conflict and its management has recently begun to impact on schools and school systems worldwide. Motivated by a concern for increasing levels of violence in schools and student�student conflict, many school administrators are looking at conflict management programs as a means of dealing with the problem. Most of the more widely used programs have their origins in the United States; their appropriateness and effectiveness in other countries and cultures is, at best, unknown, and in some respects open to conjecture. In this paper the cultural appropriateness of a peer mediation program in a primary school in Singapore is the subject of investigation. The study also addresses, in an exploratory manner, the effectiveness of peer mediation as a mechanism for student�student conflict management

Agency in Social Context

Many political philosophers argue that interference threatens a person’s agency. And they cast political freedom in opposition to interpersonal threats to agency, as non-interference. I argue that this approach relies on an inapt model of agency, crucial aspects of which emerge from our relationships with other people. Such relationships involve complex patterns of vulnerability and subjection, essential to our constitution as particular kinds of agents: as owners of property, as members of families, and as participants in a market for labor. We should construct a conception of freedom that targets the structures of our interpersonal relations, and the kinds of agents these relations make us. Such a conception respects the interpersonal foundations of human agency. It also allows us to draw morally significant connections between diverse species of unfreedom—between, for instance, localized domination and structural oppression

Employing culturally responsive pedagogy to foster literacy learning in schools

 In recent years it has become increasingly obvious that, to enable students in schools from an increasingly diverse range of cultural backgrounds to acquire literacy to a standard that will support them to achieve academically, it is important to adopt pedagogy that is responsive to, and respectful of, them as culturally situated. What largely has been omitted from the literature, however, is discussion of a relevant model of learning to underpin this approach. For this reason this paper adopts a socio-cultural lens (Vygotsky, 1978) through which to view such pedagogy and refers to a number of seminal texts to justify of its relevance. Use of this lens is seen as having a particular rationale. It forces a focus on the agency of the teacher as a mediator of learning who needs to acknowledge the learner’s cultural situatedness (Kozulin, 2003) if school literacy learning for all students is to be as successful as it might be. It also focuses attention on the predominant value systems and social practices that characterize the school settings in which students’ literacy learning is acquired. The paper discusses implications for policy and practice at whole-school, classroom and individual student levels of culturally-responsive pedagogy that is based on a socio-cultural model of learning. In doing so it draws on illustrations from the work of a number of researchers, including that of the author

Through a discourse analysis lens less darkly: illuminating how SME principals and support agency practitioners see marketing in SMEs

The purpose of this paper is to explain the social contructivist approach taken to uncovering clearer, deeper meaning through a recent qualitative, interpretive and subjective research study. This study examined the ways in which marketing is seen and conducted in SMEs by SME principals and support agency practitioners. The research was designed with a particular method of data analysis (Discourse Analysis) in mind which was applied to the SME marketing context. The findings of the study provided a contribution to the SME marketing debate where the research approach taken proved to be instrumental in providing a contribution to both theory and practice of marketing in SMEs and the education, training and development activities of support agencies. The subjective nature of this research yielded benefits that would not have been available through a positivist research approach. The approach taken has more practical application than some traditionalists might believe. This paper explains how further understanding of SME marketing resulted from the study and how further original insights can be gained by applying the tools utilised in studies in SME marketing and marketing in other contexts
