Question-Answering for Intelligent On-Line Help: The Process of Intelligent Responding

This article examines the process of specifying a question-answering help facility in the context of UNIX mail. The specification was based upon experimental expert-user facilitative dialogues. These dialogues were analyzed using a classification scheme developed for the purpose. The scheme provides a metalanguage for describing patterns of intent and rhetorical structure in dialogue. Using the scheme as a tool, common patterns in expert-user dialogue emerged, providing insights into both tutoring strategy and the linguistic forms required to generate help output. These were refined to form a set of frames consisting of stereotypical patterns of rhetorical predicates to answer different types of questions which could be adapted to the needs of a particular user. The significance of the system developed from this specification is discussed.     

Interreligious dialogue groups and the mass media

ABSTRACT

Interreligious dialogues have received attention since they were introduced as a security policy and social pacification measure after the attack on 9/11. This essay examines the development of interreligious dialogue in Germany as well as the influence of media discourses on interreligious dialogue and asks to what extent they affect the motives, goals and modes of communication of both Muslim and non-Muslim participants. This analysis leads to the thesis that the mass media’s frequent security-policy framing of Islam within issues of integration, violence, and threat has developed interreligious dialogue groups as a space of face-to-face coping processes with the imagined religious conflict. Muslims attend it in order to put Islam in a different and positive frame. For the Christian participants this also presents the opportunity to reach a new relevance of religion in the public secular space.     

The space between us: considering online media for interreligious dialogue

ABSTRACT

The internet has been conceptualized as a public sphere in which constructive dialogues – such as inter-religious dialogues – can occur. Public spheres, however, require reason, reflectivity and sincerity rarely found in most web spaces. Therefore, this approach might be counterproductive. Instead, I suggest we consider online communication as a Foucauldian discourse, a site of struggle, in which norms and concepts are negotiated. This chapter considers a few theoretical frameworks that allow researchers to critically survey online inter-religious dialogue. Four case studies are then reviewed in light of these theoretical considerations. The chapter argues that online discourses need to be examined by paying attention to the technological affordances, the social and cultural context, and the linguistic strategies employed. It is suggested that, for interreligious dialogue to happen, it needs to carve out a space within this online media that is dedicated to contemplation and openness.     

Formal systems of dialogue rules

Section 1 contains a survey of options in constructing a formal system of dialogue rules. The distinction between material and formal systems is discussed (section 1.1). It is stressed that the material systems are, in several senses, formal as well. In section 1.2 variants as to language form (choices of logical constants and logical rules) are pointed out. Section 1.3 is concerned with options as to initial positions and the permissibility of attacks on elementary statements. The problem of ending a dialogue, and of infinite dialogues, is treated in section 1.4. Other options, e.g., as to the number of attacks allowed with respect to each statement, are listed in section 1.5. Section 1.6 explains the concept of a chain of arguments.From section 2 onward four types of dialectic systems are picked out for closer study: D, E, Di and Ei. After a preliminary section on dialogue sequents and winning strategies, the equivalence of derivability in intuitionistic logic and the existence of a winning strategy (for the Proponent) on the strength of Ei is shown by simple inductive proofs.Section 3 contains a — relatively quick — proof of the equivalence of the four systems. It follows that each of them yields intuitionistic logic.     

Collaborative dialogue patterns in naturalistic one-to-one tutoring

Naturalistic one-to-one tutoring is more effective than traditional classroom teaching methods, but there have been few attempts to examine the features of normal tutoring that might explain its advantage. This project explored dialogue patterns in two samples of naturalistic tutoring with normal unskilled tutors (as opposed to expert tutors): graduate students tutoring undergraduates in research methods and high school students tutoring 7th graders in algebra. We analysed the extent to which those tutoring protocols manifested components that have been emphasized in contemporary pedagogical theories and intelligent tutoring systems: active student learning, sophisticated pedagogical strategies, specific examples and cases, collaborative problem solving and question answering, deep explanatory reasoning, convergance toward shared meanings, feedback, error diagnosis and remediation, and affect. The most prominent components consisted of collaborative problem solving, question answering, and explanation in the context of specific examples. We identify frequent dialogue patterns that characterize these collaborative processes.

The development and analysis of tutorial dialogues in AutoTutor Lite

The goal of intelligent tutoring systems (ITS) that interact in natural language is to emulate the benefits that a well-trained human tutor provides to students, by interpreting student answers and appropriately responding in order to encourage elaboration. BRCA Gist is an ITS developed using AutoTutor Lite, a Web-based version of AutoTutor. Fuzzy-trace theory theoretically motivated the development of BRCA Gist, which engages people in tutorial dialogues to teach them about genetic breast cancer risk. We describe an empirical method to create tutorial dialogues and fine-tune the calibration of BRCA Gist’s semantic processing engine without a team of computer scientists. We created five interactive dialogues centered on pedagogic questions such as “What should someone do if she receives a positive result for genetic risk of breast cancer?” This method involved an iterative refinement process of repeated testing with different texts and successively making adjustments to the tutor’s expectations and settings in order to improve performance. The goal of this method was to enable BRCA Gist to interpret and respond to answers in a manner that best facilitated learning. We developed a method to analyze the efficacy of the tutor’s dialogues. We found that BRCA Gist’s assessment of participants’ answers was highly correlated with the quality of the answers found by trained human judges using a reliable rubric. The dialogue quality between users and BRCA Gist predicted performance on a breast cancer risk knowledge test completed after exposure to the tutor. The appropriateness of BRCA Gist’s feedback also predicted the quality of answers and breast cancer risk knowledge test scores.     

When Are Tutorial Dialogues More Effective Than Reading?

It is often assumed that engaging in a one-on-one dialogue with a tutor is more effective than listening to a lecture or reading a text. Although earlier experiments have not always supported this hypothesis, this may be due in part to allowing the tutors to cover different content than the noninteractive instruction. In 7 experiments, we tested the interaction hypothesis under the constraint that (a) all students covered the same content during instruction, (b) the task domain was qualitative physics, (c) the instruction was in natural language as opposed to mathematical or other formal languages, and (d) the instruction conformed with a widely observed pattern in human tutoring: Graesser, Person, and Magliano's 5-step frame. In the experiments, we compared 2 kinds of human tutoring (spoken and computer mediated) with 2 kinds of natural-language-based computer tutoring (Why2-Atlas and Why2-AutoTutor) and 3 control conditions that involved studying texts. The results depended on whether the students' preparation matched the content of the instruction. When novices (students who had not taken college physics) studied content that was written for intermediates (students who had taken college physics), then tutorial dialogue was reliably more beneficial than less interactive instruction, with large effect sizes. When novices studied material written for novices or intermediates studied material written for intermediates, then tutorial dialogue was not reliably more effective than the text-based control conditions.     

Story Problems: Where Do the Agonists of the Dialogue Model of Argument Interact?

When discussing dialogue, argumentation researchers rarely draw the distinction between the story world and interactional world. While mediators often help to shape the interactions among agonists in the emerging flow of spoken discourse, writers of postulated dialogues narrate them, constructing a story world that depicts the agonists, depicts their utterances and their circumstances. In this paper, I ask where the agonists of the dialogue model of argument interact, and I show that they often interact in the story world of postulated dialogues. Postulated dialogues are story problem conversations. Common in textbooks, exams, and standardized tests, story problems create hypothetical situations to illustrate formal relationships among variables, and are designed to be read in a theoretical attitude that treats the characters, objects, and circumstances that they depict as given. When argumentation researchers examine postulated dialogues, they tend to adopt a theoretical attitude, limiting their analysis to the conversation between the agonists depicted in the story world. Reading this way makes it easier to overlook the interactional world where the writing and reading of the texts takes place, obscuring the fact that they are narrated dialogues, often written by researchers. Reading this way also makes it easier to confirm the traditional participation framework of the dialogue model of argument.     

Dialectic Dialogue: A new method for inter-religious dialogue

Presented in this article is a new method for dialogue between faith traditions. The proposed new method is presented in the form of a theoretical dialogue between Jews and Christians concerning 'salvation'. It is set forth as a 'dialectic dialogue' that shifts the focus from a direct comparison of the traditions to an indirect one. The indirect elements used are three dichotomies experienced by all and how the two traditions' adherents are encouraged to understand them is the object of discussion. This dialogue, which compares how the two traditions teach their adherents to frame these dichotomies, avoids the problems that often bring inter-religious dialogues to a premature end.     

A dialogue system specification for explanation

This paper builds a dialectical system of explanation with speech act rules that define the kinds of moves allowed, like requesting and offering an explanation. Pre and post-condition rules for the speech acts determine when a particular speech act can be put forward as a move in the dialogue, and what type of move or moves must follow it. A successful explanation has been achieved when there has been a transfer of understanding from the party giving the explanation to the party asking for it. The dialogue has an opening stage, an explanation stage and a closing stage. Whether a transfer of understanding has taken place is tested by a dialectical shift to an examination dialogue.     

The ecclesial dimension in the dialogue between theology and science

This article discusses the role of the science–religion dialogue in reaction to modern secularism, atheism and nihilism. It is argued that the only viable way for such a dialogue is along the lines of radical theological commitment implying the ecclesial dimension. It is carefully discussed as to how the ecclesial dimension can enter the dialogue. Ultimately it is concluded that the dialogue between science and theology explicates the para-eucharistic essence of science, thus reconciling it with theology in the sense of the commonality of their experiential origin in humanity made in the image of God.     

The vocal dialogue in 9/11 pregnant widows and their infants: Specificities of co-regulation

Mothers who were pregnant and widowed on September 11, 2001, and their 4–6-month infants (in utero on 9/11) were filmed during face-to-face interaction and their vocal dialogues were examined via microanalysis. Mothers were White, well-educated, mean age 34.3 years, and far from the World Trade Center site on 9/11; infants were 4–6 months, half female. We examined the bi-directional, moment-by-moment co-regulation of the timing of vocal dialogue, and particularly turn taking, in mother-infant and stranger-infant interactions, with time-series models. We analyzed the contingent coordination of durations of (1) vocalizations of the turn-holder, and (2) switching-pauses at the moment of the turn exchange. The switching pause is an aspect of the rhythm of the turn-holder who, after taking a turn, yields the floor to the partner through the switching pause. Turn taking is the lynchpin of dialogue, and the bi-directional contingent coordination of the switching-pause regulates the turn exchange. Both partners showed signs of risk and resilience. The 9/11 mothers did not coordinate the timing of turn taking with their infants, a highly unusual finding. In contrast, the 9/11 infants did coordinate the timing of turn taking with their mothers, and with the “stranger,” forms of resilience. We propose that the 9/11 mother’s difficulty coordinating with the infant’s turn taking rhythm is a mode of transmission of her trauma to the infant. This work expands our knowledge of the specificities of co-regulation in the context of the 9/11 trauma.     

Dialogue Foundations: Dialogue Logic Revisited: Erik C. W. Krabbe

In an attempt to redeem the Lorenzen-type dialogues from their detractors, it is perhaps best first to provide a survey of the various benefits these dialogues have been supposed to yield. This will be done in Section I. It will not be possible, within the confines of this paper, to scrutinize them all, but in Section II we shall delve deeper into the capacity of this type of dialogue to yield a model for the immanent criticism of philosophical positions. Section III will extend the concept of a dialogue in such a way as to conform better with our intuitive conceptions of what a rational discussion of a position should contain. This will be followed up by a concept of 'winning a dialogue' that takes position midway between the old conception of 'winning one play' and that of the full-fledged presentation of a winning strategy (a proof). Concepts of 'rational discussion' are thus shown to be, plausibly, more fundamental than those of proof. In Section IV, I shall discuss the specific problems about dialogical foundations put forward by Wilfrid Hodges.     

Two traditions,one space: orthodox Christians and Muslims in dialogue

The Eastern Orthodox Church has encountered Islam from the first decades of its appearance and they interacted in a variety of ways. Most frequently the meeting took the form of polemical clash and confrontation. However, in the many centuries of silent coexistence, it was often expressed in a concrete form of dialogue that sought to define the differences and the positions of the two religious forms and experiences. The present study focuses on the contemporary academic dialogues between Orthodox Christianity and Islam which began in the spring of 1985 at Holy Cross Greek Orthodox School of Theology in Brookline, MA. These dialogues were initiated by the Ecumenical Patriarchate of Constantinople and further meetings were held under its auspices in Chambésy, Constantinople (Istanbul), Athens, and Amman. This article presents the issues discussed, pointing to the fact that peaceful coexistence and justice may only prevail on a basis of mutual knowledge and understanding of the other.     

Toward a mechanistic psychology of dialogue

Traditional mechanistic accounts of language processing derive almost entirely from the study of monologue. Yet, the most natural and basic form of language use is dialogue. As a result, these accounts may only offer limited theories of the mechanisms that underlie language processing in general. We propose a mechanistic account of dialogue, the interactive alignment account, and use it to derive a number of predictions about basic language processes. The account assumes that, in dialogue, the linguistic representations employed by the interlocutors become aligned at many levels, as a result of a largely automatic process. This process greatly simplifies production and comprehension in dialogue. After considering the evidence for the interactive alignment model, we concentrate on three aspects of processing that follow from it. It makes use of a simple interactive inference mechanism, enables the development of local dialogue routines that greatly simplify language processing, and explains the origins of self-monitoring in production. We consider the need for a grammatical framework that is designed to deal with language in dialogue rather than monologue, and discuss a range of implications of the account.     

Dialogue games: Conventions of human interaction

Natural dialogue does not proceed haphazardly; it has an easily recognized episodic structure and coherence which conform to a well developed set of conventions. This paper represents these conventions formally in terms related to speech act theory and to a theory of action.The major formal unit, the dialogue game, specifies aspects of the communication of both participants in a dialogue. We define the formal notion of dialogue games, and describe some of the important games of English. Dialogue games are conventions of interactive goal pursuit. Using them, each participant pursues his own goals in a way which sometimes serves the goals of the other. The idea of dialogue games can thus be seen as a part of a broader theoretical perspective which characterizes virtually all communication as goal pursuit activity.We also define and exemplify the property of Motivational Coherence of dialogues. Motivational Coherence can be used as an interpretive principle in explaining language comprehension.Actual dialogue games have a kind of causal connectedness which is not a consequence of their formal properties. This is explained in terms of a theory of action, which is also seen to explain a similar attribute of speech acts.
