چکیده

Automatic classification of dialogues between clients and a service center needs a preliminary dialogue parameterization. Such a parameterization is usually faced with essential difficulties when we deal with politeness, competence, satisfaction, and other similar characteristics of clients. In the paper, we show how to avoid these difficulties using empirical formulae based on lexical-grammatical properties of a text. Such formulae are trained on given set of examples, which are evaluated manually by an expert(s) and the best formula is selected by the Ivakhnenko Method of Model Self-Organization. We test the suggested methodology on the real set of dialogues from Barcelona railway directory inquiries for estimation of passenger's politeness.

Optimization of Dialog Strategies using Automatic Dialog Simulation and Statistical Dialog Management Techniques

In this paper, we present a technique for learning optimal dialog management strategies. An automatic dialog generation technique, including a simulation of the communication channel, has been developed to acquire the required data, train dialog models, and explore new dialog strategies in order to learn the optimal one. A set of quantitative and qualitative measures has been defined to evaluat...

Modelling Paralinguistic Conversational Interaction Towards social awareness in spoken human-machine dialogue

Parallel with the orthographic streams of words in conversation are multiple layered epiphenomena, short in duration and with a communicative purpose. These paralinguistic events regulate the interaction flow via gaze, gestures and intonation. This thesis focus on how to compute, model, discover and analyze prosody and it’s applications for spoken dialog systems. Specifically it addresses autom...

Dialog-Based User Models

The paper investigates several approaches to user modeling in natural-language dialog systems. First, reasons are pointed out why user modeling has become so important in the last few years, and definitions are proposed for the notions of 'user model' and 'user modeling component'. Then, techniques for constructing user models in the course of a dialog are presented and recent proposals for rep...

Does active learning help automatic dialog act tagging in meeting data?

Knowledge of Dialog Acts (DAs) is important for the automatic understanding and summarization of meetings. Current approaches rely on a lot of hand labeled data to train automatic taggers. One approach that has been successful in reducing the amount of training data in other areas of NLP is active learning. We ask if active learning with lexical cues can help for this task and this domain. To b...

Speaker adaptation of language models for automatic dialog act segmentation of meetings

Dialog act (DA) segmentation in meeting speech is important for meeting understanding. In this paper, we explore speaker adaptation of hidden event language models (LMs) for DA segmentation using the ICSI Meeting Corpus. Speaker adaptation is performed using a linear combination of the generic speakerindependent LM and an LM trained on only the data from individual speakers. We test the method ...
