Interpretation Methods and Ambiguity Management in Multimodal Systems
نویسنده
چکیده
Naturalness and flexibility of the dialogue between users and multimodal systems can produce more than one interpretation and consequently ambiguities. This chapter deals the problem to correctly recognize user input for enabling a natural interaction. In particular, it analyses approaches that have to cope with issues connected to the interpretation process, dividing them into recognition-based, decision-based, and hybrid multilevel fusion strategies, and providing descriptions of some example of these methods. Moreover, this chapter provides classifications of ambiguities classifying them at a more general level in recognition, segmentation, and target ambiguities, and dividing them in a more detailed way in lexical, syntactical, and pragmatic ambiguities. Considering these classifications, this chapter analyses how interpretation methods support the correct recognition of ambiguities. Finally, this chapter presents methods applied after the interpretation process and that integrate it for solving different class of ambiguities using the dialogue between the user and the system.

Animated Interface Agent Applying Atms-Based Multimodal Input Interpretation
Two requirements should be met in order to develop a practical multimodal interface system, i.e., (1) integration of delayed arrival of data, and (2) elimination of ambiguity in recognition results of each modality. This paper presents an e cient and generic methodology for interpretation of multimodal input to satisfy these requirements. The proposed methodology can integrate delayed-arrival d...
متن کاملMultimodal Pain Management Protocol Versus Patient Controlled Narcotic Analgesia for Postoperative Pain Control after Shoulder Arthroplasty
Background: Our institution’s traditional pain management strategy after shoulder arthroplasty has involved the utilization of postoperative patient-controlled narcotic analgesia. More recently, we have implemented a protocol (TLC) that utilizes a multimodal approach. The purpose of this study was to determine whether this change has improved pain control and decreased narcotic utilization. ...
متن کاملAn Approach for Managing Ambiguities in Multimodal Interaction
Multimodal systems support people with different needs and different features during the interaction process making it more easy and natural. However naturalness can usually produce ambiguous interpretation. This paper discusses ambiguities in multimodal interaction proposing in particular two different examples of ambiguities: a) multimodal ambiguities produced combining un-ambiguous modal inf...

Introduction: Sense of cohesion can affect nurses' personal and professional performance and it is important to identify the factors involved in it. The aim of this study was to investigate the mediating role of ambiguity tolerance in the relationship between emotion management and sense of cohesion in nurses in Tehran. Methods: The present study was a descriptive-correlational modeling of str...
متن کاملShifting contexts in invisible computing environments
Invisible computing systems are highly context-dependent. Consequently, the influence that language has on contextual interpretation cannot be ignored by such systems. Rather, once language and other forms of human action are perceived by a system, its interpretative processes will of necessity be context-dependent. As an example, we illustrate how people simply and naturally create new context...
