In a future scenario where many devices can be controlled using the voice, easy and intuitive access and will be crucial for avoiding cognitive overload when faced with many different systems and interaction models. We propose a model for interaction with spoken language interfaces with heterogeneous tasks, based on the idea of using a family of life-like characters. The properties of these cha...

With the rapid growth of real application domains for NLP systems, there is a genuine demand for a general toolkit from which programmers with no linguistic knowledge can build specific NLP systems. Such a toolkit should provide an interface to accept sample sentences and convert them into semantic representations so as to allow programmers to map them to domain actions. In order to reduce the ...

Guided-based systems are an alternative to natural language systems regarding the query construction method. We present a new solution that bridges the gap between these two types of systems by providing a hybrid interface which combines a graphical query interface for query construction with the correspondent natural language expression automatically generated by the system.

Abstract. Natural language Interfaces (NLIs) have the ability to make Geographic Information Systems more accessible for interdisciplinary researchers or any inexperienced users. However, majority of research on NLIs GIS explored visualization spatial data retrieval. Research geo-analytical questions is still lacking. Google Blockly, an open-source JavaScript library, frequently used developing...

Web applications and services are increasingly important in a distributed internet filled with diverse cloud applications, each of which enable the completion narrowly defined tasks. Given explosion scale diversity such services, their composition integration for achieving complex user goals remains challenging task end-users requires lot development effort when specified by hand. We present de...

In this paper, we propose a trainable system that can automatically identify the command boundaries in a conversational natural language user interface. The proposed solution makes the conversational interface much more user friendly, and allows the user to speak naturally and continously in a hands-free manner. The main ingredient of the system is the maximum entropy identification model, whic...

A natural language interface for relational databases has been utilized at AT&T Bell Laboratories as the natural language component of the DARPA ATIS common task. This is a part of a larger project that consists of incorporating a natural language component into the Bell Laboratories Speech Recognizer. The commercially available system used in this project was developed by Natural Language Inco...
