Numerical information is often presented in graphs. However, this medium is problematic for certain audiences such as inexperienced graph readers, people with visual impairments and users of mobile technologies featuring small screens. We have developed a system called iGraph which provides short verbal descriptions with the information depicted in graphs and a way of interacting with it by mea...

In this paper we provide a first analysis of the research questions that arise when dealing with the problem of communicating pieces of formal argumentation through natural language interfaces. It is a generally held opinion that formal models of argumentation naturally capture human argument, and some preliminary studies have focused on justifying this view. Unfortunately, the results are not ...

Providing a natural language interface to ontologies will not only offer ordinary users the convenience of acquiring needed information from ontologies, but also expand the influence of ontologies and the semantic web consequently. This paper presents PANTO, a Portable nAtural laNguage inTerface to Ontologies, which accepts generic natural language queries and outputs SPARQL queries. Based on a...

Natural language has been the holy grail of query interface designers, but has generally been considered too hard to work with, except in limited specific circumstances. In this paper, we describe the architecture of an interactive natural language query interface for relational databases. Through a carefully limited interaction with the user, we are able to correctly interpret complex natural ...

A b s t r a c t . This report explains a natural-language interface to the formalism of XFST (Xerox Finite State Tool), which is a rich language used for specifying finite state automata and transducers. By using the interface, it is possible to give input to XFST in English and French, as well as to translate formal XFST code into these languages. It is also possible to edit XFST source files ...

Whereas many natural language researchers have identiied ways in which natural language systems need to be augmented in order to make current natural language interactions more natural, most evaluations of natural language interfaces have failed to study natural language in the context of its use. Since there are now restricted natural language systems available commercially, we feel that it is...

Natural language interfaces to databases are considered one of the best alternatives for final users who wish to make complex, uncommon and frequent queries, which is a very common need in organizations. The use of this type of interfaces has been very limited, due to their limited publicizing and the complexity to adapt them to users' needs, and because their precision varies widely. We propos...

Mobile devices both host and collect significant amount of data that could be interesting to users. To make this data easily accessible, it has to be stored in semantic repositories using a well-defined ontology. Relationships between data from various sources should be explicit. Natural language interface to such data is an attractive option for information access. However, there are semantic ...

In this paper, we introduce a natural language interface for human-robot interaction (HRI) to develop building guidance robots. We have developed POSTECH Spoken Dialog System for Guidance Robots (POSSDS-GR). POSSDS-GR consists of automatic speech recognizer, spoken language understanding, dialog manager, natural language generator, and text-to-speech synthesizer. Each module is designed and imp...
