This paper discusses the integration of an ontology with a natural language query engine to calculate and interpret epidemiological indicators for population health assessment. In this paper, we discuss the application of this approach to one type of possible query, which retrieves health determinants, causally associated with diabetes mellitus.

The most basic task of a natural language interface is to map the user's utterance onto some meaning representation which can then be used for further processing. The three biggest challenges which continue to stand in the way of accomplishing even this most basic task are extragrammaticality, ambiguity, and recognition errors. The system presented here, ROSE1: RObustness with Structural Evolut...

Natural language communication is very important in Human-Robot cooperative work. This paper presents an object sorting robotic system which is controlled by natural language commands. A PA-10 robot manipulator is issued commands like “pick the big red cube” to pick objects placed on a table. The robot learns to interpret the meaning of this type of natural commands by learning individual lexic...

The main objective of the INVOCA project is the development of a natural language interface to query the knowledge bases available on the Internet in the Linked Open Data. This project has been developed between the VOCALI enterprise and the TECNOMOD research group of the University of Murcia

The goal of this panel is to evaluate three natural language in terfaces which were introduced to the commercial market in 1985 (cf. Carnegie Group 1985, Kamins 1985, Texas Instru ments 1985) and to >'elate them to current research in corn putational linguistics. Each of the commercial systems selected as a starting point for the discussion (see Wahlsler 1986 for a functional comparision) was d...

This paper presents a method for interpreting metaphoric language in the context of a portable natural language interface. The method licenses metaphoric uses via coercions between incompatible ontological sorts. The machinery allows both previously-known and unexpected metaphoric uses to be correctly interpreted and evaluated with respect to the backend expert system.

We describe CARDIAC, a prototype for an intelligent conversational assistant that provides health monitoring for chronic heart failure patients. CARDIAC supports user initiative through its ability to understand natural language and connect it to intention recognition. The natural language interface allows patients to interact with CARDIAC without special training. The system is designed to und...

We consider the problem of building probabilistic models that jointly model short natural language utterances and source code snippets. The aim is to bring together recent work on statistical modelling of source code and work on bimodal models of images and natural language. The resulting models are useful for a variety of tasks that involve natural language and source code. We demonstrate thei...

This paper presents the method of domain knowledge extracting in NChiql, a Chinese natural language interface to databases. After describing the overall extracting strategy in NChiql, we mainly discuss the basic semantic information extracting method, called DSE. A semantic conceptual graph is employed to specify two types of modification and three types of verbal relationship among the entitie...

Surface realizers are used at the final phase of natural language text generation to convert abstract or symbolic representations of information to linguistic forms in a particular human language. Rules of grammar for the target language are applied to produce text that is syntactically, morphologically and orthographically correct. In this paper, we present the development of FilSuRe, a simple...
