In order to effectively access the rapidly increasing range of media content available in the home, new kinds of more natural interfaces are needed. In this paper, we explore the application of multimodal interface technologies to searching and browsing a database of movies. The resulting system allows users to access movies using speech, pen, remote control, and dynamic combinations of these modalities.
This demonstration presents the Annotation Librarian, an application programming interface that supports rapid development of natural language processing (NLP) projects built in Apache Unstructured Information Management Architecture (UIMA). The flexibility of UIMA to support all types of unstructured data – images, audio, and text – increases the complexity of some of the most common NLP development tasks.
For a natural language access to database system to be practical it must achieve a good match between the capabilities of the user and the requirements of the task. The user brings his own natural language and his own style of interaction to the system. The task brings the questions that must be answered and the database domaln+s semantics. All natural language access systems achieve some degree of success. But to make progress as a field, we need to be able to evaluate the degree of this success. For too long, the best we have menaged has been to...
We present Wikulu1 , a system focusing on supporting wiki users with their everyday tasks by means of an intelligent interface. Wikulu is implemented as an extensible architecture which transparently integrates natural language processing (NLP) techniques with wikis. It is designed to be deployed with any wiki platform, and the current prototype integrates a wide range of NLP algorithms such as keyphrase extraction, link discovery, text segmentation, summarization, or text similarity.

This paper investigates the use of sublexical units as a solution to handling the complex morphology with productive derivational processes, in the development of a lexical functional grammar for Turkish.
This paper reports on the ESPRIT project MELISSA (Methods and Tools for NaturalLanguage Interfacing with Standard Software Applications) ~. MELISSA aims at developing the technology and tools enabling end users to interface with computer applications, using natural-language (NL), and to obtain a precompetitive product validated in selected enduser applications. This paper gives an overview of the approach to solving (NL) interfacing problem and outlines some of the methods and software components developed in the project. ...
Problem localization Is the identification of the most slgnlflcant failures i n the AND-OR tree resulting from an unsuocass/ul attempt to achieve a goal, for instance, In planning, b a c k w a r d - c h n i n i n g inference, or top-down parnin~ We examine beurlstics and strategies for problem localization in the context of using a planner to check for pragmatic failures in natural language input to computer systems, such as a cooperative natural language interface to Unix .
The undisputed favorite application for natural language interfaces has been data base query. Why? The reasons range from the relative simplicity of the task, including shallow semantic processing, to the potential real-world utility of the resultant system. Because of such reasons, the data base query task was an excellent paradigmatic problem for computational linguistics, and for the very same reasons it is now time for the field to abandon its protective cocoon and progress beyond this rather limiting task. ...
( 'What you see is what you meant') is a user-interface technique which uses natural language generation (NLG) technology to provide feedback for user interactions. To date, the technology has been applied in a number of demonstrator applications, using customised, nonportable implementations. In this demonstration, we introduce a WYSIWYM library package, designed to be used as a modular component of a larger JAVA-based application.
The growing popularity of multimedia documents requires language technologies to approach automatic language analysis and generation from yet another perspective: that of its use in multimodal communication. In this paper, we present a support tool for COSMOROE, a theoretical framework for modelling multimedia dialectics. The tool is a text-based search interface that facilitates the exploration of a corpus of audiovisual ﬁles, annotated with the COSMOROE relations.
Recent work on the syntax-semantics interface (see e.g. (Dalrymple et al., 1994)) uses a fragment of linear logic as a 'glue language' for assembling meanings compositionally. This paper presents a glue language account of how negative polarity items (e.g. ever, any) get licensed within the scope of negative or downward-entailing contexts (Ladusaw, 1979), e.g. Nobody ever left. This treatment of licensing operates precisely at the syntax-semantics interface, since it is carried out entirely within the interface glue language (linear logic). ...
Acquiring information systems specifications from natural language description is presented as a problem class that requires a different treatment of semantics when compared with other applied NL systems such as database and operating system interfaces. Within this problem class, the specific task of obtaining explicit conceptual data models from natural language text or dialogue is being investigated. The knowledge brought to bear on this task is classified into syntactic, semantic and systems analysis knowledge.
We are currently developing a translation aid system specially designed for Englishto-Japanese volunteer translators working mainly online. In this paper we introduce the stratiﬁed reference lookup interface that has been incorporated into the source text area of the system, which distinguishes three user awareness levels depending on the type and nature of the reference unit. The different awareness levels are assigned to reference units from a variety of reference sources, according to the criteria of “composition”, “difﬁculty”, “speciality” and “resource type”.
The development of multi-channel digital broadcasting has generated a demand not only for new services but also for smart and highly functional capabilities in all broadcast-related devices. This is especially true of the television receivers on the viewer's side. With the aim of achieving a friendly interface that anybody can use with ease, we built a prototype interface system that operates a television through voice interactions using natural language.
An approach is described for supplying selectional restrictions to parsers in natural language interfaces (NLIs) to databases by extracting the selectional restrictions from semantic descriptions of those NLIs. Automating the process of finding selectional restrictions reduces NLI development time and may avoid errors introduced by handcoding selectional restrictions.
In this paper, we show that Higher-Order Coloured Unification - a form of unification developed for automated theorem proving - provides a general theory for modeling the interface between the interpretation process and other sources of linguistic, non semantic information. In particular, it provides the general theory for the Primary Occurrence Restriction which (Dalrymple et al., 1991)'s analysis called for.
We present a natural language interface system which is based entirely on trained statistical models. The system consists of three stages of processing: parsing, semantic interpretation, and discourse. Each of these stages is modeled as a statistical process. The models are fully integrated, resulting in an end-to-end system that maps input utterances into meaning representation frames.
Most attempts to incorporate non-literal aspects of communication into natural language interlaces have attempted to model human performance as closely as possible. The typical mode of communication in such an interface, in which system and user type alternately on a single scroll of pager (or scrolled display screen), has been used as an analogy to normal spoken human conversation in Wlllcll contmunicallon takes place over a similar half-duplex channel, i.e. a channel that only one party at a time can use witllout danger of confusion. ...
