Natural Language Interfaces to Conceptual Models
… currently requires the use of formal query languages (e.g., SeRQL or SPARQL) which pose significant difficulties for non-expert users. One way to lower the learning overhead and make ontology queries more straightforward is through a Natural Lan- guage Interface (NLI). While there are …

Natural Language Interfaces for Data Analytics
… in which users rely on their own natural language to analyze and visualize data. To that end, we develop three different approaches (unsupervised, rule-based, and supervised) to infer formal specifications from natural language utterances. Contrary to most other work, we developed these …

Improving the portability of natural language interfaces through learning
One major concern with natural language interfaces is dealing with the problem of porting the system from one domain to another. Early approaches required that significant parts of the system be rewritten. Improvements have been made to the point that a system can be configured for a new database …

Natural Language Control for for Visually Interactive Decision Support Tools in Supply Chain Management
… and understand. A solution for this is natural language interfaces, allowing users to use natural language commands to control the visualization. Additionally, natural language interfaces can be difficult to implement, and require applications specific programming or training. This thesis …

Parsing and generation of unification grammars
… between input and output in interactive natural language interfaces. A Prolog implementation of the unification-based parser and DAG unifier is provided. The DAG unifier includes extension to handle disjunction and negation.

Design and evaluation of CNC-user interfaces
… manufacturing plants. In recent years, CNC-user interfaces have been evolving from CNC command languages to menu based and direct manipulation interfaces. However, there have been few efforts to evaluate CNC-user interfaces and to identify those interface features that have major effects on the …

Learning precise partial semantic mappings via linear algebra
In natural language interfaces, having high precision, i.e., abstaining when the system is unsure, is critical for good user experience. However, most NLP systems are trained to maximize accuracy with precision as an afterthought. In this thesis, we put precision first and ask: Can we learn to map …

Crowd-supervised training of spoken language systems
Spoken language systems are often deployed with static speech recognizers. Only rarely are parameters in the underlying language, lexical, or acoustic models updated on-the-fly. In the few instances where parameters are learned in an online fashion, developers traditionally resort to unsupervised …

A natural language interface for querying graph databases
… no understanding of database schemes and query languages. Providing a tool that translates natural language queries into structured queries allows people without this technical knowledge or specific domain expertise to retrieve information that was previously inaccessible. Many existing natural …

Model-based user interaction for accessing electronic news
Natural language interfaces support human-machine interactions in a way that is natural and that does not require elaborate user training. The two main problems in human-computer dialog are resolution of ambiguity and incompleteness. A model-based architecture is introduced in this thesis that …

An update expert and response generator for a transportable natural language interface to database management systems
Fully transportable natural language interfaces to database management systems (DBMS) have been under study for some years I but until now I all have suffered from a lack of response ability and lack of natural language update ability. Response generation is relatively easy to overcome, but the …

The pragmatics of the modern Greek grammatical system
… several other disciplines, including natural language acquisition, first and second language teaching as well as natural language interfaces, human-machine interaction, speech processing systems, and on-line language learning systems.

Adapting Transformers for Structured Data Domains
… domains beyond their traditional use in natural language processing (NLP). We revisit key elements of the transformer framework - including input representations, attention formulations, auxiliary tasks, prediction layers and loss functions - and adapt them to better suit the structure and …

Aging and Referential Communication: Insights from Interactions with Artificial Agents
… however, less is known about changes in the language domain. Language is a fundamental component of everyday communication, not only in the context of interactions with humans but also with artificial agents. There are now increasing multidisciplinary efforts to develop technologies that …

Natural language interface to relational database: a simplified customization approach
Natural language interfaces to databases (NLIDB) allow end-users with no knowledge of a formal language like SQL to query databases. One of the main open problems currently investigated is the development of NLIDB systems that are easily portable across several domains. The present study focuses on …

Embodying conversational characteristics in a graphical user interface
… ideas and features. One of these was its natural language user interface. Today, the trend has moved away from natural language interfaces towards graphical ones although the argument in favour of natural language user interfaces, both from Human Computer Interaction and natural language …

Spoken Language Understanding: from Spoken Utterances to Semantic Structures
… there have been several projects on Spoken Language Understanding (SLU). In the early nineties DARPA ATIS project aimed at providing a natural language interface to a travel information database. Following the ATIS project, DARPA Communicator project aimed at building a spoken dialog system …

Towards Natural And Robust Human-Robot Interaction Using Sketch And Speech
… of more natural and flexible human-robot interfaces, allowing humans to communicate with machines using means such as speech, drawing, gesturing, etc. These methods are still in their infancy, and while they offer more human-like interaction with computers, ensuring that the user's …
