This paper describes a task repository, a device semantic interface to express device capabilities, and an advice algorithm that suggests the best task-device pair to satisfy a request. The purpose of the task repository is the adaptation of a pervasive environment (Ambient Intelligence) to support natural language applications, such as a natural language interface. The task repository has a pr...

We introduce a semantic interface into logic grammars to give a natural link to the semantic component of natural language understanding systems. The semantic interface contains five parameters, i.e. input, semantic information, new devices, generator, and output. These parameters specify the procedure of compiling a desired semantic theory into its corresponding logic programs. The semantic in...

Managers, in today's corporations, rely increasingly on the use of databases to obtain insights and updated information to make their decisions. This paper describes a flexible query interface based on fuzzy logic. Hence, queries in natural language with pre-defined syntactical structures are performed, and the system uses a fuzzy natural language process to provide answers. This process uses t...

In the present computing world, most new-generation database applications demand intelligent interface to enhance efficient interactions between database and the users. The most accessible interfaces for databases must be intelligent and able to understand natural language expressions. In this paper mapping of natural language queries to SQL is discussed. We propose a general architecture for a...

This paper discusses rational interaction as a methodology for designing and implementing dialogue management in ambient environments. It is assumed that natural (multimodal) language communication is the most intuitive way of interaction, and most suitable when the interlocutors are involved in open-ended activities that concern negotiations and planning. The paper discusses aspects that suppo...

User-adviser dialogues were collected in a typed Wizardof-Oz study (=man-behind-the-curtain study*). Thirty-two users had to solve simple statistics problems using an unfamiliar statistical package. Users received help on how to use the statistical package by typing utterances to what they believed was a computerized adviser. The observed limited set of users' grammatical and ungrammatical form...

Impression-based music retrieval is the best way to find pieces of music that suit the preferences, senses, or mental states of users. A natural language interface (NLI) is more useful and effective than a graphical user interface for impression-based music retrieval since an NLI interprets users’ spontaneous input sentences to represent musical impressions and generates query vectors for music...

In this paper, we describe an architectural framework for the development of natural language interfaces to agent systems. Since the communication between human and artificial agents is mostly task-related, the focus of the suggested architecture is on action representations as core structure and thread in the overall processing. The architectural framework we suggest is based on various forms ...

The development of realistic virtual actors in many applications, from user interface to computer entertainment, creates expectations on the intelligence of these actors including their ability to understand natural language. Based on our research in that area over the past years, we highlight specific technical aspects in the development of language-enabled actors. The embodied nature of virtu...

Programming, i.e., the act of creating a runnable artifact applicable to multiple inputs/tasks, is an art that requires substantial knowledge of programming languages and development techniques. As the use of software is becoming far more prevalent in all aspects of life, programming has changed and the need to program has become relevant to a much broader community. In the interest of broadeni...
