This article describes a knowledge oriented semantic parser designed for spoken dialog systems. It merges some syntactic and semantic aspects into a single frame to get robust and efficient analyses. The knowledge is entirely described withing an XML formalism. The parser takes as input either a string of words (the 1-best word sequence) or a word-lattice coming from an ASR (Automatic Speech Recognition)...
This paper describes an approach to the modular specification of XML processing tasks. The approach is language-oriented: it considers the programs that process a type of XML documents to be processors (e.g., compilers or interpreters) for the markup language used in these documents. In addition, it encourages the declarative specification of these processors through attribute grammars. In doing so,...
This paper presents the design and implementation of voice interaction system based on PC in service robots intelligent space. Microsoft Speech SDK 5.1 and VoiceText are used for speech recognition and speech synthesis, respectively. The SQL Server 2000 is adopted to design dialogue base of dialogue management module. After getting information from intelligent space, intelligent space decision support...
Additional structure within free texts can be utilized to assist in identification of matching items and can benefit many intelligent text pattern recognition applications. This paper presents an incremental evolving fuzzy grammar (IEFG) method that focuses on the learning of underlying text fragment patterns and provides an efficient fuzzy grammar representation that exploits both syntactic and semantic...
Many e-learning tools are based on domain-specific languages (DSLs) targeted to the educational domain. Thus, methods and techniques from the programming language community can help in developing these tools. In this paper, we show how attribute grammars, a well-known declarative specification method for the syntax and semantics of programming languages, can facilitate the production and subsequent...
With the rapid development of model-driven engineering (MDE), domain-specific modeling has become a widely used software development technique. In MDE, metamodels represent a schema definition of the syntax and static semantics to which an instance model conforms (i.e., a model conforms to its metamodel in a similar manner to how a program conforms to a grammar). However, in order to address new feature...
The C language integrated development environment (IDE) with data accessing can help the programming beginners fast grasp the basic language grammars and the drawing functions of C language. It also helps C language to access relational data, no relational data and the cluster communication port (COM) data conveniently. The system has the characters such as window docking freely, the striking grammar,...
Many enterprise applications can benefit from the use of wireless sensors, for example for monitoring location and state of goods. While modern backend IT systems use elaborate Service Oriented Architectures based on Web Services, the resource constraints of sensor nodes require highly optimized embedded programming and proprietary networking protocols. This paper aims at bridging this gap by extending...
Today the world wants XML. Extended Markup Language (XML) is a universal markup language for exchanging and publishing data in web applications. There are other Markup Languages such as MathML, CML, and MusicML etc which are specifically designed for particular purpose. Data containing system does not wish to expose its schema for simple security and privacy reasons. So writing query against is not...
In this article, we propose an improved structured and progressive electronic dictionary for the Arabic language (iSPEDAL) which can be presented in the form of a relational database or in the form of an XML document which can be easily exploitable using suitable query languages. Indeed, many Arabic dictionaries are found but are not structured and not directly exploitable since they are in flat textual...
One of the critical challenges in embedded sensor actor networks is the communication between the diversity of widespread nodes. XML-based message formats are already widely adopted in other IT domains such as the Web and would be perfectly suited for data exchange in heterogeneous environments. Despite all its strengths, the common markup language cannot be adopted on small embedded devices with...
This paper discusses a transcoder, TC-GXML, designed and developed by us as a part of an ongoing research project related to design and development of a speech based webbrowsing system for visually challenged. It is always easier to develop a visual application than a nonvisual application based on speech interface. There are issues like Non-Standard format of HTML, due to which it is difficult for...
The on-going project aiming at the creation of the National Corpus of Polish assumes several levels of linguistic annotation. We present the technical environment and methodological background developed for the three upper annotation levels: the level of syntactic words and groups, and the level of named entities. We show how knowledge-based platforms Spejd and Sprout are used for the automatic pre-annotation...
With the promotion and application of XML standards, The research hotspot in database domain has emerged, namely, how to effectively manage the large-scale XML data. XQuery Update Facility, which proposed by W3C in 2008 has become the grammar and semanteme standard for the realization of XML data updating. Based on this standard, this paper presents a XML update pattern which seamlessly integrated...
Regular hedge languages are an extension of regular tree languages that received renewed attention since their recognition as a formal model of XML schemata. They share several properties with regular languages, but their study is more involved because we need to analyze regularities of sequences of trees instead of words. We show that one shared property is the existence of only finitely many language...
In this article, we propose a software framework couples voice command definitions with existing interaction code, automating the task of creating a new grammar to be used by the recognizer engine. A new listener component for the Xj3D was created, which makes transparent to the user the integration between the 3D browser and the recognizer. The approach assumes the adoption of an independent speech...
