SGStudio (Semantic Grammar Studio) is a grammar authoring tool that facilitates the development of spoken dialog systems and speech enabled applications. It enables regular software developers with little speech/linguistic background to rapidly create quality semantic grammars for automatic speech recognition (ASR) and spoken language understanding (SLU). This paper introduces the framework of ...

We present a family of priors over probabilistic grammar weights, called the shared logistic normal distribution. This family extends the partitioned logistic normal distribution, enabling factored covariance between the probabilities of different derivation events in the probabilistic grammar, providing a new way to encode prior knowledge about an unknown grammar. We describe a variational EM ...

The acquisition of grammar from a corpus is a challenging task in the preparation of a knowledge bank. In this paper, we discuss the extraction of Chinese grammar oriented to a restricted corpus. First, probabilistic context-free grammars (PCFG) are extracted automatically from the Penn Chinese Treebank and are regarded as the baseline rules. Then a corpusoriented grammar is developed by adding...

In this paper we present SINTESI, a system for the knowledge extraction from Italian inputs, currently under development in our re,search centre. It is used on short descriptive diagnostic texts, in order to summarise their technical content and to build a knowledge base on faults. Often in these texts complex linguistic constructions like conjunctions, negations, ellipsis and anaphorae are inv...

\ OX is a Natural Language Processor whose knowledge ran be extended by interaction with a user about these objects. The VOX analyzer uses information obtained in extensibility sessions to analyze novel text. 1.1 EXAMPLES VOX consists of a text analyzer and an extensibility system that share a knowledge base The extensibility system lets the user add vocabulary, concepts, phrases, events, and s...

This paper presents a technique for product configuration modelling based on object-orientation and attribute grammars. The technique allows efficient interactive configurator tools to be generated for specified product families. Additional benefits include a high degree of checkability, early validation, readability, and reusability. The technique is particularly aimed at mass-customization pr...

In this article we present a Spanish grammar implemented in the Linguistic Knowledge Builder system and grounded in the theoretical framework of Head-driven Phrase Structure Grammar. The grammar is being developed in an international multilingual context, the DELPH-IN Initiative, contributing to an open-source repository of software and linguistic resources for various Natural Language Processi...

Background: The present study aimed to analyze the situation of knowledge management among the faculty members in the four components, including creation, linking, organization and storage, and application. Methods: This is a survey research and the results are presented descriptively and analytically. The study tool was a questionnaire of knowledge management with 84 questions (creation of kno...

This study has aimed to compare the effects of two types of form-focused instruction, i.e. de-contextualized focus-on-forms instruction versus meaning-centered contextualized focus-on-form instruction, on the development of grammatical knowledge of Iranian high-school students. Two groups of male high-school first graders participated in this study.  One group was taught through de-contextualiz...
