SBVR is becoming more and more popular as the metamodel for defining vocabulary based business rules. In an extended form SBVR can be used to declare a whole spectrum of business rules including control-flow and organizational rules. Enforcing the rules of the business in information systems is however not straightforward. SBVR leaves open the gap between defining business rules and actually en...

This paper studies the idea of removing low-frequency words from a corpus, which is a common practice to reduce computational costs, from a theoretical standpoint. Based on the assumption that a corpus follows Zipf’s law, we derive tradeoff formulae of the perplexity of k-gram models and topic models with respect to the size of the reduced vocabulary. In addition, we show an approximate behavio...

Collaborative navigation systems provide a useful way for virtual groups to share information through the web. However, the common set of features of these tools is not enough to offer a more face-to-face-like browsing experience. To fill this gap, this paper presents a novel collaborative web browsing proposal, which aims at integrating notably flexible management of sessions, the maintenance ...

abstract the present study aims at analyzing efl learners’ attitudes towards motivating factors in learning vocab-ulary. a mixed-methods approach was used to conduct the study. in the qualitative analysis, iranian efl learners’ attitudes towards learning vocabulary were investigated through a semi-structured interview en-compassing 36 participants. subsequently, a 56-item ‘motivation for voca...

It is well established that extensive reading promotes the incidental learning of L1 and L2 receptive vocabulary; however, little is known about its effectiveness on productive gains in vocabulary knowledge. This paper investigates the extent to which extensive reading combined with writing tasks promotes productive vocabulary growth of Japanese university students. To examine changes in vocabu...

This paper introduces case frames as a way to provide a more meaningful structure to vocabulary mappings used to bridge the gap between laymen and legal descriptions of court proceedings. Case frames both reduce the ambiguity of queries, and improve the ability of users to formulate good quality queries. We extend the BestMap ontology with a formalisation of case frame based mappings in OWL 2, ...

In this paper we present a system named EasyCmd that provides voice navigation on the desktop of Microsoft Window 9x system. Speech recognition engine for EasyCmd is much similar to that for dictation machine. Statistical Knowledge Based Frame Synchronous Search algorithm (SKBFSS) and Word Search Tree (WST) technologies are applied for acoustic decoding. Recognition Score Gap (RSG) is used for ...

the purpose of this study was to investigate the impact of blended learning and multimedia software on iranian esp students' vocabulary learning. to this end, 120 iranian esp learners were assigned to two groups: the experimental and control groups. the experimental group received instructions through multimedia software while the control group received traditional instructions. the data were c...

Words to express relations in natural language (NL) statements may be different from those to represent properties in knowledge bases (KB). The vocabulary gap becomes barriers for knowledge base construction and retrieval. With the demo system called NL2KB in this paper, users can browse which properties in KB side may be mapped to for a given relational pattern in NL side. Besides, they can re...

This paper studies the integration of lexical semantic knowledge in two related semantic computing tasks: ad-hoc information retrieval and computing text similarity. For this purpose, we compare the performance of two algorithms: (i) using semantic relatedness, and (ii) using a conventional extended Boolean model [13] with additional query expansion. For the evaluation, we use two different tes...
