Most of fire detection system used the heuristic fixed threshold values in their specific methods. However, input images may be changed, in general, so the heuristic fixed threshold values used in the fire detection systems might be modified on a case by case basis. In this paper, an automatic fire detection system without the heuristic fixed threshold values was studied. We presented an automatic method using the statistical color model and the binary background mask. We did the experiment using 600 frames from 6 typical different fire video clips. As the experimental results the proposed method showed a good performance of about overage 85% detection rate without false positive, compared withthe other methods withthe heuristic fixed threshold values.
this paper presents the concept of surface text patterns for extracting purpose data from the web. In order to obtain an optimal set of patterns, we have developed a method for learning purpose patterns automatically....

Nowadays, hand-held devices are being used more and more, especially for web navigation. But the small screen size of these devices requires adapting web page contents to be browsed more conveniently. A fundamental step in a successful automatic adaptation process of a web page is perception its visual layout and mining its Document Object Model (DOM) structure. In this paper, we present a new web-adapted supervised segmentation algorithm dedicated to vibro-tactile access on touch-screen devices. this suggested algorithm is fundamental in our framework whose aim is enhancing the ability of Visually Impaired Persons (VIP) to understand the 2-dimension web page layout by converting web pages into vibrating pages using a graphical vibro-tactile language. A comparison between automatic and manual segmented pages is presented. the objectives of this comparison are, on the one hand, to know how users understand web page layout structure based on their visual perception, and on the other hand, to explore the main differences between automatic and manual segmentation.

the semantic web is a general vision for supporting knowledge-based processing across the WWW and its successors. As such, semantic webtechnology has potential to support the exchange and processing of complex NLG data. this paper discusses one particular approach to data sharing and exchange that was developed for NLG - the RAGS framework. this was developed independently of the semantic web. RAGS was relatively complex and involved a number of idiosyncratic features. However, we present a rational reconstruction of RAGS in terms of semantic web concepts, which yields a relatively simple approach that can exploit semantic webtechnology directly. Given that RAGS was motivated by the concerns of the NLG community, it is perhaps remarkable that its aspirations seem to fit so well with semantic webtechnology.

Effective provision of government services implies that, besides being provided online, services become available through other channels, are organized according to citizen's expectations, are accessible to everyone, anytime and anywhere, and include information from unstructured sources. It is also essential to provide the tools that allow citizens to correctly identify the services they need. In this paper we will discuss how it is possible to improve e-gov service delivery by using human language technologies. We argue that these technologies can contribute to: deliver services in more inclusive manners;provide human centered and multilingual service and support;and include non-structured information scattered across different sources.

this study consists of two experiments∗. Experiment A investigates speaker-information distribution in the parametric domain. Experiment B compares different weighting strategies for speaker-information enhancement. the results indicate that weightings based on speaker-information distribution in the parametric domain yield better speaker recognition performance.

the objective of this work is to develop business-to-business processes of electronic markets using web services in order to facilitate the execution of these processes in different electronic markets. the main contribution of this approach is the promotion of interoperability, just-in-time integration, and reduction of complexity. In specific, the Cooperation, Orchestration and Semantic Mapping of web Services (COSMOS) tool, which is an integrated development environment that enables the creation, design and modification of executable business processes based on the Business Process Execution language, is used for the integration of business-to-business processes of a Virtual Industrial Market into a fully functional web-based environment.

Since web users' queries are often too short, an accurate and interactive speech interface is believed very helpful, especially for WAP-based web search engines. To provide high accurate speech recognition and effective interactive search, a rigid and live webthesaurus that contains users' search terms plus a set of relations between their associated terms is highly in demand. the purpose of this paper is intended to present a log-based approach for live thesaurus construction. Based on the live thesaurus, certain kinds of users' information behaviors could be characterized and a more effective voice-based search engine could be developed.

A multi-agent learning system model is presented to solve the problems existing in the present remote learning system, such as the monotonous pattern and passive educating. Integrated with intelligent agent technology, the multi-agent learning system gives tin agent capability description language, on the basis of which we suggest relevant personal grouping strategy and learning task allocation strategy. Furthermore, it uses compensates mechanism to encourage the agent cooperation, state-space-search theory to enable the MAS system to have the stronger problem solving ability both of which can meet demand of active learning for the learners and to some extent economize communication of system and save the communication in the system in certain degree.
