Withthe further development of informationtechnology, web application, built in the traditional object-oriented way, is becoming difficult in application's upgrades and changes. In general, the application breaks down into independent modules by functionality, each of them is used to deals with specific business logic, is an effective and graceful design. the module's feature of high cohesion ensures that the application is easily modified;the characteristic of low coupling makes the application easy to optimize and expand. However, it is very difficult to construct a modular web application with Java language directly as Java do not have the nature of modularity at language-level. through the study of OSGi specification, this paper divides the module into Business and Function Bundles and applies them in architecture design for web applications based on OSGi.

this paper presents a novel approach to spoken document retrieval where the speech recognition and information retrieval components are more tightly integrated. this is done by developing new recognizer and retrieval models where the interface between the two components is better matched and the component goals are consistent withthe overall goal of the combined system. Experiments on radio news data show that the integrated approach can improve performance by 28% over a baseline system.

Document similarity is basic for information Retrieval. Cross Lingual (CL) similarity is important for many data processing tasks such as CL palgiarism detection and retrieval and document quality assessment. We study CL similarity based on the Explicit Semantic Association (ESA) adapted to a cross lingual setting with focus on Arabic. We compare the degree to which CL similarity testing performs where one of the language is Arabic with its monolingual counterpart for various text chunk sizes. We describe the used infrastructure and report on some of the testing results, study the possible sources of encountered weaknesses and point to the possible directions for improvement.

In the Internet economy, it has become a crucial task of electronic business to monitor and optimize web sites, their usage and online marketing success. web analytics, which is defined as the measurement, collection, analysis and reporting of Internet data, is an effective instrument of website management. First, this paper describes the technical functionality and use of web analytics and discusses different web metrics. Second, a fuzzy web analytics approach is proposed, which makes it possible to classify metrics precisely into more than one class at the same time. third, a fuzzy web metrics index has been developed for multidimensional, intelligent web analysis. Fuzzy logic enables computing with words and more intuitive, human-oriented queries, segmentation and descriptions of metrics in natural language. Finally, a web analytics framework is suggested to analyze and control key performance indicators in a web controlling loop.
We present a performance evaluation framework for Spoken language Understanding (SLU) modules, focusing on three elements: (1) characterization of spoken utterances, (2) experimental design, and (3) quantitative evalu...

the booming webtechnology stimulates computer-based e-education which is considered to be an appropriate lifelong education approach in this era due to the spatial and temporal convenience. In this paper we propose a service-oriented agent e-education framework based on the next generation web, viz. semantic web. Compared withthe framework on which the e-education performs now, this new framework has many advanced properties due to the use of intelligent agents and is expected to perform an automated style for the future education.
We explore the feasibility of contextual healthiness classification of food items. We present a detailed analysis of the linguistic phenomena that need to be taken into consideration for this task based on a specially...

More and more data is produced in the form of videos, which are opaque to textual queries. To allow searching in video data collections, two problems have to be solved: the automatic generation of a searchable index, and the effective search in the automatically produced and therefore imperfect index. the ISL View4You system is a prototype of a video indexing and retrieval system which both generates the index and provides a search engine to access it. An end to end evaluation was carried out using real-world data and queries from naive subjects. From the results it can be concluded, errors of the overall system are not due to the index generation, but are introduced by the information retrieval engine (the search). therefore, the focus of this paper is a comparison of two different search algorithms, LSI (latent semantic indexing) and Okapi (a avor of the traditional classic vector model approach). the evaluation is carried out on the automatically produced index on a relatively small database, which allows for full manual relevance judgement.
