this paper describes on application system that provides web sites withthe location information of the internet users using their IP addresses. the IP addresses are very large size of data(2(32)) and the response time of the system should be short enough to be capable of dealing with large number of requests (thousands of queries per second) of web sites. Location information retrieval is similar to network router issue in finding destination of packets with IP addresses but also much difference in protocol, data size and complexity. the location information system using IP address is comprised of array, trie, hashing, and memory database. Experiments of each data structure and their performances are compared and discussed.

the formation of Sematic web Services (SWS) makes it possible to discover, implement and compose web service automatically. OWL-S, the description language of Sematic web Service, increases flexibility of web service description, enriches expressiveness of it and provides a capability-based mechanism of web service discovery. We introduce a automatic discovery algorithm of SWS in this paper. the property of web service including Input, Output, Pre-condition and Effect is matched with user's requirement, and then we calculate matchmaking degree. We can also combine UDDI withthis matchmaking in order to get better result of web service discovery for users.

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.

A web BBS is one of representative interfaces in a web community. web queries for the BBS have the inefficiency that a query optimizer should read all the contents of the BBS stored in a database every query, since web mechanism cannot memorize the previous state. In addition, the queries in a web BBS should guarantee the 'random page jump' property characterizing the BBS. In this paper, a query optimization method and its SQL statements for a web BBS are proposed using Oracle's new facilities - a window-based analytic function and a function-based index. Also, the proposed queries are verified through applying them to a real web community, showing that they make meaningful improvements in query performance.

the knowledge contained in digital lectures and articles used in eLearning platforms like Moodle and Blackboard, is creating new demands for intelligent retrieval mechanisms. One basic approach in support Of such retrieval mechanisms is the generation of semantic annotation, based on ontologies describing boththe field and the structure of the texts themselves. Many current approaches use statistical methods similar to the ones employed by Google to find correlations within the texts. While successful and efficient, this approach fails to take advantage of the additional information provided by the structure of the sources, or, i.e. the upper ontology used by the author. mArachna is based on natural languageprocessing techniques, taking advantage of characteristic linguistic structures defined by the language used in mathematical texts. It creates a knowledge base from the mathematical relations presented in a text, mapping the ontology onto the structure of the knowledge base.

this paper presents a Korean spacing approach which employs an improved Viterbi segmentation model. Traditional Viterbi segmentation using the word unigram language model is simple and fast, but has two problems: data sparseness and improper preference of fewer segments. To overcome these limitations, the segmentation model is extended by employing a split probability based on character bigram. Contextual information is selectively used for further resolution of spacing ambiguities without much increase of the complexity Experimental results show that the extended model performs better than the traditional segmentation model. Futhermore, compared to the state of the ail system, our approach achieves better efficiency in terms of processing time without losing significant accuracy.

In semiotics, pragmatics is about purpose, context, communication and negotiation. the concept of pragmatics could be introduced into the web service technology to become the pragmatic web service. Intelligent agents play a vital role in this web service architecture especially for web service integration to provide better solution based on service consumers' overall requirement. In this paper, intelligent agents and are described to manage users' intention, service context, information communication and negotiation between service consumers and service providers. In addition, the agents need to be able to analyze user's requirements, construct web service abstract work flow and rank the semantic equivalent web services from the service registry. Section2 describes the research background of pragmatic web services. Section3 is about the basic structure of pragmatic web service agents and section4 concerns the agent-based web service integration.

information Retrieval (IR) techniques have been extensively studied since late 1940s and achieved great success evidenced particularly by popular online search engines. However, various classical information retrieval models also have witnessed criticism for emphasizing computation with occurrence of words while ignoring semantics (i.e. meaning of words, search context and etc). Research of the Semantic web in recent years has provided an opportunity to migrate from mere word-computing to semantic-enhanced information search and retrieval. In this paper, we describe a methodology by combing the Semantic web technologies, information extraction and social network analysis techniques to elicit semantics from available data in order to develop a semantic-enhanced information search and retrieval system.
