Meta search engines can solve the low recall disadvantage of individual search engines to a certain degree. Starting with the present situation and classification of search engines, this paper made a brief introduction to the concept of meta search engines, and focused on the basic system structure and key technologies in their individual modules, finally made a short summary.
As a member of the search engine industry, the author observes that the community appears to be perversely enamored by the last good idea back at the dawn of the Web. Sure, there have been tweaks to relevance ranking and substantial gains in scalability to keep up with the growth of the Web and electronic publication repositories. But overall, there has been a stupendous lack of radical innovation...
This paper presents the results of a questionnaire on user behaviour during searching the Web as part of information gathering tasks. In this study, users' Web activities related to finding information, comparing information, managing information, and re-finding information, using different Web search and navigation tools, used for information gathering tasks are explored. The results indicate that...
The following topics are dealt with: user behavior; intention aware computing; Internet LAN based RFID; intrusion detection system; document analysis; Web service; search engine; machine learning; neural network; collaborative communication; virtualized server; collaborative learning; video summary; computer simulation; fingerprint image matching; data analysis; Bayesian network; text visualization;...
The internet resources are very rich, and the traditional search engines can accelerate the speed of network information retrieval. But the bilingual translation comparison pages' information in intemet are not fully used. So the combine of personalized search engine and the bilingual auxiliary translation become an important research subject at present. In this paper, basing on the large-scale network-based...
To improve the retrieval efficiency and performance of the large scale information retrieval systems, analyzed existing replacement algorithm for WEB caching, due to the diversity of the WEB traffic pattern, the traditional algorithms for cache updating can not be used in WEB environment effectively. In this paper, with click-through data analysis, a inverted file replacement algorithm for WEB caching...
The characteristic of dynamic websites is that they include hidden contents, and this huge repository is only accessible via the website interfaces. This is a vital capability of all search engines, thus providing the users with links that are more relevant and ranked according to their needs. The drawback of most search engine algorithms is that they rank pages based on hyperlinked relative importance...
Nowadays, Internet users are familiar with the Web searching process; and searching is the most common task performed on the Web. However, the web search is especially difficult for beginners when they try to utilize a keyword query language. Subsequently, beginners usually try to find information with ambiguous queries. Users receive non-relevant information in response to queries. Our goal is to...
Image annotation is a promising approach to bridging the semantic gap between low-level features and high-level concepts, and it can avoid the heavy manual labor. Most existing automatic image annotation approaches are based on supervised learning. They often encounter several problems, such as insufficiency of training data, lack of ability in dealing with new concept, and a limited number of semantic...
Nowadays the information on the Internet is increasing rapidly and being updated in real time. How to acquire the information you need quickly and accurately is a primary research topic. According to the defect of current search engines, this paper presents a model of personal information, to improve examining allowing rate of information search and to perfect mutual function between users. This paper...
With the development of the Grid computing, increased attention is paid to services and user personalization. How to search and schedule the most suitable service for an end user direct affects the popularization use of service oriented Grid. Inspired from the mode of web search engine, such as Yahoo, Google, this paper proposes an innovative service searching and scheduling algorithm (SPSE: Service...
For the current shortcomings of the agricultural information system, the paper introduces the Google Maps-based electronic farm system for the information service of the end-user ubiquitous demand. With running instance of the system the paper shows the implementation methodology and implementation process for the key part of the system. Given the design principles which are the simplifying of the...
With the tremendous growth of the Web and the contents difference, users need specialized accurate results depending on their behavior and varying according to their interest. In this paper, we introduce A personal search engine which provides results relevant to the user's interest. Our search engine depends on three factors to ensure relevant and accurate results. The first factor is the degree...
There are several semantic sources that can be found in the Web that are either explicit, e.g. Wikipedia, or implicit, e.g. derived from Web usage data. Most of them are related to user generated content (UGC) or what is called today the Web 2.0. In this talk we show several applications of mining the wisdom of crowds behind UGC to improve search. These results not only impact the search performance...
Searching for medical information on the Web has become highly popular, but it remains a challenging task because searchers are often uncertain about their exact medical situations and unfamiliar with medical terminology. To address this challenge, we have built an intelligent medical Web search engine called iMed. iMed introduces and extends expert system technology into the search engine domain...
Our goal is to use the vast repositories of available open source code to generate specific functions or classes that meet a user's specifications. The key words here are specifications and generate. We let users specify what they are looking for as precisely as possible using keywords, class or method signatures, test cases, contracts, and security constraints using a simple, Web-based interface...
The information resources on the Web become increasingly global in nature. Their amount is continuingly growing. A solution to summarize the retrieved pages on the fly and to design the simplest user interface is possible approach to improve and speed up the retrieval of the information from the Web. This paper discusses the algorithms to implement the aforementioned approach and results of preliminary...
According to Internet World Stats and EUROPA, ldquouse search enginerdquo is the highest proportion of Internet individual activities. Therefore, despite functions, databases and technology update of search engine development, it should be considered the usability, operation, and user behavior. This article explore from the development process of the Web and search engines, and summarized the current...
With the advent of Google Earth, it is an interesting idea that we build a Web-3D virtual trading community where users can have their own houses or offices and engage in trading activities with each other. Thus, it is necessary to develop an intelligent project agency (IPA) to deal with the huge amount of project information. IPA is an effective way of not only filtering and clustering the users'...
In order to provide intelligent and integrative Web map service applications for common users, this paper introduced agent-based methodology to realize flexible Web map services aggregation on the Internet. According to the service aggregation procedure, we designed modules of agent-based user interface, service registry, service planning and service aggregation, explained the functions of role-oriented...
