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...
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...
To improve web search effectiveness and help personalized search applications, it is important to understand users' search process, especially the underlying information goal transitions and satisfaction judgment on result pages. Unlike previous work modeling the two types of hidden information separately, the paper proposes to simultaneously model them based on users' full search process, including...
As Deep Web contains tremendous well-structured data sources, how to integrate data sources in Deep Web has become a hotspot in current research. Accurately discovering and identifying Deep Web data sources related to a specific domain become key issues. We propose a Domain-Oriented Deep Web data source Discovery method (DO-DWD) and a novel Domain Identification strategy of Deep Web data sources (DIDW)...
In deep web, a significant amount of information can only be accessed through query interface of a back-end database, however, general search engine can not interact with the query interface, resulting in the myriad hidden and unvisible information can not be accessed. Therefore, this paper proposes a novel method of filling forms of deep web entries by importing ontology technique. Firstly, construct...
The Web has been rapidly deepened by many searchable databases online recently. Those databases can be accessed through form-based search interfaces that allow users to specify query conditions. For integrating Web databases, the very first challenge is to understand the search interface. Such a search interface can be considered as an interface schema with multiple attributes, however, the interface...
Mobile search is becoming increasingly important for mobile users as mobile devices are more widely used. Mobile search differs from standard PC-based Web search in a number of ways: (1) the user interfaces and I/O are limited by screen real estate and tiny key pads are tiny, (2) limited bandwidth and costly connection time, (3) increased local search due to mobility. These limitations result in more...
A new model will be introduced for Web information searching. Within the web, information is classified and then well defined according to its characteristics and functions. Associations are then set up logically between such information. Web information described as XML elements comes together with associations that are also XML elements. Given user's requests, the searching results can be inferred...
The 3D Visual Query Interface (3D VQI) is a Web-based database application that allows for shape-based searches in addition to more traditional text-based queries of the 3D vessel dataset. This interface allows researchers remote access to vessel collection that can be analyzed from anywhere in the world. The interface is divided into two sections with right half supporting the ability to draw profile...
In recent years, with the virtually unlimited amount of information sources, the deep Web is clearly becoming an important frontier for data integration. Schema matching is fundamental for supporting query mediation across deep Web sources. To integrate the millions of heterogeneous information sources and complete synonymous matching among the query interfaces, this paper developed an automatically...
Searching for medical information on the Web is popular and important. However, medical search has its own unique requirements that are poorly handled by existing medical Web search engines. This paper presents iMed, the first intelligent medical Web search engine that extensively uses medical knowledge and questionnaire to facilitate ordinary Internet users to search for medical information. iMed...
TheHotMap.com is an example of a next-generation Web search interface, wherein users are able to take an active role in the Web search process. Information that can assist searchers in their Web search tasks is presented in a visual manner. The system supports user interaction both during the query refinement process, as well as the search results exploration process. This paper describes the features...
In this paper, the Deep Web technologies are analyzed and discussed, and a middleware of finding and integrating Deep Web query interface automatically is proposed. This middleware extracts the attributes of query interfaces and judges them whether interfaces of Web databases by computing the similarity between them; it can also cluster query interfaces and construct an integrated query interface...
An increasing number of databases have become Web accessible through HTML form-based search interfaces, which is so-called deep Web. For full utilization of deep Web resources and improving Web intelligence, which is essential for many applications such as deep Web data collection and comparison shopping, they need to be extracted out and assigned meaningful labels. In this paper, we present a synchronous-annotation...
With the rapid development of Web, there are more and more Web databases available for users to access. At the same time, searchers often have difficulties in first finding the right sources and then querying over them. It becomes imperative to provide an integrated search system over Web databases, and integrating query interfaces is the first and the most important step. In this paper, using house...
In recent years, the Web is "deepened" rapidly and users have to browse quantities of Web sites to access Web databases in a specific domain. So, to build an unified query interface which integrates query interfaces of a domain to access various Web databases at the same time becomes a very important issue. In this paper, the schema characteristics of query interfaces and common attributes...
With the rapid development of the Internet, the Web is becoming the largest information repository of the world. Major efforts have been made in order to integrate the data of a specific domain on the Web. The traditional methods are largely done by few of system administrators which do not adapt to web scale. The construction of a web domain data integration system (WDDIS) becomes an urgent task...
In this study we report how different interfaces for searching the internet changed the strategies and information opportunities of voters as they searched for political information. A drop-down interface that helped users define specific queries was compared to a traditional typed- query interface. The drop-down interface resulted in a broader set of information opportunities. Voters using the drop-down...
