MetaSeek is an image metasearch engine developed to explore the querying of large, distributed, online visual information systems. The current implementation integrates user feedback into a performance-ranking mechanism. MetaSeek selects and queries the target image search engines according to their success under similar query conditions in previous searches. The current implementation keeps track of each target engine's performance by integrating user feedback for each visual query into a performance database. We begin with a review of the issues in content-based visual query, then describe the current MetaSeek implementation. We present the results of experiments that evaluated the implementation in comparison to a previous version of the system and a baseline engine that randomly selects the individual search engines to query. We conclude by summarizing open issues for future research 相似文献

In this paper, we present two new list fusion strategies for the collection fusion problem in web metasearch. The new approaches
fall in the category of isolated methods since they consider as input the lists obtained by different search engines only, plus a fuzzy degree of relevance in one
of the methods. In the latter case, we employ a recently proposed approach for the representation of fuzzy preferences, namely,
RL-preference relations. A remarkable contribution of the approaches is that the result of the fusion is an ordered list of
indistinguishable groups of documents. This kind of output represents a good compromise between understandability and accuracy
of the result. We have illustrated the performance of the method by means of several experiments and a comparison with other
web metasearchers. 相似文献

XSLT is a popular language for implementing both presentation templates in Web applications as well as document and message converters in enterprise applications. The widespread adoption and popularity of XSLT raises the challenge of efficiently managing the evolution of significant amounts of XSLT code. This challenge calls for guidelines and tool support for developing maintainable XSLT code. In this setting, this paper addresses the following question: Can the maintainability of XSL transformations, measured in terms of code churn in the next revision of a transformation, be predicted using a combination of simple metrics? This question is studied using a dataset extracted from open-source software project repositories. An outcome of this empirical study is a set of statistical models for predicting the maintainability of XSL transformations with relatively high accuracy. In addition, by analyzing the major influencers of code churn in these models, the paper identifies guidelines for designing XSL transformations with reduced future churn. 相似文献

XML is a markup language used to describe data or documents. The main goal of XML is to facilitate the sharing of data across diverse information systems, especially via the Internet. XML Stylesheet Transformations (XSLT) is a standard approach to describing how to transform an XML document into another data format. The ever‐increasing number of Web technologies being used in our everyday lives commonly employs XSLT to support data exchange among heterogeneous environments, and the associated increasing burdens on XSLT processors have increased the demand for high‐performance XSLT processors. In this paper, we present an XSLT compiler, named Zebu, which can transform an XSLT stylesheet into the corresponding C program. The compiled program can be used to transform documents without the processing of XSLT stylesheets. The results of experimental testing using standard benchmarks show that the proposed XSLT compiler performs well in processing XML transformations. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

A neural network-based intelligent metasearch engine 总被引:12,自引:0,他引:12
Determining the relevancy of web pages to a query term is basic to the working of any search engine. In this paper we present a neural network based algorithm to classify the relevancy of search results on a metasearch engine. The fast learning neural network technology used by us enables the metasearch engine to handle a query term in a reasonably short time and return the search results with high accuracy. 相似文献

Rank aggregation mechanisms have been used in solving problems from various domains such as bioinformatics, natural language processing, information retrieval, etc. Metasearch is one such application where a user gives a query to the metasearch engine, and the metasearch engine forwards the query to multiple individual search engines. Results or rankings returned by these individual search engines are combined using rank aggregation algorithms to produce the final result to be displayed to the user. We identify few aspects that should be kept in mind for designing any rank aggregation algorithm for metasearch. For example, generally equal importance is given to the input rankings while performing the aggregation. However, depending on the indexed set of web pages, features considered for ranking, ranking functions used etc. by the individual search engines, the individual rankings may be of different qualities. So, the aggregation algorithm should give more weight to the better rankings while giving less weight to others. Also, since the aggregation is performed when the user is waiting for response, the operations performed in the algorithm need to be light weight. Moreover, getting supervised data for rank aggregation problem is often difficult. In this paper, we present an unsupervised rank aggregation algorithm that is suitable for metasearch and addresses the aspects mentioned above.We also perform detailed experimental evaluation of the proposed algorithm on four different benchmark datasets having ground truth information. Apart from the unsupervised Kendall-Tau distance measure, several supervised evaluation measures are used for performance comparison. Experimental results demonstrate the efficacy of the proposed algorithm over baseline methods in terms of supervised evaluation metrics. Through these experiments we also show that Kendall-Tau distance metric may not be suitable for evaluating rank aggregation algorithms for metasearch. 相似文献

A development environment has been designed and implemented for technical writers. This environment, called Concordia, is an extension of Genera, the software development environment provided on Symbolics computers. It applies object-oriented techniques to creating, publishing, and maintaining complex documentation. The discussion covers the goals and design of Concordia, creating and editing documents, viewing and reviewing documents, and production. The Concordia approach is evaluated.<> 相似文献

The dealing-room study is one of many studies that have used video to support requirements elicitation and the general design process. A growing body of experience with video-based ethnographies supports technology development in various domains, including air traffic and other control rooms, healthcare, public settings such as museums, and more experimental technologies, including media spaces and ubiquitous computing. 相似文献
