A Web crawler is a module of a search engine that fetches data from various servers. Web crawlers are an essential component to search engines; running a web crawler is a challenging task. It is a time-taking process to gather data from various sources around the world. Such a single process faces limitations on the processing power of a single machine and one network connection. This module de...

We propose reducing errors in text entry by combining speech and gesture keyboard input. We describe a merge model that combines recognition results in an asynchronous and flexible manner. We collected speech and gesture data of users entering both short email sentences and web search queries. By merging recognition results from both modalities, word error rate was reduced by 53% relative for e...

Nowadays, Web encyclopedias suffer from a high bounce rate. Typically, users come to an encyclopaedia from a search engine and upon reading the first page on the site they leave it immediately thereafter. To tackle this problem in systems such as Web shops additional browsing tools for easy finding of related content are provided. In this paper we present a tool that links related content in an...

Despite of the popularity of global search engines, people still suffer from low accuracy of site search. The primary reason lies in the difference of link structures and data scale between global Web and website, which leads to failures of traditional re-ranking methods such as HITS, PageRank and DirectHit. This paper proposes a novel re-ranking method based on user logs within websites. With ...

The dimer method is a Hessian-free algorithm for computing saddle points. We augment the method with a linesearch mechanism for automatic step size selection as well as preconditioning capabilities. We prove local linear convergence. A series of numerical tests demonstrate significant performance gains.

the increasing prevalence rate of breast cancer among asian-american women shows the more significant role of lifestyle factors in etiology than genetic factors. the search engine pubmed was used for searching related paper by “breast cancer”, “soy”, “isoflavones”, “phytoestrogen” as the key words. we selected papers which published during 1990 to 2012. various experimental studies reported the...

Prominent theories of attention claim that visual search is guided through attentional templates stored in working memory. Recently, the contralateral delay activity (CDA), an electrophysiological index of working memory storage, has been found to rapidly decrease when participants repeatedly search for the same target, suggesting that, with learning, the template moves out of working memory. H...

The World Wide Web is an enormous collection of information, but to fully exploit its power, users must be able to find the information they want from that space. Without a doubt, the de facto standard for information discovery on the Web is the search engine. Given the amazing rate of growth of the amount of information available on the Web, search engines are becoming an essential part of the...

This paper introduces a new hybrid hill-climbing algorithm (HHC) for solving the Economic Dispatch (ED) problem. This algorithm solves the ED problems with a systematic search structure with a global search. It improves the results obtained from an evolutionary algorithm with local search and converges to the best possible solution that grabs the accuracy of the problem. The most important goal...
