- 748 sameAs 748.
- 748 abstract "This paper presents the architecture and the preliminary evaluation of a request routing DNS server that decouples server selection from the rest of DNS functionality. Our DNS server, which we refer to as MyXDNS, exposes well-defined APIs for uploading an externally computed server selection policy and for interacting with an external network proximity service. With MyXDNS, researchers can explore their own network proximity metrics and request routing algorithms without having to worry about DNS internals. Furthermore, MyXDNS is based on open-source MyDNS and is available to public. Stress-testing of MyXDNS indicated that it achieves its flexibility at an acceptable cost: a single MyXDNS running on a low-level server can process 3000 req/sec with sub-millisecond response even in the presence of continuous updates to server selection policy.".

- 752 abstract "The demand of browsing information from general Web pages using a mobile phone is increasing. However, since the majority of Web pages on the Internet are optimized for browsing from PCs, it is difficult for mobile phone users to obtain sufficient information from the Web. Therefore, a method to reconstruct PC-optimized Web pages for mobile phone users is essential. An example approach is to segment the Web page based on its structure, and utilize the hierarchy of the content element to regenerate a page suitable for mobile phone browsing. In our previous work, we have examined a robust automatic Web page segmentation scheme which uses the distance between content elements based on the relative HTML tag hierarchy, i.e., the number and depth of HTML tags in Web pages. However, this scheme has a problem that the content-distance based on the order of HTML tags does not always correspond to the intuitional distance between content elements on the actual layout of a Web page. In this paper, we propose a hybrid segmentation method which segments Web pages based on both the content-distance calculated by the previous scheme, and a novel approach which utilizes Web page layout information. Experiments conducted to evaluate the accuracy of Web page segmentation results prove that the proposed method can segment Web pages more accurately than conventional methods. Furthermore, implementation and evaluation of our system on the mobile phone prove that our method can realize superior usability compared to commercial Web browsers.".

- 753 abstract "We address the problem of measuring relevance neutral search quality metrics, like corpus size, index freshness, and density of duplicates in the index. The recently proposed estimators for such metrics [Bar-Yossef and Gurevich, WWW2006][Broder et al, CIKM 2006] suffer from significant bias and/or poor performance, due to inaccurate approximation of the so called ``document degrees''.<br /><br /> We present two new estimators that are able to overcome the bias introduced by approximate degrees. Our estimators are based on a careful implementation of an approximate importance sampling procedure. Comprehensive theoretical and empirical analysis of the estimators demonstrates that they have essentially no bias even in situations where document degrees are poorly approximated.<br /><br /> Building on an idea from [Broder et al, CIKM 2006], we discuss Rao-Blackwellization as a generic method for reducing variance in search engine estimators. We show that Rao-Blackwellizing our estimators results in significant performance improvements, while not compromising quality.".
