January 13, 2011 Internet pages are like stars in the sky: They are uncountable many, and every day new appear. They bring new texts, information, and pictures into existence, some of which only exist in the Internet. But who is to decide which pages are worth to preserve? Libraries and archives are currently rather helpless to deal with such gigantic amounts of data. With the current state of technology, it is not feasible to review and select all material for archiving. But this is about to change. Two European projects will help to preserve the digital cultural heritage of the World Wide Web. The “Archive Community Memories” project focuses on automatic selection of web-content that is socially relevant. A new archiving method will not specifically search for topics or events in the Web and rate their importance. To achieve this not only Web pages of organizations or companies are evaluated, but also private content like publicly accessible blogs or social networks like Facebook. Social networks can be very helpful in discovering important Web pages, as users will suggest such pages to their friends. By harnessing such and other information, the project will help to optimize and to speed-up the reviewing process of national libraries or archives. The total size of the EU project is eight million Euro. L3S Research Center at Leibniz University Hannover receives one million euro, and leads the scientific management. The overall management is led by researchers from University of Sheffield. There are also several other partners involved in the project, like Yahoo!, Südwestrundfunk, and Deutsche Welle. The project is a follow-up of “Living Web Archives”, in which researchers from L3S Research Center and other European partners have been working in the past years. The goal was to improve the quality of Web archives, especially regarding multi-media content, spam detection, as well as enabling the use of the archive for future generations.

Erdélyi, A. Garzó, and A. A. Benczúr has been accepted for presentation in Joint Web Quality 2011 in conjunction with the WWW2011, Hyderabad, India, ACM Press 2011. In this paper we investigate how much various classes of Web spam features, some requiring very high computational effort, add to the classification accuracy. We realize that advances in machine learning, an area that has received less attention in the adversarial IR community, yields more improvement than new features and result in low cost yet accurate spam filters.

Niklas, G. Zenz, and T. Risse has been submitted to the Journal of Computational Linguistics. Word sense discrimination is the first, important step towards automatic detection of language evolution within large, historic document collections. By comparing the found word senses over time, we can reveal and use important information that will improve understanding and accessibility of a digital archive. Algorithms for word sense discrimination have been developed while keeping today’s language in mind and have thus been evaluated on well selected, modern datasets. The quality of the word senses found in the discrimination step has a large impact on the detection of language evolution. Therefore, as a first step, we verify that word sense discrimination can successfully be applied to digitized historic documents and that the results correctly correspond to word senses. Because accessibility of digitized historic collections is influenced also by the quality of the optical character recognition (OCR), as a second step we investigate the effects of OCR errors on word sense discrimination results. All evaluations in this paper are performed on The Times Archive, a collection of newspaper articles from 1785 - 1985.
