IWAW Proceedings online
IWAW09 took take place the 30th of September and 1st of October 2009, in conjunction with ECDL in Corfu (Greece). The proceedings are now available online.
Around 40 participants attended IWAW2009, which took place on Sep. 30 / Oct. 1 2009, in conjunction with ECDL in Corfu (Greece). The workshop provided a comprehensive overview on active research and practice on the preservation of the Web. This year’s workshop also addressed several new approaches and research (from virtual worlds preservation to temporal dimension of Web Archives) as well as practical issues addressed by Archiving institutions, specifically with respect to managing the storage of large volumes of digital material. In this context, a special Session was devoted to the WARC storage format, which has been accepted as a new ISO standard (ISO 28500:2009), as well as emerging tool support to handle these container objects. In general, scalability issues and managing large-volume crawls were topics of intensive discussions, based on the increasing body of experience available in numerous institutions by now, running a series of Web archiving activities in a range of different configurations.
Talk about “Turning pure Web Page Storages into Living Web Archives” at Cultural Heritage on line
The LiWA applications and its R&D challenges will be presented at the Conference “Cultural Heritage on line Empowering users: an active role for user communities” at Florence, Italy on the 15th and 16th of December, 2009
Web content plays an increasingly important role in the knowledge-based society, and the preservation and long-term accessibility of Web history has high value (e.g., for scholarly studies, market analyses, intellectual property disputes, etc.). There is strongly growing interest in its preservation by libraries and archival organizations as well as emerging industrial services. Web content characteristics (high dynamics, volatility, contributor and format variety) make adequate Web archiving a challenge.
LiWA will look beyond the pure “freezing” of Web content snapshots for a long time, transforming pure snapshot storage into a “Living” Web Archive. In order to create Living Web Archives, the LiWA project will address R&D challenges in the three areas: Archive Fidelity, Archive coherence and Archive interpretability. The results of the project will be demonstrated within two application scenarios namely “Streaming Archive” and “Social Web Archive”. The Streaming Archive application will showcase the building of an audio-visual Web archive and how audio and video broadcast related web information can be preserved. The Social Web application will demonstrate how web archives can capture the dynamics and the different types of user interaction of the social web.

Bridging the Terminology Gap in Web Archive Search
A paper on dealing with terminology evolution in web archives has been accepted in the 12th International Workshop on the Web and Databases (WebDB 2009)
The paper entitled ’Bridging the Terminology Gap in Web Archive Search’ by Klaus Berberich, Srikanta Bedathur, Mauro Sozio, and Gerhard Weikum has been accepted in the 12th International Workshop on the Web and Databases (WebDB 2009). The paper proposes a method to find query reformulations that paraphrase users’ information needs using past terminology. Such query reformulations are key to retrieving old but highly relevant documents in web archives that were written using now outdated terminology. Klaus Berberich will present the paper on June 28th, 2009 at WebDB 2009, which is held in conjunction with SIGMOD 2009 in Providence (Rhode Island, USA).
SHARC: Framework for Quality-Conscious Web Archiving
A paper on quality-conscious web archiving has been accepted in the 35th International Conference on Very Large Data Bases (VLDB 2009)
The paper on quality-conscious web archiving by Dimitar Denev, Arturas Mazeika, Marc Spaniol, and Gerhard Weikum has been accepted for presentation to the 35th International Conference on Very Large Data Bases (VLDB 2009). The conference takes place on 24-28 August in Lyon, France. The paper presents the SHARC framework for assessing the data quality in Web archives and for tuning capturing strategies towards better quality with given resources. The paper defines quality measures, characterise their properties, and derives a suite of quality-conscious scheduling strategies for archive crawling.
LiWA Poster at the CHORUS Conference in Brussels
Nina Tahmasebi (L3S) will present a poster on the LiWA project in the CHORUS conference in Brussels (Belgium) on May 26-27, 2009. The poster will present the overall goals of LiWA and in particular semantic evolution.
Talk “Terminology Evolution in Web Archiving” at Vienna
Dr. Thomas Risse (L3S) will give a talk on “Terminology Evolution in Web Archiving” at Seminarraum, Institut für Knowledge und Business Engineering, in Rathausstrasse 19/9, A-1010 Wien; on April 30, 2009.
Due to the central role that the World Wide Web plays in nearly all areas
of today’s life, adequate Web archiving has become a cultural necessity in
preserving knowledge. The next generation web archiving technologies will
overcome limitations in content capture, preservation, analysis and
enrichment. One important aspect is the archive interpretability. The
correspondence between the terminology used for querying and the one used
in content objects to be retrieved is a crucial prerequisite for effective
content access based on retrieval technology. However, as terminology is
evolving over time, a growing gap opens up between older documents in
(long-term) archives and the active language used for querying such
archives. Thus, technologies for detecting and systematically handling
terminology evolution are required to ensure ``semantic’’ accessibility of
(Web) archive content on the long run. As a starting point for dealing
with terminology evolution present the problem and discusses issues,
approaches and relevant technologies.
Talk “Data Quality in Web Archiving”
A talk on “Data Quality in Web Archiving” will be given at the 3rd Workshop on Information Credibility on the Web (WICOW 2009) in Madrid (Spain) on Monday, April 20.
The paper on “Data Quality in Web Archiving” by Marc Spaniol, Dimitar Denev, Arturas Mazeika, Pierre Senellart and Gerhard Weikum will be presented at the 3rd Workshop on Information Credibility on the Web (WICOW 2009). The Workshop and paper presentation takes places on April 20 at Madrid, Spain and is organized in conjunction with the 18th International World Wide Web Conference (WWW 2009). The paper addresses the problems of capturing a large Web site that may span hours or even days, which increases the risk that contents collected so far are incoherent with the parts that are still to be crawled. The paper introduces a model for identifying coherent sections of an archive and, thus, measuring the data quality in Web archiving. Additionally, a crawling strategy is introduced that aims to ensure archive coherence by minimizing the diffusion of Web site captures.

Abstract
Due to the central role that the World Wide Web plays in nearly all areas of today’s life, adequate Web archiving has become a cultural necessity in preserving knowledge. A first generation of Web archiving technology has been built by pioneers in the domain based on existing search technology. The next generation web archiving technologies will overcome limitations in content capture, preservation, analysis and enrichment. It is the goal of the LiWA project (Living Web Archives, IST FP7 216267) to turn Web archives from pure Web page storages into “living Web archives”. Such living archives, will be capable of: handling a variety of content types; dealing with evolution as well as long-term archive interpretability.
One important aspect is the archive interpretability. The correspondence between the terminology used for querying and the one used in content objects to be retrieved is a crucial prerequisite for effective content access based on retrieval technology. However, as terminology is evolving over time, a growing gap opens up between older documents in (long-term) archives and the active language used for querying such archives. Thus, technologies for detecting and systematically handling terminology evolution are required to ensure ``semantic’’ accessibility of (Web) archive content on the long run.
Within this talk we give an overview about the LiWA project and present in more detail the problem of terminology evolution by giving a more formal problem statement and discuss issues, first ideas and relevant technologies.
Living Web Archives Announcement
Press Release
February 18, 2008
The Living Web Archives project will carry Web archiving beyond the current approach, characterized by static snapshots, to one that fully accounts for the dynamics and interrelations of Web content. Through an ambitious plan of research, the project aims to improve archive fidelity, coherence, and interpretability.
The three-year project is funded by the European Union through the Seventh Research Framework Programme.
The project kick-off meeting was held earlier this month in Hannover, Germany.
The result of LiWA’s work will be a set of next generation Web archiving methods and tools making possible the creation and long-term usability of high-quality Web archives. Aspects of the project’s research will focus on improving Web capture fidelity by providing for the capture of the hidden Web and all types of content, including content that is currently difficult to gather, and by filtering out unwanted content through spam and trap detection.
Other aspects of the project will address the temporal incoherence inherent in current Web capture methods and tools. The research will also address the rapid semantic and technological evolution of the Web in order to promote the long-term viability of Web archives.
LiWA research will lead to scalable technologies, applicable to the Web archiving goals in institutions with varying collection policies.
