What does the internet know about the development of software?

Software is dynamic, and is subject to continuous development. In fact, the boundaries between different states and versions of a software program in the course of its development are often blurred. It is difficult to grasp the state of a software program; it can only, if at all, be described by its version number. Not only do software programs develop, the way in which they are presented on the internet – whether on the official website or in discussions and descriptions on external websites – is also frequently subject to development. Web archives enable users to track the development of a software program. In the context of the Specialised Information Service Mathematics, a web service was developed (the Tempas TimePortal) that links the temporal development of software websites to the actual software program. In the database for relevant software in mathematics swMATH, the integration of the TimePortal now enables users, on the basis of the website, to track the status of the software program at the time when a scientific article referring to the software was published.

L3S and Alexandria congratulate the Internet Archive for winning the Webby Lifetime Achievements Award

The L3S Research Center and the Alexandria project congratulate the Internet Archive for winning the Webby Lifetime Achievements Award 2017 on the evening of May 15, 2017 in New York. The Webby Awards – hailed by the New York Times as “one of the Internet’s highest honors” – lauded the Internet Archive for being “the web’s most knowledgeable historian.”

Three of IA veteran staff members, Tracey Jaquith, TV Archive Architect, Internet Archive founder and Digital Librarian, Brewster Kahle, and Alexis Rossi, Director of Media and Access, accepted the award. Kahle delivered the five-word acceptance speech with panache: “Universal Access to All Knowledge.”

“The Internet Archive…is building a home for Universal Access to All Knowledge, open to everyone, everywhere, to use as they like. Open to all societies of the future that care to build on our triumphs and learn from our mistakes.”

Alexandria at JCDL 2017

The 2017 ACM/IEEE-CS Joint Conference on Digital Libraries will be held in Toronto (Ontario, Canada) on June 19-23. L3S will be again present in this annual venue with one full research paper and one poster, both conducted in the context of the ALEXANDRIA project. The works will be presented by Dr. Pavlos Fafalios and are co-authored by Prof. Wolfgang Nejdl.
The research paper, entitled “Building and Querying Semantic Layers for Web Archives” and authored by P. Fafalios, H. Holzmann, V. Kasturia, and W. Nejdl, introduces an RDF/S model and a distributed framework for building semantic layers that describe semantic information about the contents of web archives. A semantic layer allows describing metadata information about the archived documents, annotating them with useful semantic information (like entities, concepts and events), and publishing all this data on the Web as Linked Data. Such structured repositories offer advanced query and integration capabilities and make web archives directly exploitable by other systems and tools. A preprint of the article is available in this link.
In the same context, the poster paper (entitled “Towards a Ranking Model for Semantic Layers over Digital Archives” and authored by P. Fafalios, V. Kasturia, and W. Nejdl) focuses on the problem of ranking archived documents returned by structured (SPARQL) queries over semantic layers. The poster discusses the motivation for this work, formalizes the problem, and proposes a baseline model that considers and combines the following three aspects: i) the relativeness of documents to entities, ii) the timeliness of documents, and iii) the relations among the entities. A preprint is available in this link.
Following last year’s nomination for the ArchiveSpark <https://arxiv.org/pdf/1702.01015.pdf> paper, this is the second-in-a-row best paper nomination at JCDL for the Alexandria team.

CIKM 2016 with Alexandria contributions

The 2016 edition of the Conference on Information and Knowledge Management (CIKM) took place on October 24-29, 2016 in Indianapolis, IN, USA. CIKM is major forum for presentation and discussion of research on information and knowledge management. The Alexandria team of L3S was involved with two papers by Besnik Fetahu et al. on finding news citations for Wikipedia, and Jaspreet Singh et al. on a human-in-the-loop retrieval method for discovering entities:

Alexandria at JCDL 2016

Helge Holzmann presenting ArchiveSparkOn June 16-23 this year’s ACM/IEEE-CS Joint Conference on Digital Libraries (JCDL 2016) took place in Newark, New Jersey. JCDL is a major international forum focusing on digital libraries and associated technical, practical, and social issues. The L3S was involved in this important event with two research paper presentations by Helge Holzmann, showing results of their research in the area of Web archiving as part of the EU project Alexandria (an ERC Advanced Grant by Prof. Wolfgang Nejdl). The first paper was co-authored by Prof. Wolfgang Nejdl as well as Dr. Avishek Anand: “The Dawn of Today’s Popular Domains: A Study of the Archived German Web over 18 Years”.

The second paper, again co-authored by Dr. Avishek Anand, has been joint work with the Internet Archive (archive.org) and showed their successful work on the Web archive data processing framework ArchiveSpark, developed by Helge Holzmann (L3S) and Vinay Goel (Internet Archive): “ArchiveSpark: Efficient Web Archive Access, Extraction and Derivation”. The paper on ArchiveSpark was nominated for the best paper award of the conference, which shows the need of this tool as well as the growing importance of Web archives in the Digital Libraries community.

ArchiveSpark is open-source and freely available under https://github.com/helgeho/ArchiveSpark.
