  Fiala, D.: Bibliometric analysis of CiteSeer data for countries.
  In: Information processing and management. 48(2012) no.2, S.242-253.
  
  Abstract: This article describes the results of our analysis of the data from the CiteSeer digital library. First, we examined the data from the point of view of source top-level Internet domains from which the data were collected. Second, we measured country shares in publications indexed by CiteSeer and compared them to those based on mainstream bibliographic data from the Web of Science and Scopus. And third, we concentrated on analyzing publications and their citations aggregated by countries. This way, we generated rankings of the most influential countries in computer science using several non-recursive as well as recursive methods such as citation counts or PageRank. We conclude that even if East Asian countries are underrepresented in CiteSeer, its data may well be used along with other conventional bibliographic databases for comparing the computer science research productivity and performance of countries.

  Abstract: Dieser Beitrag beschäftigt sich primär mit der technischen Funktionsweise von wissenschaftlichen Suchmaschinen. Nach einer kurzen Einführung über das Angebot von wissenschaftlichen Informationen im Internet erfolgt zunächst eine Definition des Begriffs der wissenschaftlichen Suchmaschine. Darauf aufbauend wird dargestellt, welche Stärken und Schwächen wissenschaftliche Suchmaschinen gegenwärtig aufweisen und für welche Einsatzzwecke sie besonders geeignet sind. Anschließend wird die technische Funktionsweise dieser Suchdienste beschrieben, wobei insbesondere auf jene Aspekte eingegangen wird, in denen sich wissenschaftliche von allgemeinen Suchmaschinen unterscheiden. Neben dem internen Aufbau der Suchmaschinen wird in diesem Zusammenhang auch auf die von wissenschaftlichen Suchmaschinen angebotenen Suchoperatoren und Interaktionsmechanismen eingegangen. Wichtig sind in diesem Kontext insbesondere auch der Zugriff und die Referenzierung von Dokumenten. Abschließend wird anhand einer von den Autoren erarbeiteten Kriterienliste ein vergleichender Überblick über am Markt existierende, wissenschaftliche Suchmaschinen gegeben.

  Farooq, U. ; Ganoe, C.H. ; Carroll, J.M. ; Councill, I.G. ; Giles, C.L.: Design and evaluation of awareness mechanisms in CiteSeer.
  In: Information processing and management. 44(2008) no.2, S.596-612.
  
  Abstract: Awareness has been extensively studied in human computer interaction (HCI) and computer supported cooperative work (CSCW). The success of many collaborative systems hinges on effectively supporting awareness of different collaborators, their actions, and the process of creating shared work products. As digital libraries are increasingly becoming more than just repositories for information search and retrieval - essentially fostering collaboration among its community of users - awareness remains an unexplored research area in this domain. We are investigating awareness mechanisms in CiteSeer, a scholarly digital library for the computer and information science domain. CiteSeer users can be notified of new publication events (e.g., publication of a paper that cites one of their papers) using feeds as notification systems. We present three cumulative user studies - requirements elicitation, prototype evaluation, and naturalistic study - in the context of supporting CiteSeer feeds. Our results indicate that users prefer feeds that place target items in query-relevant contexts, and that preferred context varies with type of publication event. We found that users integrated feeds as part of their broader, everyday activities and used them as planning tools to collaborate with others.

  Zhao, D. ; Strotmann, A.: Can citation analysis of Web publications better detect research fronts?.
  In: Journal of the American Society for Information Science and Technology. 58(2007) no.9, S.1285-1302.
  
  Abstract: We present evidence that in some research fields, research published in journals and reported on the Web may collectively represent different evolutionary stages of the field, with journals lagging a few years behind the Web on average, and that a "two-tier" scholarly communication system may therefore be evolving. We conclude that in such fields, (a) for detecting current research fronts, author co-citation analyses (ACA) using articles published on the Web as a data source can outperform traditional ACAs using articles published in journals as data, and that (b) as a result, it is important to use multiple data sources in citation analysis studies of scholarly communication for a complete picture of communication patterns. Our evidence stems from comparing the respective intellectual structures of the XML research field, a subfield of computer science, as revealed from three sets of ACA covering two time periods: (a) from the field's beginnings in 1996 to 2001, and (b) from 2001 to 2006. For the first time period, we analyze research articles both from journals as indexed by the Science Citation Index (SCI) and from the Web as indexed by CiteSeer. We follow up by an ACA of SCI data for the second time period. We find that most trends in the evolution of this field from the first to the second time period that we find when comparing ACA results from the SCI between the two time periods already were apparent in the ACA results from CiteSeer during the first time period.

  Kanaeva, Z.: Ranking: Google und CiteSeer.
  In: Information - Wissenschaft und Praxis. 56(2005) H.2, S.87-92.
  
  Abstract: Im Rahmen des klassischen Information Retrieval wurden verschiedene Verfahren für das Ranking sowie die Suche in einer homogenen strukturlosen Dokumentenmenge entwickelt. Die Erfolge der Suchmaschine Google haben gezeigt dass die Suche in einer zwar inhomogenen aber zusammenhängenden Dokumentenmenge wie dem Internet unter Berücksichtigung der Dokumentenverbindungen (Links) sehr effektiv sein kann. Unter den von der Suchmaschine Google realisierten Konzepten ist ein Verfahren zum Ranking von Suchergebnissen (PageRank), das in diesem Artikel kurz erklärt wird. Darüber hinaus wird auf die Konzepte eines Systems namens CiteSeer eingegangen, welches automatisch bibliographische Angaben indexiert (engl. Autonomous Citation Indexing, ACI). Letzteres erzeugt aus einer Menge von nicht vernetzten wissenschaftlichen Dokumenten eine zusammenhängende Dokumentenmenge und ermöglicht den Einsatz von Banking-Verfahren, die auf den von Google genutzten Verfahren basieren.

  Feitelson, D.G. ; Yovel, U.: Predictive ranking of computer scientists using CiteSeer data.
  In: Journal of documentation. 60(2004) no.1, S.44-61.
  
  Abstract: The increasing availability of digital libraries with cross-citation data on the Internet enables new studies in bibliometrics. The paper focuses on the list of 10.000 top-cited authors in computer science available as part of CiteSeer. Using data from several consecutive lists a model of how authors accrue citations with time is constructed. By comparing the rate at which individual authors accrue citations with the average rate, predictions are made of how their ranking in the list will change in the future.

  New Web Citation Index.
  In: Online Mitteilungen. 2004, Nr.78, S.39 [=Mitteilungen VÖB 57(2004) H.1].
  
  Abstract: Philadelphia, PA USA-London UK-Princeton, NJ February, 25, 2004 - Today, Thomson ISI and NEC Laboratories America (NEC) announced their collaboration to create a comprehensive, multidisciplinary citation index for Web-based scholarly resources. The new Web Citation Index(tm) will combine a suite of technologies developed by NEC, including "autonomous citation indexing" tools from NEC's CiteSeer environment, with the capabilities underlying ISI Web of KnowledgeSM. Thomson ISI editors will carefully monitor the quality of this new resource to ensure all indexed material meets the Thomson ISI high-quality standards. During 2004, Thomson ISI and NEC will operate a pilot of the new resource to receive feedback from the scientific and scholarly community. Full access to the index is projected for early 2005. When fully operational, the new resource will be a unique content collection within ISI Web of Knowledge. It will complement the Thomson ISI Web of Science(r), and provide researchers with a new gateway to discovery 4/3 using citation relationships among Web-based documents, such as pre-prints, proceedings, and "open access" research publications.
