Abstract

Twitter, Facebook, and other related systems that we call social awareness streams are rapidly changing the information and communication dynamics of our society. These systems, where hundreds of millions of users share short messages in real time, expose the aggregate interests and attention of global and local communities. In particular, emerging temporal trends in these systems, especially those related to a single geographic area, are a significant and revealing source of information for, and about, a local community. This study makes two essential contributions for interpreting emerging temporal trends in these information systems. First, based on a large dataset of Twitter messages from one geographic area, we develop a taxonomy of the trends present in the data. Second, we identify important dimensions according to which trends can be categorized, as well as the key distinguishing features of trends that can be derived from their associated messages. We quantitatively examine the computed features for different categories of trends, and establish that significant differences can be detected across categories. Our study advances the understanding of trends on Twitter and other social awareness streams, which will enable powerful applications and activities, including user-driven real-time information services for local communities.

"Der Musiker und Produzent Dieter Bohlen wurde als Dieter Günther Bohlen am 7. Februar 1954 in Oldenburg geboren. Die Ruine Steinschloss ist die höchstgelegene Burg-Ruine in der österreichischen Steiermark. Dieses und anderes Wissen bietet die Online-Enzyklopädie www.wikipedia.de. Das besondere daran: Die mehr als 100.000 deutschsprachigen Artikel stammen nicht aus einer Lexikon-Redaktion. Denn jeder kann bei Wikipedia mitarbeiten. Tausende Autoren schreiben und recherchieren an der Wissensdatenbank - ohne Lohn und mit dem Ziel, irgendwann einmal mit dem Brockhaus konkurrieren zu können. Dabei sind die Texte mit Quellenangabe frei verfügbar. Knapp 500 Artikel kommen nach Angaben des Projektsprechers Arne Klempert täglich neu hinzu. "Die Qualität ist dabei sehr unterschiedlich, sagt Klempert. Manchmal handelt es sich um Einzeiler, die gerade noch so als Artikel durchgehen." Andererseits gebe es aber auch eine Reihe exzellenter Beiträge. - Jeder kann jeden Text verbessern - Die Wikipedianer, so nennen sich die Aktiven bei Wikipedia selbst, verfahren mit den Texten anarchisch: Jeder kann jeden Text verbessern, Passagen hinzufügen oder löschen. Da ist Vandalismus Tür und Tor geöffnet, möchte man meinen. Doch die Störer verlieren bei der Online-Enzyklopädie schnell die Lust, sagt Klempert. Alle Versionen eines Artikels sind jederzeit abrufbar, nichts geht für immer verloren. Rund 4000 registrierte und ungezählte nicht-registrierte Autoren hüten den Wissensschatz Wikipedia und stellen ihre eigenen Kenntnisse zur Verfügung, um das Lexikon weiterzuentwickeln. Viele haben Spaß daran, ihr Wissen zu teilen und durch die Verbesserungen der anderen Autoren lernt man selbst wieder etwas dazu", beschreibt Klempert das Motiv, ein Wikipedianer zu sein. Die Idee zu Wikipedia hatte der US-Amerikaner Jimmy Wales. Im Januar 2001 startete zunächst eine englischsprachige Version der Online-Enzyklopädie, bereits im Mai des gleichen Jahres entstand die deutsche Ausgabe. Unterdessen List die Online-Enzyklopädie in rund 80 Sprachen verfügbar, darunter Esperanto und Plattdeutsch. Die englische Version ist derzeit die größte, gefolgt von der deutschen Wikipedia. Die Serverfarm in Florida wird von Wales' Stiftung Wikimedia getragen. Der Brockhaus-Verlag, der im kommenden Jahr 200 Jahre alt wird, sieht die Konkurrenz aus dem Internet gelassen. Brockhaus-Sprecher Klaus Holoch glaubt nicht, dass Wikipedia einmal den Brockhaus ersetzen kann. "Die Brockhaus-Enzyklopädie bietet geprüftes Wissen, auf das man sich hundertprozentig verlassen kann.""

Abstract

Purpose - The purpose of this paper is to engage in a systematic analysis of academic research that relies on the collection and use of Twitter data, creating topology of Twitter research that details the disciplines and methods of analysis, amount of tweets and users under analysis, the methods used to collect Twitter data, and accounts of ethical considerations related to these projects. Design/methodology/approach - Content analysis of 382 academic publications from 2006 to 2012 that used Twitter as their primary platform for data collection and analysis. Findings - The analysis of over 380 scholarly publications utilizing Twitter data reveals noteworthy trends related to the growth of Twitter-based research overall, the disciplines engaged in such research, the methods of acquiring Twitter data for analysis, and emerging ethical considerations of such research. Research limitations/implications - The findings provide a benchmark analysis that must be updated with the continued growth of Twitter-based research. Originality/value - The research is the first full-text systematic analysis of Twitter-based research projects, focussing on the growth in discipline and methods as well as its ethical implications. It is of value for the broader research community currently engaged in social media-based research, and will prompt reflexive evaluation of what research is occurring, how it is occurring, what is being done with Twitter data, and how researchers are addressing the ethics of Twitter-based research.

Abstract

IODyone is an Internet client program that allows one to retriev information from servers by dynamically combining information objects. Information objects are abstract representations of bibliographic data, typically titles (or title keywords), author names, subject and classification identifiers, and full-text search terms

Abstract

This article explores the reasons why librarians should be at the heart of Internet site development. There are two distinct ways in which librarians can most effectively contribute to this medium. The first is by getting involved in information architecture. This new discipline requires skills such as expertise in search techniques and navigational logic, and generally involves the librarian working closely with graphic designers to create a firm foundation for the site. The second area is the role librarians can play in the structuring of the data which drives the site (data management).
