- KonferenzbeitragFacetBrowse: Ein facettenbasierter Dateibrowser für das kooperative Dokumentenmanagement(Mensch & Computer 2009: Grenzenlos frei!?, 2009) Franken, Sebastian; Prinz, WolfgangDie traditionelle, hierarchische Organisation von virtuellen Objekten stößt gerade in kollaborativen Arbeitsumgebungen schnell an ihre Grenzen, da sie die Priorisierung von Organisationskriterien inhärent fordert, was die Benutzbarkeit von hierarchisch organisierten Strukturen schmälert. Facettenbasierte Organisationsformen können hier Abhilfe schaffen, in dem sie Benutzern die Möglichkeit geben, virtuelle Objekte nach ihren eigenen Kriterien zu organisieren. In diesem Beitrag wird FacetBrowse vorgestellt, ein System, das Facetten auf virtuelle Objekte des Groupware-Systems BSCW (Basic Support for Cooperative Work) anwendet. Wir beschreiben die Anforderungen, Systemkonzept und Implementierung sowie seine iterative Entwicklung und Evaluation.
- KonferenzbeitragFacetBrowse: Ein facettenbasierter Dateibrowser für ein Groupware-System(Workshop-Proceedings der Tagung Mensch & Computer 2009, 2009) Franken, SebastianIn vielen web-basierten, kollaborativen Arbeitsumgebungen werden dem Benutzer virtuelle Objekte im Rahmen einer hierarchischen Organisationsstruktur zur Verfügung gestellt. Doch gerade diese Struktur führt in Mehr-Benutzer Systemen oft zu Problemen, da die Komplexität der in dieser Weise organisierten Arbeitsbereiche ständig steigt und es besonders neuen Benutzern oder Projektteilnehmern schwer fällt, die Organisationsstrukturen zu erfassen. Daher wird in diesem Beitrag das web-basierte System FacetBrowse vorgestellt, das die Objekte der kooperativen Arbeitsumgebung BSCW (Basic Support for Cooperative Work) nach verschiedenen Kriterien dynamisch sortiert. Dadurch wird jedem Benutzer eine individuelle Sicht auf den gemeinsamen Datenbestand ermöglicht.
- KonferenzbeitragSearch Trails as Collaboration Artifacts – Evaluating the UX(Mensch und Computer 2015 – Proceedings, 2015) Franken, Sebastian; Norbisrath, Ulrich; Prinz, WolfgangUsers tend to share search results such as links or excerpts from web pages when performing complex search tasks. We developed a system called SearchTrails that enables sharing of complete search logs in the form of directed graphs, resembling the users’ trails through the Internet. We conducted a study with 29 participants in which we used both written reports and search trails as collaboration artifacts. We researched the value of search trails as artifacts for collaborative search compared to written reports. We did this by evaluating the user experience (UX) with both artifacts. By evaluating a user experience questionnaire (UEQ), we can confirm that search trails can support collaborative search better than written reports containing the essential information of the search trails.
- KonferenzbeitragThe Impact of SearchTrails on the Quality of Collaborative Search(Mensch und Computer 2016 - Tagungsband, 2016) Franken, Sebastian; Norbisrath, Ulrich; Prinz, WolfgangSeveral collaborative search systems build upon real time collaboration during search processes. With SearchTrails, we present a novel way of capturing and exchanging the process of search itself between collaborators. We achieve this by asynchronously exchanging search trails between collaborators and thus overcome the necessity of real-time interaction. In a study with 29 participants, we evaluate the value of search trails as collaboration artifacts to answer the research question whether search trails improve the quality of collaborative search results. We show that this is the case and users can build upon the previous work of co-searchers in a very efficient way by analyzing and extending the search trails as given collaboration artifacts.
- KonferenzbeitragThe Impact of SearchTrails on the Quality of Collaborative Search(i-com: Vol. 16, No. 1, 2017) Franken, Sebastian; Norbisrath, Ulrich; Prinz, WolfgangSeveral collaborative search systems build upon real-time collaboration during search processes. With the software SearchTrails, we present a novel way of capturing and exchanging the search process between collaborators. We achieve this by asynchronously exchanging the newly developed search trails between collaborators and thus overcome the necessity of real-time interaction for search support. In a study with 29 participants, we evaluate the value of search trails as collaboration artifacts to answer the research question whether search trails improve the quality of collaborative search results. We confirm this and show that users can build upon work of co-searchers in a very efficient way by analyzing and extending the given search trails.
- KonferenzbeitragTrail Building During Complex Search Tasks(Mensch & Computer 2014 - Tagungsband, 2014) Franken, Sebastian; Norbisrath, UlrichUsers frequently perform searches that do not only have simple fact retrieval in mind, but aim for more comprehensive results. These complex search tasks need to be distinguished from simple search tasks, where an information need can be fulfilled by simple fact finding. While search engine support for simple search tasks is satisfactory, it lacks in support for complex search tasks, leading to an increasing discontent about the interaction with the search engine of choice. In this paper we address the question, how to give tool support for complex search tasks. We present the logging framework ‘SearchTrails’, which captures the course of user actions of any search task and presents a corresponding graph visualization. We conducted a qualitative user study of SearchTrails and present first promising results.
