Using Transaction Logs to Better Understand User Search Session Patterns in an Image-based Digital Library

Using Transaction Logs to Better Understand User Search Session Patterns in an Image-based Digital Library*

Server transaction logs containing complete click-through data from a digital library of primarily image-based documents were analyzed to better understand user search session behavior. One month of data was analyzed using descriptive statistics and network analysis methods. The findings reveal iterative search behaviors centered on result views and evaluation and topical areas of focus for the...

Using SVG for an User-Interface to a Digital Library

Interfaces for users on the web are usually created using standard HTML-technologies. Although dynamic textbased features are widely available on the web (e.g. by using DHTML) there are still some limitations in the user experience when using dynamic graphical elements. In this article we focus on a GUI-prototype using Scalable Vector Graphics (SVG) as an interface to an existing Digital Librar...

Enhanced Image Search by Deducing User Search Goals using Query Logs

In web search applications, queries are submitted to search engines to represent the information needs of users. However, sometimes queries may not exactly represent users specific information needs since many ambiguous queries may cover a broad topic and different users may want to get information on different aspects when they submit the same query. To define user search goals as the informat...

Detecting session boundaries from Web user logs

Detecting session boundaries on the Web is important for several reasons. Firstly, it is important to establish a common context for various statistics relating to user sessions and frequency of user activities. More specifically, it is important to detect some boundaries in order to group related information together for other applications, such as learning techniques for adaptive search engin...
