Current supervised approaches to e-EI suffer both from high initial and high maintenance costs, due to the need to manually label examples to train and update a classifier for detecting disease reporting events in dynamic information sources, such as blogs.\u0000 In this paper, we propose a new method for the supervised detection of disease reporting events. We tackle the burden of manually labelling data and address the problems associated with building a supervised learner to classify frequently evolving, and variable blog content. We automatically classify outbreak reports to train a supervised learner, and the knowledge acquired from the learning process is then transferred to the task of classifying blogs. Our experiments show that with the automatic classification of training data, and the transfer approach, we achieve an overall precision of 92% and an accuracy of 78.20%.","PeriodicalId":91270,"journal":{"name":"HT ... : the proceedings of the ...

The most common role of tags is descriptive. However, tags are being used for other purposes such as to indicate some actions to be conducted on the resource (e.g. 'toread'). This work focuses on 'prescriptive tags' that have associated some implicit behaviour in the user's mind. So far, little support is given for the automation of this \"implicit behaviour\", more to the point, if this behaviour is outside the tagging site. This paper introduces the notion of 'reactive tags' as a means for tagging to impact sites other than the tagging site itself. The operational semantics of reactive tags is defined through event-condition-action rules. Events are the action of tagging. Conditions check for additional data. Finally, rule's actions might impact someone else's account in a different website. The specification of this behaviour semantics is hidden through a graphical interface that permits users with no programming background to easily associate 'reactions' to the act of tagging. A working system, TABASCO, is presented as proof of concept.","PeriodicalId":91270,"journal":{"name":"HT ... : the proceedings of the ... ACM Conference on Hypertext and Social Media.

It is hence interesting trying to understand how they do it. While most of the scholar attention focused on article pages, a less investigated share of activities happen on user talk pages, Wikipedia pages where a message can be left for the specific user. This public conversations can be studied from a Social Network Analysis perspective in order to highlight the structure of the \"talk\" network. In this paper we focus on this preliminary extraction step by proposing different algorithms. We then empirically validate the differences in the networks they generate on the Venetian Wikipedia with the real network of conversations extracted manually by coding every message left on all user talk pages. The comparisons show that both the algorithms and the manual process contain inaccuracies that are intrinsic in the freedom and unpredictability of Wikipedia syntax and practices. Nevertheless, a precise description of the involved issues allows to make informed decisions and to base empirical findings on reproducible evidence. Our goal is to lay the foundation for a solid computational sociology of wikis. For this reason we release the scripts encoding our algorithms as open source and also some datasets extracted out of Wikipedia conversations, in order to let other researchers replicate and improve our initial effort.","PeriodicalId":91270,"journal":{"name":"HT ... : the proceedings of the ...

Even though all common web browsers were equipped with a history list and bookmarks early enough to facilitate this need, most users typically use search engines to refind information. However, both bookmarks and search based tools have significant limitations that impact their usability: the former are known to be hard to manage over the course of time, whereas the latter require the user to recall a specific combination of keywords or context. Most importantly, though, both are particularly inappropriate in cases where a piece of information is contained within an unstructured web page. In this paper, we present in-context annotation as a more efficient alternative to these methodologies. To verify this claim, we conducted a study in which we compare the performance of experienced users in all three approaches while revisiting specific pieces of information in the web after a long period of time. The outcomes suggest that in-context annotation clearly outperforms both traditional strategies.","PeriodicalId":91270,"journal":{"name":"HT ... : the proceedings of the ...
