TWORPUS - An Easy-to-Use Tool for the Creation of Tailored Twitter Corpora

In this paper we present Tworpus, an easy-to-use tool for the creation of tailored Twitter corpora. Tworpus allows scholars to create corpora without having to know about the Twitter Application Programming Interface (API) and related technical aspects. At the same time our tool complies with Twitter’s ”rules of the road” on how to use tweet data. Corpora may be composed in various sizes and for specific scenarios, as the Tworpus interface provides controls for filtering and gathering customized collections of tweets, which may serve as the basis for subsequent analyses.

Evaluating a web-based tool for crowdsourced navigation stress tests

We present a web-based tool for evaluating the information architecture of a website. The tool allows the use of crowdsourcing platforms like Amazons MTurk as a means for recruiting test persons, and to conduct asynchronous remote navigation stress tests (cf. Instone 2000). We also report on an evaluation study which compares our tool-based crowdsourced approach to a more traditional laboratory test setting. Results of this comparison indicate that although there are interesting differences between the two testing approaches, both lead to similar test results.
