Blumenstock, Joshua E. (2011): Using mobile phone data to measure the ties between nations. In: Proceedings of the 2011 iConference 2011. pp. 195-202.

We introduce a novel method for measuring and evaluating the social ties between nations. Patterns of international communication, and in particular the volume and direction of international phone calls, reflect the interpersonal connections between the people of different countries, and add nuance to the coarse indicators more commonly used in the literature. This paper presents a preliminary investigation of the empirical properties of this metric using a log of all international phone calls to and from Rwanda. We find that patterns of international outgoing and incoming calls closely parallel patterns of international exports and imports. The fine-grained temporal resolution of the data also reveals international dynamics not captured in existing metrics. For instance, we observe spikes in communication that appear unrelated to economic ties following significant events such as natural disasters, elections, and soccer matches. We conclude with a discussion of the strengths and weaknesses of this metric, and point to promising directions for future research.

Blumenstock, Joshua E. (2008): Size matters: word count as a measure of quality on wikipedia. In: Proceedings of the 2008 International Conference on the World Wide Web 2008. pp. 1095-1096.

Wikipedia, "the free encyclopedia", now contains over two million English articles, and is widely regarded as a high-quality, authoritative encyclopedia. Some Wikipedia articles, however, are of questionable quality, and it is not always apparent to the visitor which articles are good and which are bad. We propose a simple metric -- word count -- for measuring article quality. In spite of its striking simplicity, we show that this metric significantly outperforms the more complex methods described in related work.
