چکیده

Wir haben über 570 millionen Twitter-Nachrichten aus einem Zeitraum von 8 Monaten untersucht und festgestellt, dass das tracking einer kleinen Anzahl von Schlüsselwörtern uns erlaubt, Influenzaraten und das Alkoholverkaufsvolumen mit großer Genauigkeit zu schätzen. Wir validieren unseren Ansatz anhand von Regierungsstatistiken und finden starke Korrelationen mit Influenza-artigen Erkrankungen, die von den USZentren für Krankheitskontrolle und –prävention herausgegeben werden (r(14) = .964, p < .001) und mit den Alkoholverkaufsvolumina, die vom USZensus-Amt veröffentlicht werden (r(5) = .932, p < .01). We analyze the robustness of this approach to spurious keyword matches, and we propose a document classification component to filter these misleading messages. We find that this document classifier can reduce error rates by over half in simulated false alarm experiments, though more research is needed to develop methods that are robust in cases of extremely high noise (e.g. Schweinegrippe). Lightweight methods to estimate influenza rates and alcohol sales volume from Twitter messages

This study seeks to extend research of this kind to a new and less traditional written genre: song lyrics. We applied the computational tools Coh-Metrix and Linguistic Inquiry and Word Count to a corpus of 35 songs e...

Rocking pneumonia

Ever since Chuck Berry coined the term "rocking pneumonia" in his 1956 song "Roll over Beethoven", pneumonia has been mentioned frequently in modern blues and rock songs.

Identifying singers of popular songs

In this paper, we propose to identify the singers of popular songs using vibrato characteristics and high level musical knowledge of song structure. The proposed framework starts with a vocal detection process followed by a hypothesis test for the vocal/non-vocal verification. This method allows us to select vocal segments of high confidence for singer identification. From the selected vocal se...
