    Abstract
    We present CopeOpi, an opinion-analysis system, which extracts from the Web opinions about specific targets, summarizes the polarity and strength of these opinions, and tracks opinion variations over time. Objects that yield similar opinion tendencies over a certain time period may be correlated due to the latent causal events. CopeOpi discovers relationships among objects based on their opinion-tracking plots and collocations. Event bursts are detected from the tracking plots, and the strength of opinion relationships is determined by the coverage of these plots. To evaluate opinion mining, we use the NTCIR corpus annotated with opinion information at sentence and document levels. CopeOpi achieves sentence- and document-level f-measures of 62% and 74%. For relationship discovery, we collected 1.3M economics-related documents from 93 Web sources over 22 months, and analyzed collocation-based, opinion-based, and hybrid models. We consider as correlated company pairs that demonstrate similar stock-price variations, and selected these as the gold standard for evaluation. Results show that opinion-based and collocation-based models complement each other, and that integrated models perform the best. The top 25, 50, and 100 pairs discovered achieve precision rates of 1, 0.92, and 0.79, respectively.

    Abstract
    Im Internet und in Online-Diensten wie AOL stehen Hunderttausende von Chat-Räumen bzw. Chat-Kanälen zur Verfügung. Die zeitgleich im Chat eingeloggten Personen können durch das Ablesen vom Monitor und das Tippen auf der Computertastatur untereinander maschinenschriftliche Gespräche führen. Von den 28,3 Millionen deutschen Onlinerinnen und Onlinern, die älter als 14 sind, nutzten im Jahr 200123 Prozent regelmäßig mindestens einmal pro Woche Online-Foren und Chats; bei den 14- bis 19-Jährigen waren es sogar 59 Prozent. Online-Chats werden oft mit Kneipen oder Single-Bars verglichen und somit als gesellige Freizeit-Treffpunkte und Kontaktbörsen charakterisiert. Doch diese Betrachtung ist zu eng, denn Chats erfüllen auch ganz andere Funktionen: Grob lassen sich Off-Topic-Chats (ohne feste Themen zum freien Plaudern und Flirten) von On-Topic-Chats (mit vorgegebenen Themen) abgrenzen. On-Topic-Chats kommen seltener im Webchat und häufiger im IRC (Internet Relay Chat) vor. Oft sind sie dem Wissensaustausch über Computerthemen gewidmet. Daneben existieren im IRC zahlreiche stark frequentierte Channels zum Tausch von Bildern, Musikstücken und Computerprogrammen, bei denen es um Transaktion und nicht um Kommunikation geht.

    Abstract
    Digitalisierung ist, wenn man ein endliches Alphabet nimmt und damit Worte und Sätze herstellt, die einen Inhalt kodieren. Es ist ziemlich egal, ob das mit den Ziffern 0 und 1 oder mit gedruckten Buchstaben geschieht. Digitalisierung führt in unserer Lebenswirklichkeit aber zu einer immer weitreichenderen virtuellen Analogisierung auf der Bedeutungsebene. Menschen ticken analog. Wir können diese analogen Bilder und Gedanken in unseren Köpfen auf die Realität zurückführen oder auf sie anwenden. Die massenhafte Nutzung von Computern, Tablets oder Smartphones ist nur möglich, weil deren Oberfläche graphisch - also analog - gestaltet wurde. Die Geräte hätten nie solch eine große gesellschaftliche Bedeutung gewonnen, wenn nicht ermöglicht worden wäre, dass Laien diese Geräte über Bilder und Graphiken bedienen. Computer sprechen uns als Augentiere an, erst recht, seitdem bewegte Bilder als zu vermittelnde Inhalte hinzugekommen sind. Die sind analog, aber bilden - und das ist das Entscheidende - oft genug eine zum großen Teil künstliche oder gar virtuelle Realität ab.
