    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.

    Content
    Nimmt man noch hinzu, daß 35 Prozent (hochgerechnet 22 Millionen Bürger) glauben, Kinder, die den Umgang mit dem Internet nicht beherrschen, seien auch - was immer das heißen mag - privat benachteiligt, dann läßt sich bemerken, daß das Internet für viele offenbar bereits mindestens den Stellenwert der früheren Alphabetisierung einnimmt. Man könnte gar vermuten, daß diese mitsamt anderen Grundkenntnissen hintan gesetzt wird, wenn die Hälfte der Haushalte mit des Satz übereinstimmt, daß die Kinder so früh wie möglich ans Internet herangeflihrt werden müßten. Aber, wie gesagt, bei Befragungen, die nur bestimmte Meinungen abhaken, fallen Zwischentöne und reflektierte Meinungen schlicht unter den Tisch. Bei 34 Prozent der Haushalte herrscht die Meinung vor, daß die Schulen für die Internetkompetenz genug machen, 74 Prozent sehen Eltern oder ältere Geschwister in der Pflicht, dem Web-Nachwuchs die notwendigen Fertigkeiten nahezubringen. Wie auch immer, so scheint die Intemetnutzung bereits ziemlich hoch zu sein. 25 Prozent der 6- bis 18-Jährigen gehen mehrmals im Monat, 30 Prozent mehrmals in der Woche, 9 Prozent mehrmals täglich ins Internet, wobei bei den unter 14-Jährigen schon 47 Prozent mehrmals wöchentlich online sind. Nur 26 Prozent haben nach der Befragung noch keine Erfahrung mit dem Internet, was sich aber bei 9 Prozent noch in diesem Jahr ändern soll. Lediglich 15,8 Prozent der Befragten gaben an, dass eine Internetnutzung "nicht geplant" sei. Für den Standort Deutschland ist erfreulich, daß sich 83 Prozent der Kinder und Jugendlichen "regelmäßig" über das Internet "gezielt" Informationen beschaffen, auch wenn wir nicht genau wissen, um welche Art der Informationen es sich dabei handelt. Bei der Befragung ging es um spezielle Interessen (Sport, Hobby etc.), was dann schon wahrscheinlicher klingt.
