  text: This paper presents a novel linguistic information extraction approach exploiting
    analysts’ stock ratings for statistical decision making. Over a period of one
    year, we gathered German stock analyst reports in order to determine market trends.
    Our goal is to provide business statistics over time to illustrate market trends
    for a user-selected company. We therefore recognize named entities within the
    very short stock analyst reports such as organization names (e.g. BASF, BMW, Ericsson),
    analyst houses (e.g. Gartner, Citigroup, Goldman Sachs), ratings (e.g. buy, sell,
    hold, underperform, recommended list) and price estimations by using lexicalized
    finite-state graphs, so-called local grammars. Then, company names and their acronyms
    respectively have to be cross-checked against data the analysts provide. Finally,
    all extracted values are compared and presented into charts with different views
    depending on the evaluation criteria (e.g. by time line). Thanks to this approach
    it will be easier and even more comfortable in the future to pay attention to
    analysts’ buy/sell signals without reading all their reports.
