- Abstract
- Description of an experimental trend-predicting exercise covering a time period as far as 50 years into the future. The Delphi technique is used in soliciting the opinions of experts in six areas: scientific breakthroughs, population growth, automation, space progress, probability and prevention of war, and future weapon systems. Possible objections to the approach are also discussed.

- Abstract
- Die vorliegende Studie untersucht das Potenzial von Mehrwortbegriffen für das Information Retrieval. Zielsetzung der Arbeit ist es, intellektuell positiv bewertete Kandidaten mithilfe des Latent Semantic Analysis (LSA) Verfahren höher zu gewichten, als negativ bewertete Kandidaten. Die positiven Kandidaten sollen demnach bei einem Ranking im Information Retrieval bevorzugt werden. Als Kollektion wurde eine Version der sozialwissenschaftlichen GIRT-Datenbank (German Indexing and Retrieval Testdatabase) eingesetzt. Um Kandidaten für Mehrwortbegriffe zu identifizieren wurde die automatische Indexierung Lingo verwendet. Die notwendigen Kernfunktionalitäten waren Lemmatisierung, Identifizierung von Komposita, algorithmische Mehrworterkennung sowie Gewichtung von Indextermen durch das LSA-Modell. Die durch Lingo erkannten und LSAgewichteten Mehrwortkandidaten wurden evaluiert. Zuerst wurde dazu eine intellektuelle Auswahl von positiven und negativen Mehrwortkandidaten vorgenommen. Im zweiten Schritt der Evaluierung erfolgte die Berechnung der Ausbeute, um den Anteil der positiven Mehrwortkandidaten zu erhalten. Im letzten Schritt der Evaluierung wurde auf der Basis der R-Precision berechnet, wie viele positiv bewerteten Mehrwortkandidaten es an der Stelle k des Rankings geschafft haben. Die Ausbeute der positiven Mehrwortkandidaten lag bei durchschnittlich ca. 39%, während die R-Precision einen Durchschnittswert von 54% erzielte. Das LSA-Modell erzielt ein ambivalentes Ergebnis mit positiver Tendenz.

- Abstract
- Wenig ist heute für den gebildeten Bürger interessanter, als die aktuellen Erkenntnisse der Neurowissenschaften zu verfolgen. Letztere ermöglichen durch bildgebende Verfahren wie z. B. EEG, fMRT oder MEG, dem Menschen "beim Denken zuzusehen". So heißt es zumindest in den Medien. Aktuelle Forschungsberichte zeigen eine Näherung an diese Sichtweise. Kalifornischen Forschern ist es durch eine Hirnmessung jüngst gelungen, mit groer Wahrscheinlichkeit zu erkennen, welches Bild eine Versuchsperson gerade betrachtet. Dazu wurden der Versuchsperson erst 1.750 Bilder mit Naturmotiven gezeigt und die jeweilige Stimulation im Hirn per fMRT gemessen. Geachtet wurde speziell auf visuelle Areale, die in eine dreidimensionale Matrix transformiert wurden. Die einzelnen Segmente heissen Voxel (analog zu zweidimensionalen Pixeln). So entstand eine Datenbank aus Voxel-Aktivitätsmustern. Im folgenden Durchlauf wurden der Versuchsperson 120 neue Bilder gezeigt und anhand der Datenbank die wahrscheinliche Voxel-Aktivität berechnet. Vorausgesagt wurde dann das Bild, dessen tatsächliches Voxel-Muster mit dem berechneten am meisten übereinstimmte. Bei Versuchsperson A wurde eine Trefferquote von 92% erreicht, bei Versuchsperson B immerhin 72%. Die Forscher folgern optimistisch, dass es über ihren Ansatz möglich sein wird, gesehene Bildeindrücke über Hirnmessungen zu rekonstruieren. Hier wird versucht auf Kants Frage "Was ist der Mensch?" auf materialistische Weise näher zu kommen. Im Bezug auf frühere Experimente von Benjamin Libet schließen heutzutage einige Hirnforscher, dass das bewusste Erleben eines Menschen nur Beiwerk von deterministisch ablaufenden Hirnprozessen ist, weil das Erleben neuronaler Aktivität zeitlich hinterherhinkt. Auch wird gefolgert, dass empfundene Willensfreiheit nur eine Illusion ist, obwohl Libet diese harte Schlussfolgerung nicht zieht. Die Ergebnisse solcher Studien sind zwar hochinteressant, doch muss man bei der Interpretation auch hohe Sorgfalt walten lassen, insbesondere wenn es um das Thema Bewusstsein geht. Von philosophischer Seite her hat sich John Searle intensiv mit dem Thema auseinandergesetzt und eine Theorie entwickelt, die alle bisherigen philosophischen Modelle verwirft.
