- Abstract
- Homonymy is known to often cause false drops in free text searching in a full text database. The problem is quite common and difficult to avoid in Finnish, but nobody has examined it before. Reports on a study that examined the frequency of, and solutions to, the homonymy problem, based on searches made in a Finnish full text database containing about 55.000 newspaper articles. The results indicate that homonymy is not a very serious problem in full text searching, with only about 1 search result set out of 4 containing false drops caused by homonymy. Several other reasons for nonrelevance were much more common. However, in some set results there were a considerable number of homonymy errors, so the number seems to be very random. A study was also made into whether homonyms can be disambiguated by syntactic analysis. The result was that 75,2% of homonyms were disambiguated by this method. Verb homonyms were considerably easier to disambiguate than substantives. Although homonymy is not a very big problem it could perhaps easily be eliminated if there was a suitable syntactic analyzer in the IR system

- Abstract
- The basic problem in freetext retrieval is that the retrieval language is not properly adapted to that of the author. Morphological segmentation, where words with the same root are grouped together in the inverted file, is a good eliminator of noise and information loss, providing high recall but low precision

- Abstract
- Die Möglichkeiten, die der heutigen Informations- und Wissensgesellschaft für die Beschaffung und den Austausch von Information zur Verfügung stehen, haben kurioserweise gleichzeitig ein immer akuter werdendes, neues Problem geschaffen: Es wird für jeden Einzelnen immer schwieriger, aus der gewaltigen Fülle der angebotenen Informationen die tatsächlich relevanten zu selektieren. Diese Arbeit untersucht die Möglichkeit, mit Hilfe von natürlichsprachlichen Schnittstellen den Zugang des Informationssuchenden zu Volltextdatenbanken zu verbessern. Dabei werden zunächst die wissenschaftlichen Fragestellungen ausführlich behandelt. Anschließend beschreibt der Autor verschiedene Lösungsansätze und stellt anhand einer natürlichsprachlichen Schnittstelle für den Brockhaus Multimedial 2004 deren erfolgreiche Implementierung vor
