Performance of Two Statistical Indexing Methods, with and without Compound-word Analysis

In Germanic languages, compound words are very common and very productive. There are compound words which are bound and lexicalized and loose their semantic content when split (e.g. albatross or jordgubbe). This category will be referred to as opaque compounds. The opposite of the opaque compounds are the productive compounds, whose parts keep their semantic value when separated (Bjarnadóttir 2003). Among these are the compounds that are used, and sometimes invented, for a special context (e.g. indexeringsmetod).
