public FrequencyAnalyzer(String filename)
```
    INTERNAL: Loads a frequency table as a resource. The format is a plain text file where each line is 'term;factor' where factor is a real in the range 0-1. The score of the term after classification is multiplied with the factor. Thus, a factor of 0.5 will reduce the score of the term by half.
