The quality of ontology alignments is evaluated by comparing to reference alignments and calculating general measures, i.e., precision, recall and F-measure. These measures, however, only provide an overall assessment of the alignments’ quality, but do not reveal differences and commonalities between alignments at a finer-grained level such as, e.g., regions or individual mappings. This demands...

Multiple alignments among genomes are becoming increasingly prevalent. This trend motivates the development of tools for efficient homology search between a query sequence and a database of multiple alignments. In this paper, we present an algorithm that uses the information implicit in a multiple alignment to dynamically build an index that is weighted most heavily towards the promising region...
