The Polish OpenCyc lexicon is a set of mappings between OpenCyc symbols and their Polish counterparts. It might be though of as a English-Polish dictionary, but since Cyc contains many abstract concepts, it is better viewed as a set of Polish names for the concepts that are present in Cyc. Due to the fact, that the latest OpenCyc version contains more than 200 thousands of concepts, the mapping covers only part of it -- the concepts that are also present in Umbel, an ontology that was developed on the basis of Cyc, but is devoid of many application-specific Cyc concepts. Still many concepts that are present in Umbel lack mapping, since they are very specific and doesn't translate into Polish (e.g. names of species found only in North America). As a result the current mapping contains approx. 16 thousands of translations for approx. 14 thousands of concepts.
