A quantitative analysis of the English lexicon was done in the paper. The three electronic dictionaries are under examination: the English Wiktionary, WordNet, and the Russian Wiktionary. It was calculated the quantity of English words and meanings (senses). The distribution of words for each part of speech, the quantity of monosemous and polysemous words and the distribution of words by number of meanings were calculated and compared across these dictionaries. The analysis shows that the average polysemy, the number and the distribution of word senses follow similar patterns in both expert and collaborative resources with relatively minor differences.
