WORDNET: a lexical database for the English language (Priceton Universiyt)
About WordNet
WordNet® is a large lexical database of English, developed under the direction of George A. Miller. Nouns, verbs, adjectives and adverbs are grouped into sets of cognitive synonyms (synsets), each expressing a distinct concept. Synsets are interlinked by means of conceptual-semantic and lexical relations. The resulting network of meaningfully related words and concepts can be navigated with the browser. WordNet is also freely and publicly available for download. WordNet's structure makes it a useful tool for computational linguistics and natural language processing.

Online English - Persian Dictionary
The modest English-Persian dictionary on the previous page is a transliteration-based, platform-independent, easy-to-use program. As the transliteration scheme, it uses the "mikhi" alphabet, first designed by Mash Cheragh-Ali in his famous Gerdsooz program. Images are used to display Persian words, so that there is no need to download any fonts, although there is also the option of using standardized or dynamic fonts. The display flexibility makes the program platform-independent, so that you can also use it on Macintoshes and Unix-based machines.
