    <Paragraph position="0"> morphology Smce the oIgamzaUon of WordNet dlwdes the Enghsh vocabulary into four sepmate domains-nouns, velbs, ad\]ecuves, and adverbs- closely related concepts are often entered in more than one of these domains Many (probably most) of these relatmns can be ~dentffied m terms of denvatlonal morphology, e ~, the noun executzon is derived from the verb execute and so is an example of a deverbal noun WordNet already contmns some of th~s kind of denvatmnal morphology dead\]ecUval nouns are hnked to their root adjecuves (length m derived \[tom long), deadjectival adverbs are hnked to then loot adjecu~es (rapidly Is derived from rapid), and some denommal ad\]ecUves are hnked to then ~oot nouns (cellular m derived from cell) In o~del to mcrease the connecUwty of WordNet it would be desirable to include more such deIlva-Uonal morphology Fol example, denvauonal lelatmns betxxeen nouns and verbs should be palUcularly useful (Hull and Gomez 1996) both de= veIbal nouns (avowal from avow) and denommal verbs (sammarlze from summary) Such connecuons would facilitate the recogmtmn that the same idea can be expressed m different ways, e g, that &amp;quot;He summarized the book&amp;quot; and &amp;quot;He gave a summary of the book&amp;quot; are effecUvel~ eqmvalent m meanmg Sometimes these morphological relations can be picked up from glosses, as when {disagreement} is defined as (the speech act of dlsagreexng or arguing or disputing), but these are generally regarded as unmformaUve definitions, and the leveIse relation may not happen to occur Since many of the words ale polysemous, moxphologmal relatmns should not link words, but synsets that have related meanings Fot example, {execute} meaning (to put to death) should be hnked to {execution} meaning (the act of puttxng a condemned person to death), and {execute} meanmg (to carry out a task) should be hnked to {execution} meaning (the act of doing sometMng successfully), etc And m cases where the concepts of the noun and verb a~e dlffeIent-e g, {womanize} floin {woman}-no semanUc link ~ould need to be cleated</Paragraph>
