Synonyms-words that denote the same concept and are interchangeable in many contexts-are grouped into unordered sets (synsets). The main relation among words in WordNet is synonymy, as between the words shut and close or car and automobile. Second, WordNet labels the semantic relations among words, whereas the groupings of words in a thesaurus does not follow any explicit pattern other than meaning similarity. As a result, words that are found in close proximity to one another in the network are semantically disambiguated. First, WordNet interlinks not just word forms-strings of letters-but specific senses of words. However, there are some important distinctions. WordNet superficially resembles a thesaurus, in that it groups words together based on their meanings. WordNet's structure makes it a useful tool for computational linguistics and natural language processing. WordNet is also freely and publicly available for download. The resulting network of meaningfully related words and concepts can be navigated with the browser. Synsets are interlinked by means of conceptual-semantic and lexical relations. Nouns, verbs, adjectives and adverbs are grouped into sets of cognitive synonyms (synsets), each expressing a distinct concept. WordNet® is a large lexical database of English. Citation figures are critical to WordNet funding. When writing a paper or producing a software application, tool, or interface based on WordNet, it is necessary to properly cite the source. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the creators of WordNet and do not necessarily reflect the views of any funding agency or Princeton University.
