Are there available resources that classify the common words (used in daily life for communications) in the form of a hierarchy according to their underlying concepts (possibly also w.r.p.t. synonyms/antonyms), analogous to classification of the special words used in many scientific fields, e.g. in medicine where the diverse illnesses are classified into a hierarchy (that is reflected at a higher level in the courses taught in the universites and in the structures of the hospitals)?

    Do you mean something like the semantic fields used by a thesaurus, e.g., Roget's? Jan 23, 2016 at 17:00
  • I have never used Roget. But the theasurus I possess apparently couldn't help me much to establish a hierarchy of the genre I depicted. Jan 24, 2016 at 14:57
  • I just got a hint to UBY ukp.tu-darmstadt.de/data/lexical-resources/uby which seems to be a highly sophisticated software that is relevant for my purposes. If someone has experiences with it, I should appreciate to know of them. Feb 3, 2016 at 13:22

It is not clear to me how fine-grained the resource should be, but for a starter there is the Princeton Wordnet.

For specialised domains several ontologies exsts (some free, some to be licenced).

  • I clicked on "ongologies" but got error message "server not found". I prefer to have somewhat more fine-grained recources than Wordnet. Jan 24, 2016 at 14:40

Babelnet is has word senses for words in many languages.

For example, for [get]:

  • GET the HTTP method
  • get n - divorce document
  • get n - male's offspring
  • get v - meaning to understand
  • get v - meaning to obtain

It includes data from Wiktionary, Princeton WordNet et altri.

  • Word sense is not what I primarily need but the position of a word in the hierarchy of concepts (e.g. what is "nut" in relation to "food" and what are the different kinds of nuts). Jan 26, 2016 at 10:16
