• lc [ attribute ]

    word form lowercase, i.e. case insensitive word form, done is the same as Done. see word form
  • learner corpus [ corpus-types ]

    A collection of texts produced by learners of a language used to study errors and mistakes made by learners of languages. Learner corpora in Sketch Engine can use both error and correction annotation. A special search interface is available to search by the former or the latter or both. see also Setting up a learner corpus
  • lemma [ attribute ]

    Lemma is the basic form of a word, typically the form found in dictionaries. Searching for lemma will also include all forms of a word in the result, e.g. searching for lemma go will find go, goes, went, going, gone. Lemma is case sensitive. go and Go are two different lemmas. see also lemma-lc or compare with word form
  • lemma_lc [ attribute ]

    lemma-lc is a case insensitive lemma. All upper-case characters are converted to lowercase. apple and Apple is the same thing. see lemma
  • Lemmatization

    Lemmatization is a process of assigning a lemma to each word form in a corpus using an automatic tool called a lemmatizer. Lemmatization bring the benefit of searching for a base form of a word and getting all the derived forms in the result, e.g. searching for go will also find goes, went, gone, going.
  • lempos [ attribute ]

    lempos is a combination of lemma and part of speech (pos) consisting of the lemma, hyphen and a one-letter abbreviation of the part of speech, eg. go-vhouse-n. The part of speech abbreviations differ between corpora. Lempos is case sensitive, house-n is different from House-n.  see also lempos_lc
  • lempos_lc [ attribute ]

    lempos_lc is a case insensitive counterpart of lempos. All uppercase letters are converted to lowercase, thus House-n becomes identical with house-n.
  • likelihood [ statistics ]

    a function of parameters of a statistical model, it plays a key role in statistical inference and is the basis for the log-likelihood function. see Statistics in Sketch Engine
  • log-likelihood [ statistics ]

    one of the functions used in computed statistics of Sketch Engine. It is the association measures based on the likelihood function, using in tests for significance (see the log-likelihood calculator and more details)
  • logDice [ statistics ]

    a statistic measure for identifying collocation candidates which is used in the word sketch feature. It is based only on a frequency of words w_1 and w_2 and the bigram w_1w_2, it is not affected by a size of the corpus See logDice in Statistics used in Sketch Engine.
  • Longest-commonest match

    The longest-commonest match is a concept coined by Adam Kilgarriff to name the most common realisation of a collocation, i.e. the chunk of language in which the collocation appears most frequently. The longest-commonest match is part of the word sketch result screen to facilitate the understanding of how the collocation typically behaves.
