• ALDF – Average Logarithmic Distance Frequency [ statistics ]

    a modified frequency that prevents the result to be excessively influenced by one part of the corpus (e.g. one or more documents) which contains a high concentration of the token. If the token is evenly distributed across the corpus, ALDF and absolute frequency will be similar or identical. In comparison with ARF (Average Reduced Frequency), ALDF is calculated from the average distances between the tokens, not the frequency of the token. see also ALDF definition
  • alignment

    Alignment is a term used in connection with parallel corpora. A parallel corpus consists of a text and its translation into one or more languages. Parallel corpora need to be divided into segments. A segment usually corresponds to a sentence. Alignment refers to information that tells Sketch Engine which segment (sentence) in one language is the translation of which segment (sentence) in another language. The easiest way to provide the alignment information to Sketch Engine is to upload the data in a tabular format (e.g. Excel).  Alternatives that can account for more complex alignment are also available. see Build a parallel corpus

In comparison with ALDF (Average Logarithmic Distance Frequency), ARF is calculated from the frequency of the token, not distances between the tokens. see also ARF definition
  • Attribute

    An attribute can refer to: A possitional attribute - information added to each token in a corpus, e.g. its lemma or part of speech. A structure attribute - information added to a structure in a corpus, often called metadata
