Collocation Search shows all the words collocating with the target word within the range of N-3 (3 words before the target) to N+3 (3 words after the target). This kind of output,
which is sometimes called a positional collocation table, helps to examine the lexical environment in which a target word appears.
Users can choose a statistical measure to identify salient collocations from
LL (log likelihood)
MI (mutual information score)
In many cases, Raw freq, and LL tend to evaluate high frequent common collocations, while MI tends to evaluate low frequent and peculiar collocations (Ishikawa, 2012).
Wordlist search produces a frequency table of all the words appearing in (a part of) the corpus. Users can choose between a case sensitive search ("you" and "You" as different words) and a case insensitive search ("you" and "You" as one word). Also, users can choose between a word form search ("play" and "plays" as different words) and a lemma search ("play," "plays," "played," "playing" as one word). The case-insensitive lemma search setting usually produces a general versatile list.
Freq graph Search
Freq graph search produces a per-million-word (PMW) freq graph of a chosen word. Users can choose (i) international search or (ii) domestic search. The former shows you how often the word is used by learners in different countries; the latter shows you how often the word is used by learners at different L2 proficiency levels.
International comparison: You can see how often a word is used by participants in different countries and areas.
Domestic/ Proficiency comparison: You can see how often a word is used by learners in a particular country/ area and at different L2 proficiency bands.
In this case, in order to guarantee validity in a comparison, learners' proficiency levels are automatically limited to B1_2 and B2 only. For a more detailed comparison, you had better use the download version.
