Semantic/Lexical Collocation Analytics (Corpus)

Semantic/Lexical Collocation analytics shows what words appear close to a selected concept across the corpus documents. This is done by aggregating results from individual ontology and argumentation model Semantic/Lexical Collocation analytics together.

This is useful to find out major concept/word associations across the corpus.

Parameters

  • Focus concept. This is the concept from the reference ontology that you want to find across the corpus, and for which nearby words are to be determined.
  • Max distance. This is the maximum number of words before of after an occurrence of the focus concept that will be considered to determine collocated words. Typical values are around 5.
  • Agent. If a reference context exists and you select an agent, only the locutions of speakers linked to this agent will be taken into account.
  • Cross over sentence boundaries. If you check this box, the search for collocated words will cross over sentence boundaries in ontologies. This will result in more results, but probably less significant, as they will include words that are in another sentence as compared to the focus concept occurrence.
  • Include numbers. If you check this box, number words (such as "17" or "-0.25") are also included in the results.
  • Include codes. If you check this box, code words (such as "UNESCO" or "SARS-CoV-2") are also included in the results.
  • Case sensitive. If you check this box, words that differ only in case (such as "word" and "Word") are treated as different words.

Results

Results are given separately for each kind of applicable dependent models (ontologies and argumentation models), plus aggregated. For each of these, results are presented as some overall data plus a chart.

For all charts, you can select how collocated words are sorted from the drop down menu in the toolbar.

Ontologies

The total number of ontologies used by the analytics is shown at the top as "Count". Ontologies are gathered from the following sources:

  • Dependent ontologies of active documents.
Overall data
  • Focus concept occurrence count. This is the number of times that the focus concept occurs in the texts.
  • Collocation count. This is the number of words that were found within the maximum distance of focus concept occurrences.
Chart

The chart shows the collocated words along the vertical axis. The horizontal axis shows the distance of each collocated word to the focus concept. Blue bars show distance ranges, from minimum to maximum distance. Red circles show average distances, and their size is proportional to the number of occurrences of the collocated word.

Argumentation models

The total number of argumentation models used by the analytics is shown at the top as "Count". Argumentation models are gathered from the following sources:

  • Dependent argumentation models of active documents.
Overall data
  • Focus concept occurrence count. This is the number of times that the focus concept occurs in the texts.
  • Collocation count. This is the number of words that were found within the maximum distance of focus concept occurrences.
Chart

The chart shows the collocated words along the vertical axis. The horizontal axis shows the distance of each collocated word to the focus concept. Blue bars show distance ranges, from minimum to maximum distance. Red circles show average distances, and their size is proportional to the number of occurrences of the collocated word.

Aggregated
Overall data
  • Focus concept occurrence count. This is the number of times that the focus concept occurs in the texts.
  • Collocation count. This is the number of words that were found within the maximum distance of focus concept occurrences.
Chart

The chart shows the collocated words along the vertical axis. The horizontal axis shows the distance of each collocated word to the focus concept. Blue bars show distance ranges, from minimum to maximum distance. Red circles show average distances, and their size is proportional to the number of occurrences of the collocated word.
