Semantic Collocation Analytics (Corpus)

Semantic Collocation analytics shows what concepts appear close to what other concepts across the corpus documents. This is done by aggregating results from individual ontology and argumentation model Semantic Collocation analytics together.

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

Parameters

• Max distance. This is the maximum number of words between concept occurrences that will be used to determine collocated concepts. 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 concepts will cross over sentence boundaries in ontologies. This will result in more results, but probably less significant, as they will include concept pairs that span two or more sentences.

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 a cross-table chart showing all collocations, plus an additional chart showing collocations for a selected concept.

For all charts, you can select how collocated concepts 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.

All

The cross-table chart shows concepts along both axes. Blue cells show the collocation value for each concept pair. The value for each cell may correspond to the number of occurrences of the collocated concept pair, or to the minimum, average or maximum distance of the collocated concept pair, depending on the sorting selection in the toolbar.

Selected

This allows you to select a focus concept to display some overall data and a chart for collocated concepts.

The chart shows the collocated concepts along the vertical axis. The horizontal axis shows the distance of each collocated concept 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 concept.

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.

All

The cross-table chart shows concepts along both axes. Blue cells show the collocation value for each concept pair. The value for each cell may correspond to the number of occurrences of the collocated concept pair, or to the minimum, average or maximum distance of the collocated concept pair, depending on the sorting selection in the toolbar.

Selected

This allows you to select a focus concept to display some overall data and a chart for collocated concepts.

The chart shows the collocated concepts along the vertical axis. The horizontal axis shows the distance of each collocated concept 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 concept.

Aggregated

All

The cross-table chart shows concepts from the reference ontology along both axes. Blue cells show the collocation value for each concept pair. The value for each cell may correspond to the number of occurrences of the collocated concept pair, or to the minimum, average or maximum distance of the collocated concept pair, depending on the sorting selection in the toolbar.

Selected

This allows you to select a focus concept to display some overall data and a chart for collocated concepts.

The chart shows the collocated concepts from the the reference ontology along the vertical axis. The horizontal axis shows the distance of each collocated concept 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 concept.
