Find Text — Co-occurrence
?
Summary

This tool searches for two words at a user-defined distance of words, sentences, lines or paragraphs apart from one another, within an HTML document located either at a user-specified web address or uploaded from the user’s files. If desired, the results can be narrowed to include words only found within certain tags.

Note: When 'Paragraphs' is selected as context, any element name entered by the user will be overwritten by the 'p' (<p></p>) tag. As not all HTML texts use the paragraph tag to identify paragraphs, this may cause some problems with the tool’s results. If so, use a context of word, line or sentence instead.

Please click the ? buttons at the bottom right of each set of options for more information on that set.

For further information on this tool, please see the TADA Wiki's Co-ocurrance entry here. A glossary of terms is also available here.

Summary

This section defines the primary and secondary words or patterns to search for within the source text. A pattern may be a string of characters or a regular expression. The tool will search for the primary and secondary words or patterns within a set distance of one another.

Summary

This section allows the user to define the context type (words, lines, sentences or paragraphs), and how many of that type (context length) to show on either side of each instance of the word or pattern.

Fields

Context

Context can be set to one of four options from the drop menu: words, lines, sentences and paragraphs.

Words
This option places the search term or pattern in context by a specified number of words.

Lines
This option places the search term or pattern in context by a specified number of lines.

Sentences
This option places the search term or pattern in context by a specified number of sentences.

Paragraphs
This option places the search term or pattern in context by a specified number of paragraphs.

Context Length
This drop menu allows users to enter how many words, lines, sentences or paragraphs to show before and after the word or pattern. For example, if the context length is 5 words, every instance of the search term or pattern will be shown surrounded by a total of ten words - the five that precede it, and the five that follow it.
