Detailed Description

generate a word cloud visualization of a text document

Word Clouds, AKA Tag Clouds (https://en.wikipedia.org/wiki/Tag_cloud), are a text visualization technique that displays individual words with properties that depend on the frequency of a word in a document. vtkWordCloud varies the font size based on word frequency. Word Clouds are useful for quickly perceiving the most prominent terms in a document. Also, Word Clouds can identify trends and patterns that would otherwise be unclear or difficult to see in a tabular format. Frequently used keywords stand out better in a word cloud. Common words that might be overlooked in tabular form are highlighted in the larger text, making them pop out when displayed in a word cloud.

There is some controversy about the usefulness of word clouds. Their best use may be for presentations, see https://tinyurl.com/y59hy7oa

The generation of the word cloud proceeds as follows:

  1. Read the text file
  2. Split text into words to be processed Extract words from the text Drop the case of each word for filtering Filter the words Replace words from the ReplacementPairs list Skip the word if it is in the stop list or contains a digit Skip single character words Raise the case of the first letter in each word Sort the word list by frequency
  3. Create a rectangular mask image or read a mask image
  4. For each word Render the word into an image Try to add the word to the word cloud image. For each orientation, see if the word "fits" If no fit, move along a path to try another location

NOTE: A word fits if all of the non-zero word cloud pixels in the extent of the text image are background pixels.

NOTE: The path is an Archimedean Spiral (https://en.wikipedia.org/wiki/Archimedean_spiral)

NOTE: vtkWordCloud has a built-in list of stop word. Stop words are words that are filtered out before processing of the text, such as the, is, at, which, and so on.

NOTE: Color names are defined in vtkNamedColors. A visual representation of color names is here: https://tinyurl.com/y3yxcxj6

NOTE: vtkWordCloud offers Several methods to customize the resulting visualization. The class provides defaults that provide a reasonable result.

BackgroundColorName - The vtkNamedColors name for the background (MidNightBlue). See https://tinyurl.com/y3yxcxj6 for a visual representation of the named colors.

ColorDistribution - Distribution of random colors(.6 1.0), if WordColorName is empty.

ColorSchemeName - Name of a color scheme from vtkColorSeries to be used to select colors for the words (), if WordColorName is empty. See https://tinyurl.com/y3j6c27o for a visual representation of the color schemes.

DPI - Dots per inch(200) of the rendered text. DPI is used as a scaling mechanism for the words. As DPI increases, the word size increases. If there are too, few skipped words, increase this value, too many, decrease it.

FontFileName - If empty, the built-in Arial font is used(). The FontFileName is the name of a file that contains a TrueType font. https://www.1001freefonts.com/ is a good source for free TrueType fonts.

FontMultiplier - Font multiplier(6). The final FontSize is this value times the word frequency.

Gap - Space gap of words (2). The gap is the number of spaces added to the beginning and end of each word.

MaskColorName - Name of the color for the mask (black). This is the name of the vtknamedColors that defines the foreground of the mask. Usually black or white. See https://tinyurl.com/y3yxcxj6 for a visual representation of the named colors.

MaskFileName - Mask file name(). If a mask file is specified, it will be used as the mask. Otherwise, a black square is used as the mask. The mask file should contain three channels of unsigned char values. If the mask file is just a single unsigned char, specify turn the boolean BWMask on. If BWmask is on, the class will create a three channel image using vtkImageAppendComponents.

BWMask - Mask image has a single channel(false). Mask images typically have three channels (r,g,b).

MaxFontSize - Maximum font size(48).

MinFontSize - Minimum font size(8).

MinFrequency - Minimum word frequency accepted(2). Word with frequencies less than this will be ignored.

OffsetDistribution - Range of uniform random offsets(-size[0]/100.0 -size{1]/100.0)(-20 20). These offsets are offsets from the generated path for word layout.

OrientationDistribution - Ranges of random orientations(-20 20). If discrete orientations are not defined, these orientations will be generated.

Orientations - Vector of discrete orientations(). If non-empty, these will be used instead of the orientations distribution");

ReplacementPairs - Replace the first word with another second word (). The each word will also added to the StopList. The second argument can contain multiple words. For example you could replace "bill" with "Bill Lorensen" or, "vtk" with "VTK . Remember that words are always stored internally with lower case, even though the first letter is capitalized in the Word Cloud.

Sizes - Size of image(640 480).

StopWords - User provided stop words(). Stop words are words that are filtered out before processing of the text, such as the, is, at, which, and so on. vtkWordClass has built-in stop words. The user-provided stop words are added to the built-in list. See https://en.wikipedia.org/wiki/Stop_words for a description. The built-in stop words were derived from the english stop words at https://www.ranks.nl/stopwords. Stop words for other languages are also available.

StopListFileName - the name of a file that contains stop words, one word per line (). If present, the stop words in the file replace the built-in stop list.

Title - Add this word to the document's words and set a high frequency, so that is will be rendered first.

WordColorName - Name of the color for the words(). The name is selected from vtkNamedColors. If the name is empty, the ColorDistribution will generate random colors. See https://tinyurl.com/y3yxcxj6 for a visual representation of the named colors.

The class also provided Get methods that return vectors StopWords, SkippedWords and KeptWords.
