License Donate

"TextMiningUtil" is a Kotlin library that provides various utility classes for use in text mining such as text distance and similarity metrics. The library currently provides the following features:

  • Various metrics for measuring the similarity or dissimilarity of texts.
  • Tokenizers for splitting texts into shorter subtexts.

Note that this library was implemented in Java 8 prior to version 2.0.0.

Download

The latest release of this library can be downloaded as a zip archive from the download section of the project's Github page, which is available here. Furthermore, the library's source code is available as a Git repository, which can be cloned using the URL https://github.com/michael-rapp/TextMiningUtil.git.

Alternatively, the library can be added to your project as a Gradle dependency by adding the following to the build.gradle file:

dependencies {
    compile 'com.github.michael-rapp:text-mining-util:2.1.3'
}

When using Maven, the following dependency can be added to the pom.xml:

<dependency>
    <groupId>com.github.michael-rapp</groupId>
    <artifactId>text-mining-util</artifactId>
    <version>2.1.3</version>
</dependency>

Features

In the following a brief overview of the features, which are provided by the library, is given.

Metrics

The library comes with various metrics for measuring the similarity or dissimilarity of texts. The following metrics are provided:

  • DiceCoefficient: Measures the similarity of texts by splitting them into n-grams and calculating the percentage of n-grams that occur in both texts.
  • HammingDistance: Measures the distance between texts by counting the number of corresponding characters that are not equal (can only be applied to texts with the same length). HammingLoss and HammingAccuracy measure the dissimilarity, respectively similarity as a percentage.
  • LevenshteinDistance: Measures the distance between texts by counting the number of single-character edits that are necessary to change one text to another (can be applied to texts with different lengths). LevenshteinDissimilarity and LevenshteinSimilarity measure the dissimilarity, respectively similarity, as a percentage.
  • OptimalStringAlignmentDistance: Measures the distance between text by counting the number of single-character edits and transpositions of adjacent characters that are necessary to change one text to another (only one edit is allowed per substring; can be applied to texts with different lengths). OptimalStringAlignmentDissimilarity and OptimalStringAlignmentSimilarity measure the dissimilarity, respectively similarity, as a percentage.
  • DamerauLevenshteinDistance: Measures the distance between text by counting the number of single-character edits and transpositions of adjacent characters that are necessary to change one text to another (no restrictions; can be applied to texts with different length). DamerauLevenshteinDissimilarity and DamerauLevenshteinSimilarity measure the dissimilarity, respectively similarity, as a percentage.

Tokenizers

Tokenizers allow to split texts into shorter subtexts. The library provides the following implementations:

  • SubstringTokenizer: Allows to split texts into all possible substrings.
  • FixedLengthTokenizer: Allows to split texts into substrings with a specific length.
  • RegexTokenizer: Allows to split texts based on regular expressions (e.g. at whitespace or at certain delimiters).
  • NGramTokenizer: Allows to split texts into n-grams of specific lengths.
