cmd.csp.similarity

A library implementing different string similarity and distance measures for ease of use. A dozen of algorithms (including Levenshtein edit distance and sibblings, Jaro-Winkler, Longest Common Subsequence, cosine similarity etc.) are currently implemented. Used in the Cognitive Service Platform cmd.csp for NLP and classifier part.

Prerequisites

There are no prerequisites.

Included dependencies:

<dependency>
    <groupId>net.jcip</groupId>
    <artifactId>jcip-annotations</artifactId>
    <version>1.0</version>
</dependency>

Installing/Usage

To use, merge the following into your Maven POM (or the equivalent into your Gradle build script):

<repository>
  <id>github</id>
  <name>GitHub swelcker Apache Maven Packages</name>
  <url>https://maven.pkg.github.com/swelcker</url>
</repository>

<dependency>
  <groupId>cmd.csp</groupId>
  <artifactId>cspsimilarity</artifactId>
  <version>1.0.0</version>
</dependency>

Then, import cmd.csp.postagger.*;` in your application :

// Example
import cspsimilarity.*;
...
	private NormalizedLevenshtein engineNL = new NormalizedLevenshtein();
	private JaroWinkler engineJW = new JaroWinkler();
	private MetricLCS engineMLCS = new MetricLCS();
	private NGram engineNGRAM = new NGram(3);
	private Cosine engineCOSINE = new Cosine(9);
	private Jaccard engineJACARD = new Jaccard(9);
	private SorensenDice engineSOREDICE= new SorensenDice(9);
...
    String source = (sourceText);
    String search = (toSearch);

    double sS=0d;

    sS=(engineNL.similarity(source, search));
    sS=(engineJW.similarity(source, search));
    sS=(1d-engineMLCS.distance(source, search));
    sS=(1d-engineNGRAM.distance(source, search));
    sS=(engineCOSINE.similarity(source, search));
    sS=(engineJACARD.similarity(source, search));
    sS=(engineSOREDICE.similarity(source, search));
