Carrot2

Carrot2 is a programming library for clustering text. It can automatically discover groups of related documents and label them with short key terms or phrases.

A few years have passed since I last employed Carrot2 for my searches. However, the internet has undergone advancements, as has Carrot2. This search engine, also known as a "search result clustering engine," allows you to search across multiple sources and utilize diverse clustering algorithms to display the information found. Additionally, it gives you the option to present the results as a pie chart or tree map showcasing the most frequently encountered terms during the search. Carrot2 is a speedy and convenient search tool that can provide more insight into the topic under investigation.

Carrot Search Labs

Carrot² gave rise to a number of independent open source projects released under the umbrella of Carrot Search Labs.[9] The following projects are or were published as part of this initiative:

• Randomized Testing: a JUnit test runner with built-in utilities to make every test run slightly different (randomized). Also an ANT task for running JUnit tests on parallel JVMs, with load balancing and other bells and whistles.

• High Performance Primitive Collections for Java (HPPC): Lists, Sets, Maps and other collections of primitives for Java tuned for highest performance and memory efficiency.

• SmartSprites: fully automatic maintenance of CSS sprites; no tedious copying and pasting to the CSS when adding or changing sprited images.

Discontinued projects:

• jSuffixArrays: Several Java implementations of the Suffix Array data structure with different performance and memory characteristics.

• JUnitBenchmarks: A set of extensions for turning JUnit4 tests into performance micro-benchmarks with GC monitoring, time variance measurement and simple graphical visualizations.
