Abstract

Obtaining information in short periods of time can make the difference for research or business; therefore it is important to have tools that facilitate the search for information. A visualization technique called information-clustering engine is reviewed: Carrot2  separates the documents found on the Web into groups or clusters, using clustering algorithms that consult various sources of data and then process and display the information obtained. This open-source software significantly reduces the effort involved in information retrieval (IR) and analysis.
