Addressed Problems

This tool address the problem of fast, content based, identification of specific documents from a large collection of documents. The documents in text formats are indexed; fast full text search over indexed collection is then possible. The motivation for implementing another search engine was to have an easily extendable and configurable document indexing tool to evaluate novel methods for information retrieval, documents statistical analysis and lemmatization and stemming methods for Slovak language.


The tool consists of two logically separated parts - document indexing and full-text search

RFTS functionality in conjunction with Corporate Memory can be accessed locally (using JAVA interfaces or command line tools) as well as remotely using RPC calls or Web Service interface. The remote access and Web Service interface allows easy integration of the RFTS indexing and search solution in other components and allows rapid prototyping of new tools that require full-text search or some form of statistical analysis of document collection.
