Isobel Description

Open source knowledge management system and framework Isobel works out of the box, but it's meant mainly as a framework to build complex information retrieval and analysis systems.Isobel can be functionally divided in two subsytems, Isobel Analyzer (the analysis subsystem) and Isobel Gatherer (the crawling and filtering subsystem). For a more flexible solution, the two subsytems can also be used separately.Isobel Gatherer offers ready to use services like multi protocol content fetching with fine grained scheduling, formats conversion (pdf, doc, etc.), Hyperlink graph storage and analysis, content storage and indexing, ontology services, xml configuration, logging and statistics.On top of this services a pipeline plug-in model allows the programmer to easily extend the system with specific advanced functions.Isobel Analyzer unleashes the power of the IBM UIMA architecture allowing for the reuse of analysis components developed for this architecture.NOTE: Isobel is licensed and distributed under the terms of the Apache Software License. Here are some key features of "Isobel": · MultiProtocol fetching (HTTP, FTP, File system, db fetching) · Highly configurable scheduling · Document formats conversions (PDF, DOC, RTF) · Graph Storage · Graph structure analysis · XML Content storage · XML Configuration · Python scripting · Ontology service interface (word synonyms, hyponyms, hypernyms) · Pipeline plug-in model for extensions · UIMA analyzers reuse · Log4J logging · Indexing with Lucene · Language guessing with NGramJ
