In their own words
Open Semantic Desktop Search
Open Semantic Desktop Search is free, open-source software for full-text and semantic search, text analytics and mining across large document sets. Its desktop edition comes as a virtual machine appliance for import into VirtualBox; configured shared folders point to documents, and indexing starts when the machine launches. Search supports wildcards, Boolean AND/OR/NOT and fuzzy matching. Multilingual semantic search uses a thesaurus to find synonyms, narrower terms and aliases, while stemming helps find other word forms. Interactive facets group metadata such as authors, organizations, people, dates, tags and document types. Previews can display PDFs, extracted text, table rows and images. Analysis tools include date charts, word clouds, word lists, network graphs and interactive maps. OCR can recognize text in images and scanned PDFs. Connectors include files, feeds, websites, SQL databases, MediaWiki and IMAP email. The desktop appliance is for a single user; a separate server installation is aimed at organizations and research teams. The multilingual virtual machine image is a 4 GB download, and the German desktop image is listed as coming soon.
