Research tools for easier searching, analytics, discovery & text mining of heterogenous and large document sets with free software on your own computer or server
Thesaurus & Grammar
Easy navigation trough many results with interactive filters (faceted search) which aggregates an overview over and interactive filters for (meta) data like authors, organizations, persons, places, dates, products, tags or document types.
Exploration, browsing & preview
Explore your data or search results with an overview of aggregated search results by different facets with named entities (i.e. file paths, tags, persons, locations, organisations or products), while browsing with comfortable navigation through search results or document sets.
View previews (i.e. PDF, extracted Text, Table rows or Images).
Analyze or review document sets by preview, extracted text or wordlists for textmining.
Collaborative annotation and tagging
Tag your documents with keywords, categories, named entities or text notes that are not included in the original content to find them better later (document management) or in other research or search contexts.
Or evaluate, value or assess documents (i.e. for validation).
Alerts & Watchlists (Newsfeeds)
Stay informed via watchlists, activity streams or news alerts: Subscribe searches as RSS-Newsfeed and get notifications when there are changed or new documents or results.
Supports different file formats
No matter if structured data like databases, tables or spreadsheets or unstructured data like text documents, E-Mails or even scanned legacy documents: Search in many different formats and content types (text files, Word and other Microsoft Office documents or OpenOffice documents, Excel or LibreOffice Calc tables, PDF, E-Mail, CSV, doc, images, photos, pictures, JPG, TIFF, videos and many other file formats).
Supports multiple data sources
Find all your data at one place: Search in many different data sources like files and directories, fileserver, file shares, databases, websites, Content Management Systems, RSS-Feeds and many more.
The Connectors and Importers of the Extract Transform Load (ETL) framework for Data Integration connects and combines multiple data sources and as integrated Data Enrichment framework it enhances the data with the analysis results of diverse analytics tools.
Automatic text recognition
Optical character recognition (OCR) or automatic text recognition for images and text content stored in graphical format like scanned legacy documents, screenshots or photographed documents in the form of image files or embedded in PDF files.
Open-Source enterprise search and information retrieval technology based on interoperable open standards
Mobile (Responsive Design)
Open Semantic Search can not only be used with every desktop (Linux, Windows or Mac) or web browser. With its responsive design and open standards like HTML5 it is possible to search with tablets, smartphones and other mobiles.
Metadata management (RDF)
Structure your research, investigation, navigation, document sets, collections, metadata forms or notes in a Semantic Wiki, Drupal or another content management system (CMS) or with an innovative annotation framework with taxonomies and custom fields for tagging documents, annotations, linking relationships, mapping and structured notes. So you integrate powerful and flexible metadata management or annotation tools using interoperable open standards like Resource Description Framework (RDF) and Simple Knowledge Organization System (SKOS).
Using file monitoring, new or changed files are indexed within seconds without frequent recrawls (which is not possible often if many files).
Colleagues are able to find new data immediately without (often forgotten) uploads to a data or document management system (DMS) or filling out a data registration form for each new or changed document or dataset in a data management system or data registry.
