The key technical and functional characteristics of AFS are:
- Multi-source indexing: file servers, static or dynamic web sites, databases, XML streams, e-mail, digital catalogs, directories, or else.
- Multi-format indexing: HTML, PDF, XML, RDF, text, RTF, Word, Excel, PowerPoint, DocBook, OpenDocument, SQL Databases.
- Multi-language indexing: automatic language detection, categorizing and filtering per language, inflection management (singular/plural, gender forms, conjugations), recognition of idiomatic expressions and their context, integration of dictionaries and synonyms.
- Ontologies-based indexing: Assimilation of thesauri is an essential element of any rigorous documentary approach in the corporate context and for e-commerce catalog searches. AFS is one of the few search solutions with native ontologies support at indexing time, enabling extended semantic functions during queries and automatic categorization based on extracted taxonomies.
- Multiple search methods are available depending on the sources and the data: plain text (all boolean operators), fuzzy search, multi-criteria search, semantic search, parametric search, faceted search, autocompletion, multi- and cross- lingual search.
- Fully customizable results format: result stream available in XML, integration using XSLT to generate HTML, or using a set of AFS widgets based on Ajax technology.
- Secure data and searches: encryption of data and transmissions, support of corporate information access strategies, dynamic connection to authentication methods (SSO, LDAP, and so on) for access rights enforcement.
- Configuration and administration are simple and powerful using a complete Back Office: statistics, tools for query analysis, referencing tools, vocabularies and ACP (autocompletion) management, configurations editor, Dataflow monitor, and so on.
- Full standards compliance: development in C++, Python, and Java, respecting Posix standards. As for XML, RDF, SKOS, OWL, and SPARQL, AFS already integrates Semantic Web proposals, making it one of the most up-to-date solutions on the market.
In addition to the technical aspects, an information access solution must above all guide end-users and provide them with the means to navigate in an information space while integrating the vendor's business strategy. Antidot solutions provide numerous functionalities: categorization, clustering, consolidation, spelling correction and suggestion, contextual expressions, and so on.
