RetrievalWare™ offers a new and better approach to knowledge retrieval, offering people an intelligent alternative to traditional information retrieval systems. Excalibur's APRP™ (Adaptive Pattern Recognition Processing) and Semantic Network technologies provide unprecedented levels of accuracy, flexibility and ease of use for retrieving all kinds of digital information. These unique tools free people from the need to learn arcane and specialized search languages and give them the ability to locate and retrieve information based on its meaningful content.



    Excalibur's Adaptive Pattern Recognition Processing opens a new dimension in digital information retrieval. Modeled on the way biological systems use neural networks to process information, APRP™ acts as a self-organizing system that automatically indexes the binary patterns in digital information, creating a pattern-based memory that is self-optimized for the native content of the data. This unique capability provides a number of powerful advantages for building retrieval applications for virtually any type of digital information, including text, images, video and sounds.

    In text applications, APRP™'s unique capabilities provide many benefits, including:

    Automated, self-organizing pattern indexes
    Eliminates the costly labor of manually defining keywords, building topic trees, establishing expert rules, and sorting and labeling information in database fields. Avoids the inherent subjective biases of categorical indexes.

    Fuzzy searching
    Provides the ability to retrieve approximations of search queries. Has a natural tolerance for errors in both input data and query terms. Eliminates the need for OCR clean up, which is especially useful in applications that handle large volumes of scanned documents.

    High precision and recall
    Gives end-users a high level of confidence that their queries will return all of the requested information regardless of errors in spelling or in "dirty data" they may be searching.

    Language independence
    Supports the rapid development of multi-language text retrieval solutions.

    High performance
    Small pattern indexes and binary pattern matching deliver high-speed retrieval and efficient use of computing resources.


    Excalibur's Semantic Network technology has transformed the way people find relevant information in moderately-sized to extremely large text databases. With Excalibur's Semantic Networks, people can easily and automatically find the information they need, using all of the power and richness of the English language. Excalibur's Semantic Networks leverage true natural language processing, incorporating syntax, morphology and, most importantly, the actual meaning of words as defined by published dictionaries and other reference sources.

    Excalibur's Semantic Networks provide many benefits, including:

    Multiple Lexical Sources
    Excalibur's baseline Semantic Network, created from complete dictionaries, a thesaurus and other semantic resources, gives users a built-in knowledgebase of 400,000 word meanings and over 1.6 million word relationships.

    Natural Language Processing
    Users can simply enter straightforward, plain English queries, which are then automatically enhanced by a rich set of related terms and concepts, to find information targeted to their specific context.

    Morphology
    Recognizes words at the root level, a much more accurate approach than the simple stemming techniques characteristic of other text retrieval software. Does not miss words because of irregular or variant spellings.

    Idioms
    Recognizes idioms for more accurate searches. Processes phrases like real estate and kangaroo court as single units of meaning, not as individual words.

    Semantics
    Recognizes multiple meanings of words. Users can simply point and click to choose the meaning appropriate to their queries.

    Multi-layered dictionary
    Excalibur's baseline Semantic Network supports multi-layered dictionary structures that add even greater depth and flexibility. Enables integration of specialized reference works for legal, medical, finance, engineering and other disciplines. End users can also add personalized definitions and concepts without affecting the integrity of the baseline knowledgebase.
