  • Semantic Indexing with iKnow

    See how the InterSystems® iKnow text analysis tool can give you insights into data and enable better decisions. Learn how you can incorporate semantic analysis into your applications in the following video series.


    The following videos describe what iKnow is, present use cases, and explain how to incorporate semantic analysis in your applications.



    • An Introduction to iKnow (4m) Page
      iKnow is the InterSystems technology for dealing with unstructured data. Unstructured text is symantically analyzed based on the language it is written in. Identifying concepts and their relationships allow for better business decisions.

      This video introduces you to how iKnow uses linguistic semantic analysis to identify relationships and concepts in text.

        

    • iKnow Use Cases (9m) Page
      This video presents four use cases for iKnow.
      1. Data Exploration.
      2. Trend Analysis.
      3. Content-based Profiling and Clustering.
      4. Information Extraction, Categorization and Mapping
        
    • iKnow Fundamentals (8m) Page
      Basic iKnow terminology is illustrated with user interface web sites that are provided as part of InterSystems technology. How iKnow works is also discussed.

      This video uses quotations from several authors, to build concepts and their relation to other concepts, which are then presented in the provided iKnow user interface web pages.

        

    • iKnow Analytic Basics (11m) Page

      This video shows you how to create and build an iKnow domain and its index using the iKnow APIs and a class. Querying the iKnow domain is done via iKnow APIs and SQL.

        

    • iKnow Queries: Getting at the Data (11m) Page

      iKnow provides several mechanisms to query data in your domain.

      1. Tables are built allowing SQL access to your iKnow data.
      2. ObjectScript API.
      3. SQL Procedures API.
      4. Web Services API.

      This video shows you the various ways to get at your iKnow data.

        

    • iKnow Queries: Filtering and Metadata (13m) Page

      iKnow queries work with all of the sources in a domain unless you limit their scope with filters. Filters are frequently based on entities but can also be based on metadata properties of the sources.

      This video continues the querying discussion with filtering and metadata.

        

    • iKnow Advanced Loading (10m) Page

      Source documents can be loaded into iKnow from a variety of locations. These are defined as part of  your Domain Definition class. One domain can have multiple sources and locations. Virtual Sources are typically a one-time use analytical source.

      This video shows how to include multiple sources in your domain as well as take advantage of Virtual Sources.

         

  • Summary

    In this course you learned what iKnow is and how it is different from other text analysis technology. You also learned how to create and build a domain as well as various ways of querying the iKnow indices. The use of filters and metadata provide additional control over your query results.
