MAIstro combines the power and functionality of M.A.I. and Thesaurus Master to simplify taxonomy management and creation for document indexing. MAIstro integrates seamlessly into any content pipeline via a well documented API library to help organizations structure their content.

Data Harmony®’s Machine Aided Indexer (M.A.I.) provides fast and accurate document indexing, whether used as an automatic indexing system for large volumes of content, or to speed human indexers’ productivity, all while maintaining editor control and consistency. M.A.I. facilitates the selection of indexing terms from controlled vocabularies, authority files, or full thesauri. M.A.I. presents a list of approved terms to the editor for selection, which saves time looking up terms manually and speeds processing time; this, in turn, saves money and increases productivity.


M.A.I. allows flexibility in document indexing, because the editor can add or reject terms as needed. All editorial actions are gathered by the Statistics Collector, which then submits “hit,” “miss,” and “noise” term lists to the Rule Builder module. This continual, controlled improvement of the categorization rule base results in accurate document indexing and semantic enrichment.

Increased Productivity

Customers have experienced up to a seven-fold increase in productivity using M.A.I. for document indexing, while measurably improving consistency and coverage of individual records. M.A.I. improves consistency by suggesting the same term in the same conditions every time, preventing editorial drift.

MAI Batch GUI (New in Version 3.9)

MAI Batch GUI offers a great new interface to run one or more input folders through the Concept Extractor, in a single operation. The software applies thesaurus terms from your specified Data Harmony (DH) indexing project to a large number of source documents.

M.A.I. and MAIstro users can index their own source documents today in MAI Batch GUI. With your Data Harmony 3.9 Administrative Module open and the DH project running as usual, go to ‘MAI Batch app’ – here are the  interface details.

Deeper Indexing

Indexing documents using M.A.I. mines the entire depth of the vocabulary applied, which improves information retrieval, relevance, and precision for the end user.

Additional Features:

  • M.A.I. operates as an independent utility in managing how your structured vocabularies are applied for indexing of documents
  • M.A.I. can be used in conjunction with Thesaurus Master® for more accurate document indexing and semantic enrichment
  • M.A.I. is written in Java with APIs for interfacing with other software

What M.A.I. users say:

“We have found M.A.I. to be accurate and efficient, meeting and exceeding our expectations. The rule builder is flexible, powerful, and intuitively clear…its term suggestions are right where we want them to be. We are delighted with both the package itself and the technical support and training we have received from Data Harmony.”

Scott Ryan, Development Specialist Cambridge Scientific Abstracts

“Our staffing was going down, the work load was increasing, and we needed more efficient ways to store and move data without major staff intervention. I estimate that M.A.I. has improved our productivity by 50%.”
