      SESY.AI

      Tech

      SESY.AI, our semantic technology.

      SESY.AI orders knowledge by meaning. It catalogues, translates, relates and answers, always citing its sources, on infrastructure we own and operate. Its services to businesses and institutions fund the libraries.

      The circuit

      1. Services for businesses and institutions
      2. Income for the project
      3. New libraries and collections
      4. Open knowledge for every reader

      Semantic

      Meaning, not only words.

      A semantic catalogue relates people, places, times, subjects and sources, so that a person or an AI finds the same record by what it means, in any language. It joins the tools of library science with the semantic web of Sir Tim Berners-Lee.

      Vocabularies

      Natural language mapped to controlled vocabularies, so every way of asking reaches one record.

      Sánchez González, José Fernando (2014), pp. 26–27

      Authority

      One identity for each person, place and work, “in an exact, unique and unambiguous way”.

      Sánchez González, José Fernando (2014), p. 28

      Facets

      Author, domain, territory, language, time and protocol: Ranganathan’s faceted method, extended.

      Linked data

      Dublin Core, MARC 21, JSON-LD and schema.org: records that people and machines read alike.

      How it works

      From document to cited answer.

      Every answer has a source; every record has provenance; every author is credited.

      1. Ingest

        Documents, images, audio and data enter a collection.

      2. Transcription and OCR

        As the Biblioteca Digital Bicentenario offered full-text search through character recognition.

      3. Metadata

        AI proposes descriptions, subjects and facets.

      4. Human review

        A librarian verifies every record.

      5. Publication

        With protocol, licence and provenance.

      6. Answers with citations

        Built on the catalogue, with the degree of certainty stated.

      7. Evaluation

        Feedback and statistics for continuous improvement.

      Sánchez González, José Fernando (2014), sec. 3.3, p. 71

      How SESY.AI funds the libraries

      The engine is commercial. The libraries are open.

      With the printing press the library began to democratize the book, and a true commerce of the book was born. SESY.AI follows that path: its services sustain the libraries, and commerce never enters a library.

      Platforms we build with

      The tools of the rising library.

      Every technology is chosen “with caution and reflection” and must be flexible, accessible, usable, cost-effective, permanent and universal.

      Names and trademarks belong to their owners. They describe the technologies we use and imply no partnership or endorsement.

      Own infrastructure

      The keepers of knowledge own the house that holds it.

      Made to measure

      “Librarians began to produce their own systems, made to measure for their library needs, and in time became the professionals of these technologies.”

      Sánchez González, José Fernando (2014), p. 6

      Secure by design

      Privileges, real-time monitoring, authentication and access control, with independent databases so that one failure never stops the whole system.

      Sánchez González, José Fernando (2014), sec. 3.1, p. 64

      Open source first

      The Bicentennial portal ran on 100% open-source software, adapted to the project and free of costly licences.

      Sánchez González, José Fernando (2014), sec. 3.2, p. 70

      Accessibility and privacy

      For every person, with respect.

      Web accessibility means “access for all, regardless of hardware, software, network infrastructure, language, culture, geographic location and abilities”. NEO Library targets WCAG 2.2 AA, with day and night modes, keyboard navigation and reduced motion. In 2010 the Bicentennial accessibility portal, made with CONADIS, was “an innovation at the federal level”.

      Visits are measured with Google Analytics 4 through Google Tag Manager, with Consent Mode v2: you decide whether analytics cookies are used. Web statistics are read as circulation statistics, to improve the library.
