IIT Rende “Taxonomies, Thesauri and Classification Systems” Group

The Institute of Informatics and Telematics, Rende (CS), was established in March 2013.

In previous years it was one of the research units of the Department of Production Systems of the National Research Council.

The IIT’s research activity primarily focuses on Knowledge and information management methodologies, that is, the building and development of taxonomies, thesauri and classification systems for digital document indexing, as well as the development of innovative methods for data codification.

The IIT Unit, Rende, is the Italian representative of LOINC®, the international coding system for laboratory observation and tests results, developed and maintained by the Regenstrief Institute of Indianapolis (USA).

  The activity of the Taxonomies, Thesauri and Classification Systems group focuses on Knowledge and information management methodologies, as knowledge and information acquisition, modeling, formalization, indexing and retrieval; definition of specialized lexicons, thesauri and ontologies in different fields of application. These skills are mainly applied to the field of e-health and Digital Library, with a focus on terminology extraction, metadata definition, semantic mapping and integration, as well as data collection and analysis (e.g. for e-health to define risk profiles). 

Main Research areas

  • Knowledge organization
    Information and Knowledge organization involves research activities related to Library and Information Science (LIS). Regardless of the application domain, KO ranges from document description for indexing and classification performed in libraries, databases, archives etc.
  • Digital library (DL) and digital preservation
    DL is a collection of digital objects that can include text, visual, audio, and video material, stored as electronic media formats (as opposed to print, micro form, or other media), along with means for organizing, storing, and retrieving the files and media contained in the library collection.
  • Controlled Vocabularies
    Controlled vocabularies are organized arrangements of words and phrases used to index content and/or to retrieve content through browsing or searching. Controlled vocabularies are useful to organize information and provide terminology to catalog and retrieve information. They are used in subject indexing schemes, classification schemes, subject headings, thesauri, taxonomies and other forms of knowledge organization systems. In LIS, controlled vocabularies are a carefully selected list of words and phrases, which are used to tag units of information (document or work) so that they may be more easily retrieved by a search.
  • Indexing and Classification
    Indexing is the process of evaluating information and designating indexing terms by using controlled vocabulary that aids in finding and accessing the cultural work record. A controlled indexing language exploits terms that are used by the indexer to describe the content of a document.
  • Classification
    is the process of systematically arranging concepts or other content objects in groups or categories/facets of shared similarity according to established criteria and using terms to identify the classes.
  • Corpus Linguistics
    A Corpus can be defined as a systematic collection of naturally occurring texts (of both written and spoken language). Corpus Linguistics is the study of language as expressed in samples of “real world” text. Originally done by hand, corpora are now largely managed by automated processes.
  • LOINC® work group

    From the note drawn up by the Director of IIT n. 9/2013 of 31/10/2013 the LOINC® work group was established.

    The main activities of the LOINC work group are:

    • represent CNR as the official Italian partner of Regenstrief Institute Inc.
    • maintain the Italian version of LOINC® and all support materials
    • support all Italian LOINC® users
    • manage and maintain the online helpdesk www.loincitalia.it
    • improve interoperability among Italian local systems
