Food and Agriculture Organization of the UN Library and Documentation Systems Division GILW FAO's activities on Thesauri and Terminology Systems 1) Form versus meaning: a) Traditional Search The system gets records from different portals using the string vessel

Food and Agriculture Organization of the UN Library and Documentation Systems Division GILW FAO's activities on Thesauri and Terminology Systems 1) Form versus meaning: a) Traditional Search FAOBIB results Using a free text search, the system retrieves all records containing the string “vessel” including records not pertinent to the user’s intended meaning of the term Using a keyword search, the system retrieves 0 results as the thesaurus used in this portal does not use vessel as a keyword

Food and Agriculture Organization of the UN Library and Documentation Systems Division GILW FAO's activities on Thesauri and Terminology Systems 1) Form versus meaning: b) Concept Search In a concept based search the system retrieves all meanings represented by the term vessel. For example: - vessel can refer to the concept blood vessel - vessel can also be interpreted as ship

Food and Agriculture Organization of the UN Library and Documentation Systems Division GILW FAO's activities on Thesauri and Terminology Systems 2) Implemented functionalities : a) synonym search The same records will be retrieved regardless of the specific synonyms or singular/plural forms that the user uses to refer to a concept.

Food and Agriculture Organization of the UN Library and Documentation Systems Division GILW FAO's activities on Thesauri and Terminology Systems 2) Implemented functionalities : b) multilingual capability The system is also able to understand a concept even when different languages are used.

Food and Agriculture Organization of the UN Library and Documentation Systems Division GILW FAO's activities on Thesauri and Terminology Systems 2) Implemented functionalities : c) terminology brokering User query terms are converted into the respective corresponding variants used in a given information system

Food and Agriculture Organization of the UN Library and Documentation Systems Division GILW FAO's activities on Thesauri and Terminology Systems 2) Implemented functionalities : d) disambiguation When the query term is ambiguous all concepts that correspond to that term are displayed to the user and disambiguated using the parent concept

Food and Agriculture Organization of the UN Library and Documentation Systems Division GILW FAO's activities on Thesauri and Terminology Systems 2) Implemented functionalities : e) related concepts Concepts related to the user query are displayed (e.g. for query refinements, etc.)

Food and Agriculture Organization of the UN Library and Documentation Systems Division GILW FAO's activities on Thesauri and Terminology Systems 2) Implemented functionalities : f) query expansion (ex. 1) The query can be refined using one or more related concept(s)

Food and Agriculture Organization of the UN Library and Documentation Systems Division GILW FAO's activities on Thesauri and Terminology Systems 2) Implemented functionalities : f) query expansion (ex. 2) To improve query results (in terms of quality and quantity), it is possible to select one or more translations or related terms...

Food and Agriculture Organization of the UN Library and Documentation Systems Division GILW FAO's activities on Thesauri and Terminology Systems...The query will then take into consideration all selected lexicalizations to improve the query. The system will broker the refined query using the terms from a given portal..
