Definition
• Infopragmatics is an efficient method based on
linguistic perspectives that allows Spanish Native
Speakers to get pertinent – not “relevant” information
from commercial academic data bases (ProQuest, Ebsco,
Elsevier).
It consists of three elements:
• A linguistic storm
• A linguistic algorithm
• An uncertainty theorem

Infopragmatics steps

The linguistic algorithm
• This algorithm consists of a series of linguistic operations to solve a variety of problems rised when trying to get pertinent information, as opposed to the relevant one.
![Page 10: UNAM -DGB Rafael Ibarra & Silvia Ballesteros · 2009. 6. 12. · Rafael Ibarra & Silvia Ballesteros Quantitative and Qualitative Methods in Libraries International Conference, Chania,](https://reader034.fdocuments.us/reader034/viewer/2022051900/5feeab19042ff91cea656417/html5/thumbnails/10.jpg)
• A linguistic storm. The lingstorm represents an essential bridge between natural language and controlled vocabulary. It allows the users´ lexical availability.
• A billingual dictionary, and an appropriate thesaurus are essential in this phase. They can be digital or printed.

Uncertainty theorem: I.- If there is no information is
due to...
When users finish their fruitless information search, they end up, commonly, frustrated and full
of uncertainty. How can they know what they missed or did not do well?

Uncertainty theorem
I.- If there is no information is due to...
•User lacks lexical abilities
•Syntax is wrong
•Used terms are not equivalent in meaning
•Context is no the appropriate
•There is nothing in the used data base
II.- If the information does not fit is due to...
•Inappropriate technical language
• Incorrect spelling
• Key words or descriptors are not such
