Information
n. 2. any knowledge gained through communication, research, instruction, etc.
Random House Dictionary of the English Language, 1983

Language and the Communication Process
• Language - a “specification” that enables communication
• Semantics - the association between signs or symbols and their intended “meaning”
• Syntax - the rules for ordering and structuring the signs into phrases and sentences
• Pragmatics - the relationship between signs and symbols and the recipient. Broadly, the shared context.

Shared Culture
“It is possible to find the truth without controls, but the process has been demonstrated again and again to be notably inefficient, so that years may be required before it is appreciated that a given treatment is worthless...”

The impact of context on communication
Shared context:• Allows information to be communicated in larger,
more succinct “chunks”.• Drug, analgesic and NSAID are all “chunks”,
yet differ markedly in conceptual complexity.• Enables specialized symbol sets:
• Contrast the amount of information contained in the formula E=MC2 versus that contained in this presentation...
![Page 16: The Lexical Grid 1/14/2005Copyright © 2005 Mayo Clinic1.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e635503460f94b5fd7c/html5/thumbnails/16.jpg)
1/14/2005 Copyright © 2005 Mayo Clinic 16
Contextual Formalism
The degree of formality in a shared context can vary across a wide spectrum:
• Tacit context which is simply presumed• Contextual negotiation proceeding the
actual message• Rigorous and formal rules and documents
describing the form and possible meanings behind every message and phrase.
![Page 17: The Lexical Grid 1/14/2005Copyright © 2005 Mayo Clinic1.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e635503460f94b5fd7c/html5/thumbnails/17.jpg)
1/14/2005 Copyright © 2005 Mayo Clinic 17
Factors Effecting the Degree Contextual Formalism
• Number of participating parties• Formalism needs to increase as number of
participants increase
• Geographic, cultural and temporal proximity of communicators
• The further apart communicators are, the less they can assume
• Amount of shared context• The more you have, the more important it
becomes to be organized
![Page 18: The Lexical Grid 1/14/2005Copyright © 2005 Mayo Clinic1.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e635503460f94b5fd7c/html5/thumbnails/18.jpg)
1/14/2005 Copyright © 2005 Mayo Clinic 18
Factors Effecting the Degree Contextual Formalism
• The cost of imprecise communication• Poetry and literature - low cost (some may argue
actual gain)• Technical and professional - high to very high
cost• What is the cost of assuming the units of a
thrust specification?• What is the cost of assuming the dose of a
prescription?• What is the cost of assuming the century in
which the communication originated?

Clinical Information Today
• Still transitioning from paper to digital
• Existing digital records grew up in an era of scarce resources
• Maximum shared context• High information content per token
• Information is highly filtered• Only preserve what is absolutely necessary
• Context is tacit and local• Sharing information is labor intensive and
imprecise• Mapping between local contextual knowledge
and incomplete and idiosyncratic understanding of target medium

Clinical Information Today
• High degree of tacit shared context• Records require interpretation to be used
externally
• External representations are ‘lossy’• ICD-9, CPT & the like are abstractions and
classifications
• Expensive or impossible to utilize for purposes not originally envisioned by system architects
• e.g. genetics research
![Page 29: The Lexical Grid 1/14/2005Copyright © 2005 Mayo Clinic1.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e635503460f94b5fd7c/html5/thumbnails/29.jpg)

Bioinformatics Research
• Needs high volumes of clinical data• Statistical power requirements• May have to span more than one institution
• May need to include environmental and other factors
• Cross-institutional and regions
• Will often be searching for new information• ‘Raw’ information available to clinician or
laboratory • May not be considered clinically significant
![Page 30: The Lexical Grid 1/14/2005Copyright © 2005 Mayo Clinic1.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e635503460f94b5fd7c/html5/thumbnails/30.jpg)

How do we get there?
• Maximize usefulness of today’s clinical information
• Improve acquisition and recording mechanisms for future clinical information
![Page 32: The Lexical Grid 1/14/2005Copyright © 2005 Mayo Clinic1.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e635503460f94b5fd7c/html5/thumbnails/32.jpg)
1/14/2005 Copyright © 2005 Mayo Clinic 32
How do we get there?
1) Create an explicit, global shared context• Terminology – shared terms, codes, and
precise definitions• Information model – data elements,
relationships and definitional (terminological) links
![Page 33: The Lexical Grid 1/14/2005Copyright © 2005 Mayo Clinic1.](https://reader036.fdocuments.net/reader036/viewer/2022062421/56649e635503460f94b5fd7c/html5/thumbnails/33.jpg)
1/14/2005 Copyright © 2005 Mayo Clinic 33
How do we get there?
2) Map existing information structures onto this grid• Local data elements and structures
common data elements• Local names and descriptions
common terminology• Local codes and classifications
defined in terms of common terminology structure

1/14/2005 Copyright © 2005 Mayo Clinic 34
How do we get there?
3) Define future information systems requirements in terms of a shared information model and terminology• Develop tooling to allow consistent,
granular information capture• Storage resources are no longer the issue• Clinician time and efficiency is the new
bottleneck• Create standards and resources to make
implementation practical

• Migrate to common models and terminology• common shared terminology• well understood shared information models
• Locally enhanced, but common elements remain common
• Tooling to minimize / eliminate translation steps• (semi) structured information entry• Definitions and terminology directly available to
clinician• Entry tools that allow both precision and detail

is needed• Online or downloadable• Push or pull update mechanism• Available 24x7
• Revised and updated in “real-time”• Cross-linked and indexed

Synopsis
The purpose of the Lexical Grid is to provide a framework that:
• Can represent yesterday’s, today’s and tomorrow’s terminological resources as a single virtual structure
• Allow these resources to be cross-linked and indexed
• Consists of building blocks and tools that allow applications and users to take advantage of the content where and when it is needed.

The Heart of the Lexical Grid
The LexGrid Model - a model of terminology that:1) Explicitly names and defines the
things that the LexGrid tools need to reference explicitly
2) Represents “non-semantic” entities as name/value pairs

Import ToolkitUMLS / SQL / SQL Lite
The lexgrid model currently has three different server-based data storage formats. LDAP, SQL Lite and SQL. The converter package is the tooling that we have written to allow you to move data from one format to another. The converter package also allows you to import terminologies directly from a local image of the UMLS database.
