Control Panel Generate Concept Seeds
Leximancer automatically generates seeds on first pass Determines word frequencies (how often a word
occurs), determines Name-like, word-like, and compounds
This interface provides a method to control how this step works
Text Processing Settings specifies how actual text is processed
Concept Seeds Settings controls concept seed generation
Generate Concept Seeds
Generate Concept Seeds Text Processing
Check tagging for folder names and/or
file names to make tags for later comparison.
Finds tags in the loaded data. Ex: Mike: and Therapist:
associates text following a speaker label with that person
until next speaker label.
Prose off (set to 0) for
conversations, tweets, all research
Performs stemming but should be off for first run

Control Panel Generate Thesaurus
In this phase, Leximancer develops tailored dictionaries for the concept “seeds” (starting words)
It then generates a list of weighted terms (a thesaurus) that constitute evidence for the presence of each concept
High-relevance evidence words occur commonly in contexts where the concept is discussed in the text, and rarely where it is not (these evidence words are what you see in the thesaurus with their z-scores)
Sentences may contain several concepts
Generate Thesaurus
Concept Seeds allows you to edit, remove, and add to the concepts generated from Leximancer. You can also add your own seeds to guide Leximancer towards your particular concepts of interest.
Thesaurus Settings gives you the opportunity to control how the thesaurus is created.
Generate Thesaurus cont
Generate Thesaurus: Concept Seeds
Auto Concepts: Concepts found by Leximancer. You can edit and remove.
Auto Tags: Tags found by Leximancer. These came from your tag settings for folder and file names, spreadsheet column headers, dialog labels.
User Defined Concepts: Place to add your own concepts. Used if Leximancer did not find these numerically important.
User Defined Tags: To locate keywords relative to concepts, but no thesaurus is generated. Example: Insert codeword(s) into your text and Leximancer will identify concepts around that word.
Download and Upload: Save and restore.
The Sentiment Lens looks at positive and negative sentiment in your text
Clicking this button loads predefined list of sentiment terms good, like, bad, poor
_favterms common favorable terms
_unfavterms negative terms
_negation terms under User Defined Tags (don’t want as concepts) Never, no, not, nothing
Sentiment Lens
In thesaurus, click on _unfavterms Lists words found with
unfavorable terms score is z-score

Control Panel Run Project
Run Project Compound Concepts
This editor allows for the combination of like concepts,
synonyms, and other possibilities into a single
concept.
Leximancer will add this new
concept as another single
concept for the Concept Map,
Network Map, and all
statistics. The original two
concepts will remain. Thus,
thesaurus and map for
individuals and combination
for comparison.
For this example, Fukishimi and tsunami are combined.
Run Project Concept Coding Settings
The most common use of this is to tag or kill concepts. Kill removes all data where that concept occurs.
Warning: Advanced feature, will remove data. Be careful!
Tags on the map.
Run Project Project Output Settings
Normally do not change these options.
Concept Map provides control for the Concept Map buttons
defaults.
We will cover Insight Dashboard as a separate
topic.
The concept map is linked to a text browser Valuable exploratory tool From the browser you can drill down into the
text Learn what the concepts refer to Investigate the nature of concept relationships
Query Tab Queries entire data set Syntax WORD: NAME: TERM: implicit coding in
results Booleans AND and OR and NOT supported
Data Querying
Researcher creates all seeds for concepts Useful for large text collection where only a few themes
are to be explored; zoom into particular issue Process
1.Load data2.Turn off Automatic Concept Identification3.Enter your concepts into Edit Emergent Seeds4.Tell Thesaurus Learning how many related concepts5.Run
Concept Map with related concepts and thesaurus created for your concepts; everything on that map relates to your issues
Profiling
Detailed data; mostly quantitative report Quadrant Diagram (more later) Must have set up Tags (folders, files,
spreadsheet: auto-generated) Particularly useful when you want to
examine Attributes (independent variables) Certain categories (dependent variables)
