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

Normally do not change these options.

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

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)
