4 Generate Concept Seeds Leximancer automatically generates seeds on first passDetermines word frequencies (how often a word occurs), determines Name-like, word-like, and compoundsThis interface provides a method to control how this step worksText Processing Settings specifies how actual text is processedConcept Seeds Settings controls concept seed generation
5 Generate Concept Seeds Text Processing Check tagging for folder names and/orfile names to make tags for later comparison.Prose looks for English grammar and sentences. If data are not clean or sparse, turn this to 0.Dialog tags are also used to span 2 sentence text blocks.Prose off (set to 0) for conversations, tweets, all researchFinds tags in the loaded data.Ex: Mike: and Therapist: associates text following a speaker label with that person until next speaker label.Performs stemming but should be off for first run
6 Generate Concept Seeds Concept Seeds Normally do not change these options.
8 Generate ThesaurusIn 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 conceptHigh-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
9 Generate Thesaurus cont 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.
10 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.
11 List of positive and negative terms tailored to your dataset. Sentiment LensThe Sentiment Lens looks at positive and negative sentiment in your textClicking this button loads predefined list of sentiment termsgood, like, bad, poor_favterms common favorable terms_unfavterms negative terms_negation terms under User Defined Tags (don’t want as concepts)Never, no, not, nothingThe negation handle not good no happinessThe lens will create _favterms and _unfavterms concepts with relationships and frequencies in the thesaurus.List of positive and negative terms tailored to your dataset.

13 Generate Thesaurus Thesaurus Settings Normally do not change these options.If very small text collection, may turn off Learn Concept Thesaurus for keyword coding. Hand coders typically like to do this.
15 Run Project Compound Concepts This editor allows for the combination of like concepts, synonyms, and other possibilities into a single concept.For this example, Fukishimi and tsunami are combined.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.
16 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.
17 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.
18 Data Querying The concept map is linked to a text browser Valuable exploratory toolFrom the browser you can drill down into the textLearn what the concepts refer toInvestigate the nature of concept relationshipsQuery TabQueries entire data setSyntax WORD: NAME: TERM: implicit coding in resultsBooleans AND and OR and NOT supportedTERM is keyword
