Presentation Transcript

  1. CASCOT and its coding rules Presentation for DASISH Workshop Venice, 10-11 April 2014 Ritva Ellison Institute for Employment Research

  2. Cascot Editor • Classification files for Cascot are created and modified with the Editor • Each classification has Structure, Index, Rules for coding

  3. Cascot Editor Rules • Downgraded words: words that are considered to be significantly less important than other words, e.g. deputy, junior, person • Equivalent word ends:wait|er, wait|ress • Abbreviations:asst assistant, fe  further education • Replacement words: taylor  tailor, tesco  supermarket • Omitting noise words, e.g. replace ‘part-time’ with nothing • Input modifications: used when the rule absolutely can not be made elsewhere • Word alternatives: words and phrases that should also be tried as possible solution candidates • Conclusions, retired  can not conclude, agent  ambiguous (score 39) • Default coding: a set of words and phrases that should be scored as though they were a different word or phrase

  4. ESS6 data for GB – some examples

  5. New rules for GB - 1 • The problem: • Add a new Default Coding rule to improve performance • The result: • Need to test the effect of the rule thoroughly

  6. New rules for GB - 2 • The problem: • Add two new Replacement Words rules: • The result:

  7. New rules for GB - 3 • The problem: • Add a new Abbreviations rule AB72: • The result:

  8. New rule did not work – why? • Check which rules were evoked  The rule AB72 was not used at all!

  9. The rules that were actually evoked were: AB41 As a result the input text ‘sec school teacher’ was expanded into ‘secretary school teacher’. WA107 As a result also the text ‘clerk school teacher’ was tried.

  10. Try again! • Move the new Abbreviations rule so that it precedes the rule for ‘sec’: • The result:

  11. ESCO DE – potential for rules

  12. ESCO EN – potential for rules

  13. ESCO ES – potential for rules

  14. ESCO FR – potential for rules

  15. ESCO IT – potential for rules

  16. ESCO NL – potential for rules

  17. ESCO SK – potential for rules

  18. How to create a rule • Open Cascot and type in the text in question • Observe the recommendations for the text • Start Cascot Editor • Open the classification with Editor • Select the rule tab you wish to work on • Add a new rule • Save classification • Start Cascot • Open the classification that was edited • Type in the text to test the effect of the rule

  19. Tasks for language groups • Create and test rules for the above cases • For your language, propose • downgraded words • equivalent word ends • abbreviations • conclusions
