Moriarty Score:

  • The relative negativity of a diary entry
  • Used to measure the intensity of an unhelpful thought
  • Measured by density of negative words
    • 0% = 0
    • 25% = 20 (maximum)
    • eg
      • it’s unbearable, all I can think is how dreadful and fearful I find myself in these difficult situations.
        • 4/18 – 22% negative word density.
        • Moriarty Score – 18 (rounded up from 17.6)

The Mark1 Prototype I presented on Monday involved a scoring system devised in response to the requirements for the service to be indicative of ‘spikes in emotional volatility’ or ’emotional disruptions’.

This scoring system, currently called a Moriarty Score, is influenced by the moriarty.ttf font I made last week.  The font gives a visual overview of how negative a portion of text is by transforming ‘negative feeling words’ into from a horizontal line into a wave.



The Moriarty Score I devised for MK1 is a little more sophisticated.

The system detects how intensity of the negativity in a group of text messages. This is represented on a scale of 0-20 illustrated by a row of dots.





These scores are measured by the density of negative words in a portion of text. The upper limit is 25% (one in four words are negative) which renders a score of 20/20.


This upper limit was decided upon from analysing my own thought diary records and recognising that it was near impossible to write a coherent passage of  text with a negative word density of more than 25%.

If this density or greater is achieved, the passage must represent deeply intense and the individual must be incredibly distressed.


However, sometimes the system won’t get it right, and as a result an adjusting mechanism must be built in.


Users can respond with commands which allows them adjust the Moriarty Score to match their current perceived ‘intensity level’.


Users only get a reply with the Moriarty Score after inputting their thoughts. This is due to the importance of  “capturing how/what you are thinking” for support professionals (therapists, doctors etc). The user has to work to get the gratification of recording a score.


This system will be developed further for MK2.
