Harmony: Natural Language Processing Tool for Item Harmonisation is now on CRAN

We are excited to announce that Harmony, a Natural Language Processing tool for data harmonisation, is now available on the Comprehensive R Archive Network CRAN!

Previously, Harmony R could be installed using devtools.

Harmony can be used to compare questionnaire items across studies, find the best match for a set of items, and identify different versions of the same questionnaire. Harmony is a collaboration project between Ulster University, University College London, the Universidade Federal de Santa Maria, and Fast Data Science. It is funded by Wellcome as part of the Wellcome Data Prize in Mental Health.

To install Harmony, you can use the following command in your R console or R Studio:

install.packages("harmonydata")

We encourage you to try Harmony and let us know what you think! You can also follow us on Twitter @harmonydata for updates.

Are you excited to use Harmony to harmonize your instruments?

Here is a quick walkthrough on how to do it:

  1. Import the Harmony library:
library(harmonydata)
  1. Load the instruments from a file or URL:
instrument = load_instruments_from_file(path = "examples/GAD-7.pdf")
instrument_2 = load_instruments_from_file("https://medfam.umontreal.ca/wp-content/uploads/sites/16/GAD-7-fran%C3%A7ais.pdf") 
instruments = append(instrument, instrument_2)
  1. Match the instruments:
match = match_instruments(instruments)
  1. Get the results of the match:
names(match)
#> [1] "questions"        "matches"          "query_similarity"

As you can see, the match object contains a lot of information about the best match for each question in the query instrument. This information can be used to harmonise the instruments and make them more comparable.

We hope this walkthrough is helpful. Let us know if you have any other questions.

I’m so excited to see what you can do with Harmony!

Data Harmonisation Tools – Overview Organisations typically collect data from multiple sources and for many different reasons. This data comes in various forms and formats – for example, it may be coming from market research, customer research or inter-organisation departments. Data harmonisation, an advanced technique used to make sense of all the raw data collected and uses for research purposes, becomes necessary in this case, but unless it is incorporated effectively, organisations might miss the full, holistic view of business performance that they wish to gain.
