Option 1: Data is in a dataframe

The package comes with sample data. For this demonstration, we use dev_coop. The raw data looks like this:

We will look at question 11_3 (responses to ‘’Jatka lausetta: Maailman kolme suurinta ongelmaa ovat… (Avokysymys)’) as our open-ended survey question. We also want to include our survey weights (in ‘paino’ column) and bring in the gender and region columns so we can use these values to compare groups.

The main function here is fst_prepare()

# FUNCTION DEFINITION
fst_prepare <- function(data,
                        question,
                        id,
                        model = "ftb",
                        stopword_list = "nltk",
                        weights = NULL,
                        add_cols = NULL,
                        manual = FALSE,
                        manual_list = "")

We can run the function as follows:

df <- fst_prepare(data = dev_coop,
                  question = 'q11_3', 
                  id = 'fsd_id', 
                  weights = 'paino',
                  add_cols = c('gender', 'region')
                  )

Summary of components

• data is the dataframe of interest. In this case, we are using data that comes with the package called “dev_coop”.
• The question is the name of the column in your data which contains the open-ended survey question. In this example, we’re considering “q11_3”
• id is the id column in our data, which is “fsd_id”
• The function also requires a Finnish language model available for udpipe, in this case we are using the default Finnish Treebank, model = "ftb". (There are two options for Finnish language model; the other option is the Turku Dependency Treebank “tdt”.)
• By default we will remove stopwords from the “nltk” stopword_list in this example. (To find the relevant lists of Finnish stopwords, you can run the fst_find_stopwords() function.) Punctuation is also removed from the data whenever stopwords are removed.
• Optionally, you can add a weights column in your formatted data. Our weights are stored in the raw data as “paino”.
• Optionally, you can add other columns to your formatted data (for use in comparison functions). We include our “gender” and “region” columns for this reason
• The results in CoNLL-U format are stored in the local environment as df.
• (manual and manual_list are used if you want to provide your own list of stopwords to remove from the data.)

The formatted data looks like this:

Option 2: Data is in a svydesign object

The other option is to get your data from a svydesign object from the survey package. The survey package is a popular package used for analysing surveys.

The main function here is fst_prepare_svydesign()

# FUNCTION DEFINITION
fst_prepare_svydesign <- function(svydesign,
                                  question,
                                  id,
                                  model = "ftb",
                                  stopword_list = "nltk",
                                  use_weights = TRUE,
                                  add_cols = NULL,
                                  manual = FALSE,
                                  manual_list = "") 

We can run the function as follows:

df2 <- fst_prepare_svydesign(svydesign = svy_dev,
                            question = 'q11_3', 
                            id = 'fsd_id', 
                            use_weights = TRUE,
                            add_cols = c('gender', 'region')
                            )

The only differences between the previous function and this one are:

• svydesign is your svydesign object. In this case, we have one called “svy_dev”
• The svydesign object has a component called “prob” which contains the inverse of the weights. Therefore, we use these by setting use_weights = TRUE

The formatted data looks like this (should look very similar to the above formatted data!):

Summary Tables

First, let’s create some summaries using fst_summarise, fst_pos and fst_length_summary

These functions are defined as follows:

# FUNCTION DEFINITIONS
fst_summarise <- function(data, 
                          desc = "All respondents") 

fst_pos <- function(data) 
  
fst_length_summary <- function(data,
                               desc = "All respondents",
                               incl_sentences = TRUE) 

Summary of components

• data is the formatted data.
• desc is an optional name for the responses summarised, if not provided it will default to “All respondents”.
• incl_sentences is an optional boolean for whether to also summarise sentence length (in addition to word length), if not provided it will default to TRUE.

Hence, these functions are run for our sample data as follows:

fst_summarise(df)
