Manipulating `phonfieldwork` data with `tidyverse`

Introduction

The output tables from the phonfieldwork's functions (e. g. textgrid_to_df(), eaf_to_df(), exb_to_df(), flextext_to_df() etc.) is hard to interpret since each row is a separate morpheme/observation or aother unit. In order to merge it to a more common representation we will use tidyverse functions (mainly dplyr and tidyr packages). This text will help you to achieve some results, but it is better to spend some times learning data manipulation with dplyr and tidyr.

If you do not have tidyverse installed run:

install.packages("tidyverse")

Let's load the package:

library("tidyverse")

.TextGrid, .eaf, .exb formats

The standard sound annotation formats consisnt of tiers with parallel annotation:

If we convert this file to R we will achieve something like this:

textgrid_to_df("s1/s1_all.TextGrid")
#> Error in file(file_name, encoding = readr::guess_encoding(file_name)$encoding): invalid 'encoding' argument

As we see this table has a long format structure: each observation has its own row. We can select the first two rows with the filter() function, remove all unnecessary columns with the select() function and spread everything in a table with the pivot_wider() function:

textgrid_to_df("s1/s1_all.TextGrid") %>% 
  filter(tier %in% 1:2) %>% 
  select(-time_start, -time_end, -tier_name) %>% 
  pivot_wider(names_from = tier, values_from = content)
#> Error in file(file_name, encoding = readr::guess_encoding(file_name)$encoding): invalid 'encoding' argument

.flextext format

Imagine that we obtained the first result from flextext_to_df():

df <- flextext_to_df("files/zilo_test.flextext")
#> It can take some time for big files...
head(df)
#>   p_id s_id w_id    txt     cf hn     gls                   msa                free_trans

As we can see from df print there are three indices in the dataset: p_id -- paragraph id, s_id -- sentence id and w_id -- word id.

df %>% 
  filter(free_trans != "") %>% 
  select(p_id, s_id, w_id, txt, gls, free_trans) %>% 
  group_by(p_id, s_id, free_trans, w_id) %>% 
  summarise(txt = str_c(txt, collapse = ""),
         gls = str_c(gls, collapse = "-"))

The first filter() removes some garbage rows that are present in our example flextext. The select() function selects only six important columns from 15 presented in the dataset. The group_by() and summarise() merge all text from txt variable and all glosses from gls variable together. Pipe operater %>% make it possible to pass the result from the previous funstion as an input to the following one.

So now we can use the same code in order to merge everything into sentences:

df %>% 
  filter(free_trans != "") %>% 
  select(p_id, s_id, w_id, txt, gls, free_trans) %>% 
  group_by(p_id, s_id, free_trans, w_id) %>% 
  summarise(txt = str_c(txt, collapse = ""),
         gls = str_c(gls, collapse = "-")) %>% 
  group_by(p_id, s_id, free_trans) %>% 
  summarise(txt = str_c(txt, collapse = " "),
         gls = str_c(gls, collapse = " "))
#> `summarise()` has grouped output by 'p_id', 's_id', 'free_trans'. You can override using
#> the `.groups` argument.

It is also very easy to get some simple statistics from the data:

df %>% 
  filter(gls != "") %>% 
  count(gls) %>% 
  top_n(6)
#> Selecting by n
#>        gls  n
#> 1     =add 46
#> 2       an 49
#> 3  cvb(pf) 63
#> 4      pst 28
#> 5 pst(aor) 74
#> 6     ¬an1 34

Here with the filter() function we remove all empty glosses, then we calculate and sort them according to frequency, and in the end we take top six glosses with the top_n() function. We can even visualis it with the ggplot2 package:

df %>% 
  filter(gls != "") %>% 
  count(gls) %>% 
  top_n(11) %>% 
  ggplot(aes(n, fct_reorder(gls, n)))+
  geom_col()+
  labs(x = "count", y = "gloss")
#> Selecting by n
