# ICC aims & charcteristics

* make available comparable corpora  of many languages for contrastive linguistic research [@kirk_ice_2017]
* mostly based on existing corpora
* ICC has a pre-defined “balanced” composition
  * based on the one of the ICE [@greenbaum_comparing_1996]

# Current launch of ICC written

* written parts for Chinese, Czech, English, German, Irish (partly), Norwegian publicly available
  * partially including UDPipe 2.0 annotations [@straka_udpipe_2018]
  * via Corpus Workbench or KorAP [@diewald_korap_2016]
  
  * usable via Corpus Workbench or KorAP [@diewald_korap_2016]

## Composition of the ICC parts 

```{r composition-by-genre, fig.cap="Actual composition of selected ICC parts with respect to ICC domain. (For the other ICC parts, the ICC genre metadatum was not yet accessible via the API at the editorial deadline.)", message = FALSE, fig.width=14, fig.height=10, out.width = "100%"}

  expand_grid(genre) %>%
  mutate(vc = paste0("iccGenre=", genre)) %>%
  rowwise() %>%
  mutate(tokens= corpusStats(icc_con(lang, token), vc = vc)@tokens)

icc_genre %>% ggplot(aes(x=lang, fill=genre, y=tokens)) +
  geom_col() + scale_y_continuous(labels = label_number(scale_cut = cut_short_scale())) +

```


```{r composition-by-pubdate, fig.cap="Composition of the selected ICC parts with respect to year of publication.", message=F, warning=F, fig.width=14, fig.height=3, out.width = "80%"}

# Pilot study

* Identification of Light Verb Constructions with *take*
* in order to investigate the limitations imposed by the very small corpus sizes
* using RKorapClient [@kupietz_rkorapclient_2020] to access corpora and get reproducible results of the collocation analysis


```{r take-icc-code, results='hide', echo=TRUE}
library(RKorAPClient)
new("KorAPConnection", 
    KorAPUrl = "https://korap.ids-mannheim.de/instance/icc/eng",
    accessToken = Sys.getenv("KORAP_ICC_TOKEN_eng")) %>%
collocationAnalysis(
    "focus({[ud/l=take]} [ud/p=NOUN])",
    leftContextSize = 0,
    rightContextSize = 1,
    minOccur = 2,
    addExamples = T
)
```

```{r take-icc, fig.cap="R code and results of a co-occurrence analysis of *take* + NOUN in ICC-ENG, using the RKorAPClient package for R."}
take_ca_icc <-
  collocationAnalysis(
    icc_con("eng"),
    "focus({[ud/l=take]} [ud/p=NOUN])",
    leftContextSize = 0,
    rightContextSize = 1,
    minOccur = 2,
    addExamples = T
  )

take_ca_icc %>% show_table()
```

## Results

* for English the query for *take* + NOUN (as direct right neighbour) yields 10 different pairs with a minimum frequency of 2 (see  Figure \@ref(fig:take-icc))
  * based on English Wikipedia [2015 snapshot, see @MargarethaLuengen2014] the query yields 139 pairs (log-dice-threshold: 2.0) with 44 false positives

# Summary & Outlook

* we have made available corpora of 4+ languages available for contrastive research
* however, even with quite frequent phenomena, the results on the small corpora are to be used with caution
  * typically they need to be verified on larger monolingual corpora
* the uniform acces is in any case helpful for contrastive studies
* ICC also serves as a crystallization point for larger corpora and complementary approaches such as EuReCo
