1. Einleitung

Dieses Tutorial ist zum großen Teil eine Wiederholung und zu einem kleinen Teil ein Vorgriff auf noch kommende Tutorials.

In den folgenden Abschnitten werden wir alle nötigen Schritte einer Textanalyse durchgehen. Dafür verwenden wir natürlich das quanteda-Paket. Das Ziel dieses Tutorials ist es euch ein sicheres Verständnis zu vermitteln, welche Schritte bei einer Textanalyse tatsächlich gemacht werden müssen. Außerdem dienen die gewollten Wiederholen dazu, dass ihr sicherer und geübter im Umgang mit quanteda und der Textanalyse werdet.

2. quanteda

Das quanteda-Paket ist ein Textanalyse-Paket für R. Es deckt nahezu alles ab, was nötig ist, um eine Textanalyse durchzuführen. Natürlich bietet quanteda auch eine klare und umfangreiche Dokumentation und eine Vielzahl an Tutorials.

Wir werden uns in diesem Tutorial auf die wichtigsten Schritte zur Vorbereitung einer Textanalyse konzentrieren und lernen, wie man die quanteda-Dokumentation für die einzelnen Funktionen nutzt.

Der Pflichttext für diese Sitzung von Welbers, van Atteveldt und Benoit, 2017 bespricht ebenfalls alle Schritte, welche wir jetzt besprechen werden.

Zur Erinnerung: das quanteda-Paket und seine Nebenpakete müsst ihr beide jeder R-Sitzung laden, jedoch nur einmal vorher installieren:

#install.packages("quanteda.textplots")
#install.packages("quanteda.textstats")
# install.packages("quanteda") # Falls noch nicht geschehen, dann bitte installiert das Paket bitte. 

library(quanteda)
library(quanteda.textplots)
library(quanteda.textstats)

3. Textanalyse mit quanteda

Im folgenden werden wir die klassischen Schritte einer Textanalyse durchsprechen:

  1. Texte importieren und Korpus erstellen

  2. Dokumentenmatrix erstellen, bereinigen und filtern (Der wichtigste Teilschritt! Hier entscheidt sich die Güte der nachfolgenden Analyse)

  3. Analyse (Dieser Schritt wird nur kurz besprochen, da wir im Verlauf des Seminars einzelne Analysemethoden im Detail besprechen werden.)

3.1 Schritt 1: Texte importieren und Korpus erstellen

Der erste Schritt einer Textanalyse ist immer die zu analysierenden Texte in R einzulesen. Textdateien werden in einer Vielzahl von Formaten gespeichert: einfache txt-Files, csv-Dateien, html-Dateien und natürlich PDF. Erfahrungsgemäß machen einfache txt-Dateien die wenigsten Probleme. Eine Anleitung wie ihr txt-Dateien einlest findet ihr im zweiten Tutorial zu dieser Sitzung (Titel: "Erste Schritte mit quanteda"). Das Einlesen von Textdaten mit quanteda funktioniert am effizientesten mit dem readtext-Paket und dem readr-Paket.

# install.packages("readtext") # Falls noch nicht geschehen, dann bitte installiert das Paket bitte. 
# install.packages("readr")
# install.packages("tidyverse")

library(readtext)
library(readr)
library(tidyverse)

3.1.1 Texte aus CSV Dateien importieren

Der Einfachheit halber verwenden wir eine csv-Datei, die online verfügbar ist. Der Prozess des Einlesens der Daten ist identisch zu dem des Einlesens einer csv-Datei die ihr auf eurem Computer gespeichert habt (hier müsst ihr dann euren Computerpfad verwenden).

Die Datei die wir jetzt importieren beinhaltet die State of the Union-Reden der US-Präsidenten, wobei jedes Dokument (d.h. jede Zeile in der csv-Datei) ein Absatz einer Rede ist. Die Daten werden als ein data.frame importiert.

sotu_url <-  "https://bit.ly/2QoqUQS"
sotu_data <-  read_csv(sotu_url)
head(sotu_data)   ## view first 6 rows
## # A tibble: 6 x 5
##   paragraph date       President     Party text                                 
##       <dbl> <date>     <chr>         <chr> <chr>

## 6         6 1790-01-08 George Washi… Other There was reason to hope that the pa…

Jetzt können wir einen quanteda-Corpus mit der corpus-Funktion erstellen. Wie immer gilt: wenn ihr mehr über die Funktion und ihre Möglichkeiten erfahren wollt, dann nutzt die help-Page --> ?corpus.

Für unser Beispiel müssen wir quanteda informieren, dass wir einen data.frame verwenden und welche Spalte des Datensatzes das Textfeld enthält:

sotu_corpus <-  corpus(sotu_data, text_field = "text")  
sotu_corpus
## Corpus consisting of 23,469 documents and 4 docvars.
## text1 :
## "I embrace with great satisfaction the opportunity which now ..."
## 
## text2 :
## "In resuming your consultations for the general good you can ..."
## 
## text3 :
## "Among the many interesting objects which will engage your at..."
## 
## text4 :
## "A free people ought not only to be armed, but disciplined; t..."

## 
## text6 :
## "There was reason to hope that the pacific measures adopted w..."

3.1.2 Texte aus Word und PDF-Dateien importieren

Anstelle einer csv-Datei ist es natürlich auch möglich weitere Dateiformate zu importieren. Zum Beispiel txt-, .pdf- oder .docx-Dateien.

url <-  "https://github.com/phimeyer/phimeyer.github.io/raw/master/_teaching/files.zip"
texts <-  readtext(url)
texts
## readtext object consisting of 2 documents and 0 docvars.
## # Description: df[,2] [2 × 2]
##   doc_id        text               
##   <chr>         <chr>              
## 1 document.docx "\"This is a \"..."
## 2 pdf_file.pdf  "\"This is a \"..."

Wie ihr steht, wurden die Dateien automatisch heruntergeladen, entpackt und in einfachen Text umgewandelt.

Wir können Texte natürlich auch von unserer lokalen Festplatte lesen (das ist in den meisten Fällen auch der "normale" Weg, da wir ja zu erst die Dokumente herunterladen). Hierfür müssen wir lediglich den Pfad angeben:

texts <-  readtext("c:/pfad/zu/unseren/dateien")
texts <-  readtext("/Benutzer/ich/Dokumente/dateien")

3.2 Schritt 2: Erstellen einer DTM (oder DFM)

Die meisten Textanalysen basieren auf den Häufigkeiten von Wörtern in Dokumenten. Das wird als Bag-of-Words-Annahme bezeichnet: die Texte sind die Säcke in denen einzelne Wörter stecken. Interpunktion, Wortreihenfolge, Füllwörter und einzelne häufig vorkommende Wörter werden in diesem Vorgehen bereits in den ersten Schritten gelöscht. Obwohl dadurch viele relevante Informationen ignoriert werden, hat sich dieser Ansatz als leistungsfähig und effizient erwiesen.

Das Standardformat für die Darstellung eines Bag-of-Words ist eine Dokument-Term-Matrix (DTM). Hierbei handelt es sich um eine Matrix, in der Zeilen Dokumente sind und die Spalten Wörter repräsentieren. Wir werden zunächst eine kleine Beispiel-DTM aus ein paar Zeilen Text erstellen. Hier verwenden wir die tokens-Funktion und die dfm-Funktion von quanteda. dfm steht für Document-Feature-Matrix:

text <-  c(d1 = "Die Leibniz Universität Hannover macht gute Lehre.",
           d2 = "Mit mehr Katzen wäre die Lehre noch besser!",
           d3 = "Warum denn eine Katze? Ein Hund ist viel zutraulicher.",
           d4 = "Wir wollen viele Katzen!")

text_tokens <- tokens(text)
dtm <- dfm(text_tokens)
dtm
## Document-feature matrix of: 4 documents, 28 features (70.54% sparse) and 0 docvars.
##     features
## docs die leibniz universität hannover macht gute lehre . mit mehr
##   d1   1       1           1        1     1    1     1 1   0    0
##   d2   1       0           0        0     0    0     1 0   1    1
##   d3   0       0           0        0     0    0     0 1   0    0
##   d4   0       0           0        0     0    0     0 0   0    0
## [ reached max_nfeat ... 18 more features ]

Mit diesem Matrixformat können wir jetzt Analysen durchführen, wie z. B. die Analyse verschiedener Frames in Bezug auf Katzen, oder die Berechnung der Ähnlichkeit zwischen dem dritten Satz und den ersten beiden Sätzen.

3.2.1 Das sogenannte pre-processing: die DFM aufarbeiten und bereinigen

Die direkte Umwandlung eines Textes in einen DFM ist sehr vereinfachend. Beachtet z. B., dass die Wörter "Katzen" und "Katze" unterschiedliche Spalten erhalten. Außerdem sind "Hannover" und "Lehre" genauso unterschiedlich wie "Katzen" und "Katze". Das ist ein Problem, vor allem da wir eher an der Tatsache interessiert sind, dass es in den Sätzen um Katzen geht und weniger um das spezifische Wort an sich. Wir wollen also den Inhalt analysieren. Weiterhin sind Textanalysen vor allem dann aussagekräftig, wenn weniger interessante Wörter wie "die" oder selte Wörter wie "Universität" ignoriert werden.

Um das zu erreichen, müssen wir zusätzliche Verarbeitungsschritte einfügen. Im nächsten Bespiel erstellen wir eine DFM. Vorher konvertieren wir die Texte in tokens und transformieren dabei alle Buchstaben zu Kleinbuchstaben, ignorieren Füllwörter (tokens_remove(pattern = stopwords("de"))) und die Interpunktion.

Zusätzlich erstellen wir eine zweite DFM mit unseren State-of-the-Union-Reden (siehe oben) und führen dort zusätzlich ein Stemming durch (stemming fünktioniert mit der deutschen Sprache weniger gut, weshalb unsere Beispielsätze hierfür nicht geeignet sind). Einfach ausgedrückt, werden beim Stemming Wörter auf ihren Wortstamm reduziert. Dadurch werden einige Teile an den Wortenden entfernt und so verschiedene Formen desselben Wortes ignoriert. Zum Beispiel Singular versus Plural ("gun" oder "gun-s") und verschiedene Verbformen ("walk", "walk-ing", "walk-s").

# Beispiel 1: Unsere drei Sätze  
text_tokens <- tokens(text, remove_punct=T) %>% 
  tokens_remove(pattern = stopwords("de")) %>%
  tokens_tolower()

Das tokens_tolower-Argument bestimmt, ob Texte in Kleinbuchstaben umgewandelt werden oder nicht. tokens_wordstem bestimmt, ob Stemming verwendet wird oder nicht.

Ihr müsst die Befehle übrigens nicht als Pipeline (%>%) schreiben. Alternativ könnt ihr die Funktionen auch einzeln ausführen (und dabei das jeweilige Objekt immer wieder einzeln ansteuern):

sotu_tokens <- tokens(sotu_corpus, remove_punct=T) 
sotu_tokens <-  tokens_remove(sotu_tokens, pattern = stopwords("en")) 
sotu_tokens <-  tokens_tolower(sotu_tokens) 
sotu_tokens <-  tokens_wordstem(sotu_tokens)
sotu_dfm <-  dfm(sotu_tokens)

Die tokens_remove-Funktion ist etwas kniffliger. Wenn ihr einen Blick in die Dokumentation der Funktionen (?) werft, werdet ihr sehen, dass remove verwendet werden kann, um bestimmte benutzerinnendefinierte Merkmale bzw. Muster zu ignorieren. In diesem Fall haben wir tatsächlich eine andere Funktion, stopwords(), verwendet, um eine Liste von Füllwörtern zu entfernen.

Diese Wortliste wird an das remove-Argument in dfm() übergeben, um so diese Wörter zu ignorieren.

Es gibt weitere Techniken zum pre-processing. Für weitere Details lest den Text von Welbers, van Atteveldt und Benoit, 2017.

3.2.2 Eine DFM filtern

Unsere DFM mit den Reden zur Lage der Nation hat 23.469 Dokumente und 20.429 Merkmale (d. h. Terme/Wörter). Abhängig von der Art der Analyse, die wir durchführen wollen, benötigen wir vielleicht nicht so viele Wörter. Glücklicherweise sind viele dieser 20.000-Merkmale nicht so informativ. Das Entfernen der nicht informativen Wörter wird unsere Ergebnisse verbessern.

Wir können die Funktion dfm_trim verwenden, um bestimmte Wörter zu entfernen. Im Beispiel definieren wir, dass wir alle Wörter entfernen wollen die weniger als 10 Mal vorkommen (d. h. der Summenwert der Spalte im DFM).

dtm  <-  dfm_trim(sotu_dfm, min_termfreq = 10)
dtm
## Document-feature matrix of: 23,469 documents, 5,299 features (99.36% sparse) and 4 docvars.

Jetzt haben wir also nur noch rund 5.000 Wörter übrig. Schat euch ?dfm_trim für mehr Infos und Optionen zum filtern an!

3.3 Analyse

Ein paar Analysemethoden habt ihr bereits kennengelernt. Zur Wiederholung werde ich diese und weitere noch einmal kurz vorstellen.

3.3.1 Worthäufigkeiten und Wordclouds

Schauen wir uns die häufigsten Wörter im Korpus mittels einer wordcloud an:

textplot_wordcloud(sotu_dfm, max_words = 50)     # top 50 wörter

textplot_wordcloud(sotu_dfm, max_words = 50, color = c('blue','red')) # farben verändern

textstat_frequency(sotu_dfm, n = 10)             # häufigkeiten
##     feature frequency rank docfreq group
## 1     state      9234    1    5580   all
## 2    govern      8581    2    5553   all
## 3      year      7250    3    4934   all
## 4    nation      6733    4    4847   all
## 5  congress      5689    5    4494   all
## 6      unit      5223    6    3715   all
## 7       can      4731    7    3628   all
## 8   countri      4664    8    3612   all
## 9     peopl      4477    9    3388   all
## 10     upon      4168   10    3004   all

Wir können auch nur Teile von unserem Korpus untersuchen. Zum Beispiel, indem man nur die Obama-Reden betrachtet. Um eine DFM zu subsetten/zu zerteilen, nutzen wir die dtm_subset-Funktion.

Mit docvars(dtm) erhalten wir einen data.frame mit den Dokumentvariablen. Mit docvars(dtm)$Präsident erhalten wir den Zeichenvektor mit den Namen der Präsidenten. Mit docvars(dtm)$Präsident == 'Barack Obama' suchen wir nach allen Dokumenten, in denen der Präsident Obama war. Um dies zu verdeutlichen, speichern wir den logischen Vektor, der anzeigt, welche Dokumente 'TRUE' sind, als is_obama. Diesen verwenden wir dann, um diese Zeilen aus dem DFM auszuwählen.

is_obama <-  docvars(sotu_dfm)$President == 'Barack Obama' 
obama_dtm <-  sotu_dfm[is_obama,]
textplot_wordcloud(obama_dtm) # diesmal ohne eine max_words einschränkung

3.3.2 Korpora vergleichen

Hier verwenden wir (wieder) einen Vergleich, um den is_obama-Vektor zu erhalten. Diesen verwenden wir dann in der Funktion textstat_keyness, um anzugeben, dass wir die Obama-Dokumente (bei denen is_obama TRUE ist) mit allen anderen Dokumenten (bei denen is_obama FALSE ist) vergleichen wollen.

is_obama <-  docvars(sotu_dfm)$President == 'Barack Obama' 
sotus_obama_all <-  textstat_keyness(sotu_dfm, is_obama)
head(sotus_obama_all, 20)    ## view first 20 results

Unsere Ergebnisse können wir mit der Funktion textplot_keyness visualisieren:

textplot_keyness(sotus_obama_all)

3.3.3 Key-word-in-Context

Ein Keyword-in-Context-Listing zeigt ein bestimmtes Keyword im Kontext seiner Verwendung. Generell ist das eine gute Methode einen Korpus kennenzulernen. Da ein DFM nur Worthäufigkeiten kennt, benötigen wir für die kwic-Funktion das Korpusobjekt.

sotu_tokens <- tokens(sotu_corpus) 
sotus_kwic <- kwic(sotu_tokens, 'freedom', window = 5)
head(sotu_corpus, 10)    ## only view first 10 results
## Corpus consisting of 10 documents and 4 docvars.
## text1 :
## "I embrace with great satisfaction the opportunity which now ..."
## 
## text2 :
## "In resuming your consultations for the general good you can ..."
## 
## text3 :
## "Among the many interesting objects which will engage your at..."
## 
## text4 :
## "A free people ought not only to be armed, but disciplined; t..."
## 
## text5 :
## "The proper establishment of the troops which may be deemed i..."
## 
## text6 :
## "There was reason to hope that the pacific measures adopted w..."
## 
## [ reached max_ndoc ... 4 more documents ]

Die kwic-Funktion kann auch verwendet werden, um eine Analyse auf einen bestimmten Suchbegriff zu fokussieren. Wir können die Ausgabe der Funktion verwenden, um eine neue DFM zu erstellen, damit nur die Wörter innerhalb des angezeigten Fensters in die Matrix aufgenommen werden. Mit dem folgenden Code wird ein DFM erstellt, die nur die Wörter enthält, die innerhalb von 10 Wörtern vor oder nach dem Begriff terror* (terrorism, terrorist, terror, etc.) vorkommen:

sotus_terror <-  kwic(sotu_tokens, 'terror*')

sotus_terror_corp <-  corpus(sotus_terror)

sotus_terror_tokens <- tokens(sotus_terror_corp, remove_punct=T) %>% 
  tokens_remove(pattern = stopwords("en")) %>% 
  tokens_tolower() %>%
  tokens_wordstem()

sotus_terror_dtm <-  dfm(sotus_terror_tokens)

textplot_wordcloud(sotus_terror_dtm)  

Wie würde diese Kette von Befehlen in einer Pipeline aussehen? Probiert es mal aus!

3.3.4 Wörterbücher

Wir können mit quanteda ganz einfach eine Wörterbuchsuche/-analyse durchführen. In Sitzung 6 werden wir noch genauer darauf eingehen. Aus diesem Grund werde ich euch im folgenden Beispiel zeigen, wie man bereits bei der Erstellung einer DFM Wörterbuchbegriffe einbaut. Vergesst bitte nicht, dass Wörterbücher nur dann aussagekräftig sind, wenn sie theoriegeleitet erstellt und auf ihre Validität hin überprüft wurden.

sotu_tokens <- tokens(sotu_corpus, remove_punct=T) %>% 
  tokens_remove(pattern = stopwords("en")) %>% 
  tokens_tolower() # zu Präsentationszwecken ohne Stemming
  
sotu_dfm <-  dfm(sotu_tokens)
sotu_dfm

sotus_dict <-  dictionary(list(terrorism = c("terror*", "bomb*","violence"),
                               economy = c("economy", "tax", "job"),
                               military = c("army","navy","milit*","airforce","soldier*"),
                               freedom = c("freedom","liberty", "democra*")))

## [ reached max_ndoc ... 23,463 more documents ]

Auf dieser Grundlage können wir jetzt unsere Analysen durchführen.

keyness_obama <-  textstat_keyness(sotus_dict_dtm, docvars(sotus_dict_dtm)$President == "Barack Obama")

textplot_keyness(keyness_obama)

Wie ihr unschwer erkennen könnt: dieses Wörterbuch ist nicht sehr aussagekräftig. Aber das ist nicht weiter schlimm, hier geht es ja lediglich um den Zweck der Präsentation.

Wir können die DFM auch in einen Datensatz konvertieren, und erhalten dann die Anzahl der einzelnen Konzepte pro Dokument (die man dann z. B. mit Umfragedaten abgleichen könnte).

sotus_dict_df <-  convert(sotus_dict_dtm, to="data.frame")
head(sotus_dict_df)
##   doc_id terrorism economy military freedom
## 1  text1         0       0        0       0
## 2  text2         0       0        0       0
## 3  text3         0       0        0       0
## 4  text4         0       0        1       0
## 5  text5         0       1        1       0
## 6  text6         0       0        0       0

3.3.5 Die Gültigkeit von Wörterbüchern testen

Ein gutes Wörterbuch bedeutet, dass alle Dokumente, die mit dem Wörterbuch übereinstimmen, tatsächlich von dem gewünschten Konzept handeln oder dieses enthalten.

Um das zu überprüfen, können wir eine Stichprobe von Dokumenten manuell kodieren und die Ergebnisse mit den Treffern im Wörterbuch vergleichen. Dazu mehr in Sitzung 6!
