1 - Introduction ¶

Back to ToC¶

This Jupyter Notebook demonstrates how to display the syntax tree for a specific verse. We will begins by explaining how you can use Text-Fabric to select a particular verse from the Greek New Testament. Additionally, it utilizes the A.viewType() function to showcase the differences between the two types of syntax tree presentations included in the dataset.

3 - Performing the queries ¶

3.1 - Show a specific verse¶

The following example demonstrates a query for a specific verse (Mark 1:1). As expected, the query returns a single result.

The result stored in object VerseResult is a list of tuples. In this example, the list contains only one tuple. Each tuple corresponds to the nodes retrieved based on the query template, with the number of nodes in the tuple matching the three specified in the query.

You can inspect the contents of VerseResult using the following print statement:

print (VerseResult)

This will display the numeric values for the selected book, chapter, and verse nodes, which are in this example:

[(137781, 137835, 383782)]

Next we will print the syntax tree for the obtained results:

3.1.1 - Alternative methods ¶

In addition to the straightforward example provided earlier, there are other, more advanced methods for selecting a specific verse in Text-Fabric. In this section two will be briefly described.

Firstly, the code from the previous cells can be combined into a single, compact, and efficient line of code. This approach yields a list of tuples, with each tuple containing only one element (namely a verse node), which is then used as argument for the A.show() function:

N1904.show(N1904.search('verse book=Mark chapter=1 verse=1'))

Another method takes advantage of the fact that A.show() expects a list of tuples. This is achieved by encapsulating the numeric value of the verse node in a list, using square brackets [ ], and making the integer part of a tupe, using parentheses ( , ). Additionally, the function T.nodeFromSection() expects a tuple as input, which is created using ('Mark',1,1). Combining these steps results in the following construction:

N1904.show([(T.nodeFromSection(('Mark',1,1)), )])

3.2 - Selecting individual words of the verse ¶

A similar (but still different) result can be obtained by selecting all words from the verse individualy. Since each word is counted as a separate result, the total number of results is higher — in this case, seven. Additionally, note that the found items (i.e., individual words) are highlighted in yellow. Using the argument condensed=Truecombines all the found items, limiting the display to a single instance of the verse, as all results come from the same verse. If the argument condensed=False were supplied, the verse would be displayed seven times, with each instance highlighting the next consecutive word in yellow.

3.3 - Available text output formats ¶

Text-Fabric's data design enables a very flexible representation of the corpus text (see this section). If no specific format is defined, the default format will be used, which was set during the dataset's creation (for this dataset, the default is text-orig-full). Additionally, the dataset includes several other formats that are particularly relevant to the Greek New Testament corpus.

To view the available formats for displaying the text in this dataset:

This list reveals that all defined formats are based on word nodes. This means that the output for any given format is generated using a specific set of features associated with word nodes. The exact combination of features used for each text format can be examined by running the following command:

Remark regarding data origin¶

This data originates from file otext.tf:

@config
...
@fmt:text-orig-full={before}{text}{after}
...

3.4 - Compare text output formats ¶

Using the example verse, we can illustrate how the different formats in this dataset influence the presentation of Mark 1:1. To do this, we iterate over the defined text formats and display the text associated with the verse node in each format.
