Wilhelm Vocabulary ================== ![GitHub workflow status badge][GitHub workflow status] [![Apache License Badge]](https://www.apache.org/licenses/LICENSE-2.0) Data Format ----------- The data that serves [wilhelmlang.com](https://wilhelmlang.com/). They are written in YAML format, because 1. it is machine-readable so that it can be consumed quickly in data pipelines 2. it is human-readable and, thus, easy to modify 3. it supports multi-lines value which is very handy for data of natural languages How Data (Vocabulary) is Stored in a Graph Database --------------------------------------------------- ### Why Graph Database Graph data representation assumes universal connectivity among world entities. This applies pretty well to the realm of languages. Multilanguage learners have already seen that Indo-European languages are similar in many different ways. The similarities not only signify the historical facts about Philology but also surface a great opportunity for multilanguage learners to study much more efficiently. What's missing is connecting the dots using Graph Databases that visually presents these vastly enlightening links between the related languages. ### Definition _The meaning of a word is called the `definition`_. A term has a natural relationship to its definition(s). For example, the German noun ["Ecke"](https://en.wiktionary.org/wiki/Ecke#Noun) has at least 4 definitions: ![Relationship between term and defintion(s)](./definition.png "Error loading definition.png")

[German](./german.yaml) ----------------------- ### YAML Schema ```yaml vocabulary: - term: string definition: list declension/conjugation: application-specific table ``` - The `conjugation` is the inflection paradigm for a German verb and `declension` the inflection for nouns and adjectives. Only one of the two is present for a term. - The type of the word can be inferred using the following rule - `term` with a _definite article_ of __der__/__die__/__das__ signifies a __noun__. For instance ```yaml - term: die Wissenschaft definition: the Science ``` - Those with `conjugation` field denotes a __verb__; its definition also begins with an _indefinite form_, i.e. "to ..." - The rests are explicitly stated in the `definition` field. For example, ```yaml - term: ob definition: - (conj.) if - (conj.) whether ``` means "ob" is a **conjunction** in this case and ```yaml - term: denn definition: - (adv.) then, thus - (conj.) because ``` tells that "denn" can be __adverb__ or __conjunction__ > [!TIP] > > The parenthesized value at the beginning of each `definition` item played an un-ignorable role: it is the label of the > relationship between `term` and `definition` in graph database loaded by > [Wilhelm SDK](https://github.com/QubitPi/wilhelm-graphdb-python). For example, both German words > > ```yaml > - term: denn > definition: > - (adv.) then, thus > - (conj.) because > ``` > > and > > ```yaml > - term: nämlich > definition: > - (adj.) same > - (adv.) namely > - (adv.) because > ``` > > can mean "because" acting as different types. This is visualized as follows: > > ![error loading example.png](./example.png) > > __Visualzing synonyms this way presents a big advantage to human brain__ who is exceedingly good at memorizing > patterns ### German Noun Declension The declension table employees an [application-specific YAML](https://stackoverflow.com/q/30894438/14312712) that looks like the following: ```yaml - term: ein definition: (article) a, an declension: - ["", masculine, feminine, neuter, plural] - [nominative, ein, eine, ein, N/A ] - [genitive, eines, einer, eines, N/A ] - [dative, einem, einer, einem, N/A ] - [accusative, einen, eine, ein, N/A ] ``` The declension table above is equivalent to | | masculine | feminine | neuter | plural | |:--------------:|:---------:|:--------:|:------:|:------:| | __nominative__ | ein | eine | ein | N/A | | __genitive__ | eines | einer | eines | N/A | | __dative__ | einem | einer | einem | N/A | | __accusative__ | einen | eine | ein | N/A | > [!NOTE] > > - A list under `declension` is a table row > - All rows have the same number of columns > - Each element of the list corresponds to a table cell > [!TIP] > > __The declension tables for all nouns are sourced from > [Wiktionary](https://en.wiktionary.org/wiki/ein#Declension_2)__ ### German (Attributive) Adjective Declension > [!TIP] > > - Predicate adjectives (e.g. kalt in mir ist kalt "I am _cold_") are undeclined > - An adjective can both be predicative (a _brave_ boy) or attributive (The boy is _brave_). Only attributive > adjectives are declined. There are 3 types of declensions for German adjectives 1. [strong declension](https://en.wikipedia.org/wiki/German_declension#Strong_inflection), 2. [week declension](https://en.wikipedia.org/wiki/German_declension#Weak_inflection), and 3. [mixed declension](https://en.wikipedia.org/wiki/German_declension#Mixed_inflection) Each type bears a separate declension table. __To master German adjectives, we will need to memorize all of the three__. There is also [adjective comparison](https://en.wikipedia.org/wiki/German_adjectives#Adjective_comparison) which throws in potentially 6 more tables. But the [rules for comparative and superlative forms are quite universal](https://www.reddit.com/r/German/comments/i5mfrq/how_do_you_remember_adjective_declension/) so we __ignore the two and focus only on the positive form__, which is the basic form of the adjective. Here is an example of the adjective declension used in this repository: ```yaml - term: unterschiedlich definition: (adj.) different declension: - strong declension (without article): - ["", singular, singular, singular, plural ] - ["", masculine, feminine, neuter, "" ] - [nominative, unterschiedlicher, unterschiedliche, unterschiedliches, unterschiedliche ] - [genitive, unterschiedlichen, unterschiedlicher, unterschiedlichen, unterschiedlicher] - [dative, unterschiedlichem, unterschiedlicher, unterschiedlichem, unterschiedlichen] - [accusative, unterschiedlichen, unterschiedliche, unterschiedliches, unterschiedliche ] - weak declension (with definite article): - ["", singular, singular, singular, plural ] - ["", masculine, feminine, neuter, "" ] - [nominative, der unterschiedliche, die unterschiedliche, das unterschiedliche, die unterschiedlichen] - [genitive, des unterschiedlichen, der unterschiedlichen, des unterschiedlichen, der unterschiedlichen] - [dative, dem unterschiedlichen, der unterschiedlichen, dem unterschiedlichen, den unterschiedlichen] - [accusative, den unterschiedlichen, die unterschiedliche, das unterschiedliche, die unterschiedlichen] - mixed declension (with indefinite article): - ["", singular, singular, singular, plural ] - ["", masculine, feminine, neuter, "" ] - [nominative, ein unterschiedlicher, eine unterschiedliche, ein unterschiedliches, (keine) unterschiedlichen ] - [genitive, eines unterschiedlichen, einer unterschiedlichen, eines unterschiedlichen, (keiner) unterschiedlichen] - [dative, einem unterschiedlichen, einer unterschiedlichen, einem unterschiedlichen, (keinen) unterschiedlichen] - [accusative, einen unterschiedlichen, eine unterschiedliche, ein unterschiedliches, (keine) unterschiedlichen ] ``` > [!TIP] > > __The declension tables for all adjectives are sourced from > [Wiktionary](https://en.wiktionary.org/wiki/unterschiedlich#Declension)__ ### German Verb Conjugation There are __3__ persons, __2__ numbers, and __4__ moods (indicative, conditional, imperative and subjunctive) to consider in conjugation. There are __6__ tenses in German: the present and past are conjugated, and there are four compound tenses. There are two categories of verbs in German: [weak and strong](https://en.wikipedia.org/wiki/Germanic_strong_verb)[^1]. In addition, [strong verbs are grouped into 7 "classes"](https://en.wikipedia.org/wiki/Germanic_strong_verb#Strong_verb_classes) [^1]: https://en.wikipedia.org/wiki/German_verbs#Conjugation The conjugation table of German verb on Wiktionary is hard to interpret for German beginner. It does, however, presents a very good Philology reference. For example, it tells us which of the 7 "classes" a strong verb belongs to. __We, therefore, leave the Wiktionary links to the conjugation table of that verb for data processing in the future__, for example, ```yaml - term: aufwachsen definition: to grow up conjugation: https://en.wiktionary.org/wiki/aufwachsen#Conjugation ``` and advise user to employ a much more practical method to learn daily conjugation as follows. We take "__aufwachsen__" as an example. > [!IMPORTANT] > I'm not advertising for any organizations. I'm simply sharing good resources. [Netzverb Dictionary](https://www.verbformen.com/) is the best German dictionary _targeting the vocabulary inflections_. [Search for "aufwachsen"](https://www.verbformen.com/?w=aufwachsen) and we will see much more intuitive conjugation tables listed. This pretty much serves our needs, but what makes Netzverb unpenetrable by other alternatives is that _every_ verb comes with 1. [A printable version that looks much better than the browser's Control+P export](https://www.verbformen.com/conjugation/aufwachsen.pdf) - There is also a "Sentences with German verb aufwachsen" section with a [link](https://www.verbformen.com/conjugation/examples/aufwachsen.htm) that offer a fruitful number of conjugated examples getting us familiar with the inflections of the verb 2.

This is why we left the conjugation link to Wiktionary for now and it will definitely serve us well as I'm > trying to make it happen [Ancient Greek](./greek.yaml) ----------------------------- ```yaml vocabulary: - term: string definition: list ``` [Wiktionary is the best source for Attic pronunciation](https://en.wiktionary.org/wiki/%CE%B1%E1%BD%90%CF%84%CF%8C%CF%82#Pronunciation), although [some words are missing the audio](https://en.wiktionary.org/wiki/%CE%BA%CE%B1%CE%AF#Pronunciation).
