Wilhelm Vocabulary

Data Format

The data that serves wilhelmlang.com. They are written in YAML format, because

it is machine-readable so that it can be consumed quickly in data pipelines
it is human-readable and, thus, easy to read and modify
it supports multi-lines value which is very handy for language data

Encoding Table in YAML

To encode the inflections which are common in most Indo-European languages, an application-specific YAML that looks like the following are employed throughout this repository:

  - term: der Gegenstand
    definition:
      - object
      - thing
    declension:
      - ["",         singular,                    plural      ]
      - [nominative, Gegenstand,                  Gegenstände ]
      - [genitive,   "Gegenstandes, Gegenstands", Gegenstände ]
      - [dative,     Gegenstand,                  Gegenständen]
      - [accusative, Gegenstand,                  Gegenstände ]

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

The declension (inflection) table above is equivalent to

	singular	plural
nominative	Gegenstand	Gegenstände
genitive	Gegenstandes, Gegenstands	Gegenstände
dative	Gegenstand	Gegenständen
accusative	Gegenstand	Gegenstände

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 aspects. The similarities not only signify the historical facts about Philology but also surface a great opportunity for multilanguage learners to take advantages of them and 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 in a natural way.

Base Schema

vocabulary:
  - term: string
    definition: list

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" has at least 4 definitions:

Graph data generated by wilhelm-python-sdk

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. For example, both German words
- term: denn
  definition:
    - (adv.) then, thus
    - (conj.) because
and
 - term: nämlich
   definition:
     - (adj.) same
     - (adv.) namely
     - (adv.) because
can mean "because" acting as different types. This is visualized as follows:

Visualzing synonyms this way presents a big advantage to human brain who is exceedingly good at memorizing patterns

Noun Declension

Declension is the inflection for nouns and adjectives.

The declension tables for all nouns are sourced from Wiktionary

Declension Template

term with a definite article of der signifies a masculine noun which has a declension table template of the following form:

declension:
  - ["",         singular, plural]
  - ["",         noun,     noun  ]
  - [nominative, ████████, ██████]
  - [genitive,   ████████, ██████]
  - [dative,     ████████, ██████]
  - [accusative, ████████, ██████]

For example:

  - term: das Getränk
    definition: the drink
    declension:
      - ["",         singular,            plural   ]
      - [nominative, Getränk,             Getränke ]
      - [genitive,   Getränkes, Getränks, Getränke ]
      - [dative,     Getränk,             Getränken]
      - [accusative, Getränk,             Getränke ]

Adjectival nouns, however, do NOT follow the template above.

Ancient Greek

Unless otherwise mentioned, we are talking about Attic Greek throughout this repository.

Diacritic Mark Convention

We employ the following 3 diacritic signs only in vocabulary:

the acute (ά)
the circumflex (ᾶ), and
the grave (ὰ)

In fact, it is called the medium diacritics and the same convention used in Loeb Classical Library prints from Harvard. Notice that, however, the commonly sourced Wiktionary uses full diacritics, including the breve diacritic mark; we don't do that.

Noun Declension

The vocabulary entry for each noun consists of its nominative and genitive forms, an article which indicates the noun's gender, and the English meaning. For example.

  - term: τέχνη τέχνης, ἡ
    definition:
      - art,
      - skill,
      - craft
    declension class: 1st

the vocabulary entry above consists of the following 4 items:

τέχνη: nominative singular
τέχνης: genitive singular
ἡ: nominative feminine singular of the article, which shows that the gender of the noun is feminine. Gender will be indicated by the appropriate form of the definite article "the":
- ὁ for the masculine nouns
- ἡ for the feminine nouns
- τό for the neutor nouns
a list of English meanings of the word

the noun employs the first declension. The 3 classes of declensions are

first declension (1st)
second declension (2nd)
third declension (3rd)

A multi-form nouns will have a list for this field. For example

  - term: αὐτός αὐτή αὐτό
    definition:
      - (without article) he, she, it, they
      - (without article) himself, herself, itself, themselves
      - (with definite article) same
    declension class:
      αὐτός: 2nd
      αὐτή: 1st
      αὐτό: 2nd

The declension of the entry is not shown because to decline any noun, we can take the genitive singular, remove the genitive singular ending to get the stem, and then add the proper set of endings to the stem based on its declension class[^2].

[^2]: Greek: An Intensive Course, 2nd Revised Edition, Hansen & Quinn, p.20

For example, to decline τέχνη τέχνης, ἡ, art, take the genitive singular τέχνης, remove the genitive singular ending -ης, and add the appropriate endings to the stem which gives following paradigm:

Case	Singular	Plural
nominative	τέχνη	τέχναι
genitive	τέχνης	τεχνῶν
dative	τέχνῃ	τέχναις
accusative	τέχνην	τέχνᾱς
vocative	τέχνη	τέχναι

Adjective Declension

Declension template:

declension:
  - ["",         singular,  singular, singular, dual,      dual,     dual    plural,    plural,   plural]
  - ["",         masculine, feminine, neuter,   masculine, feminine, neuter, masculine, feminine, neuter]
  - [nominative, █████████, ████████, ████████, █████████, ████████, ██████, █████████, ████████, ██████]
  - [genitive,   █████████, ████████, ████████, █████████, ████████, ██████, █████████, ████████, ██████]
  - [dative,     █████████, ████████, ████████, █████████, ████████, ██████, █████████, ████████, ██████]
  - [accusative, █████████, ████████, ████████, █████████, ████████, ██████, █████████, ████████, ██████]
  - [vocative,   █████████, ████████, ████████, █████████, ████████, ██████, █████████, ████████, ██████]

Verb Conjugation

The Greek verb has 6 principal parts. All 6 must be learned whenever a new verb is encountered:

(first person singular) present indicative active
(first person singular) future indicative active
(first person singular) aorist indicative active
(first person singular) perfect indicative active
(first person singular) perfect indicative passive
(first person singular) aorist indicative passive

The minimum number of forms which one must know in order to generate all possible forms of a verb are called the principal parts of that verb.

From the 6 forms above, various verb forms (i.e. stems & endings) can be derived by rules[^4]

[^4]: Greek: An Intensive Course, 2nd Revised Edition, Hansen & Quinn, p.44

In practice, however, obtaining precise and complete principal parts for some verbs has been proven to be impossible. While the best efforts have been made for reconstructing the complete principal parts, we also put a link to the Wiktionary of each verb for wilhelm-python-sdk, which will dynamically load the complete conjugation tables into graph database.

What's also being loaded are the reconstructed principal parts with a list of references that validate the reconstruction.

In conclusion, the entry of a verb, thus, has the form of:

- term: string
  definition: list
  conjugation:
    wiktionary: string
    principal parts:
      - ["",                                                 Attic, (Possibly other dialects)]
      - [(first person singular) present indicative active,  █████, ...                      ]
      - [(first person singular) future indicative active,   █████, ...                      ]
      - [(first person singular) aorist indicative active,   █████, ...                      ]
      - [(first person singular) perfect indicative active,  █████, ...                      ]
      - [(first person singular) perfect indicative passive, █████, ...                      ]
      - [(first person singular) aorist indicative passive,  █████, ...                      ]

      - to say, speak
      - to pick up

        - [(first person singular) present indicative active,  λέγω     , λέγω           ]
        - [(first person singular) future indicative active,   λέξω     , ἐρῶ            ]
        - [(first person singular) aorist indicative active,   ἔλεξα    , εἶπον/εἶπα     ]
        - [(first person singular) perfect indicative active,  (missing), εἴρηκα         ]
        - [(first person singular) perfect indicative passive, λέλεγμαι , λέλεγμαι       ]
        - [(first person singular) aorist indicative passive,  ἐλέχθην  , ἐρρέθην/ἐρρήθην]

中国人学习韩语有先天优势，加之韩语本身也是一门相当简单的语言，所以这里将语法和词汇合并在一起；每一项也只由 term（韩）和 definition（中）组成，

vocabulary:
  - term: string
    definition: list of strings
    example:
      - Korean: 제가 아무렴 그쪽 편에 서겠어요
        Chinese: 我无论如何都会站在你这边
      - Korean: ...
