12. 12. 06 Lexical Databases: Toolbox



Presentation on „Toolbox“ by Sascha Griffith

  • a computational tool developed by the SIL International (formerly known as the Summer Institute of Linguistics)

  • desined for field work purpose

  • a database application that interlinearizes, analyses and stores text and can convert this into an alphabetically ordered dictionary

  • was called „Shoebox“

  • eases work of linguist

    SIL lists Toolbox



    Toolbox' main functions are

    • viewing and searching ( click on arrows on the top left of the page, click on „database“ and „search“ to search)

    • browsing ( Alt + R)

    • editing ( „Edit“ , „Field&ldquo

    • sorting ( „Database“ , „Sorting“, sorting by field)



    To get the software



    Entering text

    • select text in source document

    • Press ctrl-c

    • Go to text row (tx) and paste (ctrl-v) the text into the right column

    • Enter the title of the text into text identification

    • Enter an abbreviation of the title into reference line (the references can later be automatically numbered)

    • copy and paste selected text passages into Toolbox

    • When the text is added one should press enter so that ft (free translation) reappears

    • After entering the text press Alt-I (mb, ge & ps will reappear.

    • Sometimes Toolbox does not recognize morphemes, then you have to add them by leaving a space between them and add them to the dictionary



    Making an entry

    • Mark a word in the line mb

    • Click on this word using the right mouse button

    • Click 'Insert'

    • Enter the lexical properties into the dictionary field at the bottom of the screen



    Wordlist, Concordance and dictionary

    • The dictionary is entered manually as shown

    • A wordlist can be produced using the menu 'tools' and in this menu 'wordlist' (or by pressing alt-l)

    • A concordance can be produced can be produced by using the menu 'tools' and in this menu 'concordance' (or by pressing ctrl-l)

    • A new text window can be added into a new text file by choosing the menu 'database' and where one will find 'new record'



    Additional Information

    • you can export Toolbox data into a word processor file

    • To add a new data category (e.g. the pronunciation) click on the left column in the text window and press ctrl-e.

       

    Note on dictionary making

    • What is seen in the left column of the text window is called data categories (or datcats), which are called fields in Toolbox, what can be seen on the right side is (language) data or records as Toolbox refers to them. The fields represent the microstructure of a dictionary.



    How are words built?

       

    • Inflection: marks the syntagmatic relation of words to their contexts

    • syntactic context: agreement in person, number, case

    • situational context: temporal relations, quantity

    • form: stem + affix


    • root/ morpheme creation: creates new POS ( parts of speech) and meaning

    • parts of 2 or more existing stems ( „galumph&ldquo

    • -> Jabbawocky


    • Derivation: creates new part of speech

    • stem + affix


    • Compounding: creates meanings and sometimes new POS

    • at least 2 existing stems



    Internal structure of words

    English words consist of a STEM and an INFLECTION

    • STEM has a lexical meaning

    • INFLECTION has a grammatical meaning



    Stems of English words are ...

    • simple ( roots, lexical morphemes) -> boy, table, chair, red

    • complex, at least one of the following

    • Derivations ( a stem and a derivational affix) -> re- write

    • Compounds ( a stem plus another stem) -> table- cloth

    • Both ( synthetic compound) ( derivation plus a stem) -> bus driver

    Words are signs

    • inflected word -> phrase semantics, stress

    • compound word -> lexical semantics, stress ( „Hyde 'Park&ldquo

    • derived word -> lexical semantics, stress

    • morpheme -> lexical semantics, phonemes, stress

       

    A WORD is

    • a stem plus an inflection

       

    A STEM is either

    • a root (lexical morpheme) or

    • a derived stem ( stem plus affix) (derivation) or

    • a compound stem (stem plus stem) ( compounding)

    and nothing else is a stem ( recursive definition)



    A DERIVED STEM is either

    • a root ( zero derivation)

    • or a derived stem with an affix

    and nothing else is a derived stem



    A COMPOUND STEM is

    • a derived stem or a word + a derived stem or a word

    • a compound + a compound stem

    and nothing else is a compound stem
