WorldCat Discovery release notes, Arabic language search and sort

 

Release Date: November 2023

Introduzione

The following release notes are for Arabic language searching and sorting support in WorldCat Discovery, completed NOVEMBER 2023

WorldCat Discovery now includes the following enhancements to searching and sorting for the Modern Standard Arabic language that a native speaker expects:

Cerca

  • We normalize terms so they are treated the same with and without diacritics, definite articles, prefixes and kashida.
  • We maintain lists of protected words (that are not normalized), stop words and word stems (for automatic, default matching on variant forms of a word).

Ordinamento

  • We remove leading articles and normalize hamza (especially with letter “ا “) before applying Unicode collation.

These Arabic language searching and sorting improvements complement WorldCat Discovery’s Arabic user interface, introduced in May 2021.

Modern Standard Arabic search and sort features 

Cerca

Your library’s users searching for words or phrases in Modern Standard Arabic now get search results that meet the expectations of native Arabic speakers. These include:

Diacritics

WorldCat Discovery returns the same results regardless of whether users enter search terms with or without diacritics such as hamza “ء” or madda “آ”.  For example, we treat the following as equivalent:

  • “ى” and ”ي”,  
  • “ه” and ” ة ”
  • “آ” “ا” “إ” “أ”

Definite articles and prefixes

For title searches, results are the same with or without preceding definite articles or prefixes. For example:

  • Definite articles are dropped: “ال“
  • Prefixes are ignored: “ب” “ك” “ف” “لل”

Kashida

WorldCat Discovery treats characters the same whether elongated or not. For example:

  • With kashida: “مـديـنــــــــــــــــة “
  • Without kashida: “مدينة”

The following table provides further examples:

Protected words

OCLC maintains a list of Modern Standard Arabic words that are protected from the above normalization processes and are preserved unchanged. Normalization, such as removing definite articles or prefixes, would either change the meaning of these words or render them meaningless. 

Esempio:

  •  المانيا      (Germany)                   Without the leading article, the word مانيا has no meaning.

Stop words

OCLC maintains a list of Modern Standard Arabic stop words that WorldCat Discovery ignores for search matching because they occur so commonly across records that they do not help users select or distinguish between records.

Stemming

OCLC maintains a list of Modern Standard Arabic word stems that assist with automatic, default matching on variant forms of a word. 

Ordinamento

Alphabetic sorting of Modern Standard Arabic search results now meets native Arabic speakers’ expectations.

Alphabetic sorting is used on WorldCat Discovery search results for:

Ordinamento

  • Autore (A-Z)
  • Titolo (A-Z)

Sfaccettatura

  • Autore/Creatore

Alphanumeric sorting of call numbers is used on the item details page for:

  • Browse the Shelf

Before applying sorting to Modern Standard Arabic, we remove leading articles and normalize hamza, especially with letter “ا “. We then sort Modern Standard Arabic author, title, and call number fields using the default collation order of the Unicode Collation Algorithm that we apply for all scripts and languages.

Title (A-Z) sorting example

Searching for the term المقالات (the articles) in the title ti: index

Record no.
