4Terminological entry structure
In a terminology database, each term and its related set of data elements constitute a terminology unit according to different usage purposes. Each data element occupies a field (or subfield), and a class of data elements with the same attributes constitutes a data field. 4.1Number of fields
The number of fields should be determined according to the needs of the terminology database application, in accordance with the requirements of standardization, to meet user needs to the greatest extent, and to avoid waste.
4.2'Field names
should use characters that are easy to remember and identify. Example 1:
Field name: Serial number (xuhao/number) Abbreviation: xh (Chinese Pinyin) or Num (English) Example 2:
Field name: Definition (dingyi/definition) Abbreviation: dy (Chinese Pinyin) or def (English abbreviation) 4.3 Field identifiers
Field identifiers can use letters or numbers. If numbers are used, they should comply with the requirements of Appendix A of GB/T13726-1992. Field identifiers and their compilation principles and methods should be indicated in the documents provided to users. 4.4 Field data types
4.4.1 Character type
It can be Chinese characters, letters, numbers, special symbols, etc. Terminology, definitions, etc. should use character type fields. 4.4.2 Numeric type
It can be integers, decimals, positive and negative numbers, etc. Serial numbers should use numeric fields. 4.4.3 Date type
The structure of date type data field is: CCYYMMDD. Example: 20010515 means May 15, 2001. GB/T15387.2—2001
The date of generation of terminology source (such as standard release date, dictionary publication date, etc.) and the date of generation of terminology record should use date type field.
4.4.4 Others
Terminology data may also involve other field data types, such as logical data types. 4.5 Field length
Terminology database should use variable length fields as much as possible. When using fixed length fields, factors such as convenience of use and saving storage space should be considered. 4.6 Relationship between fields
According to the characteristics of the relationship between terminology data elements, the relationship between fields can be one-to-one (1:1), one-to-many (1:N) or many-to-many (MN).
4.7 Mandatory level of fields
The mandatory level of fields should be determined according to the purpose of the termbase. 4.7.1 Mandatory fields
When the terminology data category is the minimum information required to form a terminology entry, use this type of field. For example, "term" and "definition" in a concept-oriented termbase, "term" and "foreign equivalent" in a translation-oriented termbase, etc. Mandatory fields must be set up and cannot be left blank. 4.7.2 Optional fields
When the terminology data category is the necessary information to form a terminology entry, use this type of field, but it can be left blank. For example, synonyms and abbreviations of terms in a translation-oriented termbase. 4.7.3 Optional fields
When the terminology data category is optional information to form a terminology entry, use this type of field. For example, grammatical information, context, etc. 4.8 Field repeatability
When terminology data elements (such as synonyms) belonging to the same terminology data category need to appear several times in one record, the same field can be reused.
4.9 Field combination
Almost all data elements (fields) of terminology data categories can be combined with data elements (fields) of one or more terminology data categories to form a new terminology entry.
4.10. Subfield
When a certain field may have several values, or a field needs to reflect several contents, subfields can be used. a) A term may have several synonyms, which can be further divided into subfields according to the usage status, such as priority, permission, and rejection. b) The synonymy (degree) field needs to be divided into subfields, such as constant equal to (three), greater than (>), less than or equal to (<=), intersection (X), synonym (~), antonym (→), etc.
4.11 Cross-references
There are cross-references between different records (such as one term referring to another term), between different files (such as the main file and the inverted file); and between different databases (such as the graphic database and the text database, and between databases in different languages). 3
GB/T15387.2—2001
5 Functions of the terminology library
5.1 User interface
It should be able to provide a good Chinese character processing environment and a friendly user interface. The designed screen should have the following functions:
a) Human-computer dialogue.
The user inputs questions or other relevant information to the machine through the keyboard or other input devices, and the machine provides answers, prompts or other relevant information to the user through the display screen or other output devices. b) Menu drive.
Different menus for system management and user query should be set according to needs. A menu system should be designed to display multiple choices for users, and multi-level menus can be designed according to needs.
For example:
First-level menu: main function selection. For example, data input, data maintenance and update, data retrieval, sorting and printing, etc.; Second-level menu: sub-function selection, sub-items in a single function, conditions, etc. For example, browsing, setting search terms, displaying search results, etc. in the data retrieval function;
Third-level menu: selection of the next level of detailed functions that need to be designed. c) Prompt function.
For example:
Error prompt: indicating the nature and type of the error, as well as how to correct it; Rejection prompt: indicating and warning of invalid or wrong operations; operation step prompt.
d) Help function.
For example:
Specific and detailed instructions for correct operations; information on relevant content, including common codes such as language code, subject code, source institution code, responsible person code and their meanings: explanation of the relevant screen display content, the meaning and range of parameter values, and command or function selection descriptions. The help function can be realized by using window technology or calling auxiliary libraries and auxiliary screens. This state should be easy to enter and exit and return to the original operation state.
e) Other functions required by users.
For example; browsing, window, etc.
5.2 Data retrieval
In addition to being able to retrieve a single term and corresponding information (definition, foreign language equivalent, etc.), the term library should also be designed with the following types of retrieval according to needs.
a) Internal attribute retrieval.
Retrieve according to classification language and thesaurus language. Classification language retrieval results in all systematic terms in a certain field that are suitable for a certain classification; thesaurus language retrieval results in all terms that a certain term may involve, including related terms in other fields. b) External attribute retrieval.
For example:
Retrieve all terms contained in the document according to the cataloging data of the term source bibliography; retrieve all terms compiled (formulated) by the source institution (or responsible person); retrieve the annual changes in term compilation according to the year. c) Combined attribute retrieval.
Combination retrieval of the same or different attributes. 4
