INTRODUCTION

"I just don't know where to startlooking for information.

I can't work out my reading list - and don't know how to use

the library catalogue. AND I've heard people talk about

electronic databases! What are they?

Help!"

What is a database?

• A database is a computer readable file in which the text or other sets of data have a defined structure supperted by a set of programs called the

Database Management System (DBMS)


BIBLIOGRAPHIC DATABESES

• Bibliographic databases have developed from abstract journals, abstracting and indexing services employing computer technology. They contain:

Bibliographic data

Abstracts

Keywords and/or other classification codes added to the records


The basic structure of database

• Records

• Data fields


What is a record?

• A record contains all the data belonging to one unit of the database. In the case of bibliographical databases, to a single publication (article) or document.


What is a data field?

• Data fields are separate parts of a record, marked with specific names (labels). Each fields refers to a single data element.

• It consists of two parts: - name (label) - content

Data fields are independently searchable elements in the data base.


Types of the fields

• TI TITLE: Porcine reproductive and respiratory syndrome (PRRS)

AB ABSTRACT

• Much has been learned about this syndrome of multiple aetiology since it was identified in North America in the 1980’s, with subsequent spread throughout the world (by trade in pigs and boar semen). It was also known as ‘mystery swine disease’, ‘new pig disease’ and ‘blue-eared pig disease’. Current knowledge is summarized…

INDEX FILES

Index files or inverted files

There are generated by the search software

An alphabetical list of words or terms occuring in a specific data field of each record is called an index/inverted file for the given data field


Author and keyword indexes

• An index of all author names or that of all keywords (descriptions) can be generated, together with the number of their occurances in the database, and the number of records in which they occur. For each entry in such an index, the record identifiers are also indicated in the index file.


Common index file

• In some databases a common index file of all occuring words is generated and updated.

• (except for stop words, which are frequently used words which are irrelevant from the point of view of searching: „and”, „for”, „ „good”, etc.)


SPIRS(SilverPlatter Information Retrieval System)

• Spirs has one main index that can be displayed, plus separate indexes for:

- Author (AU)

- Publication year (PY)

- Language (LA)

You can search the main index, you can also limit for any fields


Indexing for precise retrieval

• Indexing also means the adding of subject heading, descriptors, classification codes expressing the content of the document for which record is prepared. It is a significant process from the retrieval point of view, because


Retrieval point of view

• It relects the most essential concepts the publications deals with,

• It ensures the retrieval of documents dealing with the same or related subject, and

• It „translates” the diverse terminology of authors to a consistent and controlled language


Kids of information retrieval languages

• Subject categories or classification codesUsually broader categories, organised

hierarchially, reflecting the logic of a discipline

• Subject heading lists, thesaurus (keywords, descriptors), alphabetic ordered of natural language terms

• Special coding systems
