O Quality data should have some criteria: accuracy integrity completeness validity consistency uniformity density

Data Standardization



Data standardization:O consistency,

between the content and format of data types represented in a system,

for data mapping and data outputs.

Oprocesses to improve information retrieval,Oloss of data,Ounduplicated data.


Essential processes for;Ouser interactionOmeeting information needsAdvantages;Oincreases the clarity level of data,Oprovides internal consistency of data,Opresents a high quality and consistent platform for users,



Data CleaningDetecting and removing errors and inconsistencies from data (Rahm and Do, 2000).

Data cleaning is to weed out unsuitable or incorrectly entered data in the data set (Tekerek, 2011).

Data cleaning is also stated as a process that increases data quality and solves data quality problems.


Data Standardization and Metadata

O Usage of digital collections effectively is dependent on the metadata quality.

O management of digital resources usefully at a wider level requires some degree of standardization of data and metadata (Gartner, 2008, p. 4).


O Standardized data utilize: efficient discovery, access, transfer and use of common terms, common definitions, etc. (Gartner, 2008, p. 5;

Why, 2013).



Standardized metadataOenables users effective and efficient access to data by using a set of terminology (GeoNetwork, 2008, p. 32).

Oallows users’ access to the information they need (Xie and Shibasaki, 2013).



LIS ETD Archive in Turkeyhttp://bbytezarsivi.hacettepe.edu.tr


LIS ETD Archive in Turkey

Objectives of the project are:OCreating a union catalogODeveloping a digital archive that presents full texts and bibliographic descriptions OIdentification of ETDs via interoperable and standardized structures.OIncreasing access and visibility OProviding OAI-PMH standards and protocols, and an interoperable environment for search engines.


O 436 post-graduate (masters and doctorate)

O by the end of 2012.

Content & data structure


O First stage;O Data set was determined and created

via various supplementary resources,O Second stage;

O Rules and norms that will be used for the standardization processes were determined,

O Final stage;O Data integrity were provided, and false

and flawed data were corrected.
