The Semantic Web standardization and their growing usage in professional communities, both governmental and non-governmental, have naturally driven for accelerating the growth of published data volume in the virtual space by 422 published datasets in 2011 to 9,960 until 2019, totaling of 192,230,648 triples from various areas as medicine, education, art, history, technology, public administration etc. This trend of increasing of the semantic datasets published in the virtual space, leads to the emergence of a new challenge: ensuring the data quality; a first step in this direction being made by Tim Berners-Lee in 2010, when he defined a set of criteria that data scientists are encouraged to use it for ensuring a highest quality level of datasets. However, an important shape has not been mentioned: data accuracy, a feature not strictly specific to semantic data but which is applied to any type of data representation. The paper starts with a brief presentation of the most important metrics used to determine the level of data quality, along with a brief introduction of the most used string similarity algorithms. After that, the paper presents a new feature for an existing open data integration tool, called Karma, that allows users, such as data analysts and scientists, to improve their time management plan by reducing the time needed to clean their data. This feature has been implemented as a string suggestion for miswritten strings by using the presented string similarity metrics, keeping, at the same time, the framework design and the framework workflow too.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
