UNAIR NEWS –听Recently, the term听鈥渂ig听data鈥 has been discussed more on social media.听However, there are still many people who do not understand what听big听data is.
Ratih Ardiati Ningrum, M.S., M.Stat., one of the lecturers of Data Science Technology Program, Faculty of Advanced Technology and Multidiscipline (FTMM), 听(UNAIR) revealed that data can be categorized as听听鈥渂ig听data鈥 based on five things.听First, said Ratih, on听volume听(size).听She explained that if there is data with a large size, that data is included as听big听data.听
Second, added Ratih, on听velocity听(speed).听If a data has a fast flow or movement, that data is also included as听big听data.听Furthermore, the third is based on听a wide听variety听(types), where in fact a data does not only consist of structured data but also semi-structured and听unstructured听data.
“Structured data is data that has been neatly arranged, while听unstructured听data听is data in the form of images or sounds such as data on听X-Ray听images听and other kinds of data,” she said on Tuesday, March 16, 2021.
Then, continued Ratih, the fourth is based on听veracity听(accuracy or consistency).听She explained that the听veracity听aspect emphasizes whether the data is valid data or not.听Finally, data can be categorized as听big data based on听value.
“Value is related to the value of data, meaning that the data can provide听insight, knowledge,听听and information,” explained Ratih.
Big听data, said Ratih, can be used in various sectors of human life after going through the听data听mining听or data processing.听Some examples of the use of big data include agriculture, education, health and other fields.
“If we can process data, for example regarding听product听reviews听in an听e-commerce, the data can be information for sellers because from听product听review听data, we can model which product is acceptable to the public, what the product deficiencies are, and so on,” she added.
Ratih said the term听big听data has existed since ancient times.听However, according to her, the term is starting to become a discussion because it is motivated by the current conditions in which humans live in the era of the industrial revolution 4.0 and听society听5.0 which is all digital.
“The current technology is getting more advanced, at least everyone has one听smartphone听and you can imagine how much data each person produces,” she said.
As a closing statement, Ratih emphasized that data has many benefits and through such data there will be a lot of information that can be obtained if the data processing is done properly. (*)
