Data Labeling is a process of attaching meaningful fields to various types of digital data such as audio files, text, images, videos and more.

It is a time-consuming process, as it involves human interaction for the most accurate results.
Let’s talk about some common tasks about Data Labeling:

POS tagging

The function of POS tagging is to identify the grammatical functions of words in a sentence. This is the basic step before in-depth analysis of grammar or other complex language processing issues.

Typically, a word can have many grammatical functions, for example:

In the sentence “con ngựa đá đá con ngựa đá “, the same word “đá” but the first and third words have grammatical functions as nouns, but the second word is a verb in the sentence.

POS tagging is considered the basis for higher semantic problems.

Named-Entity recognition

Named-Entity recognition of medium semantic value is often used to classify text.

For example: Ms. Ba [PERSON] sells bread [FOOD] in 13 ward [ADDRESS].

Machine translation

The method of machine translation simply means that the input is a sentence of A language, the output is the sentence of corresponding B language.

This problem was very urgent during World War II, when enemy information needed to be translated in the shortest possible time, so that the leaders could make urgent strategies.

Speech recognition

As the name of this Labeling task, the input will be the voice sound, the output will be a text sentence.

Today, according to Apple statistics, users prefer to use their voice to enter text rather than traditional keyboard input, at the same time, human-machine interaction in this way has faster input speed.

Although there are still certain difficulties, with increasingly advanced technology, this labeling task is gradually being improved and developed.
