In this article, we will examine the problem of Information extraction (IE), an advanced branch of research that focuses on extracting semantic information from texts. From here, we will have many applications for many domains such as Web mining (extracting famous names, hot products, comparing product prices, researching competitors, analyzing customer psychology), Biomedical , Business intelligent, Financial professional (market assessment from different sources: rising and falling petrol prices, war information, politics between countries, new laws in the business market), Terrism event (use of weapons) what gas, who is the target of the attack).

Viewing: What is natural language processing

After lexical and syntactic preprocessing steps such as sentence separation, word separation, parsing, and word classification. From IE we will simplify into subproblems including: Named entity recognition (NER: people, organization, location), Coreference resolution and Relation between two entities. possible (Relation extraction – RE: founderOf, headQuartedIn). The experimental models will be evaluated through the Precision, Recall, F1-score indexes. Here is an example of extracting relationships in a sentence.

Part-of-speech tagging (POS) is probably the earliest problem studied and known to everyone when starting to specialize in natural language processing. In this article, we will learn about the problem of labeling from the type, the basic approaches and algorithms to solve this problem.

The exploitation of these data is the key point for businesses to quickly implement their decisions compared to the competition.

What is the problem here? There is too much information to process at once (more than 85% of the world’s data is unstructured), and the data size is increasing. For many businesses, it is impossible to have staff read everything that is supposed to be important (what customers are saying about the product, what our competitors are doing). .
