What is NLP Sentiment Analysis? and Where is it used

By using the above code, we can simply show the word cloud of the most common words in the Reviews column in the dataset. Now it’s time to see how many negative words are there in “Reviews” from the dataset by using the above code. Now it’s time to see how many positive words are there in “Reviews” from the dataset by using the above code. In the above statement, we can clearly see that the “it” keyword does not make any sense.

This is repeated until a specific rule is found which describes the structure of the sentence. Here, the parser starts with the S symbol and attempts to rewrite it into a sequence of terminal symbols that matches the classes of the words in the input sentence until it consists entirely of terminal symbols. In the second part, the individual words will be combined to provide meaning in sentences. The following examples are taken from the Wikipedia page on lexical semantics. NLP-enabled sentiment analysis can produce various benefits in the compliance-tracking region.

Approaches to Meaning Representations

In the ever-expanding era of textual information, it is important for organizations to draw insights from such data to fuel businesses. Semantic Analysis helps machines interpret the meaning of texts and extract useful information, thus providing invaluable data while reducing manual efforts. The process of Natural Language Processing is divided into 5 major stages or phases, starting from basic word-level processing up to finding complex meanings of sentences. The words are commonly accepted as being the smallest units of syntax. The syntax refers to the principles and rules that govern the sentence structure of any individual languages. In the beginning of the year 1990s, NLP started growing faster and achieved good process accuracy, especially in English Grammar.

NLP helps machines to interact with humans in their language and perform related tasks like reading text, understand speech and interpret it in well format. Nowadays machines can analyze more data rather than humans efficiently. All of us know that every day plenty amount of data is generated from various fields such as the medical and pharma industry, social media like Facebook, Instagram, etc. And this data is not well structured (i.e. unstructured) so it becomes a tedious job, that’s why we need NLP. As we discussed the steps or different levels of NLP, the third level of NLP is Syntactic analysis or parsing or syntax analysis.

Technology & ISV

This approach doesn’t need the expertise in data analysis that financial firms will need before commencing projects related to sentiment analysis. An example of a successful implementation of NLP sentiment analytics (analysis) is the IBM Watson Tone Analyzer. It understands emotions and communication style, and can even detect fear, sadness, and anger, in text. To put it in another way – text analytics is about “on the face of it”, while sentiment analysis goes beyond, and gets into the emotional terrain. What keeps happening in enterprises is the constant inflow of vast amounts of unstructured data generated from various channels – from talking to customers or leads to social media reactions, and so on.
