Entity Analysis

Entity Analysis is a core function of the Google Cloud Natural Language API that identifies and classifies entities within the text data. An ‘entity’ here refers to any named thing or object that is of particular significance, such as people, organizations, locations, events, products, or even specific numerical quantities and dates.

Here’s a more detailed look at how entity analysis works:

Identification

The first step in entity analysis is the identification of entities. The API scans the provided text and pinpoints words or phrases that represent entities. It uses Google’s extensive knowledge graph and machine learning models to recognize millions of entities, even when they’re referred to indirectly.

Classification

Once the entities are identified, the API classifies them into predefined types, such as PERSON, LOCATION, ORGANIZATION, EVENT, WORK_OF_ART, CONSUMER_GOOD, and many more. This classification provides valuable context about what the entity represents.

Salience Score

For each recognized entity, the API assigns a salience score. This score, ranging from 0.0 to 1.0, reflects the entity’s importance or centrality in the entire text. A higher salience score means the entity is more important to the overall context of the text.

Metadata

When available, the API also provides additional metadata about recognized entities. This can include a mid (Machine ID) that correlates the entity to more information in Google’s Knowledge Graph, and a Wikipedia URL if the entity is well-known and has a dedicated Wikipedia page.

Mentions

Finally, the API also captures the mentions of each entity in the text. Each mention contains the text as it appeared in the document, its type (PROPER or COMMON), and the sentiment associated with that mention.

By providing these detailed insights, entity analysis can help applications understand the subject and context of the text. It’s valuable in various scenarios, such as news aggregation, content recommendation, and customer feedback analysis, to name a few.

Sentiment Analysis

Sentiment Analysis, another core function of the Google Cloud Natural Language API, evaluates the overall sentiment or emotional tone conveyed within a piece of text. This analysis can be incredibly useful in determining how people feel about a particular subject, be it a product, service, event, or any other entity.

Sentiment Analysis is achieved through the following features:

Sentiment Score

The API assigns a sentiment score to each piece of text analyzed. This score, a floating-point value ranging between -1.0 and 1.0, represents the emotional leaning of the text. A score of -1.0 suggests a strong negative sentiment, 0 represents a neutral sentiment, and a score of 1.0 indicates a strong positive sentiment.

Sentiment Magnitude

Alongside the sentiment score, the API also assigns a sentiment magnitude, a non-negative number that represents the strength or intensity of the sentiment irrespective of its positive or negative direction. Unlike the sentiment score, the magnitude is not normalized and ranges from 0 to infinity, reflecting the total sentiment expressed in the text.

Entity-Level Sentiment

In addition to the overall sentiment of the text, the API can also analyze sentiment at the entity level. This means it can determine the sentiment associated with each recognized entity in the text, providing a more granular view of the sentiment expressed.

Mention-Level Sentiment

The sentiment analysis can be further refined to the mention level. For each entity identified, the API can also evaluate the sentiment of each of its mentions in the text.

Part-of-Speech Tagging

Once the text is tokenized, the API assigns a part-of-speech tag to each token. This tag indicates the grammatical role that the token plays in the text, such as a noun, verb, adjective, preposition, etc. This tagging helps in understanding the grammatical context of each word within the sentence.

Morphological Analysis

The API also performs morphological analysis on each token. This process identifies the base form, or lemma, of each word, along with its inflectional and derivational features. For example, it can determine that the word ‘went’ is the past tense form of the verb ‘go’.

Dependency Parsing

To understand the relationship between the words in a sentence, the API constructs a parse tree that reflects the grammatical structure of the sentence. Each token is linked to another through a grammatical relationship, or dependency, revealing the hierarchical arrangement of the words and phrases within the sentence.

Sentence Boundary Detection

Finally, the API identifies the boundaries of sentences within the text. This feature is especially useful when dealing with large blocks of text, as it allows the API to analyze each sentence individually, ensuring more accurate and meaningful results.

Syntax Analysis can greatly aid applications that require a deep understanding of text, including information extraction, machine translation, question-answering systems, and more.
