What is Opencalais?

Launched in 2008, Open Calais is a free web service provided by Thomson Reuters. It enables users to create and attach rich semantic metadata from their submitted unstructured text and provide an output in RDF format that can be used for the semantic web.

What is tagging in text analytics?

Text tagging is the process of manually or automatically adding tags or annotation to various components of unstructured data as one step in the process of preparing such data for analysis. Tagging takes place at a more granular level than categorization, and may offer additional benefits in terms of insight.

What is intelligent Tagging?

What is Intelligent Tagging? Intelligent Tagging uses Natural Language Processing (NLP), text analytics and data-mining technologies to derive meaning from vast amounts of unstructured content, including research reports, news articles and more. It processes millions of text documents daily for financial professionals.

What is Textmining approach?

Text mining, also known as text data mining, is the process of transforming unstructured text into a structured format to identify meaningful patterns and new insights. Structured data can include inputs such as names, addresses, and phone numbers. Unstructured data: This data does not have a predefined data format.

What is tagged text?

A text file that contains identification fields (tags) embedded within the sentences and paragraphs. For example, HTML tags describe how the text is formatted for display and printing, whereas XML tags define the meaning of the data.

What is Textmining PDF?

Text mining has a definition of mining data in the form of text where data sources are usually obtained from documents, and the purpose is to search for words that can represent the contents of the document so that analysis of the relationship between documents can be done (Kumar and Bhatia, 2013) .

Why POS tagging is important?

Part of Speech (hereby referred to as POS) Tags are useful for building parse trees, which are used in building NERs (most named entities are Nouns) and extracting relations between words. POS Tagging is also essential for building lemmatizers which are used to reduce a word to its root form.

What is POS NLP?

Whats is Part-of-speech (POS) tagging? It is a process of converting a sentence to forms – list of words, list of tuples (where each tuple is having a form (word, tag)). The tag in case of is a part-of-speech tag, and signifies whether the word is a noun, adjective, verb, and so on.

When did Textmining start?

In the late 1990s, researchers started to use text as data, which gave rise to text mining. Early text mining basically applied data mining and machine learning algorithms on text data without using NLP techniques such as parsing, part-of-speech tagging, summarization, etc.

What is NLP or text analysis?

NLP. Natural language processing (or NLP) is a component of text mining that performs a special kind of linguistic analysis that essentially helps a machine “read” text.
