Post 1:
What is text analytics? How does it differ from text mining?
Text Analytics is applying of statistical and machine learning
techniques to be able to predict /prescribe or infer any
information from the text-mined data. Text mining is a tool that
helps in getting the data cleaned up.Text analytics and text
mining approaches have essentially equivalent performance.
Text analytics requires an expert linguist to produce complex
rule sets, whereas text mining requires the analyst to hand-label
cases with outcomes or classes to create training data.
Differences between Text Mining and Text Analytics:
• Text Mining and Text Analytics solve the same problems, but
use different techniques and are complementary ways to
automatically extract meaning from text.
• Text Analytics is developed within the field of computational
linguistics. It has the ability to encode human understanding
into a series of linguistic rules which are generated by humans
are high in precision, but they do not automatically adapt and
are usually fragile when tried in new situations.
• Text mining is a newer discipline arising out of the fields of
statistics, data mining, and machine learning. Its strength is the
ability to inductively create models from collections of
historical data. Because statistical models are learned from
training data they are adaptive and can identify “unknown
unknowns”, leading to the better recall. Still, they can be prone
to missing something that would seem obvious to a human.
• Text analytics and text mining approaches have essentially
equivalent performance. Text analytics requires an expert
linguist to produce complex rule sets, whereas text mining
requires the analyst to hand-label cases with outcomes or
classes to create training data.
• Due to their different perspectives and strengths, combining
text analytics with text mining often leads to better performance
than either approach alone.

2. What technologies were used in building Watson (both
hardware and software)?
Watson is an extraordinary computer system (a novel
combination of advanced hardware an software) designed at
answering questions posed in natural human language.Watson is
an artificially intelligent computer system capable of answering
questions posed in natural language, developed in IBM's
DeepQA project by a research team led by principal investigator
David Ferrucci. Watson was named after IBM's first CEO and
industrialist Thomas J. Watson. The computer system was
specifically developed to answer questions on the quiz show
Jeopardy! In 2011, Watson competed on Jeopardy! against
former winners Brad Rutter and Ken Jennings.
Watson received the first prize of $1 million.The goal was to
advance computer science by exploring new ways for computer
technology to affect science, business, and society.IBM
undertook a challenge to build a computer system that could
compete at the human champion level in real time on the
American TV quiz show Jeopardy!The extent of the challenge
included fielding a real-time automatic contestant on the show,
capable of listening, understanding, and responding- not merely
a laboratory exercise.watson called DeepQA, is a massively
parallel, text mining focused, probabilistic evidence based
computational architecture.Many techniques were combined
such that overlapping approaches can bring their strengths to
bear and contribute to improvements in accuracy, confidence,
and speed.overarching principles in Deep QA are:
a) massive parallelism- consider multiple interpretations and
hypothesis
b)many experts- integration, application, and contextual
evaluation of loosely coupled questions and analytics
c)pervasive confidence estimation- no one component commits
to an answer but all are weighed against confidence intervals
d) integrate shallow and deep knowledge
Software:

Watson uses IBM's DeepQA software and the Apache UIMA
(Unstructured Information Management Architecture)
framework. The system was written in various languages,
including Java, C++, and Prolog, and runs on the SUSE Linux
Enterprise Server 11 operating system using Apache Hadoop
framework to provide distributed computing.
Hardware:
The system is workload optimized, integrating massively
parallel POWER7 processors and being built on IBM's DeepQA
technology, which it uses to generate hypotheses, gather
massive evidence, and analyze data.Watson is composed of a
cluster of ninety IBM Power 750 servers, each of which uses a
3.5 GHz POWER7 eight core processor, with four threads per
core. In total, the system has 2,880 POWER7 processor cores
and has 16 terabytes of RAM.According to John Rennie, Watson
can process 500 gigabytes, the equivalent of a million books,
per second. IBM's master inventor and senior consultant Tony
Pearson estimated Watson's hardware cost at about $3 million.
Its performance stands at 80 TeraFLOPs which is not enough to
place it at Top 500 Supercomputers list.According to Rennie,
the content was stored in Watson's RAM for the game because
data stored on hard drives are too slow to access.
Data:
The sources of information for Watson include encyclopedias,
dictionaries, thesauri, newswire articles, and literary works.
Watson also used databases, taxonomies, and ontologies.
Specifically,DBPedia, WordNet, and Yago were used.The IBM
team provided Watson with millions of documents, including
dictionaries, encyclopedias, and other reference material that it
could use to build its knowledge.Watson is a question answering
(QA) computer system developed by an IBM Research team and
named after IBM's first president as part of a project called
DeepQA. What makes it special is that it is able to compete at
the human champion level in real time on the TV quiz show,
Jeopardy! In fact, in 2011, it was able to defeat Ken Jennings,
who held the record for the longest winning streak in the game.

Like Deep Blue has done with chess, Watson is showing that
computer systems are getting quite good at demonstrating
human-like intelligence.1
3. Why is the popularity of text mining as an analytics tool
increasing?
Text mining is also considered as the process for knowledge
discovery in the textual databases and the process is not fully
automated for extracting the useful and important pattern from a
huge collection of unstructured data.Text mining is the process
of exploring and analyzing large amounts of unstructured text
data aided by software that can identify concepts, patterns,
topics, keywords and other attributes in the data. It's also known
as text analytics, although some people draw a distinction
between the two terms; in that view, text analytics is an
application enabled by the use of text mining techniques to sort
through data sets.2
Text analytics is a concept that includes information retrieval
(e.g., searching and identifying relevant documents for a given
set of key terms) as well as information extraction, data mining,
and Web mining. By contrast, text mining is primarily focused
on discovering new and useful knowledge from textual data
sources. The overarching goal for both text analytics and text
mining is to turn unstructured textual data into actionable
information through the application of natural language
processing (NLP) and analytics. However, text analytics is a
broader term because of its inclusion of information retrieval.
You can think of text analytics as a combination of information
retrieval plus text mining.
Popular application areas of text mining
· Information extraction. Identification of key phrases and
relationships within text by looking for predefined sequences in
text via pattern matching.
· Topic tracking. Based on a user profile and documents that a
user views, text mining can predict other documents of interest
to the user.
· Summarizing a document to save time on the part of the

reader.
· Identifying the main themes of a document and then placing
the document into a predefined set of categories based on those
themes.
· Grouping similar documents without having a predefined set
of categories.
· Concept linking. Connects related documents by identifying
their shared concepts and, by doing so, helps users find
information that they perhaps would not have found using
traditional search methods.
· Question answering. Finding the best answer to a given
question through knowledge-driven pattern matching.

Post 2:
Text analytics is an automated method for analyzing and
extracting valuable information from a piece of text. This is
also achieved with the aid of a program designed to go through
long texts and collect information that may be useful for the
purposes of marketing, branding and other research. To analyze
blogs, tweets, social media posts, reviews, comments and other
forms of content, many businesses use text analytics to find
meaning and gather information with the aid of algorithms and
machine learning software.
While the common goal for both text analytics and text mining
is to turn unstructured textual data into actionable information
by applying natural language processing (NLP) and analytics,
their meanings are very different, at least to some experts in the
sector. According to them, text analytics is a wider field that
involves retrieval of information (e.g. scanning and finding
relevant documents for a given set of key terms) as well as

extraction of information, data mining, and web mining, while
text mining focuses mainly on discovering new and useful
knowledge from textual data sources. Based on this definition
of text analytics and text mining, we can say that Text Analytics
is the combination of Information Retrieval and Text Mining
(which includes Information Extraction, Data Mining and Web
Mining).
Watson used advanced technologies like Text Mining, Text
Analytics and Natural Language Processing which includes the
following:
· Parsing
· Question Classification
· Question Decomposition
· Automatic Source Acquisition and Evaluation
· Entity and Relation Detection
· Logical Form Generation
· Knowledge Representation and Reasoning
In areas where very large quantities of textual data are
produced, such as law (court orders), academic science
(research articles), finance (quarterly reports), medicine
(discharge summaries), biology (molecular interactions),
technology (patent files), and marketing (customer comments),
the benefits of text mining are evident. Another field where
automated unstructured text processing has had a huge influence
is in electronic correspondence and e-mail. Text mining can not
only be used to identify and delete junk e-mail but can also be
used to automatically prioritize e-mail based on the level of
significance and to produce automated responses (Weng and
Liu, 2004). That's why the popularity of Text Mining is
increasing as an analytics tool.
