-Analysis of words into root and affix(es) are called Morphological analysis of the word.  It is mandatory to identify root of a word for any natural language processing task. A root word can have various forms. For example, the word 'play' in English has the following forms: 'play', 'plays', 'played' and 'playing'.

 <h1 class="text-h2-lightblue">Building Chunker</h1><div class="content" id="experiment-article-section-1-content">
 <div style="font-size:14px;"><b>Chunking</b> is an analysis of a sentence which identifies the constituents (noun groups, verbs, verb groups, etc.) which are correlated. These are non-overlapping regions of text. Usually, each chunk contains a head, with the possible addition of some function words and modifiers either before or after depending on languages. These are non-recursive in nature i.e. a chunk cannot contain another chunk of the same category.
-<br><br>
-Some of the groups possible are:<br>
-1. Noun Group<br>
+<br/><br/>
+Some of the groups possible are:<br/>
+1. Noun Group<br/>
 2. Verb Group
-<br>
+<br/>
 For example, the sentence 'He reckons the current account deficit will narrow to only 1.8 billion in September.' can be divided as follows:
-<br><br>
+<br/><br/>
 [NP He ] [VP reckons ] [NP the current account deficit ] [VP will narrow ] [PP to ] [NP only 1.8 billion ] [PP in ] [NP September ]
-<br><br>
+<br/><br/>
 Each chunk has an open boundary and close boundary that delimit the word groups as a minimal non-recursive unit.

 <b><u>Hidden Markov Model</u></b>
-<br><br>
+<br/><br/>
 In the mid 1980s, researchers in Europe began to use Hidden Markov models (HMMs) to disambiguate parts of speech. HMMs involve counting cases, and making a table of the probabilities of certain sequences. For example, once you've seen an article such as 'the', perhaps the next word is a noun 40% of the time, an adjective 40%, and a number 20%. Knowing this, a program can decide that "can" in "the can" is far more likely to be a noun than a verb or a modal. The same method can of course be used to benefit from knowledge about following words.
-<br><br>
+<br/><br/>
 More advanced ("higher order") HMMs learn the probabilities not only of pairs, but triples or even larger sequences. So, for example, if you've just seen an article and a verb, the next item may be very likely a preposition, article, or noun, but much less likely another verb.
-<br><br>
+<br/><br/>
 When several ambiguous words occur together, the possibilities multiply. However, it is easy to enumerate every combination and to assign a relative probability to each one, by multiplying together the probabilities of each choice in turn.
-<br><br>
+<br/><br/>
 It is worth remembering, as Eugene Charniak points out in Statistical techniques for natural language parsing, that merely assigning the most common tag to each known word and the tag "proper noun" to all unknowns, will approach 90% accuracy because many words are unambiguous.
-<br><br>
+<br/><br/>
 HMMs underlie the functioning of stochastic taggers and are used in various algorithms. Accuracies for one such algorithm (TnT) on various training data is shown here.
-<br><br>
+<br/><br/>
 <b><u>Conditional Random Field</u></b>
-<br><br>
+<br/><br/>
 Conditional random fields (CRFs) are a class of statistical modelling method often applied in machine learning, where they are used for structured prediction. Whereas an ordinary classifier predicts a label for a single sample without regard to "neighboring" samples, a CRF can take context into account. Since it can consider context, therefore CRF can be used in Natural Language Processing. Hence, Parts of Speech tagging is also possible. It predicts the POS using the lexicons as the context.
-<br><br>
+<br/><br/>
 In this experiment both algorithms are used for training and testing data. As the size of training corpus increases, it is observed that accuracy increases. Further, even features also play an important role for better output. In this experiment, we can see that Parts of Speech as a feature performs better than only lexicon as the feature. Therefore, it is important to select proper features for training a model to have better accuracy.

 <div style="font-size:14px;"><b>Chunking</b> is an analysis of a sentence which identifies the constituents (noun groups, verbs, verb groups, etc.) which are correlated. These are non-overlapping regions of text. Usually, each chunk contains a head, with the possible addition of some function words and modifiers either before or after depending on languages. These are non-recursive in nature i.e. a chunk cannot contain another chunk of the same category.

-<p>Morphemes are considered as smallest meaningful units of language. These morphemes can either be a root word(play) or affix(-ed). Combination of these morphemes is called morphological process. So, word "played" is made out of 2 morphemes "play" and "-ed". Thus finding all parts of a word(morphemes) and thus describing properties of a word is called "Morphological Analysis". For example, "played" has information verb "play" and "past tense", so given word is past tense form of verb "play".</p><br>

 Morphology is the study of the way words are built up from smaller meaning bearing units i.e., morphemes. A morpheme is the smallest meaningful linguistic unit. For eg:<br/><br/>  
 <ul><li><b>बच्चों(bachchoM)</b>  consists of two morphemes, <i>बच्चा(bachchaa)</i> has the information of the root word noun "बच्चा"(bachchaa) and <i>ओं(oM)</i> has the information of plural and oblique case.</li><li><b>played</b> has two morphemes <i>play</i> and <i>-ed</i> having information verb "play" and "past tense", so given word is past tense form of verb "play".</li></ul><br/>

 Words can be analysed morphologically if we know all variants of a given root word. We can use an 'Add-Delete' table for this analysis.

-If we consider each word occurring in its correct location as an independent event,the probability of the sentences is : P(w(1), w(2)..., w(n-1), w(n))<br><br>
-Using chain rule:<br>

-<b><u> Bigrams</u></b><br>
-We can avoid this very long calculation by approximating  that the probability of a given word depends only on the probability of its previous words. This assumption is called Markov assumption and such a model is called Markov model- bigrams. Bigrams can be generalized to the n-gram which looks at (n-1) words in the past. A bigram is a first-order Markov model. <br>

 One major problem with standard N-gram models is that they must be trained from some corpus, and because any particular training corpus is finite, some perfectly acceptable N-grams are bound to be missing from it. We can see that bigram matrix for any given training corpus is sparse. There are large number of cases with zero probabilty bigrams and that should really have some non-zero probability. This method tend to underestimate the probability of strings that happen not to have occurred nearby in their training corpus.
-<br><br>
+<br/><br/>
 There are some techniques that can be used for assigning a non-zero probabilty to these 'zero probability bigrams'. This task of reevaluating some of the zero-probability and low-probabilty N-grams, and assigning them non-zero values, is called smoothing.

 The standard N-gram models are trained from some corpus. The finiteness of the training corpus leads to the absence of some perfectly acceptable N-grams. This results in sparse bigram matrices. This method tend to underestimate the probability of strings that do not occur in their training corpus.

 One major problem with standard N-gram models is that they must be trained from some corpus, and because any particular training corpus is finite, some perfectly acceptable N-grams are bound to be missing from it. We can see that bigram matrix for any given training corpus is sparse. There are large number of cases with zero probabilty bigrams and that should really have some non-zero probability. This method tend to underestimate the probability of strings that happen not to have occurred nearby in their training corpus.
 <br/><br/>
 There are some techniques that can be used for assigning a non-zero probabilty to these 'zero probability bigrams'. This task of reevaluating some of the zero-probability and low-probabilty N-grams, and assigning them non-zero values, is called smoothing.

 The standard N-gram models are trained from some corpus. The finiteness of the training corpus leads to the absence of some perfectly acceptable N-grams. This results in sparse bigram matrices. This method tend to underestimate the probability of strings that do not occur in their training corpus.
 <br/> <br/>
 There are some techniques that can be used for assigning a non-zero probabilty to these 'zero probability bigrams'. This task of reevaluating some of the zero-probability and low-probabilty N-grams, and assigning them non-zero values, is called smoothing. Some of the techniques are: Add-One Smoothing, Witten-Bell Discounting, Good-Turing Discounting.<br/><br/>
 
-<h4>Add-One Smoothing </h4><br/>
+</p><h4>Add-One Smoothing </h4><br/>
 
 In Add-One smooting, we add one to all the bigram counts before normalizing them into probabilities. This is called add-one smoothing.<br/><br/>
 
-<h4>Application on unigrams </h4></br>
+<h4>Application on unigrams </h4><br/>
 The unsmoothed maximum likelihood estimate of the unigram probability can be computed by dividing the count of the word by the total number of word tokens N
 
-<pre>
-P(w<sub>x</sub>) = c(w<sub>x</sub>)/sum<sub>i</sub>{c(w<sub>i</sub>)}
+<pre>P(w<sub>x</sub>) = c(w<sub>x</sub>)/sum<sub>i</sub>{c(w<sub>i</sub>)}
       = c(w<sub>x</sub>)/N
 </pre>
 
 <br/>
 Let there be an adjusted count c<sup>*</sup>.<br/>
-c<sub>i</sub><sup>*</sup> = (c<sub<i</sub>+1)*N/(N+V)<br/>
+c<sub>i</sub><sup>*</sup> = (c<sub<i< sub="">+1)*N/(N+V)<br/>
 where where V is the total number of word types in the language.
 <br/>
 Now, probabilities can be calculated by normalizing counts by N.<br/>
-p<sub>i</sub><sup>*</sup> = (c<sub<i</sub>+1)/(N+V) <br/><br/>
+p<sub>i</sub><sup>*</sup> = (c<sub<i< sub="">+1)/(N+V) <br/><br/>
 
 <h4>Application on bigrams </h4><br/>
 Normal bigram probabilities are computed by normalizing each row of counts by the unigram count:<br/>
 P(w<sub>n</sub>|w<sub>n-1</sub>) = C(w<sub>n-1</sub>w<sub>n</sub>)/C(w<sub>n-1</sub>)<br/><br/>
 For add-one smoothed bigram counts we need to augment the unigram count by the number of total word types in the vocabulary V:<br/>
-p<sup>*</sup>(w<sub>n</sub>|w<sub>n-1</sub>) = ( C(w<sub>n-1</sub>w<sub>n</sub>)+1 )/( C(w<sub>n-1</sub>)+V )<br/><br/><hr>

-Assigning part of speech to words by hand is a common exercise one can find in an elementary grammar class. But here we wish to build an automated tool which can assign the appropriate part-of-speech tag to the words of a given sentence. One can think of creating hand crafted rules by observing patterns in the language, but this would limit the system's performance to the quality and number of patterns identified by the rule crafter. Thus, this approach is not practically adopted for building POS Tagger. Instead, a large corpus annotated with correct POS tags for each word is given to the computer and algorithms then learn the patterns automatically from the data and store them in form of a trained model. Later this model can be used to POS tag new sentences.<br><br>

 <h1 class="text-h2-lightblue">POS Tagging - Hidden Markov Model</h1><div class="content" id="experiment-article-section-2-content">
 A Hidden Markov Model (HMM) is a statistical Markov model in which the system being modeled is assumed to be a Markov process with unobserved (hidden) states.In a regular Markov model (Markov Model (Ref: http://en.wikipedia.org/wiki/Markov_model)), the state is directly visible to the observer, and therefore the state transition probabilities are the only parameters. In a hidden Markov model, the state is not directly visible, but output, dependent on the state, is visible.

+<br/>
 Hidden Markov Model has two important components-
-<br>
-<br>
+<br/>
+<br/>
 1)Transition Probabilities: The one-step transition probability is the probability of transitioning from one state to another in a single step.
-<br>
-<br>
+<br/>
+<br/>

-Assigning part of speech to words by hand is a common exercise one can find in an elementary grammar class. But here we wish to build an automated tool which can assign the appropriate part-of-speech tag to the words of a given sentence. One can think of creating hand crafted rules by observing patterns in the language, but this would limit the system's performance to the quality and number of patterns identified by the rule crafter. Thus, this approach is not practically adopted for building POS Tagger. Instead, a large corpus annotated with correct POS tags for each word is given to the computer and algorithms then learn the patterns automatically from the data and store them in form of a trained model. Later this model can be used to POS tag new sentences.<br><br>

 A Hidden Markov Model (HMM) is a statistical Markov model in which the system being modeled is assumed to be a Markov process with unobserved (hidden) states.In a regular Markov model (Markov Model (Ref: http://en.wikipedia.org/wiki/Markov_model)), the state is directly visible to the observer, and therefore the state transition probabilities are the only parameters. In a hidden Markov model, the state is not directly visible, but output, dependent on the state, is visible.

 Hidden Markov Model has two important components-
-<br>
-<br>
+<br/>
+<br/>
 1)Transition Probabilities: The one-step transition probability is the probability of transitioning from one state to another in a single step.
-<br>
-<br>
+<br/>
+<br/>
 2)Emission Probabilties: : The output probabilities for an observation from state. Emission probabilities B = { b<sub>i,k</sub> = b<sub>i</sub>(o<sub>k</sub>) = P(o<sub>k</sub> | q<sub>i</sub>) }, where o<sub>k</sub>is an Observation. Informally, B is the probability that the output is o<sub>k</sub> given that the current state is q<sub>i</sub>
-<br><br>
+<br/><br/>
 For POS tagging, it is assumed that POS are generated as random process, and each process randomly generates a word. Hence, transition matrix denotes the transition probability from one POS to another and emission matrix denotes the probability that a given word can have a particular POS. Word acts as the observations. Some of the basic assumptions are:<br/>
 <pre>1. First-order (bigram) Markov assumptions:
 	a. Limited Horizon: Tag depends only on previous tag
-		P(t<sub>i+1</sub> = t<sub>k</sub> | t<sub>1</sub>=t<sub>j1,…,ti</sub>=t<sub>ji</sub>) = P(t<sub>i+1</sub> = t<sub>k</sub> | t<sub>i</sub> = t<sub>j</sub>)
+		P(t<sub>i+1</sub> = t<sub>k</sub> | t<sub>1</sub>=t<sub>j1,…,ti</sub>=t<sub>ji</sub>) = P(t<sub>i+1</sub> = t<sub>k</sub> | t<sub>i</sub> = t<sub>j</sub>)
 	b. Time invariance: No change over time
-		P(t<sub>i+1</sub> = t<sub>k</sub> | t<sub>i</sub> = t<sub>j</sub>) = P(t<sub>2</sub> = t<sub>k</sub> | t<sub>1</sub> = t<sub>j</sub>) = P(t<sub>j</sub> -> t<sub>k</sub>)
+		P(t<sub>i+1</sub> = t<sub>k</sub> | t<sub>i</sub> = t<sub>j</sub>) = P(t<sub>2</sub> = t<sub>k</sub> | t<sub>1</sub> = t<sub>j</sub>) = P(t<sub>j</sub> -&gt; t<sub>k</sub>)
 2. Output probabilities:
-	Probability of getting word wk for tag t<sub>j</sub>: P(w<sub>k</sub> | t<sub>j</sub>) is independent of other tags or words!<br>
+	Probability of getting word wk for tag t<sub>j</sub>: P(w<sub>k</sub> | t<sub>j</sub>) is independent of other tags or words!<br/>

 In previous experiment you have calculated the transition and emission matrix, and now in this experiment it will be used to find the POS tag sequence for a given sentence. When we have emission and transition matrix, various algorithms can be applied to find out the POS tags for words. Some of possible algorithms are: Backward algorithm, forward algorithm and viterbi algorithm. Here, in this experiment, you can get familiar with Viterbi Decoding<br/>

 <div style="font-size:14px;">In corpus linguistics, part-of-speech tagging (POS tagging or POST), also called grammatical tagging or word-category disambiguation, is the process of marking up a word in a text (corpus) as corresponding to a particular part of speech, based on both its definition, as well as its context—i.e. relationship with adjacent and related words in a phrase, sentence, or paragraph. A simplified form of this is identification of words as nouns, verbs, adjectives, adverbs, etc.
 
 Once performed by hand, POS tagging is now done in the context of computational linguistics, using algorithms which associate discrete terms, as well as hidden parts of speech, in accordance with a set of descriptive tags. POS-tagging algorithms fall into two distinctive groups: rule-based and stochastic. </div>

 <b><u>Hidden Markov Model</u></b>
-<br><br>
+<br/><br/>
 In the mid 1980s, researchers in Europe began to use Hidden Markov models (HMMs) to disambiguate parts of speech. HMMs involve counting cases, and making a table of the probabilities of certain sequences. For example, once you've seen an article such as 'the', perhaps the next word is a noun 40% of the time, an adjective 40%, and a number 20%. Knowing this, a program can decide that "can" in "the can" is far more likely to be a noun than a verb or a modal. The same method can of course be used to benefit from knowledge about following words.
-<br><br>
+<br/><br/>
 More advanced ("higher order") HMMs learn the probabilities not only of pairs, but triples or even larger sequences. So, for example, if you've just seen an article and a verb, the next item may be very likely a preposition, article, or noun, but much less likely another verb.
-<br><br>
+<br/><br/>
 When several ambiguous words occur together, the possibilities multiply. However, it is easy to enumerate every combination and to assign a relative probability to each one, by multiplying together the probabilities of each choice in turn.
-<br><br>
+<br/><br/>
 It is worth remembering, as Eugene Charniak points out in Statistical techniques for natural language parsing, that merely assigning the most common tag to each known word and the tag "proper noun" to all unknowns, will approach 90% accuracy because many words are unambiguous.
-<br><br>
+<br/><br/>
 HMMs underlie the functioning of stochastic taggers and are used in various algorithms. Accuracies for one such algorithm (TnT) on various training data is shown here.
-<br><br>
+<br/><br/>
 <b><u>Conditional Random Field</u></b>
-<br><br>
+<br/><br/>
 Conditional random fields (CRFs) are a class of statistical modelling method often applied in machine learning, where they are used for structured prediction. Whereas an ordinary classifier predicts a label for a single sample without regard to "neighboring" samples, a CRF can take context into account. Since it can consider context, therefore CRF can be used in Natural Language Processing. Hence, Parts of Speech tagging is also possible. It predicts the POS using the lexicons as the context.
-<br><br>
+<br/><br/>
 If only one neighbour is considered as a context, then it is called bigram. Similarly, two neighbours as the context is called trigram. In this experiment, size of training corpus and context were varied to know their importance.

 Once performed by hand, POS tagging is now done in the context of computational linguistics, using algorithms which associate discrete terms, as well as hidden parts of speech, in accordance with a set of descriptive tags. POS-tagging algorithms fall into two distinctive groups: rule-based and stochastic. </div>

 Chunking of text invloves dividing a text into syntactically correlated words.
 For example, the sentence 'He ate an apple.' can be divided as follows:<br/>
 
-<img src="Exp6/a.jpg" alt="1_alt" style="height:45px; width:340px; align:center"/>
+<img alt="1_alt" src="Exp6/a.jpg" style="height:45px; width:340px; align:center"/>
 
 <div style="font-size:15px;">
 Each chunk has an open boundary and close boundary that delimit the word groups as a minimal non-recursive unit. This can be formally expressed by using IOB prefixes.

 					<p class="text-h3-darkblue-bold">Q1. What are Virtual labs?</p>
 <p> Virtual Labs are intended to augment the learning of science and engineering subjects through performing experiments. The experiments are designed either as simulations or as remote triggered. A remote triggered lab allows a user to connect to real equipment using a web browser. There are currently around 150 and labs and 1500 experiments at various stages of development and deployment. They are currently hosted at vlabs.ac.in.
 
 Virtual Labs is an initiative of Ministry of Human Resources, India.
 </p>
 <p class="text-h3-darkblue-bold">Q2. What are the objectives of the Virtual Labs?</p>
-<p>The broad objectives of the ‘Virtual Lab’ as stated in  website are:<br>
-1. To provide remote access to Labs in various disciplines<br> 
-2. To arouse curiosity in students and  help them learn  concepts through remote experimentation  <br>
-3. To provide a complete ‘Learning Management System’ (LMS) around the Virtual labs –<br>
-a. access to web-resources, videos,  animated demonstrations and <br>
-b. self evaluation <br>
-4. To provide access to resources available  to only a limited number of users due to constraints of time and physical locations.<br>

+<p>There are two types of Virtual Labs:<br/>
 <b>Simulation Based Virtual Labs:</b>  In these Virtual Labs, the experiments
 are modeled using mathematical equations.  The simulations are carried out
 remotely at a high end server, and the results are communicated to the student
 over the internet.  This class of Virtual Labs, at best, mimics the real-world
 scenarios/experiments.  Simulation based Virtual Labs are scalable and can
-cater to a large number of simultaneous users.<br><b>Remote Triggered Virtual Labs:</b> In these Virtual Labs, the actual experiments are triggered remotely.  The output of the experiment (being conducted remotely) is communicated back to the student over the internet.  This class of Virtual Labs, gives the student the output of real-time experiments.  Remote Triggered Virtual Labs are difficult to scale and can cater to a limited number of users.  Typically, time-slots are booked before conducting such experiments.</p>

 <p class="text-h3-darkblue-bold">Q12. Does the  Virtual Lab provide the  LMS that the objectives mention?</p>
 <p>Virtual Lab project provides a complete Leaning Management System. For most users, Virtual Lab provides all the relevant material at one place including the Objectives of the Experiment, Procedure, Lab manual, Pre- and Post-experiment quizzes, additional Lab resources, in addition to the Virtual Lab experiment. Most labs also have an associated question bank.</p>
 <p class="text-h3-darkblue-bold">Q13. How do I register for using the Virtual Labs? </p>

On the other hand, some of the simulation virtual labs require registration for which the user can go to the respective website do a one-time registration.<br/>
 <b>Remote Triggered Labs:</b> To access a remote triggered lab, a user has to book a slot. For booking a slot, you have to register yourself first and then book a slot from the slot chart. All the available /booked slots can be viewed on this chart. Once a request for slot-booking is made, all the information regarding the user id, password and the slot booked will be sent to the user’s email address provided by the user at the time of registration. Once registered, a user can login using the same credentials every time. This registration has to be done by the user separately for each of the remote triggered virtual labs.</p>	 
 <p class="text-h3-darkblue-bold">Q14. What benefit will Virtual Lab provide?</p>
 <p>Virtual Lab is a complete Learning Management System. All the relevant information including the theory, lab-manual, additional web-resources, video-lectures, animated demonstrations and self-evaluation are available at a common place. Virtual Labs can be used in a complementary fashion to augment the efficacy of theory-based lectures. Small projects can also be carried out using some of the Virtual Labs. Virtual Labs can be effectively used to give lab-demonstrations to large class.</p>
