ABSTRACT In this paper, we demonstrate the efficacy of a POS annotation method that employed the services of two automatic approaches to assist POS tagged corpus creation for a novel language in NLP. The two approaches are cross-lingual and monolingual POS tags projection. We used cross-lingual to automatically create an initial ‘errorful’ tagged corpus for a target language via word-alignment. The resources for creating this are derived from a source language rich in NLP resources. A monolingual method is applied to clean the induce noise via an alignment process and to transform the source language tags to the target language tags. We used English and Igbo as our case study. This is possible because there are parallel texts that exist between English and Igbo, and the source language English has available NLP resources. The results of the experiment show a steady improvement in accuracy and rate of tags transformation with score ranges of 6.13% to 83.79% and 8.67% to 98.37% respectively. The rate of tags transformation evaluates the rate at which source language tags are translated to target language tags.

ISOLATING WORD LEVEL RULES IN TAMIL LANGUAGE FOR EFFICIENT DEVELOPMENT OF LANGUAGE TOOLS Suriyah M, Aarthy Anandan, Anitha Narasimhan and Madhan Karky Karky Research Foundation, India
ABSTRACT With the advent of social media, the amount of text available for processing across different natural languages has become enormous. In the past few decades, there has been tremendous increase in the number of language processing applications. The tools for natural language computing of various languages are very different because each language has its own set of grammatical rules. This paper focuses on identifying the basic inflectional principles of Tamil language at word level. Three levels of word inflection concepts are considered – Patterns, Rules and Exceptions. How grammatical principles for word inflections in Tamil can be grouped in these three levels and applied for obtaining different word forms is the focus of this paper. These can be made use of in a wide variety of natural language applications like morphological analysis, morphological generation, word level translation, spelling and grammar check, information extraction etc. The tools using these rules will account for faster operation and better implementation of Tamil grammatical rules referred from [த ொ ல் த ொ ப் பியம் | tholgaappiyam] and [ நன் னூல் | nannool] in NLP applications.

CITIZENSHIP ACT (591) OF GHANA AS A LOGIC THEOREM AND ITS SEMANTIC IMPLICATIONS NakpihIreneous Callistus Department of Mathematics and Computing, St. John Bosco’s College of Education, Navrongo, Ghana
ABSTRACT This paper presents excerpts of the natural text of the Citizenship Act of the Republic of Ghana, ACT 2000 (591), as a logic theorem in First Order Logic (FOL) language. The formalism of this piece of law is done to allow for semantic analysis of the text by machines. The results of this research also deals with the problem of ambiguities in the legal text, and reveals the semantic consequence of the natural construction or textual structure of the piece of law; one major problem of the semantics of legal text has been the problem of ambiguities, which largely affects interpretations that are alluded to legal statements. Some constructed sentences sometimes do not reflect the semantic intentions of the composers of the sentences, due to inherent ambiguities or technical faults in the structure of some parts of the statements. The formalism of the Act in this paper provides logical proofs and deductions which are asserted to establish clarity and to reveal semantic errors, or otherwise preserve the semantic intentions of the Act.

ABSTRACT Manipuri is both a minority and morphologically rich language with genetic features similar to Tibeto Burman languages. It has Subject-Object-Verb (SOV) order, agglutinative verb morphology and is monosyllabic. Morphology and syntax are not clearly distinguished in this language. Natural Language Processing (NLP) is a useful research field of computer science that deals with processing of a large amount of natural language corpus. The NLP applications encompass E-Dictionary, Morphological Analyzer, Reduplicated Multi-Word Expression (RMWE), Named Entity Recognition (NER), Part of Speech (POS) Tagging, Machine Translation (MT), Word Net, Word Sense Disambiguation (WSD) etc. In this paper, we present a study on the advancements in NLP applications for Manipuri language, at the same time presenting a comparison table of the approaches and techniques adopted and the results obtained of each of the applications followed by a detail discussion of each work.

SARCASM AS A CONTRADICTION BETWEEN A TWEET AND ITS TEMPORAL FACTS: A PATTERNBASED APPROACH
Santosh Kumar Bharti and Korra Sathya Babu Department of Computer Science and Engineering, National Institute of Technology, Rourkela, Odisha, India
ABSTRACT In the context of Indian languages, sarcasm detection in Hindi is a tedious job as it is rich in morphology and complex in structure. The annotated resources for sarcastic Hindi sentences are almost negligible for machine learning analysis. Here, we propose a pattern-based framework for sarcasm detection in Hindi tweets. It has been observed that a tweet is sarcastic if it contradicts its temporal facts intentionally. The temporal fact is a collection of time-dependent facts which may change over the period. We used Hindi news with timestamp as a corpus of temporal facts. The timestamp describes the fact period of any entity. In this research, a temporal fact is represented as a pair. To form a pair, one need to extract triplets i.e. subject, verb and object for every sentence. Next, a key is formed using subject and verb together. The value is formed using object and timestamp together. To predict the sarcastic tweet; one needs to extract the triplets from input tweet and form a pair. Now, the pair of the input tweet is mapped with related pair in the corpus of temporal facts and are checked if they coincide. If they contradict, the input tweet is considered as sarcastic. The achieved accuracy of the proposed approach outperforms the state-of-the-arts techniques for Hindi sarcasm detection as it attains an accuracy of 82.8%.

ABSTRACT Sentiment analysis has been performed in different languages and in various domains, such as movie reviews, product reviews and tourism reviews. However, not much work has been done in the area of books considering the high availability of book reviews on Hindi blogs and online forums. In this paper, a scorebased sentiment mining system for Hindi language is discussed, which captures the sentiment behind the words of book review sentences. We conducted three experiments using scores from the HindiSentiWordNet (H-SWN), first using parts-of-speech tags of opinion words to extract their potential scores. Then, we focused on word-sense disambiguation (WSD) to increase the accuracy of system. Finally, the classification results were improved by handling morphological variations. The results were validated against human annotations achieving an overall accuracy of 86.3%. The work was extended further using Hindi Subjective Lexicon (HSL). We also developed an annotated corpus of book reviews in Hindi.

SENTIMENT ANALYSIS OF MIXED CODE FOR THE TRANSLITERATED HINDI AND MARATHI TEXTS Mohammed Arshad Ansari and Sharvari Govilkar Department of Information Technology, Pillai College of Engineering, New Panvel, Navi Mumbai, Maharashtra, India 410206
ABSTRACT The evolution of information Technology has led to the collection of large amount of data, the volume of which has increased to the extent that in last two years the data produced is greater than all the data ever recorded in human history. This has necessitated use of machines to understand, interpret and apply data, without manual involvement. A lot of these texts are available in transliterated code-mixed form, which due to the complexity are very difficult to analyze. The work already performed in this area is progressing at great pace and this work hopes to be a way to push that work further. The designed system is an effort which classifies Hindi as well as Marathi text transliterated (Romanized) documents automatically using supervised learning methods (KNN), NaĂŻve Bayes and Support Vector Machine (SVM)) and ontology based classification; and results are compared to in order to decide which methodology is better suited in handling of these documents. As we will see, the plain machine learning algorithm applications are just as or in many cases are much better in performance than the more analytical approach.

ABSTRACT Information retrieval is becoming an intricate part of every domain. Be it in acquiring data from various sources to form a single unit or to present the data in such a way that anyone can extract useful information and hence used in data analysis, data mining etc. This arena has gained much importance in the recent years because as of today we are exploded with various kind of information from the real-world. The growing importance of research data and retrieving the intelligent data are the main focus for any business today. So coming years this is a field where major work need to be done. We have focused here to implement a system for information retrieval from the webpages using Natural Language Processing (NLP) and have shown to getting better results than the existing system. Webpages is a home to huge amount of information from various entities in the real-world. Here we have designed a system for information retrieval technique for web using NLP where techniques Hierarchical Conditional Random Fields (i.e. HCRF) and extended Semi-Markov Conditional Random Fields (i.e. Semi-CRF) along with Visual Page Segmentation is used to get the accurate results. Also parallel processing is used to achieve the results in desired time frame. It further improves the decision making between HCRF and Semi-CRF by using bidirectional approach rather than top-down approach. It enables better understanding of the content and page structure.

ABSTRACT Word segmentation is a basic problem in natural language processing. With the languages having the complex writing system like the Khmer language in Southern of Vietnam, this problem really very intractable, posing the significant challenges. Although there are some experts in Vietnam as well as international having deeply researched this problem, there are still no reasonable results meeting the demand, in particular, no treated thoroughly the ambiguous phenomenon, in the process of Khmer language processing so far. This paper present a solution based on the syllable division into component clusters using two syllable models proposed, thereby building a Khmer syllable database, is still not actually available. This method using a lexical database updated from the online Khmer dictionaries and some supported dictionaries serving role of training data and complementary linguistic characteristics. Each component cluster is labelled and located by the first and last letter to identify entirety a syllable. This approach is workable and the test results achieve high accuracy, eliminate the ambiguity, contribute to solving the problem of word segmentation and applying efficiency in Khmer language processing.

A NOVEL APPROACH FOR INFORMATION RETRIEVAL TECHNIQUE FOR WEB USING NLP Rini John and Sharvari S. Govilkar Department of Computer Engineering of PIIT Mumbai University, New Panvel, India
ABSTRACT Webpages are loaded with vast and different kinds of information about the entities in the real-world. Information retrieval from the Web is of a greater significance today to get the accurate queried data within the desired time frame which is increasingly becoming difficult with each passing day. Need to develop a system to solve entity extraction problems from the web as compared to the traditional system. It’s critical to have a clear understanding of natural language sentence processing in the web page along with the structure of the web page to get the correct information with speed. Here we have proposed approach for information retrieval technique for Web using NLP where techniques Hierarchical Conditional Random Fields (i.e. HCRF) and extended SemiMarkov Conditional Random Fields (i.e. SemiCRF) along with Visual Page Segmentation is used to get the accurate results. Also parallel processing is used to achieve the results in desired time frame. It further improves the decision making between HCRF and Semi-CRF by using bidirectional approach rather than top-down approach. It enables better understanding of the content and page structure.
