Twitter Sentiment Analysis using Distributed Word and Sentence Representation

An important part of the information gathering and data analysis is to find out what people think about, either a product or an entity. Twitter is an opinion rich social networking site. The posts or tweets from this data can be used for mining people's opinions. The recent surge of activity in this area can be attributed to the computational treatment of data, which made opinion extraction and sentiment analysis easier. This paper classifies tweets into positive and negative sentiments, but instead of using traditional methods or preprocessing text data here we use the distributed representations of words and sentences to classify the tweets. We use Long Short Term Memory (LSTM) Networks, Convolutional Neural Networks (CNNs) and Artificial Neural Networks. The first two are used on Distributed Representation of words while the latter is used on the distributed representation of sentences. This paper achieves accuracies as high as 81%. It also suggests the best and optimal ways for creating distributed representations of words for sentiment analysis, out of the available methods.Comment: 8 pages, 5 figures, 6 table

Role of social science research in the integrated development and management of marine fisheries

The importance of fisheries in the national economy needs no emphasis. The reasons for the development of fisheries In India are the same as In many of the Third World countries: the need to a) increased fish production, b) secure Income and foreign exchange, and c) provision of employment opportunities. This paper intends 1. to review and examine the current pace of social science research In marine fisheries, 2.to evaluate the performance of fishery policy and planning in India, and 3.to emphasise the need for sustained contribution of social science research for the integrated development and management of marine fisheries.it Is found that the pace of social science research in the fisheries sector has hither to been rather limited. Excepting a few studies sponsored by Government and also some pioneering attempts by individual social scientists, systematic analytical research Is lacking. The efforts of fishery policy and planning In India, so far, resulted In realising some of the national objectives in terms of growth of marine fish production and exports. information about the improvement of the socio-economic conditions of fishermen is scanty. Due to absence of social science research interms of penodlcal evaluation of planning strategy, implementation mechanism and the resultant benefits, the desired results could not be achieved. Therefore, it is necessary to concentrate or problem oriented researching to Integrate the same with fisheries planning, and also to strengthen the social science research capacity for better development and management of marine fisheries

A Process Oriented Approach to Waiting Line Management in a Large Pilgrimage Center in India: A Case Study

This article documents an innovative approach to manage waiting line in the largest pilgrimage center in the world. By a judicious combination of process orientation and advances in Information Technology, the pilgrimage center’s management has been able to dramatically change the pilgrims waiting experience. The pilgrimage location under study is Tirumala located in Andhra Pradesh state in India. The number of visitors to this important location has been steadily increasing over time. As of 2005, the location attracted approximately 16 million visitors a year. The primary objective of a pilgrim visiting Tirumala is to have darshan of the principle deity in the temple. The secondary objectives include tonsure (shaving head as a mark of respect), offering donations, prasad collection, local sight seeing and shopping. The immense popularity of the temple and its location poses significant challenges to the management of the system. This temple is a tradition bound Institution. Therefore, some alternatives to resolve pilgrim waiting time are feasible and some are not. There are some hard constraints which may not stand the test of logic. The ability to manage the traffic volume is a function of processing rate (darshan duration) at the temple and darshan time available per day. This case study is an example of improving operational effectiveness by using formal management methods in addressing an important real life problem in an under researched area.

Hypohidrotic Ectodermal Dysplasia with total anodontia: a case report

Ectodermal dysplasia is a hereditary disorder that occurs as a consequence of disturbances in the ectoderm of the developing embryo. The triad of nail dystrophy, alopecia or hypotrichosis and palmoplantar hyperkeratosis is usually accompanied by a lack of sweat glands and a partial or complete absence of primary and/ or permanent dentition. A case report illustrating the prosthetic rehabilitation of a seven year old boy with hypohidrotic ectodermal dysplasia associated with total anodontia is presented

Spectra of some new graph operations and some new classes of integral graphs

In this paper, we define duplication corona, duplication neighborhood corona and duplication edge corona of two graphs. We compute their adjacency spectrum, Laplacian spectrum and signless Laplacian. As an application, our results enable us to construct infinitely many pairs of cospectral graphs and also integral graphs. Keywords: Duplication corona, Duplication edge corona, Duplication neighborhood corona, Cospectral graphs, Integral graphs

FPGA based Security Login System using GSM with OTP Generation

Security of system is major concern in this age of high-tech infrastructure. In today\u27s materialistic world, security holds an in dispensable place. Security in every aspect is highly desirable may be at home or at office etc. as thefts and robberies are increasing day by day. To overcome this security threat, a security system has been proposed using GSM technology, by generating One Time Password and implementing in FPGA. As FPGAs offer all of the features needed to implement most complex designs. This security system activates, authenticates and validates the user and then unlocks the system. This project attempts to create security login systemwhere the user is granted access if he enters the correct predefined password and is denied access if he enter the wrong password. When password is entered GSM gets activated and send SMS to user\u27s mobile phone, after authentication random OTP is generated and should be verified such that the system gets accessed. In every 3 minutes this OTP verification code will change and is valid for 3 minutes. The outcome of each and all would be available in the LCD of the Spartan 3E board. VHDL codes are used to design this system using Xilinx ISE 9.2i

Seaweed resources of the Tuticorin-Tiruchendur coast, Tamil Nadu, India

The southern coast of Tamil Nadu (Mandapam to Kanyakumari) supports luxuriant growth of economic seaweeds. The entire indigenous phycocoUoid industry of the country gets the raw material from this region and during the last two decades, due to indiscriminate harvesting, there has been over-exploitation of the resource. The present paper deals with survey conducted in the first sector from Tuticorin to Tiruchendur during December 1986—March 1987. In this study 58 species of marine algae were recorded of which 7 belong to Chlorophyta, 12 to Phaeophyta and 39 to Rhodophyta besides 3 species of seagrasses namely Cymodocea seiriilata, Halophila ovalis and //. ovata within 650 sq. km area surveyed. The total standing crop of the seaweeds was estimated at 9,100 tonnes (wt.). The estimates for the dominant species are Dictyota maxima 530 t, Sargassum tenerrium 640 t, D. bartayresiana 8601, Selieria rebusta 2,0901 and Hypnea valemiae 2,4301. The seaweed potential for commercial exploitation has been briefly discussed
