Prevalent use of human language in computer systems and language oriented document processing, especially in the web, caused creating the need of designing mechanisms for developing natural languageprocessing. In this paper, a survey in Natural languageprocessing Laboratory has been done and a proposed framework for its development is suggested. Achieving this goal, the specifications, structures and activities of available Natural languageprocessing Laboratories have been reviewed and valuable results are obtained. Afterward, a proposed framework is established. this framework introduces requirements of Laboratory in a structural way that providing solutions for it any clear plan in NLP Laboratories. Finally, according to National requirements of Iran and characteristics of Persian language, a Natural languageprocessing Laboratory in discussed framework is designed. the activities of this laboratory includes basic tasks like creating linguistic resources (Corpora, Bilingual corpora, Lexicon, etc), test datasets, developing Natural languageprocessing System's Evaluation Framework, development of basic tools (Parser, POS-tagger, etc), research tasks like defining areas for universities, and services such as application development, natural languageprocessing system evaluation, and granting of the appropriate certificates.

this article demonstrates a new approach to measuring English readability applying techniques from natural languageprocessing and informationtheory. We attempt to regard reading process as a process of informationprocessing and transferring. And then we apply statistical language modeling technique and informationtheory to compute the information of text passage, based on which the readability measuring models are trained. the results of experiments show that this new approach holds a higher correlation value (0.849) than the traditional formula such as ARI formula (0.540) withthe grade level of test data. And the new approach can take the word sequence, reader's language characteristics and environment into account when measuring readability, which cannot be performed by the previous formulas.

Social media have received more attention nowadays. Public and private opinion about a wide variety of subjects are expressed and spread continually via numerous social media. Twitter is one of the social media that is gaining popularity. Twitter offers organizations a fast and effective way to analyze customers' perspectives toward the critical to success in the market place. Developing a program for sentiment analysis is an approach to be used to computationally measure customers' perceptions. this paper reports on the design of a sentiment analysis, extracting a vast amount of tweets. Prototyping is used in this development. Results classify customers' perspective via tweets into positive and negative, which is represented in a pie chart and html page. However, the program has planned to develop on a web application system, but due to limitation of Django which can be worked on a Linux server or LAMP, for further this approach need to be done.

the concept of "Stopword" was first introduced by H.P. Luhn in 1958. In Natural languageprocessing (NLP), Stop word is a common word that is neither indexed nor searchable in a computer search engine. Example of stop words are 'a', 'the', 'is' etc. Removing stopword is Pre-processing step in majority of NLP applications, including IR (information Retrieval) and TC (Text Classification). Some of the benefits of removing stop word are - decrease in size of corpus by 35-45%, improvement of efficiency and accuracy of the text mining applications thus helping in reduction of time and space complexity of overall application. In this paper, we discuss the various major stopword identification techniques used by the researchers in last few decades, for Indian language and Non-Indian languages. Also, we present a survey of methods used for stopword list generation withtheir characteristics. We have also mentioned the effect of various stopword removal techniques applied on TC and IR application domains. A comprehensive list of resources publicly available for static stop words in various languages is also given for quick reference.

In this paper we first review existing approaches of XML web Services for process monitoring and control, and then provide the limitation under consideration of existing approaches. We propose a framework for implementation of OPC1 web Service based on SOA (Service-Oriented Architecture), OPC UA (Unified Architecture) technology, and OOD (Object-Oriented Design). In order to overcome the limitation of the performance of XML web Services, the binary data representation is to use in the proposed framework. Our framework obviously makes it easy to deploy, maintain and is effective for applying to the control and monitoring systems. In addition, the performance analysis and discussion demonstrate that our system has a good performance and is feasible in order to apply to the distributed data acquisition and monitoring systems.

We present a demonstrating web application for biomedical imaging and visualization, addressing its capability of implementing comprehensive image processing algorithms at the server side where proprietary datasets reside and direct access to them by client-side applications is restricted. the main technical challenge is to make the functionality of the dedicated imaging and visualization programs (usually compiled from a native programming language such as C++) publicly available via a web based interface. Accessing information of the original image data and algorithmic details should be hidden, thus scripts executed by the webpage browser should be avoided. In this regard, we propose a solution based on the *** framework. Managed codes in C# are developed for web controls, server-side GUI and relational database management;whereas unmanaged server-dependent imaging programs are invoked from within the managed programs. the advantages of such a web application include (a) high security of the proprietary data which always a primary consideration in deployment of a networked system, (b) thin-client strategy in which heavy computing tasks are completed on the dedicated server with high-performance hardware, and (c) less demand for network bandwidth as only the rendering results instead of multiple high-dimensional datasets need to be transferred. the proposed approach is believed to be beneficial for building the web-based Laboratory information System (LIS) and Radiology information System (RIS).

One of the rising fields of research are hand gesture recognition. Being an important part of non-verbal interaction is a critical part of our everyday life. Hand management recognition systems allow us to communicate withthe machine, which is more familiar to the human being, creative, normal, user-friendly. Hand gesture recognition covers a wide range of applications including contact withthe human machine, sign language, immersive game technology etc. To perform this we have implemented a method of hand recognition and extraction of features by means of a web camera in real time. the picture is captured in this method through the system's webcam. the initial processing of the input image and thresholding are used to remove image noise and smooththe image. Following this, apply region filling in the gesture or object of interest to fill holes. the "HU moments" are used for feature extraction and classification using KNN algorithm. this helps in improving the classification though machine learning and recognition step. We have tested 43 gestures which include 26 gestures of English alphabets and achieved a confidence of 99.9%
