Nowadays many people exploit images to represent and symbolize information by converting an image into digital form where different operations are performed on it for the extraction of information though the techniques of image processing. The important information that extracted from images is furthermore popular. Image recognition be a vital analysis half for wide applications. Within the comparative pattern recognition field of pc, the one difficult task is actual automatic recognition of individual human handwriting.Even though, the variances do not origin any struggle to human. Yet, but it is further complicated to instruct computers towards recognize wide-ranging handwriting. Intended for image recognition difficulty such since handwritten categorization, it is extremely significant to create away how information or data are represent in images. The information at this point is not the pixels row, but the image features have high intensity representation. View More The E-evaluation is an innovative idea within the playing field of didactics in which the aim is towards enables automatic evaluation of the exam papers with support of computer recognition system and artificial intelligence, particularly OCR and image perceptive. E-evaluation software that a system enables the automatic evaluation of handwritten examination answer scripts through the examiner upon a computer monitor relatively than analysis of paper document. The e-evaluation system is enhanced for the examination session, since it perform segmentation though the answer scripts into an individual task, and distributes task to the certain examiners, specific in the domain which evaluate the task and then send to the Examination panel and also verify the assessment, gather the statistics and the evaluation result. The computer aid evaluation is an easy task. In form of electronic it simply compares the result to key answers. The scanned answer scripts are processed to recognize the marks. The automatic evaluation task is difficult because of the proper set of solutions would be infinite. The inaccurate answer would be graded with fewer score. The problems may occur during mathematical formula, for this pattern recognition technique is used. The mathematical formula/expression recognition works by individual symbol detection and structural analysis though image segmentation and pattern recognition. And the standard approach acknowledged from OCR for recognition.
Character recognition is a theme of exhaustive analysis for an extended time period. Whereas the printed text recognition is considered mostly as a solved problem today, handwritten text recognition remains a difficult task because of elevated variability in different people handwriting .The system for identifying text though answer scripts and also evaluate marks intended for every small answer on the base of acquired knowledge besides a model. OCR tool is use to take out the handwritten text, where NLP and neural network used for extraction of keywords though human evaluation dataset samples of answer paper and keys. The system also evaluates the score based upon similarity measure of sentences. The dataset contains answer and the evaluated mark .The evaluation method to calculate the score for every answer which is written by the students, anywhere the appliance are trained based upon datasets. Intended for each answer creature entered was significant to recompense point base taking place the practice of word and the importance. The evaluation will perform though the approach by means of Kaggle dataset or Kaggle Short Answer dataset . In  the training and processing of exam answer scripts of individual person to attain the evaluations of answer script by machine learning technique through the assist of back propagation algorithms and neural network. Machine learning technique of introduce computing to the system wherever the system start to find out because it work and therefore become a set of reasonable over the time. By means of assist though neural network many neurons would build that have more information and logics that needed for the system. The algorithm of back propagationincreases the efficiency of neurons. Neural network used towards scanning and make sure the checking of the examination papers of individual student and evaluate the answers based on the data fed into the system. Back propagation would track answer beside student for similar answers and exclude some errors incurred though the system during the process of evaluation. The Handwritten Short Answer analysis System is an automatic small answer analysis system that capable of identify the text in answer scripts and evaluate mark for every small answers supported earlier information acquire besides model. Within the system, Optical Character Recognition tool are accustomed extract the written texts. Natural language process is employed to take out keywords as of human evaluate model dataset of written answer key and answer paper. The projected models evaluate scores supported circular function sentence similarity measure . OCR used towards change of scannedpaper into text and it can be edited. The converted document using OCR occupies not as much of space than the image. The NLP used for sentence to confirm the semantic formation. Ontology will match words with keywords in the paragraph based on the matching evaluation will be performed . In  Evaluation technique for subjective answer proposed algorithm performs Tokenizing vocabulary and sentence, Chunking, Part of words tagging, Lemmatizing word, Chinking and Word netting toward assessment of individual answer and also it provides the semantic connotation of context. This System divided by main two modules. The module one is data extraction from the image which is scanned and organizing the data in an appropriate manner extracting and the module two is applying NLP and Machine Learning towards the text retrieval and to provide marks. The digit recognition is classification difficulty, the hypothesis firstly compare classification result of numerous algorithm though machine learning upon MNIST dataset, and subsequently select the convolution neural network through the maximum recognition accurateness rate intended for method implementation. at last, the method on behalf of correcting exam papers is achieve all the way through image uploading, image transformation, image acquisition, digit pre-processing, classification though convolution neural network and the answer comparison score. The convolutional neural network is applied towards written digit recognition for feature extraction deformations although native field and pooling .  Presents software frame with the aim of assist teachers during correction task related to mathematical exercises with some degrees of mathematical contents. This system designed a particular workflow and position of convention to facilitate will automatically analyze the student assignments and also check whether they enclose rational mathematical in sequence associated to exact fields. The set of tools would also take into relation corresponding expressions. Within the order towards the check for coherence, extremely configurable and without problems and the teacher designed editable content-checking rules which submitted near correction mechanism. Detects the flaw and information gaps by identifying central part concepts the gaps are detected. Where the flaws are identified besides the segmenting process, aligning and the student answer analysis task . The ontology of graphemes aims a character recognition technique which expressed throughout the formation of ontology so as to represents the contented text or document written automatically or manually. This ontology would transform the picture-version of text into a representation of spatial relationships and concepts. This paper presents typographical depiction of processed and analyzed document or text by representing ontology by the set of concept which represents the grapheme of the character by denoting the position or the document towards localization . To extract specific space of the task the bitmaps are used to process and also the analysis task is performed with the support of image process and also the analysis.
