The vast majority of copied documents generally consist of text, and the copy quality mostly depends on the text’s reproduction quality. A new technique to enhance dark text on light background of scanned mixed mode documents (containing text, graphics and photo) is presented to improve copy quality. This technique incorporates various image processing filters that enhance dark text without dis...

Text classification is the process of classifying documents into predefined categories based on their content. Existing supervised learning algorithms to automatically classify text need sufficient documents to learn accurately. This paper presents a new algorithm for text classification that requires fewer documents for training. Instead of using words, word relation i.e association rules from...

In recent years, production of text documents has seen an exponential growth, which is the reason why their proper classification seems necessary for better access. One of the main problems of classifying text documents is working in high-dimensional feature space. Feature Selection (FS) is one of the ways to reduce the number of text attributes. So, working with a great bulk of the feature spa...

Text categorization is the process of sorting text documents into one or more predefined categories or classes of similar documents. Differences in the results of such categorization arise from the feature set chosen to base the association of a given document with a given category. Advocates of text categorization recognize that the sorting of text documents into categories of like documents r...

The information available on web pages mostly contains semi-structured text documents which are represented either in XML, or HTML, or XHTML format that lacks formatted document structure. The document does not discriminate between the text and the schema that represent the text. Also the amount of structure used to represent the text depends on the purpose and size of text document. No semanti...

Text classification is one of the important research issues in the field of text mining, where the documents are classified with supervised knowledge. In literature we can find many text representation schemes and classifiers/learning algorithms used to classify text documents to the predefined categories. In this paper, we present various text representation schemes and compare different class...

Punjabi Text Classification is the process of assigning predefined classes to the unlabelled text documents. Because of dramatic increase in the amount of content available in digital form, text classification becomes an urgent need to manage the digital data efficiently and accurately. Till now no Punjabi Text Classifier is available for Punjabi Text Documents. Therefore, in this paper, existi...
