Abstract
Data growth has seen an exponential acceleration with the advent of computer and network, which have imparted the digital form to data. Data can be classified into three categories: Unstructured data, Semi-structured data and structured data. Text Mining concerns extraction of relevant information, knowledge or patterns from sources that are in Unstructured or Semi-structured form. This project entitled “Transforming Digital Unstructured and Semi-structured Data into Structured Data with the Aid of IE and KDT” demonstrates a framework for text mining using a learned information extraction system aided with KDT (Knowledge Discovery from Text) principles. The functionality of this project is concentrated over the integrated result of IE (Information Extraction) module, KDT (Knowledge Discovery form Text) module and Standard Protocols module. Pre-processing is employed for transforming unstructured data or Semi-structured data such as HTML documents, text documents, and documents with .doc, .docx or .pdf extensions into a feasible format of data which is then mined for interesting relationships. Standard Protocols are defined for discovery of additional information’s from input sources. For Example, consider if information extraction system has managed to extract skills like “HTML” and “DHTML” from a computer job posting but could not find “XML” in the document, in such cases relationships can be mined through predefined derivations which are framed in the standard protocols module. In addition, rules mined from the database extracted from a corpus of texts are used to predict additional information that could be extracted from future input documents, thereby improving the recall of the underlying extraction system. Results are presented by applying these techniques to a corpus of computer job announcement from an internet news group.
