For each query term t 1. retrieve lexicon entry for t 2. note ft and address of It (inverted list) 2. (IR), Content-Based Image Retrieval (CBIR), and Natural Language Processing (NLP). Information retrieval is the activity of obtaining information resources relevant to an information need from a collection of information resources. Information retrieval, NLP, Entity Extraction, Visual Page Segmentation (VIPS), Semi-CRF (Semi-Markov conditional random fields), HCRF (Hierarchical conditional random field) and Parallel processing. IR typically advances over four broad stages viz., identification of text types, document preprocessing, document indexing, and query processing and matching the same to documents. Alan Turing’s paper Computing Machinery and Intelligence is believed to be the first NLP paper. However the question is how to combine NLP and several semantic technologies to help users in creating knowledge, analyzing and renewing output but assigning the labels becomes a task. Natural Language Processing 1 Language is a method of communication with the help of which we can speak, read and write. “Natural language processing (NLP) is a field of computer science, artificial intelligence, and linguistics concerned with the interactions between computers and human (natural) languages. A layered approach to information retrieval permits the inclusion of multiple search en- gines as well as multiple databases, with a natural language layer to convert English queries for use by the various search en- gines.
