| Abstract | Extracting information from unstructured text data is a compute-intensive task. The performance of general-purpose processors cannot keep up with the rapid growth of textual data. Therefore we discuss the use of FPGAs to perform large scale text analytics. We present a framework consisting of a compiler and an operator library capable of generating a Verilog processing pipeline from a text analytics query specified in the annotation query language AQL. The operator library comprises a set of configurable modules capable of performing relational and extraction tasks which can be assembled by the compiler to represent a full annotation operator graph. Leveraging the nature of text processing we show that most tasks can be performed in an efficient streaming fashion. We evaluate the performance, power consumption and hardware utilization of our approach for a set of different queries compiled to a Stratix IV FPGA. Measurements show an up to 79 times improvement of document-throughput over a 64 threaded software implementation on a POWER7 server. Moreover the accelerated system's energy efficiency is up to 85 times better. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
