| Abstract | Nowadays found some micro-blog commercial extraction algorithm only considering the relationship between the key words and the number of it appearing in texts, and ignoring the key words' distribution in a certain category, which leads the decreased accuracy problems of micro-blog commercial word extraction. To solve this problem, the application of TF-IDF algorithm in words weight calculation was researched in this paper. Combining the relevant knowledge of information theory and analyzing the distribution of keywords within a class, the article proposed improving TF-IDF algorithm and applying it in term weight calculation. To test the feasibility of the improved algorithm, this paper initially classified the massive micro-blog information into certain types, and then used improved TFIDF algorithm to calculate term weight among the categories, and, this calculation was realized under the Hadoop Distributed framework. The experiment results demonstrated that in the application of micro-blog commercial word extraction, the improved TF-IDF algorithm is effective and feasible. Compared with traditional algorithms, the improved algorithm greatly improved accuracy. In addition, the data processing speed has greatly improved under Hadoop framework. |

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.
