Govt. rules deprived Chandrayaan's team from Padma Shri

Despite Chandrayaan-1 being the first lunar mission of India, the scientists and engineers engaged in the mission remained unrecognised with no mention in the list of Padma Shri awardees.

The reason for their work being overlooked is a rule framed by the government a few years ago stipulating that those attached to government organisations like ISRO and Department of Atomic Energy (DAE) will not be entitled to any "government-backed" awards, like the prestigious Padma awards.

rule. The Government now wants to revise this decision keeping in view the fact that it will be counter productive in terms of morale of those who labour in official agencies at salaries that are much less than in the private sector and where national pride is a big motivator.

The controversial decision comes at a time when government wants to stem brain drain of scientists and engineers to foreign organisations like NASA and woo them back to India with better terms than before and by rewarding good performance. Yet, if official recognition is itself banned while Padma awards are awarded to achievers of Indian origin in foreign countries, Indian establishments are bound to feel rather left out.

Latent Semantic Indexing (LSI)

Latent Semantic Indexing (LSI) is the indexing and retrieval method, the mathematical technique called singular value decomposition (SVD) to identify the relationships between the terms and concepts contained in an unstructured content. LSI is the word used in that environment based on the principles usually has a similar meaning. If you find an LSI - indexed databases, search engines look at the value of the content are calculated for each word, and returns document, considers the most appropriate investigation. Since the two documents can be semantically very close, even if they disagree with certain keywords, LSI is not necessary an exact match to return useful results. If a simple keyword search will fail and there is no exact match, LSI will often return relevant documents do not contain all of the keywords.
