Mahadasara 2007-08

‘Maharaja Institute of Technology, Mysore’ organized is first annual day function called Mahadasara on 26-04-08. That was a beautiful evening function in the college campus. Chief guest Mr.Ananth Koppar inaugurates the function and he spoke about MIT and its background. Dr.G.Hemanth Kumar delivered the presidential speech as well as principal Dr.K.B.Boraiah also spoke about the college function. All the guest members and staff members including secretary Dr.Y.T.Krishnegowda & Dr.B.G.Naresh Kumar distribute the prizes to winners of cultural and sports competitions, which was held from 17-04-08 to 26-04-08. Students were actively participated in the competitions & their cultural programme was an excellent and audience enjoyed with them. Totally Mahadasara made the history in MIT

Summer days

Summer day morning and evening are very beautiful because, it’s the time of an attractive Sunrise & sunset.

Competition World

Today we living in competition world here we can’t neglect any thing. Yesterday I saw a TV program of children’s dance & all the participants performed very well and judges were struggled to judge them. In an entertainment program has the competition, think it other fields in the whole world. Ensure the competition world & get ready to participate.

Librarians work

Librarianship seems to the world as simple and work less job but it's not like that in my little experience at M.I.T. Mysore. It has 6000 collections related to Computer Science, Information Science, Electronics & Communication, Mechanical and other general books. Classification scheme is highly essential for systematic arrangements of books, access and as well as locating the books. I am trying to convenience them to purchase the classification scheme but they are worried about economic factor. Management peoples are academicians still lack of library administration knowledge, i can't convenience them. There are many discussion was held between us still i am not succeed , they are suggested me to have the own classification method. I don't know how to let them know, this is pained me a lot.



"Librarianship is not a simple job"

Try it, Feel it!

Librarianship

Professionally I am a Librarian Since from 31-7-2008 at Maharaja Institute of Technology, Mysore. It’s newly established an engineering college still building construction progressive well. After my MLISc suffered a lot to get a job finally I got the job at MIT. First day start the work with book accessioning, at that time there is no Library building at least chair and table. Initially wrote the accession register on ground. From 1-8-07 to 14-1-08 Library is established with 6000 collections, 9 racks (5 self’s, 6*9 feet), 45 chairs, 8 reading tables and 2 tables, 1 Almera and 1 computer for staff. Still bar coding, classification and cataloguing is remaining.




Library Classification

Initially documents are classified as their respective branches of computer science, Information science, etc.. Further classify the documents according to DDC (Dewey decimal classification), class numbers are downloaded form LOC online database. We make this variation for user convenient, some of the books from different branches deals with the same subject for example a book of mechanical subject have the subordinate number of electronics in DDC.

Example;

1] Mecanical

Title: Basic and applied thermodynamics Class No.: 621.402

2] Electronics

Title: Engineering electromagnetics Class No.: 621.3

Main class number of both mechanical and electronics are same, if arranged the documents respective their class numbers both branch students easily can’t retrieve the documents cause of this we comes for this decision.

Cricket

Today cricket controversy between India and Australia made world sports news; this is black mark for Australians and Ampires of the 2nd test match. As a game players are should take both defeat and tribute equally, game for entertainment not for other purposes
. I am loveable to Australians game know I hate their behavior
Ampiring is responsible, believable work, world looks them for their decision but what Ampires have made is shameful.

Anil Kumble is really a good captain he lead the team India at that time as a good captain. Winning the match is not important, how to win? That’s the main thing regarding this team India is the real champion.

Work

Work is worship. Really what a sentence? When we love, truthful to our work, it will brings you the respect, satisfaction and many more things that will helps to lead a good life.

Words

Hail stone...>Which is fall down from the sky with the rain
Empathy...>Feeling of power
Far...>A long distance
Fortune...>Chance, Luck, Prosperity, Wealth.

New Year Resolution

• 

  Every year comes with the spirit and new resolutions but it ends without 100 percent completion.2008 is the first year I am going to resoling

2008 Resolutions

Believe God & be honest
Talk less, work hard [Hard work is key to success]
Every day posting blogs
Interacting with LIS-Forum and book marking
Every day learn one new world
At least read any one book completely in this year 2008.

Online Library

An online library now that allows readers to borrow books online and have them delivered to your doorstep within a matter of 24 hours. With a one time registration fee of Rs 499 and a refundable deposit of Rs 499, you can choose a billing plan that allows you to choose books depending on your pace of reading. Charges range from Rs 139/month (for those who want to read three books a month) to Rs 3,000/month (which allows you to borrow 12 books). You can see that library through this URL http://www.librarywala.com/web/Index.aspx

Hiten Turakhia, one of the founders of this library, says he and five other friends were inspired by their college days struggle to get books. Everybody would chip in Rs100 to get reading material for their courses. Sitting at a coffee shop lat year decided to make it easier for today’s generation. Thus librarywala.com was born.

The library six founder members have expertise in related fields like IT, marketing and management. Their market-savvy has clearly paid off, in over two months since its launch.

The website, which is currently operational only in Mumbai with 8,000 titles, hopes to extend its operations to Bangalore and Pune by next year.

As professionals we should think that behind of their inspiration because they are not LIS professionals still they are providing a kind of information service without knowing of fundamental knowledge of regarding fields. As we know we can do such things to improve the library services in an innovative way.

Life

Feel

When we have going to do a any work that time we should be having feeling that work is ours then we will be success in that work

NAAC

Today NAAC commitee visited our department, that's why our department and library looking nice.

TREC project

Introduction
Trec stand for Text Retrieval Conferences. It is retrieval evaluation experiments.Lancaster mentions that probably the first evaluation study in information retrieval was conducted in1953. More recent evaluation studies have been discussed in the annual review of information science and technology some of the recent retrieval evaluation experiments known as Trec experiment
Text Retrieval Conferences
Researchers in information retrieval have concatenate their research on small collection each of the order of thousand of document .The major problem for the researchers was get a text collection large enough to match the real life situation with an infrastructure adequate for conducting with an conducting test on them .In 1991 in order to order t alleviate the difficulty the US Defiance Advanced Research Projects Agency (DARPA) decided to found the TREC the experiment. National Institution Science and Technology (NIST), in order to Annabel information retrieval research to scale up from small collections of data to large experiments.
Smitten and harman- mention that the goals for the TREE experiment have been to :
1) Increase research in information retrieval on large scale test collections
2) Increase communications among academia, industry and government through on open forum
3) Increase technology transfer between research and products
4) Provide a state of the art showcase of retrieval methods of TREC sponsors
5) Improve evaluation techniques
Over a million documents have been used in TREC I, draw mainly from newspapers, newswires and selected journals. The documents range in size: while most of them range between 300-400 terms, some of them several hundred pages. All documents are uniformly formatted into Standard Generalized Markup Language and distributed CD-ROMs.
TREC has sets of activities
the main activity (core in TREC jargon)
subsidiary activities(tracks in TREC jargon)
the core has two types of tasks
Ad-hoc (that corresponds to retrospective retrieval)
Routing (that corresponds to the selective dissemination of information)
Relevance judgement for the old collections and old topic selection are made available in each subsequent TREC series experiment. The routing task involves using some of the old topics on the new collections: the relevance information from the old collection may be use to help formulate the query or the profile.
Out put list from each participating research team are sent to the NIST. Where they are merged for evaluation for each topic the hundred top ranking documents from all the participating teams are merged into a signal set which is then given to the assessor for relevance evaluation. This method called pooling.
First TREC was stated at 1992. From 1992-2005 it held 14th conferences in November month each and every year except TREC- 2. These conferences are co sponsored by DARPA&NIST.

The 15th TREC conference will started in the month of November in this year
Benefits of TREC
Boolean retrieval
passage or paragraph retrieval
combining the results of more than one search
retrieval based on prior relevance assessment
query expansion & query reduction
String & concept based searching.
Dictionary based stemming. And so on.

4) Provide a state of the art showcase of retrieval methods of TREC sponsors
5) Improve evaluation techniques

Over a million documents have been used in TREC I, draw mainly from newspapers, newswires and selected journals. The documents range in size: while most of them range between 300-400 terms, some of them several hundred pages. All documents are uniformly formatted into Standard Generalized Markup Language and distributed CD-ROMs.

TREC as two sets of activites

the main activity (core in TREC jargon)
subsidiary activities(tracks in TREC jargon)

the core has two types of tasks

Ad-hoc (that corresponds to retrospective retrieval)
Routing (that corresponds to the selective dissemination of information)

Relevance judgement for the old collections and old topic selection are made available in each subsequent TREC series experiment. The routing task involves using some of the old topics on the new collections: the relevance information from the old collection may be use to help formulate the query or the profile.
Out put list from each participating research team are sent to the NIST. Where they are merged for evaluation for each topic the hundred top ranking documents from all the participating teams are merged into a signal set which is then given to the assessor for relevance evaluation. This method called pooling.
First TREC was stated at 1992. From 1992-2005 it held 14th conferences in November month each and every year except TREC- 2. These conferences are co sponsored by DARPA&NIST.The 15th TREC conference will started in the month of November in this year

Benefits of TREC
Boolean retrieval
passage or paragraph retrieval
combining the results of more than one search
retrieval based on prior relevance assessment
query expansion & query reduction
String & concept based searching.
Dictionary based stemming. And so on.

Is internet an information retrieval system? Internet is a kind of IRS [Information Retrieval System] it means the system should have information and it give the essential information for it's user{information need}. Internet has lot of information, websites are having that information's the library documents are having the information. An internet has lot of information and that would be indexed, because every IRS that should be indexed internet is also has be a kind of index but it will not appears on screen. An internet has some retrieve techniques. To day most of people aware of an internet because internet is a one of the popular. Users express their information need through the query an internet, it is key word search. Expressing way is important because retrying information depending upon query then system compares the query and indexed objects (database document) after the system retrieve the relevant information. Most of people fall in internet because it possible to retrieve the quick and latest information Internet-components 1. the documents (websites) 2. the index 3. the users (information need) 4. the query 5. search 6. comparison 7. database website Information retrieval system should have documents, index information need and its _expression and retrieve the relevant information than that would be called an IRS. So by all these aspects we can say internet is an information retrival system For example take a google ,if we want the information about" birds" then we will express our information need through the query because internet is a key word search .So we can type the word "birds" after internet search the birds and compare exist websites and internet display the number of available websites but it retrieve the starting 1000 websites only. So we can say an internet is an information retrieval system.
