Drupal Lover

Most of the people in my group are working in Drupal . .I am only person who is working in vocabulary, mapping , semantic . .. .etc. I was looking drupal site . .they are amazing .. . .Today, I decided to learn drupal from scratch . . It took me 2hours to get the concepts and running the system. After running I became a lover of Drupal technology. After my PhD , I am thinking to give more time for building my ownsite using drupal . There are some interesting features in Drupal

• OpenID : managing the logging information . It makes people life easier .
• taxonomy ..open issue for researcher .. you can creat your vocabularies and sub vocabularies and filter it.
  
• blog..

I am keeping my fingercross for learning more funtionalities and real use of it.

Agrovoc as Linking data

I was thinking for a long time to write something about linking data. Since I am working on Agrovoc thesaurus. How can we use it as linking data format. Before starting something, we need to clearify some questions.

• What is linking data
  
• What is the uses of linking data
  
• How will agrovoc work as linking data.
  

Ecoterm Meeting

It was great experience in Ecoterm workshop on 5th and 6th of october, at Fao, Rome. I got a chance to represent AIMS registry and Mapping projects. Beside this, I talked with several wornderful person. Gail was wonderful lady with vast knowledge. From the workshop, I came to learn that we should take initiatives now for building enviroment terminology for future. It is a big issue of climate change in the earth. We need universal theasurus for earth science ,geo science. I know it is difficult to build or difficult to maintains. We can keep our finger cross.

I did not satisfy about any mapping project. Nobody explained me clearly about their thoughts. Isaac asked me about prefLabel from SKOS. I have not found any ontology matching tool using SKOS files. In our case , we can use it by parsing skos file.


My idea was concept faced based matching, I was not so smart to explain it. But I feel that we can use it for matching purpose. Facet is a distinct feature of concept that contains hidden knowledge of a Concept. I am writing a paper on it now. Hoping that it will be published and people will get know about more thoughts of mine.

Meta data in KOS

I was thinking to write about Knowledge Organization System(KOS). Since I am working on the same area.

To start about KOS: We have to know about meta data: simply data about data
Meta data for KOS:

* Name /title
* Acronym
* Owner/Creator
* Language
* Type
* Format
* Note
* Usage
* E-Mail
* Date()
* Souces
* version ( we should keep version controlling so that we can walk through different version if we need sometime).
* Usage/subject cover/ purpose/rating
* Singnature(some time use for security reason).

Here is more details about KOS registry draft:

If we take example of Thesaurus Registry for KOS: we can defined it in the following way:

* termId
* termName
* term Qualifier
* term Langauge
* term Created Date
* term Modified Date
* term Modified by
* Souce DB

Every group is having own KOS and their presentation system. This structure/standard totally depends on how and what purpose will you use this system.

It has a lot of blessings in vocabulary system or faceted system
But ,It can not currently be utilised to full petential because semantic structure not explicitly represented.

From my point of view , faceted analysis is big research issue now the days. I do believe that if we can present and adapt our ontology in faceted way, we can browse it easily.

I want to hand off my writing now and thinking lots of digital preservation of digital documents.

Preserving digital Memories

Today, I was talking with my friend Imma , she is library management specialist. I was asking her views regarding digital document preservation. She told me that text document are preserved as pdf and visibility is difficult if the file size is large.

This is a hot issue in the semantic web community, how can we preserve the information. For example , dynamic information is very difficult to preserve( satelight picture or audio information ).

This problem is not only semantic web domain but also it covers all the domain. For example, geographic information , natural pictures, videos etc.

The previously, people took picture by analog camera ;developed the pictures and preserve it in the album. But now, we take lots of pictures with digital camera; how many pictures we preserve it. From my experience, I have lost lot of pictures due to my hard disk crash. I will never get those pictures again. Since, I could not back to the time.

Also, people feel good when they remember childhood memory. But, some people can not remember all the things.

Once I asked one researcher from UK about this. Her vision was an electro magnetic chip that will help to remember things. Do we think , it is enough?

Ancient age, People wrote inforamtion in the stone. Professor Kurodo says"Archiving the mountains of digitalised culture heritage we have amassed for the future is paramount"

There are lots initiative taken now the days:
Recently yahoo announced that they will help digitise 18,000 works of American literature plus material from national and European archieves. That will include books, speeches, audio, video and music.

News channel , BBC also maintains archieve
Ref: http://www.bbc.co.uk/archive/

University of Trento and Trento city lunched new project "LiveMemory". The main theme of the project is to preserve the city information.

The main problem of preservation is format. There is no unique format for a picture , video, audio or text . Another problem is file size. There are some people offering to put your information or files in the online but I think it is not secured.


According to my views, we can do following things:

• Everybody should agree about the unique format. Example W3 for RDF, OWL, XML
  
• We should start the campaign about "Losing Information in Every Second"through the popular search engines.
• Build an International forum for Digital Information(Pictures forum , Document forum etc)
• Make a digital repository for every city.
  

Intially, It will be very expensive but we should not give up. I am sure that we will invent a small chip that will store a large quatity of information.

My master thesis

Recently, I have got compliments from two persons about my master thesis. I was extremely happy to get it.

I had done my master thesis at KTH, Sweden with my friend Ramanjit Singh. He is very nice guy with a good sense of humor. We started our thesis under Prof. Paul Johannesson and Gudrun Jeppesen Neve. Our teachers was extremely nice and helpful to us. Our thesis was about "Evaluation Ontology Construction tools and Ranking techniques". Intially , we had plan to evaluate ontology construction tools at least 10 but we had not time. Specially me, I had got a PhD position at University of Trento, Italy. I told Prof. Paul about it. He inspired me about PhD and told me that you can do 3 tools evaluations. We worked hard and presented our thesis.

I had always fascination about my thesis. But , I was doing completing different things in my PhD studies. After 2 years ,I forgot about my thesis and the previous work .

When I got a letter from one researcher, UK and another e-mail from a semantic columist, USA. I was wornder and feel extremely good. I wish I could do more research on it. Remembering my beautiful days at KTH.

Library Catalog System

A library catalog system keeps records for al bibliographic items .

Bibliographic items:

• books
• computer files
• graphics
• realia,
  
• cartographic

Before librarian keep their records by using library cards. Still, we can find it some places. After coming to www, people are interested to see any information by internet (you can download or access pdf format of book so that you do not need to go library physically)

History:
AS far I know from history, library catalogues are introduced by in the house of wisdom. Then, there was a big collections of books of 7th and 8th centuray in Iraq during Islamic Renaissance. They used totally different catalogue syem in their library.

Later on , Hulagu khan attacked Iraq and distroyed and burnt all books.

Here is some wonderful tools for cataloging
