Help Documentation

Help documentation tool

For some recent work, I was looking for a help documentation tool and was drawn to this  tool called Dr Explain by this helpful & detailed review. It is an excellent tool that generates slick looking help files with:
- on-line help in the form of a high-quality, coordinated set of HTML pages, which can be hosted on a website, complete with table of context, index, and full text search capabilities built in. There is also option of generating PDF and RTF files:
-a PDF file containing all of the HTML help content in sequence, with both bookmarks (tree-structure like a table of contents in a window usually on the left side of a displayed PDF document), and a table of contents with links to the specified pages, and
-an RTF file, with a structure much the same as the PDF output, providing the ability to use it directly or import it into other tools for further processing.

Lesson Learned : Always use "_" for Ontology Concepts

While Defining ontological concepts - I am finding out building an app it is always better to use "_" pattern. For example, "Anatomical_Structure" instead of often  used "AnatomicalStructure". It is so much convenient for Text Mining Systems and for building interfaces.

Sentiment Analysis on Social Media

This is an interesting article on the topic. Here is one of the quotes that I think is blunt but spot on.

"assuming that you manage to get cleaner data from twitter..


then you have to figure out what people actually are saying “in whatever language it is they’re writing in. 


"We’ve put years and years of work to understand grammar, capitalization, and crap like that, and there ain’t none.”

Ontology 101 using Protege

As part of my work, I have created a basic tutorial on using Protege for creating an ontology that I am happy to share here. 

Linked Data Cloud for the Local Goverments

I was listening to the latest episode in the row between my home council (http://www.nottinghamcity.gov.uk/index.aspx?articleid=1) and the Communities Secretary Eric Pickles(http://en.wikipedia.org/wiki/Eric_Pickles) where Eric Pickles called the council Deputy whose name is Graham Chapman (remember Monty Python ?) "very naugthy boy".  The reason for such comments from Mr Pickles is because the Communities Secretary has urged all councils to publish the expenditure details as part of a "government revolution in transparency", although they will not be forced to do so by law. Nottingham City Council is I think one of the very few who hasn't obliged. Here is what Mr Chapman has to say: "It costs virtually nothing - a couple of thousand pounds - to put it online. It costs another couple of thousand pounds to keep it going online. It's likely to cost about £100,000 to service it.


The jokes and politics (or politics as joke!!) aside, here is a great chance for local governments to take part in the Open Government Data movement and specifically expose the data using Linked Data Cloud way. It might have similar costs to put in online but the service costs can be significantly reduced and can allow the developers in the wild to generate interesting statistics and applications out of it.
