Semantic Web Development

Semantic Web Modelling Centre of Excellence

Introduction

Semantic Web Development and dealing with complexity is a tricky issue. Representing information is a problem where complexity can preclude any single approach. In order to find our way around large quantities of information it needs to be structured. But the information already exists and is still being created, so this makes it a moving target.

I’m sure such matters will be covered at the www2006 conference at Edinburgh .

The structuring of ontologies from the top down can be useful, but can only be achieved where the ontology developers have some control over the information. Much of web development and other creation of information is bottom up, in that there is no controlling authority. This is good for inclusiveness and speed of development, and something that encourages community, and encourages individuals to create their own content, which is a good thing. In his interview with the British Computer Society Tim Berners-Lee http://dig.csail.mit.edu/breadcrumbs/blog/4 answers a question on ontologies. He talks of a top level ontology that can be created to hold certain terms and the need to find out who is using these terms, so that other web pages and databases can be categorised. This would be achieved using URIs (Universal Resource Identifier) and RDF (Resource Description Framework). In answer to what Tim Berners-Lee hopes to achieve, he talks of this bottom up development that is going on, using blogs, and wikis etc and a possible approach of ‘web science’ – ‘the science and engineering of web based things that have a bottom up Web-like structure’.

I think this approach is highly relevant to my PhD research on user-driven programming, with University of the West of England (UWE – Bristol). Not everyone has the time to learn programming especially if their main expertise is elsewhere. They then have to ask others to do the development for them and this leads to delays and mis-understandings. The approach advocated here could enable visual creation of software by members of a community. Members of this community would not need advanced programming skills if other members with more advanced development skills could create a suitable interface for the creation of software. This could be achieved in a similar way to that used in visual web page creation tools, or word processor and spreadsheet software. Also the members who do possess advanced skills could provide ways of sorting, searching and navigating the programs created using the visual development tools. Members could work with either or both groups, according to their skills and interests.

A good first step would be to link communities and sites that have a mix of those with advanced software skills who want to encourage and enable others to learn to program, and of new starters who want to learn. This could involve those who are willing to try out new techniques to make it easier for new starters to train learn and gain experience.

 

Better Ecommerce Web Development For Better Online Business

The latest survey that has been conducted shows that most of business happening in these recession riddled times is most of the times happening online. What it means is that people are not completely engrossed in the idea of starting and running an online business, which is basically because of insufficient funds. As people don’t have enough money to start a brick and motor store, they go for online stores where they don’t have to spend a lot of money.

You too want that share of the pie and wonder what you could do to help customers generate more sales for you. You don’t want your customers to change their mind when they have laden their shopping carts but it’s time for them to reach out for the finalization of the deal. You will always be able to get the best if your website is designed in the right way.

Beneath are the ecommerce web development tips and tricks that can turn a potential customer into a loyal customer for your ecommerce website.

* We all love paths that are organized and sequential and so do our customers. A seasoned ecommerce web designer will help you define the path that the customer needs to take to get to the check out. If we were to draw an analogy then it will be like a story board.

* Ensure that all the prominent buttons need not be searched for but are right out there sticking their necks out. The easier and delightful the process more is the customer going to be in a mind frame to buy it.

* Simplify the entire process. The less cumbersome it is and the sooner your customer gets to the right product the better it will be for your bank balance

* The more number of windows and clicks the customer encounters more are the chances of them losing interest. Remember that a customer can be quite fickle minded due to the huge amount of information and a surfeit of products out there.

* Provide your customers with little indicators that guide them towards the culmination of the deal. All of the things such as the web design, the logo, the products and the words must work in sync to finally leave your customer at the checkout gateway. Place the buy now button at the right hand corner, right size, color and contrast with the background of the website.

* Show your customer the price right away. This ensures that they are assured of transparency and they don’t click to find that out somewhere else. Psychologically that is the very first thing that the customer looks for.

Make sure your website has all these features and you will be amazed to see an increase in the total sales. So, pay attention to these points and run your business in the best way possible.

The IT Industry and Web Development in Bangladesh

The IT industry in Bangladesh has known many ups and downs in the last few years. However, there are certain sectors such as web development and hosting that have registered increased revenue and have contributed greatly to the economy of this country. With the advent of the Internet, it is not surprising that the number of IT companies in Bangladesh, members to the Bangladesh Association of Software and Information Services, has increased from 17 to 326 in 2009. The competence and competitive nature of the IT companies operating in this country have played an important role in the popularity outsourcing to Bangladesh has gained. In Bangladesh, Internet utilization and software export have started to become common only after 1996 and since then, this country has gained a leading position on the Asian market. When it comes to web development and domain hosting in Bangladesh, the focus is on outsourcing and many western countries rely on the services provided by Bangladesh IT experts. As a renowned and preferred outsourcing destination, Bangladesh has gained the attention of various European IT companies and determined major brands open offices in this country. The main reason why specialists and customers alike view the services provided by the people of this country is their cost-effectiveness and their high-quality. When we talk about Bangladesh website design companies or software developers, it is important to mention that the affordability of the services is not relevant for the quality of the work. Bangladesh is renowned for its skillful programmers, designers and developers ranking next to Russia for its high number of IT graduates.

Nowadays, outsourcing has become the success recipe on a highly competitive market. Companies focus more on their core activity and rely on experts to solve secondary issues such as launching their official website. Not only is outsourcing cheaper than hiring specialists and paying for the technology yourself, but you can also take advantage of years of experience a specialized company has in a certain domain to obtain better results. It is therefore not surprising that the outsourcing policy IT companies in Bangladesh adopted have managed to bring high returns and gain them a great reputation on the dedicated market.

The reason why IT services are cheap and efficient in Bangladesh is the fact that this is a developing country. The ambition and perseverance of the population coupled with smaller income rates compared to the western world has determined the IT sector to skyrocket in terms of quality, while maintaining the difference in price making everything from web development to web hosting and design affordable. Whether we talk about design services or software development, you can easily find an expert from Bangladesh capable of solving your problem at a fraction of the cost. This is why the specialists from this country are so sought for, especially by small businesses. In a nutshell, Bangladesh owes its economic increase partly to the IT sector that has brought new opportunities not only to this country, but also to individuals and organizations requiring high quality and affordable hosting, web development or software solution.
