How Ontology and Modelling Tools were chosen for my PhD

The modelling tool Vanguard System was chosen because it handles Units and uncertainty well something that was necessary for the DATUM project with Rolls-Royce as partners (Scanlan et. al, 2006). The same advantage was the case for the PhD because of the need for extensibility such as risk and uncertainty modelling. Other advantages of Vanguard System were ease of installation and use, ease of linking to spreadsheets and databases, facilities for web enabling of models, and the ease with which formulae can be entered and linked with a high level programming language where necessary (similar to spreadsheets but with a tree based user interface). Experimentation with Protégé showed it was possible to translate the Protégé tree into a Vanguard System tree. This fit in well with the stepped translation to be developed. The open standard nature of Protégé made it possible to use this software without being locked in to it. Tools such as TopBraid Composer can provide additional higher level functionality such as an improved user interface and more tools for user interaction and modelling by end-users so is future work.
There was a need for the DATUM project and for the PhD to minimise programming, so Jena was not used, but Leavers' (2008) MSc project used this effectively, and there was regular contact with the developers of ACUITy (Aragones et. al., 2006), to examine how that more software centred approach was used. Given more time that approach could have been used. Metatomix M3t4 was also used effectively as a high level tool to interact with Jena. So results of research with Jena and/or ACUITy and m3t4 would have shown similar results to the approach of using Protégé and Vanguard System.
These types of tools improve with research and development each year so reproducing this research is becoming easier. New ways of modelling at high level with involvement of end-users is thus practical.

Empowering engineers and others to create software

With my PhD work, there was extensive prototyping of software solutions created and feedback from engineers. At first engineers tended to ask for software that followed the strategy of the business and met its deadlines. What emerged over time though was a desire from engineers to have more control over the software so that they could do this themselves and have input into this strategy. With a top down strategy and inflexible software and rules about what can be used and installed, missing of deadlines, and problems in meeting aims were built into the system, and engineers realised this.

So even in engineering, an industry that by its nature has to be conservative, due to safety needs, it is realised that empowerment is necessary in software development. So there was a need to empower the engineers by provision of collaborative software that could be installed and used as easily as possible and be adaptable. Empowering the engineers to be fully involved in the creation and maintenance of such software, because they're interested in the software and what it can do, was essential to make the use, re-use and maintenance of the software practical. This is necessary because it would not be possible to achieve application of useful software by any top down strategy, with limited involvement of higher managers and software suppliers. Visualisation and modelling of the software by a large range of people can be achieved by use of diagrams to show the problem and software structure, as part of the software and how it is used.

Further feedback was obtained from others via an online survey of a greater cross section of others rather than only engineers. This bore out that people want more control and involvement in software development and use, and that visual editing of the software over the web is the best way to achieve this.

More Customisable Software Systems

My experience of dealing with projects that create new software systems is that they are very ambitious, but not very modular or customisable. Under management pressure for meeting of timescales, they are often released too early with insufficient consultation with users. Then software developer's time is reallocated to a help desk, in order to deal with the problems caused by the release of software too early, too unchangeable and with too little user involvement.

A solution is to produce highly customisable software, so that the software team don't have to anticipate every problem the users will want to solve. Then many users with more advanced needs and computing abilities could customise software for their needs.

Modelling Methodology - User Driven Modelling

The User Driven Programming approach advocated in this research has the advantages that it is using a modelling approach for creating modelling solutions and involves creating systems to create systems. This makes it possible to solve the problem by breaking it down into stages and allowing software developers to concentrate on the most complex software problems and domain experts to be able to concentrate on their domain problem. The standardisation possible in this approach can allow software developers to create modelling systems for generic purposes that can be customised and developed by domain experts to model their domain. This methodology can be facilitated by :-

* Modelling Tools - Building an end-user interface and extending the translation capabilities of UML (Unified Modelling Language) and/or other modelling tools (Johnson, 2004).

* Spreadsheets - Improving the structuring and collaboration capabilities of spreadsheets, and enabling customisation of spreadsheet templates for particular domains and users.

*Ontology Tools - Extending the modelling capabilities and equation calculations in ontology tools and providing an end-user interface.
Semantic Web/Web 2.0 - Extending the capabilities of Semantic Web and Web 2.0 style web-based development tools to allow collaborative modelling.

* These possible solutions are not mutually exclusive and their combination could be the best way of providing usable collaborative modelling tools for computer literate end-users and domain experts. The link between these alternative ways of advancing current research is translation and User Driven Modelling/Programming.

This diagram shows the solutions, and how these could make User Driven Modelling/Programming possible :-

Semantic Web Applications

In order to increase the use of Semantic Web technologies it is necessary to create applications that make use of the Semantic Web for practical applications. Enabling Modelling with Semantic Web technologies could encourage domain experts to fill ontologies with useful information, so generating more benefit from their use.

The use of Semantic Web languages as information representation and even as programming languages would assist greatly with interoperability as these modelling languages are standardised for use in a wide range of computer systems.

Research can bring together End-User Programming, Modelling and the Semantic Web approaches, so the shaded area is examined.

An important area of research is a technique for end-user programming, that of allowing visual modelling of information. This corresponds to the type of work normally undertaken using spreadsheets. This research involves using Semantic Web technologies to enable end-user programming. The technology is applicable to any problem that involves user interaction, calculation, and modelling so it can be applied to a wider range of tasks and subject areas.

A methodology that involves structuring of information through Ontology and Semantic Web techniques and enabling end-user programming through visualisation and interaction aims to achieve effective production of generic models. Horrocks (2002) explains Semantic Web technologies and the use of agents and ontologies, and ontology representation languages. This demonstrates the linked nature of Ontology and Semantic Web research.

Berners-Lee and Fischetti (1999) sum up the advantage of a Semantic Web program over programs in other languages. They write, "The advantage of putting the rules in RDF is that in doing so, all the reasoning is exposed, whereas a program is a black box: you don't see what happens inside it." They discuss the use of Semantic Web languages as programming languages and explain the benefits declaring "The Semantic Web, like the Web already, will make many things previously impossible just obvious. Visual Semantic Web programming is one of those obvious things".

Berners-Lee et al. (2006) explain the importance of visualisation for navigation of information "Despite excitement about the Semantic Web, most of the world's data are locked in large data stores and are not published as an open Web of inter-referring resources. As a result, the reuse of information has been limited. Substantial research challenges arise in changing this situation: how to effectively query an unbounded Web of linked information repositories, how to align and map between different data models, and how to visualise and navigate the huge connected graph of information that results." The use of Semantic Web languages as programming languages would assist greatly with interoperability as these languages are standardised for use in a wide range of computer systems

The main advantage of open standard representation of information provided by the Semantic Web is that information can be transferred from one application to another. Additionally it provides a layered architecture that allows for a stepped translation from users to computer and back for conveying results of a modelling run. The program transformation approach argued for by Lieberman (2007) can be used to translate from a domain expert End-User Programmer abstraction to models represented by Semantic Web languages, ontologies and code.

Use of Semantic Web technologies is a means for open standard representation of collaborative models, transformation into different representations as required, and for provision of a high-level interface as a tool for model visualisation and system creation. Structuring of information through Ontology and Semantic Web techniques and enabling End-User Programming through visualisation and interaction can achieve effective production of generic models. Semantic Web technologies could assist greatly with Web based Simulation and Modelling. Kuljis and Paul (2001) evaluate progress in the field of web simulation. They argue the need for web-based simulations to be focussed on solving real-world problems in order to be successful. Miller and Baramidze (2005) establish that for a "simulation study that includes model building, scenario creation, model execution, output analysis and saving/interpreting results. Ontologies can be useful during all of these phases." Model-Driven Programming and the Semantic Web are explained by Frankel et al. (2004).

Research in the use and visualisation of Semantic Web information can provide the tools that end-user programmers have been lacking until recently, and these tools can be used for modelling. Crapo et al. (2002) assert the need for a methodology for creation of systems to enable more collaborative approaches to modelling by domain expert end-users, and that this combined with visualisation would allow engineers to model problems accurately.

Many organisations produce text based reports from their IT systems. But text based reports do not always show information well enough for good decision making. Automated conversion of these reports into Semantic Web languages could assist greatly with this. So a translation process is required and can be implemented as part of an overall User-Driven Modelling/Programming Approach. Once reports are converted to a standardised representation, hierarchical information can be represented as clickable trees and numerical representation as charts. This makes it possible to customise outputs from existing IT systems and so allows an improvement in readability of information without major changes to the way it's produced. This could provide a large gain at little cost.

User Driven Modelling Justification

There are many computer literate people who are experts in a particular domain. Given the opportunity they will develop their own software (Scaffidi, 2005). There is a need in many domains for people to create software such as engineering models, scientific taxonomies, business systems, and in the arts. Examples of software systems that enable creation of models without necessitating code writing are spreadsheets, visual web development systems, and database management systems. Crapo et al (2002) explain the need for a methodology for creation of systems to enable more collaborative approaches to modelling by domain expert end-users that make use of structured and visualised information. Peirce (1904) explained that systems can be represented logically by humans, and this applies to software development and information representation on computers. Thus it could be made possible to represent systems with natural and visual languages. Though Nurminen et al (2003) argue that people prefer usability over automation, it is possible to achieve both by providing a stepped translation capability that ensures users are constantly kept informed of the steps taken. This approach is advocated by (Johnson, 2004). Automated translation from a people-centred view of information to software for computers can aid in software development by domain expert end-users and help ensure they can communicate models directly to computers. Software developers can then concentrate mainly on creating systems that enable domain experts to develop software, rather than developing individual software models on behalf of domain experts, which is difficult and prone to communication problems.

History of End User Programming

1960s

In the 1960s Dartmouth BASIC programming language [7] was designed and implemented at Dartmouth College by John Kemeny and Thomas Kurtz. Over time BASIC became a popular language for home users, and business use, it introduced many people to programming as a hobby or career. Many of the modern concepts of computer graphics, dynamic objects and object oriented programming were prototyped by Ivan Sutherland in 1963 in Sketchpad [13][14]. In the mid 1960s Seymour Papert, a mathematician who had been working with Piaget in Geneva, came to the United States where he co-founded the MIT Artificial Intelligence Laboratory with Marvin Minsky. Papert worked with the team from Bolt, Beranek and Newman, led by Wallace Feurzeig that created the first version of Logo [25] in 1967. In the late sixties Alan Kay [2][3][17] used the term 'personal computer' and created a concept prototype, the FLEX Machine, he also envisaged a 'Dynabook' machine, the sketches for this look very similar to the laptop computers of recent years. The Simula [28] language was developed by Ole-Johan Dahl and Kristen Nygaard and this included Object-Oriented concepts. Douglas Engelbert's worked on a project to augment the human intellect, as part of the Augment [8] project he demonstrate Hypertext and video conferencing.

1970s

Alan Kay joined the Xerox Palo Alto Research Center (PARC) [17][19] California in 1971. Throughout the seventies the group at PARC led by Dr. Kay developed an integrated programming language and programming environment called Smalltalk [10]. In the early seventies the Alto personal computer was created at the PARC. The Alto eventually featured the world's first What-You-See-Is-What-You-Get (WYSIWYG) editor, a commercial mouse for input, a graphical user interface (GUI), and bit-mapped display, and offered menus and icons, and linked to a local area network. The Alto provided the foundation for Xerox's STAR 8010 Information System. There was still a need to find a common use for a personal computer that would increase the demand for it. In 1978, Harvard Business School student, Daniel Bricklin, came up with the idea for an interactive visible calculator. Bricklin and Bob Frankston then co-invented the software program VisiCalc [1]. VisiCalc was a spreadsheet, and the first 'killer' application for personal computers as this application provided a justification for using personal computers as a productive tool.

1980s

During the 1980s ownership of personal computers became increasingly popular and many home users programmed using BASIC. In the early eighties IBM developed the first personal computer built from off the shelf parts (called open architecture) [15]. This included a command line operating system written by Microsoft and the Microsoft BASIC programming language. Apple developed the GUI further for the Lisa [5] that later became the Macintosh (Mac). The IBM style PC became most popular for business applications, while the Apple Mac was often used for Desktop publishing.

1990s

End User Programming research has continued to the present day. Research has continued in techniques of Visual Programming [9] e.g. Alice [4], Programming by Example [2][21], programming with automated assistance [20], and Natural Language Programming [27]. Squeak and Croquet[6] have developed from the early work in Smalltalk.

Tim Berners-Lee [23] developed HyperText Markup Language (HTML), and has been involved with the World Wide Web Consortium (W3C) [29] in developing standards base languages for the Web. This has encouraged the growth of the 'Semantic Web' [11] which allows both humans and computers to search and interact with pages more and so encouraged the development of interactive web pages and communities.

2000s

Recent, present and future research can enable the use of semantic web technologies, (developed from HTML by Tim Berners-Lee [23] and others), to enable End User Programming. This fusion of research and technologies is illustrated by Henry Lieberman's home page [12] which has explanations of both areas of research. Examples of this fusion include Protégé [22], Jena [16], TopBraid Composer [24], and OpenCyc [18]. Information about these technologies is available in my semantic web page - http://www.cems.uwe.ac.uk/amrc/seeds/PeterHale/RDF/RDF.htm. A related development is that of web 2.0. Visual development environments based on AJAX (Asynchronous JavaScript And XML) [26] aim to reproduce on the web, the functionality provided by office tools such as Excel (which is often used as an End User Programming Environment). Information about Ajax and Web 2.0 is available in my Ajax/web2.0 page - http://www.cems.uwe.ac.uk/amrc/seeds/Ajax/ajax.htm.

I am a Researcher in the final year of my PhD. I specialise in applying Semantic Web techniques. My current research is on a technique of 'User Driven Modelling/Programming'. My intention is to enable non-programmers to create software from a user interface that allows them to model a particular problem or scenario. This involves a user entering information visually in the form of a tree diagram. I am attempting to develop ways of automatically translating this information into program code in a variety of computer languages. This is very important and useful for many employees that have insufficient time to learn programming languages. I am looking to research visualisation, and visualisation techniques to create a human computer interface that allows non experts to create software.

End User Modelling Tools

This article examines the need for users to be enabled to program, and the tools that could be created to assist this. It also examines how UML (Unified Modeling Language) tools could be adapted to enable developers to provide an environment for users to program, and how new UML tools could be created to help users to develop software themselves.

User involvement is important in the development of software but a domain expert does not necessarily possess expertise in software development, and a software developer cannot have expertise in every domain to which software might apply. So it is important to make it possible for software to be created, using methods that are as close as possible to that which the domain expert normally uses. The proportion of domain experts in a particular domain (aerospace engineering) for example who can develop their own programs is fairly low, but the proportion that are computer literate in the everyday use of computers is much higher. If this computer literacy is harnessed to allow the domain experts to develop and share models, the productivity for software development will be increased and the proportion of misunderstandings between domain experts and developers reduced. The domain experts can then explore a problem they are trying to solve and produce code to solve it. The role of developers would then become more that of a mentor and enabler rather than someone who has to translate all the ideas of experts into code themselves. Other developers may work at providing better translation software for the experts.

In my research I examined the role of UML (Unified Modeling Language). However there are important gaps in the functionality of UML tools for user centred design. Palanque and Bastide (2003) identify these gaps "For the team of methodologists (Rumbaugh, Jacobson, Booch) that shaped the UML, User Centred Design was not a central concern." These gaps are of even greater importance when attempting to make it possible for people who are not programmers to create software. UML tools could assist software developers in creating a modelling environment suitable for domain experts to use to solve their problems. To achieve this would require a major change in UML tools to enable modelling of user interaction as the core concern. Enabling users themselves to create software using UML type tools would require development of a new type of UML tool specifically designed for ordinary users. This would be compact and simple, but provide enough capabilities to ensure users' designs are robust. This would also fill a gap left by engineering and scientific modelling tools which are powerful but do not have collaboration, communication, and ease of use as central concerns.

Introduction

SEEDS (Systems Engineering Estimation and Decision Support) team - involved in cost modelling solutions.

End User Programming

Why do we need to make it easier for end users to program?

Figure 1 - End User Programming

Based on data from US bureau of Labour Statistics. Sources - http://www.cs.cmu.edu/~bam/papers/EUPchi2006overviewColor.pdf - Myers et al. Scaffidi, C., Shaw, M., Myers, B. (2005).

User Driven Programming

Software development is time consuming and error prone because of the need to learn computer languages.

Mitigating this allows users to devote full effort to the problem to be solved.

User Driven Programming creates software that enables people to program with visual representation of a tree diagram.

Applied to aerospace engineering but should be applicable to any subject.

Figure 2 - Source to Result TreeTranslation

Translation

The Ontology representation is translated into a computer model.

An Ontology defines relationships between things.

Relationships can be conveyed to a software model that evaluates them.

To achieve this the translator requires -

1Search trigger(s) resulting from user actions.

2Knowledge of the relationships between nodes in the tree.

3Ability to read a equations held in a standardised mathematical form.

4Rules of syntax for the language of the code to be output.

Figure 3 - Visualisation and Interaction Mechanism

Semantic Web Modelling system

1. Connections are established between the ontology system and any
databases, spreadsheets, or other systems that hold relevant information for
that modelling problem.


2. The ontology is created using RDF/OWL [2], and an interface built to
allow domain experts to edit the ontology.


3. Libraries are created in a partnership between ourselves and domain
experts.


4. Taxonomies are populated by model builders who want to use them for
their modelling problem. These are based on the libraries created in step 3.


5. Taxonomies are colour coded for ease of understanding, this part of
the diagram was built with Vanguard system (explained below). We have created a
link between the ontology tool and this decision support and calculation tool.
Vanguard system reads information from the ontology tool.


6. There are 2 sorts of constraints that can be used in order to make it
easier for users to build and adapt models. These are constraints on the way
the ontology, and models are built, and user interface constraints to reduce
the scope for error.


7. The colour coding makes calculation clearer because all taxonomies
can be used in any calculation, this results in a multicoloured result tree
that represents the entire calculation history. User choices affect how items
are related for the calculation; choices could be made manually or via a
search. Colour can also be used to represent cost, time, or uncertainty.


8. Each node can also represent uncertainty, and we have prototyped
including uncertainty expressions in the calculations.


9. The result tree can be represented on the web and in other programs,
this allows for further searching, processing and evaluation of results.
Visualisation techniques and the use of searchable languages such as XML, and
SVG can assist in this.


10. and 11. Experts such as designers can interact with the
ontology, the model, and results, it's intended that there will be a two way
feedback mechanism where the expert can make changes at any stage, and this
filter into changed results. This can then support a cycle of results and rework.

Visualisation

Figure 5 shows how the program visualises information for the spar and its' part definition, material, manufacturing processes etc.

Figure 5 - Vanguard Studio Visualisation

• This is an interactive view of the Vanguard Studio model that was read from Protégé.


• Changing the figures and pressing recalc results in a new calculation.


• 
  This tree is translated into SVG (Scalable Vector Graphics) and JavaScript for an interactive CAD view.

Translations from Tree Based View to Component Diagram

Figure 6 shows the spar translated to XML and visualised using Flash multimedia. The spar is then translated and visualised in an SVG based interactive diagram.
