The Human Semantic Web

My thoughts on the work of Naeve http://kmr.nada.kth.se/wiki/Amb/HomePage and Enoksson on the Human Semantic Web and implementation of Concept Maps.

Enoksson (2006) explains the advantages for extensibility of an open standard language, he used RDF for Conceptual Browsing on the Semantic Web. Enoksson (2006) models things with concept maps that break an overall ontology down into concept sub-ontologies/taxonomies.

Naeve (2005) argue that “combining the human semantics of UML with the machine semantics of RDF enables more efficient and user-friendly forms of human-computer interaction.” Using UML for production of ontologies is as advocated by Baclawski et al. (2001) and Kogut et al. (2002), and Enoksson (2006). Naeve (2005) examines this strong separation between types (classes), and instances (objects) and considers this to be a weakness, which he rectifies for ULM (Unified Language Modeling) developed from UML.

Naeve (2005) gives an example of the need for “semantic mapping” between different words with the same meaning such as ‘author’ in one ontology and ‘creator’ in another ontology in order to establish interoperability and machine readability.

The Table below shows tools, technologies, and languages that can assist in this, and where they are based in a hierarchy from low level information centred interaction to high level user centred interaction (bottom to top), and computing focused to human focused representation (right to left). The Table also shows how each tool fits in with Naeve’s (2005) analysis based on “characteristics of the three different semantic stages” of “Semantic Isolation, Semantic Coexistence, and Semantic Collaboration” :-

Table - Language and Tool Mapping















Naeve (2005) describes Semantic Isolation where databases are available but hidden behind web portals, though the portals advertise their address. Semantic Coexistence is achieved by databases being structured in such a way that it is possible to search them without having to know their location. Naeve gives the example of RDF Schema - RDF(S), this standardises the structuring of the information across RDF(S) databases. RDF(S) provides standardised elements for the description of ontologies, so assisting to enable Semantic mapping. Semantic mapping enables Semantic Coexistence due to Semantic mapping enabling agreement on terms. For the table above the argument presented is that high level user centred interaction (bottom to top), and computing focused to human focused representation (right to left), enable Semantic Coexistence. The tools in the top left are built from those below and to the right of them so the Semantic Coexistence is built from Berners Lee’s (2000) Layered Architecture. Naeve (2005) argues the need for semantics that are understandable to humans as well as machines. That is an important objective of the research outlined in my thesis as without semantics that are understandable to humans, it is not possible for non programmer domain experts to undertake collaborative modelling. Naeve (2005) discusses a bottom up approach where there is a set process of deciding what can be agreed on, what cannot, and on documenting both.

Naeve (2005) argues that where knowledge is tacit it is vital to keep track of the individuals or groups who have this tacit knowledge, and that also the ‘Human Semantic Web’ can help elevate tacit knowledge to explicit.

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.

What's up doc? Join the blog for postgraduate researchers - My case for an invite

This relates to my previous post of April 7th about the research blogging event in Birmingham next month. I've posted to their blog and emailed them to make my case for inclusion. This is my post to their 'What's up doc?' blog - Postgraduate Conference for Computing: Applications and Theory (PCCAT 2011). The post itself is about a different event, a computing Conference at Exeter University and the abstract of my paper for that.

What's up doc? Join the blog for postgraduate researchers

Below are details of an interesting event about blogs for and by researchers :-

'What's up doc?' is a new blog which provides a forum for postgraduate researchers to share experience, give information and tips on matters relevant to them in a fun, yet informed way.

It replaces GRADBritain, which has been a popular online magazine written by and for postgraduate researchers studying in the UK.

As part of the launch we will run a free blog training day in Birmingham on 12 May. Apart from learning what makes a good blog post, we will also explore how to increase your online profile. To apply:

* post an example of an article on the 'What's up doc?' blog

* send an email outlining why you want to be involved, what discipline your research is in and what you would do to champion 'What's up doc?' to tennie.videler@vitae.ac.uk before 25 April.

We will select applicants based on this and reimburse reasonable travel expenses. Places are limited.

This is my Abstract for the paper -

"Abstract: This paper is about potential to provide an interactive visual taxonomy management system. It has been and is part of efforts to structure, manage, and enable understanding of complex engineering, business and/or scientific information to enable those involved to collaborate using a systems approach. The aim and objectives are to close the link between requirements gathering and end-user modellers. The main subject will be editing and display of product data structures (already implemented), business process modelling, and discussion of possible application to phylogenic/phylogenetic (biology taxonomy) knowledge. Modelling in all these areas could make possible new insights. This approach could also be used for public understanding work and visualisation, e-science, and information management. The aim is to apply novel end-user programming research to enable the editing, management, and representation of anything tree/taxonomy based by uniting the software taxonomy structure with the taxonomy structure of the domain to be modelled and visualised, and using Semantic Web technologies to link this with overall ontologies then to end-users for visualisation.

The purpose of this work is to ease management of development use, and re-use of software and make this a continuous integrated process.

To achieve the above aim what is necessary is to establish or link to a computing infrastructure for representation of complex, engineering, business, and scientific information. This kind of Computer Science/Software Engineering research allows for bringing together related fields of Semantic Web and ontology/taxonomy management, end-user programming, and visualisation and interaction with complex information. Then management of software development with and for such professionals can be eased and all be involved via the web.

Further, the structure and accessibility of Semantic Web technologies may also assist with broadening this approach to accessibility for people with various disabilities, and also for environmental modelling."

Government IT use must change: Institute for Government

This BBC article summarises the important point that for IT projects it is crucial to roll them out in increments and test each with the users and for the purpose they are designed for. This is essential for IT project success in the public and private sector also.

http://www.bbc.co.uk/news/uk-politics-12616777.

The article begins -

"The government's handling of IT is locked in a 'vicious circle of costs and failures' and moves at a 'glacial' pace, according to a report.

The Institute for Government recommends sweeping changes to the way ministers order new computer systems.

One recommendation is that new IT systems should be built piece by piece and tested by those who use them."

Resources for Programming Languages

Resources for Programming Languages -http://www.guidetocomputertraining.com/library/programming-languages-basics

This resource is very useful containing a history of programming and programming languages with appropriate links to good articles.

Then there is a section on popular programming languages of the modern day, and another section on uses of programming languages, again with useful links.

This is the description of the site :-

"Computer science is no longer a burgeoning field in education -- it is one of the more popular. With steadily growing job markets due to increased reliance on computers and the internet, learning programming languages may one day be a secondary-school requirement like taking Spanish or French.

For those interested in staying ahead of the curve or just pursuing their interests in programming, there are lots of resources out there available for students and teachers alike. Novices need not be lost, especially because the first language is always the hardest -- after that, they come much more easily. For background information on how programming languages have evolved, and how you can use them, check out the links below to some of the top sites around."

Social Media - Interesting BBC articles - Social Media, Future and Egypt Protests

For my 200th blog post I was inspired to write by reading of 2 BBC articles. One is about the role of Social Media in the Tunisian and Egypt Protests.

Internet role in Egypt's protests - http://www.bbc.co.uk/news/world-middle-east-12400319. - 9 February 2011 Last updated at 06:00 - By Anne Alexander - University of Cambridge.

This article discusses the way Social Media acted as an aid to organisation of the protests, and that this worked in conjunction with ways of spreading the word and existing organisations. The Egyptian Governments shutting down of the internet was not successful because these other ways of organising were already established through a mixture of word of mouth and Social Media

The other article is about the future of Social Media, and the other about the future of friends: Who can topple Facebook? - http://www.bbc.co.uk/blogs/thereporters/rorycellanjones/2011/02/the_future_of_friends_-_who_ca.html - Rory Cellan-Jones 08:00 UK time, Wednesday, 9 February 2011.

This article also mentions the radio 4 program on this subject, which is available at - http://www.bbc.co.uk/programmes/b00y8xdv, with links to the previous 2 episodes. The article argues whether Facebooks dominance is likely to continue or whether new competitors will challenge this.

INCOSE - Systems Thinking

This event was a very useful talk and discussion (Bristol, England) about What is Systems Engineering and Systems Thinking, and examining of a booklet (Z Guide) that describes results of an attempt to write down an explanation of this.

The talk was by Patrick Godfrey of University of Bristol. The description and link are here :-

First Day Back At Vassall Centre - Social Media

I'm a volunteer at Vassall Centre and restarting for my first day of working part time whilst finishing my PhD Amendments.

This describes what Vassall Centre does, and our website is - http://www.vassallcentre.org/.

"The Vassall Centre Trust, a charity led by disabled people, is transforming a former military hospital in Bristol to make it fully accessible for people with all forms of impairment, to empower them and enable them to work on equal terms with non-disabled people. The fully accessible David Hiatt Baker Conference Centre is based within the Vassall Centre."

I'm working on web, and database. On my first day back today I'm creating a Yahoo Pipe of Vassall Centre related news. A good test for this will be that my Yahoo Pipe should bring in this Post as searched for by the tag Vassall.

Yahoo Pipes is a drag and drop way of mashing together RSS feeds, this enables searching, filtering and sorting of feeds via linked information source boxes and operators. This is interesting to me because it involved drag and drop programming without code, a key technology for my PhD.

PhD Viva Result

I have passed my PhD Viva subject to the usual obligations to make agreed amendments. These amendments are minor but extensive.

I'm relieved and delighted with this result, and these amendments will feed into my blog.

Feedback that I've got from comments and surveys on the blog and websites has been a massive help to me.

Thank you to my PhD team, Tony Solomonides and Ian Beeson, and everyone else who assisted me.

Open Standard Layered Architecture Tools

This diagram examines my thinking for 2009-10. This reflects the need to build up from layers of simpler generic information representation and tools that are generic. For representation of information this is more high level and more customised, less generic from right to left. For modelling this is more high level and less generic from bottom to top. Greater use of computer to human translation increases the modelling capabilities. Good interoperability improves the ease of translation, and the layering of simpler information formats with more complex and less generic layers built on top.

Thus it is possible to build on layers of generic solutions from bottom right, and get as far as possible towards the top left, building re-usable solutions before at some point building a final layer of a more customised less generic solution.

This approach maximises re-use and improves maintenance.

Open Standard Layered Architecture for computer to human translation

This diagram shows a central infrastructure of an open standards layered architecture. This enables interoperability at the Computer to computer layer. This gives advantages to developers for maintenance and re-use. This infrastructure aids translation from computer and developers upwards, to end users. Visualising the model/program structure translated upward from code to a navigable interactive visualisation enables accessibility, thus assisting with modelling and end user programming. This infrastructure that aids computer to computer interoperability thus also aids human to human collaboration. This all aids ease of use and re-use of models/programs also.

So far this translation has been enabled upwards from computer to human. Future research could involve translation from human to computer and interaction to make this an iterative, interactive life-cycle process.

Abstract and Poster - BBSRC (Biotechnology and Biological Sciences Research Council) AHRC (Arts & Humanities Research Council) Workshop

BBSRC (Biotechnology and Biological Sciences Research Council) AHRC (Arts & Humanities Research Council) Workshop - 16th and 17th November 2010 - Abstract and Poster - Requirements for Phylogenetic Tree Visualisation - A User Driven Approach - Authors: Peter Hale, Tony Solomonides, Ian Beeson, Neil Willey, Karen Bultitude, Darren Reynolds

Abstract: This poster presentation is about potential to provide an interactive visual taxonomy management system. It will be part of our efforts to structure, manage, and enable understanding of complex scientific information to enable scientists to collaborate using a systems approach. The main subject will be editing and display of phylogenic/phylogenetic knowledge, this could make possible new insights. The project will build on the knowledge of the Faculty of Health and Life Sciences (FHLS) in this biological field, the FHLS Science Communication Unit’s excellent public understanding work and the visualisation, e-science, and information management abilities of the Centre for Complex Cooperative Systems (CCCS) The CCCS team will apply novel end-user programming research to enable the editing, management and representation of biological and environmental information including phylogenetic trees.

UWE has established a computing infrastructure for representation of complex scientific information, has in depth experience in applied scientific research, and on public understanding of science outreach. UWE Computer Science research allows for bringing together related fields of Semantic Web and ontology/taxonomy management, end-user programming, and visualisation and interaction with complex information.

Although web based taxonomies already exist, there are still opportunities to improve the visualisation and interactivity capabilities of taxonomy representation. In addition, Semantic Web techniques can enable automated structuring and management of information.

This research in management, structuring, and visualisation of information will enable visualisation of complex e-science problems to assist in enabling understanding of them, and the CCCS centre has many years of experience in gathering and enabling representations of such problems. This will enable the UWE Science Communication Unit to manage a process of making information managed in this project public. The main scientific information will be based on the work of experienced Faculty of Applied Science (FAS) researchers in Biology and Environmental Sciences. These staff have many years of research experience and much research data to make publicly available, such as phylogenetic information. The taxonomy management system will enable the use of such information and a methodology for its representation and contextualisation in varied interactive ways, according to what is most useful for particular people and types of information. This could be applied to the field of phylogenetic systematic in order to combine biological and environmental approaches and solutions.

UWE has used this technology and approach to visualise engineering product data structures and processes, but there is no reason why this strategy could not be applied to visualisation of phylogenetic taxonomy structures and to the debate on how to classify life forms which is an ontology matter. The use of visualisation via end-user HCI advances and the Semantic Web can widen this debate.

Research intelligence - Damming the 'data deluge'

This is an article in the Times Higher Education about an interesting workshop that I'll be attending -

Research intelligence - Damming the 'data deluge'
7 October 2010

By Neha Popat

http://www.timeshighereducation.co.uk/story.asp?sectioncode=26&storycode=413722&c=2

"A workshop aims to bring design to bear on increasingly complex scientific information. Neha Popat reports

Rapid advances in the technology and methods used in research have undoubtedly yielded great benefits for scientists and society at large.

But the new techniques have also resulted in a surge in both the volume and complexity of the information researchers are expected to analyse.

The challenges of coping with this "data deluge" have been recognised by the UK's Biotechnology and Biological Sciences Research Council and the Arts and Humanities Research Council. They are working in tandem to address the lack of "visualisation" techniques available to present biological data in a user-friendly way.

David McAllister, the strategy and policy manager at the BBSRC, said visualisation was not just about how information is presented on web pages or other electronic media.

"Rather, it is about how researchers can handle and present their data in ways in which new and better analyses can take place. For example, spreadsheets are a good way to store large amounts of numerical data, but are less good as tools for spotting a particular pattern or trend," he said.

To examine the problem, a workshop to be held jointly by the two research councils next month, titled The Challenges of Visualising Biological Data, will bring biologists together with researchers in other disciplines to discuss the difficulties they face and provide insights into how large and complex datasets can be 'fully exploited'."

I'm looking forward to it and designing a poster for it. It's 16th and 17th November invitation only due to numbers, but I hope to link to whatever is put online.

BBC News - Who'd Be a Web Scientist? - 29 September 2010

This is a very an interesting BBC article about a Semantic Web conference :-

"Bill Thompson thinks you can treat the web as an object of scientific study.

I've spent two days this week at the Royal Society in London sitting in the front row of their Web Science conference as one of the nominated 'Twitter chairs'.

It may not sound much, but along with Jamillah Knowles from Radio 5 Live's Outriders and Les Carr from the University of Southampton, I had the interesting task of attempting to manage the conversation about the conference taking place on the Twitter social network.

All the while, speakers as distinguished as Sir Tim Berners-Lee, Dame Wendy Hall and professors Nigel Shadbolt, Jonathan Zittrain and Manuel Castells speak on stage."

Ways of providing openness in a web age

What interests me is the implications of this report on the need for and ways of providing research information. A change is necessary in order to find ways to involve and inform people in an age of blogs, Wikis, and Web 2.0/3.0 and Semantic Web.

Further it is important then to be able to visualise complex data and uncertainty in combination with text, so that it is understandable and conveys the true meaning. This is a problem that in itself needs research.
