Blog for July 2021 Seminar : Ethical Artificial Intelligence

This seminar dealt with the complex issue of ethical artificial intelligence and ontologies. The speaker was Ahren E. Lehnert, a Senior Manager with Synaptica LLC, a provider of ontology, taxonomy and text analytics products for 25 years – http://www.synaptica.com

The central focus of Ahren’s talk was on the relationship between ethics, artificial intelligence and ontologies. Arificial Intelligence (AI) in practice means machine learning leading to content tagging, recommendation engines and terror and crime prevention. It is used in many industries including finance and insurance, job applicants selection, development of autonomous vehicles and artistic creativity. However, we must be careful because there are some outstanding examples of ‘bots behaving badly’. For example, Microsoft’s chatbox, Tay, learned language from interaction with Twitter users. Unfortunately, Twitter ‘trolls’ taught Tay anti-semitic, racist and misogynistic language. Tay was closed down very quickly. Here we are in the territory of ‘ghosts in the machine’ – is that photo really an image of (say) Arnold Schwarzenegger (actor and politician) or is it somebody else who is posing as him or who just happens to look very much like him. More difficult is when you encounter an image of somebody that you know is dead (say) Peter Cushing (actor) whose photo may have been edited into an image that suits a particular project or viewpoint. Are we OK or not OK with these things. It does matter.

Information professionals frequently encounter machine learning – https://en.wikipedia.org/wiki/Machine_learning

Now, however much we may want to go “all in” on machine learning, most companies have not worked out how to “de-silo and clean their data”. Critically, there are five steps to predictive modelling : 1) get data; 2) clean, prepare and manipulate data; 3) train model; 4) test data; 5) improve. We must be sanguine about the results. We will not build a ‘saviour machine’ (!). Machine learning basics include : 1) the need for big data; 2) the need to look for patterns; 3) the need to learn from experience; 4) the need for good examples; 5) the need to take time. We can find good and bad examples of machine learning and we can use the examples of science fiction as portrayed in television and film. For example, ‘Star Trek’ portrays stories depicting humans and aliens serving in Starfleet who have altruistic values and are trying to apply these ideals in difficult situations. Alternatively, ‘Star Wars’ depicts a galaxy containing humans and aliens co-existing with robots. This galaxy is bound together by a mystical power known as ‘The Force’. ‘The Force’ is wielded by two major knightly orders – the Jedi (peacekeepers) and the Sith (aggressors). Conflict is endemic. So bad examples of machine learning (where machine learning fails) arise from insufficient, inaccurate or inconsistent data; finding meaningless patterns; lack of time spent by data scientists on improving machine learning models; the model is a ‘black box’ which users ‘don’t really understand’; unstructured text is difficult.

What is the source of biases which are making their way into machine learning ? Well, people generate context and people have biases to do with : language; ideas; coverage; currency and relevance. Taxonomies are constructed to reflect an organizational viewpoint. They are built from content which can be flawed. The coverage can have topical skews. They can be built by a single taxonomist or a team. The subject matter expertise can be wanting.  Furthermore, Text Analytics is ‘inherently difficult’ : language; techniques; content. Algorithms in machine learning models depend on training data which must be accurate and current with good coverage. Here is a quote from Jean Cocteau – “The course of a river is almost always disapproved of by its source”. Is the answer an ontology ?

What is ethical AI ? What does it mean ? It means being Transparent, Responsible and Accountable. Transparent – Both ML and AI outcomes are explainable.

Responsible – Avoiding the use of biased algorithms or biased data.

Accountable – Taking action ‘to actively curate data, review and test’.

FAST Track Principles – Fairness, Accountability, Sustainability, Transparency.

Whose ethics do we use – the ethics of Captain Kirk from ‘Star Trek’ or the ethics of HAL the computer from ‘2001 A Space Odyssey’. We are back with our earlier ‘Star Trek’ / ‘Star Wars’ conundrum. How will these ethics work out in practice ? How will we reach consensus. How do we define what is ethical and in what context ? Who will write the codes of conduct ? Will it be government ? Will it be business ? Who will enforce the codes of conduct ?

What are the risks given AI in practice ? Poor business outcomes; unintended consequences; mistrust of technology; weaponization of AI technology; political and/or social misinformation; deepfakes; skynet.

Steps towards ethical AI. Steps to success within the organization. Conduct risk assessments; understand social concerns; data sources and data sciences; invest in legal resources; industry and geo-specific regulatory requirements; tap into external technological expertise. There will be goals and challenges to overcome. There should be an ethical AI manifesto or guidelines. An ethical AI manifesto will identify corporate values; align with regulatory requirements; involve the entire organization; communicate the process and the results; nominate a champion. Many existing frameworks of AI Ethics guidelines are vague formulations with no enforcement mechanisms. So,to get started on the AI programme we must clearly define the problem :  what do you want to do ? Why do you want to do it ? What do you expect the outputs to be and what will you do with them ? We must seek to ‘knowledge engineer’ the data to provide a controlled perspective and construct a ‘virtuous content cycle’. We aim for a definitive source for ontologies – authoritative, accurate and objective. Pay particular attention to labelling, quality data and training data. Get the data and create trust in the consuming systems and their resulting analytics and reporting.  Use known metrics. Remember that governance applies to business and technical processes.

July 2021 Seminar : Ethical Artificial Intelligence

Summary

What is ethical, or responsible, artificial intelligence (AI) ? In essence, we can identify three concerns/issues : “the moral behaviour of humans as they design, make, use and treat artificially intelligent systems.” “A concern with the behaviour of machines, in machine ethics” – for example, computational ethics. ” “The issue of a possible singularity due to superintelligent AI” – a fascinating glimpse into the future as computers might ‘take over’. Is this still science fiction ?

 https://en.wikipedia.org/wiki/Ethics_of_artificial_intelligence#Singularity

This seminar encompassed important topics for Knowledge Management and Information Management  practitioners. Topics included ‘bias’ in the machine, in machine learning, in the content cycle, in the taxonomy, in the text analytics, in the algorithms  and, of course, in the real world. Critically, where do knowledge organization systems fit in and how can practitioners play a role in creating ethical artificial intelligence ?  Should companies begin to develop an AI ethics strategy that is publicly available ?

November 2020 Seminar: The framework and ISO standards for Collaboration, KM and Innovation and how these might be integrated into your organisation

Summary

This seminar, affectionately know as the Two Ronnie’s show, aimed to introduce the Five dimensions Framework of Collaboration, Knowledge and Innovation. They gave an overview of the collaboration, knowledge management and innovation published standards ISO44001, ISO 30401, ISO 56002. This was of great interest to the gathered crowd by establishing the relationships there.  They then tackled how it would be valuable to do more to integrate these into a more interdependent, holistic and integrated management system.  They talked about the relevance of systems thinking.  This was followed by some break out sessions where people could have focused discussions on the issues raised.  The meeting finished with a summary from the two Rons.

Pre Event Information

What exactly is an ontology? How can we use them to better understand our information environments? Helen Lippell and Silver Oliver will be explaining all, providing examples from projects they have worked on, and giving you the chance to build your own ontology and domain model. Helen will give an accessible introduction to what ontologies are, how they are being used in a variety of different applications, how they differ from taxonomies, and how you can combine taxonomies and ontologies in models. This introduction assumes no prior knowledge of ontologies or semantic technologies.
Silver will be explaining how ontologies are used in domain modelling, demystifying some of the terminology, and providing case studies to demonstrate ontologies in practice. There will be the chance to get pens and paper out to produce and develop your own ontology and domain model, with additional help from experienced domain modellers Michael and Anya. You will learn the basic ideas around ontologies and domain modelling and see how ontologies can be used to better understand our information environments. You will begin to learn how to develop and use ontologies

January 2018 Seminar: Making true connections in a complex world: new technologies to link facts, concepts and data

Summary

At this meeting new approaches to Linked Data and Graph Technology were presented and discussed. Dion Lindsay introduced the New Graph Technology of Information and David Clarke discussed Building Rich Search and Discovery User Experiences with Linked Open Data.

Speakers

Dion Lindsay
Introducing the New Graph Technology of Information. Graph technology is a rapidly growing method of making complex datasets visually engaging and explorable in new ways, revealing hidden patterns and creating actionable insights. Graph technology is being applied to the vast and unruly sets of unstructured data, with which traditional relational database technology has not been able to come to terms, but which enterprises own and are anxious to exploit.

David Clarke
Building Rich Search and Discovery User Experiences with Linked Open Data This presentation will demonstrate how to leverage Linked Open Data for search and discovery applications. The Linked Open Data cloud is a rapidly growing collection of publicly accessible
resources, which can be adopted and reused to enrich both internal enterprise projects and
public-facing information systems. Linked Open Data resources live in graph databases, formatted as RDF triple stores. Two use-cases will be explored.

Time and Venue

2pm on 25th January 2018, The British Dental Association, 64 Wimpole Street, London W1G 8YS

Pre Event Information

NetIKX offers KM and IM professions a chance to increase our understanding of the new technology approaches that are changing and challenging our work. Our next seminar will give you a chance to confidently discuss and assess the opportunities of new approaches to Linked Data and Graph Technology that can enhance your work and your organisational value.
In everyday language, a ‘graph’ is a visual representation of quantitative data. But in computing and information management, the word can also refer to a data structure in which entities are considered as nodes in a network diagram, with links (relationships) between some of them.
Both the entities and the relationships can also be recorded as having ‘properties’ or ‘attributes’, quantitative and qualitative.

July 2014 Seminar: Selling Taxonomies to Organisations

Summary

The NetIKX seminar for July addressed the need for a taxonomy and its potential to the organization.

There were two case studies presented. The first from Alice Laird, (ICAEW), faced the business case quandary head on. How did they get hard headed Finance to budget for their taxonomy plans? The winning move here was to show in small scale the value of the work. People in the business realised that the library micro-site was the best place to find things and asked why this was so. The knowledge management team were able to demonstrate how the taxonomy could increase organisational efficiency and so helped prove the case to all website users.

The second case study looked at using a taxonomy to help share data between different organizations in the UK Heritage sector. In a talk called ‘Reclassify the Past’, Phil Carlisle (English Heritage) entertained us giving both the successes and the difficulties. Highlighting what could go wrong was a good way to sell a structured taxonomy project. Search, even with a good search engine is more complex than many people realise and poorly organised metadata can cause problems that ‘Google it!’ may not solve. The session ended with a lively set of discussions.

Both case studies provided valuable tips for running a taxonomy project.

Speakers

Alice Laird is the Taxonomy Project Manager at the Institute of Chartered Accountants in England and Wales (ICAEW). Alice leads a team of two taxonomy full-time taxonomy consultants and one external consultant to create the ICAEW taxonomy and implement it on the ICAEW website.
She liaises with stakeholders in the selection and purchase of suitable taxonomy and auto-classification software. She liaises with stakeholders in the creation and implementation of taxonomy and metadata.

Phil Carlisle is a Data Standards Supervisor at English Heritage and has a wealth of experience (both nationally and internationally) in explaining the need for taxonomies and developing them for the historic environment community.

November 2011 Seminar: What next for the web? – a look at linked data and semantic search

Summary

This was a joint event, run with the Information for Energy Group (IFEG) and hosted at The Energy Institute.  The session addressed the issue of linked data and the semantic web.

Whereas Web 1.0 might be thought of as ‘brochure ware’, one-way communication, and Web 2.0 has come to mean interactive, two-way communication online, the future seems to be for information and knowledge management itself to move onto the web.

What is linked data?  Richard gave an excellent introduction to the topic, leading us through a logical path to understanding how information from different data sets can be shared, merged and used online.  When the web originated, it was about publishing text documents with links to other text documents, using html.  Linked data is about linking ‘things’ to other ‘things’, by giving them a label or identifier (a URI).  Things also have attributes, like a name, size, location, etc.

How about semantic search?   Victoria’s talk began from the opposite end of the spectrum – given that linked data exists on the web, how do you search for it?  Traditional online searching is based around keyword search, which uses methods such as counting words, page ranking using links, controlled form searching (eg; OPAC) or metadata.  These methods were developed for searching text.  To search structured data needs a different approach.

Linked data tools and open data publishing seems to have many potential benefits and also some risks; as with any rapid change the regulation and safeguards against the risks will probably lag behind what is taking place in practice.

Speakers

Richard Wallis is a Technology Evangelist and has been with the UK’s leading Linked Data and Semantic Web technology company, Talis, for over eleven years. This coupled with his passion for and engagement with new and emerging technology trends, gives him a unique perspective of the issues challenging Information professionals today. As Technology Evangelist he is at the forefront in promoting, explaining, and applying new and emerging Web and Semantic Web technologies in the wider information domain. Richard is an active blogger and regular podcaster in the ‘Talking with Talis’ series.

Victoria Uren supported Richard.
