David Haynes will talk about ways in which metadata’s role in the digital economy is changing. In his book Metadata for information management and Retrieval he talks about the six purposes of metadata. Some areas such as information retrieval are due a re-think and other areas such as information governance are becoming more critical.
David is Secretary of ISKO and former chair of ISKO UK. He teaches and does research in the Creative and Social Informatics group at Edinburgh Napier University in Scotland.

KNOWLEGE ORGANIZATION AND INDIGENOUS KNOWLEDGE
Indigenous metadata: the view from a Pākehā (non-Māori person)
By Judi Vernau
Moving between two worlds: translating a classification system
By Edgardo Civallero
IR Models: from theory to practice
by Andrew MacFarlane
This lecture will provide an overview of Boolean and Ranking models and current developments in the field.
Knowledge Organization Education series "Exploring Information Retrieval" is organized in collaboration with the Information Retrieval specialists group, BCS.
The role of AI in search application
by Martin White
The lecture explores the potential value of AI in enhancing search performance, the challenges of defining and managing AI applications and a discussion about the importance of Explainable AI.
Evaluating search performance
by Ingo Frommholz
This lecture will provide an introduction to IR evaluation including the Cranfield Paradigm and typical evaluation measures such as Recall, Precision, Normalized Discounted Cumulative Gain (NDCG) metric, and P@X.
The simple truth is that if you can't find it, you won't buy it - but in that case why do so many e-commerce websites fail at the basics of search, with irrelevant or even zero results for the simplest of queries? Charlie will show examples of search failures and introduce Chorus, an open source reference implementation for powerful and relevant search that can be swiftly tuned to fix common e-commerce search issues.
Charlie Hull is a Managing Consultant and the UK Director of OpenSource Connections (OSC), a specialist consultancy focused on open source search. OSC's mission is to empower search teams with a mix of advocacy, community building, open source software, training and consultancy. OSC hosts the Haystack conference series and has helped organisations including the US Patent Office, LexisNexis, Under Armour and Pond5 build strong search teams and innovative and powerful search platforms. Before joining OSC, Charlie co-founded and ran search specialists Flax for 17 years with clients including NHS Wales, Reed Recruitment and Gov.uk. He is the co-author of Searching the Enterprise from NOW! Publications and a founding member of The Search Network, a regular conference speaker and commentator.

Using Google's family of databases
by Karen Blakeman
This lecture will discuss scope, value and challenges of the range of search applications offered by Google.
User-centred design of search applications
by Tony Russell-Rose
This lecture will cover the principles and practices of user-centred design, key dimensions of the search experience and user experience (UX) design patterns and resources.
Paths to discovery: metadata and findability
by Judi Vernau
We want to help our users to find the information they need, but what do we know about how they might look for that content? What kinds of semantic tools could be provided to support their routes to discovery? This lecture will discuss metadata as a tool in improving IR.
Is search better with metadata? A real life experience
by Marjorie Hlava
This lecture will explore practical issues, using examples of searching, the uses of controlled vocabularies and metadata filters in creating a better search experience from the point of view of an implementor of such systems.
Information seeking behaviour
by Ian Ruthven
In this lecture I shall provide an introduction to the general area of Information Seeking Behaviour, outlining where this area sits within the broad field of Information Science, how it relates to other aspects of Information Behaviour, describe some of the main approaches to investigating Information Seeking and how it can support the design of new systems and processes to help people access information more successfully.
Linked Data and information discovery: from data infrastructure to practical applications
by Eero Hyvönen
The vision of the Semantic Wed is to build the global Web of Data (Giant Global Graph, GGG) for machines to use: based on this an interoperable and intelligent transnational WWW for humans can be created cost-efficiently. This lecture addresses this vision on a cross-domain national level, as in practice the data available are often related to each other within national contexts and application domains, and are represented using national languages, metadata models, vocabularies, and local conventions. The lecture introduces first the fundamental ideas of linked data and Semantic Web and presents then lessons learned in Finland on developing and deploying a cross-domain national ontology and Linked (Open) Data (LOD) infrastructure. To test and demonstrate the infrastructure, a series of 16 semantic portals and LOD services in use have been created using a model that has evolved gradually in 2002--2021. They cover a wide range of application domains and have attracted millions of users in total suggesting feasibility of the proposed model. This work shows a shift of focus in research on semantic portals from data aggregation and search/exploration systems to systems supporting research with data analytic tools, and finally to automatic knowledge discovery and Artificial Intelligence..
