Analysing Web searches for public good: inferring the health of populations and individuals.
The UK electronic information Group (UKeiG) is pleased to announce that the 6th Tony Kent Strix Annual Memorial Lecture 2020 is to be delivered by the 2019 Strix award winner Professor Ingemar J. Cox, Department of Computer Science at University College London.
Professor Ingemar J. Cox is Head of UCL’s Media Futures Research Group and a Professor at the Department of Computer Science at the University of Copenhagen. His current research interests include information retrieval and data analytics of online social media, twitter and query logs.
We are also delighted to announce that Martin White will open the event with a presentation entitled Defining the enterprise search experience.
This is a FREE event, open to everyone, but advance bookings are required.

From concepts to Knowledge Organization Systems (KOS)
In this class Leonard Will will review and revise what has been covered in previous classes , with an alternative presentation and a few additional ideas.
Concepts, "units of thought", are the building blocks of all types of knowledge organization system. By creating links to show the relationships which exist between concepts, both inherently and in the context of information carriers such as documents or objects, we can build different types of structured knowledge organization systems to meet the needs of people searching for specific information or reviewing and exploring an area of knowledge.
Information on how to join the virtual class will be emailed to registrants two days prior to the event.
What is a thesaurus? How and why so?
Building on the theory and basic principles set out in earlier sessions of this series, Stella Dextre Clarke will present a practical perspective on thesauri for information retrieval (IR). Guidance in the prime national and international standards, culminating in ISO 25964, provides the underlying frame of reference. After a reminder of the historical context in which the IR thesaurus was originally conceived, the session describes best practice for the basic elements needed in nearly all thesauri: concepts, terms (preferred and non-preferred), and standard relationships. The focus will be on why these and other features are needed. The session concludes with a critical look at the strengths and weaknesses of the thesaurus in today’s context.
How should today’s thesaurus earn its keep?
Since the IR thesaurus was conceived and launched over fifty years ago, the context of its use has changed out of all recognition. In view of its waning popularity, Stella Dextre Clarke will address the question of whether and in what situations the thesaurus still has a role. It will consider how to overcome some challenges for design, development and implementation of a functional, cost-effective thesaurus today.
Why search engines cannot replace knowledge organization?
In this class, Birger Hjørland: will discuss why search engines such as Google do not make knowledge organization (KO) superfluous. Some basic principles behind Google are presented (exact match, best match, web site ranking and search is personalization). None of these principles try to do what KO does: map relations between concepts and conceptual relations as reflected in contemporary knowledge. Prof. Hjørland will further present “the semantic staircase” as a classification of knowledge organization systems (KOS) and argue about concepts as the building blocks of KOS and the Thomas Kuhn's theory as a fruitful way to consider concepts in KO.

Disciplines and phenomena in Knowledge Organization Systems
While word-based KOSs most often list terms for phenomena (e.g. stars, political parties), bibliographic classifications usually list disciplines, so that one phenomenon can be scattered in different classes according to the aspect/perspective under which it is considered.
Claudio Gnoli will present recent projects which are developing phenomenon-based classifications. Phenomena and perspectives are but two of several dimensions of knowledge, also including documents, collections, user needs, people and cognition.

Managing business correspondence in the email era
(and in the MS Teams era)
In this Meet up James Lappin will look at the information management debates provoked by the ever increasing volume and velocity of correspondence. This includes questions such as:
The talk compares rival strategies for organisations wishing to develop a machine learning capability in relation to correspondence such as:
Information foraging in knowledge organisations
The concept of information foraging as a model for seeking and finding information was developed by Peter Pirolli and Stuart Card in 1999. Over the last few years it has re-emerged as a very useful way of describing the way in which employees in organisations seek, and assess the value of, information. Martin White will outline the features of the concept and illustrate their relevance to KOs by applying them to the use made of enterprise search applications.
Critical description and evaluation of classification schemes
We encounter classification schemes in all areas of human endeavor. How do we assess whether a classification is effective, ethical, and useful? Barbara Kwasnik will give an overview, through examples, of some criteria one could apply to evaluating a classification -- any classification. These are:
Assessing a classification’s warrant: What is the origin of the classification? Who designed it and why? What is the conceptual framework or theory that determines the choice of concepts, the rules of division and the relationships? What are the assumptions both hidden and explicit? Is this classification extensible? Can it be repurposed?
How to identify useful qualities (or lack of them) of any classification: Hospitality, expressiveness, and requisite variety; the heuristic capability to stimulate insight and understanding; fertility in stimulating new knowledge; the advantages of a classification being memorable, parsimonious and elegant.
