Research Student Seminar - Thursday 29 January

On Thursday 29 January, PhD student Lucyantie Mazalan will present a research seminar on The Effect of Dimensionality on the Effectiveness of Nearest Neighbour Searching Methods in Chemoinformatics Applications.

Nearest neighbour search in chemoinformatics application aims to identify the closest molecule to the query molecule. This involves measurements using different molecular similarity coefficients to the highly dimensional molecular descriptors. However, the performance of nearest neighbour search has been found to decrease as the dimensionality increases. One reason is because, as the dimensionality increases, the ratio of the distance from the query point to the nearest and farthest neighbour approaches unity.

This study will investigate a range of different similarity coefficients on different molecular dimensionality. The results of this analysis will be used to assess the effect of the dimensionality on the effectiveness of nearest neighbour searching methods in chemoinformatics applications.

The seminar takes place in the Information School, Regent Court, RC 231.  All are welcome and there is no need to book.

Raspberry Pi Weather Project now live

A project to create a raspberry pi weather station is currently live in the Information School.  The Sheffield Pi weather station has been created by Romilly Close, undergraduate Aerospace Engineering student at the University of Sheffield.  The project was funded by the Sheffield Undergraduate Research Experience (SURE) scheme and is being supervised by Dr Jo Bates, Paula Goodale and Fred Sonnenwald from the Information School. Information about the Sheffield Pi station and how to create your own can be found on the project website .  You can also see live data from the Sheffield Pi station on Plot.ly , and further information can also be found on the Met Office Weather Observations Website .    This work compliments the School’s existing project entitled ‘The Secret Life of a Weather Datum’ which explores socio-cultural influences on weather data.  This project is funded under the AHRC’s Digital Transformations Big Data call.  It aims to pilot a new approach to im

Our Chemoinformatics Group wins Jason Farradane Award

The Information School's Chemoinformatics Research Group has been awarded the 2012 UKeiG Jason Farradane Award , in recognition of its outstanding 40 year contribution to the information field. The prize is awarded to the three current members of the group,  Professor Val Gillet , Dr John Holliday and Professor Peter Willett . The judges recognised the Group's status as one of the world's leading centres of chemoinformatics research, a major contributor to the field of information science, and an exemplar in raising the profile of the information profession. The School has a long association with the Farradane prize. Its second recipient was long time member of staff Professor Mike Lynch in 1980.

Reflections on LILAC 2023

Current student Yuki attended the LILAC Conference - the Information Literacy Conference - in April and shares her thoughts below! I attended LILAC this year as a MA Librarianship student at the Information School. Attending the conference was an incredible opportunity to meet other library professionals from across the world and learn about information literacy from a variety of perspectives.
