Two More Similarity by TFIDF Features (GOW++)

We have recently added two more features driven by TFIDF similarity to the GOW++ applications. The first is to provide the 20 most similar people in the person details page. This is based around treating the grants each person is associated with as a single document and calculating the distance between each of these document collections using tfidf.

The second is to list the 5 most similar research areas to the grants page when navigated to from the research areas page. The following example shows that the Optical Devices and Subsystems research area of the ICT theme is also closely related to the Light matter interaction and optical phenomena research area of the Physical Sciences theme and the Sensors and Instrumentation research area of the Engineering theme…


The EPSRC has made a database of all current research grant descriptions available to the ICT Perspectives project. It has also been agreed that monthly updates to this data will be made available in the future.

We are working on adapting our existing apps and perspectives to work with the new data, as well as developing the processing steps such that updates can be processed with as much automation as possible.

There are significant differences between the structure and schema of our previous database and the database supplied by EPSRC. Although this will delay the availability of our apps but these will be supplied as quickly as our limited resources allow.

The new database and apps have been labelled GOW++ and can be viewed by clicking on the menu item on the page header.

Please consider GOW++ features to be at risk of downtime while we work on this.
