BoB and TRILT for Research
The document discusses the use of 'bob' and 'trilt' as tools for analyzing broadcast media, emphasizing their roles in research projects related to popular media and science communication. It outlines parameters for selecting content, comparing different metadata between the two tools, and provides a case study on cancer genomics in UK media. The aim is to refine search methodologies while accounting for potential biases and duplicates in the dataset.

Editor's Notes
- #3 Boundaried collection = a relatively constrained and consistent collection of material within a defined archive, as opposed to the results of a general web search, or indeed a search of, for example, the IMDb.com database, where a diverse range of sources will be identified, only some of which can actually be accessed
- #9 As suggested in the guide, I decided to use both BoB and TRILT for various reasons – more in next slides
- #10 Chris mentions parameters earlier on – these are the ones I’ve used as an example. Date range reflects release of seminal paper on the topic, rich science programming in both TV and radio, used Boolean operators as I needed programmes with content on both cancer AND genomics.
- #11 A significant difference is that they search for programmes using different information – BoB searches transcripts, which biases it against radio programmes, whereas TRILT uses metadata such as programme title and synopsis, hence why it’s appropriate to use both tools if you are wanting to study both television and radio programming. In the case of my project, science programming is rich in both TV and radio, so wanted to make sure all representations included. If you do want to stick to one type of media, however, there is an option to search for ‘TV only’ etc Exporting results – guide goes into this in more detail, but essentially is a case of a slightly more automated vs a manual method. In TRILT, I had a relatively small number of results that could be exported into an Excel-ready file. As mentioned in the guide, if you have more results, you may have to adopt a slightly more manual method. With BoB, I manually copied the programme information I required into the spreadsheet – looking into possibility of using web scraping/coding to make this process more automated. Rebroadcasts can still appear even if you select ‘show only latest broadcast’ – I’ve found that with Radio 4 programmes, you can get full versions and abridged versions broadcast at a later time, both count towards results. Same with BBC Sign Zone. Boolean operators can be selected in TRILT but have to be typed in BoB
- #12 There are differences in windows vs mac import of csv files into excel, but this is discussed in more detail in the guide – however, the process is relatively similar. After importing results, it’s important to note that the number of results you have is not necessarily a true reflection of the number of unique programmes. Multiple search terms may yield similar results, meaning there can be a lot of duplicates within the collated results. Make use of Excel’s find and replace tool - knowing that each programme has a unique ID – with some exceptions that I’ll mention shortly – you can use Excel’s find and replace tool to identify and then easily remove repeats.
- #13 Again, there are slight differences in what the tool looks like and how it works, but these differences are discussed in more detail in the guide. In essence, the tool helps to highlight repeats of the programme using Programme ID and these repeats can then be removed as you see fit.
- #14 As I mentioned, this isn’t foolproof – abridged and BBC sign zone programmes have different IDs, so would need to be identified by searching for the programme title, for example. I’ve also encountered simultaneous broadcasts of the same programme on different channels – usually BBC News programmes on BBC One and BBC News 24 – these have different IDs.
- #16 Less referring to my own project here and more giving some suggestions as to what you can do once you have a sample.
