“Why does everybody ask for slides during/after a presentation?”
“Why does everybody ask for slides during/after a presentation? What do you do with them? I’m genuinely curious.” asked @MattMay last night. I use Slideshare for a number of reasons:
- To enable a remote audience to view slides for a presentation they may be watching on a live video stream, on an audio stream or even simply listening to the tweets (and a provide a slide number on the slides to make it easier for people tweeting to identify the slide being used.
- To enable the slides to be viewed in conjunction with a video recording of the presentation.
- To enable my slides to be embedded elsewhere, so that the content can be reused in a blog post or on a web page.
- To enable the content of the slides to be reused, if it is felt to be useful to others. Note that I provide a Creative Commons licence for the text of my slide, try to provide links to screenshots and give the origin of images which I may have obtained from others.
- To enable my slides to be viewed easily on a mobile device.
- To provide a commentable facility for the slides.
- To enable my slides to be related, via tags, to related slideshows.
It seems that I am not alone in wishing to share my slides in this way. Slideshare, the market leader in this area, was recently acquired by LinkedIn. As described in a TechCrunch article published on 3 May 2012: “LinkedIn has just acquired professional content sharing platform SlideShare for $119 million in cash and stock“. The article went on to state that: “SlideShare users have uploaded more than nine million presentations, and according to comScore, in March SlideShare had nearly 29 million unique visitors”.
Slideshare is also widely used in higher education. But how is it being used, especially in the context of annual events for those involved in web management and web development activities?
Use of Slideshare at IWMW Events
A year ago today, on 31 May 2011, in a post entitled Evidence of Slideshare’s Impact I reported on the number of views on slides of talks which had been given at UKOLN’s IWMW event since 2006. hosted on Slideshare. It is timely to update that survey.
The slideshows for each year are available in the following Slideshow event groups: IWMW-2006, IWMW-2007, IWMW2008, IWMW2009 and IWMW2010 (note we changed the naming convention in 2008 once Twitter started to gain in popularity). Note that since not all of the slideshows have been added to the event groups the analysis also made use of the Slideshare tags: IWMW2006,IWMW2007, IWMW2008, IWMW2009, IWMW10 and IWMW11. It should also be noted that on 20 May Slideshare discontinued event groups so we will not be able to use this approach for grouping slides used at IWMW 2012.
The numbers of views for each slide are available on Slideshare. A Google Spreadsheet has been created which summarises the figures. The overall totals are given below.
|Year||Nos. of views

Note that these figures were mostly collected on 25 May 2012, but a small number of changes were made on 30 May. Also note that two different slideshows used in workshop session at IWMW 2012 had the largest numbers of views in May 21011 and 2012.
A paper on “Who are we talking about?: the validity of online metrics for commenting on science [v0]” presented at the Altmetrics11 Tracking scholarly impact on the social Web workshop described how:
… we are not searching in online bibliographic databases for evidence of publications but that we are isolating the existence of online activity on the social web including: blogs; micro-blogging (Twitter); activity on social platforms – LinkedIn, and Mendeley; and sharing of presentations through Slideshare.
The potential importance of Slideshare metrics was also highlighted yesterday in an article entitled Scientists: your number is up published in Nature:
Herbert Van de Sompel at the Research Library of the Los Alamos National Laboratory in New Mexico, who is a long-standing proponent of author identifiers, hopes that the [ORCID] system might be used to generate alternative metrics by linking authors to their outputs in “less traditional venues of scholarly communication, such as tweets, blog posts, presentations on Slideshare and videos on SciTV”.
To illustrate the possible benefits of using Slideshare to host a slideshow consider Kristen Fisher Ratan’s slides on “Metrics: The New Black?“. From this I can view Kristen’s other slideshows and discover that she is the Product Director at PloS (Public Library of Science) and that her Twitter ID is @kristenratan. I can also find related slides hosted on Slideshare with the tags alms, metrics, publishing and altmetrics. This can be useful and I haven’t even looked at the slides yet! Slide 18 (illustrated) states that “Powerpoint download feature inadvertently tracked sub-article usage” which suggests that links to a PowerPoint presentation from a paper might provide usage information about the paper which might be difficult to find in other ways. I’m please that this slideshow has been uploaded to Slideshare!
But if Slideshare have a role to play in a portfolio of online metrics which may help to provide a better understanding of the impact of scientific research, what can be learnt from these metrics taken over a period of six years? Although the IWMW event is aimed at practitioners rather than researchers, it did occur to me that the experiences gained in collating these statistics might be of interest to those who are considering use of Slideshare statistics in an alt.metrics context. Some thoughts that occurred to me:
- Fragmented statistics: A number of speakers uploaded slides to their own Slideshare account. In cases where this was done after the slides had been uploaded to our main IWMW Slideshare account, we did not always know about the alternative location, which could result in difficulties in aggregating the usage statistics.
- Reuse of slides at other events: On a couple of occasions, slides used for presentations at IWMW event were also subsequently used at another event.
However there are clearly more significant things to consider when looking at Slideshare metrics: namely, what is it that is being measured? In this post I will not attempt to answer that question. Instead I will simply conclude by providing a simple answer to Matt May’s question: “Why does everybody ask for slides during/after a presentation? What do you do with them? I’m genuinely curious.” by pointing out what the evidence tells us “They ask for them because they wish to view them. Why, therefore, would you not provide access to the slides?“. Even if the slides don’t provide significant textual content, they may be useful by letting others see how you have designed your slides and structured your ideas.
As I concluded in last year’s post:
Martin Weller made [the] point in his post on The Slideshare Lessons when he said: “by sharing good Slideshare presentations you are sharing ideas, and people will react to these. It can be in the form of comments on your blog post which features the presentation, on the Slideshare site itself, or through other social media such as twitter“. Why, I wonder, are people still hosting their slides in the silo of an institutional Web site when the slides can easily be made available as a social object?
Or to put it another way, why would you not publish your slides on Slideshare?
