Jon Udell wrote a post yesterday “Where’s the IFTTT for repetitive manual text transformation?“. In the post Jon describes how he wanted to update some links on one of his web pages and documents the steps needed to do the update to all links in a systematic way. Jon notes:

Now that I’ve written all this down, I’ll admit it looks daunting, and doesn’t really qualify as a “no coding required” solution. It is a kind of coding, to be sure. But this kind of coding doesn’t involve a programming language. Instead you work out how to do things interactively, and then capture and replay those interactions.

and then asks

Are there tools — preferably online tools — that make this kind of text transformation widely available? If not, there’s an opportunity to create one. What IFTTT is doing for manual integration of web services is something that could also be done for manual transformation of text.

While I don’t think it is completely the solution (and agree with Jon there is a gap in the market here) I think OpenRefine (http://openrefine.org) offers some of what Jon is looking for. Generally OpenRefine is designed for manipulating tabular data, but in the example Jon gives at least, the data is line based, and sort of tabular if you squint at it hard.

I think OpenRefine hits several of the things Jon is looking for:

  • it lets you build up complex transformations through small steps
  • it allows you to rewind steps as you want
  • it allows you to export a JSON representation of the steps which you can share with others or re-apply to a future project of similarly structured data.

These strengths were behind choosing OpenRefine as part of the data import process in the http://gokb.org project I’m currently working on where data is coming in different formats from a variety of sources, and domain experts, rather than coders, are the people who are trying to get the data in a standard format before adding to the GOKb database.

So having said in a comment on Jon’s blog that I thought OpenRefine might fit the bill in this case, I thought I’d better give it a go – and it makes a nice little tutorial as well I think…

I started by creating a new project via the ‘Clipboard’ method – this allows you to paste data directly into a text box. In this case the only data I wanted to enter was the URL of Jon’s page (http://jonudell.net/iw/iwArchive.html)

Screen Shot 2014-12-17 at 09.17.52
I then used the option to ‘Add column by fetching URLs’ to grab the HTML of the page in question

Screen Shot 2014-12-17 at 09.21.36

 

I now had the HTML in a single cell. At this point I suspect there are quite a few different routes to getting the desired result – I’ve gone for something that I think breaks down into sensible steps without any single step getting overly complicated.

Firstly I used the ‘split’ command to break the HTML into sections with one ‘link’ per section:

value.split("<p><a href").join("~<p><a href")

All this does is essentially add in the “~” character between each link.

I then used the ‘Split multi-valued cells’ command to break the HTML down into lines in OpenRefine – one line per link:

Screen Shot 2014-12-17 at 09.27.17
The structure of the links is much easier to see now this is not a single block of HTML. Note that the first cell contains all the HTML &gt;head&lt; and the stuff at the top of the page. If we want to recreate the original page again later we are going to have to join this back up again with the HTML that makes up the links so I’m going to preserve this. Equally at this stage the last cell in the table contains the final link AND the end of the HTML:

<p><a href="http://www.bing.com/search?q=site%3Ainfoworld.com+%22jon+udell%22+%22Web services %22">Web services | Analysis | 2002-01-03</a></p>
</blockquote>
</body>
</html>

This is a bit of a pain – there are different ways of solving this, but I went for a simple manual edit to add in a ‘~’ character after the final &gt;/p&gt; tag and then using the ‘split multi-valued cells’ again. This manual step feels a bit messy to me – I’d prefer to have done this in a repeatable way – but it was quick and easy.

Now the links are in their own cells, they are easier to manipulate. I do this in three steps:

  1. First I use a ‘text filter’ on the column looking for cells containing the | character – this avoids applying any transformations to cells that don’t contain the links I need to work with
  2. Secondly I get rid of the HTML markup and find just the text inside the link using: value.parseHtml().select(“a”)[0].innerHtml()
  3. Finally I build the link (to Jon’s specification – see his post) with the longest expression used in this process:
"<p><a href=\"http://www.bing.com/search?q=site%3Ainfoworld.com+%22jon+udell%22+%22"+ value.split("|")[0].trim().escape('url')+"%22\">"+ value + "</a></p>"

Most of this is just adding in template HTML as specified by Jon. The only clever bits are the:

value.split(“|”)[0].trim().escape(‘url’)

This takes advantage of the structure in the text – splitting the text where if finds a | character and using the first bit of text found by this method. It then makes sure there are no leading/trailing spaces (with ‘trim’) and finally uses URL encoding to make sure the resulting URL won’t contain any illegal characters.

Once this is done, the last step is to use the ‘join multi-valued cells’ to put the HTML back into a single HTML page. Then I copied/pasted the HTML and saved it as my updated file.

I suspect Jon might say this still isn’t quite slick enough – and I’d probably agree – but there are some nice aspects including the fact that you could expand this to do several pages at the same time (with a list of URLs at the first step instead of just one URL) and that I end up with JSON I can (with one caveat) use again to apply the same transformation in the future. The caveat is that ‘manual’ edit step – which isn’t repeatable. The JSON is:

Over the last couple of years, the British Library have been running a set of internal courses on digital skills for librarians. As part of this programme I’ve delivered a course called “Working with Data”, and thought it would be good to share the course structure and materials in case they were helpful to others. The course was designed to run in a 6 hour day, including two 15 minute coffee breaks and a one hour lunch break. The focus of the day is very much using OpenRefine to work with data, with a very brief consideration of other tools and their strengths and weaknesses towards the end of the day.

Participants are asked to bring ‘messy data’ from their own work to the day, and one session focusses on looking at this data with the instructor, working out how OpenRefine, or other tools, might be used to work with the data.

The materials for this course are contained in three documents:

  1. A slide deck: “Working with Data using OpenRefine” (pdf)
  2. A handout: “Introduction to OpenRefine handout CC-BY” (pdf)
  3. A sample date file generated from https://github.com/BL-Labs/imagedirectory/blob/master/book_metadata.json (csv)

The slides contain introductory material, introducing OpenRefine, describing what type of tasks it is good for, and introducing various pieces of functionality. At specific points in the slide deck there is an indication that it is time to do ‘hands-on’ which references exercises in the handout.

The schedule for the day is as follows:

Introduction and Aims for the day (15 mins)

This blog post was written during a presentation at the British Library Labs Symposium in November 2014. It is likely full of errors and omissions having been written real-time.

Adam Farquhar, Principal Investigator of the British Library Labs project

In summer 2014 BL ran a survey to improve understanding of digital research behaviour. Around 1600 particpants, 57% femail, 50% academic inc. 32% postgraduates. Nearly 75% were registered readers at the BL. 58% from Arts & Humanities, 21.5% Social Sciences, 13.1% STM. 42.4% from London and a further 35% from other parts of the UK.

92% would recommend the library and 82% said the Library plays an important role in digital research – which was 3 times more than the result for the same question in 2011.

63% of users are satisfied with BL digital services – remote access to more BL electronic resource, the option to view BL digital content on personal devices could improve this.

Some things not changing – perhaps against expectations. Most readers work alone still but using social media more than previously.

1 in 6 respondents were using programming in their research.

Digital collection at BL has been growing rapidly – now around 9million items (huge jump in 2012 from under 2 million to almost 7 million). But remember a book counts as one item – even if many images and pages made available separately, and an ‘item’ in the web archive is a WARC file that can contain many thousands of websites. Looking at size of content in gigabytes the growth is more linear.

The Digital Collections are extremely varied – datasets, images, manuscripts, maps, sounds, newspapers, multimedia, books and text, web archive, journal articles, e-theses, music, playbills.

Lessons from work so far

  • Lesson 1: More is more
    • it’s about digital content – without this you can’t do digital scholarship. Getting the digital content is “bloody hard work”
    • digital deposit coming and will be the basis for the national digital collection in years to come – but not a panacea
    • partnerships – e.g. DC Thomson for further Newspaper digitisation
    • partnership with Google to digitise around 250k works
  • Lesson 2: Less is more
    • Delivering a single ‘perfect’ system won’t be perfect for everyone
    • Deliver people more systems that give more access to more content
  • Lesson 3: Bring your own tools
    • People want to bring their own tools with them – need to enable this to happen
  • Lesson 4: Be creative
    • Let people be creative with the content
  • Lesson 5: Start small – finish big
    • Easy to start with small things – 5 books, 50 books – do this before trying to work with larger collections

Conclusions
* Researchers are embracing digital technology and methods
* Digital collections with unique content are large enought to support research – with some caveats
* Library staff need training to keep pace with change
* Open engagement fits ermeging practice
* Radical re-tooling is needed to support researcher demands…
* … but existing technology provides what we need

Peter Balman, software developer

“Visibility” is a project, funded by money from the ‘IC Tomorrow’ (BL and TSB initiative) v important to institutions like the BL who are releasing data publicly and want to understand the value and impact of doing this

The challenge:
“This challenge is to encourage and establish the necessary feedback to measure the use and impact o f public-domain content”

Looking at the BL release of images under CC0 licence on Flickr. What is the value? what is the ROI?

What can we look at?
* How often is an image used
* What are the demographics of those using the images
* What do people talk about when they use images or refer to images from the collection

Where to start?
BL know anecdotally of re-use, but no knowledge about which images being used, and what proportion of collection being used?
The ‘journey’ of an image in the collection isn’t a linear narrative – it is a tree branching off in different directions.

Approaches:
* Take small section of collection and examine in depth
* Look at all million images and crunch the data

Peter aiming to build an application where you can look at an image, and look at information about how it is being used, mentioned etc., and finally promote images in terms of how they’ve been used.

For each image:
* Search web for the image (e.g. with Tineye, Image Raider)
* Natural language processing on the related page looking for context
* Once you have data what do you do? Organisation of data into categories as per the LATCH theory (time, category, place)

Product ready and starting to crunch data, looking for more institutions to test the tool.

Adam Tovell, Digital Music Curator, British Library & Daniel Wolff, City University

Goal is to develop research methods and s/w infrastructure for exploring and analysing large-scale music collection & provide researchers and users with datasets and computational tool to analyse music audio, scores and metadata.

  • Develop and evaluate music research methods for big data
  • Develop and infrastructure (technical, insitutional, legal) for large-scale music analysis
  • Develop tools for larg-scale computational musicology
  • Use and produce Big Music Data sets

It is possible to use software to analyse aspects of a musical recording. For example looking at:
* Visualisation
* Timings
* Intonation
* Dynamics
* Chord progressions
* Melody

Derived data from s/w analysis can be used to inform research questions.

So far these approaches have been applied to small amounts of music

Field of Music Information Retrieval apply the same techniques to larger bodies of music. These kinds of approaches are behind things like some music recommendation services.

To bring together MIR techniques with musicology academic research approaches need a large body of recorded music – which is where the BL music collection comes in – enabling Large-scale Musicology. BL has over 400 different recording of Chopin’s Nocturne in E-flat major op.9, no.2 – you can ask questions like:
* how has performance changed over time?
* do performers influence each other?
* does place affect performance?
* etc.

BL music collections have over 3 million unique recordings covering a very wide range of genres – popular, traditional, classical, with detailed metadata and a legal framework for making them available to people – sometimes online, and sometimes on-site.

Musicological Questions
* Automatic analysis of scores
* structural analysis from audio
* analysing styles & trends over time
* new similarity metrics (e.g. performance based)
* …

Data sets currently being used:
* British Library – currently curating available music data collections from BL sound archive (currently done around 40k recordings)
* CHARM – 5000 copyright-free recordings + metadata
* ILikeMusic – commercial music library of 1.2M tracks

Analysis results so far:
* ILikeMusic – chord detection
* CHARM – instrumentation analysis
* MIDI-scal transcription
* High-res transcription (create scores from recording)
* BL – key detection, + more

Visualisations – available at http://dml.city.ac.uk

Automatic Tagging – e.g. genre, style, period. To expensive to tag large datasets, automated classification challenging especially without ‘ground truth’.

Dr Beatrice Alex, University of Edinburgh

Looking for mentions of places in Edinburgh using data sources including:
* HathiTrust
* British Library Nineteenth Century Books Collection (main source)
* Project Gutenberg
* Oxford Text Archive data

Interested in using EEBO/ECCO

Workflow:
* Digitised documents from collections above
* Document retrieveal and filtering -> to get ranked lists of Edinburgh specific candidates
* Manual curation – curation of Edinburgh specific literature – need a human in the loop to get the level of detail they desired
* Text minimg – fine-grained location extraction and geo-referencing using the Edinburgh Geoparser
* All data stored in database that then powers the visualisations etc.

Big data IN -> Small data OUT

All input documents must first be:
* Converted to a common format
* Identified as written English text
* Post-corrected automatically if necesssary
* Linguistic pre-processing

  • Document retrieval. The goal is to find all Edinburgh loco-specific items which fit our remit (fiction, autobio, travel)
  • Get ranked dcouments
  • Assisted Curation is done with Palimpsest Annotation Tool (developed at St Andrew’s). Human makes decisions about whether items are ‘in or out’ (e.g. poetry marked as such and then excluded for the moment – may come back to this later)

Gazetteer Creation
* Text minign tools use the Edinburgh Geoparser to mark-up place names and resolve them to coordinates with a choice of gazetteer as the reference source – e.g. Geonames

Not all place matches in the gazetteer are interesting to the project – e.g. ‘Spring’. Clean these out. Have built the gazetteer and now building on this – e.g. want to do further linguistic analysis, building a mobile app so you can explore the literature based on your location

Final outputs will be web-based visualisations and a mobile app – the aim is to create interfaces for both literary scholars and the general public.

Bob Nicholson from Edge Hill.

Victorian’s not associated with humour – “We are not amused”. But jokes were everywhere in Victorian culture – perhaps forgotten or downplayed – you can quote from the great Victorian literature, but what is your favourite Victorian joke?

Jokes reveal lost of things – slang etc. Were an area of existing research for Bob.

Initial Idea:
* Find way of extracting jokes from newspapers
* Start marking up jokes with metadata/semantic tagging
* Try to find suitable image from the BLs image collection
* Overlay text on a suitable image to push out to social media

Issues:
* Where to look?
* Books – e.g. “Book of Humour, Wit and Wisdom” – a joke book. Manually extracted these
* Newspapers – many had weekly joke columns – e.g. 20 jokes per week over many years – thousands of jokes
* Existing markup breaks newspapers down to columns
* But difficult to get access to the source data in appropriate format
* Have manually downloaded and extracted for now
* OCR/Transcription
* Poor OCR not good enough for re-publishing the jokes
* Need to use manual transcription
* Using Omeka to provide transcription platform (using ‘Scripto’)
* Quicker to type up text than markup broken OCR
* Simple xml markup j = joke, t = title, a= attribution
* Want to go further – mark up names, dialogue
* Publishing Jokes
* Original idea of putting speech bubbles on pictures extremely challenging
* Instead putting jokes next to image of person – as if they are telling the joke
* Looking for images that can be used in this way
* Would also like to find images that would work for dialogue style jokes
* Ideally would like to be able to use images which somehow add to the narrative of the joke

What Next?

Coming soon “The Mechanical Comedian” – will tweet a joke each day

http://www.victorianhumour.tumblr.com

@victorianhumour

Eventually will publish database of jokes at http://victorianhumour.com

Will start inviting users to re-interpret jokes – trying to make terrible jokes funny again

All tools used in the project have been free and open source. Allows you to get started cheaply.
Next:
* Seek external funding & new partnerships
* Expand and automate joke extraction
* Implement a new transcription platform
* Develop an accessible online database of jokes

Big picture

Repurposing – difficult to use the digitised versions of newspapers
Remixing – bringing together disparate elements
Gamification – new ways of engaging people with the material
Labs – has allowed Bob to bring an idea and to start experimenting

This blog post was written during a presentation at the British Library Labs Symposium in November 2014. It is likely full of errors and omissions having been written real-time.

Why this tool?

Libraries contain thousands of literary & documentary artefacts up to 4000 years old. How to bring these effectively to a modern audience.

“Images of their own are dull” – browse interfaces tend not to give the user much information. Even at the page image level, it can be difficult to make sense of what you are seeing.

One approach is to put the text on top of an image:
* Correltates words in image/text
* can be searched but…
* only works with OCR
* if text has errors, hard to fix
* text can’t be formattted or annotated

Another approach is to put the text next to the image:
* format text for different devices
* can annotate test for stufy
* easy to verify and edit
* BUT
* must keep image and text in sync
* increases mental effort to find corresponding words in the text/image

If you are going to link text to the image of the text, what level should you do this at?
* ilink at page-level – useful but too coarse. Doesn’t reduce mental effort much
* link at line level
* link at word level

Word level probably most desirable, but how to achiev it?
Manual approach:
* Manually draw shapes around words
* link them to the text by adding markup to the transcription
* BUT
* tedious & expensive
* markup gets complex
* end up needing multiple transcriptions

TILT approach:
* find word in an image without reconginsing their content
* Use an exsiting transcripto f the page content
* Link these two component mostly automatically

Design:

TILT Service
^ ^ ^
Image Text or HTML GeoJSON
^ ^ v
TILT web-based GUI

First you have to prepare image in GUI – identify different parts of the text
Stages:
* Colour to greyscale
* Greyscale to Black and White
* Find lines
* Find word shapes
* link word-shapes to text

Recognising words is a challenge:
* (in most languages) Words are blocks of connected pixels with small gaps between them
* But if there are 300 words on a page are the 299 largest gaps always between words

How to represent word shapes? Simple polygons do the trick

Measure width of words in text, and then tries to match against lengths in transcription – so if the word shapes have not been recognised correctly, the matching algorithm just selects more or less text in the transcription.

Now looking at using of ‘anchor points’ in text that allows the user to identify the start and end of ‘clean’ text in a larger manuscript which might have messy sections that can’t be done automatically. This allows you do what you can automatically, and only deal with the messy bits in a manual way.

Still working on a GUI to work with

Tim Hitchcock (University of Sussex) opening the British Library Labs Symposium

BL Labs a unique project run on a shoestring budget emphasises the role of the library in digital age. “The library creates a space in which the intellectual capital of the library is made available”. Libraries and Museums – not just valued because they are ancient, but because the preserve memories. BL Lab provides a space for experimentation and explores the role of the library in digital research.

Interest in Big Data can obscure the use of Small Data. If we just focus on the very large, and ignore the very small, we miss stuff. A ‘macroscope’ (coined by Piers Anthony!). The idea of a ‘macroscope’ in Digital Humanities come from Katy Borner in her paper on “Plug-and-Play Maxcroscopes”. A visualisation tool that allows data to be viewed both at scale, but also driving down into individual data points in context. Tim see’s this paper as the trigger of interest in the concept in Digital Humanities.

Paper Machines (http://metalab.harvard.edu/2012/07/paper-machines/) – builds on Zotero to allow the user to build their own ‘Google Books’ + ‘Google Earth’. Not problem free, but concept of allowing you to look at the large and small scale. Jo Guldi and David Armitage “The History Manifesto” – they say that ‘micro-history’ is irrelevant. Tim says they only want to look at the largescale – disregarding the other side of the ‘macroscope’.

Scott Weingart – The Historian’s Macroscope : Big Digital History. Blog post “The moral role of DH in a data-driven world”. Weingart advocates ‘network analysis’ and Tim finds him convincing. Weingart makes a powerful case (in Tim’s view) for the use of network analysis and topic mapping as a means through which ‘history can speak to power’ – similar aim to Guldi and Armitage.

Is this an attempt to present humanities as somehow ‘equal’ to STEM? Moving humanities towards social science.

Jerome Dobson “Through the Macroscope: Geography’s View of the World” – using GIS. Again, pulls humanistic enquiry towards social science.

Ben Schmidt ‘prochronisms’ – looking at language use in artistic works purporting to represent historic reality. Looks at the individual words used, then maps against corpuses such as Google Books etc. Althoguh not described as a ‘macroscope’ approach but in Tim’s view perhaps comes the closest to using the full extent of what a macroscope is meant to achieve. Tim highlights how analysis of the scripts for Mad Men shows an arc across the series from (overstated) externalised masculinity of the 1950s, to (overstated) internalised masculinity of the 1970s.

Tim see’s the prochonisms project as interesting because it seems to be one of the few projects in this space that reveals new insights, which many of the big data do not [I feel this is neglecting the point that sometimes the ‘obvious’ needs supporting with evidence]

What are the humanities? Tim see’s the excitement and power of humanities – place detail into a fabric of understanding. Need a close and narrow reading of history to get to the detail of the excluded parts of society – these are not reflected by the massive.

What Tim sees as missing from modern macroscope project is looking at detail, at the individual, at the particular. We risk losing the ability to use fine detail.

Tim recently involved in project to look at trial transcripts from Old Bailey, looking at the language used to represent violence and how that related to trial outcomes and sentences. In STEM ‘cleaning data’ is a chore, they are interested the ‘signal’ that makes its way through the noise. Assumption that ‘big data’ lets you get away with ‘dirty data’.

Humanists read dirty data and are interested in its peculiarities. Tim sees the most urgent need for tools to do close reading of small data. Not a call to ignore the digitial, but a call to remember the tools that allow us to focus on the small.

When we read historical texts, how do we know what the contemporary reader would have known – when words have a new or novel use.

A single message from this talk – we need ‘radical contextualisation’. Every gesture contextualised in knowledge of all gestures ever made. This is not just ‘doing the same thing’. Tim’s favourite fragment of meaning is from linguistics – ‘voice onset timing’ – encompasses the gap between when you open your mouth to speak and the first sound. This changes depending on the type of interaction – by milliseconds. The smallest pause has something to say about the type of interaction that is happening.

Tim would like to see this level of view for the humanities – so we can see in every chisel stroke information about the wood in which it is imprinted, the tool that made the stroke and the person who wielded the tool.

Comments from floor:
* Even in science ‘big data’ not relevant in many cases
* Lingustic scholars have been working on this for years – e.g. Oxford Historical Thesaurus – we need to be wary of re-inventing the wheel
* Textual scholars can learn a huge amount from the kind of close reading that is applied to museum objects
* It is relatively hard to get largescale information about collections
* Online auction catalogues -
