Brilliant free online productivity tools: NGram Viewer

Say what you like about Google (and there are certainly many worrying things we could say about them), the internet giants have rapidly done for statistics what John Travolta did for disco dancing in Saturday Night Fever, or what Samuel L. Jackson did for tartan in The 51st State.  Far from being something reserved for the nerdish and the geekish, Google have used statistics to create massively complex algorithms that enable the internet to understand us, and understand the social worlds in which we live.  They have made statistics cool.  They have used statistics as well, to make huge strides in the field of statistical machine translation.  With NGram Viewer, Google have got together with a number of linguistically and statistically brilliant people and come up with a tool which is equally brilliant.

NGram Viewer

I am surprised NGram Viewer is not better-known, because it really is a pretty wonderful thing for any student.  It works very simply: just type a word or phrase into the search box, select your time period and language, then click on 'Search lots of books'.

NGram Viewer then does just that.  It searches through all of the books stored on Google Books (that's more than 20 million), and returns a chart based on the use of that word or phrase over time.

Why might you use it?

I have, for some time, argued that statistics can (and should) provide significant value in any field of study - even my own field of literary and cultural studies.  NGram Viewer can provide good examples of this.  For example, here is a chart in which I searched for the term 'popular culture' in British English:

Here is another chart, in which I searched for the term 'popular culture' in American English:

What does this suggest?  Well, possibly that while the study of popular culture has wained in Britain over the last few years, interest continues to grow in America.

You can search for a range of different terms and project them into the same chart by simply separating each phrase with a comma.  For example, on this chart I have searched for terms relating to three separate models of literary criticism: Structuralism (blue), Formalism (green) and Deconstruction (red) in both British and American English:

What does this tell us?  Well, perhaps it suggests that interest in formalism didn't quite die out with the emergence of structuralism in the 1950s, as some books suggest.  Perhaps it suggests, as well, that deconstruction did not really become a dominant force until the mid 1990s.  Perhaps it suggests, finally, that interest in all forms of critical theory has dropped significantly since the end of the 1990s.

Of course, we do have to be careful with such data if we are using it for study or scholarly activities.  There are some websites which provide excellent guidance for how to use this tool effectively and in a scholarly manner.  It remains a tremendous tool though, even for the merely curious, or for those wanting to generate some formative data on which to develop new ideas.  It is a wonderfully quick way of determining the impact of growing trends, or the influence of emerging (or declining) ideas.

2) Introduction to morphemes

So does language begin with words?

No. Language begins with sounds. It is important to understand this first and foremost. We have already raised this point, but it is worth raising again – language begins with sounds!

If I appear to be emphasizing this with a rather bizarre desperation, it is because it would be easy to think that since we are beginning our exploration of language and linguistics with words that this is where language begins. When you think about it logically though, all words are composed of various sounds grouped together. The word ‘cat’ is composed of three distinct sounds - /c/, /a/ and /t/.

So why aren’t we starting with looking at how sounds create language?

Well, in the not-too-distant past, when European football used to be free on the telly, Manchester United or Arsenal would jet off to Spain for a titanic contest with Barcelona. When the commentators referred to Barcelona, they would pronounce it ‘Bar-se-low-nah’ (bɑ:sɜ:ləʊnæ). After a few years th…

6) Places and Manners of Articulation

Place of Articulation
The place of articulation refers to “the point in the vocal tract where the speech organs restrict the passage of air in some way so pro¬ducing distinctive speech sounds” (Finch, 1999). As with manner of articulation, places of articulation are more frequently used to describe consonants than vowels. The following are the principal terms used in linguistics to describe these:

Bilabial.Sounds formed by both lips coming together” (Finch, 1999).Examples include /b/, /p/ and /m/.

'It's owned by Elsevier': Why this is relevant when choosing referencing software

At my University we are currently discussing how to provide support for software that can help students and staff manage their references and sources.  There are of course many different options available on the market - some free, and some not.  During discussions I have made no secret of my preference for Zotero - which I believe offers the most intuitive and comprehensive functionality.  To this end, I have done some showcases of Zotero for various academics - which appear to illicit one of three responses from them:

Oh, brave new world that has such software in it!  I had no idea - and I want it now!We already use it.  Have been for years.  So why are you telling us about it now?But don't we already have Mendeley in our official software catalogue?

I fully expected the first response - but was surprised at the number of people who came back with the second and third.  It is really rather nice to be able to tell academics who fight tirelessly each year to teach academic referen…
