tuals - technologies for user-adaptive learning systems. Our mission
is to identify gaps in the application of cutting edge analytical technology. We aim to create a technologically enabled ecology of information that is scalable, robust and individually tailored, for which we will develop peerless collections of intelligent tuals that will learn and adapt to personal learning styles and will absorb, digest, categorize, visualize and repurpose digital information based on a dynamic model of the user's contextual perspective, as it is automatically derived from observing the user's engagement with the informational environment and from explicit user refinement.

Interesting application to Genomic data: IEEE Article

Does navigating through 'inaccessible' spaces help?

How about navigating through 'non' spaces that are metaphorically 'spatialized' for visual re-presentation?

searching ieee Xplore for 'visualizing text clusters'

| |

Searched ( ((visualiz*)<in>metadata ) <and> ((text*)<in>metadata ) )<and> ((cluster*)<in>metadata )

My search matched 71 of 1692897 documents.

I reviewed the abstracts of the first 17 or so and found a lot of noise around volumetric modeling...Decided to remove texture* from my search...

So I Searched ( ((( ((visualiz*)<in>metadata ) <and> ((text*)<in>metadata ) )<and> ((cluster*)<in>metadata ))<in>metadata ) <not> ((texture*)<in>metadata ) )

& my search matched 43 of 1692897 documents.

what are 'n-grams'

| | |

From wikipedia: "An n-gram is a sub-sequence of n items from a given sequence." So the scope and granularity of their application matters greatly!

At the 'word-level', n-grams are constituted by successive groups of n words.

N-grams can be used (as in NLP) for 'efficient approximate matching.'...

svelte new zotero kicks rumply old RefMan's butt

| | | | | | |


I just remembered I have Zotero installed.

I had deactivated it because it was interfering with my RIS harvesting into Reference Manager 11 (RefMan).

I would love to compare the efficacy of retrofitting crappy Google Scholar RIS using cut-and-paste methodology from more fully indexed sources; vs. ignoring the RIS import altogether and getting Zotero to scrape it all for you.

I cant do that if Zotero gobbles up all my RIS files...So i figgured out how to make Zotero leave them alone.

"how to conduct a literature review"

Found a few inaccessible articles/books.

Google books has the first few pages of a Professional Psychologists' Handbook. Chapter 5...

visualizing textual clusters

| | | | | | | |

I started my search on google scholar, to identify recent articles on this topic.

"visualizing text clusters" produced 0 hits.

"visualizing clusters" produced 120 hits. (32 post 2006)

Found one great one:

Chen, K. & Liu, L. (2006). iVIBRATE: Interactive visualization-based framework for clustering large datasets. ACM Transactions on Information Systems (TOIS), 24, 245-294.
Georgia Tech seems to put out a lot of good stuff.

Then I decided to change tracks; to see if 'text content' or document clustering comes up:

eye movement while reading text and imagery

While starting a quick&dirty search on "gist" I found a couple of articles that pulled me towards Brian's overarching request: that I become familiar with some of the psychology literature germane to the areas we work in.

Starting with the article:

The Construction of Meaning from Text: possible effects of different reading strategies

I refined the search to:

The Construction of Meaning from Text reading strategies

I then returned to the 'gist' search.

Next I found another diverging article:

reading for gist

| | | | | | |

Got to get going on my IAT 814 and 802 term projects.

Started with the idea of reading for gist, a model principally from

O'Halloran, K. (2003). Critical discourse analysis and language cognition. Edinburgh: Edinburgh University Press.

Wanted to get a deeper view on the concept, so did a google scholar search using combined SFUBC proxies and VPNs.

Found about 32 articles with the following strategy:
