Failed experiments in reports digestion, annotation and Entity extraction on the cheap

I've been looking around for ways to digest and annotate and make lengthy reports more usable for years.

One of the main ways to do with would be through named entity extraction running the report through a program and extracting all key words, and sorting them into proper names, places, organisations, companies etc. I have looked around and there are lots of university thesis papers on how to do it but it seems nobodies cracked it, unless mega corporations maybe able to do it on a industrial level. You could also paste it all the report into a wiki and hope people will annotate and link sections of the report, but wiki's aren't easy to use and there no way to automate it even a little that I know of.

Entity extraction has come back in vogue at the moment particularly in conjunction with the rise of the semantic web and there a number of companies who now offer it, Yahoo YQL, AlchemyAPI and Open Calais. There have demos you can try to see what it extracts Alchemy API demo and Open Calais demo but then it give you REST urls to actually use them and I don't know what to do with REST urls and they rarely give examples.

Open Calais has a wordpress plugin which will try and extract tags for your blog it works ok and I figured actually a blog would be good way to present a report, and give me the structure I would need, I could also dole out the pages reports via rss.

Open Calais actually has an WP Calais Archive Tagger too, So I found Mass page uploader plugin for WP and got some dense reports from thestory who who have gone to the effort of getting government reports, scanning and OCR'ing them, Like the Fas Report INV 37, into excessive spending by the Irish state training body.

I downloaded it from scribd a document pdf store website which also stores files in txt format. I followed the instructions of the mass page maker plugin useing Notepad++ to split each page in to a separate blog post in a in the mass page maker syntax a comma separated file(.csv) file and uploaded it to a blog.

Then I ran the calais archive tagger over each page, it extracts about 10-20 tags from each page, it often splits name and organisation up, I tried some YQL based and other auto taggers plugin on it too. Auto tagging WP plugins . They don't work very well.

I did have this blog, with each page of the DDDA report into state bodies bad property deals with private groups in the Dublin docklands, posted and tagged on my domain but had to delete it because it was getting in the way. An earlier attempt *shrug*

There are many other wordpress plugins I tried, for group tagging the tags into entity like groups of people and companies, for locating every place mentioned in the text on a google map. There are a number of plugins for wordpress to create taxonomy of words and glossaries.

Annotation
Wordpress does allow to leave comments at the end which may elucidate a report but in length of text it may be easier to annotate the text directly on to it. I came across WP plugin that does just that. Digress it Example, which has a floating side commenting widget which annotates each paragraph of post. There are another couple of previous versions of this plugin he has developed but I couldn't get any of them to work. There is particular apache setting most shared hosting services don't have and I can't change it or get any of suggested fixes to work stably.

Document cloud, seems to be professional answer to all these things and investigative journalism websites like Pro Publica are already using it for annotation and it seems to be open source and they say it will do entity extraction but its not ready yet.

So dear wind, I couldn't get entity extraction to work very well, nor annotation, maybe I'll just have to concentrate and read the reports :/

Detailed reading of the reports is what enable The Story reporters Mark Coughlan and Gavin Sheridan to produce article like this one about renting of buildings from business partners of FAS employees from the dense reports, and tracking down the details, I guess thats what investigative journalism is.

Irish GeoRSS News feed: YahooPipes vs GoogleMaps

Testing to see if I can embed a geoannotated news rss feed into my blog, and testing the difference between Yahoopipes version and Googlemaps version on an Irish breaking news feed.

Feck yahoo pipes doesnt offer embedding for free yet, I'll should just try georss and yahoo map api, hmm need a server access for that, sure everybody outputs the result to google maps anyway. Here's what a Yahoo pipes map looks like Irish Examiner breaking geonews Yahoo pipe

Back to google maps thanks to nearby.org.uk and lots of detailed but basic how-tos at Mike at Blackpool Community Church Javascript Team!?.

okay so got that working its pretty simple but making it usable for an Irish website its what I want to do, so I can put it in the corner and a small list of the stories below from the same rss feed and be able to click those links with a # tag and have a small icon where you can zoom down to street level which would make it useful for local blogs.I figure out how to put a link in the infowindow directly to the story. So it doesn't work very well, but there are different versions and if you go to georss homepage you can add the locations as they come up so you can improve its hit rate yourself. There are also javascript api that allow for infowindow to display outside the map so you don't have to scroll to read it etc.

Here's a few attempts at refinement A GeoRSSS plus clickable sidebar list
