The demo given by Anand on semantic search of feeds using OpenCalais was very interesting.<br>The fact that his app essentially did something that <a href="http://www.feedly.com/" target="_blank">Feedly</a> ( based on Google Reader ) does piqued my interest.<br>
<br>Feedly too uses OpenCalais to get semantic information on a blog post and for search.<br>If you use Google Reader as a RSS reader then you have to check out Feedly.<br><br>Anand used <a href="http://code.google.com/p/python-calais/" target="_blank">python-calais</a> for communicating to the <a href="http://opencalais.com/documentation/calais-web-service-api/api-invocation/rest" target="_blank">OpenCalais API</a>.<br>
Anand then showed how OpenCalais categorized the input text into entities, topics and relations.<br>With every entity OpenCalais attached a percentage that indicated how sure it was on the element being the entity<br>whose identity was given by a URL. For instance, there is a URL identiying the entity "Android" as a product.<br>
<br>Open Calais is exciting new technology that has made information gathering applications like Feedly and <a href="http://www.klezio.com/" target="_blank">Klezio</a> possible.<br>Another application is <a href="http://tagaroo.opencalais.com/" target="_blank">Tagaroo</a> a wordpress plugin that automatically generates tags as you type your blog post.<br>
<br>In the meetup Anand said that the current state-of-the-art of semantic web is not even 5% of its potential. A quick search of the term<br><a href="http://www.readwriteweb.com/fastsearch?search=imagine+semantic+web&x=0&y=0" target="_blank">imagine semantic web</a> on ReadWriteWeb shows that a lot of businesses and visionaries are betting big on semantic web and know that<br>
it has a lot of potential.</blockquote><div><br>Excellent summary. Btw, I am summarizing the links I used in the meeting.<br>There was no presentation, I did an ad-hoc talk, so these could be of help.<br><br><a href="http://www.opencalais.com">http://www.opencalais.com</a> - OpenCalais<br>

</div>The opencalais session was good. I'm going to tell my colleagues about<br>
this, and they'd surely explore it more.<br>
<br>
Anand and Ramdas have asked that we have sessions again with more<br>
detail. I agree, since the scant amount of ZFS that I showcased today<br>
was in itself radically different from what we all know from other<br>
file systems.<br>
<br>
I request feedback from other attendees on today's ZFS session. Please<br>
let me know what else you'd have liked me to cover at an introduction<br>
level.<br></blockquote></div><div><br>We had a good meeting. There were some initial hiccups with the<br>projector but moving to a separate meeting room solved it.<br><br>I presented a brief introduction to semantic web and showcased the<br>
OpenCalais API using python-calais. I showed how to extract semantic<br>concepts (categories) from existing data using the API.<br><br>I went on to demo my application which listens to a couple of mobile<br>phone news feeds and uses semantic information returned by OpenCalais<br>
to provide specific natural language queries (not exactly NLP there yet,<br>but I am simulating NLP like queries) which return specific answers.<br><br>The demo showed making a query on "cost of motorola android" and<br>
this returning the specific data requested on the price of the most<br>recent motorola android mobile phones.<br><br>I will wait for some other attendee for their feedback on how good<br>this was rather than making the comment myself :)<br>
<br>This was followed by a very good session by Sriram and Moinak on<br>the capabilities of ZFS. I don't want to get into details, but I was blown<br>away by the capabilities of ZFS. I had only read about it before and never<br>
seen it in action, so when Sriram showed how to increase the storage<br>of an existing volume by adding another device and just adding it to<br>the volume using "zfs add" it was just too good to believe. ZFS<br>
makes those actions which could take hours using Linux ext3 <br>look trivial and done within seconds...!<br><br>We started the ZFS session a bit late i.e around 5.30 pm so there<br>was not much time to showcase all the bits planned. We dispersed<br>
around 6.10 pm.<br><br>We were 7 attendees in total.<br>Â </div><div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
