BlueSalamander writes "Tim O'Reilly just did an interview with Devin Wenig, the CEO-designate of Reuters. With no great enthusiasm I started to read yet another interview on how the semantic web was going to make everything great for everybody. Wenig made some good points about the end of the latency wars in news and the beginning of the battle for automatically detecting linkages and connections in the news. Smart news, not just fast news. Great stuff — but just more words? Nope — a little searching revealed that Reuters just opened access to their corporate semantic technology crown jewels. For free. For anyone. Their Calais API lets you turn unstructured text into a formal RDF graph in about one second. I ran about 5,000 documents through it and played with a subset of them in RDF-Gravity. The results were impressive overall. Is this the start of the semantic web getting real? When big names and big money start to act, not just talk, it may be time to pay attention. Semantic applications anyone? The foundation appears to be here."

I think you are missing the point of Semantic Web: you can refer or link to an object, not just document.
The company declares its URI. Now, If you are writing an article about this company, you can uniquely identify it and every web crawler knows *exactly* what company are you talking about. If the URI for the company is a hyperlink to its web site, then it can't be abused: the company itself declares what it is. The unique URI will in fact be a link to some file with information about company (maybe an RDF file -- doesn't really matter for the concept)
The system can (and will be abused) in the same way as an old web: irrelevant links, words, concepts -- nothing new for the crawler and can be defeated with existing techniques.
Again, Semantic Web = Links between concepts, not just documents, so please do not bury the good idea under the pile of misunderstanding.

Semantic webs might be OK for small document sets where you can visualy search tags and click them. Want to look up something about monkeys? Look for the tag that says monkeys (or maybe find primates first, then monkeys) and click it.
But for huge data sets this sucks. After a smallish number of documents & subjects it must be far easier to type monkeys in search box and have Google etc do the search.
This might work for handling some queries, but will suck supremely for complex queries over large data sets (eg. the whole www).

Well, if we are very forgiving we can get this kind of thing happening with current technology, we just have to supply all the "content" in a form that our primitive algorithms can handle. The Semantic Web is that. Maybe around the 3rd generation of these algorithms we might be ready to do the translation to machine form automatically.. maybe not.. but at least the Semantic Web people are again talking about translation.. was a time when they all said it was a fruitless path and the best way was to just supply applications for creating machine readable content easily.

On first read, I like what they are trying to do, but I see so many problems with what they are thinking, and I am not a web designer in any sense.
First, I don't have a problem finding things to buy on the internet. The problem is, signal to noise ratio. There are TOO MANY google results for something like 'plasma tv.' No matter what kind of RDF is used, it will be abused by people who want their URL to show up in your search for whatever reason. I think someone touched on this earlier a little in this thread, but it deserves repeating.
Second, can you imagine a scenario where, say, best buy or fry's uses some 'semantic web' application to do real time web searchable updates of their inventory? That's what would have to happen for this to work, and do something that isn't already possible.
Right now, I can search for 'plasma tv' in google or ebay. Then I can call my local retailers to see if they carry that item, and have it in stock. In order for this system to make any kind of tangible change in the example given, retail chains would have to update their inventories online, whenever a purchase is made, or new items delivered to the store.
It's an interesting idea. I wonder if the retailers would go for it? All it means for them is fewer people comming into their stores...sounds like that would hurt sales.
I also hate internet hype. I really fouls things up, more than some want to acknowledge. I try to keep my 64 year old dad educated enough to buy coffee beans on ebay, check email, look at news, etc. Every time he sees 'symantic web' or 'web 2.0' in the media, it just confuses him, and I imagine, people like him who just use the net for basics like online bill pay, ebay, etc. He doesn't need a new buzzword to motivated to shop online or whatever.

Combine that kind of latent semantic analysis of global human text with conceptual knowledge representation and inference

create a software program that could start to get a basic semantic understanding of documents and document relationships
in the ordinary "dumb" web.
Could the proponents of the semantic web please tell me what it will add to this?
My basic proposition is that if an averagely intelligent human can infer the semantic essence (the gist, shall we say), of
individual documents, and relationships between documents on the web, why can't we build AI software that does
the same thing, and then reports its results out to people who ask.

I understand being jaded about internet hype and buzzwords but I'm still surprised that after nearly eighty comments there doesn't seem to be anyone who has anything to say other than "vaporware" and "it won't work because of the spammers." Yes, maybe it has been overhyped and yes it is taking a while for the envisioned ideas to come to fruition but that doesn't mean that those ideas aren't worthwhile.
I'll use the following example because I recently had to do this with non semantic tools. Lets say you wanted to see how good or bad a job a transit agency is doing in its city in comparison to other similar cities. A couple of metrics you might use to find similar cities would be population size, population density and land area. Google doesn't do a good job with something like that. You end up needing to search for cities individually and then finding their data points. Or you can find a list of cities ranked by population or population density. If you search on Google for something like that you end up at one of the Wikipedia lists. These lists are helpful but....still lacking. They don't contain all the cities you need or they don't provide a way to look at multiple data sets at the same time. The lists are also compiled by hand and aren't automatically updated when the information on the city page is changed. The data is in wikipedia though. Every city page lists that information in a little box near the start of the article. But how do I take this data that is in Wikipedia from the form that its in into a form that I can use to find what I need to know? Enter the semantic web.
Lets say that wikipedia, or at least the parts dealing with geography, were semantic. Now, there are tens of thousands of pages describing countries, regions, states, counties, parishes, cities, towns and villages. Then those pages are translated into many other languages. Some of the data that these pages contain is of the same type . They all contain the name of the locality, latitude, longitude, size, population size and elevation. For data such as this it would be pretty easy to have a form to enter the data into as opposed using the usual markup and the form could put the data into the proper markup for the page and the proper RDF. Once the data is in proper RDF form it would be easy to automate the process of updating translations of that page with the new data as well as updating any pertinent lists. It would also make it easier for people who want to analyze or use the data because they would be able to access it much more easily.
But nobody really wants machine readable access to this information, you might say, except for the random geek and researcher. I would disagree. Lets say you're using a program like Marble which is similar to Google Earth in some ways but is completely open source. If they wanted to display the population of a city when you hover over it they would currently have to create and maintain their own dataset or they'd have to write a parser to extract it from wikipedia. Neither of those options is particularly easy at the moment but if the information was in semantic form on wikipedia it would be a piece of cake.
The strength of the semantic web isn't, in my opinion, going to be AI like personal agents or anything like that. It'll be things that in many ways are already here. Like Yelp putting geotags on the restaurants they reviews and apps like Google Earth taking that data thats available in machine readable (Semantic!) for to overlay that data on a map so that you can see whats nearby. It'll be applications doing the same with the geotags from flickr. Its really useful mashups like http://www.housingmaps.com/ [housingmaps.com]. Its the transit agency putting realtime bus data up in semantic form so you can see on your iphones google map how far away the bus is. So yeah, maybe the semantic web is overhyped but that doesn't mean there isn't a lot of substance there, too.

We use RDF stores instead of databases in some places as they are very good at representing graph structures, which are a real pain to real with in SQL. You often hear the "what can RDF do that SQL can't" type arguments, which are all just nonsense. What can SQL do that a field database, or a bunch of flat files can't? It's all about what you can do easily enough that you will be bothered to do it.
A fully normalised SQL database has many of the attributes of an RDF store, but
a) when was the last time you saw one in production use?
b) how much of a pain was it to write big queries with outer joins?
RDF + SPARQL [w3.org] makes that kind of thing trivial, and has other fringe side benefits (better standardisation, data portability) that you don't get with SQL.
