# Semantic Web Issues

Here is a list of issues about the semantic web.

## Semantic Web Agents

The semantic web will not be searchable in free text. To search (or access) the semantic web, we will need some software to help us.

To use the semantic web, we will need "Semantic Web Agents" or "Semantic Web Services". These "Agents" or "Services" will help us to find what we are looking for on the semantic web.

On the semantic web, we would like to look for information about:

- The cheapest airline tickets
- Styling that would fit my car
- Books, films, and music CDs
- Weather forecasts
- Time schedules and calendar events
- Stock prices and exchange rates

In the future, for any information out there on the web; ask your "Semantic Web Agent".

## Semantic Web Security

Can I trust a seller on the semantic web. Can I trust a buyer on the semantic web?

To solve I will need access to more RDF files:

- Credit card information
- Bank information
- Semantic records
- Social Security information

Source | Person ID | Person Name | Status
--- | --- | --- | ---
Citybank | 11223344 | John Smith | trustworthy
VISA | 11223344 | John Smith | trustworthy
Recorded | 11223344 | John Smith | unknown
US Social Security | 11223344 | John Smith | born 10-10-1962

By using RDF files like this, my "Semantic Web Agent" can determine if I can trust the person I am dealing with.

(the "Recorded" information could be supplied by Internet trading companies like eBay, Amazon or the like)

## Payment

To serve the semantic web, payment methods have to be developed.

Internet accessible "Deposit Accounts" could be a solution to this.

A deposit account is an account that can only receive deposits. It could be made accessible for everyone on the Internet, and everyone could deposit money to your account only knowing your ID (or your email address, much like PayPal).

Using this payment method everyone could publish their bank account number over the Internet and sell their car without any middleman.

What will be the future of Internet banking?

## OWL - Your Web Thesaurus

Scenario:

- You want to sell a book
- You open your OWL agent
- You entered “Book” in the category
- A new screen is asking you to fill out information about the book
- You fill out the ISBN number written on the book
- You select "used", and "condition as new", and hit return
- Your OWL agent automatically fills out the rest
- Author, year, pages, ...... all information is now complete
- Your OWL agent has collected all the information you needed to sell the book
- You click on Auction.

You can read more about OWL in our RDF tutorial.

## Your Auction Agent
