I am currently interested in time series analysis as it seems to be a great feature for all kinds of software to report unexcpected events. My first go is rather simple with just taking the last 90 datapoints and then look whether it differs more than 2 or 3 times from the standarddeviation. Does anyone have a simple approach for more sophisticated time series analysis? or rather, links and book recommendations?

Does anyone know whether there already exist some publicly available libraries / classifiers, which can be used to determine the sentiment (positive, negative, neutral) of a text passed to them? The task is not exactly simple, but it would be a great tool for all kind of web services.

I am currently working out what kind of public data could be imported into an analytics tool to make it more informative. For example, I have noticed that the revenue of a site usually drops if it's really hot outside, so I figured offering weatherdata would be helpful as a possible explanation for drops in traffic and revenue. Do you have any other ideas or wishes for data you'd like to see beside your website-data?

Thanks for all answers.

I am curently researching a few patents since our company is considering to make the leap and attract some american companies as customers. We are providing a web analytics solution which works by putting a pixel into the website to be tracked. Said pixel is stored on our servers in Europe. Now I wonder how patents on webanalytics are applicable, when they are filed in the United States. Our company would not operate an office there, we do not even have servers there. The client computers would receive their pixel from europe and an american company would access a frontend in europe or collect data via SOAP.

If we now attract american customers and provide stats for american websites are we then suddenly violating patents, because they are american? I don't understand how the international fences are drawn and before we start setting out to the american market we certainly will ask a lawyer, but my experiences with lawyers were rather bad when it came to such technical and complicated issues they rarely understand. So if anyone of you has some reasonsable speculations to offer or could point me to a source or a case, let me know.

Do you know of any Open Souce Social Network Frameworks? It seems silly to implement the same funcitonality over and over again, I'd rather concentrate and implement innovative ideas, instead of the xth messaging system, etc. If you have any sugestions, experiences and recommendations, please post them. I'd prefer to be able to host it myself, it should be open source and easily extendable in order to add original features.
