MyMemex: A web service-based personal memex system

MyMemex server consists of a web server, a data collection agent, a file handler, and a database. The data collection agent makes connections to the company web services and stores the collected "web data" (phone logs, credit card usage logs, e- mails, and so on) to the memex database. The web server enables the users to view the collected data and get the results for the queries. The users can also upload the "file data" such as image, video, and audio files locally stored in user\´s personal computer. Before saving the memex data, the web server converts the various types of data into the standard 4W1H form. The "memex event ontology" is used in the conversion. Related events tend to happen consecutively. A group of related events is called an "episode". Given a series of memex events, MyMemex employs a heuristic algorithm to solve the episode classification problem.
