Abstract: Systems, methods and computer program products for controlling access to electronic content on a client device are provided. Whether access to electronic content is allowed or blocked is based on information and processes performed at the client device. Controlling access to electronic content on a client device can involve locally determining whether access to the electronic content will be allowed, blocked, or will depend upon further analysis performed by a remote device, such as a server. If a webpage is requested, for example, a client device may compare the URL address of the requested webpage, along with keywords and phrases found on the webpage, to locally-stored updateable lists of banned URL addresses and banned keywords and phrases to determining whether access to the electronic content will be allowed, blocked, or will depend upon further analysis.

Abstract: Systems, methods and computer program products are provided for assigning content category scores to nodes of a linked database. The nodes of the linked database include linking nodes and linked nodes. Each linking node is assigned a linking node score for each content category. The linking node score for each content category represents a degree of relevancy of the linking node to the content category. Each of the linked nodes is linked to by at least one of the linking nodes. Each linked node is assigned a content category score for each content category. The content category score for each content category is based on the linking node score for said content category of each linking node that links to the linked node.
