To browse the knowledge base:

• Click on a category (or relation) from the list in the left-hand panel. This will bring up a list of facts that NELL has read that are relevant to that category (or relation).
• By default, facts are sorted by NELL's confidence that they are true. You may also sort alphabetically, by iteration, or by the date at which that fact was first read on the Web. To do so, simply click on the corresponding column heading.
• You may also search entities in the KnowledgeBase using the search box in the upper-right.
• Click on an entity (noun phrase) to bring up a detailed view of all the facts that are known about it.
• The "facts" that are shown in light grey (like this) are things that NELL has found some weak evidence for somewhere the Web, but doesn't quite believe to be true.
• For each fact in the detailed view, we also present some "source" information, describing which subsystems (e.g., CPL, SEAL, CMC, RL) were used in contributing to NELL's understanding of this fact. This includes the system iteration, confidence, and date at the time it was read, plus some details (e.g., web page links or text patterns).

For more technical details on the NELL system and how it reads the Web, see our AAAI 2010 paper.
