We will attempt to extract these predicates and relations• isAuthor(X)

• isPaperTitle(X)

• isConferenceName(X)

• publishedAt( <paper>, <conference> )

• authorOf (<author> , <paper> )

By looking at these Web pages:

• An author’s publication lists (on their home page)

• Conference accepted papers list (on the conference Web page)

AAAI-05 Paper List

Then we look for patterns…

<author> and <author>, <title>.

<author> , <author>, <author> and <author>, <title>.

<author> , <author>, <author> and <author>, <title>.

But…

• Maybe the patterns are wrong, so look for some more evidence…

• Once we have enough evidence we can add it to our knowledge base.

…And around 100 other citations in roughly the same format …

Conclusion

• Redundancy = # of authors + 1• Seems to be very precise since titles usually

do not have many spelling variations.• Help to find alternate name spellings

– Could there be a “Q. Yang” and a “Qiang Yang” with nearly identical publications?

• Works for other fields also (e.g. History)
