Name Disambiguation in Digital Libraries

Tan Yee Fan

2005 October 19

WING Group Meeting

digital libraries
Digital libraries
  • DBLP, Citeseer, etc.
  • Information is stored as metadata records to facilitate searching
    • Author names
    • Titles
    • Publication titles
  • Inconsistency in metadata records hinders searching
    • Abbreviation of names and publication titles
    • Typographical errors
are they the same author
Are they the same author?
  • Danny Poo
    • Danny C. C. Poo, Teck-Kang Toh, Christopher S. G. Khoo, Glenn Hong. Development of an Intelligent Web Interface to Online Library Catalog Databases. APSEC 1999: 64-7
    • Danny Chiang Choon Poo, Isaac K. C. Tan. Design of an Automatic Annotation Framework for Corporate Web Content. APSEC 2004: 384-391
  • Hui Yang
    • Maan A. Kousa, Ahmed K. Elhakeem, Hui Yang. Performance of ATM networks under hybrid ARQ/FEC error control scheme. IEEE/ACM Trans. Netw. 7(6): 917-925 (1999)
    • Hui Yang, Tat-Seng Chua. QUALIFIER: Question Answering by Lexical Fabric and External Resources. EACL 2003: 363-370
who am i i am who
Who am I, I am who?
  • Author name disambiguation
    • Given a large number of citations, how to determine which name is which author?
  • Closely related problem: citation matching
    • Given a large number of citations, how to determine which citations refer to the same papers?
  • Solutions must be scalable
    • DBLP has more than 660,000 citations
    • Citeseer has more than 730,000 documents
ideas
Ideas
  • Idea 1: determine the research field
    • Unfortunately, paper titles have limited words and some conferences tend to be broad
  • Idea 2: use coauthors information
    • Likely that an author will collaborate with a selected group of people
    • This group will likely publish a number of papers together
  • To find the similarity of coauthor lists
forward direction m kan m y kan min yen kan
Forward direction:M. Kan = M.-Y. Kan = Min-Yen Kan
  • Problem
    • Pairwise comparison on all the coauthor lists is very expensive (few days also cannot finish)
  • Solution
    • Soft clustering on the coauthor lists using some cheap distance measure
    • Then perform pairwise comparison within the clusters
    • What is a good soft clustering algorithm?
backward direction this hang cui is not that hang cui
Backward direction:This Hang Cui is not that Hang Cui
  • Difficult to determine using the metadata alone without external resources
    • Many authors have several distinct research areas
    • Each research area with different collaborators
  • Currently investigating what kind of external resource to use
    • Goooooooooogle for URLs?
the end
The end
  • But the research has just begun…
