Introduction

• reliable source of information
• accessible to everyone around the world
• most up-to-date online encyclopedia
• disadvantages

3
See Also

• list of similar or related articles to current
  article
• urges users to continue browsing and reading
  articles on the page itself
• user created list

4
Thesis

• users on similar topics create connections to the
  same articles
• by comparing two articles connections we could
  conclude how similar these two articles are

5
Goal

• creation of an automatic recommendation system
  for the See also section based on soft
  clustering of documents

Research

• 5,012 articles
• 509 clusters
• evaluation
• compared against human created connections

10
Research

• tokens as vector features
• document similarity threshold 0.5
• connections within Wikipedia treated as separate
  tokens with extra weight when comparing the
  articles

11
Research

• clusters in three categories
• clusters with no real value
• partially relevant clusters
• well-formed clusters

12
Clusters with no real value

• generated clusters not usable
• subjects in completely different theme areas
• clusters which contain too many articles
• St. Peter, Saint-John Perse, General Staff of
  Armed Forces of the Republic of Croatia, French
  Guiana, Marine mammals
• Eurasian Avars, Psychology, birds

13
Partially relevant clusters

• some articles within this kind of clusters
  thematically related
• remaining articles are not bound with the same
  subject or they dont involve the same or similar
  area
• Croatian Football Team, Parliamentray elections,
  Orthography, Presidential Elections, Croatian
  Academy of Science and Arts

14
Well-formed clusters

• articles connected to the same subject
• Olympic Games in Tokyo, London, Barcelona,
  Atlanta, Athena, Beijing, Summer Olympic Games
• football teams
• Airbus airplanes

15
Observations

• Wikipedia users more often create connections on
  more general and more obvious terms

16
Conclusion

• the procedure cannot be regarded as being
  successful enough for an unsupervised
  implementation on articles in Croatian Wikipedia
• most likely the algorithm would be more
  successful in a strictly supervised encyclopedia
