This work investigates cluster labeling enhancement by utilizing Wikipedia, the free on-line encyclopedia. We describe a general framework for cluster labeling that extracts candidate labels from Wikipedia in addition to important terms that are extracted directly from the text. The labeling quality" of each candidate is then evaluated by several independent judges and the top evaluated candidates are recommended for labeling. Our experimental results reveal that the Wikipedia labels agree with manual labels associated by humans to a cluster much more than with significant terms that are extracted directly from the text. We show that in most cases even when human's associated label appears in the text pure statistical methods have difficulty in identifying them as good descriptors. Furthermore our experiments show that for more than 85% of the clusters in our test collection the manual label (or an inflection or a synonym of it) appears in the top five labels recommended by our system.

"Cluster labeling withWikipedia is extremely successful, as shown by our results, especially in collections of documents whose topics are covered well by Wikipedia concepts. For domain specific collections, with topics that are not com- pletely covered by Wikipedia, the proposed candidates may hurt the system’s performance due to their irrelevance to the documents’ topics. For such collections, an intelligent decision should be made regarding the use of Wikipedia or another external resource; alternatively, a choice could be made to focus only on inner terms for labeling. The deci- sion should be made by analyzing the given collection with respect to Wikipedia. Developing such a collection specific decision making as part of the labeling framework is left for further research."
