@inproceedings{garbin2005disambiguating, abstract = {This research is aimed at the problem of disambiguating toponyms (place names) in terms of a classification derived by merging information from two publicly available gazetteers. To establish the difficulty of the problem, we measured the degree of ambiguity, with respect to a gazetteer, for toponyms in news. We found that 67.82% of the toponyms found in a corpus that were ambiguous in a gazetteer lacked a local discriminator in the text. Given the scarcity of human-annotated data, our method used unsupervised machine learning to develop disambiguation rules. Toponyms were automatically tagged with information about them found in a gazetteer. A toponym that was ambiguous in the gazetteer was automatically disambiguated based on preference heuristics. This automatically tagged data was used to train a machine learner, which disambiguated toponyms in a human-annotated news corpus at 78.5% accuracy.}, acmid = {1220621}, address = {Stroudsburg, PA, USA}, author = {Garbin, Eric and Mani, Inderjeet}, booktitle = {Proceedings of the conference on Human Language Technology and Empirical Methods in Natural Language Processing}, doi = {10.3115/1220575.1220621}, interhash = {566910cb6e9745ee70da19d2ccafaffa}, intrahash = {de574cf3bff3a3748fcd9bd5a9a0f3d1}, location = {Vancouver, British Columbia, Canada}, numpages = {8}, pages = {363--370}, publisher = {Association for Computational Linguistics}, title = {Disambiguating toponyms in news}, url = {http://dx.doi.org/10.3115/1220575.1220621}, year = 2005 } @book{Man2001a, address = {Amsterdam/Philadelphia}, author = {Mani, Inderjeet}, interhash = {af9f39887357cd72ad547dfe4e6345ef}, intrahash = {67eff892b9728c22b51b108deafb2d6b}, key = {Man2001a}, label = {Automatic Summarization}, optnumber = {3}, publisher = {John Benjamins Publishing Company}, series = {Natural Language Processing}, title = {Automatic Summarization}, type = {Book}, volume = 3, year = 2001 } @inproceedings{mani2004automatcally, abstract = {The emergence of vast quantities of on-line information has raised the importance of methods for automatic cataloguing of information in a variety of domains, including electronic commerce and bioinformatics. Ontologies can play a critical role in such cataloguing. In this paper, we describe a system that automatically induces an ontology from any large on-line text collection in a specific domain. The ontology that is induced consists of domain concepts, related by kind-of and part-of links. To achieve domain-independence, we use a combination of relatively shallow methods along with any available repositories of applicable background knowledge. We describe our evaluation experiences using these methods, and provide examples of induced structures.}, address = {Geneva}, author = {Mani, Inderjeet and Samuel, Ken and Concepcion, Kris and Vogel, David}, booktitle = {Proceedings of the 3rd International Workshop on Computational Terminology}, dateadded = {2006-07-18}, interhash = {9ec83ddb1f251792d05345daa8357bf8}, intrahash = {dce5c6301943fe6c9648cf671ceb167e}, lastdatemodified = {2006-07-18}, lastname = {Mani}, month = {August}, own = {notown}, pdf = {mani04-automatically.pdf}, read = {notread}, title = {Automatcally Inducing Ontologies from Corpora}, url = {http://-new.biomath.jussieu.fr/~pz/computerm2004.html}, year = 2004 }
