We study this problem in detail by exploring a large number of different feature sets and algorithms on several datasets. We also show that the inherent overlap between topics and the sparsity of the information in URLs makes this a very challenging problem. Web page classification without a page’s content is desirable when the content is not available at all, when a classification is needed before obtaining the content, or when classification speed is of utmost importance. For our experiments we used five different corpora comprising a total of about 3 million (URL, classification) pairs. We evaluated several techniques for feature generation and classification algorithms. The individual binary classifiers were then combined via boosting into metabinary classifiers. We achieve typical F-measure values between 80 and 85, and a typical precision of around 86. The precision can be pushed further over 90 while maintaining a typical level of recall between 30 and 40.","lang":"eng"}],"doi":"10.1145/1993053.1993057","day":"01","extern":"1","volume":5,"author":[{"first_name":"Eda","last_name":"Baykan","full_name":"Baykan, Eda"},{"id":"540c9bbd-f2de-11ec-812d-d04a5be85630","first_name":"Monika H","last_name":"Henzinger","orcid":"0000-0002-5008-6530","full_name":"Henzinger, Monika H"},{"last_name":"Marian","first_name":"Ludmila","full_name":"Marian, Ludmila"},{"first_name":"Ingmar","last_name":"Weber","full_name":"Weber, Ingmar"}],"issue":"3","_id":"11673","scopus_import":"1","title":"A comprehensive study of features and algorithms for URL-based topic classification","intvolume":"         5","publication_status":"published","date_created":"2022-07-27T13:48:11Z","article_processing_charge":"No","quality_controlled":"1","article_type":"original","publisher":"Association for Computing Machinery"}]
