There has been a lot of research targeting text classification. Many of them focus\r\non a particular characteristic of text data - multi-labelity. This arises due to the fact that a\r\ndocument may be associated with multiple classes at the same time. The consequence of such a\r\ncharacteristic is the low performance of traditional binary or multi-class classification techniques on\r\nmulti-label text data. In this paper, we propose a text classification technique that considers this\r\ncharacteristic and provides very good performance. Our multi-label text classification approach\r\nis an extension of our previously formulated [3] multi-class text classification approach called\r\nSISC (Semi-supervised Impurity based Subspace Clustering). We call this new classification model\r\nas SISC-ML(SISC Multi-Label). Empirical evaluation on real world multi-label NASA ASRS\r\n(Aviation Safety Reporting System) data set reveals that our approach outperforms state-of-theart\r\ntext classification as well as subspace clustering algorithms.", "distribution": [{"@type": "dcat:Distribution", "description": "MULTI-LABEL ASRS DATASET CLASSIFICATION USING SEMI-SUPERVISED SUBSPACE CLUSTERING", "downloadURL": "https://c3.nasa.gov/dashlink/static/media/publication/Paper_22_.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "Paper 22 .pdf"}], "identifier": "DASHLINK_244", "issued": "2010-10-13", "keyword": ["ames", "dashlink", "nasa"], "landingPage": "https://c3.nasa.gov/dashlink/resources/244/", "modified": "2025-03-31", "programCode": ["026:029"], "publisher": {"@type": "org:Organization", "name": "Dashlink"}, "title": "MULTI-LABEL ASRS DATASET CLASSIFICATION USING SEMI-SUPERVISED SUBSPACE CLUSTERING"}
