Using Tag Co-occurrence for Recommendation
2009 Ninth International Conference on Intelligent Systems Design and Applications, 2009Tagging with free form tags is becoming an increasingly important indexing mechanism. However, free form tags have characteristics that require special treatment when used for searching or recommendation because they show much more variation than controlled keywords. In this paper we present a method that puts this large variation to good use.

Since 80% of all information in the World Wide Web (WWW) is in textual form, most of the search activities of the users are based on groups of search words forming queries that represent their information needs. The quality of the returned results -usually evaluated using measures such as precision and recall- mostly depends on the quality of the ...

Co-occurrence of Pneumococcal Keratitis and Dacryocystitis
Cornea, 1999To evaluate the specific risk factors responsible for the development of pneumococcal keratitis.In a retrospective analysis of 383 patients of culture-proven bacterial keratitis, seen between 1991 and 1995, 139 had monobacterial isolates on culture. We analyzed the various predisposing factors in these patients, with special emphasis on the patency of ...

Co-occurrence flow for pedestrian detection
2011 18th IEEE International Conference on Image Processing, 2011The last few years have seen considerable progress in pedestrian detection. Recent work has established a combination of oriented gradients and optic flow as effective features although the detection rates are still unsatisfactory for practical use. This paper introduces a new type of motion feature, the co-occurrence flow (CoF).

Co-Occurrent Features in Semantic Segmentation
2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2019Recent work has achieved great success in utilizing global contextual information for semantic segmentation, including increasing the receptive field and aggregating pyramid feature representations. In this paper, we go beyond global context and explore the fine-grained representation using co-occurrent features by introducing Co-occurrent Feature ...

Euclidean embedding of co-occurrence data
J. Mach. Learn. Res., 2007Summary: Embedding algorithms search for a low dimensional continuous representation of data, but most algorithms only handle objects of a single type for which pairwise distances are specified. This paper describes a method for embedding objects of different types, such as images and text, into a single common Euclidean space, based on their co ...

Proceedings of the Workshop on Use of Context in Vision Processing, 2009
Head pose and gesture offer several conversational grounding cues and are used extensively in face-to-face interaction among people. To accurately recognize visual feedback, humans often use contextual knowledge from previous and current events to anticipate when feedback is most likely to occur.
