Automatic Class Labeling for CiteSeerX
2013
2013 IEEE/WIC/ACM International Joint Conferences on Web Intelligence (WI) and Intelligent Agent Technologies (IAT)
Preserved Fulltext
We evaluate three methods by comparing the suggested labels with human-assigned labels for exist-ing categories. ...
To address this problem, we are exploring ways to automatically expand the CCS ontology. Previous work has focused on using clustering to automatically identify the new clas-ses. ...
Our contributions are as follows: (1) we describe an automatic ontology expansion technique based on clustering; and (2) we evaluate a new labeling algorithm to label the newly created subclasses. ...

In this paper, automatic text summarization with K-means clustering techniques is presented by employing two different distance measurement methods (Euclidean and Manhattan). ...
The preprocessed document is converted into vector representation using tf-idf technique and k-means clustering is applied using Euclidean and Manhattan distance measures to generate summary. ...
The future work can consider automatic determination of number of clusters to enhance K-means performance. Also, other distance measures can be considered for comprehensive evaluation. ...

But, more work needs to be done to establish theoretical basis for the use of automatic classification techniques as also for the construction of automatic classification schemes. ...
The results of early experiments have been rather hard to interpret and evaluate. At present, there is a realization that automatic classification is desirable in principle. ...

This paper proposes an automatic query generation (AQG) system for Arabic language. The system generates a set of queries of different length that were applied on a query expansion system. ...
Usually data sets of queries for a specific corpus are generated using the human experiences. Manual queries are more accurate than automatic one's, but they require a huge effort in the huge corpus. ...
A lot of methods and techniques have been built to construct queries manually, but only few methods exist for automatically query construction. ...

The application of cluster algorithms based on the selection of representative objects has a potential for automatic theme recognition, text abstracting and text linking, even beyond the legal field. ...
Techniques are developed for identifying and extracting relevant information from the cases. A broader application of these techniques could considerably simplify the work of the legal profession. ...
