Global versus Local Call Admission Control in CDMA Cellular Networks

Global versus Local Call Admission Control in CDMA Cellular Networks

Date: July 2004
Creator: Akl, Robert G. & Parvez, Asad
Description: This paper discusses global versus local call admission control. Abstract: We design and implement global and local CAC algorithms for CDMA networks, and compare their network throughput for various mobility scenarios. The global CAC algorithms is inherently optimized and uses global information in making every call admission decision; it yields the best possible performance but has an intensive computational complexity. The design of the local CAC algorithm uses global information but its implementation in each cell uses only local information; it only requires the number of calls currently active in that cell and thus is very simple to implement. We show that our optimized local CAC algorithm achieves almost the same performance as our global CAC algorithm for a given call arrival rate profile.

Graph-based Ranking Algorithms for Sentence Extraction, Applied to Text Summarization

Graph-based Ranking Algorithms for Sentence Extraction, Applied to Text Summarization

Date: July 2004
Creator: Mihalcea, Rada, 1974-
Description: Abstract: This paper presents an innovative unsupervised method for automatic sentence extraction using graph-based ranking algorithms. We evaluate the method in the context of a text summarization task, and show that the results obtained compare favorably with previously published results on established benchmarks.

The SENSEVAL-3 Multilingual English-Hindi Lexical Sample Task

The SENSEVAL-3 Multilingual English-Hindi Lexical Sample Task

Date: July 2004
Creator: Chklovski, Timothy; Mihalcea, Rada; Pedersen, Ted & Purandare, Amruta
Description: This paper describes the English-Hindi Multilingual lexical sample task in SENSEVAL-3. Rather than tagging an English word with a sense from an English dictionary, this task seeks to assign the most appropriate Hindi translation to an ambiguous target word. Training data was solicited via the Open Mind Word Expert (OMWE) from Web users who are fluent in English and Hindi.

TextRank: Bringing Order into Texts

TextRank: Bringing Order into Texts

Date: July 2004
Creator: Mihalcea, Rada & Tarau, Paul
Description: In this paper, the authors introduce TextRank, a graph-based ranking model for text processing, and show how this model can be successfully used in natural language applications. In particular, the authors propose two innovative unsupervised methods for keyword and sentence extraction, and show that the results obtained compare favorably with previously published results on established benchmarks.
