Tang, Rong; Ng, K. B.; Strzalkowski, Tomek; Kantor, Paul B. – Proceedings of the ASIST Annual Meeting, 2003
Reports preliminary results of a study to develop and automate new metrics for assessment of information quality in text documents, particularly in news. Through focus group studies, quality judgment experiments, and textual feature extraction and analysis, nine quality aspects were generated and applied in human assessments. Experiments were…

Seki, Kazuhiro; Mostafa, Javed – Proceedings of the ASIST Annual Meeting, 2003
Proposes a method for protein name extraction from biological texts. The method exploits hand-crafted rules based on heuristics and a set of protein names (dictionary). The approach avoids use of natural language processing tools so as to improve processing speed. Evaluation experiments were conducted in terms of: accuracy, generalizability, and…

Cole, Charles; Leide, John E.; Nwakamma, Emeka; Beheshti, Jamshid; Large, Andrew – Proceedings of the ASIST Annual Meeting, 2003
Presents preliminary results from a study of an information need identification system for interactive information retrieval for undergraduates researching a history topic. Concludes that the query taxonomy must include levels of topic specificity because while general topic-based queries are inappropriate as query terms, more specific topic-based…
