UMLS and Its Application in Field of Intelligent Retrieval
Bai Haiyan, Wang Li, Liang Bing
2012,
28
(4): 1-9. DOI:
10.11925/infotech.1003-3513.2012.04.01
Abstract
This paper mainly investigates UMLS's composition and characteristics, emphasizes on application cases of UMLS in field of intelligent and semantic retrieval, and analyses the scene designs, technology realization and application effects of these cases, in order to provide references for design and development of intelligent retrieval system based on integrated knowledge organization systems. The application of UMLS in field of intelligence and semantic retrieval mainly includes: (Ⅰ)query expansion, such as synonym expansion, hierarchical structure expansion and phrase segmentation expansion; (Ⅱ)semantic retrieval, based on concepts and relationships between concepts;(Ⅲ)question-answering search, including question analysis, document retrieval, sentence selection and semantic clustering.

An Online Tutoring System Mining Discussion Logs to Stimulate Students Thinking
Li Jia, Zhang Pengzhu, Li Xinmiao, Jihie Kim
2012,
28
(4): 10-16. DOI:
10.11925/infotech.1003-3513.2012.04.02
Abstract
In order to stimulate student thinking and reduce service response time, the authors propose an online recommendation method that mines relevant information from discussion logs. The proposed method consists of six steps, namely technique term hierarchical tree building, task term extraction, document segmentation, feature extraction, topic identification, and document score calculation. Two experiments are designed to evaluate the proposed system. In the first experiment, three different document recommendation algorithms (i.e., TF-IDF, TF-IDF + topic filtering, TF-IDF + LSA + topic filtering) are compared, and the TF-IDF + topic filtering algorithm gets the best performance. In the second experiment, the proposed system is applied to one semester of online discussion, and the proposed system leads to better discussion participation as well as a higher level of perceived usefulness and ease of use. The results indicate that moderated relevant discussion record can be mined automatically, and providing such information can stimulate student's thinking and discussion.

Implementation of Ontology-based TMC Diagnosis Reasoning by C-F Theory
Ni Ping, Lu Yuhong
2012,
28
(4): 22-28. DOI:
10.11925/infotech.1003-3513.2012.04.04
Abstract
According to the diagnosis process, this article analyzes the concepts and properties of TCM knowledge, constructs the Ontology for TCM by Protégé. Based on the Ontology, it proposes a method to express the diagnosis reasoning rules by SWRL, combines the SWRL rules and C-F theory to realize semantic reasoning in the field of fuzzy inference under multiple conditions. The method is a useful exploration for Ontology application in the professional field, and lays the foundation for building intelligence system of diagnosis.

Research on Chinese Word Segmentation Optimization in Statistical Machine Translation
Shi Chongde, Wang Huilin
2012,
28
(4): 29-34. DOI:
10.11925/infotech.1003-3513.2012.04.05
Abstract
This paper analyzes the different segmentation approaches and how they work on word alignment of Statistical Machine Translation (SMT). Then it proposes two optimization methods of Chinese Word Segmentation(CWS) based on granularity constraint and sub-word tagging. Experiment results show that these methods can improve the quality of machine translation.

Mapping the Themes of Information Retrieval Based on Prefuse and Hierarchical Clustering
Xiao Ming, Li Wenchao, Xia Qiuju
2012,
28
(4): 35-40. DOI:
10.11925/infotech.1003-3513.2012.04.06
Abstract
In this paper, a thematic knowledge map framework using Prefuse is designed. Through the co-word analysis, hierarchical clustering and TreeML file conversion, the themes of information retrieval based on the framework are mapped. Finally, information retrieval research is divided into five themes: intelligent information processing, search engines related, user behavior, information system research and content-based information retrieval.

Research on User Interest Shift Aware Random Walk with Restart Recommendation Algorithm
Yu Yan, Qiu Guanghua
2012,
28
(4): 48-53. DOI:
10.11925/infotech.1003-3513.2012.04.08
Abstract
Aiming at random walk with restart recommendation algorithm ignoring user interest shift, this paper propses a new random walk with restart recommendation algorithm based on user interest shift. It identifies user interest by clustering, then creates user interest model on which estimates user's current interest concerning time decay. Finally, it forms the transition probability to make recommendation according to user current interest. Experiment shows that proposed algorithm can improve the recommendation accuracy efficiently.

Review on Normalization Methods of Citation Counts
Chen Shiji, Shi Liwen, Li Dongmei, Zuo Wenge
2012,
28
(4): 54-60. DOI:
10.11925/infotech.1003-3513.2012.04.09
Abstract
Citation counts is the most representative indicator in citation analysis,which is also used in research performance as an indicator of the impact. Since citation counts is sensitive on field, document type and publish year, it needs normalize for the cross-field comparison. In this paper,various methods of citation counts normalization are demonstrated and some problems on citation indicator in practice are also discussed.
